YIROU-SPUN LONG-STAPLE COTTON NYLON WOOL HIGH-STRENGTH COVERING YARN

News 1030

Key words: high-strength, anti-piling, Yirou spinning technology

Raw materials and specifications:

Ring-spinning long-staple cotton/nylon filament/wool 38/37/25 20~50s

Reasons for recommendation: Yirou-spinning is an upgraded version

of what is called the new type of spinning technology (Ruyi spinning) in

embedded systems, and it is a compound processing technology to use two filaments and staple for combination, improving yarn’s strength, able to adjust filament and staple materials as well as the feeding method according to product requirements. FDY’s special shrinking quality enables textiles to have a certain expansion and elasticity, so that the product has a shiny and clean surface, effectively prevents pilingpilling, endures wear, and produces a body-shaping effect. At present, it is mostly used in the military field, and is expected

to see wider applications in civil and outdoor fields.

Scope of application: Clothing
