Technology area

Technical solution relates to the technological design of fabric that combines cotton - loop side and synthetic side so that the resulting structure provides a new special function - the moisture away from skin while maintaining comfort and good thermal-insulation properties.

Present condition of technology

Loop fabrics, also known as Terry cloth, are three-dimensional fabrics. The third dimension consists of fabric loops of warp threads above or below the surface of the fabric. Loop fabrics are usually manufactured in two versions:

- Loop fabrics three-weft

- Loop fabrics four-weft

For production the weaving machines for weaving of terry are used. Loop and the basic warp is given from the individual weaver's beam, loops are formed on the warp are created by "non-reaching" of ray during the weaving. Height of the loop is determined by the size of the "non-reaching".

The loop warp has 200 to 800 % gathering. The full stop/reaching is only after the third or fourth brought weft, which takes a loop warp. Loop fabrics with cut loops are similar to velvet and can be called "velor".

The standard loop fabrics are often used in hotel textiles, which includes the following categories: textiles bathroom (dressing gowns - bathrobes), bathroom clothing (sauna towels - kilts, loincloth, slippers), towels, massage pads, etc. and then also for the production of sports textiles (clothing, equipment).

This type of fabric is usually used at home, in hotels, wellness, spa, health services, for sports, fitness, on the beach. According to the methods of use the properties of fabric of this type must fulfill various requirements. Fulfillment of these requirements is ensured by the type of fiber used, fabrics construction, or cut clothing.

The most common requirements (which are sometimes mutually exclusive) are moisture absorption, quick drying, heat insulation - warmth, light weight, drape, minimal pilling, nice touch, non-stick surface, antimicrobial properties, dimensional stability, low wear, contemporary look, easy maintenance.

The standard loop fabrics used most often for towels and bathrobes are made of hydrophilic cotton fibers and provide excellent absorbency and in dry state provide also the warmth. The disadvantage of these traditional materials is the fact that in the wet state the above properties, especially the warmth, decrease rapidly and thereby the user's comfort decreases as well. This results in less outlet of moisture from the skin and worse keeping it dry.

Principle of technical solution

During the construction of material in accordance with this technical solution it is an attempt to achieve these requirements for fabrics:

• moisture from the skin , absorbency

• maintaining the skin's surface in dry

• thermal insulation , warmth

• comfortable feel

• easy maintenance, fast drying, stability maintenance

• low bulkiness

• Modern look The above deficiencies largely solves by the construction of functional loop fabric according to his technical solution.

Its essence is that in its special design it combines two types of materials, hydrophobic synthetic material and a hydrophilic cotton fibers, where synthetic material covers the back surface of the fabric and the staple yarn of hydrophilic cotton fibers creates the inner structure and loop fabric surface, i. e. a front of the end product.

The surface of the backside of the cloth is made up of synthetic length textile. This layer provides output of moisture from the skin, but due to its hydrophobic properties it provides also minimal water absorption. This layer is in direct contact with the skin, it does not absorb water, but it can detract the water from the body (by capillary phenomenon) to the next layer of fabric. At the same time it improves the thermal insulation. It also provides the following functions: it prevents odor, has a nice touch, does not irritate skin mechanically, allows rapid drying of the skin. Synthetic material is contained in the fabric from 10 to 90 %.

The outer loop surface and internal structure of the fabrics, that consist of staple yarn 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.

Functional fabric loop consists of the basic warp of the nominal fineness of yarn tex 20 to 150, then the loop warp of the nominal fineness of yarn tex from 20 to 150 , weft cotton yarn of the nominal fineness of yarn tex 20-150 and weft synthetic length fabric of a nominal fineness tex 30 - 700. The warp thread count is in the range 180 to 450 threads / 10 cm and weft thread count is in the range 100 to 350 threads / 10cm. Gathering of loop warp loop is in the range 150 - 1000 % and the fabric surface weight is between 300 to 900 g/m2.

Based on the above composition these advantageous properties of the loop fabric according to the invention are achieved: ^>

- in the wet state the thermal conductivity is on the synthetic inner side lower i. e. - this surface takes away from the body less heat, i. e. it cools less in the wet state than the outer side of cotton

- the process of soaking of small drops into the fabric from the innner side of the synthetic material is performed in the way that the moisture spreads faster through body of synthetic material and it is transmitted to the cotton outer side of textile List of pictures on the drawings

Technical solutions will be further illustrated by a drawing in which Figure 1 shows a longitudinal section of functional loop fabric from which the structural composition of the fabric according to the invention is evident.
