To Buy Thermal Underwear, It Is Necessary To Identify The "Warmth Retention Rate".

Lycra,

Carbon card, heat card, Seville card...

Every time the thermal underwear starts to sell well, all kinds of concepts come to the surface.

But dealers who are shopping are saying that it's not easy for businesses to play gimmicks this year.

Starting from November 1st this year, the new standard of knitted thermal underwear will be implemented in the market.

Under the control of this standard, many of the concept soap bubbles will be returned to their original form, requiring a true indication of the warmth retention rate.

More importantly, with this new industry standard, consumers can only clearly judge the quality of products by looking at the index of "warmth rate".

The market concept is flying everywhere.

On the shelves of shopping malls and supermarkets, the thermal underwear of three *, the south pole, the snow velvet and the North velvet is very beautiful. Besides labeling the cotton, spandex and other raw materials and quality grades on the label, these products are marked with "big name", "Lycra" and "warm card".

But what exactly are these cards?

A consumer of Chen said that when buying, brand names and prices were generally concerned, and these cards were not clear.

Not only did consumers not understand, but also dealers had different opinions.

Some people explain the "warm card" as follows: the scientific name is super fine polypropylene fiber, the name is "warm card" to make it easy for people to accept; while another dealer says the real ingredient should be super fine double acrylic, which can remind people of warm feelings.

Keep warm

Rate is the important index.

In &nbsp2000, the state once issued the "standard of warmed underwear".

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

The Secretary General of Hangzhou Knitting Industry Association says that most of them are warm in view of the current market situation.

Although the manufacturers can meet the old standard requirements, they are not restrained in terms of warmth retention and breathability. This has encouraged the market concept to fly all over the sky.

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, warmth retention rate and unit heat preservation rate. The retention rate should not be less than 30.

For example, if the warmth retention rate of a warm underwear package is 30, the underwear should be able to protect 40 of the heat energy from being lost.
