Textile Perspiration Color Fastness Tester is a testing device specially used to evaluate the color stability of textiles after contact with sweat. It simulates the effect of human sweat (acidic or alkaline) on fabrics to detect whether dyes will fade, migrate or stain to ensure that the textiles maintain color durability during wearing or washing.

Main Purpose

1. Evaluate the perspiration color fastness of textiles

Test whether textiles (such as clothing, home textiles, sports fabrics, etc.) fade or stain after being soaked in sweat to ensure that they meet industry standards (such as AATCC 15, ISO 105-E04, GB/T 3922, etc.).

2. Optimize dyeing process

Help textile printing and dyeing enterprises improve dye formula and color fixing process, improve product color fastness level, and reduce color migration problems caused by sweat stains.

3. Ensure clothing quality and consumer safety

Prevent sweat from causing dye to fall off and stain the skin, especially suitable for close-fitting textiles such as infant clothing, sportswear, underwear, etc., to ensure safety and comfort.

4. Meet international testing standards

Used for third-party testing institutions, laboratories and corporate quality control to ensure that products meet the color fastness requirements of markets such as Europe, the United States, and Japan when exported (such as OEKO-TEX®, REACH regulations).

5. Research new functional fabrics

Test the color stability of functional fabrics such as antibacterial, deodorant, moisture absorption and perspiration in sweat environments to verify their durability.

Test principle

The tester usually simulates human sweat (artificial sweat is divided into acidic and alkaline types), fits the textile sample with a standard adjacent fabric (such as cotton, wool, etc.), keeps it at a specific temperature (such as 37±2℃) and pressure for a certain period of time, and then evaluates the discoloration of the sample and the staining of the adjacent fabric, and rates it according to a standard color card (such as a gray card) (1-5 levels, 5 is the best).

Applicable industries

Textiles and clothing: ready-made clothes, sportswear, underwear, socks, etc.

Home textiles: sheets, towels, curtains, etc.

Shoe materials: upper fabrics, linings, etc.

Testing agencies: quality inspection centers, third-party laboratories

Summary

Perspiration color fastness tester is a key equipment for quality control in the textile industry. It can effectively prevent fading problems caused by sweat, improve product quality and market competitiveness, and ensure consumers' health and comfort experience.
