Description

 Two-layer warp knitted elastic knitted fabric, knitted hosiery and yarn for them.

FIELD OF TECHNOLOGY

The group of inventions relates to light industry, namely to knitwear production, in particular, to two-layer warp knitted knitwear with elastic properties.

Such canvases can be used both in the textile and, mainly, in the medical industry in the manufacture of heating products, namely, belts and bandages, including on the knees, lower legs, elbows and other parts of the body.

The invention also relates to hosiery and knitwear, such as: socks, stockings (socks), leggings, stockings, tights, leggings, gaiters, etc., made on automatic knitting equipment and the composition of the yarn for these products and the above-mentioned fabric.

BACKGROUND

Known elastic bandage containing a frame in the form of a pipe made of warp knitted two-layer knitted fabric, the layers of which are connected by elastic threads, while one of the layers is made of cotton yarn, and the second of down yarn, with a ratio of 1 :( 1-0.6 )

The surface density of the known bandage is in the range from 300 to 500 g / m. The specified bandage is described in patent RU 2211052, class. A61L 15/00, published on 08.27.2003.

The main disadvantage of the known bandage is the lack of micromassage effects on the active points of the human body, since the material of one of the layers is soft downy yarn. In addition, it is not possible to conclude from the description of the patent which of the layers of the bandage is intended to fit to the human body, on which the achievement of the massage effect largely depends. Also, the well-known bandage is characterized by insufficient surface density, which adversely affects its operational properties, in particular, strength.

A double knitted fabric is known, consisting of two layers, one of which is made in the form of a warp knit in several rows of natural or from a mixture of natural and chemical threads, and the other layer is made in the form of a weaving on the basis of an eraser, while some of the loops of this layer are additionally contains elastomeric polyurethane threads (SU 1148917, class D04B 1/00, 04/07/1985). It should be noted that the described knitted fabric is intended for the manufacture of glove products.

The disadvantage of this fabric is the possible shift of two heterogeneous layers during operation of the product made from it, since the bond between the layers is not strong enough, which is undesirable for products such as belts and bandages. In addition, the extensibility of the known fabric is significantly limited, which also impairs its durability and other operational properties in relation to medical products made of such a fabric. None of the described analogues can be selected as the closest analogue of the proposed invention for the object "full", since the object of patenting the first is the bandage, and not the canvas, and the canvas of the second analogue is not elastic.

An analogue of the invention for objects “products” and “yarns” can be called a hand-knitted product, in particular socks or leg warmers, including a tubular knitted part, looped rows of which are made of threads containing natural fibers, which, as the rows of loops are knitted in different parts products used alpaca wool, and / or dog wool, and / or linen fiber, and / or nubuck (RU 33378, CL A41B 1/00, published on 10/20/2003).

The main disadvantages of the known solution can be attributed to the fact that only one part of the product is formed from one or another type of wool or fiber (the composition of the yarn is not described), therefore, the operational properties of this product are heterogeneous, which can lead to a decrease in its durability. In addition, in the known product is not ensured the achievement of the massage effect.

SUMMARY OF THE INVENTION The technical result of the invention is to increase the operational properties of the proposed products and yarn from which they are made, in particular elasticity, strength and wear resistance, as well as to reduce volatility, shrinkage and ability to contaminate, in particular, due to the natural yarn included in the product from wool of camel, yak, Angora or Kashmir goats. Also, the operational properties of the products are improved compared to the named analogue due to the implementation of the machine viscous product, which contributes to a more uniform distribution hinged rows and columns on the product, compared to hand-knitted.

In addition, the proposed products and yarn are characterized by good warming ability, and the addition to the composition of the products or the execution of their whole yarn containing camel hair or yak wool, promotes the creation of micromassage effects on the active points of the foot or, in the embodiment of the product in the form of leg warmers, calf areas of the human foot. It should also be noted that by mixing the following types of natural wool, the effect of mixing down fibers of one type of wool with transition and / or core fibers of other types of wool is achieved, which gives the product and yarn the specified operational effect. In addition, the objective of the proposed invention is to create knitted fabrics suitable for the manufacture of mainly medical devices such as warming belts and bandages, and the technical result consists in increasing their operational, in particular, massage properties, in comparison with known products of this kind, as well as elasticity, without deterioration of form stability, strength, heat saving, reduction of self-sustainability, shrinkage and ability to pollution. In addition, the proposed fabric is technologically advanced in manufacture, and the addition of sheep wool to the composition of the yarn made from natural fibers can increase its softness.

