Embodiment 1

[0038] The base fabric is polyester. The warp and weft materials of the base fabric are 1 / 75D / 72f polyester filaments, and the warp and weft density is 580×380 threads / 10cm; the square meter weight is 83g / m 2 .

[0039] Post-processing proceeds as follows:

[0040] (1) Desizing: use an open-width desizing machine. The temperature of the desizing tank is 95°C; the running speed of the fabric is 40m / min.

[0041] The formulation of the treatment liquid, by weight, includes 2.5% caustic soda; 0.45% stabilizer; 0.225% penetrant; 0.225% scouring agent, and the rest is water.

[0042] (2) Base weight reduction treatment: use high temperature and high pressure overflow reduction machine. The bath ratio is 1:18; the treatment temperature is 120°C; the treatment time is 40 minutes, and then washed with water and dried.

[0043] The formulation of the treatment liquid, by weight: 2.5% caustic soda; 0.2% penetrating agent; 0.2% scouring agent.

[0044] The weight reduction rate of th...

Embodiment 2

[0050] (1) desizing: with embodiment 1

[0051] (2) Base weight reduction treatment: use high temperature and high pressure overflow reduction machine. The bath ratio is 1:15; the treatment temperature is 115°C; the treatment time is 43 minutes, and then washed with water and dried.

[0052] The formulation of the treatment liquid, by weight: 2% caustic soda; 0.25% penetrating agent; 0.25% scouring agent.

[0053] The weight reduction rate of the fabric after finishing in step (2) is 10%.

[0054] (3) Padding finishing solution: padding at room temperature. The fabric running speed is 20±1m / min; the drying temperature is 120°C; the baking temperature is 158°C.

[0055] The finishing agent is prepared according to the following formula (parts by weight), including 5 parts of silk peptide; 3 parts of polyethylene glycol; 3 parts of citric acid, 1.5 parts of sodium dihydrogen phosphate, 2 parts of acetic acid, 2 parts of denatured silicone, and 1 part of chitosan share.

Embodiment 3

[0059] (1) desizing: with embodiment 1

[0060] (2) Base weight reduction treatment: use high temperature and high pressure overflow reduction machine. The bath ratio is 1:20; the treatment temperature is 125°C; the treatment time is 37 minutes, and then washed with water and dried.

[0061] The formulation of the treatment liquid, by weight: 3% caustic soda; 0.15% penetrating agent; 0.15% scouring agent.

[0062] The weight reduction rate of the fabric after finishing in step (2) is 12%.

[0063] The finishing agent is prepared according to the following formula (parts by weight), including 7 parts of silk peptide; 5 parts of polyethylene glycol; 5 parts of maleic anhydride, 2.5 parts of disodium hydrogen phosphate, 1 part of acetic acid, 1 part of softening agent, and 0.5 parts of chitosan share.

[0064] The preparation process of the finishing solution is as follows: by weight, dissolve 1 part of acetic acid in 75 parts of water, then add 0.5 parts of chitosan, dissolve...

Abstract

The invention provides a finishing agent for preparing comfortable and cool polyester silk-like fabric and a post-treatment method of the comfortable and cool polyester silk-like fabric, aiming at overcoming the defects of the finishing agent of the polyester silk-like fabric, such as high processing cost and poor durability in the prior art. The finishing agent provided by the invention is composed of the following components in parts by weight: 5-7 parts of silk peptide, 3-5 parts of polyethylene glycol, 3-5 parts of a cross-linking agent, 1.5-2.5 parts of a cross-linking catalyst, 1-2 parts of acetic acid, 1-2 parts of a softening agent, 0.5-1 part of chitosan and the balance of water. The post-treatment method of the polyester silk-like fabric comprises the following steps: desizing, alkali weight reduction treatment of the base fabric, and pad finishing. By utilizing the finishing agent and the post-treatment method in the invention, the defect, such as hard feel, of the polyester fabric is overcome so that the polyester fabric has the advantages of excellent wrinkle resistance and soft feel, and is air-permeable, cool and comfortable to wear.

Description

technical field [0001] The invention relates to a finishing agent for polyester imitation silk fabrics, a preparation method thereof and a post-treatment method for polyester imitation silk fabrics. Background technique [0002] Polyester fabrics have incomparable excellent properties of natural fibers such as high strength, wear resistance, good wrinkle resistance, no insects, quick drying, and easy care. However, it has low moisture regain, poor moisture absorption and vapor permeability, stuffy clothes, easy to generate static electricity, easy to absorb dirt and breed bacteria. Therefore, the wearing comfort of polyester fabric is poor. [0003] The shortcomings of polyester fabrics can be improved by chemical fiber modification technology, and their wearing comfort can be improved. Such as adding hydrophilic monomers or polymers in the process of synthesis and spinning, but this technical operation is difficult and costly. After finishing technology, the hydrophilici...
