Production technology of air spinning cotton core filament covering yarn

Abstract

The invention discloses a production technology of air spinning cotton core filament covering yarn.The production technology comprises the following technological steps that 1, core filament fibers are prepared into core filaments through cotton opening and scotching, cotton carding, drawing and doubling and air spinning; 2, outer wrapping fibers are prepared into skin yarn through cotton opening and scotching, cotton carding, drawing and doubling and rough yarn obtaining; 3, the core filaments obtained in the step 1 and the skin yarn obtained in the step 2 are fed into a covering yarn device arranged in ring spun yarn equipment to be prepared into covering yarn; 4, the covering yarn is prepared into the finished air spinning cotton core filament covering yarn through a winding process, wherein cotton fibers are adopted as the core filament fibers.According to the preparation technology of the covering yarn, air spinning cotton yarn is adopted as the core filaments, and therefore the finished yarn is high in hygroscopicity, good in dyeing performance, soft in handfeel, comfortable to wear, simple in appearance, not prone to worm damage, firm and durable; due to the fact that the air spinning yarn is high in fluffy degree, the finished yarn obtained by wrapping the air spinning yarn through ring spinning has the unique style of being soft outside and rigid inside, and a fabric is stiff and smooth and comfortable.

Description

technical field [0001] The invention relates to a weaving process, in particular to a production process of an air spinning cotton core yarn. Background technique [0002] Core-spun yarn, also known as composite yarn or covered yarn, is a new type of yarn composed of two or more fibers. The original core-spun yarn is short fiber and short-fiber core-spun yarn developed with cotton fiber as the skin and polyester spun yarn as the core. In the choice of core wire material, the synthetic filament with better strength and elasticity is used as the core wire in the later development trend. The fineness of the core filament and the number of single filaments in it should be selected according to the fabric application and spinning count. For the core yarn of the same denier, the finer the monofilament, the more the number, the softer and smoother the fabric; on the contrary, the less the number, the better the rigidity and crispness of the fabric. You can also decide whether to ...

Problems solved by technology

The reason why cotton fiber is not used as the core yarn is that it has poor shape retention, low strength, severe wrinkles after washing the cloth surface, and poor wear resistance.
