Does your clothing fade after washing? Does it turn yellow after prolonged exposure to sunlight? Does it stain when wet with sweat? These are all issues related to the color fastness of textiles, which are closely linked to the raw materials, production, and processing of textiles and clothing. They are also one of the items with a high failure rate in quality inspections. Therefore, testing the color fastness of textiles is a routine testing item in many standards.

1. What is colorfastness of textiles?

Textiles are subjected to various external influences during use, such as compression, friction, and washing. Some dyed textiles also undergo special finishing processes, such as resin finishing, flame-retardant finishing, sandwashing, and brushing. In such cases, it is essential that the colorfastness of dyed textiles remains relatively stable. This is referred to as colorfastness, and testing for colorfastness is an important method for assessing the degree of color fading.

2.What are the standards for textile colorfastness testing?

Colorfastness to washing: DIN EN ISO 105-C06, AATCC 61

Colorfastness to water: DIN EN ISO 105-E01, AATCC 107

Colorfastness to perspiration: DIN EN ISO 105-E04, AATCC 15

Colorfastness to perspiration measures a textile fabric's ability to maintain color stability without fading or bleeding when exposed to human sweat. It is a critical parameter in textile quality testing. Human sweat is a complex mixture containing water, salts (such as sodium chloride), lactic acid, urea, and other components. These elements may chemically react with dyes in the fabric or cause dye migration under the influence of sweat's moisture and temperature, thereby affecting the fabric's appearance and lifespan. This indicator directly impacts the wear experience and durability of garments, being particularly critical for intimate apparel (such as underwear and sportswear) and infant/toddler clothing.

1. Purpose of Sweat Resistance Testing

Sweat resistance testing methods evaluate a material's color durability when exposed to prolonged contact with human perspiration. This is critical for products in close contact with the body, such as apparel, footwear, and accessories. The test simulates the effects of sweat on materials over time, enabling manufacturers to assess colorfastness under real-world usage conditions.

2. Operating Procedure for Sweat Color Fastness Tester

The GT-D09 Sweat Color Fastness Tester is suitable for assessing the sweat color fastness of various textile materials, dyed fabrics, and colored textiles. It evaluates resistance to sweat, water, seawater, saliva, chlorine bleach, and phenolsulfonated ethylamine.

Sweat fastness testing follows various international standards, such as ISO 105-E04, AATCC 15, and JIS L 0848. The test involves immersing textile or leather samples in a synthetic sweat solution containing specific concentrations of salts and acids to mimic human sweat composition.

The samples are then placed in an oven at a set temperature and humidity for a specified duration (typically 4-24 hours). After the sweat exposure period, samples are rinsed and dried, then evaluated for color change or staining using a gray scale or colorimeter. This test assesses color transfer from the material to other surfaces, as well as fading or discoloration of the material itself.

Sweat colorfastness test results are reported on a scale of 1-5 or 1-8, with higher numbers indicating greater resistance to sweat staining. This test is commonly used in the textile and leather industries to ensure products maintain their appearance and quality during use.

3. Significance of Sweat Testing in Textile Testing Methods

Sweat testing within textile testing methods holds significant importance in the textile and leather industries, as it provides manufacturers and consumers with valuable information regarding material quality and performance under real-world usage conditions. High levels of sweat colorfastness indicate that materials are less likely to fade or stain when exposed to perspiration, making them more durable and long-lasting.

Sweat fastness testing methods are standardized to ensure consistency and accuracy across different laboratories and testing facilities. This enables manufacturers to ensure their products meet industry standards and comply with regulations. Furthermore, this testing method can be used to identify potential quality issues in materials before incorporating them into finished goods, allowing manufacturers to address and correct any problems before they reach consumers.

4. Features of Sweat Fastness Testing Equipment

4.1. Steel frame and weight bags are constructed from 316L stainless steel, offering acid and alkali resistance with long-term corrosion resistance.

4.2. The sweat fastness tester provides ISO and AATCC acrylic separator plates.

4.3. The perspiration tester supplies ISO and AATCC standard pressing weights.

4.4. Perspiration testing requires the use of a high-precision drying oven.

Sweat resistance testing instruments represent only one of several methods used to evaluate the colorfastness of textiles and leather goods. Additional tests, such as wash fastness, lightfastness, and rub fastness, can be conducted to gain a more comprehensive understanding of a material's color durability.

Wash fastness testing involves subjecting materials to repeated washing cycles to assess resistance to fading or staining. Lightfastness testing exposes materials to artificial or natural light to evaluate resistance to fading. Rub fastness testing involves rubbing one material against another surface to assess resistance to color transfer.

6. Conclusion

In summary, the perspiration colorfastness test method is a crucial assessment technique used in the textile and leather industries to evaluate a material's resistance to fading or staining when exposed to human perspiration. This standardized test ensures consistency and accuracy, providing manufacturers and consumers with valuable information about a material's quality and performance under realistic conditions.

1. What is yarn evenness testing?

Yarn evenness testing, in simple terms, is the measurement of the uniformity of yarn thickness along its length. As the basic raw material for textile products, the quality of yarn directly impacts the performance and appearance of subsequent textile products. Yarn evenness, as one of the key indicators of yarn quality, directly affects the quality of textile products.

2. The significance of yarn evenness testing

Conducting yarn evenness testing serves multiple important purposes. On one hand, it helps assess the quality level of yarn. Yarn with even thickness ensures clear fabric patterns, uniform color, and reduced defects during subsequent processing. For example, in weaving processes, uneven yarn may cause defects such as horizontal bands or clouding in the fabric, severely affecting its aesthetic appeal and practicality. On the other hand, testing can promptly identify issues in the spinning process, helping manufacturers adjust process parameters, optimize production workflows, improve production efficiency, and reduce production costs. For instance, if test results indicate that uneven yarn evenness is caused by a malfunction in the draw-off mechanism of the ring spinning machine, the company can target repairs or adjustments to the draw-off mechanism to improve yarn quality.

