Skill belongs to the dyeing and finishing field of fabric.
Background technology
Polyester cotton is made of two kinds of fibers of different nature, and dyeing and finishing processing needs to take into account two kinds of fibres of different nature
Dimension, traditional work flow is first by cotton pre-treating technology pre-treatment, then contaminates and wash reduction and wash, and then contaminates cotton and soaps, entire technique
Process need to take 12 it is small when more than, energy consumption and water consume are big, and production cost is higher, while give off largely useless containing high pollution object
Water.
The content of the invention
The object of the present invention is to provide a kind of polyester cotton short route dyeing and finishing technologies, using One-step pretreatment, wash
Cotton one-bath process abbreviated system shortens the dyeing and finishing flow of polyester cotton, when achieving the effect that section, energy saving, emission reduction.
To achieve the above object, the technical solution adopted by the present invention is：

Polyester-cotton blend one-bath process：
S2a presses bath raio 1:10, polyester-mixed cotton cloth, the clear water after pre-treatment are placed in machine cylinder；
S2b adds in disperse dyes 1-6%owf, neutral fixation reactive dye 1-8%owf, sodium chloride 20-40g/L, level dyeing
Agent 1-3g/L；
S2c is warming up to 80 DEG C with the speed of 2 DEG C/min, keeps the temperature 20min, then is warming up to 120 DEG C with the speed of 1 DEG C/min,
Keep the temperature 30min；
S2d is cooled to 60 DEG C, and removal waste fluid, clear water are washed；
It soaps：
Soaping agent 2g/L, bath raio 1:10th, 90 DEG C of temperature, time 10min；
Final finishing：
S3a amino silicon oil emulsions in mass ratio:Silver antibacterial agent:Water=30:24:500 proportional arrangement dressing liquid, is fully stirred
Mix dissolving；
S3b in above-mentioned dressing liquid, impregnates polyester cotton thorough impregnation 5 minutes, two leachings two are rolled, and pick-up rate is more than
85%, 180 DEG C of drying；
The silver antibacterial agent, its preparation method are：
1) 15g nano-titanium dioxides are weighed, measure 8mL silane resin acceptor kh-550s, are mixed with 160mL absolute ethyl alcohols, 60
DEG C 5h is stirred at reflux, is cooled to room temperature, mixed liquor is centrifuged, washed with methanol, is dried for standby at 70 DEG C；
2) the nano-titanium dioxide 8g of coupling agent surface modification is weighed, is dissolved in 80mL tetrahydrofurans, adds in bis- sulphur of 10mL
Change carbon and 1mL triethylamines, be stirred to react 4h at room temperature, obtain aminodithioformic acid nano-titanium dioxide；
3) aminodithioformic acid nano-titanium dioxide 6g is taken to be scattered in 100mL water, adds in excess 0.01mol/L's
Silver nitrate solution is protected from light complex reaction 0.5h, removes extra silver nitrate, obtains silver antibacterial agent.
Scouring agent, hydrogen peroxide stabilizer described in One-step pretreatment are product commonly used in the art.
Scouring agent is multi-functional scouring agent HA-SSA (federal Fine Chemical Co., Ltd in Guangdong), alkaliproof highly effective scouring agent
One kind in XY-1 (Jiangsu Hai'an Petrochemical Plant).
Hydrogen peroxide stabilizer is efficient hydrogen peroxide stabilizer Hansi KEW-560 (the limited public affairs of Jiangsu Chinese Northey chemicals
Department), one kind in hydrogen peroxide bleaching stabilizer CN-215 (Guangzhou Cheng Na Chemical Co., Ltd.s).
