Embodiment

[0020] Fabric fabric: width 175cm, density 155g / m 2 .

[0021] The pretreatment process of the bio-based material-based memory T400 fabric of the present invention includes the first open-width desizing process, the cold pad-batch process and the second open-width desizing process in sequence.

[0022] In the first step, an open-width desizing machine is used to carry out the first open-width desizing treatment on the gray fabric. The formula of the desizing aid used in the first open-width desizing process is as follows:

[0023]

[0024] The temperature condition of the first open-width desizing process is 98° C., and the vehicle speed is 55 m / min.

[0025] In the first open-width desizing process, TF-127B oxidative desizing agent has good alkali resistance and stability under hot alkali conditions at 98°C, and can weave chemical fiber fabrics into commonly used polyacrylate pulp The ester bond in the macromolecule of the material is oxidized and decomposed to become a ...

Abstract

The invention discloses a pretreatment process for a memory T400 fabric based on a biological based material. The pretreatment process comprises a first open width desizing process, a cold rolling process and a second open width desizing process which are carried out in sequence, wherein a desizing aid used in the first open width desizing process has a formula of a 50-60g / L liquid caustic soda, a1-2g / L long-vehicle rapid desizing agent TF-127B, a 1-2g / L emulsification refining agent, a 0.5-0.7g / L oil remover SB-101 and 1-2g / L melamine phosphate; a rolling treatment liquid used in the cold rolling process has a formula of a 80-90g / L liquid caustic soda, a 1-2g / L long-vehicle rapid desizing agent TF-127B, a 1-2g / L emulsification refining agent, a 0.5-0.7g / L hydrogen peroxide and 1-2g / L melamine phosphate; a desizing aid used in the second open width desizing process has a formula of a 30-40g / L liquid caustic soda, a 1-2g / L long-vehicle rapid desizing agent TF-127B, a 1-2g / L emulsification refining agent and 1-2g / L ammonium triphosphate. By adopting the pretreatment process, an appropriate pretreatment process is made, various impurities on a fabric can be removed, smooth later dyeing procedures can be ensured, and the softness of the fabric can be also ensured.

Description

technical field [0001] The invention relates to a pretreatment method before textile dyeing, in particular to a pretreatment process of memory T400 fabric based on bio-based materials. Background technique [0002] Bio-based PTT fibers use glycerin, glucose or starch as raw materials to produce 1,3-PDO polymerized monomers through microbial fermentation, and then form macromolecular slices by PTA direct esterification, and then prepare PTT long fibers by melt spinning. silk or staple. Noodles with PTT as the main body have soft touch, good deformation memory and drapability. [0003] T400 fiber is a patented product developed by INVISTA, a subsidiary of DuPont. It is made of two polyester fibers, PTT and PET, through side-by-side composite processing. Due to the different microscopic structures of the two components, after heat and humidity treatment, the fibers will produce different degrees of Shrinkage makes it produce strong longitudinal stress and twist away from the ...
