Problems solved by technology

The defect of the first production process is that the strength and density of needle punching are high, and the tensile force of the flakes produced is good but the elasticity is poor. For the flakes produced by the two processes, if there is less glue spraying, the flakes produced will have good elasticity but poor tensile force; If the temperature of the flake oven is high, the flakes produced will turn yellow in color, stiffen and have poor elasticity. If the temperature of the oven is low, the flakes produced will have better elasticity and poor pulling force.
The above three processes are difficult to produce ideal flake products

Embodiment 1

[0022] In embodiment 1, a kind of production technology of tensile high elastic cashmere floc, comprises the following steps:

[0023] S1 ingredients: Weigh according to the mass ratio of substances, weigh 5kg of low melting point fiber and 1kg of cashmere and record it as group A ingredients; weigh 80kg of cashmere and 4kg of three-dimensional hollow elastic fiber and record it as group B ingredients;

[0024] S2 Mixing: Mix the ingredients of group A through the mixer and wool machine twice to achieve uniform mixing. After mixing, send them to the cotton box of group A by the opening machine of group A for standby. The ingredients of group B are also passed through the mixer, The kneading machine is carried out twice to achieve uniform mixing, and after mixing, it is sent to the B group cotton box by the B group opener for standby;

[0025] S3 carding: use the carding production line of group A to card the raw materials in the cotton boxes of group A to produce two layers of...

Embodiment 2

[0034] In Example 2, compared with Example 1, Group A ingredients include 8 kg of low-melting fiber and 4 kg of cashmere, Group B ingredients include 90 kg of cashmere, 8 kg of three-dimensional hollow elastic fiber, and other operating steps are the same as in Example 1.

Embodiment 3

[0035] In Example 3, compared with Example 1, Group A ingredients include 7kg of low-melting fiber and 2kg of cashmere, Group B of ingredients include 85kg of cashmere, 6kg of three-dimensional hollow elastic fiber, and other operating steps are the same as Example 1.

[0036] Among the examples 1-3, the tensile strength of the cashmere flakes produced by the technical process of the present invention is significantly improved, and the plush on the surface of the cashmere flakes is fixed by the melt-bonded low-melting-point fibers, so that the plush fibers are not easily It falls off, and the surface of the alpaca flakes is smooth and flat, which greatly increases the pulling force of the camel hair flakes. The product is three times that of the original traditional flakes tested by the China Textile Products Quality Inspection and Inspection Center; the elasticity of the flakes has also been significantly improved. Improvement, the upper and lower layers of low-melting-point f...

Abstract

The invention relates to the technical field of cashmere wool production, in particular to a production process of tensile high-elasticity cashmere wool flakes. The production process comprises the following steps: S1 compounding; S2 mixing; S3 carding; S4 fusion bonding; and S5 needling. The appearance quality of the flakes is also significantly improved, mainly including smooth and flat surfacesof the flakes, non-sticky and lint-free flakes and improved aesthetic appearance of the flakes. The tensile strength of the cashmere wool flakes produced by the technical process disclosed by the invention is significantly improved. The product is tested by the China Textile Products Quality Inspection and Inspection Center that the quality is three times that of original traditional flakes; theelasticity of the flakes is also significantly improved; and the elasticity of the flakes is tested by the National Textile Products Testing and Inspection Center, showing that the compressive elasticity of the flakes is twice that of a product produced by a traditional process.

Description

technical field [0001] The invention relates to the technical field of cashmere wool production, in particular to a production process for stretch-resistant and highly elastic cashmere wool flakes. Background technique [0002] At present, in the production process of cashmere wool flakes in the market, three production modes are mostly used. One is: a carding machine and a net laying machine, and then the acupuncture machine is used to produce needled flakes. The second is: carding and laying After the net is sprayed with glue, it is called glue-sprayed flakes. The third is: the flakes produced by a constant temperature oven after carding and laying are called baked flakes. The defect of the first production process is that the strength and density of needle punching are high, and the tensile force of the flakes produced is good but the elasticity is poor. For the flakes produced by the two processes, if there is less glue spraying, the flakes produced will have good elast...
