Description

The group of utility models relates to light industry, in particular to hosiery with a trace, such as:

socks, half-hoses (knee-highs), stockings, tights, etc., made on automatic knitting equipment.

From the point of view of design, an analogue of both versions of the proposed product can be a sock made of natural wool, in which sections of the heel, lower part of the track and toe are connected externally and internally to layers of felt material (US 4255819, class А41В 11/02, published 03/17/1981 )

A well-known product is characterized by increased heat-shielding properties, however, among its disadvantages include excessive thickness and complexity in the manufacture of a compacted trace of the toe.

In addition, as you know, products made from natural fibers (cotton, linen, wool), having a number of hygienic and / or heat-saving advantages over products made from artificial or synthetic fibers, are more susceptible to the damaging effects of various bacteria and pathogens.

A method has been developed for modifying a polymer thread with an antimicrobial additive based on biogenic silver ions that inhibit the growth and prevent the growth of fungi of gram-positive and gram-negative bacteria and mold, and, as a result, the formation of an unpleasant odor and the destruction of the product itself. Additive resistant to bacteria is added to the mass of threads, and not to their surface, so it retains its effect even after repeated washing, and also eliminates the possibility of migration

additive with threads on human skin, which is essential to exclude allergic reactions.

The yarn obtained as a result of such processing has the following trade names: Prolen Siltex and Prolen Bodyfresh. The last of these threads is a special thread modified with an antimicrobial additive, consisting of tested combinations of aromatic compounds that are resistant to bacteria and fungi.

These threads were developed with the aim of making them underwear and bedding, as well as clothing for active sports.

In addition, the thread Prolen Siltex used in the manufacture of selected as the closest analogue of both versions of the proposed utility model of a hosiery with antimicrobial properties, described in patent RU 64481, class. A41B 11/00, published July 10, 2007.

The technical result of the utility model is to increase the operational, in particular strength, characteristics of the product while ensuring the creation of a massage effect in order to enhance the effect on the human skin of threads treated with antimicrobial composition.

The specified technical result is achieved in a utility model due to the following set of features.

A hosiery product having a trace, for example, such as socks, in contrast to leggings that do not have a trace, is characterized in that in it, according to the first embodiment of the product, at least such areas as: the heel, the lower part of the track and toes made by plush weaving with the location (formation) of plush loops from the wrong (inner) side of the product.

For this option, it is possible to complete the entire product or most of it with plush weaving with the formation of plush loops on the wrong (inner) side of it.

According to the second option, the hosiery of the above assortment has a tubular shape, including a board, pagolenok and a toe, while the plush weave is made with the arrangement (formation) of plush loops on the wrong (inner) side of at least such parts as: a toe.

For both variants of the proposed product, this plush weave is made of yarn, at least part of which includes synthetic thread or fiber, modified with an additive with antimicrobial action. The specified additive may contain, for example, silver ions or tested combinations of aromatic halogen-containing compounds.

As synthetic threads or fibers can be used: polypropylene, or polyester, or polyacrylonitrile, or polyamide threads or fibers.

The synthetic thread is made predominantly textured, and such a thread or fiber is multifilament (microfiber).

The proposed options for hosiery can also be made of blended yarn, including, in addition to synthetic yarn or fiber, natural and / or artificial fiber. Said natural fiber may be made of cotton, and / or kapok, and / or linen, and / or silk, and / or wool. Mentioned artificial fiber can be made of viscose or acetate silk.

The proposed product options are mainly made double-faced weaving based on the smooth surface.

Comfort in the wear of the proposed hosiery assortment is achieved due to the fact that the hydrophobic primer facing the body, for example, polypropylene thread, skips

moisture, removes it to the upper layer, consisting of a cover thread made of hydrophilic, for example, cotton or viscose yarn, which absorbs moisture and brings it out, ensuring dry legs during wear of the product.

In addition, plush weaving allows you to increase the strength and wear-resistant properties of the product.

The thread proposed for the manufacture of the claimed product is made of synthetic fiber based on polypropylene (PP), polyacrylonitrile (PAN), polyethylene terephthalate (PET - polyester, polyester) or polyamide (PA) modified with an additive with silver ions (analogue is Prolen Siltex thread) characterized by a number of positive properties. These include: high elasticity and abrasion and tear strength. So the abrasion resistance of a polypropylene yarn is at least 2.5 times higher than that of cotton or wool.

