The hotter the weather, the more people are interested in the coolness The desire will become more intense: whether traveling, at home or sleeping, you want to stay refreshed at all times.
With the increasing demand, various cool and refreshing products have emerged, such as bedding As a result, a “cool-feeling fabric” appeared in the industry, which was widely used in the production of summer quilts and summer mats. The “cool-feeling quilts” and “ice silk mats” produced have also been widely praised in recent years.
So, cool feeling Is the fabric really cool to the touch? Is it an IQ tax product? Today we will talk about what cool-feeling fabrics are and whether cool-feeling quilts are an IQ tax.

What is a cooling fabric?
Cool fabric originated from the United States’ global emerging sports brand, namely “CoolCore” fabric. It uses a unique process to modify or post-process polyester fiber, nylon and other materials to improve its thermal conductivity and moisture absorption and breathability, so that the fabric can quickly diffuse body heat, accelerate perspiration and cooling, and keep dry and comfortable for a long time. .
The so-called “cooling feeling” is strictly speaking “contact instant cooling feeling”. That is, after the fabric comes into contact with the skin, the skin’s heat is transferred to the fabric, and the fabric quickly discharges it. The resulting temperature difference can give people a cool feeling, thus achieving the purpose of cooling. It can be said that the cool feeling of the fabric actually reflects the thermal conductivity of the fabric. The better the thermal conductivity, the stronger the contact cold feeling.

Are cool fabrics an IQ tax?
No. With the development and popularization of cool-feeling fabrics, in order to standardize industry standards and avoid various hype behaviors by merchants, my country also established standards for the performance testing and evaluation of cool-feeling fabrics as early as 2017: GB/T
The document 35263-2017 “Textiles – Testing and Evaluation of Cooling Performance at Instant Contact” clearly states that “the contact cooling coefficient of qualified fabrics shall not be less than 0.15”.
In other words, the cooling fabric has been officially recognized and is not a “selling gimmick” “, “IQ tax”, fabrics that meet the coefficient standards can bring instant cooling on contact.

What other cool fabrics are there?
In the original definition, cool fabrics are modified or post-processed polyester fibers and nylon. However, if the GB/T 35263-2017 “Testing and Evaluation of Cooling Performance of Textiles upon Contact” is used as the evaluation standard, in addition to modified or post-processed polyester fiber and nylon, the following fabrics are also well-deserved “cooling fabrics”
1. Silk fabric
Real silk is silk fiber. Among natural fabrics, silk has the strongest cold feeling on contact (cold feeling coefficient 0.2), so it has a very good moisture absorption and heat conduction effect. While quickly absorbing moisture and wicking away sweat, it will also have a cooling sensation the moment it comes into contact with the skin.

2. Lyocell fiber
Lyocell fiber is the fabric called “Tencel” in the industry , Lyocell fabric feels similar to silk, has a cold feeling coefficient of 0.18, and has a strong cooling feeling on contact. Although the overall performance is weaker than that of silk, compared with pure cotton, Lyocell fiber absorbs��Better breathability, making it more comfortable to use in summer.
