Abstract
The present invention discloses a pretreatment process for dyeing fabrics. Said pretreatment process successively includes the steps of width-opening process and enzymatic impregnation process.
Description
Technical field:
The invention belongs to this technical field of pre-treatment process of dyeing knitted fabric, especially belong to enzyme and carry out this technical field of pre-treatment.
Background technology:
The technology of carrying out pre-treatment with enzyme is usually used in the cold rolling heap technology of shuttle-woven fabric, but runs into following problem in the biology enzyme processing procedure of knitted fabric: knit fabric easily produces quality problems such as crease in the middle of cold rolling heap; Because cold rolling heap Technology Need carries out stacking in 3～6 hours to the lining after cold rolling, thereby has taken the time, and needs large-area place to stack, take that plant area is excessive to be unfavorable for large-scale production; If adopting conventional dye vat handles the lining biology enzyme, owing to be the rope form mode, in dyeing course, make the overtension of lining, and in cloth storage trough, can not fully launch to make lining in processing procedure, can't obtain uniform treatment from the inside to surface, make follow-up dyeing very easily produce look flower, problems such as folding line.Chinese patent (publication number: CN1417402A) disclose a kind of operation of knitted fabric being carried out pre-treatment with enzyme, this operation has the hydrogen peroxide preliminary treatment, washing, the biology enzyme maceration enzyme is handled, go out enzyme, washing batch process finished the pre-treatment of knitted fabric, and this kind process water amount is big, and bath raio is 1: 10-50, the operating procedure complexity can not be produced continuously simultaneously.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of water saving, pre-treatment process that can the quantity-produced dyeing knitted fabric.
The technical scheme of technical solution problem of the present invention is: a kind of pre-treatment process of dyeing knitted fabric is followed successively by open-width process, biology enzyme impregnation process process.
Described biology enzyme impregnation process process, biology enzyme 1～2g/l, bleeding agent 1～2g/1, it is 1: 5.5～6.5 that knitted fabric and enzyme are handled bath raio; Temperature: 55 ℃～95 ℃, time 30min～50min.
Described knitted fabric is applicable to cotton or polyester-cotton blend, comprises interlock fabric, plain, flannelette, T-shirt lining.
Described enzyme is by alkaline pectase, cellulase, a kind of or several combinations of protease.
When dying light pre-treatment, also can add hydrogen peroxide simultaneously.
When dying the bleaching pre-treatment, also can add brightening agent and hydrogen peroxide simultaneously.
Fabric can be according to the whiteness requirement in above-mentioned processing procedure, and appropriateness is adjusted various enzymes, hydrogen peroxide, brightening agent consumption, to reach different whiteness effects.
The present invention is preposition by open-width, lining is launched fully, be implemented in the cloth storage trough and fully contact with solution, strengthened the uniformity that biology enzyme is handled lining, cylinder body is reduced to minimum level to the frictionally damage and the tension force of lining, and product dyeing once success rate rose to 98% by 95% of the past.
The present invention has compared with prior art reduced temperature, the bath raio of enzyme impregnation process process.The wet cloth that enzyme was handled can directly dye, and has improved production efficiency.
The specific embodiment:
Embodiment 1: 1 ton of cotton eyelet fabric, specification 21S/1.Color: root of Dahurian angelica cyan
Open-width: the eyelet fabric open-width is become door width of cloth 210cm.
Biology enzyme impregnation process process: advance the cloth water inlet, bath raio: 1: 6, cellulase 6KG, bleeding agent 6KG, 55 ℃ of temperature, time 30min discharges water, dyeing.
Through the fabric of above-mentioned processing, the yield rate after the dyeing is 98%.
Embodiment 2: 1 ton of cotton interlock fabric, specification 32S/1 color: LightPink
Open-width: the interlock fabric open-width is become door width of cloth 180cm.
Biology enzyme impregnation process process: advance the cloth water inlet, bath raio: 1: 5.5, cellulase 8KG, alkaline pectase 4KG, and add 35% hydrogen peroxide 24KG, 95 ℃ of temperature, time 30min.Discharge water, water inlet neutralization again adds glacial acetic acid 5KG, 50 ℃ of temperature, and time 10min discharges water then, and water inlet adds deoxidation enzyme 1KG, 50 ℃ of temperature, time 10min, dyeing.
Through the fabric of above-mentioned processing, the yield rate after the dyeing is 98%.
Embodiment 3: 1 ton of cotton plain, specification 32S/1.Color: bleaching
Open-width: the plain open-width is become door width of cloth 180cm.
Biology enzyme impregnation process process: advance the cloth water inlet, bath raio: 1: 6.5, cellulase 6KG, alkaline pectase 3KG, protease 3 KG, and add 35% hydrogen peroxide 24KG, brightening agent 3KG, 95 ℃ of temperature, time 50min.Discharge water, the water inlet neutralization adds glacial acetic acid 5KG again, 50 ℃ of temperature, and time 10min discharges water then, soft 40 ℃ of water inlet, time 20min, dyeing.
Through the fabric of above-mentioned processing, the yield rate after the dyeing is 98.5%.
