Problems solved by technology

For example, CN102465403A discloses a novel finishing process through a copolymerized fluorine-based anti-fouling and easy-to-decontamination finishing liquid. The finishing liquid is formed by a fluorine-based anti-fouling and easy-to-decontamination finishing agent, a fluorine reinforcing agent, an anti-gelling agent, and a softener. , this process has improved oil repellency, water repellency, and easy decontamination; another example is Nissin Textile Co., Ltd. in CN200710086215. Double-layer structure, through hydrophilic and anti-fouling processing on the surface material, and hydrophobic and anti-fouling processing on the adhesive lining, the fiber structure is endowed with both anti-fouling and easy decontamination functions, but this method is relatively complicated and is mainly used for collars part
Although the above two applications have solved the problem of easy decontamination, the problem of water absorption still exists, which will affect the wearing comfort

Abstract

The invention discloses a water-absorbing oil-repellent fabric and its production method. The surface of single filaments of the fabric is attached with a resin layer which is mainly composed of polyester resin and fluoroplast. Positive and negative surfaces of the fabric have characteristics as follows: in the initial stage, water absorption is less than 5 seconds, oil repellency is above level 6, and easy decontamination performance is above level 4. The production method is simple and easy to operate. Base cloth firstly undergoes hydrophilic resin bath treatment, and then, oil-repellent easy-decontamination resin padding treatment is carried out. The obtained fabric has oil-repellent easy-decontamination functions, has excellent water absorption, has excellent washing endurance, and can be widely used in production of shirts, working clothes and the like.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a water-absorbing and oil-repellent fabric, in particular to a water-absorbing and oil-repellent fabric with water absorption, oil repellency and easy decontamination properties on both front and back sides. Background technique [0002] With the development of society and the improvement of living standards, consumers' requirements for clothing are no longer simply satisfied with keeping warm, concealing shame, and being beautiful, but prefer a variety of functional clothing. The functional requirements mainly focus on water absorption, moisture permeability, oil repellency, antifouling, and easy decontamination. In order to meet the high demands of consumers, some textiles with multiple functions are being actively developed and researched. [0003] Initially, people generally endow the fabric with waterproof and oil-repellent function by resin coating on one side of the base f...
