Description

The solution of the invention is suitable for use on fabrics intended in particular for clothing of athletes in which rapid sweat transport from the body to the absorbent layer of the fabric is desirable.

The object is an integrated fabric having a higher sweat transport, formed from at least two layers comprising a hydrophobic backing, a so-called diffuse hygiene layer and a hydrophilic facing, so-called absorbent layer, connected to the diffusion hygiene layer by a plurality of binding sites. SUMMARY OF THE INVENTION The invention is based on the fact that the binding sites distributed in the fabric in accordance with the specified order consist of absorbent wick forming yarns containing hydrophilic fibers and passing through the thickness of the fabric from the absorbent layer to the surface of the diffuse sanitary layer. Absorbent wicks consist of yarns in which at least a proportion of cotton and / or viscose superabsorbent fibers of modified viscose are present. The wicks are on the free surface of a diffuse hygienic layer in the form of dots formed by connecting loops or eyelets.

BACKGROUND OF THE INVENTION The present invention relates to an integrated fabric having a higher sweat transport formed from at least two layers and comprising hydrophobic and hydrophilic fibers. The fabric is particularly suitable for sportswear, both underwear and outerwear.

The functional requirements of sportswear are as versatile as the sport itself. They depend largely on the fabric construction and the textile material used. There is a difference whether a fabric, warp or weft knit is used, and also the relationship in which the weaves are used, for example in terms of stability, breathability, thermal insulation and sweat transport. This last property depends mainly on the combination of the usable material and the weave, or the construction of the fabric.

The problem of sweat production and transport occupies an important place as a decisive factor in assessing the pleasant feeling of wearing sportswear. When sweat fills the space between skin and clothing, it causes discomfort such as damp, wet, cold, sticky feelings that hinder the free movement of the body and, in extreme cases, reduce the performance of the athlete or endanger his health. Textile sheets that absorb sweat while drying quickly are designed to:

a) transport sweat out of the skin as quickly as possible,

(b) absorb sweat as quickly as possible,

(c) transfer sweat to ambient air.

One of the latest development types are so-called integrated textiles with a hygienic function. These include, in particular, a flat fabric and a hygienic layer, known from the invention under No. 226 626, consisting of two layers most commonly knitted and interconnected by knitting to achieve a more efficient function in terms of clothing physiological properties and thus to increase the utility value of a product made of this fabric ·

Its main characteristics are that its skin-backing side is formed from a hydrophotic diffusion sanitary layer with polypropylene fibers extending, while the cheek tree is a hyo-absorbent layer, with absorbent absorbent fibers such as cotton. or wool or a mixture thereof with viscose fibers

All of the aforementioned inventions outside the invention according to Czechoslovak AO No. 228 828 essentially disclose double-layer knitted fabrics, wherein they consist of staple fibers or synthetic threads arranged so that the synthetic material touches the skin as new as possible, in other words predominantly in the face side. whereas h / drooile material predominates in the backsheet. these known fabrics do not solve or, at best, unsatisfactory, manage moisture transport.

The scientific research assumptions and the praise confirm that the so-called integrated knit transports very low sweat in gaseous form, i.e. in the form of overheated vapors. · Condensed sweat, i.e., dripped sweat under direct contact of liquid sweat with the ddooile face layer. The athlete's dipper reaches the back of the fabric on the wet skin of the athlete's body. This causes the hydrophobic layer to leak into the h / drooile layer and thus also to transport the dripping of sweat, which is then completely spontaneous.

A detailed analysis of the current state of the art and based on the numerous knowledge gained from the development and use of the just described known textile fabric after the Czechoslovak AO No. 228 828 shows the moonnot how to further transport liquid sweat from the skin to the absorption layer and thereby improve the functional properties of the textile fabric. to eliminate some of its disadvantages in that it transports dripped sweat under pressure, tettilia to the body of its wearer.

The result of this work is an integrated fabric exhibiting high sweat transport.

This integrated fabric eliminates the disadvantages of the above-described fabrics, being formed of at least two layers and comprising a hydrophobic backing, a so-called diffuse sanitary napkin, and a hydrous facing, so-called absorbent layer, which is connected to the diffusion sanitary napkin by the binding sites. The subject matter of the present invention is that the binding webs, which are embedded in the fabric in accordance with a predetermined order, consist of absorbent wick yarns containing dierous fibers and passing through the thickness of the fabric from the absorbent layer to the surface of the diffuse sanitary layer. Absorbent wicks consist of yarns in which at least they consist of cotton and / or viscose and / or superabsorbent fibers of blue-viscose viscose, the wicks being on the free surface of a diffuse hygiene layer in the form of dots formed by loops or loops. Sealing of absorbent wicks on the surface of a diffuse sanitary layer It may be DC, preferably at least two wicks per square centimeter of surface and a sanitary layer consisting of yarns that hydrophilic hydrophobic staple fibers or filaments, especially polypropylene fibers. Especially suitable for the diffusion sanitary layer are yarns formed from endless shaped polypropylene fibers, in particular shaped by a non-restraint twist or printing jet. The absorbent layer comprises cotton and / or viscose and / or woolen and / or other hydrous fibers, the absorbent layer being single or double; in the latter case, the cell sub-layers are the same or different from one another and / or structurally. The absorbent layer and the diffusion sanitary layer may be formed of knitted fabric, knitted fabric, knitted fabric or interlock, but the absorbent layer may also be formed of a nonwoven fabric, particularly in the form of a sublayer in the second embodiment of the absorbent layer.

The main advantage of the integrated textile according to the invention compared to the known textiles described above lies in the creation of absorbent wicks from the threads of the binding sites. The effect of absorbent wicks in draining dripped sweat from the surface of the diffuse hygiene layer is surprising. Dripped sweat, not connected, rushes to absorbent wicks, which rapidly enter the absorbent layer.

Absorbent wicks, aptly termed them, make the circumference of the liquid sweat not only from the surface of the diffuse hygienic layer, but also from their surroundings within the thickness of the layer, thereby expanding it and thereby enhancing its function of insulating the absorbent sweat-soaked layer from the skin.
