Summary of the invention
The object of this invention is to provide a kind of low cost, high yield, the nylon of low defect rate, cotton mixture fabric dye black single bath process technique.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of nylon, cotton mixture fabric dye black single bath process technique, comprise the steps: grey cloth → cold dome → destarch → predetermined → mercerising → unhairing → pre-treatment (rinsing) → dyeing → dehydration → open-width → open width washing → finished product sizing → inspection, clot, packaging;
Wherein, staining procedure comprises: at normal temperatures, in the dye vat being equipped with nylon, cotton mixture fabric and water, add acid levelling agent; Be uniformly distributed in after in dye vat until acid levelling agent, then add soda ash adjust pH to 9.5-10.5; Then activity/acid single bath process dyestuff is added; Add glauber salt again; Then heat to 75-82 DEG C with liter per minute 1 DEG C, insulation 25-32 minute; Heat to 95-100 DEG C with liter per minute 1 DEG C again, insulation 25-32 minute; Then fall 2 DEG C be cooled to 68-73 DEG C with per minute; Then open cylinder, sample, check colors; Draining again; Then intake, and be warming up to 78-82 DEG C, insulation 8-12 minute; Then draining, cylinder is washed out.
As the further setting of such scheme, the concentration of described acid levelling agent be 1 grams per liter (calculate based on dye vat water level, as: water level reach 3 tonnages put time, the amount adding acid levelling agent is 3 kilograms).
The concentration of described glauber salt be 80 grams per liters (calculate based on dye vat water level, as: water level reach 3 tonnages put time, the amount adding glauber salt is 240 kilograms).
Described acid levelling agent is added to after in dye vat, and dye vat will carry out running 5 minutes, then adds soda ash adjust pH.
In described predetermined process, temperature is 180-200 DEG C, and to enter cloth speed be 58-62m/min.
In described mercerising step, adopt concentration to be the liquid caustic soda of 200-220 grams per liter, and to enter cloth speed be 70m/min.
In described pre-treatment step, by the water under normal temperature, heat to 90-98 DEG C with liter per minute 1.5 DEG C, insulation 20-30 minute.
In described finished product fixating shape step, temperature is 190-195 DEG C, and to enter cloth speed be 28-32m/min.
Nylon of the present invention, cotton mixture fabric dye black single bath process technique, energy resource consumption little (especially the consumption of water compare two-bath process greatly reduce), production cost is low, output is high (two-bath process needs 7-8 hour just can go out finished product, and the present invention only needs 3-4 hour just can go out finished product), defect rate is low.
