Abstract

Textile fabric for clothings, in particular fabric for shirts or blouses, wherein the textile fabric comprises mutually orthogonally crossing warp threads and weft threads, the threads being made of stainless steel fibres and textile fibres blended together and spun into a mixed yarn, the steel fibres measuring 6 to 12 mu m in diameter and constituting 6 to 15 % of weight of the mixed yarn, wherein threads with left turns and right turns in warp direction and/or in weft direction are alternating in order to avoid a curling tendency in spite of the presence of the steel fibres.

Description

TEXTILE CLOTHING FABRICS

The invention relates to a textile fabric for clothing, more specifically to a textile fabric for shirts and blouses, comprising at right angles to the intersection of intersecting basic and weft threads made from a spun blend of textile fibers and stainless steel fibers spun with the first.

EP 0 383 059 discloses a textile fabric of the aforementioned type, wherein steel fibers measuring 6 to 10 μτη in diameter and 10 to 15 wt.% Are mixed with cotton fibers to form blended yarn so that the thread density in the fabric it is 18 to 20 threads / cm in the warp and weft direction, while the yarn fineness is 30 to 50 tex. With this fabric structure, the fabric provides a safety screen against 20 to 40 dB of electromagnetic radiation at 10 GHz. Such safety shielding against electromagnetic radiation is sufficient for particular pacemaker carriers to eliminate the influence of electromagnetic radiation on the function of the pacemaker. The fabric thus obtained is still rather rugged and therefore not best suited to the manufacture of such shirts and blouses whose appearance is indistinguishable from everyday cotton shirts and cotton blouses with comparable wearing comfort. The content of steel fibers may also result in the tendency of the fabric to wrap, which is disadvantageous in the manufacture of clothing products.

Thus, it is an object of the invention to provide a textile fabric for a garment of the aforementioned type, which tends to be minimal in twisting even with a higher degree of fineness of yarn and with a achieved screening effect comparable to that of the known protective fabric.

According to the invention, for a textile fabric for clothing, more specifically for a fabric for shirts and blouses, comprising at right angles to each other, intersecting basic and weft threads made of stainless steel fibers and textile fibers intermixed and spun into a compound yarn, wherein the steel fibers measure 6 to 12 gm in diameter and represent a content of 6 to 15 wt.%, preferably 8 to 12 wt.% of mixed yarn, the object of the invention is solved by the fact that the threads are alternately in the warp and / or weft direction left-handed and right-handed threads.

In this way, even in the case of yarns with a high degree of fineness, the curvature of the fibers is significantly reduced despite the content of steel fibers and the high degree of twisting of the filaments. It can be used in the weft direction and in the warp direction alternately neither with the opposite twist, or to be used only in the warp or in the opposite direction. by twisting.

Thread rates are preferably 550 to 800 turns / m, most preferably 600 to 800 turns / m.

The fabric according to the invention preferably exhibits a yarn fineness in the range of 12 to 36 tex, and preferably in the range of 20 and down to 12 tex for fine blouse for ladies blouses. The density of the weft and warp threads may be 20 to 40 threads / cm. Although it is possible that the number of threads in the warp direction differs from the number of threads in the weft direction, and most often in the warp direction, the number of threads is greater than that in the weft direction, the preferred embodiment of the invention uses a warp thread number equal to the number of threads in the warp direction. vodka direction. It is generally observed that the effect of protective shielding increases in proportion to the number of threads used. At the same time, it is preferable that the steel fibers are spread on the outer surface of the fibers in as many places as possible, in particular at the intersections of the threads, and that there is electrical contact between the warp threads and the weft threads at said intersection points.

Textile fibers are preferably combed cotton fibers or viscose fibers, which may also be spun with mixed yarn or twisted into mixed yarn with other textile fibers. It is also possible to use only textile fibers made of plastic.

For example

In the cotton fabric cotton fabric according to the present invention for the manufacture of men's shirts and ladies' blouses having a yarn fineness of 17 tex, combed cotton fibers were spun into blended yarn with deer fibers so that the combed cotton fibers formed a content of 89% by weight of blended yarn , and the steel fibers have a content of 11% by weight of mixed yarn, with the steel fibers measuring 8 μτη in diameter. In the direction of the warp, we used right-handed threads, and in the weft direction alternately right-handed and left-handed threads, each thread having 780 turns / m. The number of threads in the warp direction was 34 threads / cm and the number of threads in the weft direction was 23.5 threads / cm. The fabric achieved an average shielding effect against electromagnetic radiation of 28 dB at 10 GHz.

The second textile fabric for protective workwear according to the invention used a fineness of 30 tex yarn, combed cotton fibers with steel fibers into a blend yarn, in which combed cotton fibers formed a content of 89% by weight of blended yarn, and the steel fibers formed 11% by weight of mixed yarn, the steel fibers being 8 μτη in diameter. Right-hand threads were used in the base direction, and right-hand and left-hand threads alternately in the weft direction, each with 600 turns / m. The number of threads in the warp direction was 25.5 threads / cm and the number of threads in the weft direction was 24 threads / cm. The fabric achieved an average shielding effect against electromagnetic radiation of 30 dB at 10 GHz.
