Embodiment 1

[0026] Polyvinyl silicone oil (n vinyl / no Si =10%, 500cs) 1g, ethylene glycol-bis(3-mercaptopropionate) 0.25g, benzoin dimethyl ether 0.05g and MQ resin 0.5g are dissolved in 98.20g toluene to make a photosensitive solution, and the knitted cloth is impregnated In the photosensitive solution obtained above for 3 minutes, after the immersion is completed, the knitted fabric is taken out from the photosensitive solution, and the free liquid on the knitted fabric is removed with a rolling mill, and the excess rate is 90%. The uncured components on the knitted fabric are dissolved to obtain a one-way fluid-conducting knitted fabric, and the hydrophobic thickness of the one-way fluid-conducting knitted fabric accounts for 35% of the total thickness. After testing, the moisture transmission time of the knitted fabric is 80s.

[0027] Under the same component conditions, only changing the time of ultraviolet light irradiation can obtain the one-to-one correspondence between the ti...

Embodiment 2

[0029] The terminal vinyl silicone oil (n vinyl / no Si =0.36%, 10000cs) 1g, trimethylolpropane three (3-mercaptopropionic acid) ester 0.84g, benzoin dimethyl ether 0.02g and vinyl POSS 0.5g are dissolved in 97.64g tetrahydrofuran to make photosensitive solution, will Immerse the woven fabric in the obtained photosensitive solution for 5 minutes. After the immersion, take the non-woven fabric out of the photosensitive solution, use a rolling mill to remove the free liquid on the non-woven fabric, the excess rate is 150%, and irradiate the non-woven fabric with ultraviolet light for 5 minutes. Finally, tetrahydrofuran was used to dissolve the uncured components on the non-woven fabric to obtain a unidirectional liquid-conducting non-woven fabric, and the hydrophobic thickness accounted for 50% of the total thickness. After testing, the moisture transmission time of the non-woven fabric is 2 minutes.

Embodiment 3

[0031] The terminal vinyl silicone oil (n vinyl / no Si =3%, 100000cs) 1g, tetrakis (3-mercaptopropionic acid) pentaerythritol ester 0.3g, benzoin ethyl ether 0.02g and vinyl fumed nano silicon dioxide 0.2g are dissolved in 97.64g ethyl acetate and make photosensitive solution, will Immerse the woven fabric in the obtained photosensitive solution for 10 minutes. After the impregnation is completed, take the nonwoven fabric out of the photosensitive solution, use a rolling mill to remove the free liquid on the nonwoven fabric, and the excess rate is 150%, and irradiate the nonwoven fabric with ultraviolet light for 15 minutes. Finally, ethyl acetate was used to dissolve the uncured components on the non-woven fabric to obtain a one-way liquid-guiding non-woven fabric, and the hydrophobic thickness accounted for 95% of the thickness of the textile. After testing, the moisture transmission time of the non-woven fabric is 30 minutes.

Abstract

The invention discloses a preparation method of a Janus type textile. The preparation method of the Janus type textile comprises the following steps of dissolving 1-10 parts by mass of hydrophobic active substance, 0.2-3 parts by mass of thiol reagent, 0.01-0.2 part by mass of initiator and 0.05-2.5 parts by mass of auxiliary agent in 89.7-98.2 parts by mass of solvent to prepare a photosensitivesolution, treating the textile by using the photosensitive solution, performing ultraviolet irradiation on the textile treated by the photosensitive solution for 3-15 min, dissolving uncured photosensitive solution components on the textile treated by the photosensitive solution by using the solvent, and drying the obtained textile to obtain the Janus type textile. The invention provides a methodfor curing macromolecules on the surface of the textile by using sulfydryl / olefin click chemistry, which has the advantages of being non-selective to textile material, good in durability, controllablein modification depth, simple in preparation method, low in cost and suitable for industrial production.

Description

Technical field: [0001] The invention belongs to the technical fields of polymer materials and textile engineering, and in particular relates to a preparation method of Janus-type textiles. Background technique: [0002] Functional textiles refer to fabrics that have certain specific functions in addition to basic functions such as conventional decoration and warmth. Common functions include quick-drying, super-hydrophobic, anti-fouling, anti-radiation, and anti-static. In 2017, the sales volume of the global functional textile market was 50 billion US dollars per year, while the domestic demand for textiles was also around 50 billion RMB. With the development of science and technology and the improvement of social living standards, people's demand for functional textiles continues to increase. It is expected that the market sales will increase by an average of 3.8% per year. New technologies and new products are constantly updated, and the market prospect is good. Unidirec...
