Embodiment 1

[0016] A radiation-proof and antibacterial fabric is prepared by interweaving warps and wefts perpendicularly to each other. The warp is a radiation-proof and anti-bacterial blended yarn, and the weft is a nylon fiber. Cotton fibers are blended in a spiral twisting manner. The diameter of the anti-radiation antibacterial blended yarn is 51-53 μm, the diameter of the nylon fiber is 46-48 μm, the warp density is 70 threads / cm, and the weft thread density is 54 threads / cm.

[0017] The preparation method of anti-radiation antibacterial fiber is as follows:

[0018] (1) 7 parts by weight of lead tungstate was dried at 55°C for 3 hours, then ball-milled for 8 minutes and added to 8 times the volume of absolute ethanol, and 0.7 parts of dodecyl trimethyl bromide was added. Ammonium, utilize the ultrasonic treatment of 46KHz for 35min, then filter and dry;

[0019] (2) Disperse 7 parts of lead tungstate obtained in step (1) into 70 parts of absolute ethanol, and then add 11 parts of...

Embodiment 2

[0024] The preparation method of anti-radiation antibacterial fiber is:

[0025] (1) 7 parts by weight of lead tungstate was dried at 55°C for 3 hours, then ball-milled for 8 minutes and added to 8 times the volume of absolute ethanol, and 0.7 parts of dodecyl trimethyl bromide was added. Ammonium, utilize the ultrasonic treatment of 46KHz for 35min, then filter and dry;

[0026] (2) Mix 7 parts of lead tungstate obtained in step (1) with 18 parts of ethylene glycol, react under the action of 0.07 part of ethylene glycol antimony at 203 ° C, 0.18 MPa, 150 rpm in a nitrogen atmosphere for 5 hours, and then add 110 parts of terephthalic acid and 8 parts of chlorogenic acid, continue to react for 3h, when the water output reaches 98% of the theoretical value, vacuumize to 68Pa, then react at 265°C for 3h, cool down, break the vacuum, and discharge;

[0027] (3) The anti-radiation antibacterial fiber is prepared by melt spinning the result of step (2), wherein the spinning temper...

Embodiment 3

[0030] The preparation method of anti-radiation antibacterial fiber is:

[0031] (1) 7 parts by weight of lead tungstate was dried at 55°C for 3 hours, then ball-milled for 8 minutes and added to 8 times the volume of absolute ethanol, and 0.7 parts of dodecyl trimethyl bromide was added. Ammonium, utilize the ultrasonic treatment of 46KHz for 35min, then filter and dry;

[0032] (2) Disperse 7 parts of lead tungstate obtained in step (1) into 70 parts of absolute ethanol, and then add 11 parts of methacrylic acid monomer, 5 parts of samarium methacrylate, 0.07 part of azobisisobutyronitrile to it , introduced nitrogen protection, then reacted at 72°C and 280rpm for 3h, cooled, filtered, dried at 63°C for 4h, then dried at 92°C for 3h, ball-milled to a particle size of 50-300nm to obtain lead tungstate-methyl Samarium-based acrylate complex;

[0033] (3) Mix 7 parts of the lead tungstate-samarium methacrylate compound obtained in step (2) with 18 parts of ethylene glycol, an...

Abstract

The invention discloses an anti-radiation antibacterial fabric, which specifically relates to the technical field of textiles. The prepared anti-radiation antibacterial fabric has greatly improved anti-radiation performance due to the addition of anti-radiation antibacterial fibers, and has excellent antibacterial performance, which is resistant to Escherichia coli The antibacterial rate of methacrylic acid and Staphylococcus aureus can reach more than 99%; the use of methacrylic acid monomer and samarium methacrylate under the action of an initiator undergoes a polymerization addition reaction on the surface of lead tungstate to form a layer of film structure, A carboxyl-rich lead tungstate-samarium methacrylate complex was obtained, which greatly promoted the interfacial adhesion of lead tungstate to polyester substrates.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a radiation-proof and antibacterial fabric. Background technique [0002] Due to the progress of society, people's demand for fabrics is not only fashionable and warm. With the further development of electrical equipment technology, radiation can be seen everywhere around us. Whether it is mobile phones, computers, printers or microwave ovens for home use, a certain amount of radiation will be generated, especially for pregnant women, the elderly and the elderly with weak resistance. Children are more harmed, so it is of great practical significance to develop fabrics with anti-radiation effects. [0003] Patent CN 104957815 B discloses a radiation-proof antibacterial fabric and a preparation method thereof, which has good antibacterial performance. However, silver-plated fiber filaments are used for warps, which not only has high cost and complicated process, but also has poor...
