Abstract
The invention discloses a preparation process of a wool-like fabric, which relates to the technical field of artificial fur, and comprises the following steps: s1, warping; s2, knitting; s3, cutting cloth; s4, presetting; s5, soaking and modifying; s6, dyeing; s7, post-finishing; according to the parts by weight, every 100 parts of water contains the following components: 35-40 parts of sericin; tween 801-2 parts; 8-10 parts of epoxy chloropropane; 2-4 parts of sodium hydroxide; and 2-4 parts of a catalyst. The sericin mainly contains amino acid, and has excellent moisture absorption performance because the molecular structure contains hydrophilic groups such as hydroxyl, carboxyl and the like. The method comprises the steps of utilizing an active C-Cl bond in an epoxy chloropropane molecule to perform nucleophilic substitution reaction with an amino group in sericin for condensation, or utilizing the amino group in sericin and a benzene ring in epoxy chloropropane to perform ring opening reaction to prepare a glue-containing epoxy compound, and further utilizing the epoxy chloropropane as a carrier to graft the sericin onto polyester fibers so as to improve the moisture absorption performance of the polyester fabric.

The technical scheme mainly solves the defect that the polyester fiber is easy to generate static electricity, but the polyester fiber has the defects of poor moisture absorption and water retention and stuffy wearing when being used as a garment material, and needs to be improved.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a preparation process of a wool-like fabric, and the polyester fabric prepared by the process can solve the problems of poor moisture absorption and poor water retention property so as to overcome the defect of stuffiness in wearing.
In order to achieve the purpose, the invention provides the following technical scheme:
a preparation process of a wool-like fabric comprises the following steps:
s1, warping: respectively warping the FDY terylene and the DTY terylene;
s2, warp knitting: weaving FDY terylene as surface yarn and DTY terylene as bottom yarn to obtain three-layer gray fabric, wherein two sides are DTY layers and the middle is FDY layer;
s3, splitting: splitting the grey cloth from the middle to obtain two semi-finished fabrics;
s4, presetting: conveying the semi-finished fabric in a tunnel furnace, wherein the heating temperature of the tunnel furnace is 210-220 ℃;
s5, soaking modification: putting the pre-shaped fabric into a dye vat without dye, adding a modifying treatment agent, soaking for 40-60min at the temperature of 80-100 ℃, soaking for two times, rolling for two times and drying;
s6, dyeing, namely putting the modified fabric into a dye vat, adding a dye, soaking and dyeing for 30-60min at the temperature of 110-120 ℃, and drying after dyeing is finished;
s7, after finishing: shaping, brushing, polishing and winding the dyed fabric;
according to the parts by weight, every 100 parts of water, the modified treating agent comprises the following components:
by adopting the technical scheme, the FDY polyester is also called fully drawn yarn, the fabric is smooth and soft in handfeel, the DTY polyester is also called polyester low stretch yarn and has the characteristic of high stability, the FDY polyester is used as the surface yarn to provide a good handfeel and smoothness basis for wool-like, and the DTY polyester is used as the bottom yarn to ensure that the DTY layer has good width stability due to good stability. And the polyester yarn has the characteristics of resisting chemical substances and frequent washing, reducing the fading and decoloring phenomena of the fabric and having extremely high fire resistance.
The three-layer grey cloth is obtained after warping and weaving, and then two semi-finished fabrics are obtained by splitting the grey cloth from the middle, so that the characteristics of the FDY polyester filaments can be effectively utilized to obtain the semi-finished fabrics more efficiently in the production and preparation process.
The FDY terylene has higher content of textile oil on the surface due to the preparation process, so that the FDY layer is softer and more collapsed.
