Abstract
A cotton denim fabrics and method of making denim fabrics that are soft, smooth, bright and include a low twist multiple, a sizing at the surface of the yarn with a viscosity such that the sizing remains substantially at the surface of the yarn, and a dyed cored wherein an indigo dye penetrates deeply into the core.
Claims10
A low twist, combed, indigo yarn wherein the yarn is a two-ply yarn, comprising:
- a first yarn and a second yarn,
- wherein:
- the first yarn comprises a first yarn count of 7.5/1 Ne;
- and
- the second yarn comprises a second yarn count of 10/1 Ne:
- and
- the first yarn and second yarn comprising:
- a twist multiple between 2.0 and 3.4, inclusive;
- a sizing at the surface of the yarn;
- and
- a dyed core wherein an indigo dye penetrates deeply into the core,
- wherein the sizing remains substantially at the surface of the yarn.
A method of producing a low twist, combed indigo yarn, the method comprising:
- providing combed cotton fibers
- spinning the cotton fibers to produce yarns having a twist multiple between 2.0 and 3.4, inclusive;
- dying the yarns, wherein an indigo dye penetrates deeply into the core to produce a dyed core;
- sizing the yarns using a sizing with a viscosity of sizing chemicals that is such as to keep the sizing substantially at the surface of the yarn;
- and
- squeezing the yarns after sizing at a pressure between 15 KN and 21 KN, inclusive to keep the sizing chemicals at the surface of the yarn.
A method of producing a denim fabric from a low twist, combed, indigo yarn, the method comprising:
- weaving a denim fabric, wherein the weaving comprises:
- feeding the warp yarns in a loom through a front roller and a back roller;
- wherein the warps yarns are under less tension when a shed is open, and
- wherein an angle between the front roller and the back roller is between 1.8 and 2.8 degrees, inclusive,
- wherein the yarn comprises:
- a twist multiple between 2.0 and 3.4, inclusive;
- a sizing at the surface of the yarn;
- and
- a dyed core wherein an indigo dye penetrates deeply into the core,
- wherein the sizing remains substantially at the surface of the yarn.
A denim fabric comprising a low twist, combed, indigo yarn, said denim comprising:
- yarn having a twist multiple between 2.0 and 3.4, inclusive;
- a sizing at the surface of the yarn, and
- dyed yarn having a dyed yarn core wherein an indigo dye penetrates into the yarn core;
- and wherein the sizing is kept substantially at the surface of the yarn.
