preparation example Construction

[0022] The sunscreen fabric provided by the embodiment of the present invention can be prepared by the following method, and the preparation method includes the following steps 1-3.

[0023] Step 1: Put the fabric base material into the finishing solution for padding, then take it out, let it stand and dry it. The finishing solution contains titanium dioxide powder, and the particle size of the titanium dioxide powder in the finishing solution is not greater than 70nm. Specifically, the fabric base material is put into the finishing liquid for 15-50 minutes for padding, and the temperature is 80° C., and the drying temperature of the fabric base material after the finishing liquid is taken out is 90° C. The components of the finishing solution include 30-70 parts by weight of alcohol, 20-50 parts by weight of ethyl acetate and 8-20 parts by weight of titanium dioxide powder. The suspension system formed by mixing the components and stirring at a high speed is the finishing solu...

Embodiment 1

[0028] A method for preparing sunscreen fabrics, comprising the following steps.

[0029] Step 1: Under the condition of 80°C, put the clean polyester fabric substrate into the finishing solution for padding for 35 minutes, then take it out, let it stand and dry it at 90°C. The finishing solution includes 50 parts by weight of alcohol, 30 parts by weight of ethyl acetate and 23 parts by weight of titanium dioxide powder, the particle size of the titanium dioxide powder in the finishing solution is not greater than 30nm, and the finishing solution is to mix alcohol, ethyl acetate and titanium dioxide powder in proportion Afterwards, the suspension system formed by high-speed stirring. Through weighing comparison before and after, the mass proportion of titanium dioxide powder on polyester fiber is 21.3%.

[0030] Step 2: Soak the polyester fabric base material prepared in step 1 in the first coating for 1 hour and dry it. The drying is carried out in a gradient temperature ris...

[0034] A method for preparing sunscreen fabrics, comprising the following steps.

[0035] Step 1: Under the condition of 80°C, put the clean polyester fabric substrate into the finishing solution for padding for 35 minutes, then take it out, let it stand and dry it at 90°C. The finishing solution comprises 50 parts by weight of alcohol, 30 parts by weight of ethyl acetate and 23 parts by weight of titanium dioxide powder, the particle size of the titanium dioxide powder in the finishing solution is 20-40nm, and the finishing solution is to mix alcohol, ethyl acetate and titanium dioxide powder in proportion Afterwards, the suspension system formed by high-speed stirring. Through weighing before and after comparison, the mass proportion of titanium dioxide powder on polyester fiber is 23.7%.

[0036] Step 2: Soak the polyester fabric substrate prepared in step 1 in the first coating for 1 hour and dry it. The drying is carried out in a gradient temperature rise method, and it ...

Abstract

The present application relates to the technical field of textile products, in particular to a preparation method of a sunscreen fabric, a sunscreen fabric and a sunscreen umbrella. The preparation method of the sunscreen fabric comprises the following steps: putting the fabric base material into the finishing solution for padding, taking it out, standing it and drying it, the finishing solution contains titanium dioxide powder, and the particle size of the titanium dioxide powder in the finishing solution is not greater than 70nm; The substrate is dried after soaking in the first coating, the first coating contains titanium dioxide powder, and the particle size of the titanium dioxide powder in the first coating is 70-130nm; the first coating surface on the fabric substrate side is coated with the second The paint, the second paint contains titanium dioxide powder, and the particle size of the titanium dioxide powder in the second paint is 130-300nm. The large particles of titanium dioxide powder on the surface and middle layer of the fabric realize the reflection and scattering of ultraviolet rays, blocking most of the ultraviolet rays, and the small particles of titanium dioxide attached to the inner fabric fibers realize the partial ultraviolet rays penetrating through the second coating and the first coating. to absorb.

Description

technical field [0001] The present application relates to the technical field of textile products, in particular to a preparation method of a sunscreen fabric, a sunscreen fabric and a sunscreen umbrella. Background technique [0002] In the existing technology, in order to realize the sun protection effect and effectively reflect and absorb ultraviolet rays, the sunny and rainy umbrella cloth is usually coated with a sun protection coating on the umbrella surface, which has good heat reflectivity and can maintain a suitable temperature under the sun protection umbrella under direct sunlight , to make the human body feel comfortable, and at the same time have the function of anti-ultraviolet rays, and the effect of sun protection is good. The coated cloth of the umbrella surface increases the sun protection function of the cloth, avoids the adverse effects of ultraviolet rays in the strong sun, and effectively avoids sunburn. The existing sunscreen umbrella cloth is usually...
