A kind of Sirofill core-spun yarn production device and production method

Abstract

The invention provides a Sirofil core-spun yarn production device and production method. The device comprises a cradle rod connected with transverse supports, the transverse supports comprise the back transverse support, the middle transverse support and the front transverse support which are each additionally provided with left godet wheels and right godet wheels, middle godet wheels are connected between the left godet wheels and the right godet wheels of the front transverse support, and a left godet groove, a middle godet groove and a right godet groove are formed in the middle of the surface circumference of each middle godet wheel. During yarn spinning, a filament is fed into a front roller through the godet wheels in an S-shaped route, single core yarn is fed from the position over covering yarn and the position between the covering yarn and the filament, the core yarn is covered with the covering yarn, then the covering yarn and the filament are wrapped into yarn, or the core yarn is covered with both the covering yarn and the filament to be wrapped into the yarn, and then production of Sirofil core-spun yarn with an excellent core yarn covering effect and an excellent taking effect is achieved.

Description

technical field [0001] The invention relates to the new technical field of ring spinning, in particular to a production device and a production method of a serofil core-spun yarn. Background technique [0002] Core-spun yarn refers to a composite yarn combined by core yarn and sheath yarn. Generally, the filament is used as the core yarn, and the staple fiber is the outer fiber (sheath yarn). Its characteristic is that through the combination of the outer fiber and the core yarn, it can play Their respective advantages make up for the deficiencies of both parties, maximize their strengths and avoid their weaknesses, and optimize the structure and characteristics of the yarn. The production of core-spun yarn has a history of more than 40 years. The demand for products is constantly increasing, and the varieties of related yarns are also constantly enriched. At present, there are more than 10 million spindles of core-spun yarn in the world, and it is expected to increase at a...
