Description
Technical field
The present invention relates to a kind of method for sorting of wool fabric, especially relate to one shitosan/TiO
2the method of composite finishing wool fabric.
Background technology
Along with light-weight wool fabric widely using in summer, problem that person pays close attention to that the deodorization of wool fabric, antibacterial, uvioresistant and sun-resistant performance etc. have become spinstry.Wool fabric is through long-time Ultraviolet radiation, the dye molecule absorb photons on fabric can be made to become excitation state, thus cause dyestuff generation photochemical reaction, reduce the light fastness of fabric, uvioresistant and the sun-resistant performance of therefore taking wool fabric summer just become the key factor affecting product quality and class.
Nano-TiO
2with the chemical stability of its brilliance, high efficiency, the advantage such as selective, not soluble and safe, inexpensive, pollution-free, be acknowledged as one of focus of tech Textiles application study.Nano-TiO
2in the mixed emulsion finishing agent that powder is made, because nano particle has very strong adsorptivity, finishing agent can be made to be adsorbed on wool surfaces securely, be conducive to finishing agent and be coated on fiber epicuticula fully comprehensively, thus weakening direction friction effect, reduce the frictional resistance of fiber surface, imparting wool fabric is lasting, long-acting shrinkproof performance, reach the finishing effect of felt proofing, keep the style that wool fabric is good, color and luster, gas permeability and feel, meet machine washing, the requirement of anti-fuzz balls, simultaneously, this method for sorting technological process is short, harmless to human body during process, the waste water environmentally safe produced, and arrange after fabric feeling better.
Summary of the invention
The object of this invention is to provide a kind of shitosan/TiO
2the method of composite finishing wool fabric.
The present invention is to solve the defect such as the finishing effect existed in existing wool fabric method for sorting is not good, arranging process is numerous and diverse, dressing liquid is big for environment pollution.
Technical scheme of the present invention is: a kind of shitosan/TiO
2the method of composite finishing wool fabric, described method at least comprises the steps: the preliminary treatment of a. fabric: cleaned by wool fabric and be placed in warm water, is the ultrasonic wave process 30 ~ 60 minutes of 30 ~ 40KHz by frequency; B. composite finishing liquid preparation: get a certain amount of butyl titanate and be dissolved in the ethanol of certain volume, add a certain amount of diethanol amine, the mixed liquor of the second alcohol and water of certain volume is added after stirring, continue to stir a period of time, then raised temperature, forms nano-TiO after stirring a period of time under reflux state
2colloidal sol; To nano-TiO
2in colloidal sol, add a certain amount of shitosan, crosslinking agent citric acid and catalyst inferior sodium phosphate, stir, obtain composite finishing liquid; C. wool fabric arranges: pretreated wool fabric is placed in composite finishing liquid, and described arrangement is that two leachings two are rolled, and pick-up rate is 85%, and padding temperature is 50 ~ 65 DEG C; D. preliminary drying: the wool fabric after arranging is dried 3 ~ 5 minutes at 70 ~ 80 DEG C; E. cure: pre-baked wool fabric is baked 2 ~ 5 minutes at 140 ~ 170 DEG C; F: washing: with the hot wash fabric of 60 DEG C; G: dry: wool fabric is dried at 70 ~ 80 DEG C.
The nano-TiO of described preparation
2the concentration of colloidal sol is 0.3 ~ 0.5mol/L; The consumption of described shitosan is 0.5 ~ 1.2% owf; The consumption of described citric acid is 2 ~ 4% owf; The consumption of described inferior sodium phosphate is 1 ~ 3% owf.
Described nano-TiO
2in the preparation process of colloidal sol, the mol ratio of butyl titanate, diethanol amine, second alcohol and water is 1:0.7 ~ 0.9:20:0.5 ~ 0.6.
The beneficial effect that the present invention produces is: compared with prior art, composite finishing method provided by the invention, adopts shitosan and nano-TiO
2the mixture of colloidal sol as composite finishing agent, nano-TiO
2colloidal sol is not only conducive to the graft reaction efficiency improving shitosan, and nano-TiO
2after colloidal sol itself is adsorbed on wool surface, fine and close gel film can be formed through curing; Wool fabric after arrangement has extraordinary antibacterial, shrinkproof, the function such as uvioresistant, Sun-proof.Method for sorting is harmless to human body, the waste water environmentally safe of generation, and the fabric feeling after arrangement is better.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described.
A kind of shitosan/TiO
2the method of composite finishing wool fabric, described method at least comprises the steps: the preliminary treatment of a. fabric: cleaned by wool fabric and be placed in warm water, is the ultrasonic wave process 30 minutes of 30 ~ 40KHz by frequency; B. composite finishing liquid preparation: get a certain amount of butyl titanate and be dissolved in the ethanol of certain volume, add a certain amount of diethanol amine, the mixed liquor of the second alcohol and water of certain volume is added after stirring, continue to stir a period of time, then raised temperature, forms the nano-TiO that concentration is 0.4mol/L under reflux state after stirring a period of time
2colloidal sol, the mol ratio of described butyl titanate, diethanol amine, second alcohol and water is 1:0.8:20:0.6; To nano-TiO
2in colloidal sol, add 1.0% owf shitosan, 3.5% owf crosslinking agent citric acid and 1.5% owf catalyst inferior sodium phosphate, stir, obtain composite finishing liquid; C. wool fabric arranges: pretreated wool fabric is placed in composite finishing liquid, and described arrangement is that two leachings two are rolled, and pick-up rate is 85%, and padding temperature is 50 ~ 65 DEG C; D. preliminary drying: the wool fabric after arranging is dried 3 minutes at 80 DEG C; E. cure: pre-baked wool fabric is baked 3 minutes at 155 DEG C; F: washing: with the hot wash fabric of 60 DEG C; G: dry: wool fabric is dried at 80 DEG C.