Also, when mixing different types of natural wool, the effect of mixing down fibers of one wool with transitional and / or core fibers of other types of wool, which gives the canvas a specified operational effect.

The proposed elastic knitted fabric is characterized by the following features: it contains two layers interconnected by knitting using elastic threads and made of yarn containing only natural fibers or a mixture of natural and chemical fibers, while the natural fibers of the first layer yarn

(facial, working) canvases are made of wool from a representative of the camelid family, namely: camel and / or alpaca, and / or llama, and / or vicuna, and / or guanaco.

Natural fibers of the yarn of the first layer of the fabric may additionally contain sheep wool, the fineness of which lies in the range of 18 ÷ 45 microns.

One or both layers of the canvas can be made with fleece. The second (reverse) layer of the fabric is made of pure or mixed cotton yarn, and in one of the variants of the fabric is made with fleece. Polymeric yarns, for example, polyester textured yarn and / or PAN and / or acrylic, are used as chemical yarns and fibers in the manufacture of the web, and elastic yarns are made of natural latex braided with a polyester yarn. In addition, acrylic, PAN, as well as polyester yarn can be included in cotton yarn in various combinations.

As an example, the fabric according to both variants of the invention may consist of 40 ÷ 50% yarn from camel wool and 40 ÷ 45% cotton yarn, the first layer for the first option may be made of yarn containing from 5% to 100% natural camel wool, and the second layer contains natural or mixed cotton yarn. The first layer may additionally contain no more than 70% PAN or acrylic.

Also, the fabric according to both variants of the invention can consist of 40 ÷ 50% alpaca and merino yarn and 40 ÷ 45% cotton yarn, while its first layer for the first variant is made of yarn containing 5% ÷ 100% natural alpaca wool and not more than 95 % yarn from fine sheep's wool - merino, and the second layer consists of natural or blended cotton yarn.

The first layer may additionally contain from 10% to 70% acrylic.

Cloth is made of warp knitted with weft closed chain-ducks.

The surface density of the canvas is in the range of values of ZOO ÷ bOO g / m ² . The canvas is made in the form of a wide ribbon, while the elastic threads form rows of weft with a distance between them (pitch) of about 0.5 cm, and along the longitudinal edges of the tape, the elastic threads form rows of weft made with a distance between them (pitch) of about 0.3 see. The technical result of the invention for the object "product" is achieved through the use of the following set of features. Knitted hosiery includes a tubular part formed on machinery, formed by a weaving or double-faced, or two-sided, or jacquard or press weaving of loop rows and columns made of threads containing yarn made only from natural fiber or from a mixture of natural and chemical fibers, while natural fiber consists of wool selected from a number of: camel family wool, Kashmir goat wool, Angora goat wool, yak wool and from any combination of these types of wool among themselves.

The outer and / or inner side of the product is mainly made with fleece, which contributes to an additional increase in the warming ability of the product due to the creation of an air gap and / or massage of the body.

In addition to the main component, natural fiber may additionally contain sheep wool with a fineness of 18 ÷ 45 μm, selected in accordance with well-known principles of blending for wool and wool mixture. As a chemical fiber, not more than 70% acrylic (bulk yarn) and / or PAN (polyacryl non-thread yarn) and / or PA (polyamide synthetic textured yarn) can be used to increase the wear resistance, elasticity and strength of products. The product can be made of natural fiber, containing from 5% to 100% unpainted wool of one of the representatives of the camelid family, for example, camel wool and not more than 70% of a chemical fiber, such as: PAN and / or PA, and / or acrylic.

According to another embodiment of the product, natural fiber may contain the same amount of unpainted alpaca wool and may further comprise not more than 95% fine sheep wool made from merino (merino wool), and also not more than 70% of the named chemical fiber.

Also, natural fiber according to the following embodiment of the product may contain from 5% to 100% natural alpaca wool and from 10% to 95% fine merino wool.

The technical result of the invention for the object "yarn" is achieved through the use of the following set of features.

