1 Gaining a Competitive Edge With Performance Testing
2 Testing isn’t CheapBut the RIGHT Testing isa Good Investment
3 Start at the BeginningBefore addressing performance features, make sure your fabrics and products meet mandatory standards and customer expectations for quality.
4 Health & Safety Flammability Restricted substances Special children’s issues
5 Flammability16 CFR 1610: Standard for the Flammability of Clothing TextilesASTM D : Standard Test Method for Flammability of Apparel TextilesCPAI-75: A Rate of Burn Standard for Sleeping BagsASTM F (2005): Standard Test Method for Flammability of Sleeping BagsCPAI-84: A Specification for Flame-resistant Materials Used in Camping Tentage16 CFR 1615/1616: Standard for the Flammability of Children's SleepwearASTM D : Standard Test Method for Flammability of Textiles Used in Children's SleepwearOther national, state, and local regulationsIndustry standardsCPAI = Canvas Products Association International (Industrial Fabrics Association International)Applicable flammability regulations usually depend on end product
6 Note: Test method lists in this presentation are NOT comprehensive. For every AATCC method listed, there are similar, identical—or totally different—ISO, JIS, BS, etc. methods for measuring the same property.
7 Restricted Substances CPSIALead (children’s product ≤ 300 ppm; paint ≤ 90 ppm)Phthalates (toys and child-care items)Cal Prop 65: Safe Drinking Water and Toxic Enforcement Act of 1986American Apparel & Footwear Association RSLÖko-Tex Standard 100…Other government and industry RSLsformaldehyde, azo dyes, lead, BPA, etc.Legal requirements vary by country/state and product type. Further limits may be imposed by customers or certifying bodies.CPSIA 100 ppm lead limit to take effect in 2011 “if technically feasible”

12 Moisture Management Water resistance Absorbency Drying time Moisture transportWater/rain resistance/repellency: for outerwear, tents, sleeping bags, other items exposed to the elementsAbsorbency: for towels, items specifically intend to soak up waterVapor transport: what most mean by “moisture management;” movement of perspiration from skin to outside of garment for evaporation; multi-part process
13 Water Resistance AATCC TM22: Water Repellency-Spray Test Water is sprayed against the taut surface of a test specimen under controlled conditions. The specimen is evaluated by comparing the wetted pattern with pictures on a standard chart. This method is especially suitable for measuring the water-repellent efficacy of finishes applied to fabricsAATCC TM35: Water Resistance: Rain TestA test specimen, backed by a weighed blotter, is sprayed with water for five minutes under controlled conditions. The blotter is reweighed to determine the amount of water passing through the specimen. Tests at different intensities give a complete picture of the penetration resistance of a single fabric or combination of fabrics.AATCC TM42: Water Resistance: Impact Penetration TestMeasures the resistance of fabrics to the penetration of water by impact, and thus can be used to predict the probable resistance of fabrics to rain penetration resistance of garment fabric.AATCC TM70: Water Repellency-Tumble Jar Dynamic Absorption TestSubjects specimens to dynamic conditions similar to those encountered during actual use. Not intended for determining probable rain penetration resistance of fabrics, since it measures absorption of water into, but not through, the fabric. Results depend primarily on the resistance to wetting or water repellency of the fibers and yarns in the fabric, and not upon the construction of the fabric.AATCC TM127: Water Resistance: Hydrostatic Pressure TestMeasures the resistance of a fabric to the penetration of water under hydrostatic pressure.Keeping water outHydrostatic, impact, and rain test results depend on fiber, yarn, and fabric construction.

15 Absorbency AATCC TM 79: Absorbency of Textiles AATCC/ASTM Moisture Management Technical Supplement(MM TS) procedures (are not standard test methods. They have not been reviewed, balloted, or approved by the processes stated in the Rules of Procedure for AATCC Test Method and Technology Committees or ASTM International. Some of the techniques may be considered for development as new standards or incorporated into existing standards in the future.AATCC TM 79: Absorbency of TextilesThe completeness and uniformity of textile processing as well as the suitability of a fabric for a particular use is dependent upon its ability and propensity to take up water. The test is based on the amount of time it takes for a drop of water to disappear from the surface of a specimen (by being absorbed into the material).MM TS-01: Quick Water AbsorbencyDesigned to measure the water absorbency of textiles by measuring the time it takes for a drop of water placed on the fabric surface to be completely absorbed into the fabric. May be used to indicate comfort during wear, but most useful in measuring the affects of moisture control treatments used on textiles.MM TS-04: Absorbent Capacity – Absorbency Testing System (ATS)Measures water absorbency, rate, and direction with an infrared sensor to determine the maximum absorbent capacity of a fabric.Getting water in
16 Drying Time MM TS-05: Gravimetric Drying Test MM TS-07: Drying Time Determines the time for a fabric to dry when wet with a specified amount of water. Indicates drying time during wear or hang drying, but results may not be applicable in different temperatures and humidities.MM TS-07: Drying TimeDetermines drying time by wetting fabric and recording weight at set intervals until dry.MM TS-08: Drying Time of WetTextile FabricsA test specimen saturated in distilled water is placedinside a controlled atmosphere. Periodic weighingsdetermine the rate of water loss. Garment constructionis not considered.Getting water out
17 Moisture TransportAATCC TM 195: Liquid Moisture Management Properties ofTextile FabricsThe test method produces objective measurements of liquid moisture management properties of knitted, woven and nonwoven textile fabrics. Results are based on water resistance, water repellency, and water absorption characteristics of the fabric structure, including the fabric’s geometric and internal structure and the wicking characteristics of its fibers and yarns.MM TS-03: Horizontal WickingDetermines the horizontal spread or area of wicking of 0.5 mL ofdeionized water.MM TS-06: Vertical WickingMeasures the time for water to wick up six inches from a cut edge or thedistance wicked vertically in one hour.Moving water

