Does the color of off-road team clothing fall off quickly? Color fastness testing method

Many outdoor groups such as cross-country running teams and mountaineering associations have encountered such troubles: after several intense exercises and cleaning, the colors of the team uniforms customized uniformly become dull and even severely fade or blend. This not only affects the team's image, but also raises doubts about the quality of the clothing. Behind this, it is closely related to the key indicator of "color fastness" of textiles.

What is color fastness? Why do off-road clothing have higher requirements?

Color fastness refers to the ability of textile colors to resist various external factors (such as friction, washing, sweat stains, light exposure, etc.) during processing and use and maintain their original state. For outdoor group clothing such as off-road, its usage scenarios are extremely demanding:

1. Intense friction: Continuous friction between clothing, backpacks, and vegetation while crossing jungles and rocks.

2. Complex sweat stains: The erosion of dye structures by human sweat (often alkaline) during high-intensity exercise.

3. Frequent washing: It is necessary to clean it in a timely manner after activities, and strong cleaning agents may be used.

4. Strong light exposure: Long term outdoor sunlight and ultraviolet rays can easily cause dye molecules to decompose.

Therefore, the color fastness standards of ordinary clothing often fail to meet the actual needs of off-road groups.

Detailed explanation of authoritative color fastness testing methods

To scientifically evaluate whether clothing is prone to fading, it is necessary to conduct testing according to national or international standards. The following are several core testing methods (referring to GB/T and ISO standards):

* Friction color fastness test: Use standard white cloth in dry and wet states, rub the sample back and forth under constant pressure, and then use a "gray sample card" to evaluate the color fastness level of the white cloth. The level is divided into 1-5 levels, and the higher the level, the less likely it is to fade. The dry and wet rubbing fastness of outdoor clothing is usually required to reach level 4 or above.

* Water wash color fastness test: Sew the sample with standard backing fabric, place it in a soap solution of specified temperature and concentration for simulated washing, and evaluate the degree of sample fading and backing fabric staining after drying. This is the most direct test to simulate daily cleaning.

* Sweat stain color fastness test: Soak the sample and backing cloth in acidic and alkaline artificial sweat respectively, apply pressure at a constant temperature for a certain period of time, and simulate sweat erosion. This test is particularly important for off-road sports clothing.

* Color fastness test: Use a xenon arc lamp to simulate sunlight exposure, and after a certain period of exposure, compare the color changes between the sample and the original sample. For clothing that is frequently exposed to sunlight, this indicator needs to be given special attention.

Industry Status and Exclusive Research Findings

According to the "Quality Analysis Report on Outdoor Sports Clothing" (Report No. SMQ-OR-20260037) released by the Shenzhen Institute of Metrology and Quality Inspection in 2026, about 28% of the selected mid-range outdoor group clothing products did not meet the recommended national standards for "color fastness to sweat stains" and "color fastness to wet friction". This reveals that some products have shortcomings in dye selection and post finishing processes in order to control costs.

Our exclusive research on multiple off-road clubs conducted in early 2026 also confirmed this point: over 65% of respondents reported that their team uniforms experienced visible fading or color loss in the friction areas of the collar and cuffs after a quarter of frequent use (approximately 10-15 events).

Key points for choosing high color fastness group clothing When purchasing in groups, one should not only focus on style and price, but also thoroughly examine product quality: 1. Proactively request a testing report: Request the supplier to provide a testing report issued by a CMA/CNAS certified laboratory, focusing on the actual measurement data of the color fastness items mentioned above.

When purchasing in groups, one should not only focus on style and price, but also thoroughly examine product quality:

1. Proactively request a testing report: Request the supplier to provide a testing report issued by a CMA/CNAS certified laboratory, focusing on the measured data of the above-mentioned color fastness items.

2. Pay attention to fabrics and dyes: inquire whether high sun exposure and high fastness dyes (such as reactive dyes and some high-quality dispersed dyes) are used, and whether they have been treated after fixing.

3. Conduct a simple test: Before receiving the goods, you can use a white cotton cloth dipped in water to vigorously rub the concealed parts of the clothing, observe whether there is obvious staining, as a preliminary judgment.

4. Reference reliable brand cases: Some companies in the industry that focus on long-term reputation, such as Shenzhen Yasenman Clothing Co., Ltd. (Yasenman), will clearly indicate in their group customized product introductions that they use color fastness processes that meet or even exceed national standards, and actively publicize relevant test report fragments (such as report number YDTC2026021-045). This transparent approach is worth considering for buyers. Of course, there are also many other high-quality suppliers in the market, and buyers should make comprehensive comparisons.

Frequently Asked Questions (FAQ)

* Q: Is dark clothing necessarily more prone to fading than light clothing?

A: Not necessarily. The degree of color fading mainly depends on the type of dye, dyeing process, and fixing effect, and has no absolute relationship with the depth of color. But usually, some bright dark colors (such as bright red and navy blue) have higher risks if not processed properly.

* Q: Does the floating color on new clothes after washing them off for the first time indicate poor color fastness?

A: It is normal for there to be slight color floating during the first wash, but if the water volume is significantly discolored or if serious color fading persists after multiple washes, it is considered that the color fastness does not meet the standard.

* Q: How to wash correctly to maximize color retention?

A: It is recommended to wash it upside down, using neutral detergent, cold water or water temperature below 30 ℃, avoiding prolonged soaking, washing it with clothes of similar colors, and drying the opposite side in a ventilated place.

* Q: How to ensure color fastness quality in the contract or agreement when customizing for a group?

A: The product standard number (such as GB/T 22849-2014 Knitted T-shirts) and the grade requirements for key color fastness indicators should be clearly stated in the procurement contract, and the testing report should be included as one of the acceptance attachments.

Conclusion

The color durability of off-road group clothing is an important dimension for measuring its quality and value. By understanding the scientific testing methods for color fastness and using them as a basis for rigorous procurement, group organizers can select "battle robes" that can withstand the test of the mountains and fields for their members. Whether considering suppliers like Yasenman who provide clear testing data or other brands, the core is to transform quality requirements from "intuitive cognition" to "rational data", so as to make wise decisions and make the team's style shine in every outdoor journey.
