Description

Technical Field

[0001] The invention relates to the technical field of fabric finishing, and in particular to a fabric finishing liquid based on cationic modified segmented elastic silicone oil and a preparation method thereof. Background Art

[0002] In today's textile market, consumers are increasingly demanding on fabrics, not only pursuing beauty and comfort, but also focusing on functionality and durability. Traditional fabric finishing processes can often only improve performance in a single aspect, and it is difficult to meet diversified needs. For example, fabrics are susceptible to bacterial and fungal contamination during daily use and storage. The breeding of microorganisms not only produces odors, but may also cause health problems such as skin allergies. At the same time, wearing comfort is one of the key indicators for measuring fabric quality. Fabrics with poor softness will give people a rough and stiff touch, affecting the wearing experience, and insufficient hygroscopicity will make it difficult for sweat on the skin surface to dissipate quickly, making people feel stuffy and humid, reducing the wearing comfort of clothing. In addition, during the fabric finishing process and use process, the fabric is affected by light and oxidation factors, and it is very easy to age and yellow, which makes its appearance worse and reduces the added value of the product.

[0003] Therefore, it is of great significance to develop a fabric finishing liquid based on cationic modified block elastic silicone oil and a preparation method thereof that can simultaneously take into account multiple functions such as antibacterial, softening, moisture absorption and anti-aging and yellowing.

[0018] In the process of preparing a fabric finishing liquid based on a cationic modified block elastic silicone oil, a cationic modified block elastic silicone oil is first prepared, and octamethylcyclotetrasiloxane and 1,1,3,3-tetramethyldisiloxane are used as polymerization monomers for polymerization to form a terminal hydrogen silicone oil, and then the terminal hydrogen silicone oil and allyl glycidyl ether react, and the Si-H on the terminal hydrogen silicone oil reacts with the alkenyl on the allyl glycidyl ether to undergo a silylation addition reaction, and an epoxy group is introduced at the same time to obtain a terminal epoxy silicone oil, and then the terminal epoxy silicone oil and polyetheramine are reacted, and the epoxy group on the terminal epoxy silicone oil reacts with the amino group on the polyetheramine to undergo a ring-opening reaction. The block silicone oil is obtained by addition reaction, and 2,4-dihydroxybenzophenone and chloroacetyl chloride are reacted, and the hydroxyl group on the 2,4-dihydroxybenzophenone reacts with the acyl chloride group on the chloroacetyl chloride, and a chlorine atom is introduced to obtain an ultraviolet modifier. Then, the block silicone oil and benzyl chloride are reacted, and the secondary amine group on the block silicone oil reacts with the chlorine atom on the benzyl chloride to reduce the number of secondary amine groups and increase some quaternary ammonium cationic groups. Then, the block silicone oil is reacted with the ultraviolet modifier to further reduce the number of secondary amine groups and increase the quaternary ammonium cationic groups in large quantities, and a benzophenone structure is introduced to obtain a cationic silicone. The cationic silicone oil is treated with isophorone diisocyanate to introduce a large number of isocyanate groups into the molecular structure of the cationic silicone oil to obtain a cationic modified segmented elastic silicone oil; the cationic modified segmented elastic silicone oil can react with the hydroxyl and amino groups on the fabric fiber molecules by using the isocyanate groups on its molecular chain, thereby connecting to the surface of the fabric fiber in the form of chemical bonds to form a tight covering film. The covering film containing a large amount of organic silicon can give the fabric excellent flexibility and elasticity, improve the comfort and wrinkle resistance of the fabric, and the introduced quaternary ammonium cationic groups can effectively improve the hand feel of the fabric. It is endowed with excellent antibacterial and antimicrobial properties, and the formation process of the quaternary ammonium cationic group eliminates a large number of primary and secondary amine groups and introduces a benzophenone structure at the same time. The primary amine group is easily oxidized under the action of light and heat, and the secondary amine group has the effect of synergistically accelerating the oxidation of the primary amine group, promoting the formation of chromophores, and causing the finished fabric to turn yellow. Therefore, under the synergistic effect of reducing the number of primary and secondary amine groups and introducing a benzophenone structure, it is endowed with excellent oxidation inhibition, thereby avoiding yellowing of the fabric during the treatment process, improving its anti-yellowing performance, ensuring the aesthetics of the fabric, and extending the service life of the fabric.
