Embodiment 1

[0023] The production technology of embodiment 1 air-spun cotton core silk core-spun yarn, comprises the following processing steps:

[0024] S1: The core fiber is obtained by cleaning, carding, drawing and air spinning;

[0025] S2: Leather yarn is made from outsourcing fibers by cleaning, carding, drawing and roving;

[0026] S3: feeding the core yarn obtained in S1 and the leather yarn obtained in S2 to the core yarn device in the ring spinning equipment to make a core yarn;

[0027] S4: The core-spun yarn is produced through the winding process to obtain the finished air-spun cotton-core staple fiber core-spun yarn.

[0028] The core yarn is fed by the front roller of the spinning equipment and guided into the core yarn device through the active unwinding device, and the leather yarn is fed into the core yarn device after being drafted in the spinning process.

[0029] The fineness of the core yarn obtained by air spinning is 25 English.

[0030] The rotating speed of t...

Embodiment 2

[0036] The difference between embodiment 2 and embodiment 1 is that the fineness of the core yarn obtained by air spinning in embodiment 2 is Ne 23.

[0037] In S1, the rotating speed of the rotor in the process of producing core yarn by air spinning is 8100r / min.

[0038] The process parameters of the spinning process of the core-spun yarn are as follows: the total draft ratio is 40, the draft ratio in the rear area is 1.4, the spindle speed is 14200r / min, the twist is 440TPM, the roller center distance is 55mm and 56mm, and the spacer is 8mm.

[0039] The total draft ratio of leather yarn roving process is 6.4, the rear zone draft ratio is 1.244, the twist coefficient is 110, the dry basis weight is 8g / 10m, and the spindle speed is 760r / min.

[0040] The weight of the core yarn accounts for 50% of the total yarn of the air-spun core yarn cotton staple core yarn.

Embodiment 3

[0042] The difference between embodiment 3 and embodiment 2 is: the fineness of the core yarn obtained by air spinning is 21 Nem.

[0043] In S1, the rotating speed of the rotor in the core yarn production process by air spinning is 8000r / min.

[0044] The process parameters of the spinning process of the core-spun yarn are as follows: the total draft ratio is 37, the draft ratio in the rear area is 1.2, the spindle speed is 14000r / min, the twist is 430TPM, the center distance of the rollers is 51mm and 53mm respectively, and the spacer is 7.5mm.

[0045] The total draft ratio of leather yarn roving process is 6.3, the rear zone draft ratio is 1.242, the twist coefficient is 108, the dry basis weight is 7.5g / 10m, and the spindle speed is 750r / min.

[0046] The weight of the core yarn accounts for 60% of the total yarn of the air-spun core yarn cotton staple core 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 ...
