Relevant standards for bedding appraisal

As a part of home textile products, bedding is an indispensable daily necessity in people's lives. In recent years, the production of bedding products has developed rapidly, and the series of products of various patterns, styles and fabrics can be described as dazzling. Bedding includes textile products such as bed sheets, quilt covers, pillowcases, bed covers, quilts, pillows, cushions, etc. In general, the criteria for identifying bedding can be divided into the following 7 methods:

1. Fiber content. The fiber content determines the cost and performance of the product and the comfort during use.

2. Dimensional change rate of water washing. The shrinkage problem of bedding during use has always been a concern of consumers, mainly manifested in poor dimensional stability, deformation after washing, and smaller size, which affects the use and aesthetics.

3. Decompose aromatic amines. Some azo dyes are in long-term contact with human skin, decompose and reduce under special conditions, and release some carcinogenic aromatic amines, which become the inducing factor of human disease and have potential carcinogenicity.

4. Color fastness. Color fastness refers to the fastness of the product to perspiration, washing and rubbing. The color fastness is good or bad, which directly affects the health and safety of the human body and the appearance of the product. Bedclothes with poor color fastness will cause the pigment on the fabric to fall off and fade when they are exposed to sweat during use, and the dye molecules in them may be absorbed by the body through the skin and endanger human health.

5. PH value. Textiles with excessive PH value will destroy the balance mechanism of human skin, stimulate the human skin, reduce the ability of the human body to resist external bacteria, produce symptoms such as allergies and rashes, and endanger human health.

6. Formaldehyde content. Formaldehyde is a toxic substance present in textile fabric finishing agents. After being absorbed by the body, it has a strong stimulating effect on the skin and respiratory tract, which can cause dermatitis and inflammation of the respiratory tract mucosa.

7. Breaking strength. If the breaking strength is too low, it will directly affect the service life of the product.

As a daily necessity that has been in direct contact with people for a long time, the quality of bedding directly affects people's health. Understanding the relevant knowledge in many ways can avoid bringing unhealthy factors home.
