Test Methods for Fabric Physical Properties and How They Enhance Job Efficiency

By | home, News

In previous chapters, we discussed What Should You Understand About CE Test Standard for Protective Clothing, it stated clearly the standard definition of coverall and test methods for standard categorization. After we have grasped these standards, it is time to delve deeper into the fabric physical properties of the coverall, as these specific features will combine to form a qualified coverall that provides the best whole suit performance.


Fabric Physical Properties of Coverall

For coverall, it is more related to utility and durability as their production characteristics. Utility characteristics are changes in the wearing functions of a garment that occur when the fabric is subjected to a mechanical, thermal, electrical, or chemical force while being worn. While durability refers to the ability to maintain protection capabilities and wearing experiences until the maximum tolerance level is reached. It is the amount of stress that causes the fabric to break down or lose its ability to repeat a desired action or function.

Examples of Utility and Durability characteristics:

  1. Antistaticity
  2. Abrasion Resistance
  3. Flex Cracking Resistance
  4. Trapezoidal Tear Resistance
  5. Puncture Resistance
  6. Tensile Strength
  7. Seam Strength

Above we mentioned only examples of both utility and durability characteristics, you may find more details in the Performance Chart or Technical Data Sheets provided by the coverall manufacturer.


Test Methods for Fabric Physical Properties

We hereby introduce some fabric physical properties and their respective test methods used. By taking a peep at these test methods, you can understand how strict for a coverall to be CE qualified. CE certification assures users that the coverall has been independently assessed and the manufacturing process is maintained to comply with those standards.



Test Method – EN1149-1

To determine the resistance value of the fabric surface.

This specifies the electrostatic property requirements for safety garments to avoid incendiary discharge, which is especially important in areas where explosive atmospheres are risky.

Picture 1. Test Method for Antistaticity

Abrasion Resistance

Test Method – EN 530 (Method 2)

To determine abrasion or rubbing resistance of fabric.

This is a critical test performed to ensure that the garment is free of defects, has a long design life, and consistently performs well. The abrasive resistance ensures that it has the necessary strength to withstand the predominant friction forces that will be subjected to.

Picture 2. Test Method for Abrasion Resistance

Flex Cracking Resistance

Test Method – EN ISO 7854 (Method B)

To determine the fabric resistance to the formation and growth of cracks or damages by repeated flexing.

Clamp the fabric in grip and flex it constantly, then observe the cracking degree to realize or compare its flex-endurance after flexibility fatigued. It is a measure of garment toughness, specifically its resistance when subjected to flexing abuse.

Picture 3. Test Method for Flex Cracking Resistance

Trapezoidal Tear Resistance

Test Method – EN ISO 9073-4

To determine fabric resistance to tearing once damaged.

A force is applied to steadily extend a cut in the test fabric. This method is a tension test in which the strength is determined primarily by the fibers of the composite structure and their bonding or interlocking. It is useful for estimating the relative ease of tearing of nonwovens.

Picture 4. Test Method for Trapezoidal Tear Resistance

Puncture Resistance

Test Method – EN 863

To determine fabric resistance to being punctured by a force.

Puncture resistance denotes the relative ability of fabric material to inhibit the intrusion of a foreign object. The maximum force required to push the spike through the fabric is recorded as puncture resistance.

Picture 5. Test Method for Puncture Resistance

Tensile Strength

Test Method – EN ISO 13934-1

To determine the maximum load that fabric can support without fracturing when being stretched.

It is a procedure that uses a strip method to determine the maximum force and elongation at the maximum force of textile fabrics in equilibrium. Set the movable clamp in motion and extend the test fabric until it reaches the point of rupture.

Picture 6. Test Method for Tensile Strength

Seam Strength

Test Method – EN ISO 13935-2

To determine the strength of seam assembly in a garment.

This method specifies for the determination of seam maximum force of sewn seams when the force is applied perpendicularly to the seam.

Picture 7. Test Method for Seam Strength

These test results will then be evaluated and accepted by the Notified Bodies, which are authorized to issue a CE certificate for the qualified coveralls. The results of each test are based on a classification system described in EN 14325:2018, which includes all classification tables for fabric physical properties.


Fabric Physical Properties Can Enhance Your Job Efficiency

Users shall consider different fabric physical properties based on their job requirements in each application. Hereby listed few examples for reference.  

