Description

Metal fiber hybrid braided shield high conductive cloth

The present invention relates to a shielded highly conductive cloth, and more particularly to a blended yarn comprising ultrafine metal fibers.

According to the vigorous development of the technology industry, various technological products are developing rapidly. For example, while electronics and electrical appliances bring convenience to people, they also generate a large amount of electromagnetic radiation, forcing people to be exposed to various electromagnetic wave threats, such as prolonged exposure. The environment of this electromagnetic wave is likely to cause a decline in immune function, and it may also cause physical adverse effects such as fatigue, tired eyes, shoulder pain, headache, sleepiness and restlessness.

There are many ways to eliminate electromagnetic pollution. Among them, it is very effective to develop anti-electromagnetic radiation clothing. Because of wearing clothes, it will also protect us. China's past anti-electromagnetic radiation fabrics are mainly used in medical, national defense and some special industrial fields, and are mainly made of conductive materials. Because they are too bulky and have a bad hand, they are rarely worn. In view of the above, in order to improve the above disadvantages, a better shielded high-conductivity cloth is needed to improve the soft touch of the conventional electromagnetic wave shielding cloth and the high electromagnetic wave shielding protection function, so as to overcome the above disadvantages.

Therefore, many improvements have been proposed. Such as: Chinese Patent Application No. 00113541.4, 2000, revealing a warp and The metal filament fabric composed of the weft yarns, the metal filament bundle section containing the metal monofilaments having a number of 20-20000, mainly used as a high temperature resistant filter fabric, a conductive fabric, and a shield fabric.

In 2011, National Patent Publication No. 201132818 discloses an environment-friendly high-flame-flame blended conductive fabric comprising a blended yarn of wool and metal fibers and an environmentally friendly flame retardant.

In 2014, the national patent publication No. M481933 discloses a metal fiber blended electromagnetic wave shielding cloth. The weft yarn of the metal fiber blended electromagnetic wave shielding cloth comprises a blended yarn of cotton fiber and metal fiber, and the warp yarn is a microfiber yarn.

Therefore, with the rapid popularization and development of communication products, the problem of electromagnetic radiation in daily life is becoming more and more serious, and there is an urgent need for better anti-electromagnetic radiation protection articles, especially electromagnetic shielding cloths having an ideal shielding effect and a soft touch.

In view of this, the purpose of the present invention is to provide a metal fiber hybrid woven shield high conductive cloth, characterized in that the metal fiber hybrid woven shield high conductive cloth is composed of a warp and a weft.

The warp and weft are woven by a weft woven fabric with a twill weave, and have a soft, good hand and high conductivity metal fiber hybrid woven shielded high-conductivity cloth, and the electromagnetic wave shielding rate of 300MHz, 900MHz, 1800MHz and 2.45GHz electromagnetic waves. ≧99%, with good shielding effect. The metal fiber hybrid braided shielded high-conductivity cloth, wherein the warp yarn is a combed cotton 40-twisted double-strand blended yarn containing a high ratio of ultrafine metal fibers, and the ultrafine metal fiber blend ratio is at least 30%, preferably At least 40%. The weft yarn is a combed cotton 32-unit single-strand blended yarn containing a high ratio of ultrafine metal fibers, and the ultrafine metal fiber blend ratio is at least 30%, preferably at least 40%. Wherein, the metal fiber hybrid braided shield high conductive cloth has a weight in the range of 180-240 g/m ² and has a warp ultrafine metal fiber content of at least 30%, preferably at least 40%. The weft ultrafine metal fiber content is at least 30%, preferably at least 40%.

The second objective of the present invention is to provide a metal fiber hybrid braided shielded high conductive cloth which is woven by a weft woven fabric with a twill weave structure, and has a soft hand and high electrical conductivity.

Another object of the present invention is to provide a metal fiber hybrid braided shielded high conductive cloth, the metal fiber hybrid braided shield high conductive cloth, and the warp yarn is a combed cotton 40 double-strand blend with high ratio of ultrafine metal fiber. The yarn has a superfine metal fiber blend ratio of at least 30%, preferably at least 40%.

Another object of the present invention is to provide a metal fiber hybrid woven shield high-conductivity electromagnetic wave shielding cloth, the metal fiber hybrid woven shield high-conductivity cloth, and the weft yarn is a combed cotton with a high ratio of ultra-fine metal fiber 32 single sheets The blended yarn has a blend ratio of ultrafine metal fibers of at least 30%, preferably at least 40%.
