Claims15
A composite yarn having one or more covering yarns covering a core yarn,
- wherein the core yarn is a slit yarn including an ultrahigh molecular weight polyethylene (UHMWPE) layer;
- and a heat-resistant coating layer formed on one surface of the UHMWPE layer, and
- the core yarn has a width of 0.5 to 3 mm.
A method of manufacturing a composite yarn, comprising:
- S1) applying twisting to a core yarn, which is a slit yarn including an ultrahigh molecular weight polyethylene (UHMWPE) layer;
- and a heat-resistant coating layer formed on one surface of the UHMWPE layer, through a drawing process;
- S2) weaving a first covering yarn into the core yarn of step S1) while applying twisting to the core yarn;
- and
- S3) weaving a second covering yarn into the woven yarn of step S2) while applying twisting to the woven yarn,
- wherein the second covering yarn is woven in the opposite direction to the first covering yarn.
