Problems solved by technology

[0004] However, the coating of the above-mentioned anti-ultraviolet and waterproof coated fabric contains a certain amount of nano-titanium oxide. When the base cloth layer is coated and finished, the nano-titanium oxide is easy to react with impurities to generate colored substances, which are attached to the base cloth layer. , making the base cloth after finishing yellowing, affecting the quality of the product

Embodiment 1

[0049] An umbrella cloth includes a fabric layer and a waterproof layer. The fabric layer is blended and woven by polyester fiber and acrylic fiber in a mass ratio of 8:2, and the thickness of warp and weft is 190D. After pre-treatment, the fabric weight after dyeing and / or printing is 100-180g / m 2 . The waterproof layer is finished by a water-repellent finishing liquid.

[0050] The manufacturing method of the above umbrella cloth includes the following steps:

[0051] S1. Perform conventional pre-treatment, dyeing and / or printing on the grey fabric blended with polyester fiber and acrylic fiber, and obtain the pre-treated cloth after reduction washing, water washing and drying;

[0052] S2. Weigh 21.9 parts of polyurethane emulsion, 13.1 parts of polyacrylate emulsion, 7.0 parts of epoxy-modified silicone oil, 3.0 parts of polyether-modified silicone oil, 11.0 parts of isocyanate, 2.5 parts of adhesive, and mix and stir in parts by weight. Evenly formulate into a water-repellent...

Embodiment 2

[0057] An umbrella cloth, which is basically the same as the umbrella cloth of Example 1, except that the thickness of the warp yarn and the weft yarn of the woven fabric layer are both 200D. The content of each component in step S2 in the manufacturing process is 25.0 parts of polyurethane emulsion, 15.0 parts of polyacrylate emulsion, 10.5 parts of epoxy modified silicone oil, 4.5 parts of polyether modified silicone oil, 13.0 parts of isocyanate, adhesive 4.0 parts, 3.0 parts of nano zinc oxide; the concentration of the water-repellent finishing solution in step S3 is 30 g / L.

Embodiment 3

[0059] An umbrella cloth, which is basically the same as the umbrella cloth in Example 1, except that the thickness of the warp yarn and the weft yarn of the woven fabric layer are both 210D. The content of each component in step S2 in the manufacturing process is 28.1 parts of polyurethane emulsion, 16.9 parts of polyacrylate emulsion, 14.0 parts of epoxy modified silicone oil, 6.0 parts of polyether modified silicone oil, 15.0 parts of isocyanate, adhesive 5.5 parts, 4.5 parts of nano zinc oxide; the concentration of the water-repellent finishing solution in step S3 is 45 g / L.

Abstract

The invention discloses an umbrella cloth. The umbrella cloth comprises a fabric layer and a water-proof layer coating the fabric layer. The umbrella cloth is characterized in that the fabric layer isprepared by blending and weaving polyester fibers and acrylic fibers, wherein the water-proof layer is prepared from the following components in parts by weight: 35 to 45 parts of resin, 10 to 20 parts of silicone oil, 11 to 15 parts of cross-linking agent, 2.5 to 5.5 parts of adhesive and 1.5 to 4.5 parts of ultraviolet screening agent; the resin contains polyurethane emulsion and polyacrylate emulsion; the mass ratio of the polyurethane emulsion to the polyacrylate emulsion is 5 to 3; the silicone oil is prepared by mixing epoxy-modified silicone with polyether-modified silicone. The invention also aims at providing a method for manufacturing the umbrella cloth; the manufactured umbrella cloth has the advantages of good water-proof and ultraviolet-proof effects, light resistance and lowpossibility of yellowing while processing.

Description

Technical field [0001] The invention relates to an umbrella cloth and a manufacturing method thereof. Background technique [0002] Umbrella cloth is generally made of conventional fabrics after water repellent finishing. It has good water repellency and sun protection effects. It is the main raw material for making umbrellas and sunshades. [0003] The existing Chinese patent with authorized announcement number CN103774326B discloses an anti-ultraviolet and waterproof coating fabric, which includes a base cloth layer and at least one layer of coating. The base cloth layer is woven by warp yarns and weft yarns. It is composed of 92%-98% nylon fiber and 2%-8% aluminum silicate fiber; the coating is coated on the base cloth layer and is composed of the following components by mass: 40-60 parts of polyurethane emulsion, 3-6 parts of nano titanium oxide, 2-6 parts of nano zinc oxide, 3-7 parts of cross-linking agent, 5-8 parts of acrylate and 10-15 parts of solvent. [0004] However, t...
