Antibacterial Textiles can prevent harmful bacteria from proliferating on fabrics and thus effectively reduce bacterial infection and related pathological changes that might adversely affect human health. Therefore, antibacterial treatments are widely applied in textile industry. Antibacterial Textiles find applications in products for households, furnishings, hygiene, cleansing and automobiles. Products include towels, socks, insoles, shoe linings, underwear, sportswear, leisurewear, shirts, blouses, work wear, medical garments, bedding, non-woven products and many others. The quantitative evaluation of antibacterial activity is judged by the bacteria reduction.

With current technology in Taiwan, antibacterial textiles for general use shall possess a Bacteriostatic Activity Value of at least 2.2 for quantitative test and there shall be existence of inhibiting halos for qualitative test (halo test). Bacteria used for testing are Staphylococcus aureus and the test method applied is JIS L1902.

This criterion is applicable to the evaluation and testing of antibacterial activity of textile for general use. The quantitative evaluation of antibacterial activity is judged by the percentage of bacteria reduction.

FTTS-FA-003 Electromagnetic Shielding Textiles

As everyone knows, many electronic devices such as cellular phones, computers and microwave ovens release electromagnetic waves. Based on the findings of studies and researches conducted by many domestic and international scholars and experts, it is very likely that electromagnetic wave harms human body but the problem is very easily neglected by most people.

Electromagnetic shielding textiles protect human body from such harm. They can be classified into three types:
1. Hybrid woven fabrics achieve electrical conductivity through twisting metallic fibers (which is thinner than human hair) with natural fibers or wrap natural fibers in metallic fibers to form electrically conductive composite yarns.
2. Conventional woven fabrics achieve electrical conductivity by undergoing finishing treatment processes such as electroless plating, sputtering and evaporation deposition. These processes fix electrically conductive metal particles on the surface of the fabrics to turn the fabrics into electrically conductive metallized fabrics.
3. Add conductive particles to polymers to form conductive filaments which are then spun into yarns and in turn woven into fabrics. The electromagnetic shielding effectiveness of such fabrics will not diminish even after many launderings.

Electromagnetic Shielding Textiles are usually graded into two classes – the Professional Use and the General Use. With current technology in Taiwan, general-use Electromagnetic Shielding Textiles can possess a shielding effectiveness (SE) up to a level of 30dB, while professional-use products can possess a shielding effectiveness from at least 30dB up to 50dB or higher.

This criterion is applicable to textiles in all forms, including woven, knitted, coated/laminated fabric and non-woven. To consider the durability, the pretreatment, ex: repeated laundering, weathering, may be required

3.1 The functional requirements in the test method are classified according to product end-use.

3.1.1 Class I--Professional use

for medical devices, safety uniform , shielding material for electronic component, assembly equipment and other application.

3.1.2 Class II--General use

for casual wear, uniforms (computer and telecom company), aprons, maternity dress,orprotective covers for consumer electronic products and other application.

(1) Class I － Professional use

(2) Class II － General use

Remark1：

SE： Shielding Effectiveness（dB）

ES： Percentage of Electromagnetic Shielding (%)

Remark 2：

Shielding Effectiveness (dB) can be calculated and converted into Shielding Effectiveness (%). Please refer to the Appendix Table for details.
1.2 General requirement for pretreatment

FTTS-FA-004 Moisture Transferring and Quick Drying Textiles

The quick drying capability of textiles (absorption of moisture and perspiration) is usually derived from profile fibers/fabrics, special weave structure or absorbent finishing. Textiles that transfer moisture and dry quickly mainly rely either on capillary action in their fibers/fabrics or moisture absorbency to quickly absorb moisture on skin surface and wick it away to textile surface. Affected by diffusion and air convection on textile surface, the moisture quickly evaporates, leaving the textile dry. These textiles are especially useful in hot climates or during intense workouts. They absorb huge amounts of perspiration, speed moisture to outer surface and keep the body dry. The capability of a textile to absorb water is called hygroscopicity and is measured by ‘wicking height’ and ‘water diffusion speed’. The capability of driving out sweat is known as ‘drying ability’ and is measured by ‘drying rate’.

Purpose and Scope

This criterion is applicable to evaluate the ability of moisture transferring and quick drying textiles in perspiration (simulated by water) transferring and quick drying.

3.1 The grading for the textiles performance in water diffusion ability

Table 1. The grading of water diffusion ability

3.2 The grading for the textiles performance in drying ability

Table 2. The grading of drying ability

3.3 The grading for the textiles performance in absorbency speed – dripping method

Recommendation: to meet the performance requirement of moisture transferring and quick drying textiles in absorbency, for knitted fabric the average time for no reflection of water droplet shall not be more than 2 seconds; for woven fabric the average time shall not be more than 5 seconds.

3.4 The grading for textiles performance in absorbency speed – Byreck method

To meet the requirement, both woven and knitted fabrics will have to reach the following standards in both warpwise (wale) and fillingwise (course) wicking heights.

FTTS-FA-006 Antifungal Textiles

These criteria are applicable to the evaluation and testing of antifungal activity of textile.

．Criteria :
Textile must achieve antifungal activity expressed by area of fungal growth (%) to grade C or above on 4 specified test organisms or on Trichophyton metagrophytes (ATCC 9533), after being washed for 50, 20, 10, or 5 cycles by an approved lab, or no washing required for disposable product so to meet the requirement set for FTTS-FA-006.

．Washing requirement：

．Classification of antifungal activity：

．Toxicity test：

The applicant must provide animal test reports with dermal irritation test (PII primary irritation index1000 mg/kg, no mortality nor abnormal symptom) for the antifungal finishing reagent used for the treated textile. This can also be provided by test report copy from a third party or guarantee letter from antifungal finishing reagent supplier.

FTTS-FA-007 Wrinkle Free Textiles

Cotton fabrics feature perspiration absorbency, softness and comfortableness. However, 100% cotton woven shirting, skirting and trousering are vulnerable to wrinkle, especially after laundering. Ironing is usually required to smooth away wrinkles and resume a flat, tidy appearance. Now, with the application of “wrinkle-free treatment for pure cotton fabric”, it’s no longer necessary to iron your pure cotton apparel every time after you wear it in order to maintain its smooth, wrinkle-free status – and such a nice status will withstand a whole day’s activities. This Easy Care function has allowed busy working people nowadays to lead an easier, happier life with more confidence. Moreover, the amount of free formaldehyde left in wrinkle free textiles is strictly regulated by legislative standards.

Current technology in Taiwan for Wrinkle Free Textiles sustains a grade of at least 3.5. The test method used is AATCC 143.

This criterion is applicable to the evaluation and testing of the smooth appearance of textile and apparel after repeated home laundering.

3.1 Smooth Appearance after 5 washes

3.2 Crease Retention after 5 washes

3.3 Seam Smoothness after 5 washes

3.4 Formaldehyde content

FTTS-FA-008 Ultraviolet Protective Textiles

1.Scope

This standard specifies the ultraviolet coefficient performance evaluation, and the basic
requirements of the standards and test methods evaluation for protective clothing (does not
apply to non-from UV Sunlight) for anti-solar ultraviolet textiles, clothing and other apparel
items (such as hats).

2. Definitions:
2.1.Ultraviolet Protection Factor, UPF: is defined as the ratio between "detected average
effective erythemal ultraviolet radiation flow (W/m2) with no skin protection from sample"
and "detected average effective erythemal ultraviolet radiation flow (W/m2) with skin
protection from sample".
2.2.Solar UV-A: solar ultraviolet radiation with wavelength between 315 and 400 nm.
2.3.Solar UV-B: solar ultraviolet radiation with wavelength between 280 and 315 nm.
2.4.Effective UVR transmission: ratio between "detected average effective erythemal ultraviolet
radiation flow (W/m2) with skin protection from sample" and "detected average effective
erythemal ultraviolet radiation flow (W/m2) with no skin protection from sample", expressed
in percentages.

FTTS-FA-009 Antistatic Textiles

Antistatic Textiles are mainly used to help human beings maintain work safety while working in an environment vulnerable to static interference. They are also used in operating rooms to prevent static electricity from interfering with major electronic medical devices. Moreover, in an environment with low humidity (very dry), garments on human body can produce a significant charge of static electricity due to friction. Antistatic textiles prevent human body from suffering the discomfort caused by static discharge.

Antistatic Textiles usually consist of metallic fiber blended with cotton, polyester, twisted or interwoven, as well as fiber containing “conductive carbon black“. For example, Nega-StatR by Barnet is a fine-filament bi-component yarn. Each filament has a unique, patented, “trilobal-carbon” conducting core surrounded by a sheath of polyester.

Four main measures are used to evaluate the antistatic function of textiles:
1. Surface resistance
2. Friction-charged electrostatic potential
3. Half-time
4. Decay time

With current technology in Taiwan, the friction-charged electrostatic potential of Antistatic Textiles can be as low as 1000 Volts or less (JIS L1094-B); their surface resistance can be as low as 1010Ω/sq or less (DIN 54345).

This criterion is applicable to textiles in all forms, including woven, knitted, coated/laminated fabric and non-woven. To consider the durability, the pretreatment, ex: repeated laundering, weathering, may be required.

