Description

[Technical Field]

[0001] This invention relates to the field of textile glove technology, specifically, to a cold-weather protective antibacterial glove. [Background Technology]

[0002] When winter arrives in cold regions, the frigid natural environment easily leads to frostbite and damage to people's hands, ears, face, and feet. To avoid frostbite, people usually wear gloves, hats, earmuffs, and other insulating gear, which provide good insulation. However, for people working or engaging in strenuous exercise in cold conditions, while gloves provide warmth, the inside of the gloves, in a sweaty and enclosed environment, can easily breed a large number of bacteria, thus damaging the skin on the hands.

[0003] Chinese utility model patent (application number: 2019203491643) discloses a self-heating, antibacterial, and warm glove that facilitates writing in cold seasons. The glove body includes a glove body with vertical zipper structures on the inner sides of the thumb and index finger to meet the writing needs of the user. The glove body is composed of a multi-layer structure, consisting of a light-generating outer layer, a moisture-absorbing and heat-generating middle layer, and an antibacterial inner layer. This achieves the purpose of providing warmth while inhibiting the growth of microorganisms and protecting health.

[0004] Chinese utility model patent (application number: 202021026109X) discloses a cold-weather glove with nylon and graphene fibers, relating to the field of glove technology. It includes a waterproof layer, a heating layer, a heat-absorbing layer, a fabric, and an antibacterial layer, with the bottom of the waterproof layer fixedly connected to the top of the heating layer. This cold-weather glove with nylon and graphene fibers prevents rainwater from entering through the waterproof layer, provides heating, effectively absorbs heat to prevent heat loss, and the nylon fibers, velvet, rubber, and sponge in the fabric provide effective warmth. The elastic band and drawstring prevent cold air from entering, enhancing warmth and reducing frostbite. The antibacterial layer, composed of silver ion antibacterial fibers, bamboo fiber, graphene fiber, and spandex, effectively combats bacteria and reduces damage. The abrasion-resistant layer prevents wear, and the plush and cashmere texture provides a comfortable feel and effective warmth, while the antibacterial properties reduce bacteria and prevent bacterial invasion.

[0005] Most existing cold-weather protective gloves focus on thermal insulation, with less attention paid to the antibacterial properties of the glove material itself and its performance in various harsh environments. Therefore, this invention addresses the issue of cold-weather protective antibacterial gloves by incorporating antibacterial particles, resulting in excellent antibacterial properties, as well as advantages such as chemical resistance, abrasion resistance, and a long flexural life. [Summary of the Invention]

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cold-weather protective antibacterial glove.

[0007] The objective of this invention is achieved through the following technical solution:

[0009] Antibacterial high-strength polyethylene fiber, its raw material composition percentage is as follows:

[0010] 5-10% of core-shell structured shallow porous microspheres loaded with PSCN

[0011] Polyethylene particle balance

[0012] PSCN consists of phosphorus and sulfur co-doped carbon nitride nanosheets.

[0013] The core of the core-shell structured shallow porous microspheres is made of glass microspheres, and the coating layer is made of chitosan.

[0014] The mass fraction of PSCN-loaded core-shell structured shallow porous microspheres in antibacterial high-strength polyethylene fibers is 6-8%.

[0015] PSCN-loaded core-shell structured shallow porous microspheres are obtained by mixing PSCN and core-shell structured shallow porous microspheres through grinding; wherein:

[0016] The mass fraction of PSCN in PSCN-loaded core-shell shallow porous microspheres is 10-20%.

[0017] The mass fraction of PSCN in PSCN-loaded core-shell shallow porous microspheres is 14-16%.

[0019] (1) Mix various raw materials and melt granulate them to obtain antibacterial high-strength polyethylene;

[0020] (2) The antibacterial high-strength polyethylene prepared in step (1) was used to prepare antibacterial high-strength polyethylene fiber by wet spinning.

[0021] Compared with the prior art, the positive effects of the present invention are:

[0022] The antibacterial high-strength polyethylene fiber of this application is characterized by its low fiber density (0.97 g / cm3), allowing it to float on water; its strong energy absorption capacity, resulting in outstanding impact and cut resistance; its resistance to chemical corrosion and abrasion, and its long flexural life; and its excellent antibacterial properties due to the addition of antibacterial particles.

[0023] The elastic fiber of this application is prepared by partially melting thin crystals at temperatures close to or below the melting point without reducing the molecular weight, and still exhibits good elasticity and long-term stability after aging for 330 days.

[0024] A cold-weather protective antibacterial glove is made of poly[(R)-3-hydroxybutyric acid-co-(R)-3-hydroxyvalerate] elastic fiber and antibacterial high-strength polyethylene fiber through warp knitting; it combines elasticity and strength.
