Problems solved by technology

However, the strength of acetate filament fiber is low, and the elongation at break is relatively large. Generally, blending is used to form acetate fiber blended fabrics with moderate strength and the advantages of acetate filament fibers, such as acetate fiber and polyester fabric.
[0003] Acetate fiber and polyester in polyester fabric are synthetic chemical fibers with poor dyeing performance, while acetate fiber has many voids inside and relatively good dyeability. The color fastness of products obtained through conventional dyeing and finishing processes is low, which restricts the use of acetic acid. Marketing of fiber and polyester fabric

Embodiment 1

[0057] This application discloses a dyeing and finishing process of acetate-polyester double-layer georgette fabric. The dyed fabric in this application is acetate-polyester double-layer georgette, the specification is 75D+30D / SSY+75D+30D / SSY, and the blank factory is Haiyanjia Source Color Technology Co., Ltd., with a door width of 147cm and a weight of 240g / m 2 .

[0058] The dye used in this example is Charlene Yellow ECF-NEW, the dosage is 1% (owf), and the dyeing and finishing auxiliaries used include JY208L, JY406EA, HAC, JY leveling agent, and phosphorus-free chelating dispersant ZS-558 . The concentration of dyeing and finishing auxiliaries in this implementation is: 1.0g / L of HAC, 1.0g / L of JY208L, 0.4g / L of JY406EA, 0.8 / L of phosphorus-free chelating dispersant ZS-558, 1.0g / L The JY leveling agent.

[0059] A kind of dyeing and finishing process of double-layer georgette fabric of acetate polyester comprises the following steps:

[0060] Step 1, using an unwindin...

Embodiment 2

[0077] The difference between Example 2 and Example 1 is that the dyeing formula 1 in Example 1 is replaced by dyeing formula 2: the target dyeing is red, and the amount of Yingcai clone DRA-2B red used is 0.5%.

Embodiment 3

[0079] The difference between Example 3 and Example 1 is that the dyeing formula 1 in Example 1 is replaced by dyeing formula 3: the target dyeing is blue, and the amount of Yingcai clone DRA-3G blue used is 2%.

Abstract

The invention relates to the technical field of fabric dyeing and finishing, in particular to a dyeing and finishing process of a polyester acetate double-layer georgette fabric. The dyeing and finishing process of a polyester acetate double-layer georgette fabric comprises the following steps of step 1, unwinding gray fabric; step 2, pretreatment; step 3, setting and leveling; step 4, gray fabric dyeing: raising the water temperature to 40-50 DEG C, running for 8-10 minutes, adding a dyeing and finishing aid, running for 10-20 minutes, adding glacial acetic acid, running for 10-20 minutes, adding a disperse dye, running for 10-20 minutes, fixing color, raising the temperature to 100-110 DEG C, keeping the temperature for 40-60 minutes, discharging water, washing with a 0.2-0.6 g / L reducing agent, raising the temperature to 85-95 DEG C, keeping the temperature for 10-20 minutes, cooling, soaping and discharging water; and step 5, softening, overfeeding and setting to obtain a finished product. The polyester acetate double-layer georgette fabric has the advantages of being comparable to real silk in hand feeling, soft, silky, uniform in color and luster and good in color fastness.

Description

technical field [0001] The application relates to the technical field of fabric dyeing and finishing, in particular to a dyeing and finishing process of acetate-polyester double-layer Georgette fabric. Background technique [0002] Acetate fiber is a kind of acetate filament fiber that can be used for spinning and weaving through chemical synthesis from wood pulp fiber extract and acetic anhydride as synthetic raw materials. Acetate filament fiber has good thermoplasticity and formability, and has good drape, antistatic and anti-moth. Therefore, fabrics using acetate filament fiber have good moisture absorption, breathability, resilience, and antibacterial properties. , can not afford static electricity and hair balls, skin-friendly and comfortable. However, the strength of acetate filament fiber is low, and the elongation at break is relatively large. Generally, blending is used to form acetate fiber blended fabrics with moderate strength and the advantages of acetate fila...
