The invention aims to overcome the deficiencies of the prior art and provide the penetrant which is used for the s hort-process pretreatment of pure-cotton woven fabric and has good permeability, alkali resistance and strong decontamination and washing capability.
Description
Technical field
The present invention relates to a kind of alkali-resistant penetrant that is used for the short process pretreatment of pure-cotton woven fabric.
Background technology
Cotton fiber is a kind of natural fabric, contains impurity such as pigment, pectin, cotton seed hull, usually can give the cotton yarn starching in the weaving process again, must be by operations such as destarch, kiering, bleachings that Impurity removal is clean before dyeing.Short process pretreatment operating rate is than very fast, require working solution in 10～15 seconds time, to infiltrate through fiber, but the cotton grey cloth that is untreated is not hydrophilic, particularly thick and heavy woven cotton fabric, working solution is difficult to infiltrate through fibrous inside, therefore require alkali-resistant penetrant that good penetration, stability are arranged under strong alkaline condition, the decontamination scourability also requires very high.
Alkaline-resisting kiering bleeding agent will possess following several indexs:
A, good penetration power.The short process pretreatment equipment of printing and dyeing mill generally has two to pad groove, its technological requirement all is that room temperature is padded, and the speed of a motor vehicle is all at 40～50 meters/minute, and printing and dyeing mill's gassing frame that also has and cold rolling heap clot connect together, the speed of a motor vehicle just reaches more than 80 meters/minute, have in addition above 100 meters/minute.To pad the time of working solution in padding groove be very short to cloth in other words, the time of padding that has is about 20 seconds, the equipment that has pads time less than 10 seconds still, make working solution be adsorbed on fiber surface and rapid permeability fibrous inside in a short period of time to the fabric that has slurry, and require infiltration evenly, this just requires alkaline-resisting kiering bleeding agent under the highly basic condition good penetration must be arranged, and could satisfy the requirement to printing and dyeing mill's technology.
B, good alkali resistance to be arranged.Concentration 40～60g/L NaOH of alkali in the alkali oxygen working solution of printing and dyeing mill, what have also can be higher, replenish the concentration ratio groove of liquid and want high by 20～30%, that calculates like this that the NaOH concentration replenish liquid has will be up to more than the 100g/L, this just requires the alkali resistance of alkaline-resisting kiering bleeding agent could satisfy the alkaline-resisting requirement of printing and dyeing mill to the kiering bleeding agent more than 120g/L NaOH.
C, good kiering effect and impurity elimination effect are arranged.A large amount of fiber commensal and impurity are arranged on the cotton fiber, mainly contain cotton wax, pectic substance, nitrogen substance, cotton seed hulls, natural impurity and natural colouring matter etc., also have the slurry on the yarn in the weaving process in addition.Therefore require auxiliary agent that good swelling action, dispersion and emulsion effect, decontamination etc. must be arranged, good anti-precipitation more especially will be arranged, could wash impurity on the fabric and slurry come like this, prevent the contamination again of slurry simultaneously.
D, short process pretreatment auxiliary agent must be the environment-friendly type auxiliary agents, and the health of harm humans is not free from environmental pollution, the ecological resources around not destroying.
Along with the development of producing, during efficient, energy-conservation, joint, shorten technology, stabilised quality becomes the common objective that printing and dyeing mill is pursued.Traditional technological process destarch, kiering, the bleaching three-step approach of cotton pre-treatment, this three-step approach exists that process route is long, efficient is low, equipment takes up an area of big, the big problem of energy consumption, along with rising steadily of energy prices, cotton pre-treatment process develops into to move back and boils one-step method or fevering cooking floating one-process, produces needs in order to satisfy, and also needs to add bleeding agent when adding scouring agent usually in working solution.The pre-treatment abbreviated system because the speed of a motor vehicle than very fast, the processing time short, to the requirement of chemical alkali-resistant bleeding agent than higher.
Summary of the invention
The objective of the invention is in order to overcome weak point of the prior art, a kind of short process pretreatment of pure-cotton woven fabric that is used for is provided, have good penetration, alkali resistance, the bleeding agent that decontamination and washability are strong.
In order to achieve the above object, the present invention adopts following scheme:
