Description

Technical Field

[0001] The invention belongs to the technical field of fabric finishing, and in particular relates to a method for processing dust and pollen-proof cotton-containing dark trousers fabric. Background Art

[0002] With the development of society, people have higher and higher requirements for the wearability and appearance quality of clothing fabrics, especially dark fabrics. Often, due to friction during wearing, electric charge adsorption is generated, and the hairiness of the cloth surface is linked to external foreign fibers, resulting in dust, gray stains, pollen and other adhesion phenomena in the air, making the dark fabrics show foreign objects, and the appearance quality of clothing is poor. Therefore, it is urgent to develop a dark fabric that is anti-pollen and dust-staining and has a certain anti-flowering effect, so that consumers are not easy to be attached to pollen, dust and flowering when wearing. Even if attached, a light flick will cause the powder, dust and flowering to fall off, so that consumers can wear comfortably and at ease. Chinese invention patent CN112430953A discloses a finishing process for dust-proof denim fabrics, and the denim fabrics after ozone post-finishing are sprayed with dust-proof finishing agents, but the treatment can achieve dustproof in a short time, but the duration is short, and it is limited to denim fabrics, and the applicability is low. Chinese invention patent CN103774365A discloses a worsted fabric that is resistant to wool and dust staining and a production method thereof. The fabric is made by strip dyeing, recombing, spinning, weaving, and finishing in sequence. During the finishing, the fabric is singed after wet finishing and drying, and an anti-pollen finishing agent is used to perform a wool and dust staining resistant finishing on the fabric. The process flow of this method is complicated, and the wool and dust staining resistant effect is not significant. Summary of the invention

[0003] The purpose of the present invention is to provide a method for processing dust and pollen-proof cotton-containing dark trouser fabrics. The method is simple, can significantly improve the problem of foreign-color adsorption of dark fabrics, and improves the appearance quality of products.

[0004] The present invention is achieved through the following technical solutions:

[0005] The method for processing dust and pollen-proof cotton-containing dark trouser fabric of the present invention comprises the following steps:

[0017] Preferably, the tentering setting is carried out at a temperature of 180-190°C and a speed of 25-30 m / min.

[0018] Preferably, preshrinking is carried out on a preshrinking machine, with a rubber blanket pressure of 0.13-0.15 MPa, a rubber blanket temperature of 100-110° C., a wool blanket temperature of 110-120° C., and a machine speed of 50-60 m / min.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

In particular, the present invention uses the dust-proof additive LESPOLLEN PRE-50, and the obtained fabric has a pollen-proof test of level 3 before washing, and remains unchanged after 10 washes; the dust-proof test reaches level 4 before washing, and remains unchanged after 10 washes; and the dust-proof test can withstand 10 home washings. Dark fabrics have good dust and pollen-proof effects in both wet and dry states. The present invention uses the antistatic agent JEA:30, which significantly improves the problem of fabric friction static adsorption of dust.

[0021] The method of the present invention is not only applicable to dark trouser fabrics, but also has obvious improvement effects on other dark clothing, such as coats, skirts, shirts and other woven fabrics. It has a wide range of applications, and the quality of the processed fabrics is stable. It effectively improves the problems of dark fabric products such as hair sticking and dust absorption, and has broad market prospects. BRIEF DESCRIPTION OF THE DRAWINGS
