Embodiment 1

[0011] A high-density waterproof coated fabric, including a base cloth layer and at least one layer of coating, wherein the base cloth is formed by interweaving warp yarns and weft yarns, and the warp yarns and weft yarns are respectively blended from polyester fibers and silk fibers, wherein the silk fibers The specific gravity is 20%, the warp density of the base fabric layer is 150 strands / cm, and the weft density is 180 strands / cm. A layer of slurry coating is coated on the base fabric. The slurry coating consists of the following components in parts by mass : 50 parts of modified polyurethane resin, 6 parts of silane coupling agent, 7 parts of crosslinking agent, 0.5 part of pigment and 12 parts of toluene.

Embodiment 2

[0013] A high-density waterproof coated fabric, including a base cloth layer and at least one layer of coating, wherein the base cloth is formed by interweaving warp yarns and weft yarns, and the warp yarns and weft yarns are respectively blended from polyester fibers and silk fibers, wherein the silk fibers The specific gravity is 35%, the warp density of the base fabric layer is 250 strands / cm, and the weft density is 300 strands / cm. A layer of slurry coating is coated on the base fabric. The slurry coating consists of the following components in parts by mass : 70 parts of modified polyurethane resin, 10 parts of silane coupling agent, 15 parts of crosslinking agent, 1.5 parts of pigment and 18 parts of toluene.

Embodiment 3

[0015] A high-density waterproof coated fabric, including a base cloth layer and at least one layer of coating, wherein the base cloth is formed by interweaving warp yarns and weft yarns, and the warp yarns and weft yarns are respectively blended from polyester fibers and silk fibers, wherein the silk fibers The specific gravity is 28%, the warp density of the base fabric layer is 188 threads / cm, and the weft density is 272 threads / cm. A layer of slurry coating is coated on the base fabric. The slurry coating consists of the following components in parts by mass : 65 parts of modified polyurethane resin, 7 parts of silane coupling agent, 8 parts of crosslinking agent, 1 part of pigment and 15 parts of xylene.

[0016] The excellent effects achieved by the present invention will be further illustrated through specific experiments below.

Abstract

The invention relates to a high-density waterproof coated fabric. The high-density waterproof coated fabric comprises a base cloth layer and at least one coating, wherein the base cloth layer is formed by weaving of warp yarns and weft yarns, the warp yarns and the weft yarns are formed by polyester fibers and silk fibers through blending respectively, the silk fibers account for 20-35%, the warp density of the base cloth layer is 150-250 / cm, and the weft density of the base cloth layer is 180-300 / cm; the base cloth layer is coated with a sizing agent coating which is prepared from the following components in parts by mass: 50-70 parts of modified polyurethane resin, 6-10 parts of a silane coupling agent, 7-15 parts of a cross-linking agent, 0.5-1.5 parts of pigment, and 12-18 parts of solvent. The high-density waterproof coated fabric provided according to the technical scheme has the characteristics of lightness, thinness, excellent elasticity, good waterproof effect and stable coating performances, can well protect a down feather interlayer and is very suitable for serving as the coating fabric of the down garments.

Description

technical field [0001] The present invention relates to a coated fabric. Background technique [0002] Down clothing is a kind of warm clothing with good thermal performance. It is composed of two or more layers of coated fabric layers and down interlayers. The thermal performance of down clothing is not only related to the quality of down, but also related to the weight of down. Due to processing or its own material problems, the fabric layer is prone to "running down" phenomenon, and the down interlayer is affected by water, and its thermal performance will decline. Therefore, down clothing has higher requirements for the coated fabric layer. [0003] High-density coated fabric is a functional fabric formed after high-density base fabric is finished and coated. Generally, high-density coated fabric has the dual advantages of high-density fabric and coated fabric, and has the characteristics of light weight, softness, fineness, smoothness, good hand feeling and good elasti...
