Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of laminated composite fabric, and particularly relates to an anti-pilling wear-resistant composite fabric and a preparation method thereof. BACKGROUND

[0002] Polyester fabric, also known as polyester fabric, has high strength, good weather resistance and good dimensional stability, and is popular in both civilian and industrial use. However, due to the chemical composition and structural characteristics of polyester fiber itself, it is prone to pilling during use, and the pilling makes the fabric lack wear resistance, which is difficult to meet the comfortable and high-end clothing requirements.

[0003] In view of the pilling problem of polyester fabric, the traditional technology adopts low-adhesion chip spinning, profile spinning and other processes to increase the cohesion between fibers, which can optimize the anti-pilling performance to a certain extent, and the anti-pilling grade can reach about 3.5 level, but it is still difficult to meet the requirements of high-grade clothing fabric, and the profile spinning requires improvement of the spinneret and other equipment, which makes the fabric production equipment lack universality; in the prior art, the film material is combined with the polyester base cloth through laminated composite technology, and the fibers are fixed to avoid fiber sliding from the source, effectively solving the problem of fabric pilling, and the change of production line and equipment is small.

[0004] Polyester film, such as PET (polyethylene terephthalate), has high strength, high wear resistance and suitable cost, and is an optimal surface layer material for anti-pilling fabric. However, polyester material has poor air permeability, which is good for industrial fabrics such as tarpaulin and waterproof cloth, but poor for comfortable clothing fabric; in the prior art, ultra-fine fillers are introduced into polyester material as pore-forming agents, and a stretching process is used to obtain a polyester film layer with a certain porosity, which is combined with traditional fabric to obtain good moisture permeability. However, the pore-forming effect of these ultra-fine fillers is generally poor, and the filler separates from the polyester matrix during the stretching process, resulting in deterioration of the mechanical properties of the film layer. A large amount of filler is prone to crack in the film material during the stretching process, resulting in a decrease in the waterproofness of the film layer, and a contradiction between moisture permeability, waterproofness and mechanical properties, which restricts the development of anti-pilling fabric. SUMMARY

[0005] In order to solve the technical problems mentioned in the background art, the purpose of the present application is to provide an anti-pilling wear-resistant composite fabric and a preparation method thereof.

[0011]

[0012] Step A2: the photosensitizer is dissolved in acetone and then added to the intermediate and stirred, ultraviolet irradiation is carried out at 350-400mW / cm 2 mercaptoethanol is slowly added and stirred for 3.8-4.4h, and acetone is removed by rotary evaporation to obtain a modified monomer;

[0013] Further, the amount ratio of the intermediate, mercaptoethanol, photosensitizer and acetone is 0.1mol:0.2mol:30-40mg:65-80mL, under the initiation of ultraviolet, the photosensitizer promotes the click addition reaction of the intermediate and mercaptoethanol, and the specific reaction is as follows:

[0014]

[0015] Step A3: terephthalic acid, ethylene glycol and the modified monomer are premixed, antimony glycol is added, nitrogen is introduced for protection, the temperature is increased to 220-230 DEG C, esterification is carried out for 3-3.5h, then titanium glycol is added, the pressure is reduced to 0.1kPa, the temperature is increased to 270-280 DEG C, polycondensation is carried out for 1.5-2h, the material is discharged and cooled to obtain the modified polyester resin;

[0016] Further, the alcohol acid molar ratio of terephthalic acid, ethylene glycol and modified monomer is 1.4-1.55, the molar ratio of ethylene glycol and modified monomer is 1:0.18-0.26, the amount of ethylene glycol antimony is 50-60ppm, the amount of ethylene glycol titanium is 10-15ppm; the modified monomer and ethylene glycol are copolymerized with terephthalic acid.

[0017] Preferably, the lubricant is a polyester wax, which has good internal and external lubrication effects in the modified polyester resin matrix.

[0018] A preparation method of an anti-pilling wear-resistant composite fabric, comprising the following steps:

[0019] Step S1: mixing nano active alumina, a compatibilizer, a lubricant, an antioxidant, a light stabilizer and a modified polyester resin, extruding and calendering at 260-270 DEG C to form a blank film, and then bidirectionally stretching the blank film to obtain a moisture-permeable polyester film;

[0020] Step S2: sequentially attaching a hot melt adhesive mesh film and the moisture-permeable polyester film to the surface of the base cloth, and hot-pressing to form a composite fabric.
