Problems solved by technology

[0004] However, a common disadvantage of the silicone finishing agents used for cotton fabrics is that the washability is not good and the hydrophilicity is lost too much due to the customer's pursuit of hand feeling. This is mainly due to the reactive groups between the silicone finishing agents and cotton fibers. It is not strong enough, and the hand feel is obviously reduced after ten times of washing. In addition, the hydrophilic group of the cotton fabric itself is blocked by the silicone finishing agent and loses its effect.

Abstract

The invention discloses a hydrophilic organosilicon finishing agent for cotton fabric and a preparation method thereof and relates to the technical field of textile auxiliaries. The organosilicon finishing agent is prepared from the following components of, by weight, 15%-25% of monochloro monomer, 5%-10% of dichloro monomer, 2.5%-5% of trichloro monomer, 0.5%-1% of cross-linking monomer, 5%-10% of environmentally friendly solvents, 2.5%-5% of mixed emulsifier, and the balance deionized water with the pH is equal to 4-4.5. The hydrophilic organosilicon finishing agent for the cotton fabric andthe preparation method thereof have the advantage that the textile finishing agent better in hydrophilic performance is provided.

Description

technical field [0001] The invention relates to the technical field of textile auxiliaries, in particular to a hydrophilic silicone finishing agent for cotton fabrics and a preparation method thereof. Background technique [0002] Textile auxiliaries are necessary chemicals in the process of textile production and processing. Textile auxiliaries play an indispensable role in improving the product quality and added value of textiles. It can not only endow textiles with various special functions and styles, such as softness, wrinkle resistance, shrink resistance, waterproof, antibacterial, antistatic, flame retardant Etc., can also improve the dyeing and finishing process, play a role in saving energy and reducing processing costs. Textile auxiliaries are crucial to improving the overall level of the textile industry and their role in the textile industry chain. [0003] As a special functional finishing of fabrics, silicone finishing agents are more and more popular among c...
