Description

A kind of automatic temperature-control air-permeable outdoor sport suit fabric and preparation method thereof
Technical field
The present invention relates to sweat shirt field, be specifically related to a kind of automatic temperature-control air-permeable outdoor sport suit fabric and preparation method thereof.
Background technology
Clothing, food, shelter, the capable primary demand as people's lives, along with the progress of science and technology, the living standard of the people is progressively improving, and the demand of the people is also improving constantly.Current, outdoor sports have become people's important sports events after work.Due in the process of motion, people knows from experience generation heat and sweat, and common sportswear is airtight, not absorbing sweat, in such motion process, people can feel very uncomfortable, reduce the enjoyment of motion, therefore need to work out a highly-breathable, intelligent thermoregulating motion textiles for people provide a kind of cold time heat release, heat absorption during heat, eliminate variations in temperature in motion process and the warm-cold sensitivity that produces, improve the enjoyment of people's motion.
Now, sports is flourish, and temperature-regulation fabric has become the study hotspot of domestic and international textile function product.At home, the investigation and application of temperature-regulating fiber is also in the starting stage, and market does not also have full ripe product.But because temperature-regulating fiber has heat-storage thermoregulation function, and have excellent can with the blending of other various fibers, its range of application and wide, therefore, will have wide market development space.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of automatic temperature-control air-permeable outdoor sport suit fabric and preparation method thereof is provided.
The present invention in order to the taked technical scheme that solves the problem is: a kind of automatic temperature-control air-permeable outdoor sport suit fabric, becomes precast body by warp thread with weft yarns, after precast body is flooded, and obtained fabric; Wherein, warp thread is made up of the raw material of following composition by weight: modified nylon fiber 20-30 part, modified viscose fiber 45-50 part and modified acrylic fibre 20-35 part; Weft yarn is made up of the raw material of following composition by weight: modified polyester fibre 50-60 part and milk fibre 40-50 part.
In the present invention, described modified nylon fiber is polyethylene glycol graft-polyamide 6, and wherein, molecular weight polyethylene glycol is 4000-6000.
In the present invention, described modified viscose fiber is made up of the raw material of following composition by weight: rayon spinning liquid 90-95 part, microcapsule compounded phase-change material 5-10 part.
Modified polyester fibre in the present invention is polyethylene glycol grafting polyethylene terephthalate, and wherein, molecular weight polyethylene glycol is 1000-2000.
A preparation method for automatic temperature-control air-permeable outdoor sport suit fabric, comprises the following steps:
Step one, be the n-tetradecane of 2:4:1 by weight ratio, hexadecane, n-eicosane be configured to mixed solution, mixed solution is placed in there-necked flask heating water bath, bath temperature is 70-80 DEG C, after stirring 10-15min with the rotating speed of 1000-1300rpm, according to mixed solution: emulsifying agent: the weight ratio of the PVA aqueous solution=10:0.2:0.5-1.0, add emulsifying agent and the PVA aqueous solution, 1-1.5h is stirred with the rotating speed of 450-600rpm, form emulsion, then the dilute sulfuric acid that concentration is 10% is added, regulate emulsion pH to 4-5, for subsequent use;
Step 2, be that the melamine of 1:4.5-5 and formaldehyde are placed in container and form solution by mol ratio, in 75-80 DEG C of airtight stirring 0.5h, then add the Na that concentration is 10-15% 2cO 3weak solution, the pH to 9-10 of regulator solution, 45-50 DEG C is stirred to solution clear; Then according to this solution: the volume ratio of emulsion=3:5, this solution is added in emulsion prepared by step one, stir 2.5-3h, form suspension, be separated by suspension with centrifuge, centrifugal speed is 2500-3000rpm, by the centrifugal precipitation obtained, spent glycol and deionized water wash 3-5 time respectively, then be placed in 40-50 DEG C of baking oven and dry 10-12h, obtained microcapsule compounded phase-change material, for subsequent use;
Step 3, parts by weight according to rayon spinning liquid 90-95 part, microcapsule compounded phase-change material 5-10 part, take rayon spinning liquid and the obtained microcapsule compounded phase-change material of step 2, extrude, obtained modified viscose fiber after mixing through spinnerets, for subsequent use;
Step 4, parts by weight according to ultraviolet curing acrylic ester adhesive 70-80 part, microcapsule compounded phase-change material 5-7 part, take the microcapsule compounded phase-change material that ultraviolet curing acrylic ester adhesive and step 2 are obtained, be mixed to get composite adhesive, composite adhesive is coated on polyacrylonitrile fibre, through UV-irradiation, obtain modified acrylic fibre, for subsequent use;
Step 5, polyster fibre is put into Cement Composite Treated by Plasma instrument, vacuumizing and use oxygen treatments applied 0.5-1.5h, is then in the solution of 20-35% polyethylene glycol at mass fraction by the polyster fibre direct impregnation processed, at the temperature of 25-30 DEG C, soak 6-7h, taking-up is dried, and then uses Ar plasma treatment, processing time is 1-2.5min, power is 100-200W, and pressure is 50-60Pa, after process, with distilled water ultrasonic cleaning 6-8min, after drying, obtained modified polyester fibre, for subsequent use;
Step 6, polyamide 6 and polyethylene glycol are placed according to the mass ratio of 50-90:10-50 the formic acid that mass fraction is 98%, 1.5-2h is stirred at the temperature of 30-40 DEG C, form the even spinning solution that mass fraction is 14-17%, spinning is carried out by electrostatic spinning machine, spinning solution flow velocity is 0.2-0.4ml/h, nozzle diameter is 1-1.2mm, obtains modified nylon fiber, for subsequent use;