Chart 1. Considerations of Fabric Physical Properties

For users in construction, due to working environments, durability is the main concern, thus abrasion, trapezoidal tear or puncture resistance shall be considered. While for painting, do check on the flex cracking resistance and tensile strength, as you will need a lot of major movements thus any ruptures on the coverall may delay your working schedule. While in the oil and gas industry, users shall take note of the antistaticity as static electricity can create a tiny spark which in a flammable environment is sufficient to cause major explosions. Also, for those who carry out disaster management and disease control, considerations on tensile strength and seam strength are needed, as the conditions of the on-site environment will be full of unknowns.



There are always other aspects to consider when selecting an appropriate coverall in addition to these fabric physical properties. The final choice must be comprehensively evaluated instead of depending on a few values. For example, the coverall must also meet certain requirements such as chemical permeation resistance, ergonomic designs, etc. There are always many perspectives from which you can examine the appropriate coverall you should wear.

In the coverall world, there is a lot of knowledge to comprehend and these hidden features will lead you to select a more appropriate coverall for your daily jobs according to your needed protection levels. By paying attention to these details on Performance Chart or Technical Data Sheets, you will discover that there is no perfect coverall, but an appropriate one is the best companion to safeguard you while completing your jobs perfectly!

What Should You Know About Microporous Fabric Coverall?

By | home, News

When your working environment contains hazardous liquid such as blood, chemical liquid, or acids, wearing personal protective equipment (PPE) can keep you safe and reduce the risks of contact with the hazards. However, have you ever experienced sweating all over your body after a long day at work while wearing a coverall? To keep your comfort and efficiency and prevent the risky liquid at the workplace, wearing the coverall which is made by microporous fabric will be a popular solution.

What is the microporous fabric?

Microporous fabric is made up of nonwoven laminated microporous film, which is a light fabric that offers good breathability while remaining substantially impermeable to liquid. However, do you know how to maintain both breathable and liquid-proof at the same time?

To avoid liquid and blood penetration, the size of micropores is smaller than water drops and greater than moisture vapor. Besides, the winding holes are often stacked in several layers to allow moisture vapor molecules to flow while keeping liquids out. The micropore size of microporous fabric, for example, is on average 80-120 nm in diameter, which is 250 times larger than moisture vapor and 15,000-20,000 times smaller than a drop of water, as illustrated in Figure 1. This is how it manages the features of breathability and liquid protection.

Figure 1. ULTITEC Fabric Construction


The applications of microporous fabric include disposable items for medical, industrial, and consumer products, such as protective clothing, gowns, patient suits, coveralls, boots, and so on.

Coverall fabric structures

The fabric structures of the coverall also determine the breathability and liquid-proof function, which are compared in the table below by three fabric constructions: Multi-layer Spunbonded Melt-blown Spunbonded (SMS) fabric, Microporous film laminated PP nonwoven (PPSB), and Impervious PE coated fabric (PE Coated PPSB).

Coverall Fabrics Microporous Film
Laminate PPSB
Multi-layer SMS PE Coated PPSB


Liquid Protection

Table 1. Coverall fabric structures comparison

  • Microporous Film Laminate PPSB

It provides both premium breathability and liquid protection and can be used to handle hazardous liquids fluids, and the ability to allow water vapor to pass through the fabric will keep you comfortable at work.

  • Multi-layer SMS

It is more breathable than the other two, but it only provides limited liquid spray protection. However, it offers superior particulate protection and is appropriate to use when working with dust, asbestos, or construction.

  • PE Coated PPSB

Even though the special PE coated on PP nonwoven formula is not breathable, it provides an excellent external barrier against extremely dangerous hazards, directional liquid jets, and a wide range of chemicals. It can be used in petrochemical, oil and gas, and power plant, etc.

How to select an appropriate microporous fabric coverall?

After learning the facts about microporous fabric coveralls, you should consider 3 critical factors before choosing the appropriate one for your workplace.

1.  The quality of microporous fabric

A good-quality microporous film has small micropores and consistent pore distribution to resist liquid and fluid, and the moisture vapor can easily discharge through the multi-layer winding holes. In contrast, the poor quality of microporous materials will allow risky liquids to penetrate through the microporous film due to its large pores and inconsistent pore distribution.

Figure 2. Microporous film quality comparison

2.  Measurement of breathability

  1. You can choose breathable microporous fabric protective clothing to keep your body comfortable while working by looking at the Moisture Vapor Transmission Rate (MVTR) and Resistance to Evaporating Heat Transfer (Ret).

Moisture Vapor Transmission Rate (MVTR)

  1. It is a vapor barrier permeability measurement that refers to the rate at which sweat evaporates from the skin. Higher values indicate that vapor and moisture are removed more effectively, and it can be used to determine how comfortable a coverall is to wear.

