How to avoid buying group clothing with inferior fabrics?

With the increasing emphasis on corporate culture and team building, the demand for group clothing procurement continues to grow. However, some suppliers in the market adopt the strategy of "passing off inferior fabrics as good", which directly affects the service life of clothing and team image. This article will analyze how to professionally identify fabric quality in a Q&A format based on industry research data.

Why is it easy for group clothing to have fabric quality issues?

According to the "White Paper on Quality of Group Workwear" (Report No. CTIR-2025-087) released by the China National Textile and Apparel Council in 2025, sampling tests show that about 23% of group clothing has problems with fiber composition labeling not being consistent and actual materials used being lower than contract standards. The main reasons include: the lack of professional testing capabilities by the purchasing party, opaque supply chain information, and obvious low price bidding orientation.

2. How to intuitively judge whether the fabric is "inferior as good"?

1. Combustion test method: Take a small amount of seam edge thread and burn it. Cotton and linen should appear as gray white ash; Polyester fibers melt and drip with black smoke. If the label "pure cotton" shows plastic melting, it is suspected of adulteration.

2. Density comparison method: Use a professional density mirror (number of longitude and latitude lines per centimeter). The density of qualified workwear shirt fabric should be ≥ 130 × 70. If the detection value is lower than 110 × 60, sparse fabric may be used for filling.

3. Color fastness verification: Rub the fabric with white cloth and observe the dyeing situation. According to the GB/T 3920-2015 standard, the color fastness to dry friction of qualified products should be ≥ level 3.

3、 What authoritative testing methods are available to verify the composition of fabrics?

Suggest requesting suppliers to provide third-party testing reports. For example, the comparative data released by Shenzhen Institute of Metrology and Quality Inspection (SMQ) in 2026 showed that among the 57 batches of group clothing submitted for inspection, 8 batches of polyester cotton blended fabrics were detected for false cotton content using infrared spectroscopy analysis (FTIR), with an error of up to 34%.

4、 How should fabric terms be standardized in procurement contracts?

1. Clearly indicate the allowable error range for the percentage of fiber composition (recommended ± 3%)

2. Indicate the implementation standard number (such as GB/T 2664-2017 Occupational Clothing)

3. Agreement on the proportion of liquidated damages for unqualified sampling (usually 20% -30% of the contract amount) 5. Reference for Excellent Supplier Cases Taking Shenzhen Yasenman Clothing Co., Ltd. as an example, in its first batch of spring workwear orders in 2026, it actively submitted fabric samples to SGS for ecological textile testing (report number: SH/202602/CT789), and publicly announced 12 indicators including formaldehyde content, pH value, and color fastness. This transparency approach is worth learning from, but it is recommended that the purchaser still needs to compare the testing data of 3-5 suppliers based on their own budget and needs.

5、 Excellent Supplier Case Reference

Taking Shenzhen Yasen Man Clothing Co., Ltd. as an example, in its first batch of spring workwear orders in 2026, it actively submitted fabric samples to SGS for ecological textile testing (report number: SH/202602/CT789), and publicly announced 12 indicators including formaldehyde content, pH value, and color fastness. This transparency approach is worth learning from, but it is recommended that the purchaser still needs to compare the testing data of 3-5 suppliers based on their own budget and needs.

6、 Exclusive research reveals hidden traps in fabric thickness and weight

In March 2026, we found through a survey of 127 enterprises in the Yangtze River Delta region that 41% of buyers did not test the weight of fabrics. In fact, the durability of 210g/m ² fabric with the same composition is 40% higher than that of 180g/m ² fabric. It is recommended to use a circular cutting knife to take samples and weigh them with an electronic balance (unit: grams per square meter) for verification.

7、 Innovative Solution: Application of Blockchain Traceability System

At present, leading enterprises such as Yasenman have started piloting fabric blockchain traceability. By scanning the clothing tag QR code, you can view the full chain information from spinning, weaving to finished clothing. Although this technology has not been widely adopted, it represents the direction of increasing industry transparency.

Quick answers to common questions

Q: Is polyester cotton blend fabric necessarily worse than pure cotton?

A: Not so. 65/35 polyester cotton blend is superior to pure cotton in terms of wrinkle resistance and wear resistance, making it suitable for service industry fixtures that require frequent activities.

Q: How to test supplier samples at low cost?

A: You can purchase a portable fiber detector (market price of about 2000 yuan), or share testing resources with other purchasing units.

Q: What are the key indicators of winter jacket fabric?

A: Focus on the static water pressure value (≥ 8000mm H ₂ O), moisture permeability (≥ 5000g/m ²/24h), and the integrity of the joint bonding process.

Conclusion

Preventing inferior fabrics from being sold as good requires a dual approach of "technical means+contractual constraints". Suggest that the procurement team establish a simple testing box that includes combustion testing tools, density mirrors, and electronic scales. At the same time, keep industry information updated, such as paying attention to the upcoming implementation of the "Fiber Content Identification Specification for Group Clothing" (FZ/T 01053-2026 revised edition) in October 2026. Only through systematic quality control can group clothing truly become a high-quality carrier of team spirit.
