Description

Fabric with enhanced comfort properties

The invention relates to a fabric intended for use in the manufacture of clothing products, such as outerwear, dresses, overcoats, trousers, etc.

We know a wear-resistant fabric and repeated dynamic stresses (RO 122306), made of 100% cotton spun yarns, folded and twisted, with a fineness between Nm 17/3 - Nm 40/3, with single yarn twist 400 - 800 torso / m and twisting of 200 - 500 răs / m, with doubling 2-3, the mass of the fabric being between 260 640 g / m ² , which can be used to make workwear or for leisure.

The disadvantage of this fabric is that it is not comfortable enough, does not allow moisture transfer and is not flexible enough during use in the form of clothing.

There are also fabrics for outerwear (RO108584, RO105489, RO105490) made of wool, wool and polyamide, wool and polyester yarn, with different ties or thicknesses, having a mass between 50 g / m ² - 400 g / m ² .

These fabrics have the disadvantage that they wear easily due to the rupture of the fiber ends and are loaded with ν2 Ο 1 1 - Ο 1 1 8 8 - 2 1 -11- 2011 particles of impurities or grease, thus causing an improper appearance.

The problem solved by the invention consists in establishing the fibrous composition, the texture of the fabric, the structure of the yarns used and the finishing treatment, so as to ensure a compact fabric, with the consistency and draping necessary to ensure comfort and moisture vapor transfer.

The fabric with enhanced comfort properties, according to the invention, eliminates the mentioned disadvantages by having in the warp spun yarns of wool, wool and polyester, with the torsion of 400 ... 800 tors / m, doubled and twisted with

300 .. .500 ras / m, of fineness Nm 20/2 ... 50/2, in weft spun yarns of wool, angora mohair and viscose or polyester (made according to patent No. 116020), with the twist of

400 .. .800 torso / m, doubled and twisted with 300 ... 500 răs / m, of fineness Nm 20/2 ... 50/2, with double warp connection, having two identical faces, in the canvas structure, diagonal, or atlas, which are reinforced together by some warp yarns, twisted in relation to four warp yarns and one warp yarn, the raw fabric having the densities between 20 ... 40 yarns / cm in the warp and 12 ... 20 threads / cm in weft and the mass of 150 ... 400 g / sqm, the raw fabric is finished by commonly known processes, and to increase the wear resistance it is treated by

ν ² Ο 1 1-01188-2 1 -11- 2011 surface application of products made of substances with hydrophilic and antistatic role based on glycols and polytetrafluoroethylene.

The invention has the following advantages:

- the fabric is easy to make and make into clothing products;

- easy to maintain, having the property to be chemically cleaned or washed in organic solvents by commonly known processes;

- ensures long-term use due to surface protection with products made from hydrophilic and antistatic substances based on glycols and polytetrafluoroethylene.

- due to the composition of the yarn, finishing by humidothermal treatments and application of products made of hydrophilic and antistatic substances based on glycols and polytetrafluoroethylene, the fabric becomes stable, pore size is reduced and evenly distributed on the fabric surface, touch and flexibility are improved.

- The following are three examples of embodiments of the invention.
