Problems solved by technology

However, at present, there is little research on the development of hydrophilic and oleophobic fabrics. The preparation technology and products still have complex methods, lack of effective cross-linking between molecules in the coating, water droplets spreading not fast enough, and oleophobicity are not strong enough.

Abstract

The invention discloses a multifunctional polyester fabric and a preparation method thereof. The multifunctional polyester fabric is prone to water absorption, water drop spreading time is 1 second minimally, the fabric has super-oleophobicity on soybean oil, a contact angle of the soybean oil is kept at 150 degrees or above, soybean oil on the fabric surface can be removed by gentle flushing withclear water or soaking in clear water, and the fabric is excellent in antistatic performance. The preparation method includes steps: uniformly coating the surface of the polyester fabric with solution containing a photoinitiator, a cross-linking agent, a photoactive hydrophilic monomer and an oleophobic monomer; exposing the coated fabric under ultraviolet light. The multifunctional polyester fabric has advantages that oil resistance is realized, moisture absorbing, sweat permeation and antistatic efficacies beneficial to comfort in wearing are achieved, and an extremely high practical valuein the field of functional textiles is achieved.

Description

technical field [0001] The invention belongs to the field of functional fabrics, and in particular relates to a multifunctional polyester fabric and a preparation method thereof. Background technique [0002] Polyester is an important variety of synthetic fibers and is the trade name of polyester fibers in my country. Polyester accounts for more than 60% of the world's synthetic fiber production, and is widely used in textiles such as clothing, bedding, and various decorative fabrics. Although polyester fabric has the characteristics of high strength, good wear resistance, good heat resistance, and low price, making it one of the most commonly used fabrics in textiles, polyester fabric has poor hygroscopicity and feels stuffy when worn, which affects the comfort of wearing. Comfortable, while polyester fabrics are easy to carry or generate static electricity, which will cause a large amount of dust adsorption in the air. The traditional modification of polyester fabrics is...
