Abstract

PURPOSE:To obtain a soft heavy-gage spun yarn woven fabric, excellent in drapeability and dryness, rich in voluminous feeling and having excellent tear strength. CONSTITUTION:The objective woven fabric is woven from warp yarn having (30/2) to (60/2) warp count (NT) (English cotton count), 4.5-5.5 warp yarn twist coefficient (K) and >=14.5 warp yarn cover factor (KT) and weft yarn having <=15.0 weft yarn cover factor (KW). In this wove fabric, the following formulas are satisfied: 2<=NW/NT<=3, 0.5:<=KW/KT<=0.9, KW=[{2n/2(NT)<2/1>}+-{SW /2(NW)<2/1>}]XWM/SW and KT=[{2n/2(NT)<2/1>}+{ST/2(NW)<2/1>}]XTM/SW [(n) is the number of interlaced points in one cycle; ST and SW are the numbers of warp and weft yarns in one cycle; NT is the English cotton count of the warp yarn; NW is the English cotton count of the weft yarn; WM and TM are densities (yarns/in) of weft and warp yarns]. The number of continuous floats of weft yarn in the complete weave of this woven fabric constructed therefrom is 2 to 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spun yarn fabric excellent in drape and dryness, and more particularly to a spun yarn fabric excellent in drape, soft and warm feeling.

[0002]

2. Description of the Related Art Conventionally, a heavy-weight woven fabric using twin yarns has almost the same count yarn for both warp and weft, and the difference in density between warp and weft is not so large. There wasn't. A woven fabric using filament yarn as a weft yarn is also produced, which is also adapted to the thickness of the spun yarn of the warp yarn.

[0003]

However, conventional heavy-weight woven fabrics using spun yarns for both warp and weft have poor drape and dryness, and lack softness and warmth. This is because there is a problem in the cloth quality such as slipping and tearing strength, and the thickness and density of each of the warp and weft must be the same. Therefore, the present invention provides a spun yarn fabric that is excellent in drape, dryness, softness, and warmth while using spun yarn for both warp and weft.

[0004]

The present invention adopts the following means in order to solve the above problems. That is, according to the present invention, in the spun yarn fabric, there is a relationship of the following formulas (1) to (4) between the weft yarn count NW, the warp yarn count NT, the weft cover factor KW, and the warp yarn cover factor KT. Count NT is 30/2 to 60/2'S Twist coefficient K is 4.5 to 5.5, cover factor KT is 14.5
As described above, the cover factor KW of the weft is 15.
A spun yarn woven fabric, which is 0 or less, and has a continuous float number of 2 to 4 in the complete design of the woven fabric. 2 ≦ NW / NT ≦ 3 (1), 0.5 ≦ KW / KT ≦ 0.9 (2) KW = [{2n / 2 (NT) ^1/2 } + {SW / 2 (NW) ^1/2 }] × WM / SW (3) KT = [{2n / 2 (NT) ^1/2 } + {ST / 2 (NW) ^1/2 }] × TM / SW (4) However, n ... 1 design point in circulation ST ... 1 number of warp threads in circulation SW ... 1 number of weft threads in circulation NT ... warp count (English cotton count) NW ... weft count ( English style cotton count) WM… weft density (book / in) TM… warp density (book / in)

The present invention will be described in detail below. In the present invention, the relation between the thickness of the warp yarn and the weft yarn, the relation of the cover factor, the continuous floating number of the weft yarn, and further the twist coefficient of the warp yarn are devised so that the drapeability, the dryness,
It is designed to satisfy both softness and warmth at the same time. First, the use of spun yarn is for giving a warm feeling, and the use of twin yarns of 30/2 to 60/2'S is for making a heavy woven fabric.
If it becomes smaller, it becomes difficult to drape, while the other 60
If it is larger than / 2, the warm feeling becomes poor, which is not preferable. The ratio NW between the weft yarn count NW and the warp yarn count NT
/ NT must be in the range of 2 ≦ NW / NT ≦ 3. When NW / NT is less than 2, it becomes hard and the drape property and the warm feeling are poor, which is not preferable. On the other hand,
When NW / NT is larger than 3, tear strength is lowered, which is not preferable. To improve the dryness of the fabric,
It is preferable that the twist coefficient K of the warp is about 4.5 to 5.5. If it is less than 4.5, excellent dryness cannot be obtained,
If it exceeds 5.5, the dry feeling is excellent, but the characteristics such as drape are deteriorated, which is not preferable.

Next, the ratio KW / KT of the cover factor KW of the weft and the cover factor KT of the warp is 0.5≤K.
It must be within the range of W / KT ≦ 0.9. When it is smaller than 0.5, the slip between the warp and the weft becomes large,
On the other hand, when it is larger than 0.9, it becomes hard and the drape property and the warm feeling are both deteriorated, which is not preferable. The cover factor KT of the warp is 14.5 or more, preferably 14.5 or more, preferably 14.5 to 17.5, and the cover factor KW of the weft is 15.0 or less, preferably 8 to 1
2.5, more preferably 10 to 12.5. If the cover factor KT of the warp is less than 14.5, the feeling of warmth becomes poor, which is not preferable. If the cover factor KW of the weft exceeds 15.0, it is not preferable in terms of drapeability. In order to exert the drape property better, the stress ST2 at 2% elongation is 0.4 g / d or less, preferably 0.3 g / d or less. This is considered to improve the drapeability in combination with the cover factor and the thread thickness.

Furthermore, the continuous float number of the weft threads in the complete design of the fabric must be 2-4. If the continuous float number is less than 2, it lacks in softness, and if it exceeds 4, slippage occurs, which is not preferable. The material of the spun yarn of the present invention includes 100% cotton, mixed spinning of cotton and polynosic fiber, 100% polynosic fiber, and the like, and 100% polynosic fiber is preferable in terms of drape.

In the present invention, when the plain weave is taken as an example, the design point n in one circulation is n = 1, the number of warp yarns ST and the number of weft yarns SW are both ST = SW = 2. /
In the case of 1, n = 1, ST = SW = 3, 2/2, 3 /
In the case of 1, n = 1 and ST = SW = 4, and in the case of satin, n = 1 and ST = SW = 5. The stress ST2 at 2% elongation is P / (L '× D / L)
It is expressed in (g / d). L is the test length (mm), L '
Is 2% elongation (mm), P is the load (g / d) at the maximum point of the cut line angle at 2% elongation, and D is the fineness (tex) of the sample.
Is.