The chelated dispersants, its preparation method are：
A, by molar ratio 1:1.1 polyethylene glycol, epoxychloropropane are added in four-hole boiling flask, and addition accounts for polyethylene glycol, ring
The catalyst of oxygen chloropropane total mass ratio 2% with heating water bath to 85 DEG C, reacts 4h；Cooling with n-hexane washed product, is steamed
Except unreacted epoxychloropropane；
B, iso-heptanol (2- methyl -2- hexanols) is added in into the product that a steps purify, 90 DEG C is warming up to and be condensed instead
Should, after reacting one section of 4h, 50 DEG C are cooled to, 3- chlorine-2-hydroxyl propyl sodium phosphates is added in, is warming up to 75 DEG C, is condensed again
5h is reacted, after complete reaction, cooling, with acetone extract crude product, decompression, which filters, removes acetone to get chelated dispersants.It is poly-
Ethylene glycol, iso-heptanol, the molar ratio of 3- chlorine-2-hydroxyl propyl sodium phosphates are 1:1.2:1.3.
Containing oxyethylene group, hydroxyl and phosphate radical in chelated dispersants molecule, oxyethylene group has good scattered, emulsibility
Can, it, can be by stable emulsions such as slurry, the impurity in water, scattered in pre-treating technology, hydroxyl, phosphate radical can effectively be complexed, chela
Metal ion prevents metal ion catalysis hydrogen peroxide too quick decomposition.
The molecular weight of the polyethylene glycol is 400,600, i.e. polyethylene glycol 400, Macrogol 600.
The catalyst is boron trifluoride-ether complex.
The preparation method of the 3- chlorine-2-hydroxyl propyl sodium phosphates is：1mol hydrogen phosphate dihydrates are added in into reaction kettle
Sodium and 300mL water, are warming up to 45 DEG C, and the epoxychloropropane of 1.2mol is slowly added dropwise, and 80 DEG C are warming up to after dripping, and react to liquid
Face filters product without oil reservoir, decompression, removes water, epoxychloropropane etc., is then extracted with ethyl alcohol, and decompression is filtered up to the chloro- 2- of 3-
Hydroxypropyl sodium phosphate.
Polyester-cotton blend one-bath process is to employ neutral fixation reactive dye and disperse dyes to polyester-cotton fabric one-bath dyeing.
The disperse dyes are to disperse gorgeous Huang, disperse golden yellow, disperse yellow brown, disperse orange, and dispersed ruby disperses orchid, point
Deep blue, disperse navy blue is dissipated, disperses black, disperse yellow, disperse red, purse red disperse dye, disperse violet, the one or more during scattered kingfisher is blue.
The neutral fixation reactive dye are active red CN-3B, active yellow CN-EX, reactive blue CN-MG, active palm fibre CN-
One or more in AL.
Neutral fixation reactive dye are usually the dyestuff of dichloro s-triazine class formation, the difference with regular activated dyestuff maximum
It is exactly not have to add alkali in dyeing course, in neutrality, 100~130 DEG C, active group can be sent out with the hydroxyl of cotton fiber
Raw reaction and it is fixed.The compatibility of dyestuff is higher, due to there is no the presence of alkaline agent in dye liquor, the hydrolysis of dyestuff in dyeing course
Seldom, therefore the dye uptake of dyestuff, fixation rate are higher, and fully the shifting of dye molecule is convenient in swelling to one side cotton fiber in high temperature
It is dynamic, during another aspect high temperature the movement of dye molecule also greatly speed up so that in dyeing course dye molecule shifting dye
Greatly improve.
The amino silicon oil emulsion is commercially available conventional products.
When preparing silver antibacterial agent, first with Silane coupling agent KH550 surface-modified nano titanium dioxide, then with carbon disulfide with
Amino reaction in KH550, triethylamine is acid binding agent, generates dithiocar-bamate, then makes dithiocar-bamate
It is complexed with silver, forms silver complex type antibacterial.
Polyester cotton short route dyeing and finishing technology of the present invention shortens desizing, concise, bleaching traditional pre-treating technology into
One step single bath process, and dyed with neutral fixation reactive dye and disperse dye one-bath, fabric is carried out with silicone oil, silver antibacterial agent
Finishing functions make polyester-cotton fabric have soft, anti-microbial property.