3.1 Grade and Classification based on this specification

3.2 General requirement for pretreatment

Note 1
The treatment of washing durability may be varied upon agreement.

Note 2
The washing condition for Surface resistance and Decay time test should be based on AATCC 135; The washing method for Surface resistance test should be according to JIS L0217-103

FTTS-FA-010 Far Infrared Textiles

Far-infrared Ray is one band of the solar electromagnetic light-wave ranging in wavelength from 3μm to 1000μm. Far Infrared Textiles are made through adding special nano- or micron-sized ceramic powder to polymer before spinning.

Far-infrared materials can also be added during the dyeing or finishing treatment process of an ordinary fabric. After absorbing sunlight or heat from human body, Far Infrared Textiles will transform the energy into far-infrared with a wavelength of 4 to 14 μm and pass it back to human body. Far-infrared with a wavelength of 4 to 14 μm is known as the "light of life" or “biogenetic ray” and is capable of invigorating human physiology. Fabrics with far-infrared function can effectively achieve the purpose of thermal retention and are therefore ideal warm-keeping materials for activities in high-mountain or snowy areas.

Current technology in Taiwan for Far-infrared Textiles delivers an average far infrared emissivity of at least 0.85 and a temperature variation of at least 0.5℃. The test method for these textiles is not yet regulated internationally. Therefore, Taiwan Textile Federation simply uses domestically acceptable methods to test these fabrics.

This criterion is applicable to textiles except fibrous products and semi-products for medical use.

The far infrared textile processing includes mixing of raw materials, coating, lamination and submerging. As products made of mixing of raw materials deliver the same durability of the fiber, the wash-resistance test would not necessary. For products come of coating, lamination and submerging processes will have to have the 10 times wash-resistance test based on AATCC 135 (1) (III) (A) iii prior to conducting the performance test. The performance test is conducted in ambient temperature and the criteria are given as below:

FTTS-FA-011 Water Repellent Textiles

Water repellent fabrics are processed with water repellent additives, so that water form droplet and stay on fabric surface but do not spread on fabric surface or penetrate the fabric – a phenomenon known as “the lotus effect.” The efficiency of water repellency is graded in 5 ratings. A standard test is usually performed after five home launderings with water at 40℃. To qualify as water repellent, the fabric must perform to at least rating 4 (ISO), in other words, 90 or better efficiency (AATCC). Further tests for the durability of water repellency may be performed after 20, 50 or 100 launderings at similar temperatures. Water Repellent Textiles are well-suited to the face fabrics of windbreakers or other outerwear as well as umbrella fabrics, furnishing fabrics…etc.

With current technology in Taiwan, the initial water repellency of Water Repellent Textiles reaches 100 ; having undergone 100 launderings, their water repellency still reaches 80 or above. The test method employed is AATCC 22. The Optical Contact Angle of lotus leaf is 135°; fabrics processed by regular water repellent treatments can have an Optical Contact Angle up to 130°; fabrics processed by regular “nano super water repellent” treatments can have an Optical Contact Angle up to 140°. However, if we utilize a unique nanotechnology for functional textiles to modify the surface texture of fabrics, we will be able to impart an Optical Contact Angle up to 150° to the fabrics and surpass the technical level of most foreign countries as far as water repellency is concerned.

This criterion defines the evaluation and testing of water repellency textiles. It is applicable to textiles with water-repellent finishes. However it is not intended to measure penetration of water through the textiles.

FTTS-FA-013 Stain Release Textiles

Many materials that would permanently stain other materials are easily removed from Stain Release Textiles with only a laundering washing. Stain Release Textiles are made either by submerging or coating natural or synthetic fabrics in stain removal auxiliaries. Stain Release Textiles are commonly used in curtains, wall coverings, sofas, seat covers, windbreakers, aprons and many other applications.

Current technology in Taiwan for Stain Release Textiles achieves not less than rating 3.5.

This criterion defines the evaluation and testing of stain release textiles. It is applicable to measuring the ability of textile to release stain after home laundering.

Note 1 Washing condition should be according to AATCC 135(1)(III)(A)iii and washing cycles should bereferred to section 4.1 for durability consideration.

FTTS-FA-015 Flame-Resistant Textiles

With current technology in Taiwan, Flame-Resistant textiles have been able to meet the requirements of CPAI-84 and reach at least class 2 set forth in CNS10285. Phenomena measured are carbonized area, carbonized distance, after-flame time and after-glow time. The top grade for this test is Class 1 set forth in CNS10285.

Terminology:
2.1 Ignition time: The time for which the igniting flame is applied to a material.
2.2 After-flame time: The length of time for which a material continues to flame, under the specified test conditions, after the ignition source has been removed (also called duration of flame).
