Problems solved by technology

In the past, compounds containing long fluorocarbon chains were mostly used as water-repellent finishing agents to obtain fabrics with low surface free energy, but such finishing agents are expensive, and some studies have found that fluorine-containing chemicals are difficult to biodegrade, so they are harmful to the environment and human body. potential health hazard
In addition, due to the poor compatibility between the hydrophobic finishing agent of the fluorine-containing system and other functional finishing agents, the formulated working solution is unstable. If the commonly used hydrophobic finishing agent is simply added to other functional coating agents, it will eventually lead to its The coverage with the coating agent components is also poor, so the functional effects such as water repellency of the fabric are poor

Abstract

The invention provides a post-finishing technology of a luminous water-repellent polyester fabric, and belongs to the technical field of textiles. The post-finishing technology of the luminous water-repellent polyester fabric comprises the steps of pretreatment, water-repellent finishing, luminous coating preparation, coating, dipping, rolling, drying and the like. The technology further comprisesthe step of coating under the action of ultrasonic waves after a luminous coating is prepared. The finally prepared fabric has a good luminous function and good water-repellent performance; meanwhile, the technology is environmentally friendly, so that the prepared fabric has relatively good market prospects.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a post-finishing process for luminous water-repellent polyester fabrics. Background technique [0002] With the rapid development of economy and society, single-function textiles can no longer meet people's needs, and multi-functional textiles are more and more popular because of their excellent performance. [0003] Glow in the dark means that it can glow in the dark, and luminous fabrics can produce light in the dark. It is a new type of technological fabric. Because it is visible in dark environments, luminous fabrics can play a warning role in the dark, and can also be used as markers to guide people. Therefore, they are widely used and are mainly used in transportation, clothing, construction industries and other fields. [0004] In the prior art, the production process of luminous fabrics is disclosed, mainly by modifying the yarn during the spinning process, so as to giv...
