Description
Technical field
The invention belongs to fabrics printing and dyeing technical field, in particular to a kind of normal pressure of biology base PTT series polyester textile
Exhaust process.
Background technique
PTT fiber (ptt fiber) is by dimethyl terephthalate (DMT) (DTA) or terephthaldehyde
The polymer that sour (PTA) and 1,3-PD (PDO) polycondensation are formed, then a kind of synthetic fibers processed through spinning.PTT resilience
It is high, with splendid wearability and pollution resistance, dyeability is excellent.Compared with traditional petroleum base ptt fiber, biology base PTT
Fiber using the resulting PDO of microbial fermentation technology as the aggregated spinning of raw material due to being formed, the renewable, environment with raw material
The advantages that pollution is few, more meets the theory of " Green Development ".In general, the traditional colouring method of polyester textile mainly has high temperature
High-pressure dyeing, carrier dyeing process and pad-dry-cure dyeing method.In place of the equal Shortcomings of these three colouring methods: in carrier dyeing process
Common carrier has certain toxicity, and high-temperature and high pressure dyeing process and the energy consumption of pad-dry-cure dyeing method are big, and to dyeing installation require compared with
It is high.Further, since biology base PTT series polyester textile is very sensitive to temperature, high dyeing temperature easily makes fabric hand feel be hardened.
It is special that above-mentioned traditional polyester dyeing method --- high temperature and high pressure method and pad-dry-cure dyeing method can directly result in the memory of biology base PTT fabric
The forfeiture of property.Therefore, it is badly in need of developing a kind of colouring method of dyeing at normal pressure suitable for biology base PTT fabric.
Vegetable colour is since the characteristic of natural environmental-protective is now chiefly used in textile dyeing, according to the literature, currently used for petroleum base
The natural dye of ptt fiber dyeing is only limitted to natural plant pigment rheum emodin and Chrysophanol.Natural plant pigment rheum emodin and big
Yellow phenol has been all made of high temperature and high pressure method to the dyeing of ptt fiber, and equipment choosing is infrared proof press (Wang Jiawei natural dye
To research [D] .City: University Of Suzhou of dyeing polyester fibers performance, 2009.).Although using vegetable colour, it is contaminated
Color method is more demanding to dyeing installation.
Madder (latin name Rubia cordifolia) dyestuff is a kind of natural vegetable colour.Its main component is anthracene
Naphthoquinone derivatives rubican, purpurin, purpuroxanthin, 1- hydroxy-2-methyl anthraquinone etc..Anthraquinone dyes are to cellulose fiber
The affinity of peacekeeping azelon is higher, but lower for the affinity of dacron fabric, and dye-uptake is low, and dyefastness
It is poor.In addition, vegetable colour is a kind of mixture system, ingredient multiplicity is upper in dyeing course to contaminate complicated mechanism, easily occurs
The problems such as dyeing defect, uneven dyeing.
The two is combined and develops a kind of dyeing at normal pressure technique by the natural characteristic based on biology base PTT and gamene vegetable dye,
The environmentally protective intension of its process will be fully demonstrated, but the dyeing that madder is used for biology base PTT fabric is had
Certain challenge.Have no that pertinent literature is reported at present.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of normal pressure dippers of biology base PTT series polyester textile
Skill overcomes the defect of existing traditional polyester dyeing method (high temperature and high pressure method, support methods, pad-dry-cure dyeing method), and having filled up will
Blank of the madder for the dyeing at normal pressure of biology base PTT fabric.
A kind of atmospheric low-temperature exhaust process of biology base PTT series polyester textile of the invention, comprising:
(1) one bath of desizing washing processing is successively carried out to biology base PTT series polyester textile, pre-setting, alkali process obtains
Pretreated fabric；
(2) madder of 1-5%o.w.f is added in dye bath, adjusting Value in Dyeing Process is 3-6, and ultrasonic treatment obtains madder
Careless dye liquor；
(3) the pretreated fabric that step (1) obtains is placed in the madder dye liquor that step (2) obtains at room temperature, is begun
50-60 DEG C of temperature of dye, 1-2 DEG C of heating rate/min, holding temperature are 90-95 DEG C, soaking time 30-60min, and dye, which finishes, to be taken
Out, elute, soap, wash, dry to get.
The process conditions of the bath of desizing washing one processing in the step (1) are as follows: using compounding detergent and lye to fabric
Desizing washing is carried out, is then dried.Purpose is the greasy dirt spot on slurry and fabric when removing face weave.
The compounding detergent is that lauryl sodium sulfate and polyoxyethylene ether are compounded by grade ratio, and total dosage is 5g/L.
The lye is sodium hydroxide solution, dosage 3g/L.
The temperature of the drying is 40-50 DEG C.
The technological parameter of pre-setting in the step (1) are as follows: xeothermic sizing, temperature are 130-140 DEG C, time 30-
60s, pre-tension 0-1%.Pre-setting before dyeing can eliminate the planarization of existing fine wrinkle and holding fabric on fabric.
The technological parameter of alkali process in the step (1) are as follows: dip dyeing, bath raio 1:40-1:50, concentration of lye 10-
30g/L, treatment temperature are 80-95 DEG C, handle time 30-90min.Biology base PTT series fabric is temperature sensitive, higher temperature
Degree can make fabric hand feel harden, and elasticity reduces.And elasticity is a kind of unique property that ptt fiber fabric has.After thermal finalization
Fabric feeling is hardened, and the flexibility and drapability of fabric can be improved by alkali process.
CH is used in the step (2)3COOH-CH3COONa buffer adjusts dye bath pH.
The time being ultrasonically treated in the step (2) is 20-40min.
The technological parameter soaped in the step (3) are as follows: bath raio 1:20-1:60, NaOH 2g/L, sodium hydrosulfite 2g/L soap
50-60 DEG C of temperature, soap time 20-40min.
Beneficial effect
(1) biology base PTT series polyester textile is dyed using colouring method provided by the invention, normal pressure can be used
Dyeing installation, it is easy to operate, it consumes energy low；Other auxiliary agents can not be added in dye liquor, reduce the discharge of chemical substance.Using
Biological poly ester fiber is contaminated on natural plant dye, dyeing course environmental protection meets the theory of green production.
(2) the present invention is based on the natural characteristics of biology base PTT and gamene vegetable dye, and the two is combined and develops a kind of normal pressure
Dyeing will fully demonstrate the environmentally protective intension of its process.
