Embodiment 1

[0021]Soak a 15cm×15cm cotton fabric in a soap solution with a concentration of 2g / l and a temperature of 50°C for 30 minutes, then rinse it repeatedly with clean water and iron it dry; put the washed cotton fabric in parallel into the plasma The reaction generator is about 1cm away from the magnetron, vacuumize the system to 2Pa, inject argon, and then vacuum-inject argon, repeat three times. Slowly feed argon gas afterwards, and finally treat the cotton fabric for 8 minutes under an argon pressure of 45Pa and a discharge power of 200W, so as to initiate argon microwave low-temperature plasma on the cotton fabric and generate free radicals on its surface; the molar ratio 1:1 2-acrylamide-2-methylpropanesulfonic acid (AMPS) and N-isopropylacrylamide (NIPA) monomers, that is, 43.241 grams of AMPS and 23.6156 grams of NIPA are mixed in the container with 8.3477 grams The sodium hydroxide is neutralized, then add and account for 1% of the molar weight of the monomer mixture, name...

Embodiment 2

[0024] The argon pressure when the argon microwave low-temperature plasma is initiated in Example 1 is changed to 60Pa, and the total weight of the monomer mixture and the crosslinking agent is changed to 15% of the total weight of the aqueous solution, that is, the addition of AMPS and NIPA The amount changed to 25.9446 grams and 14.1693 grams respectively, the amount of sodium hydroxide added became 5.0086 grams, the amount of Bis added became 0.3861 grams, and the water required was 224.4914 grams. Other conditions remained unchanged. The weight gain rate of environmentally responsive smart textile fabrics after graft polymerization for 40.

Embodiment 3

[0026] The argon pressure when the argon microwave low-temperature plasma is initiated in Example 1 is changed to 60Pa, and the molar weight of Bis in the monomer mixture is changed to 0.5%, that is, the addition of AMPS and NIPA becomes 43.448 grams and 23.7287 grams respectively. gram, the addition of sodium hydroxide becomes 8.3877 grams, the addition of Bis becomes 0.3233 grams, 194.1123 grams of water is required, and other conditions remain unchanged, the weight gain rate of the environmentally responsive smart textile fabric after graft polymerization is 45.

Abstract

The invention relates to an environment-response intelligent weave fabric and relative preparation. Wherein, adding the fabric which is induced by argon microwave low-temperature plasma to generate free group on surface, into the dual monomer solution of 2-acrylamide-2-methanesulfonic acid and N-isopropyl acrylamide that contains N and N'-methylene dual acrylamide cross linker to process graft polymerization reaction, while the bath ratio is 1:40, to graft the dual intelligent gel on the fiber macromolecule of fabric, to attain said inventive product. When the invention is dry, it has no difference from general fabric, but when it is wet, the gel will adsorb water to expand and block the slits between fibers, to reduce the water and gas permeability of fabric, and avoid outer penetrating into the inner layer of fabric to stop heat emission. The invention can be used to produce army waterproof clothes, heat-accumulation temperature adjustable special clothes, etc.

Description

technical field [0001] The invention relates to a textile fabric and a preparation method thereof, in particular to an environment-responsive intelligent textile fabric and a preparation method thereof. Background technique [0002] Traditional clothing mainly maintains the normal temperature in the body by controlling the heat radiation, heat conduction and heat convection between the human body and the external environment. This is the most basic and primitive function of clothing to keep out the cold. Since ancient times, the performance of textiles for clothing has almost entirely depended on the properties of the fiber material itself, so clothing has not been able to get rid of the single function of keeping out the cold and heat preservation for a long time. However, since the late 1970s, especially since the early 1980s, with the improvement of living standards, people's understanding and requirements for clothing have changed a lot, and gradually changed to the "com...
