Description
Technical field:
The invention belongs to textile processing technical field, relate to a kind of knitted fabric and at overflow dyeing beBulk cargo carries out the new technology of overflow dyeing with minimum start water level in putting, particularly a kind of knittingThe low bath ratio dyeing method alive of thing.
Background technology:
At present, in field of industrial production, the dyeing of textile is high energy consumption, high water consumptionWith one of industry of high pollution, according to statistics, the coal consumption of the every myriametre cloth of China is on 3 tons of left sidesThe right side, power consumption in the time of 450KW/, water consumption 300-400 ton, the 3-5 that energy consumption is international most advanced levelDoubly, water consumption is 2-3 times, and dyeing water accounts for whole textile industry water consumptions 80%, itsThe water causing pollutes particularly serious; Therefore, development have environmental protection, energy-conservation and consumption reduction dyeing and finishing workSkill is the developing direction of textile auxiliary's industry in recent years, is also that national policy is encouraged simultaneouslyKey areas. Knitted fabric normal dyeing technique in the prior art, to contaminate as main, adopts moreReactive dye overflow machine dyeing, and this reactive dye Overflow dyeing is realized industrializationNeed be with a large amount of salt (glauber salt and salt) when dyeing, its fixation also needs with a large amount of soda ash,As dye the dark kind such as black, navy, and glauber salt is used 90%-100%, and soda ash is used20%-25%, salt, alkaline consumption consumption are huge, if annual 20% amount is dark kind, within 1 year, press2000000 tons of output are calculated, and salt consumes 2,000,000 tons, and soda ash consumes 5,000,000 tons, if add other80% light coloured variety, always consumes salt, alkali number is surprising, and consumes large water gaging while finishing and rinse dying,Ton water consumption is than being 1:10-12, and the dye-uptake of reactive dye only has 70%-90%, and sewage quantity is large,Colourity is high, has strengthened difficulty and the expense of sewage disposal. So, in order to improve dyeing efficiency,The dyeing reducing costs and seek a kind of low bath raio alive has market prospects very much.
Summary of the invention:
The object of the invention is to overcome the shortcoming that prior art exists, solve knitted fabric in dyeingIn environmental protection and energy-saving and cost-reducing problem, seek to design the low bath ratio dyeing method alive of a kind of knitted fabric,For the knitted fabric overflow dyeing of field of textiles.
To achieve these goals, technical solutions according to the invention are in improved low bath raio aliveIn coloring system device, complete, comprise following processing step:
(1) knitted fabric pre-treatment: first knitted fabric is immersed to the pre-treatment that fills minimum dyeing water levelIn the staining jar of liquid, temperature control 60-80 DEG C is carried out oxygen and floats pre-treatment 20-30min; Wherein minimum dyingLook water level is that pre-treatment immersion is crossed knitted fabric 3-10cm;
(2) dyeing: again the knitted fabric after pre-treatment is immersed again and fill minimum dyeing water level and dyeIn the staining jar of liquid, 30-60min dyes at the temperature of 60-80 DEG C; The PH of described dye liquorValue is 11-12, and minimum dyeing water level is that dye liquor soaked knitted fabric 3-10cm;
(3) knitted fabric post processing: the temperature in staining jar is down to by the reduction of speed of 1 DEG C/min50 DEG C-60 DEG C, emit dye liquor, then add concentration to be by the weight ratio of 1:1 in staining jarThe aqueous acetic acid that 1g/ rises and every liter of soaping agent aqueous solution containing 1g soaping agent, make after dyeingKnitted fabric immerses containing in the soaping agent aqueous solution of acetic acid, to the knitted fabric 20-30min that soaps, realThe post processing of existing knitted fabric;
(4) arrange: after knitted fabric being completed to conventional post processing in staining jar, knitted fabric is dragged forGo out staining jar, through conventional dehydration, wet expanding, oven dry and sizing finishing technique, complete pinThe low bath ratio dyeing alive of fabric.
Pretreatment liquid of the present invention be every liter comprise respectively 0.5-1.0g deoil yarn agent andThe mixed aqueous solution of enzyme is bathed in 1.0-2.0g kiering one; The yarn agent of deoiling is fatty acid ester and aromatic alcoholMixture; It is one or more in destarch enzyme, cellulase and pectase that enzyme is bathed in kiering oneMixture; Described dye liquor is every liter and comprises respectively 30-50g reactive dye, 30-40gNa2SO4Mixed aqueous solution with 10-20g food grade soda ash; Described soaping agent is conventional anti-stainingSN polyacrylic macromolecular compound soaping agent; Described knitted fabric is all kinds of pure cotton pinsFabric.
The present invention compared with prior art, improved conventional needle fabric overflow dyeing water consumption large,The fraud that dye addictive use amount is large, dyeing time is long, energy resource consumption is large, wastewater discharge is largeEnd; The discharge of dyeing waste-water reduces more than 30%, has solved conventional needle fabric dyeing process high dirtyThe problem such as dye; Its integrated artistic is simple, and design principle science is used handling safety reliable, jointEnergy emission reduction effect is good, dyeing environmental friendliness.