Resistance to Evaporating Heat Transfer (Ret)

  1. It determines a material’s resistance to water vapor. In contrast to the MVTR, the lower the Ret value, the lower the resistance to moisture transfer and, as a result, the higher the breathability.

3.   Identify hazards and select the equivalent protection

Aside from liquid hazards, it may contain other types of hazards in the workplace. You should assess the hazards you will encounter daily and then choose an equal level of protection in accordance with Regulation (EU) 2016/425. Please refer to CE Standard for the categories of risks and related certifications, and also read the article of Instead of Getting a Coverall, “Going Home Safely” Is What We All Desire for more information.

Take the application of microporous fabric coverall for example. Approximately 50,000 liters of spilled oil, causing an oil slick to float on the sea and reach the Gulf of Thailand. Thousands of workers cleaned the contaminated beach to mitigate the damage caused by this devastation. In this scenario, a Type 4 EN 14605 spray tight suit that can protect against oil and saturated liquid splash would be a good choice because it provides the required protection against the harmful oil while also preventing any potential harm to people involved.


Microporous fabric is made of microporous film laminate PPSB and is designed to resist liquid while providing superior breathability. In terms of both breathability and liquid protection, microporous fabric coverall provides a better wearing experience than multi-layer SMS and PE-coated PPSB fabric coveralls. To select the appropriate microporous fabric coverall, please review the manufacturer’s technical information for comparing the quality and the breathability index such as MVTR and Ret Value. Besides, take into account the hazards at your workplace and select the equivalent protection level based on the CE standard from Regulation (EU) 2016/425. By doing so, you will be not only safe but also efficient at work.

ULTITEC Successfully Sparked Occupational Safety Attention at Press Event

By | home, News

The International Labor Organization (ILO) has proclaimed April 28 as “World Day for Safety and Health at Work” to encourage global prevention of occupational hazards and diseases. ULTITEC hosted an “Advocating Occupational Safety Press Event” and invited the representatives of Institute of Labor, Occupation Safety and Health, MOL, Taiwan Union of Nurses Association, Chang Jung Christian University, Fu Jen Catholic University, and National Yangming Jiaotong University jointly announced their intention to pay attention to occupational safety concerns, enforce corporate social responsibility, and ensure that every workplace worker returns home safely.

ULTITEC donated protective clothing to the three participating universities as teaching aids and offered lecture collaboration at the press event. We  expect that these potential frontline operators will embrace the proper concept of occupational safety and return home safely.

This year marks the 13th anniversary of ULTITEC. Previously, we had been through Ebola, avian flu, African swine fever, the Gulf of Mexico oil spill, the Fukushima nuclear disaster, and the Gulf of Thailand oil spill, etc. ULTITEC was protecting frontline workers so they could return home safely after the incidents. We fight alongside more than 150 million frontline heroes across 45 countries.

ULTITEC believes that what people want is not protective clothing, but to go home safely. Follow the three steps to go home safely will guide every frontline personnel to return home safe and sound.

Instead of Getting a Coverall, “Going Home Safely” Is What We All Desire

By | home, News

Some frontline people thought that as long as they wear personal protective equipment (PPE) at the workplace, they will be safe and fully protected. Is that correct? In January 2021, a doctor at Taoyuan General Hospital in Taiwan still became infected while treating COVID-19 patients while wearing full PPE. So, why was the doctor still got infected under full PPE covered?

Every worker wants to return home safe and sound after the task. A while ago, we have been educating The Golden Triangle Rules to Go Home Safely from Work. Whereas, in this article, we will focus on the crucial 3 Steps to Go Home Safely as (Figure 1.) below that you must follow to make sure safely home and keep hazards away from your family.

Figure 1: The 3 Steps to Go Home Safely


Step 1: Select appropriate protective clothing

Instead of being based on the sector, the risk enforcement requirements are based on the hazards present. Also, not every frontline worker will face the same dangers, and many harmful agents are imperceptible and have a long-term impact. Therefore, before deciding on appropriate protective clothing, the initial step is to identify your occupational risks and perform a hazard assessment, which is generally listed below.

  • Identify the hazards – discover what could be risky in the working environment.
  • Conduct Risk Assessment – understand the type of harm that the danger may cause, and the probability of it occurring.
  • Monitor risks – implement effective risk control measures.
  • Review on a regular basis and update as needed.

Take identifying the chemical hazards for example. The safety manager shall evaluate what hazards the frontline operators will encounter on their daily tasks. The common phases of chemical hazards are shown in Figure 2. These harmful agents may contact the skin in a variety of ways, including jets, sprays, splashes, soaks, and direct contact.

