Embodiment 1

[0044] An anti-pilling coat comprises a coat body, the raw material of which is obtained through anti-pilling agent treatment. In parts by weight, the raw material components of the anti-pilling agent are shown in Table 1.

[0045] The treatment process of coat material includes the following steps:

[0046]Step 1, the preparation of silicone modifier: Stir the metered hydrogen-containing silicone oil and allyl alcohol polyoxyethylene ether evenly, add chloroplatinic acid after heating up to 80°C, and pass through nitrogen protection, and then heat up to 90- 100°C, keep warm for 4-5h and remove water to obtain silicone modifier;

[0047] Step 2, the preparation of water-based polyurethane prepolymer: add dibutyltin dilaurate to the measured polyethylene glycol, heat up to 70°C and pass nitrogen protection, add measured isophorone diisocyanate and keep it warm for 1-2h, Then add N-methyloldiethanolamine and keep it warm for 1-2 hours, lower the system temperature to 15-20°C, ...

Embodiment 2

[0051] The difference from Example 1 is that, in parts by weight, the raw materials of the anti-pilling agent are shown in Table 1.

Abstract

The invention discloses an anti-pilling overcoat comprising an overcoat body; raw materials of the overcoat body are treated by using an anti-pilling agent; raw materials of the anti-pilling agent include waterborne polyurethane prepolymer and an organic silicon modifier; and the waterborne polyurethane prepolymer comprises the following components: isophorone diisocyanate, polyethylene glycol anda chain extender. The anti-pilling overcoat has the following advantages that waterborne polyurethane is synthesized by isocyanate, polyether polyol, a small-molecular chain extender and an end capping agent. A polyurethane molecule contains a great deal of carbamate and carbamido and is good in film forming property and wear resistance, high in adhesive force and excellent in mechanical properties. A waterborne polyurethane polymer can form a net structure with a certain crosslinking degree together with a fiber structure, so that the phenomena such as winding and pilling of the fiber are effectively avoided and relieved, and furthermore, the anti-pilling and anti-fuzzing performances of a fabric are greatly improved. Compared with polyacrylate, polyurethane is more excellent in performance, however, the neatened fabric is relatively hard in handfeel to affect the wearing comfort level of a textile.

Description

technical field [0001] The invention relates to the field of clothing, more specifically, it relates to an anti-pilling coat and its treatment process. Background technique [0002] Pilling is caused by the friction on the surface of the fabric, and the fibers are entangled together into a ball shape. Traditional coats are usually made of woolen fabrics, which are not easy to pill, but with the improvement of aesthetic and comfort requirements, the fabrics of coats are becoming more and more diverse. At present, polyester / cotton blended fabrics are mostly produced, but these The materials are very easy to pill. [0003] The patent with the notification number CN104195830B discloses an anti-pilling agent for wool fabrics, which is composed of the following substances in parts by mass: 15-20 parts of ethyl acrylate; polyoxyethylene octylphenyl alcohol 15-20 parts; 10-15 parts of zinc nitrate; 5-8 parts of stearic acid; 5-8 parts of sodium sulfate; 2-4 parts of n-butanol; 2-4...