The yarn contains natural fiber or a mixture of natural and chemical fibers, while for the manufacture of the first layer of the fabric, natural fiber is used, consisting of camel from the family of camelids, namely camel and / or alpaca and / or llama and / or wool vicuna, and / or guanaco wool, and for knitted hosiery, natural fiber is used, consisting of wool selected from the following: camel hair, yak wool, Kashmir goat wool, Angora wool ozy or from any combination of the listed types of wool among themselves. Natural fiber yarn according to one embodiment of the invention may further include sheep wool with a fineness of 18 ÷ 45 μm, selected in accordance with Known principles for blending wool and blended yarn.

Chemical fiber can be made of acrylic, and / or PAN, and / or PA. The natural fiber according to an embodiment of the invention can consist of unpainted wool of one of the camelids, for example, alpaca, mainly in combination with merino wool, while it contains from 5% to 100% alpaca wool and up to 95% sheep, for example, merino wool, and it may include up to 70% PAN, and / or PA, and / or acrylic.

The yarn can also consist of 5% ÷ 100% unpainted wool of one of the representatives of the camelid family, for example, camel hair and can include no more than 70% PAN, and / or PA, and / or acrylic.

For example, for the manufacture of hosiery from natural fiber from camel hair, depending on their type and purpose, wool yarn with a number and a linear density of 4/1 - 50/1 (250 Tex x 1 - 20 Tex x 1) or 8/2 - 50/2 (125 Tex x 2 - 20 Tex x 2), consisting of 5% ÷ 100% (mainly 70%) camel natural wool and not more than 70% (mainly 30%) PAN and / or PA.

The technological capabilities of the equipment used for the production of the proposed products make it possible to use yarn entirely made from natural, for example, camel wool.

For the manufacture of hosiery, for example, from a mixture of natural fiber from alpaca and merino wool, also in depending on the type and purpose of these products, wool yarn with a number and linear density in the range of 4/1 - 50/1 (250 Tex x 1 - 20 Tex x 1) or 8/2 - 50/2 (105 Tex x 2 - can be used 20 Tex x 2), consisting mainly of 37.5% acrylic, 37.5% merino wool and 25% alpaca.

The technological capabilities of the equipment used for the production of the proposed products allow the use of yarn entirely made from natural alpaca wool, however, given its scarcity and high cost, this yarn includes from 5% to 100% alpaca wool, up to 70% acrylic and from 10% to 95% fine sheep wool (merino) in any combination thereof.

Products can be made of weaving, double-faced, two-sided, jacquard or press weave. Culinary weaving (regular smoothness) is used for thinner, breathable products.

Two-face (elastic) weave and two-side weave, when the front and back loops alternate depending on the knitting report, are used to form tight-fitting products.

Jacquard weaving, when the loop alternates with a broach and each loop is made of its own color or type of yarn, is used for more dense, colorful products.

Press weaving, consisting of a loop and a sketch, is used to create more breathable lush products. Sheep's wool improves the quality of spinning, retains heat perfectly, practically does not crease, but has the property of falling down.

Cashmere is the most noble type of wool that is obtained from the wool of the Kashmiri goat. Cashmere is susceptible to friction; therefore, pellets quickly form on it.

Alpaca - wool, which is obtained from alpaca (artiodactyl animal of the llama rola). The thin alpaca coat is soft and not susceptible to friction. This type of wool is sometimes confused with mohair, but unlike mohair, alpaca glistens.

Camel hair is thin, medium thickness and thick and perfectly retains heat.

Merino sheep wool is valued for its thin and light hair. Items made from merino wool are soft and elastic. This coat does not irritate the skin and is perfect for children's clothing.

The fiber of mohair (mohair), or angora, is a fiber obtained from Angora goat breeds. The fineness of the fiber depends on age: in young animals, from 25 to 33 microns; in adults - 33-45 microns. The fineness and length of the fiber varies in different parts of the fleece.

Mohair fiber is characterized by softness and smoothness of the surface.

The coat of Angora goats has a very long hair and wear resistance. When mixing different types of natural wool, the effect of mixing down fibers with transition and core fibers is achieved, which give a multiple operational effect. For example, a mixture of coarse camel fibers and downy alpaca or llama fibers leads to the production of raw materials for the production of yarn and subsequently products with desired performance properties, such as with a massage effect with a greater or lesser degree of severity.

