Abstract

The invention discloses a preparation method of variable-twist Sorona filament and Richcel staple fiber yarn coated fancy yarn. Richcel staple fiber yarn coats the surface of Sorona filament through a hollow spindle coating and twisting device; during coating and twisting, the Sorona filament is fed into a hollow spindle through a front roller; and the speed of the front roller is not changed, the rotating speed of the hollow spindle periodically changes within a certain spinning length, and the periodic change rule is defined in the description, wherein v refers to the rotating speed of the hollow spindle, one period of the length change of the yarn is L1+L2+L3, L1, L2 and L3 are the lengths of different sections in one period respectively, and L is the length position of the yarn in one period. According to the preparation method of the variable-twist Sorona filament and Richcel staple fiber yarn coated fancy yarn, the different yarn sections of the spun fancy yarn are different in twist, so that the elasticity and elastic resilience of the different yarn sections are different, and the elasticity and elastic resilience of different parts of a woven fabric are different; and the fancy yarn can be widely applied to the field of sportswear and other fabrics.

Description

technical field [0001] The invention belongs to the technical field of spinning, and relates to a spinning method for fancy yarns, in particular to a spinning method for twist-variable fancy yarns coated with Sorona filaments and Lisa staple fibers. Background technique [0002] Sorona fiber is polymerized from two polymers, PDO and PTA. Compared with nylon 6, its production process reduces energy consumption by 30% and reduces greenhouse gas emissions by 60%. Sorona fiber can endow the fabric with excellent properties such as excellent stretch recovery performance, super soft hand feeling, good shape retention and bright color. The current research on Sorona fiber is mainly to blend it with wool or other fibers or apply monofilament to knitted fabrics, and there are fewer studies on its filament composite yarn or fancy yarn. Lisa fiber is a strong bio-based cellulose fiber, which is environmentally friendly and degradable. It has excellent properties such as spinnability, ...
