Problems solved by technology

There are obvious defects in these two types of golden yellow fibers. On the one hand, the former is expensive. For example, in 2011, Nylstar Corporation of the United States developed a 24K Nylgold gold fiber, which is said to have skin care, beauty, and anti-aging effects, but the price per gram exceeds 90. US dollars; the latter has no shielding and antibacterial effects, and due to the introduction of chrome yellow and medium chrome yellow chemical pigments containing toxic elements chromium, the fastness of the combination between fibers and pigments cannot be compared with "plating", it is difficult to avoid There is a certain degree of pollution, which is not suitable for home textile products
On the other hand, the golden-yellow fiber prepared by the pure gold drawing method does not have the sweat-absorbing, breathable, and comfortable wearing properties of natural cotton fibers, so it is difficult to be used for taking; Fiber, because chemical fiber is used as the base material, the waste after use is difficult to degrade in nature, which is not conducive to environmental protection

Abstract

The invention discloses a preparation method for a silver golden regenerated cellulose fiber / silver golden regenerated cellulose fiber fabric. According to the preparation method, regenerated cellulose fiber and / or regenerated cellulose fiber fabric is taken as a raw material and soluble silver salts are adopted to obtain the golden regenerated cellulose fiber / golden regenerated cellulose fiber fabric, under the action of lewis acid catalysts and by adopting a catalytic nano chemical plating technology. The silver golden regenerated cellulose fiber / silver golden regenerated cellulose fiber fabric has the functions of antibiosis, deodorization, static electricity resistance and anti-electromagnetic radiation, and can be applied to the fields of military, medical treatment, public health, home furnishing and clothing. The regenerated cellulose fiber, adopted as the raw material by the invention, is cotton pulp regenerated cellulose fiber, wood pulp regenerated cellulose fiber, bamboo pulp regenerated cellulose fiber, or sodium alginate regenerated cellulose fiber; the regenerated cellulose fiber fabric, adopted as the raw material by the invention, is pure fabrics or blended fabrics of the regenerated cellulose fibers, or the blended fabrics of the regenerated cellulose fibers and other chemical fibers.

Description

technical field [0001] The invention relates to a dyeing and finishing method of regenerated cellulose fibers / regenerated cellulose fiber fabrics, in particular to a preparation method of silver golden regenerated cellulose fibers / regenerated cellulose fiber fabrics. Background technique [0002] Silver is the metal with the lowest resistivity among all metals, so it has high conductivity and can resist 5000 volts of static electricity. No static comfort, so the silver fiber can conduct static electricity very quickly and efficiently, which can protect the human body from electromagnetic waves, especially for pregnant women, protect the fetus in the abdomen from electromagnetic waves, and ensure long-term work near electromagnetic sources such as computers The health of personnel plays an important role in health care. The mechanism of metal silver sterilization is to block the physiological process of bacteria. Under wet conditions, silver ions can coagulate the proteins ...