Example 2

The fabric can be characterized by the following types of yarn: for the first (front, working) layer, the number of wool yarn can be in the range 4/1 - 32/1 (250 Tex x 1 - 20 Tex x 1) or 8/2 - 50/2 ( 125 Tex x 2 - 20 Tex x 2), consisting mainly of 37.5% acrylic, 37.5% merino wool and 25% alpaca; for the second (reverse) layer - cotton yarn Ne 20/1 (50 Tex x 1), consisting of 70% cotton fiber and 30% polyester yarn. The layers of the fabric are interconnected in a knitted way with polyester textured threads N2N2 60/1 - 54/1 (16.7 Tex x 1 - 18.6 Tex x 1) and latex threads 0.6 mm thick with a weld density of 21 by 10 cm. Group Elongation: 0-40%, 41-100%. The technological capabilities of the equipment used for the production of the proposed fabric allow it to be used for the first (front, working) layer of yarn entirely made from natural alpaca wool, however, given its scarcity and high cost, this yarn includes from 5% to 70% alpaca wool, as well as 50% acrylic and from 10% to 70% thin fleece (merino) in any combination thereof.

The composition of the elastic knitted fabric for the second embodiment of the invention (as a percentage of its constituent components) is presented in table 3.

Technical characteristics of this canvas are presented in table 4.

The above-mentioned elastic knitted fabrics are produced on the basis of the Kamets knitting machine 10, 15 cells. with weaving a closed duck chain (see Fig. l). Cloths are made in the form of tapes with a width of 20 ± 1 cm and 28 ± 1 cm, depending on the purpose of the canvas. The implementation of paintings with such a width allows you to easily and quickly form from them the necessary medical products that have a spatial (tubular) shape. It is enough only after cutting to grind the edges of the future product.

Performing on the longitudinal edges of the canvas connecting stitches in the form of a tape with a more frequent pitch (about 0.3 cm), reduces its extensibility, and, consequently, increases the dimensional stability of products made from this tight during operation, which eliminates the need for adjusting at the edges finished product reinforcing braid. For the production of the tubular part of products, for example, such as woolly socks, a GAMMA 206/59 model two-cylinder knitting circular hosiery machine is used, and a single-needle three-thread overlocking machine overlock 208, 208D is used to form a seam and edge treatment of the product.

The proposed products obtained by machine viscous are characterized by a more even distribution of looped rows and columns over them, and this applies equally to products having different thicknesses, including rather thin ones.

Elastic fiber (textured PA thread) allows you to achieve a better and more dense fit with the product body of the consumer.

Several rows of elastic thread (spandex) made of natural latex, braided with a polyester textured thread, allowing to achieve better fixation of the product on the body of the consumer, are also passed along the edge of the products. The advantages of products made using the above-mentioned natural fiber yarn include the fact that the yarn itself, having an attractive natural color, does not need to be dyed, which positively affects the performance properties of finished products and yarn, in particular, their strength and heat conservation, also about hygienic properties, such as, for example, breathability.

A mixture of wool of Kashmir goats, which have extremely soft and soft-touch wool, mainly white, and yak wool, which is durable and heat-resistant, mainly black or brown, makes it possible to obtain a large number of products with different physical and mechanical properties and yarn. Besides, since the products and yarns are not dyed, it is possible when mixing different types of yarn in the product or the wool of different animals in yarn to obtain products of different colors and yarns that have a natural color.

It should be noted that the camelid family wool has an oblique structure and consists of down, transitional and core fibers.

The fineness of the remaining fibers is 50-75 microns, transitional 30-50 microns, down 18-29 microns.

