Problems solved by technology

However, this kind of finishing agent also has certain disadvantages, such as high price, easy to pollute the environment, yellowing of the fabric, and serious damage to the strength of the fabric.
[0006] The fabric treated with anti-wrinkle finishing agent endows it with elasticity and resilience, but the handle becomes stiff and rough, the surface of the fabric is rough, affected by external friction and other factors, it is more prone to pilling
However, the fabric treated with the anti-pilling finishing agent cannot increase the wrinkle recovery force of the fabric, and the anti-wrinkle effect and the anti-pilling effect cannot be achieved at the same time.

Abstract

The invention discloses a composite crease-resistant and pilling-resistant finishing agent which comprises, in weight percent, 10-20% of hydrogen-containing silicone oil, 2-5% of sorbitan fatty acid ester, 2-4% of secondary alcohol ethoxylate, 10-20% of acid anhydride, 0.2-0.5% of initiating agents, 6-12% of polydimethylsiloxane, 5-10% of polyglycidyl ether, 2-4% of polyoxyethylene sorbitan fattyacid ester, 0.5-1% of diethylene glycol monobutyl ether, 0.5-2% of polyvinyl alcohol and the rest deionized water. Active Si-H bonds in the hydrogen-containing silicone oil and high-electron-withdrawing acid anhydride are synthesized into copolymers through free-radical addition mechanisms under the action of the initiating agents, esterification reaction among the copolymers and hydroxyl on fibermacromolecules can be achieved, crease-resist effects can be acquired, and softness effects can also be acquired. The copolymers and pilling-resistant finishing liquid are synergistically compounded,a soft and toughened thin film is formed on the surfaces of fibers, sliding of the fibers is reduced, so that fiber ends are adhered onto yarns, plush is not easily formed by friction, the pilling resistance of fabrics is effectively improved, and the composite crease-resistant and pilling-resistant finishing agent is prepared.

Description

technical field [0001] The invention relates to the technical field of textile auxiliaries, in particular to a composite anti-wrinkle and anti-fluff treatment agent and a preparation method thereof. Background technique [0002] During the wearing process of the fabric, due to the factors of the fabric itself and various external forces and external frictions, it is easy to produce wrinkles and pilling before obvious damage occurs, which affects the appearance and wearing performance. Therefore, it is necessary to carry out anti-wrinkle and anti-pilling finishing on the fabric to improve the wearing comfort and quality of the fabric. [0003] The anti-wrinkle and anti-pilling treatment currently on the market is basically completed in two steps, one is anti-pilling finishing, and the other is anti-wrinkle finishing. There are many kinds of additives used, the process is complicated, and the cost is high. [0004] In addition, the breaking strength, elongation at break, and...
