Starting in November 1st this year,

It will be implemented in the market.

The new standard has targeted the index of warmth retention.

According to the new standard, the main functional indicators of thermal underwear should be clearly identified on product packaging, that is, the rate of warmth retention and the unit heat preservation rate.

With this new industry standard, consumers can clearly judge the quality of products by looking at the index of "warmth retention".

Reporters access to relevant information learned that, as early as 2000, the state has introduced "floc type knitting."

Standard.

However, since 2001, most manufacturers no longer use the floc layer made of wool or chemical fiber, instead of the fibers with better thermal insulation or the process of raising and raising, which results in the relevant indexes in the old standard.
