Yarn, yarn forming process, protective textile, knitting method and equipment

Abstract

The present invention relates to a yarn and a yarn forming process, further relates to a protective textile produced by using the yarn and a knitting method therefor, and additionally relates to textile equipment for knitting the protective textile. The present invention discloses a yarn, wherein a core filament of the yarn uses a tungsten wire, which is covered at the center of an outer-layer yarn. A protective textile knitted by using the foregoing tungsten-wire yarn may be obtained by using single-yarn knitting, or by using double-yarn knitting by mixing another yarn. A single shuttle or two-shuttle knitting of the textile equipment may be used in the knitting method. Technical effects of the protective textile are that the protective textile knitted by using the tungsten wire as a core filament has a higher protection level, is lighter and thinner, better fit hand skin, and is operated more flexibly.