Figure 2. The common phases of chemical hazards

If these hazards are inevitable and will potentially be contacted by frontline operators, then the safety manager should consider the required coverall for them to minimize hazardous risk.  But how do you choose the appropriate coverall?

The protective clothing chosen should comply with Regulation (EU) 2016/425, which is the most rigorous PPE standard currently in effect. Then, select the types of coveralls according to the protection level needed as CE Standard, you can also find in What should you understand about CE test standard for protective clothing? Select an appropriate coverall in accordance with CE Standard and the equivalent protection level (Figure 3.) will help you minimize the occupational risks.

Figure 3. The protective level of protective clothing


Step 2: Correct donning and doffing process

After the selection of coverall, the next crucial step is correct donning and doffing procedures. For the removal of the coverall, it is relatively critical because frontline personnel may be contaminated if he accidentally contacts the hazards on the outside of the contaminated garment by taking it off improperly or carelessly.  As a result, frontline personnel must be trained on a regular basis to ensure their safety.

The correct donning and doffing instructions are advised by ULTITEC below.

  • Donning Processes


  1. Select appropriate coverall and read User Instruction thoroughly.
  2. Remove shoes and secure trousers into socks. Step into legs of coverall and place coverall over safety boots.
  3. Pull coverall towards arms and shoulders.
  4. Pull zipper halfway up. Put on a face mask (or respirator) and goggles. Pull hood over as head coverings. Cover sleeves over gloves.
  5. Zip up coverall to chin and ensure hood fits tightly to face, and seal storm flap with adhesive tape if any (Applicable for Type 3 and Type 4)
  6. Stretch to ensure coverall fits appropriately for ease of work movement and optimum protection.

Figure 4. ULTITEC Coverall Donning Instruction

  • Doffing Processes


  1. Remove adhesive tape (Applicable for Type 3 and Type 4)
  2. Unzip to the waist.
  3. Grab outer part and pull hood away from the head. Avoid contaminated gloves to touch the head.
  4. Release the first arm and strip off the glove from behind the back.
  5. Release the first arm from coverall and glove. Release second arm and glove from inside of coverall. Sit and roll down contaminated coverall from inside towards outside.
  6. Draw out legs from safety boots. Use a clean hand to remove goggles and face mask (or respirator) from behind. Fold or roll into a bundle and dispose of coverall responsibly.

Figure 5. ULTITEC Coverall Doffing Instruction

Please view the full instruction here or the video ULTITEC donning and doffing instruction.

Step 3: Correct disposal after usage

It is important to properly dispose of coveralls after they have been used and removed in order to prevent people from touching the used garment. The contaminated garments must be disposed of in the same manner as contaminated waste and in accordance with national regulations. According to the World Health Organization, medical waste, such as contaminated protective clothing, should be disposed of in a closed bin after being safely removed.


Here is the correct contaminated coverall disposal instruction after usage:

  1. Dispose of the used coverall separately from the rest of the trash.
  2. Make sure the garbage bag with the hazardous label is firmly fastened
  3. Place the bag in a lidded hazardous mark rubbish bin
  4. Hand over to professional cleaning staff for follow-up disposal

Figure 6. Lidded bin and fastened bag with hazardous label

Figure 7. The Professional cleaner takes the bin


Don’t assume you are invincible only by wearing a coverall. Your occupational safety cannot be guaranteed if you do not select appropriate protective clothing, do not initiate the donning and doffing process correctly, and do not dispose of it correctly after use. Remembering these 3 critical steps and putting them into action effectively will help you return home safely with full preparation for the next working day.



Appropriate Coverall Selection for Occupational Safety

By | home, News

Every year on April 28th, The World Day for Safety and Health at Work is celebrated to promote the prevention of work-related injuries. To manage occupational safety well, you can start by selecting appropriate coverall before entering the workplace. There are three important points prior to making a final decision.

 Identify your occupational risks.

If you need to shield yourself from a threat, find out if it is harmful particulates,  hazardous liquids, gas or vapor. You need to know your enemy before proceed to develop a strategy against it.

 Determine protection level needed.

Examine the physical states of the risks after they’ve been identified. Do you need antistatic to minimize particle adhesion if it is particulates? Alternatively, if it is a liquid, is it a saturated splash or a pressurized liquid jet?

Select both Product and Support Service.

Due to post epidemic era, PPE chaos is a challenge to overcome. Do look into Certifications, Technique Data Sheets, Comparison Charts or relevant technical support for a qualified coverall. Product and Support Service is equally important.
