In the fall and winter season, as a matching outfit for skirts, wool trousers and cashmere blended trousers are increasingly favored by Ms. Aimei in the city and become a market selling product.

In order to make the consumers objectively understand the quality of the market wool trousers and cashmere blended trousers, the China Consumers’ Association conducted comparative tests on such products on the market, and the test of comparative tests entrusted the China Business Confederation to s Inspection and Testing Center (Tianjin) completed.

Sample conditions

The samples of this comparative test were purchased from 20 large and medium sized shopping malls and supermarkets in Beijing and Tianjin by a staff member who simulated consumer identities. A total of 41 samples were obtained, including 29 brands of wool trousers samples and 12 samples of cashmere-blend trousers. Brands. Origins include Beijing, Tianjin, Shanghai, Hebei, Inner Mongolia, Liaoning, Jiangsu, Zhejiang, Shandong, Guangdong, Xinjiang, Taiwan (supervising) and other 12 regions, basically including wool trousers and cashmere sold in the markets of Beijing and Tianjin. The main brand of blended pants, has a certain representative.

Analysis of test results

1. Product identification and wool and cashmere content: According to the stipulations of GB5296.4-1998 "Consumer Products Instructions for Use of Textiles and Garments", the manufacturer must indicate the name of the raw material used in the product and its content. The labeling of the fiber content should be in accordance with FZ/T01053-1998 "Identification of textile fiber content".

After testing, the fiber components or content of the 14 sample labels in the 29 wool trousers samples do not match the measured results. In the 12 cashmere blended trousers samples, the fiber composition or content of 11 samples is not consistent with the measured value.

The inconsistency between the fiber composition and the measured results is indicated by the fact that the type of fiber is mislabeled or not marked with fiber-labeled wool, such as nylon being marked as polyester, and wool being referred to as sheep cashmere (this name is not defined in national standards), The nylon or polyamido core-spun silk fibers are collectively referred to as spandex, and the chemical fibers enclosing the spandex are negligible, and other chemical fibers act as cashmere fibers or wool fibers.

The level of wool and cashmere in wool trousers and cashmere blended pants is a concern for the majority of buyers. The gap between the content and the marked value has become the most prominent aspect of this test. After testing, 29 woollen trousers samples have The difference between the wool content and the label value of the four samples is larger, with the lowest difference being 14.6% and the highest difference being 44.5%. If the “Good Cat” brand wool trousers (100cm), the marked wool content is 80%, and the measured value is only 35.5%. The cashmere content of cashmere blended trousers samples was inconsistent with the marked value. In the 12 cashmere blended trousers samples, there were 10 samples with far-distant difference between the measured value and the marked value of cashmere. The lowest difference was 14.1%, and the highest difference was 76.8%. "Mandula" brand women's seamless cashmere blended pants (100cm), marked with 80% cashmere, the measured value of 3.2%; "macro leopard" 34101 cashmere pants (105cm), marked 95% cashmere, measured value 34.1%; "Cashmere" brand L003 female twisted trousers (115cm), marked 60% cashmere content, measured cashmere does not exist; "Day bath" brand high elastic female pants (100cm), marked 30% cashmere content, measured Does not contain cashmere.

2. Pilling: This indicator is one of the important indicators for assessing the quality of wool and cashmere products. Pilling indicators are divided into five grades of nine (a half grade), the higher the grade, the better. The pilling index is lower than 3 It will affect the wear and appearance.

In the comparative trials of wool trousers samples, there were 22 brands with a pilling index of grade 3 and above, of which 7 samples had a good pilling index of 4. There were 7 samples with a pilling index lower than 3, May affect the wear and appearance.

For cashmere blended trousers samples, there were 2 samples with a pilling index lower than 3, 6 samples with a pilling index of 4 and 4 samples with a pilling index of 3.

3. Breaking strength: This index is an indicator for assessing the fastness of wool and cashmere products. According to the standards, the top break strength index of wool trousers (combed) is not less than 323 kPa. Cashmere blended trousers (comb ) First-class product's bursting strength index is not less than 196kPa. The comparative test samples are all higher than the standard, in which the highest value of wool pants top breaking strength is "Heng Yuan Xiang", and the highest burst strength index of cashmere blended pants is "Ya Bao Sidi."

4. Washing size change rate: According to the FZ/T73018-2002 "Wool Knitwear" product standard, wool pants assessment of the total size change rate, washing program 2 × 7A, assessment indicators for the length -5%, width +5%; According to The FZ/T73009-1997 "Cashmere Knitwear" product standard stipulates that the cashmere blended trousers should be tested for slack shrinkage, and the washing procedure should be 1 × 7A. The assessment index is ±5% for length contraction and ± 5% for width contraction.

The sample size change rate of water washing is better, all higher than the standard.

5. Tensile elasticity (elongation, non-renewable elongation): This index is to evaluate the elongation of the wool knitted fabric under low load and the residual deformation at the end of the load. The elongation refers to the sample at 12.25. The ratio of the length of the sample under the N load and the original mark length of the sample to the length of the original mark of the sample. The non-recoverable elongation refers to the length of the sample taken after being stretched for three times and returned flatly after 30 minutes. The difference between the length of the original mark of the sample and the length of the original mark of the sample. Among them, the greater the elongation, the better the elasticity of the fabric, and the smaller the non-recoverable elongation, the better the recovery of the fabric. Elongation and non-recoverable elongation indicators comprehensive assessment of the fabric tensile elasticity index.

In this comparative sample of woollen trousers, the highest value of tensile elongation was 132.9% and the lowest was 41.9%; the highest value of longitudinal non-recoverable elongation was 5.7%, and the lowest was 0. The maximum value of the horizontal elongation of the indicator is 274.3%, the lowest value is 97.0%; the highest value of the horizontal non-recoverable elongation is 15.6%, the lowest value is 0.4%. The brand with better comprehensive index has Ordos Aoqun brand 2K003 seamless Women's trousers, spring bamboo brand WP812074 low waist seamless stretch pants, Ruikai H8007—1 Mercerized ultra-fine elastic trousers.

In the sample of cashmere blended pants, the highest value of longitudinal elongation was 120.8%, the lowest value was 55.2%, the highest value of longitudinal non-recoverable elongation was 8.0%, the lowest value was 1.7%, and the highest value of transverse elongation was 181.8. %, the lowest value is 71.8%; the highest value of transverse non-recoverable elongation is 24.9%, the lowest value is 1.3%.

6. Insulation rate: This indicator is the index of the thermal properties of the test fabric, which refers to the percentage of the difference between the heat dissipation when there is no sample and the heat dissipation when there is no sample and the heat dissipation when there is no sample.

The highest heat preservation rate for the woollen trousers samples tested was "Hao Gui Shi Jia" brand 699A shrink-wool blended ultra-thin cropped trousers with a measured value of 34.4%.
