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 Example 1, a production process of a tensile high elasticity cashmere wool flock includes the following steps:

[0023] S1 Ingredients: Weigh according to the mass ratio of the material, weigh 5kg of low-melting 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: The A group of ingredients are passed through the mixer and the wool machine twice to achieve uniform mixing. After mixing, the A group opener is sent to the group A cotton box for standby, and the group B ingredients are also passed through the mixer, The knitting machine is carried out twice to achieve uniform mixing. After mixing, it is sent to the cotton box of group B by the opener of group B for standby;

[0025] S3 carding: Use the group A carding production line to comb the raw materials in the cotton box of group A to produce two layers of netting; use the carding p...

Embodiment 2

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

Embodiment 3

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

[0036] In Examples 1-3, the tensile strength of the cashmere flakes produced by the technical process of the present invention is significantly improved. The plush on the surface of the cashmere flock is fixed by melt-bonded low-melting fibers, making the fleece fibers difficult It also makes the surface of the alpaca flock smooth and flat, which greatly increases the tension of the camel flock. The product has been tested by the China Textile Products Quality Inspection Center to be 3 times the original traditional flock; the elasticity of the flock is also obvious Under the action of the needle punching machine, the upper and lower layers of low-melting-point fibers uniformly bring the ...

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 of a tensile-resistant and highly elastic cashmere wool flake. Background technique [0002] At present, in the production process of cashmere wool flakes in the market, three production modes are used. One is: a carding machine and a netting machine are then passed through the needle punching machine to produce needle-punched flakes. The second is: carding and paving. The glue-spraying flakes after the netting process are called glue-spraying flakes. The third is: the flakes produced in a constant temperature oven after carding and laying are called baking flakes. The defect of the first production process is that the strength and density of needle punching is high, and the produced flakes have good tension but poor elasticity. On the contrary, the density of needle punching is low, and the strength is low, and the produced flakes have poor tensi...
