Embodiment 1

[0016] A radiation-proof and antibacterial fabric, which is made by interweaving warps and wefts vertically, the warp is radiation-proof and anti-bacterial blended yarn, and the weft is nylon fiber, wherein the radiation-proof and anti-bacterial blended yarn contains 65% of radiation-proof and anti-bacterial fibers, and the balance is Cotton fiber, the two are blended in a helical cross-twisting method, the diameter of the anti-radiation and 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] Wherein the anti-radiation antibacterial fiber preparation method is:

[0018] (1) Dry 7 parts by weight of lead tungstate at 55°C for 3 hours, then ball mill for 8 minutes and add it to 8 times its volume of absolute ethanol, and add 0.7 parts of dodecyl trimethyl bromide Ammonium, using 46KHz ultrasonic treatment for 35min, then filtered and dried;

[0019] (2) Dis...

Embodiment 2

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

[0025] (1) Dry 7 parts by weight of lead tungstate at 55°C for 3 hours, then ball mill for 8 minutes and add it to 8 times its volume of absolute ethanol, and add 0.7 parts of dodecyl trimethyl bromide Ammonium, using 46KHz ultrasonic treatment for 35min, then filtered and dried;

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

[0027] (3) The product obtained in step (2) is melt-spun to obtain anti-radiation and antibacterial fibers, wherein the spinnin...

Embodiment 3

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

[0031] (1) Dry 7 parts by weight of lead tungstate at 55°C for 3 hours, then ball mill for 8 minutes and add it to 8 times its volume of absolute ethanol, and add 0.7 parts of dodecyl trimethyl bromide Ammonium, using 46KHz ultrasonic treatment for 35min, then filtered and dried;

[0032] (2) Disperse 7 parts of lead tungstate obtained in step (1) into 70 parts of absolute ethanol, then add 11 parts of methacrylic acid monomer, 5 parts of samarium methacrylate, and 0.07 parts of azobisisobutyronitrile , pass through nitrogen protection, then react at 72°C and 280rpm for 3h, cool, filter, dry at 63°C for 4h, then dry at 92°C for 3h, and ball mill to a particle size of 50-300nm to obtain lead tungstate-formazan Samarium acrylate complex;

[0033] (3) Mix 7 parts of the lead tungstate-samarium methacrylate compound obtained in step (2) with 18 parts of ethylene glycol, under the action of 0.07 ...

Abstract

The invention discloses a radiation-proof antibacterial fabric, and particularly relates to the technical field of textiles. According to the prepared radiation-proof antibacterial fabric, due to addition of radiation-proof antibacterial fibers, the radiation-proof property of the fabric is greatly improved, the antibacterial property is excellent, and the bacteriostasis rate on escherichia coli and staphylococcus aureus can reach 99% or above; and a carboxyl-rich lead tungstate-samarium methacrylate complex is obtained by polymerization addition reaction of methacrylic acid monomer and samarium methacrylate on the surface of lead tungstate under the action of an initiator to form a film structure, so that the interface binding force of the lead tungstate and a polyester substrate is greatly promoted.

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 the current 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 for work or microwave ovens for home use, a certain amount of radiation will be produced, especially for pregnant women, the elderly and those with weak resistance. Children are more injured, therefore, the development of fabrics with radiation protection has important practical significance. [0003] Patent CN 104957815 B discloses a radiation-proof antibacterial fabric and its preparation method, which has good antibacterial performance, but its warp is made of silver-plated fiber filaments, which not only has high cost and complicated process,...
