Description

Multifunctional textile and its manufacturing method and use

The present invention relates to a multifunctional textile and its manufacturing method and use, especially a special process that combines incompatible water repellent and flame retardant to form a highly water repellent, decontamination, oil and mildew resistant and Unique multifunctional textile with excellent flame retardancy and its manufacturing method and use.

according to! With the rapid development of science and technology and the continuous progress of material science, people are gradually becoming highly aware of their own safety and property protection. How to properly protect their important items and avoid irreversible consequences when accidents occur is also important for consumers to buy products today. One of the considerations is that currently, flame retardant materials are widely used. Whether it is building materials, fabrics, plastic products or home appliances, the flame retardant mechanism is added to prevent financial damage from being burned by fire in accidents, which can bring greater protection and protection to users. Safety in use, therefore, many related manufacturers have begun to develop related products.

Traditional flame retardant mechanisms are used in textiles, usually flame retardants are coated on textiles or yarns. However, most flame retardants currently do not have good adhesion to textiles. Therefore, they are formed by direct coating. The flame-retardant textiles are easily washed and dissolved by water when they are washed. Moreover, in recent years, many consumers have gradually paid attention to the water repellent effect of textile products, hoping to make textiles waterproof, stain resistant, and oil resistant. The existing water repellent The main purpose of the agent is to fill the surface of the object with fine chemical substances to fill the surface pores, so that water, oil or other dirt cannot adhere to form a water repellent effect, but it is also the result that most water repellents cannot be added with flame retardants. The existing waterproof and moisture-permeable coatings and fire-retardant coatings are chemically resistant to each other in the processing procedures. If you want to maintain a good spinning and moisture-permeable effect on textiles, most of them need to add water repellent Processing, most of the existing water repellents are mainly fluorocarbon additives, which contain carbon elements that can support combustion. In the process of flame retardant coating, the addition of flame retardants will reduce the adhesion of the water repellent. Therefore, it is necessary to It is quite difficult to add water-repellent and flame retardant to textiles. Most of the existing manufacturers make flame-retardant water-repellent textiles by adding the flame retardant directly to the yarn before weaving to form textiles. After adding the coating water repellent agent, the flame retardant in the yarn has penetrated into the interspace of the yarn, which often causes the water repellent agent to have low adhesion, which is easy to be washed or dissolved.

Therefore, if it is necessary to add flame retardant and water repellent to the fiber at the same time and have continuous and effective functionality, it is relatively difficult to use the general traditional manufacturing process. Therefore, relevant industries use spun water PU resin and brominated fire retardant , Wax smoothing agent... and other materials are stacked with multiple layers to produce waterproof and flame retardant effects. Although water repellent and flame retardant can be added at the same time to achieve the effect of waterproof and flame retardant, the processing procedure is complicated and the effect is limited. After washing This may cause the fire-proof and flame-retardant effect to be greatly reduced; in addition, a related industry has developed a fire-proof and waterproof composite fabric structure, which includes a load-bearing layer made of polyester fiber and a barrier made of modified polyacrylonitrile fiber. The flame-retardant layer and the waterproof layer made of polyethylene are mainly made of polyacrylonitrile fiber by pre-processing to make the flame-retardant cotton layer. However, the alkali resistance of polyacrylonitrile fiber is poor. Using alkaline cleaning products, it is easy to destroy the polyacrylonitrile fiber structure, and the polyacrylonitrile fiber is easy to soften at 190℃~230℃, and it is not easy to handle in the fabric processing. In view of this, if it can be mass-produced with a high degree of flexibility Synthetic fibers with water, flame-retardant, mildew-proof, antibacterial effects, easy to dye, good elasticity, and stain-resistant and washable have become a major issue for the current fiber textile processing industry.

For this reason, the inventor carefully studied the creative spirit of creation. Based on the above technical problems, we started research and development.
