Embodiment 1

[0025] Disperse 2 grams of commercially available iron phthalocyanine in 1000 grams of self-crosslinking polyacrylate emulsion diluted to 1.5% and whose glass transition temperature Tg is -10° C., and stir evenly. Use the method of two dipping and two padding to pad the prepared solution on the cotton knitted fabric, so that the liquid volume is 70% of the weight of the cotton cloth, then dry at 80°C, and then bake at 140°C for 3 minutes. Make it cross-linked and set. That is, a cotton wool cloth containing iron phthalocyanine was obtained. The ammonia elimination rate of the cloth is 72%, and the hydrogen sulfide elimination rate is above 90%.

[0026] Detection method: Put 4 grams of cloth containing the catalyst in a 10-liter plexiglass sealed box with a latex injection window, fill it with odorless fresh air and seal it, inject ammonia or vulcanization through the latex window with a syringe Hydrogen gas so that its concentration is around 100 PPM. Analyze the concentra...

Embodiment 2

[0028] Disperse 1.5 grams of commercially available porphyrin iron in 1000 grams of water-soluble polyurethane solution diluted to 2.5%, and stir evenly. The prepared solution is dipped on the acrylic knitted fabric by two dipping and two rolling methods, so that the liquid amount is 75% of the weight of the acrylic fabric, and then dried at 100° C. to set the shape. That is to obtain the acrylic knitted fabric containing porphyrin iron. The cloth uses the measuring method of embodiment 1 to record the elimination rate of ammonia gas of 64%, and the elimination rate of hydrogen sulfide of 86%.

Embodiment 3

[0030]Dissolve 2.5 grams of sodium iron tetracarboxyphthalocyanine in 1000 grams of water-soluble polyurethane solution diluted to 2%, and stir evenly. The prepared solution is dipped on the polyester plain cloth by the method of two dipping and two rolling, so that the amount of liquid carried is 55% of the weight of the polyester plain cloth, and then dried at a temperature of 100 ° C to set the shape. That is to obtain the acrylic knitted fabric containing iron phthalocyanine. The ammonia elimination rate of the polyester cloth measured by the measurement method in Example 1 is 76%, and the hydrogen sulfide elimination rate is above 90%.

Abstract

This invention relates to a method for coating a coat containing an organic metal catalyst on a fabric by a coating arrangement technology. The arrangement agent is composed of an organic metal catalyst and a resin, the organic metal catalyst is selected from Fe, Co and Mn dissolved or scattered in the coat resin to coat the fabric by the ordinary arrangement technology and dry it to get the fabric with organic metal catalyst.

Description

technical field [0001] The invention relates to a coated fabric containing an organometallic catalyst coated on the fabric through coating finishing technology and its manufacturing and application technology. Background technique [0002] 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 textiles can have the effect of removing odor. People have done a lot of work in this regard, and the current basic way is to add antibacterial substances in the chemical fiber production process; or add antibacterial substances in fabric finishing, so that the fibers or fabrics have a bactericidal and deodorizing effect. Relevant reports on bactericidal and deodorant effects include: Xiao Yaonan, Zeng Hanmin's research progress on antibacterial and deodorant functional fibers (2): Preparation, Materials Science and Engineering, 2001, 2, 80-88...
