Nylon stretch yarn has gloss differences, commonly referred to as high gloss, semi matte, and fully matte.

English full name:

Semi dull nylon: Semi dull nylon

English abbreviation:

Half light: SD extinction: FD light: BR

Half light is half extinction, which means extinction eliminates a slight luster. Extinction is complete extinction, without luster, also known as sub light.

According to the different content of titanium dioxide as a matting agent in polyester chips, chips are generally divided into bright, semi dull, and fully dull types. The mass fraction of titanium dioxide in the bright light slice is 0%, and the mass fraction of titanium dioxide in the semi extinction slice is 0% 30% ± 0 . 0.5%, with a mass fraction of up to 2% titanium dioxide in fully extinguished slices 5% ±0 . 1%. The main difference between semi extinction slices and fully extinction slices is the difference in titanium dioxide content, with the latter being more than 8 times higher than the former. Fully matte polyester chips are a high value-added product in the domestic polyester market. Fully matte chips not only reduce the reflection and flicker of fibers, but also give subsequent fibers a soft luster, good deep dyeing ability, high fabric drape, and strong covering function, which can meet the needs of producing high-end clothing.
