Multi-functional cotton and linen socks

Technical Field

The invention relates to the technical field of sock spinning, in particular to a multi-functional cotton and linen sock.

Background

Socks are indispensable necessities in daily life of people, and with the improvement of the material culture level of people, functional textiles become one of the development trends of future textile industry, the quality requirements of people on close-fitting clothes are higher and higher, the requirements on warmth retention, attractiveness and comfort and functionality are required, and the socks and fine denier fiber textiles, non-woven fabrics, composite materials, environment-friendly materials and the like jointly form the great trend of future textiles.

The existing socks mostly adopt fiber materials such as terylene and spandex as yarns to weave the socks, and have the following defects in several aspects: (1) most of the skin care products are in a splicing structure, the yarns are split due to long-term abrasion, the colorful yarns are matched with the crocheting patterns, but the yarn ends on one side contacting with the skin are complicated, so that the skin is greatly rubbed and pressed, especially for the delicate skin of children, the yarn ends are easily wound around the toes due to the negligence of parents, and even the tightening marks and the wounds are generated; (2) the fiber materials such as terylene and spandex have poor air permeability, and bacteria are easy to breed when feet sweat, so that beriberi is caused, and the health is not facilitated; (3) the heel and the toes are not firm and are easy to wear and damage, so that the socks are discarded, the purchase cost is increased, and unnecessary textile waste is generated; (4) in the process of taking off, socks and foot skin are difficult for droing, take place to roll up easily on the one hand and influence accomodating, and on the other hand is a burden to waist sick person, and difficult socks that take off are even more.

In order to solve the problem of poor air permeability, the cotton and linen socks appear on the market, are sweat-absorbent and air-permeable, and have good comfort level, but the cotton and linen socks have poor elasticity, are easy to wrinkle, have poor wear resistance, are not enough in color fastness, are easy to fade, affect the appearance and are not durable. Therefore, the sock has important research significance for further improving the structure and the performance of the existing sock.

Disclosure of Invention

The invention provides an antibacterial wear-resistant multi-functional cotton-linen sock which is good in air permeability, seamless in sewing, high in color fastness and capable of preventing rolling, and aims to solve the problems that the existing sock is poor in air permeability, has a thread end on a skin contact surface, is not firm, is easy to fall off and is easy to roll.

Hydrogels (hydrogels) are gels that use water as the dispersion medium. The water-soluble polymer with a reticular cross-linked structure is a cross-linked polymer which is formed by introducing a part of hydrophobic groups and hydrophilic residues into the water-soluble polymer, wherein the hydrophilic residues are combined with water molecules to connect the water molecules in the reticular structure, and the hydrophobic residues swell when meeting water. Is a polymer network system, has soft property, can keep a certain shape, and can absorb a large amount of water. The preparation method comprises the steps of uniformly dispersing nano antibacterial materials with the particle size of 20-50 nm in hydrogel to obtain modified hydrogel, coating the modified hydrogel on the surfaces of the branch fibrilia, compounding the modified hydrogel with the main fibrilia containing silver fibers to obtain modified cotton-linen blended yarns, and integrally and seamlessly knitting the modified cotton-linen blended yarns into the multi-element functional cotton-linen socks. The antibacterial principle of the modified hydrogel is as follows: the specific surface area increases greatly as the particle size of the material decreases. Particles with a size of 5nm, the volume percentage of the surface is 50%, and at a size of 2nm, the volume percentage of the surface increases to 80%. After the nano antibacterial material is dispersed in the hydrogel, the nano antibacterial material has a large specific surface, the bonding state is seriously mismatched, and a plurality of active centers appear, so that the nano antibacterial material has extremely strong adsorption capacity. The nano particles have extremely strong capturing capability for oxygen atoms and oxygen free radicals which promote substance putrefaction, alkane molecules which generate other peculiar smells and the like, so that the nano particles have the functions of corrosion prevention and bacteria resistance.
