Preparation method of ultra-thin woven fabric with anti-ultraviolet photocatalytic antibacterial and waterproof function

Abstract

The invention provides a method for preparing an ultra-thin woven fabric with anti-ultraviolet photocatalysis, antibacterial and waterproof functions, which includes weaving, shaping, finishing and molding; the fiber raw materials used in the weaving include anti-ultraviolet and antibacterial polyester or nylon. The product obtained by the method of the invention can simultaneously have three excellent functional effects of anti-ultraviolet / antibacterial and waterproof. In terms of anti-ultraviolet, the ultraviolet protection factor (UPF) value can reach 100, reaching the highest anti-ultraviolet standard UPF value of 50+, which is about 100% higher than other methods, and the antibacterial effect can reach 99% under photocatalysis (sunlight) %, at the same time, it can also stably ensure that the waterproof level of the fabric is 4.

Description

technical field [0001] The invention relates to the field of textile technology, in particular to a method for preparing an ultra-thin woven fabric with anti-ultraviolet photocatalysis, antibacterial and waterproof functions. Background technique [0002] With the improvement of people's quality of life, the demand for clothing functionality has gradually increased. Especially in recent years, the environment has deteriorated, the atmospheric ozone layer has been severely damaged, and the ozone layer is thin or even empty, which leads to an increase in the ultraviolet content directly radiated to the ground, which increases the damage to the human body. Ultraviolet rays are divided into near ultraviolet rays (UVA), mid-wavelength ultraviolet rays (UVB), far ultraviolet rays (UVC) and vacuum ultraviolet rays (UVD). UVA can penetrate the skin and cause melanin precipitation. Long-term exposure can destroy elastic fibers and collagen fibers, making the skin Wrinkle aging loses...

Problems solved by technology

Especially in recent years, the environment has deteriorated, the atmospheric ozone layer has been seriously damaged, and the ozone layer is thin or even empty, which leads to an increase in the ultraviolet content directly radiated to the ground, which increases the damage to the human body.

Ultraviolet rays are divided into near ultraviolet rays (UVA), mid-wavelength ultraviolet rays (UVB), far ultraviolet rays (UVC) and vacuum ultraviolet rays (UVD). UVA can penetrate the skin and cause melanin precipitation. Long-term exposure can destroy elastic fibers and collagen fibers, making the skin Wrinkle aging loses elasticity, which is the component with the highest ultraviolet content; UVB penetrating ability is not as good as UVA, basically absorbed by the ozone layer of the atmosphere, and the content reaching the ground is relatively small, but in recent years, due to the destruction of the ozone layer, UVB can penetrate the atmosphere to reach the surface , due to its shorter wavelength, stronger energy and greater destructive power, it is market demand to develop new fabric products by using functional materials reasonably and effectively

[0003] However, in practice, the weaving of functional fabrics, especially the preparation of anti-ultraviolet and waterproof composite functional fabrics, cannot simultaneously take into account the excellent functional effects of anti-ultraviolet, antibacterial and waterproof.

In the prior art, more simple coatings of anti-ultraviolet agents are used, which will endow the fabric with anti-ultraviolet function, but because sportswear needs to be washed frequently, it is difficult to overcome the shortcoming of not being resistant to washing after coating. Coating, the two coating methods cannot be unified and coordinated, which makes it impossible to achieve a higher level of waterproofing, and it is easy to breed bacteria due to sweating during exercise, which is not good for your health
