(2) grey cloth pre-setting: adopt needle plate type forming machine, controls temperature and is 170-190 DEG C, and the pre-setting time is 40-60s, and fabric width requires bigger 5%-8% than finished product; Grey cloth situation after pre-setting: door width 210cm, grammes per square metre 253g/m, shrinkage factor 3%;
(3) reduction cleaning: be cooled at 60 DEG C and add reduction detergent and glacial acetic acid, wash once after insulation 20-30min, place into immersion 10-15min in 80-90 DEG C of hot water;
(4) dyeing assistant formula design, preparation and consumption: include the raw material composition of following weight portion:
Polymethacrylate emulsion 17-25 part;
NPE 13-15 part;
Amino silicone alkanes coupling agent 7-10 part;
Nano aluminium oxide 10-15 part;
Waterglass 1-5 part;
Barium sulfate 15-20 part;
Glacial acetic acid 2-3 part;
Carboxymethyl cellulose sodium 0.3-1 part;
Paregal O 8-10 part;
Water is about 70-100 part;
The compound method of dyeing assistant: add the normal-temperature water of 30% in material bucket, add polymethacrylate emulsion, NPE, Carboxymethyl cellulose sodium and phosphite ester kind antioxidant, after stirring and dissolving 40-55 minute, add water and all the other components of surplus, continue stirring to uniformly;
The consumption of dyeing assistant: during dyeing add dyeing assistant 10-20g/L, and with regulates dye time dye liquor pH value; (5) dyeing: pad dye liquor (pick-up rate is 60%-70%) → wet (steam temperature 120-130 DEG C, humidity 35-45%, time 2-4min) → cold water that steams and wash → Warm Wash (40 DEG C-50 DEG C) → soda boiling → wash → dry; Wherein, formula for dye liquor is: reactive dye 20-40g/L, the dyeing assistant 10-20g/L described in step (3), migration inhibitor 8-12g/L, sodium bicarbonate 10-15g/L, anhydrous sodium sulfate 3-5g/L, paregal O 6-10g/L, bath raio 1:10-15; After described soda boiling refers to that Warm Wash terminates, first time adds soda and controls the pH value of water-bath, it is warming up to 80-85 DEG C again and is incubated 25-35min, again clean, again clean second time after terminating and add soda and control ph, and then be warming up to 80-85 DEG C and be again incubated 25-35min, and then clean, it is eventually adding glacial acetic acid and is warming up to 40-45 DEG C and then insulation 5-15min;
(6) fixation Final finishing: adopt steamer that fabric after dyeing is arranged, to increase the colour fixation of dyestuff on fabric, after fabric sends into steamer, fabric fiber when high temperature is damp and hot can occur swelling, temperature in steamer steaming box is 100-102 DEG C, pass through high temperature steam treatment, steam pressure is 0.3-0.4MPa, the temperature of high-temperature steam is 160-170 DEG C, water vapour penetration mode is first permeated from inside to outside, ecto-entad infiltration again, fabric cannot be swelling at diametric(al) fiber, can only be swelling towards warp-wise, again fabric is taken out cold front heavy rain after warp-wise is swelling, make the stabilization of fiber, the time arranged in steamer is 2-3 minute, the swelling dyefastness making fabric of warp-wise and dyeing uniformity are greatly improved.
2. the colouring method of cation-modified cellulose base fiber fabric according to claim 1, it is characterised in that: the solid content of described polymethacrylate emulsion is 40-50%.
3. the colouring method of cation-modified cellulose base fiber fabric according to claim 1 and 2, it is characterised in that: the particle diameter of described nano aluminium oxide is below 50nm.
