Background technique

With the development of science and technology and the strengthening of health concepts, people gradually have new requirements for home textile products, from the pursuit of softness and comfort, moisture absorption and breathability to the realization of functions such as anti-mite and deodorant. Home textile fabrics usually have the characteristics of large area and inconvenient cleaning. Therefore, in recent years, people require home textile fabrics to have certain oil and water resistance. In addition, home textile fabrics should also be protected against sudden fires. It has a certain flame retardant effect to prevent the expansion of fire and reduce the loss of human life and property.

In response to the new requirements of home textile fabrics, the existing common methods are to use the method of secondary finishing to improve the oil and water resistance of home textile fabrics, and use the dipping method to attach finishing agents with certain functional properties to the fabric fibers or the surface of the fabric. . Water-repellent finishing is to endow the fabric with the function of water repellency. After the fabric is water-repellent, the surface properties of the fiber are changed, so that the hydrophilicity of the fiber surface becomes hydrophobic, and the water droplets roll on the surface of the fabric without wetting, preventing water droplets from entering from the outside of the fabric. internal. Antifouling finishing is the effect of reducing the accumulation of dirt by changing the surface state of fabric tissue and fibers. However, the existing finishing agents still have the disadvantages of poor compatibility with fibers or fabrics and weak bonding. The shedding of the finishing agents may endanger the health of users. The use of existing finishing agents will reduce the quality of home textiles to a certain extent. The soft comfort of fiber fabric. The finishing agents used in home textile fabrics do not have the functions of waterproof, oil-proof, antibacterial, and flame retardant at the same time.

To this end, make full use of the skin-friendly and soft properties of natural fibers, blend them with synthetic fibers, and carry out modification and finishing during the blending process, so that the finishing agent can be tightly combined with the fibers to improve the waterproof, oil-proof, and flame-retardant effects of the fibers. Weaving fibers into fabrics again has practical value in meeting the application requirements of home textile fabrics.
