Industry Standard Of "Knitted Thermal Underwear"

pilling


  


In addition, in order to ensure the wearability of knitted thermal underwear, the standards of pilling, washing size change, stretch elasticity, formaldehyde content and dyeing rate were also specified in the standard.

Among them, pilling, washing size change rate and color fastness are directly perceived by consumers after wearing.

If the pilling index is to evaluate the product after rubbing, the end of the fiber extends out of the surface to form a fluff or small bulge.

The quality of this index is related to cotton quality.

Products made from low cotton or polyester cotton are easy to pilling, and pure cotton products are not easy to pilling.

Washing size change


  


The dimensional change rate of washing provides a method for the determination of dimensional changes of textiles after proper washing and drying.

This program tests the washing temperature at 40 C, which reminds consumers to master the temperature in the process of washing and keeping warm underwear. It is best to wash at 40 C water temperature, otherwise it will cause bad washing results.

color fastness

The color fastness test is a comprehensive evaluation of the degree of discoloration of textiles from 3 aspects: acid proof liquid, alkali resistant liquid and rubbing.

Low color fastness and serious fading of products.

Formaldehyde content


  


Formaldehyde content is also marked in strict requirements for formaldehyde content.

According to analysis, formaldehyde is commonly found in some finishing agents, while knitted thermal underwear has some adhesives in the processing process, which is also one of the factors leading to formaldehyde.

After a lot of tests, we finally set the formaldehyde content index to less than 50mg/kg.
