Embodiment 1

[0025] A processing method for low noil on a cotton spinning comber, achieved through the following steps:

[0026] (1) On the pre-draw frame in the combing preparation process, increase the number of fed slivers, increase the total draft multiple and the rear zone draft multiple.

[0027] The feeding number of sliver on the pre-draw frame is changed from 5-6 to 7-8, the total draft ratio is changed from 4-6 times to 7-8 times, and the draft ratio in the rear area is changed from the original Adjust the 1.6-1.8 times to 1.8-2.1 times, so as to improve the fiber structure such as fiber straightness, parallelism and separation degree of pre-drawing.

[0028] (2) On the sliver doubling machine in the combing preparation process, increase the number of slivers to be combined and increase the total draft multiple.

[0029] The combined number of slivers on the sliver doubling machine is adjusted from 20-24 to 24-32, and the total draft ratio is adjusted from 1.4-1.7 to 1.6-2.4.

Embodiment 2

[0043] Taking the raw cotton with an average grade of 3.8, a hand-pulled fiber length of 25mm, and a micronaire value of 3.6, as an example to spin a 12-count pure cotton combed yarn, a process for low noil on a cotton combing machine is described in detail. Method implementation method:

[0044] (1) On the pre-draw frame of the combing preparation process, 8 cotton slivers are merged. The total draft ratio of the draw frame is set to 8 times, and the draft ratio in the rear area is set to 2.1 times.

[0045] (2) On the sliver doubling machine, the number of slivers combined is 32, and the total draft ratio is 2.4 times.

[0046] (3) On the combing machine in the combing process, the quantitative setting of the cotton lap fed to the combing machine is set to 75 g / m, and the cotton feeding length of each working cycle of the combing machine is set to 5.9 mm.

[0047] (4) Set the cotton feeding mechanism of the combing machine to the forward feeding mode, and adjust the positio...

Abstract

The invention discloses a low-cotton-droppings processing technology for a cotton spinning combing machine. The technology comprises the steps: on a pre-drawing frame of a combing preparation procedure, increasing the number of cotton slivers fed, and increasing total draft multiple and rear area draft multiple; on a ribbon lap machine of the combing preparation procedure, increasing the number of cotton slivers combined, and increasing the total draft multiple; on the combing machine of a combing procedure, determining the cotton roll fixed quantity and cotton feeding length of the combing machine; adopting a forward cotton feeding manner, and forwards moving a cotton feeding roller; improving a clamping plate transmission system of the combing machine; reducing cotton droppings spacing; reducing the total tooth number of a cylinder and increasing carding spacing; reducing the carding strength and insertion depth of a top comb. According to the technology, the probability that fibers are grabbed by pin teeth of the cylinder during carding is lowered, and the aim of low cotton droppings during combing is realized, so that the cotton droppings ratio of combing is lowered to 4-8%, the requirements of semi-combed yarn, of which the combed yarn is relatively thick and the quality requirements are relatively low, on low cotton droppings are met, and the aims of reducing cotton consumption cost and increasing spinning economic benefit are achieved.

Description

technical field [0001] The invention relates to the technical field of cotton spinning combing processing, in particular to a processing method for cotton spinning combing machines to reduce noil. Background technique [0002] The main task of the combing process is to remove the short staples, neps and impurities in the lap, and to make the fibers straight, parallel and separated. Therefore, noil will inevitably be generated during the combing process. The amount of noil in the combing process can be expressed by the combing noil rate, which refers to the percentage of the ratio of the falling amount of cotton fibers to the feeding amount during the processing of the combing machine. The higher the combed noil rate, the greater the amount of cotton used to spin 1 ton of combed yarn, and the higher the spinning cost. Therefore, the level of combed noil rate directly affects the economic benefits of spinning enterprises. At present, during the combing process of cotton spinn...
