Most of the underwear is fiber.

According to the circular, 57 knitted underwear products produced by 33 enterprises in Guangzhou were selected for spot checks.

Of the 20 batches of substandard products, 17 batches were due to unqualified fiber components.

The main reason for the failure is that the quality consciousness of the enterprises is weak, and the raw materials for purchase are not strictly controlled.

Guangzhou Quality Supervision Bureau reminds consumers that when choosing underwear products, besides carefully checking the instructions and labels of the products, they should also check the symmetry of the parts of the product, whether the stitches are round, straight or straight, and there is no wrinkle phenomenon.

If there is a needle hole in the stitch, because of the strong dispersion of knitwear, once the needle hole appears, it will soon form a hole and affect the use of the product.

The main reason for disqualification may be that the enterprises often carry out post-processing of the products in alkaline conditions or alkaline finishing agents in the process of production. If they are not strictly neutralized or neutralized according to the technological conditions, they may cause the pH value to exceed the standard range.

In the aspect of water washing size change rate (also called shrinkage rate), 1 batches of products were not qualified for the spot check, which was a colorful seasonal quilt cover, pillowcase and bed cap for Guangzhou Wei Shang Textile Co., Ltd.

The size change rate of washing is not qualified, which will lead to a bigger change in the size of bedding after washing, which will affect the appearance and use of bedding.

Fiber type, fabric density, yarn branch density, post processing technology (such as pre shrinking process are not in place) are the main factors affecting the size change rate of fabric washing.

The Quality Supervision Bureau recommends that consumers choose to purchase some products and labels when trying to buy the products mentioned above. Besides, they can try to buy some large manufacturers and famous brand products, and at the same time, they can select products that meet the requirements by looking at the appearance, technology, smell and color.
