Embodiment 1

[0029] Embodiment 1 Cryogenic treatment improves the anti-pilling performance of wool knitted fabrics

[0030] Cleaned wool knitted fabrics (Zhejiang Sande Textile Co., Ltd.) were placed in a cryogenic treatment device (SLX-30). Tightly cover the container of the cryogenic treatment equipment to avoid leakage of low-temperature liquid nitrogen, affecting the accuracy of temperature control and treatment effect, and set the cryogenic treatment process parameters, as shown in Table 1. After the treatment is completed, when the ambient temperature of the container reaches room temperature, the wool knitted fabric is taken out, and the modification treatment process is completed.

[0031] The cryogenically treated wool knitted fabrics were tested using the GB / T 4802.2 Determination Standard for Fabric Pilling Properties. The test results are as follows: before cryogenic treatment, the test grade of wool knitted fabric is 2.8, which is a qualified product; after cryogenic treatmen...

Embodiment 2

[0034] Embodiment 2 Cryogenic treatment improves the anti-fluffing performance of worsted wool woven fabric

[0035] Cleaned worsted wool woven fabrics (Shandong Nanshan Textile & Garment Co., Ltd.) were placed in cryogenic treatment equipment (SLX-30). Cover the container of the cryogenic treatment equipment tightly to avoid leakage of low-temperature liquid nitrogen, which will affect the accuracy of temperature control and treatment effect, and set the cryogenic treatment parameters according to Table 2.

[0036] After the treatment is completed, when the ambient temperature of the container reaches room temperature, the worsted wool woven fabric is taken out, and the modification treatment process is completed.

[0037] Worsted wool woven fabrics were tested using GB / T 4802.1 Determination Standard for Fabric Pilling Properties. The test results are as follows: before the cryogenic place, the grade of the worsted wool woven fabric is 3.2, which is a qualified product; aft...

Embodiment 3

[0040] Example 3 Cyclic cryogenic treatment reduces the pilling performance of wool knitted fabrics

[0041] Cleaned wool knitted fabrics (Zhejiang Sande Textile Co., Ltd.) were placed in a cryogenic treatment device (SLX-30). Tightly cover the container of the cryogenic treatment equipment to avoid leakage of low-temperature liquid nitrogen, affecting the accuracy of temperature control and treatment effect, and set the cryogenic treatment parameters according to Table 3.

[0042] After the treatment is completed, when the ambient temperature of the container reaches room temperature, the wool knitted fabric is taken out, and the modification treatment process is completed.

[0043] The wool knitted fabric is tested by GB / T 4802.2 Determination standard of fabric pilling performance. The test results are as follows: before the cryogenic treatment, the test grade of the wool knitted fabric is 2.8, which is a qualified product; after the cryogenic treatment, the test grade of ...

Abstract

A subzero treatment method for retaining fuzzing and pilling of wool fabric includes the steps of at least one time of subzero treatment and temperature raising-back treatment. The temperature of thewool fabric subjected to the subzero treatment is raised back to the room temperature and then kept for 2-10 hours, then the next time of subzero treatment and temperature raising-back treatment are conducted, and the technological parameters of all times of subzero treatment and temperature raising-back treatment are the same or different; the subzero treatment is conducted on the wool fabric with the treatment temperature controlled to be -200 DEG C to -100 DEG C and the treatment time of 1-15 hours; according to the temperature raising-back treatment, the wool fabric subjected to the subzero treatment is taken out, and the temperature is naturally raised back to the room temperature or raised back to the room temperature with the temperature raising speed controlled to be 1-20 DEG C perminute. Due to compression stress generated by the subzero treatment method, wool fiber scales can be closely attached to fiber, the upwarp process of a scale layer is restrained, and therefore the fuzzing and pilling degree of the wool fabric is effectively restrained, the surface flatness, color and luster of the wool fabric are increased, and the service life of the wool fabric is prolonged.

Description

technical field [0001] The invention belongs to the field of functional finishing of wool fabrics, and in particular relates to a cryogenic treatment method for inhibiting wool fabrics from fluffing and pilling. Background technique [0002] Wool is a kind of natural protein fiber. It has the advantages of soft hand feeling, firm texture, good luster, strong moisture absorption, and good warmth retention. Therefore, wool clothing has always been favored and valued by people. However, due to the special scale structure on the surface of wool fiber, it is prone to pilling during wearing. The hair balls protruding on the surface of the fabric are easy to absorb dirt and dust, which seriously affects the wearability and appearance of wool fabric. influences. How to overcome the pilling phenomenon has always been a major problem in the wool industry. [0003] Because wool fiber in wool fabric is composed of scale layer and cortex layer, the scale has a certain height and thickn...
