Shanghai Municipal Supervision: The detection rate of unqualified leather clothing in supervisory spot inspections is 15%
The Shanghai Municipal Administration for Market Regulation announced on the 13th that in response to consumer complaints, reports and products with many quality problems, the bureau has recently concentrated on The organization conducted supervision and random inspections on 40 batches of leather clothing of 39 brands sold by 7 companies in 5 districts of Shanghai: Yangpu, Huangpu, Xuhui, Minhang, and Qingpu. After testing, 6 batches were found to be unqualified. The unqualified detection rate is 15%.
According to reports, the testing items involve 9 categories including pH value, free formaldehyde in leather, decomposable harmful aromatic amine dyes in leather, odor, formaldehyde content in textiles, and decomposable carcinogenic aromatic amine dyes in textiles. The unqualified items in this supervision and spot inspection are mainly three items: tearing force, fiber composition allowable deviation, and rubbing color fastness.
First, the tearing strength was unqualified, and there were 3 batches. For example, New World Department Store (China) Co., Ltd. sells a certain brand of women’s leather tops (model specifications: 165/84A) produced (or supplied) by Guangdong Gedi Fashion Apparel Research and Development Co., Ltd. in Paris Printemps (Wujiaochang store); Model number: 5400509-4208411-001), the actual tearing force is 6N (standard value should be ≥9N), which is inconsistent with the standard requirements. Tear force is an important physical and mechanical property of leather. If this indicator fails, the garments are prone to tearing, damage, etc., which directly affects the service life.
Second, the color fastness to rubbing was unqualified, and there were 2 batches. For example, Shanghai Outlet Brand Direct Sales Plaza Co., Ltd. sells a certain brand of leather jacket (model specification: 46 (170/ 92B); Style number: FRFLT030T BK). The actual measurement of the rubbing color fastness (wet rubbing) of leather fabrics is that the cuff longitudinal direction: Level 2, the cuff transverse direction: Level 2, other longitudinal directions: Level 2/3, other transverse directions: Level 2 (standard The values should all be ≥ level 3), which is inconsistent with the standard requirements. This indicator is unqualified. In daily use of leather goods, due to friction, the surface coating will be damaged, peeled off, and discolored, which will cause discoloration and color migration of the leather goods, affecting the appearance quality.
Third, the allowable deviation of fiber composition failed, and there were 2 batches. For example, Shanghai Huijin Department Store Co., Ltd. sells a certain brand of leather jackets (model specifications: 160/84A(38); style number: SLCWF432) that are nominally produced (or supplied) by Shanghai Sanrun Clothing Co., Ltd., and the lining composition is The actual measurement is 51.0% polyester fiber and 49.0% viscose fiber. The company clearly stated that it is 100% polyester fiber (the standard tolerance value should be ±5%), which is inconsistent with the standard requirements. The fiber component refers to the composition and content of the raw materials used in the product, which reflects the inherent characteristics and value orientation of the product. Wrong or random labeling of fiber content can easily mislead consumers.
Based on the results of supervision and spot inspections, the Shanghai market supervision department has ordered relevant operators to immediately stop selling substandard products, conduct a comprehensive cleanup of inventory products and products on sale, and transfer operators who produce and sell substandard products to local market supervision The department will investigate and handle the matter in accordance with the law. At the same time, the Shanghai market supervision department reminds consumers to pay attention to the following points when purchasing leather clothing:
1. Appearance. The leather should have good luster and should be dyed evenly without color difference. The surface should be smooth, with fine skin texture, bright and soft color, and should not be extremely shiny or dull. Patterns and pores can be seen on the surface of natural leather, and they are unevenly distributed; synthetic leather generally has no pores on the surface, or has artificial regular patterns and consistent pores. Under natural light, the surface layer of leather clothing should be free of insect spots, mildew spots, repair spots, damage, etc.
2. Feel. The leather feels full, smooth, soft and elastic, and the thickness should be even. Real leather is composed of natural uneven fiber tissue. When bent at different parts, the thickness, number, and texture of the creases produced will be obviously uneven; synthetic leather feels like plastic and has poor recovery properties. The thickness of the folds are similar.
3. Odor. Generally, genuine leather has a unique smell without any unpleasant smell, while imitation leather has a plastic smell. Poorly tanned leather will emit unpleasant odors, and leather odors are difficult to dissipate and difficult to remove.
4. Maintenance. Since the main component of cowhide, sheepskin, and pigskin is protein, they are prone to moisture, mold, and insects. therefore. When wearing leather clothing, you should avoid contact with oil, acid, alkaline and other substances, and you should also pay attention to moisture. Once leather clothing becomes damp and moldy, it will lose its luster and affect its fastness.
5. Storage. Leather clothing should be anti-wrinkle and anti-fracture, and folding and heavy pressure should be avoided as much as possible when storing. When wrinkles appear on leather clothing, you can use a non-steam iron. Place a piece of silk or cotton lining on the leather clothing and gently iron the wrinkles back and forth at medium-low temperature. Do not touch the iron directly to the leather surface.
