Benefits of technology

[0014] An object of the present invention is to provide a flat multifilament yarn woven fabric exhibiting a hand with a high softness, a high water and perspiration-absorbing property, abrasion resistance, appropriate air permeability, light transmission and a high see through-preventing property.
[0015] Another object of the present invention is to provide a flat multifilament yarn woven fabric useful for constituting textile materials having an appropriate air permeability, textile materials having a high vision through-preventing property, textile materials having a high water and perspiration-absorbing property and / or textile materials having a high abrasion resistance.

Problems solved by technology

However, the high density woven fabrics, surface-coated and calendered woven fabrics usually have a low softness (a hard hand), and the surfaces of the fabrics exhibit a low resistance to abrasion (abrasion resistance, and thus these types of woven fabrics must be improved.
Thus, when the high transparency synthetic fibers are formed into a fabric and the fabric is used as an upper garment a problem such that a garment worn under the upper garment, namely an undergarment, can be seen occurs.
This increase in the weave density causes a problem that the resultant woven fabric exhibits a decreased softness.
However, usually, those properties are incompatible with each other and thus are extremely difficult to realize together.
However, generally speaking, the thick drape curtain has an excellent vision through-prevention and a poor light-transmitting property, and the thin lace curtain has an insufficient vision through-preventing property not only in nighttime but also in daytime.
The above-mentioned light-blocking fabric having a black-colored light-blocking layer formed on a fabric surface and light-blocking curtain have a problem that as the light-transmitting property is poor, the inside of the curtained room is dark and an oppressive atmosphere is created in the curtained room.
However, the mirror curtain has a problem that the vision through-preventing property of the mirror curtain, particularly in might time, is insufficient, and the sheeting gloss yarns cause a garish gloss, on the mirror curtain, to be created.
Further, the woven fabric made from synthetic fibers is disadvantageous in that the water-absorbing properties, especially perspiration-absorbing property of the synthetic fiber woven fabric is poorer than that of the woven fabric made from natural fibers, for example, cotton fibers.

Abstract

A flat multifilament yarn woven fabric having a low air permeability and excellent vision through-preventing property and water- or perspiration-absorbing property includes, as warp and / or weft yarns, multifilament yarns formed from a plurality of artificial individual filaments having a flat cross-sectional profile in which, on both the sides of a longitudinal center line of the profile, 3 or more projections projecting outward from the longitudinal center line and 2 or more constrictions formed between the projections, per side of the profile are formed approximately in symmetry with respect to the longitudinal center line, and a degree of flatness of the profile represented by a ratio (B / C1) of a largest length B of the profile in the direction of the longitudinal center line to a largest width C1 of the profile in the direction of right angles to the longitudinal center line is 2 to 6, the woven fabric having a cover factor of 800 to 3500.

Description

TECHNICAL FIELD [0001] The present invention relates to a flat multifilament yarn woven fabric. More particularly, the present invention relates to a woven fabric comprising multifilament yarns constituted from a plurality of artificial individual filaments having a flat cross-sectional profile with two or more constrictions per side section, and exhibiting a soft hand, a practically high water absorption, abrasion resistance and vision through-prevention. BACKGROUND ART [0002] Currently, various types of poorly air-permeable woven fabrics are provided for sport cloths and uniform cloths. As the low air-permeability woven fabrics, high density woven fabrics formed from synthetic fibers, for example, polyester or polyamide fibers, and coated woven fabric in which a resin coating layer is formed on a woven fabric, and calendered woven fabrics, are known. [0003] However, the high density woven fabrics, surface-coated and calendered woven fabrics usually have a low softness (a hard hand...
