Embodiment 1

[0030] like figure 1 As shown, a strong sunscreen umbrella fabric, the umbrella fabric is a two-layer composite structure, including a waterproof fabric layer 1 and an anti-ultraviolet composite film layer from the outside to the inside, and the anti-ultraviolet composite film layer is a black and white composite film layer 2 .

[0031] like figure 2 As shown, one side of the black and white composite film layer 2 is a white reflective layer 21 , and the other side is a black layer 22 , and the white reflective layer 21 is attached to the waterproof fabric layer 1 . The white reflective layer 21 contains 15% by mass of reflective particles SiO 2 , the black layer 22 contains 20% by mass of light-absorbing particle carbon black.

[0032] The waterproof fabric layer 1 is made of polyester woven high-density grey fabric through waterproof finishing. The linear density of the yarns in the polyester woven high-density fabric is 30D, and the sum of the warp and weft densities is...

Embodiment 2

[0044] like figure 1 As shown, a strong sunscreen umbrella fabric, the umbrella fabric is a two-layer composite structure, including a waterproof fabric layer 1 and an anti-ultraviolet composite film layer from the outside to the inside, and the anti-ultraviolet composite film layer is a black and white composite film layer 2 .

[0045] like figure 1 As shown, one side of the black and white composite film layer 2 is a white reflective layer, the other side is a black layer 22 , and the white reflective layer 21 is attached to the waterproof fabric layer 1 . The white reflective layer 21 contains 5% by mass of reflective particles SiO 2 , the black layer 22 contains 10% by mass of light-absorbing particle carbon black.

[0046] The waterproof fabric layer 1 is made of polyester woven high-density grey fabric through waterproof finishing. The linear density of the yarn in the polyester woven high-density fabric is 20D, and the sum of the warp and weft densities is 400 thread...

Embodiment 3

[0058] like figure 1 As shown, a strong sunscreen umbrella fabric, the umbrella fabric is a two-layer composite structure, including a waterproof fabric layer 1 and an anti-ultraviolet composite film layer in turn from the outside to the inside, and the anti-ultraviolet composite film layer is a black and white composite film layer 2 .

[0059] like figure 2 As shown, one side of the black and white composite film layer 2 is a white reflective layer 21, and the other side is a black layer 22. The white reflective layer 21 and the waterproof fabric layer 1 are attached together. The white reflective layer 21 contains 15% by mass of reflective particles SiO 2 , the black layer 22 contains 15% by mass of light-absorbing particle carbon black.

[0060] The waterproof fabric layer 1 is made of polyester woven high-density grey fabric through waterproof finishing. The linear density of the yarns in the polyester woven high-density fabric is 10D, and the sum of the warp and weft ...

Abstract

The invention belongs to the technical field of umbrella fabric preparation, and particularly relates to a strong sunscreen umbrella fabric and a preparation method thereof. The high-sun-protection umbrella fabric is of a two-layer composite structure and sequentially comprises a waterproof fabric layer and an anti-ultraviolet composite film layer from outside to inside, the waterproof fabric layer is made of polyester high-density gray fabric through waterproof finishing, the linear density of yarns in the polyester high-density fabric is 10-40 D, and the sum of the warp density and the weft density is 350-450 pieces per inch. The prepared umbrella fabric is free of peculiar smell, has high sunscreen and high wear-resistant effects, has the ultraviolet-proof coefficient UPFAV larger than 2000, has waterproofness which can reach 90% or above, can effectively prevent ultraviolet rays from hurting the human body, is dual-purpose in sunny and rainy days, is convenient to produce, low in cost and durable, and has high market popularization value.

Description

technical field [0001] The invention belongs to the technical field of preparation of umbrella fabrics, and particularly relates to a strong sunscreen umbrella fabric and a preparation method thereof. Background technique [0002] Umbrella is an indispensable practical tool at home, especially in the hot summer, when it is rainy and high temperature, direct sunlight, the ultraviolet rays in the sun not only cause melanin and pigmentation on our skin, but also can cause sunburn and aging of human skin. More serious can also induce cancer, endanger human health. A sunscreen umbrella with both rain and UV protection functions is particularly important for people's daily travel. [0003] At present, in the preparation process of most umbrella fabrics, the method of coating is used to prevent ultraviolet rays. The umbrella prepared in this way is prone to wear and tear of the coating due to folding back and forth during use, which greatly reduces its sun protection function. Th...
