Problems solved by technology

[0002] With the progress of society and the continuous improvement of living standards, people have higher and higher requirements for clothing diversification, and the updating speed of clothes is getting faster and faster. The discarded knitted clothes cannot be used in the most reasonable way, resulting in waste.
Knitted fabrics placed for too long will also seriously affect their drape and crispness. Most people will disassemble and reuse the long-standing fabrics, but the comfort of new products will be greatly reduced compared with the previous ones.

Embodiment 1

[0013] A treatment method for making waste knitted fabrics reusable, comprising the following steps: 1) cleaning of waste knitted fabrics; specifically, putting waste knitted fabrics into a bath liquid with a pH value of 6 and a bath ratio of 1:15, Soak at 50°C for 20 minutes, bake for 20 minutes, and dry for 10 minutes; 2) Pretreatment: Singeing the washed knitted fabric with a winding speed of 500m / min and a flame temperature of 900°C; 3) Decolorization and whitening Be that the methanol of 35% and the glacial acetic acid of 10% by mass concentration are mixed in equal proportions to form a mixture, and the knitted fabric after singeing is put into the mixture at normal temperature, the temperature rises to 50° C., and stands for 10- After 20 minutes, the temperature was lowered to normal temperature; 4) antibacterial treatment; the silver ion antibacterial agent was wrapped into a microparticle antibacterial gel, and the prepared antibacterial gel was sprayed on the surface ...

Embodiment 2

[0015] A treatment method for making waste knitted fabrics reusable, comprising the following steps: 1) cleaning of waste knitted fabrics; specifically, putting waste knitted fabrics into a bath liquid with a pH value of 7 and a bath ratio of 1:20, Soak at 60°C for 20 minutes, bake for 30 minutes, and dry for 20 minutes; 2) Pretreatment: Singeing the washed knitted fabric with a winding speed of 700m / min and a flame temperature of 1000°C; 3) Decolorization and whitening ; Mix methanol with a mass concentration of 35% and glacial acetic acid with a mass concentration of 10% in equal proportions to form a mixture, put the singeed knitted fabric into the mixture at room temperature, raise the temperature to 50°C, and let it stand for 20 minutes , lower the temperature to normal temperature; 4) antibacterial treatment; wrap the silver ion antibacterial agent into a microparticle antibacterial gel, and spray the prepared antibacterial gel on the surface of the knitted fabric after s...

Embodiment 3

[0017] A treatment method for making waste knitted fabrics reusable, comprising the following steps: 1) cleaning of waste knitted fabrics; specifically, putting waste knitted fabrics into a bath liquid with a pH value of 6.5 and a liquor ratio of 1:18, Soak at 58°C for 20 minutes, bake for 28 minutes, and dry for 15 minutes; 2) Pretreatment: Singeing the washed knitted fabric with a winding speed of 600m / min and a flame temperature of 950°C; 3) Decolorization and whitening Be that the methanol of 35% and the glacial acetic acid of 10% by mass concentration are mixed in equal proportions to form a mixture, and the knitted fabric after singeing is put into the mixture at normal temperature, the temperature rises to 50° C., and stands for 10- After 20 minutes, the temperature was lowered to normal temperature; 4) antibacterial treatment; the silver ion antibacterial agent was wrapped into a microparticle antibacterial gel, and the prepared antibacterial gel was sprayed on the surf...

Abstract

The invention discloses a treatment method for reusing waste knitting fabric. The treatment method includes steps of 1) washing of the waste knitting fabric; 2) pretreatment; 3) decolorizing and bleaching; 4) sterilization; 5) after treatment. The treatment method solves the problem that the waste knitting fabric cannot be reused reasonably, comfort level of the retreated fabric can be the same as usual, waste of the waste knitting fabric is avoided and resource is saved.

Description

technical field [0001] The invention relates to a method for finishing fabrics, in particular to a treatment method for making waste knitted fabrics reusable. Background technique [0002] With the progress of society and the continuous improvement of living standards, people's requirements for clothing diversification are getting higher and higher, and the updating speed of clothes is getting faster and faster. The discarded knitted clothes cannot be used in the most reasonable way, resulting in waste. Knitted fabrics placed for too long will also seriously affect their drape and crispness. Most people will disassemble and reuse the long-standing fabrics, but the comfort of new products will be greatly reduced compared with the previous ones. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to provide a treatment method for making waste knitted fabrics reusable in order to make up for the deficiencies of the prior art. ...
