Embodiment 1

[0013] A finishing process for wool knitted fabrics, comprising washing shrinkage treatment, softening treatment and drying treatment, the specific steps are as follows:

[0014] (1) Washing shrinkage treatment: choose the washing shrinkage agent KJF-10A of 3-5% of the weight of the fabric, stir the washing shrinkage agent evenly with 25°C warm water, add it to the working solution at 38°C, soak for 15min, and then wash, the time 20min;

[0015] (2) Softening treatment: in warm water at 19°C, using a bath ratio of 1:30, using 2% of the fabric weight softening and smoothing agent A80, soaking for 20 minutes, and then dehydrating, the dehydrating time is 5 minutes;

[0016] (3) Drying treatment: Dry at a temperature of 50°C for 30 minutes.

Embodiment 2

[0018] A finishing process for wool knitted fabrics, comprising washing shrinkage treatment, softening treatment and drying treatment, the specific steps are as follows:

[0019] (1) Shrinkage treatment: select the shrinkage agent KJF-10A of 5% of the fabric weight, stir the shrinkage agent evenly with warm water at 25°C, add it to the working solution at 40°C, soak for 20 minutes, and then wash for 25 minutes ;

[0020] (2) Softening treatment: in warm water at 25°C, using a bath ratio of 1:40, using 4% of the fabric weight softening and smoothing agent A80, soaking for 30 minutes, and then dehydrating, the dehydrating time is 6 minutes;

[0021] (3) Drying treatment: dry at a temperature of 65°C for 40 minutes.

Embodiment 3

[0023] A finishing process for wool knitted fabrics, comprising washing shrinkage treatment, softening treatment and drying treatment, the specific steps are as follows:

[0024] (1) Shrinkage treatment: select the shrinkage agent KJF-10A of 4% of the weight of the fabric, stir the shrinkage agent evenly with warm water at 25°C, add it to the working solution at 39°C, soak for 17 minutes, and then wash for 22 minutes ;

[0025] (2) Softening treatment: In warm water at 22°C, use a bath ratio of 1:35, select 3% of the fabric weight softening and smoothing agent A80, soak for 25 minutes, and then dehydrate for 5 minutes;

[0026] (3) Drying treatment: Dry at a temperature of 55°C for 35 minutes.

[0027] In the present invention, by adjusting the components of the detergent, the detergent still has the activity at a high temperature at a low temperature, thus ensuring that the washing effect of the detergent at a low temperature is unchanged or even better, and at the same time...

Abstract

The invention discloses an after finishing technology of a woolen knitted fabric. The technology comprises washing shrinkage treatment, softening treatment and drying treatment. The washing shrinkage treatment comprises the steps of selecting washing shrinkage agent KJF-10A which accounts for 3%-5% of the weight of a fabric, using warm water to stir the washing shrinkage agent evenly, adding the washing shrinkage agent into working liquid of 38-40 DEG C, soaking the working fluid for 15-20 min, and then washing the working fluid for 20-25 min; the softening treatment comprises the steps of adopting a bath ratio of 1:30-1:40 in the warm water, selecting softening smoothing agent A80 which accounts for 2%-4% of the weight of the fabric to soak for 20-30 min, and then conducting dehydration for 5-6 min; the drying treatment comprises the steps of conducting drying at 50-65 DEG C for 30-40 min. The after finishing technology of the woolen knitted fabric has the advantages that by adjusting components of detergent, the detergent still has activity in a low temperature state as that in a high temperature state, and thus the washing effect at a low temperature is constant or even better; meanwhile, softening agent with a structure of short chain segment and a small molecular is selected, and permeability of the softening agent at the low temperature is increased so as to guarantee the after finishing effect and achieve the purpose of reducing energy consumption and carbon discharge.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a finishing process for wool knitted fabrics. Background technique [0002] As a major energy consumer and carbon dioxide emitter, the textile industry has become an inevitable development trend to develop textile finishing technologies with low energy consumption and low emissions under the situation of rising international crude oil prices and increasingly stringent international and domestic requirements for environmental protection and carbon emissions. . Common wool fabrics often have pilling and large weight loss after finishing. At the same time, fuel costs are high and carbon emissions are large. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the prior art, and now provide a finishing process for wool knitted fabrics that can effectively improve the fluffing phenomenon of finished products, and can save energy...
