Abstract

The essence of this invention is that in its special design it combines two types of materials, hydrophobic synthetic material (2) and a hydrophilic cotton fibers (1), where synthetic material covers the back surface of the fabric and the staple yam of hydrophilic cotton fibers creates the inner structure and loop fabric surface, i. e. a front of the end product. The outer loop surface and internal structure of the fabrics, that consist of staple yam from hydrophilic cotton fibers, mediate the transport of water from the back layer and thus away from the body and it gradually evaporates into the surrounding environment. Material from cotton fibers is contained from 10 % to 90 % in the fabric.

Description

Functional loop fabric

Technical field

The technical solution relates to a technological fabric construction that combines a cotton looped side and a synthetic side so that the resulting structure provides a new special function of wicking moisture away from the skin while maintaining comfort and good thermal insulation properties.

BACKGROUND OF THE INVENTION

Looped fabrics, also called terry fabrics, are three-dimensional fabrics. The third dimension of the fabric is the warp thread loops above or below the base fabric surface. Loop fabrics are most often produced in two versions:

- loop fabrics - see figure 2,

- loop fabrics, four-cornered - see Fig. 3.

Weaving machines for terry weaving are used for production. Loop and base warp is fed from separate rollers, loops on the warp are formed by the so-called lack of beam during weaving. The loop height depends on the size of the stop.

The loop syllabus has between 200 and 800% encounters. The full stop occurs only after the third or fourth clogged weft takes the loop warp with it. Looped fabrics with sheared loops are similar to velvet and can be called velor, see Figure 4.

Standard loop fabrics are most commonly used for hotel textiles, which include the following categories: bathroom textiles (bathrobes - bathrobes), bathroom clothes (sauna bath towels - kilts, loincloths, slippers), towels, bath towels, massage washcloths and the like also for the manufacture of sports textiles (clothing, equipment).

This type of fabric is usually used at home, in hotels, wellness, spa, healthcare, sports, fitness, on the beach. Depending on the application, different requirements are placed on the properties of this type of fabric. Compliance with these requirements is ensured by the type of fibers used, the design of the flat fabric or the cut of the garment.

The most common requirements (which are sometimes mutually exclusive) are moisture absorption, quick drying, thermal insulation - warmth, low weight, drapability, minimal lint, pleasant touch, non-stick surface, antimicrobial properties, shape stability, low abrasion, modern appearance, easy maintenance .

Standard loop fabrics most commonly used for towels and bathrobes are made of hydrophilic cotton fibers and provide excellent absorbency and warmth in the dry state. The disadvantage of these classic materials, however, is the fact that in the wet state the aforementioned properties, especially the warmth, rapidly decreases and thus also the user's comfort decreases. This is associated with a worse removal of moisture from the skin and keeping it dry.

The essence of the technical solution

In the construction of the material according to this technical solution, the aim is to achieve the following fabric requirements:

- moisture wicking, absorbency,

- keeping the skin dry

- thermal insulation, warmth,

- comfortable feel,

- easy maintenance, faster drying, maintenance stability,

- low bulkiness,

-1GB 23466 U1

- modern look.

The above-mentioned drawbacks mentioned in the paragraph "prior art" are eliminated by the construction of a functional loop fabric, according to this technical solution.

Its essence is that in its special construction it combines two types of materials, a hydrophobic synthetic material and a hydrophilic cotton fiber, the synthetic material covering the back of the fabric and the staple yarns of hydrophilic cotton fibers forming the inner structure as well as the loop surface of the fabric .

The surface of the back of the fabric is formed by a synthetic longitudinal fabric. This layer removes moisture from the skin, but at the same time, thanks to its hydrophobic properties, minimal water absorption. This layer has direct contact with the skin, does not absorb water, but can drain it away from the body (by capillary effect) into the next layer of fabric. At the same time, it improves thermal insulation. It also provides the following functions: prevents odor formation, has a pleasant touch, does not irritate the skin mechanically, allows rapid drying of the skin. Synthetic material is present in the fabric from 10 to 90%.

The outer loop surface and the inner structure of the fabric, which consist of staple yarns of hydrophilic cotton fibers, mediate the transport of water from the backing layer and thus from the body and gradually evaporate it into the surrounding environment. The cotton fiber material is comprised between 10% and 90% in the fabric.

The functional loop fabric consists of a base warp in a nominal yarn 20 to 150 tex, a loop warp in a nominal yarn 20 to 150 tex, a weft cotton yarn in a nominal yarn 20 to 150 tex, and a synthetic weft yarn in a nominal fineness 30 to 700 tex. It receives a warp in the range of 180 to 450 threads / 10 cm and receives a weft in the range of 100 to 350 threads / 10 cm. The loop warp meeting is in the range of 150 to 1000% and the basis weight of the fabric is in the range of 300 to 900 g / m ² .

On the basis of the above-mentioned loop fabric composition, the following advantageous fabric properties according to this utility model are achieved:

- the thermal conductivity in the wet is lower on the synthetic inner side ie - this surface dissipates less heat from the body, ie it cools less in the wet state than the cotton outer side,

the process of soaking small drops into the fabric from the inside of the synthetic material is such that the moisture spreads more rapidly through the body of the synthetic material and is transferred to the cotton outer side of the fabric.
