Description

Preparation method of antibacterial anti-static fabric
The technical field is as follows:
the invention belongs to the technical field of functional fabric production, and particularly relates to a preparation method of an antibacterial and anti-static fabric.
Background art:
the polyester fiber is used as the most widely applied chemical fiber, has good fiber forming performance and mechanical performance, high strength, good light resistance, heat resistance and acid and alkali resistance, good processability and spinnability, and can be spun, blended and interwoven. The terylene fabric is washable, wear-resistant, non-ironing and anti-wrinkle, and is widely applied to the fields of clothes, home textiles, decoration, products and the like. However, the polyester fiber has the defects of poor hygroscopicity, no sweat absorption of fabrics, stuffy feeling in wearing, poor dustproof capability, easy dirt contamination and the like, so that the application and the development of the polyester fiber are greatly restricted. In order to improve the wearing comfort of the polyester fiber and the application added value of the polyester fiber, the polyester fiber is generally improved in the aspects of chemistry or physics, so that the polyester fiber is endowed with higher moisture absorption and sweat releasing performance, and the wearing comfort of the polyester fabric is improved. For example, the chinese patent cn201910534743.x discloses a moisture-absorbing, sweat-releasing and antibacterial polyester fabric, which is obtained by desizing, dyeing and padding a grey fabric with a textile auxiliary agent; the grey cloth is formed by blending and weaving the following raw materials in parts by weight: 40-60 parts of polyester fiber; 7-11 parts of viscose; 2-4 parts of regenerated cellulose fiber; desizing, dyeing and padding a textile auxiliary agent by using gray fabric to obtain a polyester fabric with moisture absorption, sweat releasing and antibacterial properties; the grey cloth is made by blending polyester fiber, viscose fiber and regenerated cellulose fiber, and the air permeability, moisture absorption, antistatic property and ultraviolet resistance of the fabric are improved by adding the viscose fiber; the moisture absorption, ventilation and antibacterial properties of the fabric are improved by adding the regenerated cellulose fiber; chinese patent CN201922215378.4 discloses an antibacterial and breathable polyester fabric, which comprises a fabric main body, a first polyester fabric layer, a milk silk fabric layer, a nylon layer, a bamboo fiber fabric layer, an antistatic layer, a second polyester fabric layer and a colored cotton fiber fabric layer. The utility model discloses the design of dacron precoat one and dacron precoat two has improved the crease resistance and the shape preserving nature of surface fabric main part, the gentle smoothness of emulsion surface fabric layer, the antibacterial of surface fabric main part has further been improved, skin affinity, the compliance, the gas permeability etc, the design on nylon layer has improved the dirt resistance and the wearability of surface fabric main part, the sweat-absorbing effect of surface fabric main part has been improved simultaneously, the design on post fine fibre precoat has improved surface fabric main part mould proof mothproof antibacterial effect, the design on antistatic backing has improved the antistatic effect of surface fabric main part, the probability of static appears in the surface fabric main part has been reduced, and then the travelling comfort that the surface fabric main part used has been improved, the design on various cotton fiber precoat has improved the slim and graceful of surface fabric main part, ventilative and cold-proof effect. However, the fabrics in the prior art do not have the functions of dust prevention and static electricity prevention.
The dustproof clothing is protective clothing for protecting relevant operators from being damaged by dust pollution, and is applied to industries such as mines, building materials, chemical industry, metallurgy, food, medicine, military industry and the like.
Static electricity is a static or non-flowing charge (a flowing charge forms a current). Static electricity is formed when charges are accumulated on an object or a surface, and the charges are classified into two kinds of positive charges and negative charges, that is, the static electricity phenomenon is also classified into two kinds, i.e., positive static electricity and negative static electricity. When positive charges are accumulated on a certain object, positive static electricity is formed, and when negative charges are accumulated on a certain object, negative static electricity is formed, but no matter the positive static electricity or the negative static electricity is, when an object with static electricity is contacted with a zero potential object (a grounding object) or an object with a potential difference, charge transfer can occur, and the phenomenon of spark discharge is seen in daily life. For example, in winter in the north, people are easy to be charged with static electricity, and when people contact with other people or metal conductors, the phenomenon of discharge can occur. People can feel the acupuncture feeling of electric shock, and sparks can be seen at night, which is the reason that chemical fiber clothes and human bodies rub to bring positive static electricity. At present, the anti-static fabric is only used on work clothes, and most of polyester fabrics are not suitable to be worn as underwear in a mode of embedding conductive fibers, so that the development of the anti-bacterial and anti-static fabric is very necessary.
