Problems solved by technology

This is the only anti-pilling finishing agent for woolen sweaters in the domestic and foreign markets so far, but the finishing agent is used under the condition of weak alkali, and the woolen sweaters are resistant to acid but not alkali. The color retention is not ideal, and the price is expensive, which affects the industrialization

Embodiment 1

[0013] Select this white cashmere fabric to carry out the test, woolen sweater cleaning pretreatment, reduction pretreatment, washing, centrifugal dehydration, soaking treatment with finishing liquid formaldehyde, drying, cleaning, centrifugal dehydration, softener solution impregnation, centrifugal dehydration, softening Liquid impregnation, centrifugal dehydration, drying. The anti-pilling grade of the fabric after finishing as above can reach above grade 3.5, while the ordinary treated sample without anti-pilling finishing has only grade 2.0.

example 2

[0015] 56 pieces of this white wool fabric were selected for testing, and the anti-pilling finishing of the fabric was carried out according to the above-mentioned implementation method and finishing process. The finishing agent was glyoxal. The ordinary treatment sample of anti-pilling finishing is only 2.0 grade.

[0016] Selecting wool fabrics of different colors and repeating the test, the anti-pilling level of the finished fabrics can reach above 3.5, and the color is very close to the original, with soft, smooth, and good elasticity.

example 3

[0018] Select 56 wool fabrics to test. Malondialdehyde is used as a finishing agent, and the test results have confirmed that when the amount of finishing agent is increased by 0.5 to 1.0 times compared with the general amount, the anti-pilling level can be increased to above 4.0. And the color has no obvious change, and the hand feels soft, smooth and elastic.

Abstract

The present invention discloses a finishing agent for anti-flokkit and anti-balling up finishing to woolen sweater in weak acidic condition. The R in the universal expression (1) compound expresses hydrogen, alkyl or aldehyde group. The said finishing agent is provided with the ability of making woolen sweater achieve over 3.5 rank anti-flokkit finishing effect.

Description

Background technique [0001] Because the structure of wool yarn and fabric is relatively loose, wool fibers are easily pulled or slipped out from the yarn under the action of various friction and pulling forces during use, forming fluff on the surface of the sweater. When the length of the villi increases to a considerable length, the villi tangle together to form small balls. The occurrence of this "pilling--pilling" phenomenon seriously affects the appearance quality of the woolen sweater, and makes the organizational structure unstable, greatly reducing the quality of the woolen sweater. The anti-pilling finishing of woolen sweaters can greatly improve its performance. However, due to the loose structure of woolen sweaters, it is quite difficult to perform this kind of finishing technology. Therefore for a long time, there is no effective anti-pilling finishing agent for woolen sweaters worldwide. [0002] In 2003, Japan's Chiyoda Trading Co., Ltd. launched an anti-pilling...
