Description

The utility model relates to light industry, in particular to hosiery, such as: socks, stockings (socks), leggings, stockings, tights, leggings, gaiters, etc., made on automatic knitting equipment.

As you know, products made from natural fibers (cotton, linen, wool) have several, including hygienic, advantages over products made from artificial or synthetic fibers, however, in some cases they are subject to the destructive effects of various bacteria and pathogens . Stains and smell on such products are only external manifestations of the presence of these microorganisms.

Currently, a method has been developed for modifying a polymer filament with an antimicrobial additive based on biogenic silver ions or tested combinations of aromatic compounds that are resistant to bacteria and fungi of gram-positive and gram-negative bacteria and mold, and, as a result, an unpleasant odor and ultimately destruction the product itself. The bacteria-resistant additive 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 of the additive from the threads to the 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.

These threads were developed with the aim of making them underwear and bedding, as well as clothes for active occupation

sports. At the same time, they can be successfully used in the assortment of hosiery.

As the closest analogue of the claimed utility model, a hosiery product made of smooth plated weaving based on the smooth surface, the ground thread of which is made of synthetic fiber with silver ions, and the cover thread is made of natural or artificial fiber, or a mixture thereof (RU 64481, CL A41B 11/00, published July 10, 2007).

A well-known product is characterized by increased resistance to microorganisms harmful to humans, however, it is not sufficiently wear-resistant, since the integumentary thread included in it is made of fibers characterized by low physical and mechanical properties.

The technical result of this utility model is to increase the operational properties of the proposed product hosiery assortment, primarily its durability, due to the introduction of chemical fibers into the coating thread, which are known to be characterized by increased strength, wear, light and heat resistant properties, and also have elasticity, fatigue endurance and resistance to repeated bending and abrasion, which, along with the possibility of additional processing of these waves windows with an antibacterial composition will increase the operational characteristics of these products and enhance the antibacterial effect. This is especially true for such a representative of hosiery and knitwear as socks, which a person wears, as a rule, together with shoes.

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

Knitted hosiery is formed on machinery and is made predominantly smooth plated

weaving, made mainly on the basis of the smooth surface. The ground thread, placed on the wrong side of the product, is predominantly textured from synthetic material and treated with an antimicrobial composition, for example, modified with an additive containing biogenic silver ions or tested combinations of aromatic compounds that are resistant to bacteria and fungi, and the integumentary thread placed on the front side of the product is made of blended yarn, including chemical fibers, which can also be modified with an additive containing m biogenic silver ions or combinations tested aromatic compounds having resistance to bacteria and fungi.

A synthetic material for forming a filament can be made on the basis of polypropylene, or polyethylene terephthalate, or polyamide, or polyacrylonitrile.

Polypropylene, or polyester, or polyamide, or polyacrylonitrile fibers can be used as chemical fibers for forming the integumentary yarn.

Blended yarn of the integumentary yarn may include natural and / or artificial fibers.

Natural fibers of the integumentary thread can be made of cotton and / or kapok, and / or linen, and / or wool.

Artificial fibers of the integumentary thread can be made of viscose or acetate silk.

The linear density (number) of the yarn of the integumentary thread is in the range of 250 Tex × 1 ÷ 8.3 Tex × 1 (4/1 ÷ 120/1) or 125 Tex × 2 ÷ 8.3 Tex × 2 (8/2 ÷ 120 / 2).

Comfort in the wear of the proposed hosiery assortment is achieved due to the fact that facing the body

hydrophobic soil, for example, polypropylene thread, letting moisture pass it into the upper layer, consisting of a cover thread made mainly of hydrophilic, for example, cotton or viscose yarn, which absorbs moisture and brings it out, ensuring dry legs during wear products, while for hardening the product, chemical fibers are introduced into the yarn of the coating thread.

Double knitwear also improves the strength and wear-resistant properties of the product.