3. Yarn Evenness Testing Methods

In practice, there are several methods available for testing yarn evenness.

Among these, the traditional visual inspection method involves experienced inspectors directly observing the appearance of the yarn with the naked eye to assess its evenness. While this method is simple and straightforward, it is highly subjective, as different inspectors may have varying criteria for judgment, and it may be difficult to accurately detect subtle unevenness in the yarn.

The capacitive yarn evenness tester method utilizes the difference in dielectric constants between yarn and air. As yarn passes through capacitive plates, the capacitance value changes with yarn thickness. By detecting changes in capacitance, the method reflects yarn evenness. This method offers fast testing speed and high precision, accurately measuring unevenness in short yarn segments.

Another method is the photoelectric yarn evenness tester, which is based on the varying degrees of light obstruction by the yarn. It converts light signals into electrical signals through photoelectric conversion and then analyzes the yarn's evenness. This method is sensitive to changes in the yarn's surface morphology and can effectively detect defects such as yarn fuzz and details.

4. Yarn Evenness Testing Criteria  

In yarn evenness testing, there are a series of important criteria used to quantify the test results. The Average Deviation Coefficient (U%) is one of the commonly used criteria, reflecting the degree of deviation between the actual linear density of each segment of the yarn and the average linear density. The smaller the U% value, the more uniform the yarn evenness. The coefficient of variation (CV%) is also used to measure yarn unevenness, similar to the average deviation coefficient, but with a slightly different calculation method. A lower CV% value indicates better yarn quality. Additionally, there is the blackboard yarn evenness test, which involves winding the yarn around a blackboard and comparing it to a standard sample to evaluate the yarn's evenness grade, categorized into superior, first-class, second-class, etc. A higher grade indicates better yarn evenness.

In the entire textile industry, yarn evenness testing plays a crucial role. From spinning mills to weaving mills, and then to garment processing factories, each stage has strict requirements for yarn evenness. For spinning mills, good yarn evenness test results indicate that the yarn they produce is of high quality, capable of meeting the needs of downstream enterprises, thereby enhancing the company's market competitiveness. Weaving mills use yarn with uniform evenness to produce stable-quality, aesthetically pleasing fabrics, reducing defect rates and improving economic efficiency. Garment processing plants utilize high-quality yarn fabrics to create comfortable, stylish clothing products that appeal to consumers. In summary, yarn evenness testing runs throughout the entire textile supply chain, serving as a critical component in ensuring textile quality and promoting the healthy development of the textile industry.

The most commonly tested properties include wash resistance, light resistance, abrasion resistance, sweat resistance, ironing resistance, and climate resistance. In practice, the specific testing items are determined based on the product's intended use and product standards. For example, knitted underwear is tested for sweat resistance, while outdoor textiles (such as sunshades, billboard fabrics, and canopy materials) are tested for climate resistance.

1.Sunlight Fastness

Textiles are typically exposed to light during use, and light energy can degrade dyes, leading to the well-known phenomenon of “fading,” causing colored textiles to change color—generally becoming lighter or darker—and in some cases, altering their color tone. Therefore, it is necessary to test for colorfastness. Sunlight fastness testing involves exposing test samples alongside blue wool standard fabrics of different fastness grades under specified conditions to sunlight. The test samples are then compared with the blue wool fabrics to evaluate their sunlight fastness. The higher the grade of the blue wool standard fabric, the more light-resistant it is.

2.Wash fastness

The sample is sewn together with a standard backing fabric, washed, rinsed, and dried under appropriate temperature, alkalinity, bleaching, and friction conditions to obtain test results in a short period of time. The friction is achieved through rolling and impact of stainless steel balls in a small bath ratio, and the results are rated using a gray card. Different testing methods have different temperature, alkalinity, bleaching, and friction conditions, as well as sample sizes. Specific selections should be made based on testing standards and customer requirements.

3. Rubbing color fastness

Place the sample on a rubbing fastness tester and rub it with a standard rubbing cloth under a certain pressure for a specified number of times. Each group of samples must undergo both dry and wet rubbing color fastness tests. The color transferred onto the standard rubbing cloth is graded using a gray scale, and the resulting grade represents the measured rubbing color fastness. Friction colorfastness requires both dry and wet friction tests, and all colors on the sample must be subjected to friction.

4. Dry cleaning color fastness

Similar to water washing color fastness, except that water washing is replaced with dry cleaning.

5. Sweat stain color fastness

Sew the sample to the standard backing fabric, treat it in sweat stain solution, clamp it in a sweat stain color fastness tester, place it in an oven at a constant temperature, then dry it, and rate it using a gray card to obtain the test results. Different test methods have different sweat solution ratios, different sample sizes, and different test temperatures and durations.

6. Non-chlorine bleach colorfastness

The fabric is washed under non-chlorine bleach washing conditions, and the degree of color change is evaluated, which is the non-chlorine bleach colorfastness.

7. Pressing color fastness

Cover the dry sample with a cotton backing fabric, then press it for a certain period of time in a heating device at a specified temperature and pressure. Evaluate the discoloration of the sample and the color transfer to the backing fabric using a gray sample card. There are three types of heat pressing color fastness: dry pressing, damp pressing, and wet pressing. The specific test method should be selected based on different customer requirements and test standards.
