Description

TECHNICAL AREA

The present utility model relates to the technical field of protective cut yarns, in particular a tungsten filament yarn and its textiles.

STATE OF THE ART

The wrapped metal wire yarn on the market is that the steel wire is used as the core yarn, which is covered with other fibers such as spandex yarn, nylon yarn, high-strength, high-modulus polymerized, ultra-high molecular weight polymerized polyethylene filament, etc., thereby forming a special yarn to achieve one or more of good abrasion resistance, tear resistance, puncture resistance, cut resistance and other properties, and its textiles even reach the cutting protection class 5 the EU standard EN388, but these yarns and textiles also have defects such as poor water resistance, poor flexibility, poor flexural strength and susceptibility to deformation after washing, etc.

The American association for the material has currently updated the standard for cut protection gloves and introduced the standard ANSI / ISEA105: 2016 (cutting classes from A1-A9) in order to make the cut protection concept more detailed and standardized.

With respect to the ANSI / ISEA105: 2016 standard, the prior art includes PE, steel wire, basalt, glass fiber, fireproof Kevlar fiber, Dyneema and other series of cutting protection yarns. It has been proven by practice that a number of negative effects will occur when the above fibers are processed into gloves, such as unstable cutting degree, easy-to-break fiber, etc., which leads to allergic phenomena of the hand skin, in addition, the gloves a number of problems that they are not washable and the gloves are relatively thick and do not feel good.

The Chinese patent CN1273662C discloses a cut resistant composite yarn with glass fiber and metal wire components, wherein at least one bundle of the first metal wire is wound on the fiber core yarn along the direction of the first metal wire, and wherein at least one bundle of the first non-metallic, non-high performance fiber cover yarn along the direction of the first cover yarn the first metal wire covers. The yarn has good cut resistance. The shortcomings of the yarn are that it is not washable, has poor flexibility and bending strength, and is prone to warping after washing.

Because of this, there is an urgent need for a yarn which has excellent properties such as washing resistance, flexibility, flexural strength, resistance to deformation during washing, abrasion resistance, tear resistance, cut resistance, puncture resistance, etc., and a textile which is woven with this cut-resistant yarn, to develop.