21 Weather Resistance AATCC TM 16: Colorfastness to Light Accelerated exposure for color change evaluation only.AATCC TM 111: Weather Resistance of Textiles: Exposureto Daylight and WeatherTest specimens and standard are exposed simultaneously to natural weathering. End point is a specified degree of degradation (color change, strength loss, etc.) or a specific amount of radiant energy. Exposures by calendar days, months, or years can result in more variation.AATCC TM 169: Weather Resistance of Textiles: Xenon Lamp ExposureSample and standard are exposed to a xenon lamp source. Strength and/or color is compared.AATCC TM186: Weather Resistance: UV Light and Moisture ExposureSpecimens are exposed to a fluorescent UV light source and periodic wetting. Resistance to degradation is rated in percent loss in strength, or percent residual strength (breaking or bursting) and/or color change.AATCC TM 192: Weather Resistance of Textiles: Sunshine-Arc Lamp Exposure with and without WettingTest specimens and standard are exposed under specified conditions of relative humidity or wetting. Weather resistance is evaluated by comparison to unexposed original material.The relationship between any lightfastness test and the actual exposure in use must be determined and agreed upon by the contractual parties.
23 Stain ResistanceAATCC TM118: Oil Repellency: Hydrocarbon Resistance TestEvaluates resistance to wetting by a selected series of liquid hydrocarbons of different surface tensions. Drops are placed on the fabric surface and observed for wetting, wicking, and contact angle. The oil repellency grade is the highest numbered test liquid which does not wet the fabric surface.AATCC TM130: Soil Release: Oily Stain Release MethodMeasures ability of fabrics to release oily stains during home laundering. Primarily to evaluate the likely performance of soil release finishes in actual use.AATCC TM193: Aqueous Liquid Repellency: Water/Alcohol Solution Resistance TestDetermines the efficacy of a protective finish for imparting a low energy surface on all types of fabrics by evaluating resistance to wetting by a series of water/alcohol solutions of different surface tensions. Drops are placed on the fabric surface and observed for wetting, wicking, and contact angle.
25 Durability (abrasion resistance) ASTM D3884: Test Method for Abrasion Resistance of Textile Fabrics (Rotary Platform, Double-Head Method)Abradant wheels trace a circular pattern on the fabric specimen.ASTM D3886: Test Method for Abrasion Resistance of Textile Fabrics (Inflated Diaphragm Apparatus)Determines the resistance to abrasion of woven and knitted textile fabrics, both conditioned and wet, using the inflated diaphragm tester. Result is the number of cycles until the abrasive panel breaks through the fabric.ASTM D4157: Test Method for Abrasion Resistance of Textile Fabrics (Oscillatory Cylinder Method)Abrasion resistance of woven textile fabrics using the oscillatory cylinder tester. Common method for evaluating for upholstery.
26 DurabilityASTM D4158: Guide for Abrasion Resistance of Textile Fabrics (Uniform Abrasion)Every point in the surface of the specimen is equally and uniformly abraded in all horizontal directions. Evaluation options are fabric rupture, mass loss, thickness loss, and breaking strength loss.ASTM D4966: Test Method for Abrasion Resistance of Textile Fabrics (Martindale Abrasion Tester Method)The Martindale abrasion tester moves specimens in a Lissajous pattern against an abradant wool fabric. May not be suitable for fabrics with a pile depth greater than 2 mm.AATCC TM93: Abrasion Resistance of Fabrics: Accelerotor MethodSpecimen is driven along a zigzag course in a generally circular orbit within a cylindrical chamber, impinging on walls and abradant liner while being subjected to rapid, high velocity impacts. Evaluation is made on the basis of weight loss or grab strength loss of the specimen when broken at an abraded fold line.

30 Antimicrobial Activity AATCC TM30: Antifungal Activity, Assessment on Textile Materials: Mildew and Rot Resistance of TextilesThe dual-purpose test method determines the susceptibility of textile materials to mildew and rot AND evaluates the efficacy of fungicides on textile materials.AATCC TM100: Antibacterial Finishes on Textile Materials: Assessment ofOne of the most commonly used and well-recognized tests for antimicrobial-treated textiles, this method provides quantitative evaluation of the degree of antibacterial activity. Bacteria on treated and untreated specimens are counted after innoculation and incubation. Percent reduction by the treated specimen is calculated.AATCC TM147: Antibacterial Activity of Fabrics, Assessment of Textile Materials: Parallel Streak MethodThis test detects bacteriostatic activity on textile materials. The Parallel Streak Method provides quick and easy qualitative determination of antibacterial activity of diffusable antimicrobial agents on treated textile materials. This method provides evidence of antibacterial activity against both Gram positive and Gram negative bacteria.