The thread proposed for the manufacture of the claimed product made of synthetic material and the chemical fibers themselves are based on polypropylene, polyethylene terephthalate (lavsan, polyester, polyester), polyacrylonitrile (acrylic) or polyamide, and are modified with an additive with silver ions (analogous to Prolen Siltex thread) , or an additive containing tested combinations of aromatic compounds that are resistant to bacteria and fungi (similar to Prolen Bodyfresh) and are 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. Comparative indicators of the elastic moduli of different threads are presented on the graph (figure 1).

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 (figure 2).

As can be seen from the graph (figure 3), the moisture absorption index of the polypropylene filament is almost zero (0.01% at a relative humidity of 65% and a temperature of 20 ° C).

Comparative indicators of moisture removal for threads from different materials are presented in the graph (figure 4). As can be seen from the drawing, this indicator for polypropylene yarn is the highest and is about 4 mm / s, which is almost 3 times higher than the same indicator for woolen or cotton yarn.

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, since these fibers do not react to chemicals that arise as a result of perspiration. They prevent the growth of bacteria, mold and pathogens. So in the graph (figure 5), the curve "x" shows an increasing increase in the number of bacteria over time for the product made from traditional threads, and the curve "y" shows the stabilization after 1.5 hours of using the product from synthetic threads the number of bacteria, the level of which 2 times lower than the first product.

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 a low thermal conductivity (see Fig.6).

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, is more form-resistant and wear-resistant, however, the latter, as well as polypropylene fiber, is well resistant to microbial damage and also has the function of removing moisture (see figure 3).

The outer layer of the proposed product, as already noted, can be made of yarn, including, along with chemical fibers, threads based on natural, artificial fibers or mixtures thereof.

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.

Kapok is a fiber of white or yellowish-white color, extracted from the fruits of the so-called. cotton tree. It is characterized by high elasticity and low specific gravity. Kapok is 6 times lighter than cotton. Due to its natural density (0.35 g / cm ³ ), kapok is one of the lightest fibers in the world. Kapok is highly resistant to bacteria and mold. This fiber contains natural bitterness that naturally repels moths and ticks. The fiber consists of about 80% of the air, which gives natural thermoregulation. Due to its great lightness and short fiber length (2-4 cm), the kapok is considered to be non-spinning fiber and is used, as a rule, in combination with cotton. Kapok is anti-allergenic and since it is a naturally growing raw material, it decomposes completely upon disposal.

The outer layer 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 some stems

plants, for example, bamboo or soy. Viscose obtained from the processing of bamboo or soybean 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 made from yarn containing a mixture of the above-mentioned natural, artificial and chemical fibers. The percentage of these fibers for each product may vary. It largely depends on the purpose and season of use of the products.

So in the autumn-winter period, yarn made from a mixture of wool with chemical fibers can be used, and in the summer period, cotton and / or rayon can be used in a mixture with synthetic fibers, which increase the strength and wear resistance of the product.

Also within the framework of the proposed solution, it is proposed to use yarn from a mixture of cotton fiber with kapok in the outer layer of the product in a combination of 85% to 15% (No. 4/1 ÷ 120/1 or 4/2 ÷ 120/2).

Said blended yarn consists, for example, of high-quality, hand-picked cotton in combination with wild-growing kapok. The combination of ultralight kapok fiber with high-quality cotton gives products from this blended yarn extraordinary lightness and silkiness, as well as high moisture capacity.

The tubular part of the sock, in addition to the smooth surface, can have a two-face, two-part, jacquard or press weave.

For the production of the tubular part of the proposed socks, a single-cylinder round-hobbing machine (model OZDSR 14-6) is used, and for forming a seam and processing the edge of the product, a one-needle three-needle overlock is used (Overlock, 208, 208 D).

The following is an example of the manufacture of men's socks, the cover thread of which is made of yarn containing natural fibers, such as:

cotton and kapok, and ground - made of polypropylene with silver ions (percentage of raw materials in the product: cotton - 42%; kapok - 10%; NPPT -48%).
