Problems solved by technology

[0002] Generally, the non-glue cotton is formed by stacking multiple layers in the continuous production process. In the multi-layer overlapping, there will be quality problems such as gaps in the joints and overlapping of the ends of the mesh. These problems cause the thickness of the non-glue cotton to be uneven, and there are obvious Quality problems such as gaps between joints and overlapping of laps, etc., when used by garment factories, it is easy to cause waste and increase the consumption of non-glued cotton. Even if all these materials are barely used in clothing, it still gives people a sense of no high-end. How to solve these quality problems The problem is a technical problem in this field

Embodiment 1

[0012] The preparation method of the light and thin non-glued cotton of this embodiment sequentially includes: material selection, opening, carding, oven baking, and molding and packaging.

[0013] Select 70wt% of polyester staple fiber and 30wt% of low-melting point fiber for batching, and then mix by multi-layer tiling method to mix and disperse different fibers; then send the mixed batching into the opener for opening, opening During the loosening process, the fibers are fully mixed and sent to the cotton box for storage after opening; then the opened fibers are fed from the cotton box to the carding machine for carding, and the feeding amount is controlled according to the product gram weight during carding, and Set the speed of the wool transmission chain to 8 m / min, and the frequency of reverse wool: 12 times / min, and the material is automatically fed through the cotton box, which is more conducive to mixing evenly and combing; then the carded fibers are laid directly thr...

Embodiment 2

[0015] The preparation method of the light and thin non-glued cotton of this embodiment sequentially includes: material selection, opening, carding, oven baking, and molding and packaging.

[0016] Select 80wt% of polyester staple fiber and 20wt% of low-melting point fiber for batching, and then mix by multi-layer laying method to mix and disperse different fibers; then send the mixed batching into the opener for opening, opening During the loosening process, the fibers are fully mixed and sent to the cotton box for storage after opening; then the opened fibers are fed from the cotton box to the carding machine for carding, and the feeding amount is controlled according to the product gram weight during carding, and Set the speed of the wool transmission chain to 15 m / min, and the frequency of reverse wool: 20 times / min, automatically feeding through the cotton box, which is more conducive to mixing evenly and combing; then the carded fibers are laid directly through the bridge...

Embodiment 3

[0018] The preparation method of the light and thin non-glued cotton of this embodiment sequentially includes: material selection, opening, carding, oven baking, and molding and packaging.

[0019] Select 90wt% of polyester staple fiber and 10wt% of low-melting point fiber for batching, and then mix by multi-layer tiling method to mix and disperse different fibers; then send the mixed batching into the opener for opening, opening During the loosening process, the fibers are fully mixed, and then sent to the cotton box for storage after opening; then the opened fibers are fed from the cotton box to the carding machine for carding. Set the speed of the wool transmission chain to 20 m / min, and the frequency of reverse wool: 25 times / min, automatically feeding through the cotton box, which is more conducive to mixing evenly and combing; then the carded fibers are laid directly through the bridge at one time The net enters the oven to bake, the temperature is 180 ℃, and the drying ...

Abstract

The invention relates to a preparation method for light non-glue cotton. The preparation method sequentially comprises the steps of material selection, opening, cotton carding, oven drying and forming and packing. In the step of cotton carding, feed quantity is controlled according to product gram weight requirements. The speed of a hairy transmission chain is 6m / min to 20m / min. The reverse combing frequency is 10 times per minute to 25 times per minute and fiber is formed by combing for once. The combed fiber is directly laid in a net through a passing bridge and enters an oven to be dried. The temperature is 160 DEG C to 180 DEG C and drying time in the oven is 10 seconds to 25 seconds. The non-glue cotton produced through the method can guarantee and highlight excellent performance of the non-glue cotton. Net cotton does not need to be overlapped for a plurality of layers in the process of production, the cotton can be formed by combing for once, production efficiency is improved, cost is saved based on a prior foundation and the produced non-glue cotton is free of quality problems of uneven thickness such as connector gaps and lap head overlap and is high in quality.

Description

technical field [0001] The invention relates to the field of preparation of non-glue cotton, in particular to a preparation method of light and thin (20g / ㎡-200g / ㎡) non-glue cotton. Background technique [0002] Generally, the non-glue cotton is formed by stacking multiple layers in the continuous production process. In the multi-layer overlapping, there will be quality problems such as gaps in the joints and overlapping of the ends of the mesh. These problems cause the thickness of the non-glue cotton to be uneven, and there are obvious Quality problems such as gaps between joints and overlapping of laps, etc., when used by garment factories, it is easy to cause waste and increase the consumption of non-glued cotton. Even if all these materials are barely used in clothing, it still gives people a sense of no high-end. How to solve these quality problems The problem is a technical problem in the art. Contents of the invention [0003] The technical problem to be solved by ...
