Problems solved by technology

[0002]Traditional printing and dyeing pretreatment is mostly high-temperature steaming, desizing, scouring, and bleaching all require high-temperature washing or high-temperature cooking, high energy consumption, low efficiency, and pollution discharge big
The emerging cold pad-batch technology is to stack alkali, hydrogen peroxide, stabilizer, refining agent and other additives at room temperature, and then perform pretreatment by high-temperature water washing. The stacking time is generally about 20 hours, the efficiency is low and the production cycle is extended; in addition, because the amount of semi-finished products left in the stack is huge, generally around 70,000 meters, if there is a quality problem, it will cause huge losses

Embodiment 1

[0011] Specifications: Polyester-cotton blended T65 / C35 40×40 110×90 63″

[0012] The technological process of the present invention: cloth turning → seaming → singeing → low temperature deboiling and bleaching → hot water washing

[0013] (1) Singeing process:

[0014] Singeing is performed with a 3400 mm double-live mouth singeing machine from Osdorf, Germany. Singeing machine speed: 110±2 m / min; wind pressure: 13±1 mbar; burner: facing each other (one positive and one reverse); gas pressure: 0.11±0.01Mpa; drying steam pressure: 0.10±0.05Mpa; fire extinguishing Steam box pressure: 0.02±0.01Mpa; paddle car pressure: 0.3±0.05Mpa; tension frame pressure: 0.4±0.1Mpa; singeing level: 4 and above.

[0015] The prescription of the low-temperature descouring and bleaching working solution: stabilizer P-CBB 2g / L, substitute alkali DA-GS710 2.5g / L, NaOH 10g / L, cold pile king HLD 6g / L, sodium tripolyphosphate 2g / L, Sodium hydrosulfite 10g / L, hydrogen peroxide activator H2SO4 0.1g / L,...

Abstract

The invention relates to a printing and dyeing process comprising the steps of cloth-turning, sewing, singeing, and low-temperature desizing, scouring and bleaching. The printing and dyeing process is characterized by comprising the following particular steps of: rinsing to remove attachments on the surface of a woven fabric after the steps of cloth-turning, sewing and singeing; then squeezing the woven fabric via a padder and then padding the woven fabric into a working solution; then padding the woven fabric via a feeding padder; then finishing pre-treatments of desizing, scouring and bleaching by piling up for 40-55 minutes at a temperature of 40-50 DEG C; and then washing out reaction residues by using hot water. The printing and dyeing process has the characteristics of high efficiency, good pre-treatment effect, small damage to fiber, high quality of treated fabrics and soft hand feeling and can greatly reduce the pre-treatment energy consumption and shorten the production cycle.

Description

technical field [0001] The invention relates to a textile printing and dyeing process, which belongs to the printing and dyeing treatment technology. Background technique [0002] Traditional printing and dyeing pretreatment is mostly high-temperature steaming treatment. Desizing, scouring, and bleaching all require high-temperature water washing or high-temperature cooking, which leads to high energy consumption, low efficiency, and large sewage discharge. The emerging cold pad-batch technology is to stack alkali, hydrogen peroxide, stabilizer, refining agent and other additives at room temperature, and then perform pretreatment by high-temperature water washing. The stacking time is generally about 20 hours, the efficiency is low and the production cycle is extended; in addition, because of the huge amount of semi-finished products left in the stack, generally about 70,000 meters, if there is a quality problem, it will cause huge losses.
