Disclosure of Invention
The invention aims to provide a wear-resistant and crease-resistant down jacket fabric and a preparation method thereof, and overcomes the defect that the wear-resistant effect is poor due to the fact that a wear-resistant layer on the surface of an existing down jacket is easy to damage and fall off after the existing down jacket is worn for a period of time.
The invention realizes the purpose through the following technical scheme:
a preparation method of wear-resistant and crease-resistant down jacket fabric comprises the following steps
(1) Mixing cotton fibers and bamboo fibers according to the mass ratio of 1:2-2:1, and interweaving warp yarns and weft yarns to form a primary material;
(2) soaking the primary material in an antibacterial solution for 12-24h, and washing with clear water after soaking;
(3) and coating wear-resistant paint on the outer surface of the primary material, placing the primary material into a kneading and grinding machine for kneading and grinding after the wear-resistant paint is cured, repeating the coating, curing and kneading and grinding operations for three times, and finally coating a layer of wear-resistant paint on the outer surface of the primary material to obtain the wear-resistant and crease-resistant down jacket fabric.
The further improvement is that the mixing mass ratio of the cotton fiber and the bamboo fiber is 1: 1.
The further improvement is that the antibacterial liquid is prepared by mixing 10-30 wt% of chitin, 10-20 wt% of folium artemisiae argyi extract, 5-20 wt% of kasong and 30-50 wt% of deionized water.
The further improvement is that when the wear-resistant coating is coated, the thickness of the first wear-resistant coating is 15-20nm, the kneading rotation speed is 80-100r/min after curing, and the kneading time is 6-8 min; the thickness of the second coating of the wear-resistant coating is 10-15nm, the kneading and rolling speed is 60-80r/min after curing, and the kneading and rolling time is 4-6 min; the thickness of the third coating of the wear-resistant coating is 5-10nm, the kneading rotation speed is 40-60r/min after curing, and the kneading time is 2-4 min.
The further improvement is that the wear resistant coating finally applied to the outer surface of the primary charge has a thickness of 2-10 nm.
The further improvement is that the wear-resistant coating is prepared by mixing 5-20 wt% of zirconium n-propoxide, 5-20 wt% of silicon nitride, 15-25 wt% of isocyanate, 20-25 wt% of epoxy resin and 25-40 wt% of toluene.
The further improvement is that the mass ratio of the zirconium n-propoxide to the silicon nitride in the wear-resistant coating is 1: 1.
The invention also provides wear-resistant and crease-resistant down jacket fabric which is prepared by the preparation method.
The invention has the beneficial effects that: the down jacket fabric is subjected to repeated wear-resistant coating, curing and kneading and rolling operations during preparation, the coating is greatly influenced by bending and abrasion of the fabric when kneading and rolling are started, so that the coating is damaged in a large area, and the coating is damaged in a small area and has small holes due to the buffer effect of the damaged coating before kneading and rolling, so that the coating on the outermost surface is more resistant to bending and abrasion and is not easy to fall off and damage, and the down jacket can keep an excellent wear-resistant effect for a long time after being worn and has a good crease-resistant performance; in addition, the down jacket fabric has better antibacterial property.

Samples of the down jacket fabrics were prepared according to the methods of examples 1 to 3 and comparative examples 1 to 4, respectively, to obtain an area of 400cm2The seven groups of samples are respectively 10 parts, and the performance test of the seven groups of samples comprises the following steps: firstly, observing the appearance of a sample in an initial state and after the sample is folded for 10000 times, and observing whether the coating falls off or folds; secondly, with reference to GB/T21196.2-2007 Standard on determination of fabric wear resistance by the Martindale method of textiles, a wear resistance test is carried out on a down jacket fabric sample in an initial state and after the sample is folded for 10000 times, and the wear resistance index Ai (average mass loss of each friction) of the sample is detected. The results of the performance tests are given in the following table:
