Problems solved by technology

However, this method needs to set up a small skylight structure and a wind and snow structure, the manufacturing process is complicated, and the size of the tarpaulin needs to be cut according to the needs before the small skylight structure can be installed in a suitable position, which is not conducive to the high-efficiency mass production of the tarpaulin
In addition, the surface of this kind of tarpaulin is flat. When there is water on the surface of the tarpaulin, th...

preparation example Construction

[0061] A preparation method of a waterproof breathable coated textile, comprising the following steps:

[0062] Step (1), material preparation: prepare a breathable cover layer, a coating liquid and a base material and a convex strip made of fibers; the coating liquid is N, N-dimethylformamide, polyurethane and a bridging agent Prepared according to the mass ratio of 1: (3-5): (0.1-0.4);

[0063] Step (2), forming a waterproof and breathable coating: evenly coat the coating liquid on the upper surface of the substrate, keep it for 5-15 minutes, then put the substrate coated with the coating liquid into 30-50°C water, Keep it for 8-24 hours, take it out, and dry it to obtain a substrate with a waterproof and breathable coating;

[0064] Step (3), the convex strips are evenly spaced and substantially parallel to each other on the waterproof and breathable coating, and the adhesive is evenly sprayed along the length direction of the convex strips at the interval between adjacent...

Embodiment 1

[0092] A waterproof and breathable coated textile, comprising a base material 4, a waterproof and breathable coating 3, a convex strip 2 and a covering layer 1, the upper surface of the base material 4 is coated with a waterproof and breathable coating 3, and the waterproof and breathable coating On the outer surface of the layer 3, a plurality of convex strips 2 are evenly spaced, and the covering layer 1 is breathable and covered on the plurality of convex strips 2 to form a convex portion, and a groove portion is formed between adjacent convex strips 2 ; At the position of the groove part, the inner surface of the covering layer 1 is directly bonded to the waterproof and breathable coating 3; the base material 4 and the protruding strip 2 are both fiber products.

[0093] The ridges 2 are parallel to each other and formed by scattered short fibers; the length of the short fibers is 20-100mm, and the linear density is 3.1-8.5dtex; the short fibers are hydrophobic chemical fib...

Embodiment 2

[0100] Embodiment two: embodiment two is basically the same as embodiment one, the difference is that in the waterproof breathable textile of embodiment two, the lower surface of substrate 4 is also coated with waterproof breathable coating. When forming a waterproof and breathable coating in step (2), the lower surface of the substrate 4 is also uniformly coated with the coating liquid, and finally a waterproof and breathable coating is also formed on the lower surface of the substrate 4, which is called the second waterproof and breathable coating. Layer 7.

Abstract

The invention relates to the technical field of textile products, in particular to a textile product with a waterproof breathable coating and a method for preparing the textile product. The textile product comprises a base material, the waterproof breathable coating, a cover layer, and a plurality of cords or coarse fiber strips and fine fiber strips. The waterproof breathable coating is coated onthe upper surface of the base material, the cords or the coarse fiber strips and the fine fiber strips are uniformly arranged on the outer surface of the waterproof breathable coating at intervals, the cover layer can breathe and covers the multiple cords or the coarse fiber strips and the fine fiber strips, and protrusions and grooves are formed. The textile product and the method have the advantages that the textile product has excellent waterproof breathable functions and is excellent in thermal insulation property and drainage and long in service life; besides, processes for preparing thetextile product are simple and are high in production efficiency, mass industrial production can be facilitated, and the textile product and the method have broad market prospects.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a waterproof and breathable coated textile and a preparation method thereof. Background technique [0002] Tarpaulin is a kind of commonly used industrial textiles. It is generally required that the tarpaulin has waterproof, acid and alkali resistance, corrosion resistance, flame retardancy, and high strength. It is usually coated with polyvinyl chloride to make the tarpaulin waterproof. However, while considering the waterproof performance, it is often overlooked that the tarpaulin needs a certain degree of air permeability in some application scenarios, such as tarpaulins used to make camping tents or to cover some goods that need to be breathable. In order to provide a tarpaulin with good air permeability, Chinese patent CN2302971Y provides a skylight tarpaulin, which has a small skylight structure on the tarpaulin body, and a wind and snow prevention structure at the skyligh...
