Problems solved by technology

There are two main materials for anti-radiation fabrics: one is a veil wrapped with alloy microwires. This material has good air permeability and is resistant to washing. However, according to research, the use of clothing containing metal wires cannot absorb electromagnetic waves, but will cause electromagnetic waves to oscillate. Enhance the radiation of electromagnetic waves; another material is the fabric coated with metal ions on the surface. Although this material can absorb electromagnetic waves, its air permeability and washability are quite poor.

preparation example Construction

[0028] The preparation method of the novel functional composite fabric is characterized in that it is prepared through the following steps:

[0029] Step 1: Use at least one kind of existing fiber raw material and at least one kind of functional particles to blend and then process through electrospinning process or non-woven process to prepare functional fiber layer 1 or add functional particles in the ordinary spinning process to make The functional fiber layer 1 is obtained by attaching to the fiber;

[0030] The fiber raw material adopts synthetic or recycled raw materials such as: polyolefin, polychlorinated olefin, polyester, polyether, polyamide, polyanhydride, polyvinyl alcohol, polyacrylonitrile, polylactic acid, amino acid, epoxy resin or Natural raw materials such as: natural cellulose fiber, silk, soybean fiber, milk fiber, animal fur, spider silk or inorganic materials such as: aluminum, copper, silver, glass, ceramics;

[0031] The functional particles are carbon...

Abstract

The present invention relates to a new-type functional composite face fabric with several functions of resisting static electricity, resisting radiation, resisting bacteria, killing bacteria, filtering toxic material and protecting health, etc. Said composite face fabric includes functional fibre layer, adhered base layer or surface layer face fabric, the above-mentioned all the layers and combined together by means of physical, chemical or mechanical method so as to obtain the invented product.

Description

technical field [0001] The invention belongs to the field of textile and clothing, and relates to a novel functional composite fabric and a preparation method thereof. Background technique [0002] Some analysis shows that in the field of electronic computers, the loss caused by static electricity can reach 5 billion US dollars a year. With the development of the electronics industry, the demand for anti-static clothing is also increasing. At present, anti-static cloth is obtained by adding metal wire fibers to the fabric or by post-finishing to obtain anti-static properties. The former has the disadvantages of poor comfort and weak antistatic performance, while the latter cannot maintain long-lasting antistatic performance. [0003] The problem of electromagnetic radiation has attracted widespread attention at home and abroad in recent years, and it is called "the fourth largest pollution source after water pollution, air pollution and noise pollution" internationally. T...
