Abstract
A textile with high weave density which comprises a main-yarn made of a Japanese paper yarn and a sub-yarn thinner than the main-yarn interwoven with each other, wherein the textile has a weave texture structure including warps A and wefts A made of the main-yarn, and warps B and wefts B made of the sub-yarn, wherein in the weave texture structure, warp rows have a repeating row structure where a plurality of warps B are located between two warps A and weft rows have a repeating row structure where a plurality of wefts B are located between two wefts A, and wherein the warps A and the wefts A cross each other in a plain weave texture structure.
Claims18
A textile comprising:
- a main-yarn;
- and
- a sub-yarn,
- the main-yarn and the sub-yarn being interwoven with each other,
- the main-yarn being a yarn including 50% by weight or more of Japanese paper which is slit into a tape shape, the Japanese paper being made from a paper material including 90% or more of fibers obtained from at least one of paper mulberry, oriental paper bush, hemp, conifer, and bamboo grass, and the Japanese paper having a weight per unit area in a range of 10 to 20 g/m2,
- the sub-yarn being a yarn made of natural fiber for spinning and weaving, or made of artificial fiber, the sub-yarn having a weight per unit length that is 1/7 to ⅔ of the weight per unit length of the main-yarn,
- the textile having a weave texture structure including a warp A made of the main-yarn, a weft A made of the main-yarn, a warp B made of the sub-yarn, and a weft B made of the sub-yarn,
- in the weave texture structure, warp rows having a repeating row structure where one or two warps B are located between two warps A, weft rows having a repeating row structure where one or two wefts B are located between two wefts A, and
- the warp A and the weft A crossing each other in one of a plain weave texture structure and a twill weave texture structure in the texture,
- the textile having a weave density coefficient of 8.5 to 14, the weave density coefficient being defined as K=W×√G, with W being a value defined as W=(W1+W2)/2, where W1 represents a warp density of the textile and W2 represents a weft density of the textile, and G being a value defined as (4×G1+G2×(m+n))/(4+m+n), where G1 represents a linear density of the main-yarn, G2 represents a linear density of the sub-yarn, m represents a number of warps made of the sub-yarn located between two warps of the main-yarn, and n represents a number of wefts made of the sub-yarn located between two wefts of the main-yarn, and
- the textile having a value of t/P of 1/15 to ¼ where P represents a product of the number of warps and the number of wefts, the warps and the wefts being present in a unit area of the textile, and t represents the number of floats in which the number of skipped yarns by the main-yarn is 3 to 4, the floats being present on one side of the unit area.
