Claims (14)

  1. A method of manufacturing a cut-resistant composite yarn structure (170), comprising: spinning first staple fibers (134) over a first cut-resistant core filament (132) to build a first core-spun yarn (135a); winding a first covering layer (138), comprising a first filament, over a second cut-resistant core filament (136) to build a covering yarn (139) spinning second staple fibers (134) over a third cut-resistant core filament (132) to build a second core-spun yarn (135b); and winding a second covering layer (140), comprising a second filament, over the first core-spun yarn (135a), the covering yarn (139), and the second core-spun yarn (135b) to bind the first core-spun yarn (135a) and the second core-spun yarn (135b) with the covering yarn (139), thereby forming the cut-resistant composite yarn structure (170).
  2. The method of manufacturing the cut-resistant composite yarn structure (170) of claim 1, wherein the first cut-resistant core filament (132) comprises one of basalt material, steel material, or a steel alloy material.

  4. The method of manufacturing the cut-resistant composite yarn structure (170) of any preceding claim , wherein the third cut-resistant core filament (132) comprises one of basalt material, steel material, or a steel alloy material.
  5. The method of manufacturing the cut-resistant composite yarn structure (170) of any preceding claim, wherein the second filament comprises at least one of fire retardant regenerated cellulose, polyimide, para-aramid, or polyacrylonitrile (PAN).
  6. The method of manufacturing the cut-resistant composite yarn structure (170) of any preceding claim, wherein the second filament comprises at least one of polyester, PE series-polyester, polyethylene, high performance polyethylene (HPPE), high molecular weight polyethylene (HMWPE), and regenerated cellulose.
  7. The method of manufacturing the cut-resistant composite yarn structure (170) of any preceding claim, wherein the first staple fibers (134) comprise at least one of polyester, PE series-polyester, polyethylene, high performance polyethylene (HPPE), high molecular weight polyethylene (HMWPE), regenerated cellulose, fire retardant regenerated cellulose, polyimide, para-aramid, or polyacrylonitrile (PAN).
  8. The method of manufacturing the cut-resistant composite yarn structure (170) of any preceding claim, wherein the second staple fibers (134) comprise at least one of polyester, PE series-polyester, polyethylene, high performance polyethylene (HPPE), high molecular weight polyethylene (HMWPE), regenerated cellulose, fire retardant regenerated cellulose, polyimide, para-aramid, or polyacrylonitrile (PAN).
  9. The method of manufacturing the cut-resistant composite yarn structure (170) of any preceding claim, further comprising winding a third covering layer (152) over the first core-spun yarn (135a).
  10. The method of manufacturing the cut-resistant composite yarn structure (170) of claim 9, wherein the third covering layer (152) comprises at least one of polyester, PE series-polyester, polyethylene, high performance polyethylene (HPPE), high molecular weight polyethylene (HMWPE), regenerated cellulose, fire retardant regenerated cellulose, polyimide, para-aramid, or polyacrylonitrile (PAN).
  11. The method of manufacturing the cut-resistant composite yarn structure (170) of any preceding claim, further comprising winding a fourth covering layer (162) over the second cut-resistant core filament (136).
  12. The method of manufacturing the cut-resistant composite yarn structure (170) of claim 11, wherein the fourth covering layer (162) and the first covering layer (138) are wound opposite to each other.
  13. The method of manufacturing the cut-resistant composite yarn structure (170) of claim 11, wherein the fourth covering layer (162) and the first covering layer (138) are inter-wound at the same time.
  14. The method of manufacturing of any of claims 11 to 13, wherein the fourth covering layer (162) comprises at least one of polyester, PE series-polyester, polyethylene, high performance polyethylene (HPPE), high molecular weight polyethylene (HMWPE), regenerated cellulose, fire retardant regenerated cellulose, polyimide, para-aramid, or polyacrylonitrile (PAN).

Description

BACKGROUND Yarns may be manufactured by combining separate threads of filaments, for example by winding one thread or filament on top of one or more other threads or filaments. The yarn may be formed by twisting the one or more threads or filaments around each other. A composite yarn may be composed of a plurality of other yarns. Yarns may be interlocked or woven to create continuous cloths. Different knitting structures may be formed as a jersey knit structure, a plating knit structure, a rib knit structure, or other knit structure. Yarn-based cloths may be used to make garments such as gloves, sleeves, shirts, pants, socks, coverings, and other cloths. United States Patent Application Publication No. US 2004/0091705 A1 relates to fire retardant and heat resistant yarns, fabrics, and other fibrous blends that incorporate one or more fire retardant and heat resistant strands comprising oxidized polyacrylonitrile and one or more strengthening filaments such as metallic filaments (e.g., stainless steel), high strength ceramic filaments, or high strength polymer filaments. United States Patent Application Publication No. US 2008/0098501 A1 relates to a cut-resistant glove, which is formed of a composite yam comprising a core and a covering layer formed by wrapping a covering fiber around the core, the core being composed of a metal thin wire and an attending yarn comprising a filament yarn, the surface of which is coated with a rubber or a resin.
