Description

Technical Field

[0001] The invention relates to a flame retardant textile slurry and a preparation method thereof, in particular to a high-performance multifunctional antistatic green flame retardant textile slurry and a preparation method thereof, belonging to the field of textile material modification. Background Art

[0002] During the process of weaving yarn into cloth, the loom will stretch, bend, rub and other repeated mechanical actions on the yarn. Therefore, the yarn must be strong enough to avoid pilling or even breakage during the weaving process, which will affect the quality of the grey cloth. Textile sizing is a modern technology for processing different fiber fabrics such as cotton, linen, wool, silk and chemical fiber. The purpose of sizing is to increase the hardness and strength of the fiber fabric, improve the feel, sliding and naturalness of the fabric, and prevent shrinkage, prevent fiber rupture, and enhance the wear resistance and durability of the fabric. In recent years, with the rapid development of the textile industry, more and higher requirements have been put forward for the performance of sizing materials. Not only are sizing materials required to have traditional properties, but also new requirements such as antistatic, antibacterial and flame retardant have been put forward. However, giving sizing materials the above new properties often increases the difficulty of sizing and makes the sizing process complicated. Therefore, developing a high-performance multifunctional textile sizing agent that is antistatic, flame retardant, wrinkle-resistant, wear-resistant, weather-resistant, and high-strength, and maintaining or simplifying its original sizing process conditions so that the sizing agent can fully penetrate into the fiber, ensure uniform sizing of the yarn and prevent it from breaking easily, and make the surface of the fabric achieve uniform hardness and strength, is of great practical significance and is also a hot topic of research in this field.
