Embodiment Construction

[0014] 1. Fabric sample:

[0015] 70 / 30 modal / polyester blend fabric. The warp and weft yarn count is 45×45, the warp and weft density is 133×72 threads / inch, and the fabric blank is 47 inches.

[0016] 2. The singeing process is two fronts and two reverses, the machine speed is 110-130m / min, and the cloth surface finish is required to be above grade 3.5.

[0017] 3. Desizing

[0018] Prescription (g / L)

[0019] 7658 Amylase 2~4

[0020] NaCl 5

[0021] The process is: hot water padding at 65-70°C → padding with enzyme solution at 55-60°C → stacking at 45-50°C for 4 hours → full hot water washing.

[0022] 4. Bleaching

[0023] Prescription of bleach solution (g / L)

[0024] Hydrogen peroxide 4~8

[0025] OL 4~6

[0026] Stabilizer 4

[0027] Water glass to adjust pH to 10.5

[0028] Bleaching process: padding with bleaching solution → steaming at 95+2°C for 45-60 minutes → fully washing → drying.

[0029] 5. NaOH causticizing treatment

[0030] Treatment solution ...

Abstract

The present invention relates to a dyeing and finishing process of model fibre and polyester fibre blended fabric, and its technological process includes the following steps: singeing, desizing, bleaching, NaOH causticizing treatment, setting, dyeing or printing and after-finishing, and the formula of treatment liquor for making causticizing treatment includes NaOH 40-50 g / L and penetrating agent 1-2 g / L, and the condition of NaOH causticizing treatment is as follows: padding causticizing treatment liquor at normal temperature, depositing for 30-40 min at normal temperature, fully washing with hot water with 80-90 deg.C to neutrality and drying. On the premise of no damaging fibre, as compared with the fabric which is not undergone the process of causticizing treatment the colour yield of said invented fabric can be raised by 20%-50%.

Description

technical field [0001] The invention relates to a fabric dyeing and finishing process in textile printing and dyeing production, in particular to the dyeing and finishing process of modal / polyester blended fabrics. Background technique [0002] Modal fiber is a regenerated cellulose fiber with high strength and high wet modulus, which can be blended or interwoven with other fibers to produce knitted or woven fabrics for clothing, towel socks, bedding, etc. There is no special technical requirement for the dyeing and finishing of modal fiber fabrics. It has strong adaptability to equipment, good dyeing performance, high color yield, bright and bright color, smooth and soft hand feeling, and flat and drape appearance. [0003] In the prior art, the dyeing and finishing process used in the dyeing and finishing process of Modal / polyester blended fabrics is: singeing→desizing→bleaching→setting→dyeing or printing→finishing. However, under the conditions of the above process, the ...
