Embodiment 1

[0034] This embodiment relates to the milling process of woolen sweaters, including cleaning treatment, milling treatment and dehydration and drying steps. The specific process is as follows: 1) Cleaning treatment: immerse the woolen sweaters in batches in the cleaning solution with a liquor ratio of 1 :20, soak for 10 min at 25°C, deliquify the soaked sweaters, and obtain the first batch of wet sweaters and the second batch of wet sweaters and subsequent wet sweaters. The cleaning solution used in this embodiment is composed of 1.5% sodium citrate, 3.6% amino acid surfactant and water.

[0035] 2) Milling treatment:

[0036] For the first batch of wet woolen sweaters, step a: immerse the first batch of wet woolen sweaters in the milling solution with a bath ratio of 1:40, and mill them at 35°C for 30 minutes to obtain the first Batches of finished sweaters. The first batch of finished woolen sweaters and the second batch of wet woolen sweaters were jointly immersed in clear...

Embodiment 2

[0040] The difference between this embodiment and embodiment one mainly lies in: 2) the formula of the milling liquid that adopts in the milling treatment process is by mass fraction, by 2.8% subtilisin, 4.8% chitin and 8% microcrystalline cellulose composition.

Embodiment 3

[0042] The main difference between this example and Example 1 is that the milling liquid formula used is composed of 3.6% subtilisin, 6.6% chitin and 10% microcrystalline cellulose in terms of mass fraction.

Abstract

The invention relates to a fulling process of a woolen sweater, belongs to the technical field of fulling finishing and aims to solve the problem that a fulling treatment consumes a great number of reagents. According to the technical scheme, the fulling process comprises the following steps: carrying out cleaning treatment, fulling treatment and dehydration drying; soaking a woolen sweater into acleaning solution for 8-12 minutes at 18-25 DEG C, and removing the cleaning solution so as to obtain a moistened woolen sweater; soaking the moistened woolen sweater and a finished product woolen sweater into clean water, carrying out ultrasonic treatment, soaking the moistened woolen sweater into a fulling liquid, and carrying out fulling treatment for 25-35 minutes at 28-40 DEG C so as to obtain a finished product moistened woolen sweater; carrying out ultrasonic treatment on the finished product woolen sweater and a moistened woolen sweater of a next batch, dehydrating the finished product woolen sweater after ultrasonic treatment, and drying at 70-80 DEG C. The fulling process has effects of being small in reagent consumption and environmentally friendly and pollution-free, and is applied to fulling finishing on woolen sweaters.

Description

technical field [0001] The invention relates to the technical field of milling finishing, in particular to a milling process for woolen sweaters. Background technique [0002] Wool sweaters are wool knitwear made of animal hair fibers such as wool and cashmere as the main raw materials. Because wool and cashmere fibers are protein fibers, the surface is covered with dense scales, and the friction coefficient of the fiber's positive scales is smaller than that of the reverse scales. Under the action of external force, it will produce a micro-friction effect and has shrinkage. In order to improve and enhance the internal quality and external effect of woolen sweaters, in the finishing process, the woolen sweater will be milled using the characteristics of woolen wool. [0003] In the prior art, the milling finishing of woolen sweaters usually adopts detergent milling or solvent milling, and solvent washing is to wash the woolen sweaters with tetrachlorethylene before milling,...
