Problems solved by technology

[0002] Polyester fiber has high strength and elastic recovery ability, so it is durable, wrinkle-resistant and non-ironing, but its hygroscopicity is poor, it is easy to be charged with static electricity, and it is stained with dust, which affects the appearance and comfort; modified polyester is added in polycondensation. The composition of the third monomer, due to the existence of the chemical substance group, it increases the softness, hygroscopicity

Embodiment 1

[0031] The traditional dyeing process and the method of the present invention are respectively used to dye polyester / modified polyester / spandex (80 / 15 / 5) blended fabrics.

[0032] (1) The traditional dyeing process is: pre-setting → pre-treatment → dyeing polyester → cleaning → dyeing modified polyester → cleaning → washing water → dehydration and drying; the process time flow is as follows: figure 1 as shown,

[0033] The dyeing materials are:

[0034] Dyed polyester:

[0035] Disperse dye black SW-R 3%; Glacial acetic acid / (g / L)1; Sodium acetate / (g / L)1; Disperse leveling agent / (g / L)0.5;

[0036] Polyester cleaning:

[0037] Acid cleaning agent / (g / L)2; glacial acetic acid / (g / L)1

[0038] Dyed modified polyester:

[0039] Cationic dye black CA 1%; Glacial acetic acid / (g / L)1; Sodium acetate / (g / L)1; Cationic leveling agent / (g / L)0.5;

[0040] Modified polyester cleaning:

[0041] Cleaning agent / (g / L) 1.5.

[0042] (2) Dyeing process of the present invention: presetting → ...

Embodiment 2

[0059] Use the method of the present invention to dye 80% polyester 20% modified polyester blended+20DPU single jersey.

[0060] The color code is QFL-2 black, and the weight of the fabric is 160g / ㎡;

[0061] Dyeing recipe:

[0062] Disperse Cationic Red CD 0.02%, Disperse Cationic Yellow CD 0.3%, Disperse Cationic CD 0.19%, Disperse Red 4B 0.1%, Disperse Yellow GG 0.2%, Disperse Black S-R 3.3%, Dyeing Pigment 2g / L, Anti-sedimentation Agent 1g / L, acid cleaning agent 2g / L, glacial acetic acid 1g / L.

[0063] The specific dyeing process is:

[0064] (1) Pre-type

[0065] Raise the temperature of the stenter setting machine to 195 ° C ± 2, and control the cloth speed at 20 m / min for pre-setting;

[0066] (2) Dyeing

[0067] Put the knitted fabric into the dyeing vat, add cold water at 40°C±2 to the dyeing vat and control the bath ratio to 1:4-5; add anti-sedimentation agent and dyeing pigment to the dyeing vat in turn, with an interval of 5 minutes; disperse cations Add the...

Abstract

The invention relates to a polyester fiber / modified polyester fiber blended fabric dyeing method. The method specifically sequentially includes the steps such as pre-sizing, dyeing, rinsing, washing and dewatering and drying, which are different from the processes of pre-sizing, pretreatment, polyester fiber dyeing, rinsing, modified polyester fiber dyeing, rinsing, washing, dewatering and dryingin the prior art. Compared with the prior art, the method has the advantages that polyester fiber and modified polyester fiber of fabric are dyed simultaneously by one bath process, the pretreatment is omitted, shading effect after dyeing is good, usage of water and steam in dyeing is reduced greatly, time for dyeing is shortened greatly, and usage of dyestuff is also reduced.

Description

technical field [0001] The invention relates to a dyeing method of textiles, in particular to a dyeing method of a polyester / modified polyester blended fabric. Background technique [0002] Polyester fiber has high strength and elastic recovery ability, so it is durable, wrinkle-resistant and non-ironing, but its hygroscopicity is poor, it is easy to be charged with static electricity, and it is stained with dust, which affects the appearance and comfort; modified polyester is added in polycondensation. The composition of the third monomer, due to the existence of the chemical substance group, makes it increase softness and hygroscopicity. It has improved dyeability, high dyeing rate, high color fastness, wide color spectrum and bright dyeing. The blending of the two fibers is soft, moisture-absorbing, breathable, and has good durability and anti-wrinkle and non-ironing properties. However, the properties of the two fibers are quite different. The traditional dyeing and fin...
