Problems solved by technology

[0007] The anti-wrinkle finishing liquid method in the prior art generally adopts epoxy-modified polysiloxane emulsion, but the synthesis reaction using common catalysts such as concentrated sulfuric acid and trifluoromethanesulfonic acid has strict requirements on the synthesis conditions, such as raw materials need to carry out high-demand and non-toxic Water drying treatment, the reaction system needs to pass inert gas to isolate the air, etc. If anhydrous and oxygen-free treatment is not carried out, the above reaction system will easily form a gel product between the reactants under the action of the catalyst, because Si-H has a strong Reduction, due to the presence of air and water, it is easy to be oxidized into Si-OH and Si-O-Si bonds at higher temperatures; under the action of a strong catalyst, Si-H may also undergo hydrolysis reaction and hydrolyze into Si-OH , and then condensed into silica gel, unable to achieve effective control of hydrogen content and molecular weight of the target product

Abstract

The invention relates to the field of textile preparation, in particular to a preparation method of a high-elasticity crease-resistant silk shirt fabric. The preparation method comprises the steps of blending, refining, finishing, washing and the like. According to the preparation method of the high-elasticity crease-resistant silk shirt fabric, the high-elasticity crease-resistant silk shirt fabric provided by the invention has a soft and smooth hand feeling, good drapability and elegant feeling, excellent skin fitting property and special pearl-like soft luster; a finishing agent disclosed by the invention contains polysiloxane chain segments, so that the damage to the strength of the real silk fabric after crease-resistant finishing can be weakened or even counteracted, and the whole finishing agent molecules do not contain amino groups, so that the yellowing problem of the real silk fabric after finishing is reduced, and a good crease-resistant finishing effect on the real silk fabric is obtained; and the crease resistance of the finished fabric is improved, the finished fabric has durable crease resistance, softness and hydrophilicity are considered at the same time, and real silk is not damaged.

Description

technical field [0001] The invention relates to the field of textile preparation, in particular to a method for preparing a high-elastic wrinkle-resistant silk shirt fabric. Background technique [0002] Functional fibers use scientific and technological means to modify various natural fibers or chemical fibers. Various fabrics prepared from them have the advantages of good performance and strong functionality, and are favored by many businesses and consumers. [0003] CN101603229A relates to a kind of icy diversified high-grade shirt fabric, which is characterized in that it is made of fine denier bamboo fiber 30%-35%, fine denier polyester 28%-30% and long-staple cotton 35%-40% blended according to weight percentage become. The three kinds of fiber raw materials are all environmentally friendly products. Through the ingenious combination, the strength of the yarn is improved, and it has the incomparable characteristics of other fabrics-good moisture absorption, perspirati...