The yarn obtained from the wool of a camelid family, which includes: a camel and rarer representatives of this family, such as: llama, guanaco, alpaca and vicuna, is somewhat similar to yarn from the wool of yaks and Kashmir goats, while it differs from yarn from sheep wool with higher consumer properties, greater strength, increased gloss, low ability to pick up and contaminate and a characteristic color. For example, the scaly layer of camel hair is very different from the scaly layer of sheep’s wool, and this largely determines the specific properties of camel hair. Flakes tightly cover the bulk of the fiber - the cortical layer, well protecting the fibers from external influences and preventing the penetration of pollution between the flakes. Generalized data on the fineness of fibers of various types of wool of the mentioned rare animals in comparison with similar data on merino sheep wool are presented in table 20. Alpaca fiber has the greatest popularity among textile workers from the animal group: llama, gunaco, alpaca and vicuna. From the point of view of zoology, alpaca belongs to the order Lama Gepus, divided into three branches: llama (lama glama), guanaco (lama guapisoe) and alpaca (lama races). A separate, fourth branch is vicuna (viсugpa). Together, these animals form a family of South American camels, currently living exclusively in the Southern Andes, in the main in the central highland plateau at an altitude of about 4600 m above sea level. The yarn of alpaca wool is very similar in type to the yarn of wool and down of camels (see table 20).

Alpaca gives a very soft, rather long coat of white, gray, black and brown colors. In terms of brilliance, alpaca occupies an intermediate place between the hair of the mohair and the camel. Like llama and camel, alpaca is a type of mixed wool. The fluff is thin, about 15-20 microns; minority core fibers are coarse. The length of the fluff is 80-120 mm, and the spine reaches 300 mm. The fluff does not have a core canal, but in the spine it is presented clearly. The scaly layer is similar in structure to the camel layer. According to its commercial quality, alpaca wool is divided into coarse, medium and thin.

Kashmir fiber got its name from a similar name for the goat breed, which has extremely soft and soft-touch wool, mainly white (brown, light brown, gray Kashmir fiber is much less common), fineness from 12 to 21 microns and a length of 25 to 90 mm.

Kashmir fiber is obtained by combing. The main parameters of down fiber: fineness 11-18 microns, length 25-80 mm; coarse: fineness 30-100 microns, length 40-200 mm.

Sarlik wool or yak wool is predominantly black or brown. The fineness of downy yak fiber is on average 15-17 microns with a length of 4 to 5 cm for young animals and 18-19 microns and 3-3.5 cm, respectively, for an adult population. From one individual, up to 0.5 kg of down and up to 1 kg of coarse (sub-down fiber) is obtained. Yak fiber after the dehairing process (similar to the Kashmir fiber used) is used in the manufacture of blankets and some types of clothing.

Massage effect is achieved in the product by exposure to woolen fibers, for example, from camel hair in combination with merino, from which the hosiery is formed, when worn on the consumer’s body.

Products, which include the above options for wool and their possible combinations, acquire new positive qualities compared with the known knitted products. So, they are characterized along with improved warming and massage properties, increased elasticity, strength and low ability to clotting, which, in turn, increases the durability of products made from them, including those having a medical purpose. It should also be noted that the product, which includes alpaca wool, is softer and does not prick in its effect on the skin and therefore can be used for more delicate areas of the human body or for a more tender and sensitive skin of children. In addition, it does not fade or lose its color during the cleaning and washing of products made from it.

When mixing different types of natural wool, the effect of mixing down fibers with transition and core fibers is achieved, which give a multiple operational effect.

For example, a mixture of coarse camel fibers and downy alpaca or llama fibers leads to the production of raw materials for the production of yarn and subsequently products with desired performance properties, such as with a massage effect with a greater or lesser degree of severity.

The addition of sheep wool to the yarn helps to improve the consumer properties of the product, associated, for example, with an increase in its softness. So, for example, in the production of the first layer of a cloth of camel wool of the second grade (weed-burdock), semi-thin sheep wool can be added to the composition of the yarn.

Massage effect is achieved through the interaction of woolen fibers, from which the front (working) layer of the fabric is formed, with the body of a person, when putting on a belt or bandage. At the same time, the back layer of the fabric, formed from cotton yarn, is outside this medical device, and contributes, along with a sufficiently large distance between the connecting stitches (0.5 cm step), more free penetration through it into the air and / or outward perspiration, which increases hygiene of the product. The canvases, which include the above-mentioned varieties of wool, for example, alpaca and / or camel wool, acquire new positive qualities in comparison with known canvases. So, they are characterized along with improved warming and massage properties, increased elasticity, strength and low ability to clotting, which, in turn, increases the durability of products made from them, including those having a medical purpose.