Compared to other types of fibers, this fiber has a higher modulus of elasticity, due to which the products made from it perfectly retain their shape and restore it even after prolonged exposure to an external force, so they do not wrinkle and are distinguished by their shape stability. The specified thread is characterized by a low specific gravity, for example, a polypropylene thread is about 2 times lighter than a cotton or viscose thread.

The moisture absorption index of a polypropylene yarn is almost zero (0.01% at a relative humidity of 65% and a temperature of 20 ° C).

The threads of the proposed synthetic fibers are resistant to acids and alkalis, as well as oxidizing agents and reducing agents.

And finally, the most sensitive (allergen-dependent) people can wear knitwear made of these chemically inert fibers, because these fibers do not react to chemicals,

arising from sweat. They prevent the growth of bacteria, mold and pathogens.

A chemical fiber product retains a small electric charge, which has a positive effect on the human body and is able to maintain the desired temperature in contact with skin, as has low thermal conductivity.

Polyamide fibers include a whole group of synthetic fibers, including kapron, nylon, silon, etc. Modern polyamide microfibers provide, for example, better air exchange even compared to cotton.

Polyamide fiber, in comparison with, for example, polyester fiber, is more form-resistant and wear-resistant, but the latter, like polypropylene fiber, also resists microbial damage and also has the function of removing moisture.

The outer side of the proposed product, as already noted, can be made of threads based on natural, artificial or mixed fibers.

Natural fiber yarns have the following advantages. Cotton fibers are characterized by: high hygiene due to moisture-absorbing and breathable properties, as well as hypoallergenicity. Wool fibers are characterized by: low thermal conductivity, hygroscopicity and moisture absorption, as well as maintaining the climatic conditions necessary for the body.

The outer side of the proposed product can also be made of artificial fiber obtained from natural macromolecular compounds, such as, for example, regenerated cellulose produced from tree wood (pine) or the stems of some plants, such as bamboo or soy. Viscose obtained as a result of processing bamboo or soy raw materials is characterized by high moisture and air permeability, elasticity,

antimicrobial effect, as well as strength and durability. In addition, this material does not harm the environment, being a biodegradable material.

The experiments confirmed the prolonged manifestation of the antibacterial properties of the above fibers. So after fifty washes, the product, which included bamboo fiber, did not lose its antibacterial properties.

In the production of the proposed hosiery assortment products for forming the outer layer of the product, the integumentary thread can be produced from yarn containing a mixture of the above-mentioned natural and artificial fibers. It largely depends on the purpose and season of use of the products.

So, in the autumn-winter period, yarn from a mixture of chemical fibers and wool can be used, and in the summer period from a mixture of chemical fibers and cotton and / or viscose.

An example of the product according to the first embodiment.

The following is an example of making men's socks from cotton yarn (50.7%) in combination with polypropylene textured yarns multifilament with silver ions (49.3%). The toe is made of double-faced weaving, a 3: 1 rapport with longitudinal stripes with a plush patterned weave on the basis of the smooth surface, with knitting of the high heel, heel, lower part of the track and the toe with plush weaving.

The bead section is made with double-faced weaving 1: 1 rapport with the laying of a spun latex thread through a number of knitting.

Knitting areas of the high heel, heel, lower part of the track and the toe with plush weave provides softness and comfort in wearing.

Using in a sock about 50% of multifilament yarns improves such hygienic properties of the product as: air permeability, vapor permeability and hygroscopicity.

Textured polypropylene treated with an additive containing silver ions, filaments (NIPT), due to the structure of polypropylene, allow steam and moisture to be removed from the skin to the upper layer of the sock, where moisture is absorbed by cotton yarn, making the foot of the foot dry.

Silver ions protect the feet from fungal diseases, bacteria, counteract infections, improve foot hygiene and reduce the unpleasant odor of sweat.

These socks have a silky neck and are recommended as a spring - summer assortment.

For the manufacture of the proposed product, a two-cylinder two-system round-hobbing machine (GAMMA model 209/106, class 10) is used, and a one-needle three-thread overlock (Overlock, 208, 208 D) is used to form a seam and process the edges of the product.
