Embodiment 1

[0025] Let the cotton yarn pass through a corona discharge tube with a voltage of 10,000 volts and a power of 30 watts at a speed of 20 meters per minute, so that free radicals or ions are generated on the cotton yarn and activated. Then enter the temperature is 70 ℃, the weight concentration is 30% bisallyl dimethyl ammonium chloride aqueous solution, react for 25 minutes. Take out and wash off the reaction solution, apply oil and dry to obtain the acrylic fiber grafted with bisallyl dimethyl ammonium chloride. The grafting rate of bisallyl dimethyl ammonium chloride was determined to be 14.6%.

Embodiment 2

[0027] Let the acrylic yarn pass through a corona discharge tube with a voltage of 7500 volts and a power of 25 watts at a speed of 12 meters per minute to activate free radicals or ions on the cotton yarn. Then enter the temperature is 65 ℃, the weight concentration is 25% acrylic acid-N-trimethylethyl ester ammonium chloride aqueous solution, react for 30 minutes. Take out and wash off the reaction solution, apply oil and dry to obtain the acrylic fiber grafted with N-trimethylethylammonium chloride acrylic acid. The grafting rate of acrylate-N-trimethylethyl ammonium chloride was determined to be 18.4%.

Embodiment 3

[0029] Let the nylon filament pass through a corona discharge tube with a voltage of 10,000 volts and a power of 40 watts at a speed of 6 meters per minute, so that the polyester fibers of the polyester yarn are activated by free radicals or ions. Then enter the temperature of 55 ° C, the weight concentration of 50% acrylate-N-trimethylpropanyl ammonium chloride aqueous solution, and react for 24 minutes. Take out and wash off the reaction solution, apply oil and dry to obtain the acrylic fiber grafted with N-trimethylpropanyl ammonium chloride acrylic acid. The graft ratio of acrylate-N-trimethylpropanyl ammonium chloride was determined to be 12.2%.

Abstract

The present invention pertains to a kind of branch grafting textile by positive ion quaternary ammonium radical group, including chemical fiber, yarn or their fabric textiles, and relating to a method of branch grafting positive ion quaternary ammonium radical group through plasma reaction. All the textiles to be treated are first placed in the electric field of electric corona discharge electricity with 3,000 to 12,000 voltages and the power of 10 to 500 watts and enable their surface to produce free radical or ionic radical, then put into double bond quaternary ammonium monomer solution to carry out branch grafting poly-reaction, and branch grafted with quaternary ammonium positive ionic radical group, and finally the modified textiles containing quaternary ammonium positive ionic radical group will be attained after getting rid of non-reaction monomer and going through washing, oiling and drying processes.

Description

Technical field: [0001] The invention is a grafted quaternary ammonium group, which is obtained by grafting cationic quaternary ammonium groups on textiles through plasma activation. Background technique: [0002] Most clothing and home textiles made of natural fibers or conventional chemical fibers are not sterilized. With the continuous improvement of people's living standards, people have higher and higher requirements for clothing and home textiles in terms of aesthetics, comfort, and hygiene. It is hoped that some textiles can have the effect of antibacterial and sterilizing. There are many antibacterial methods for textiles, such as adding antibacterial substances in the process of chemical fiber production, and adding antibacterial substances in the post-finishing method. Antibacterial substances also have a variety of useful metal ions, such as silver, copper, zinc, and the like, and are useful in various medical drugs. Cationic quaternary ammonium salts have a ba...
