Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lining fabric for use in garments having a coarse density, and more particularly to a lining fabric in which fibers constituting a lining warp or a weft are prevented from jumping out onto the surface of a surface material. It is.

[0002]

2. Description of the Related Art Conventionally, a cutting edge of a lining in sewing is prevented from fraying of a thread or the like by applying an overlock sewing machine or overcasting. However, in recent years, the purpose of preventing fraying is to streamline the sewing process. It is sewn without applying any treatment.

[0003] For this reason, there is a problem in that, when worn, the warp or weft fibers constituting the lining fabric jump out onto the surface of the garment when worn, and the appearance quality is greatly impaired. This phenomenon occurs remarkably in lining fabrics using synthetic fiber multifilament yarns having relatively high strength.

As a countermeasure, a method of interlacing warp and weft yarns and a method of twisting yarns can be considered. In the former case, however, the fraying from the cut edge is suppressed to some extent, and the lining textile fiber is applied to the surface of the garment. To prevent
Strong confounding is required, and the number of pieces is required to be 50 pieces / m or more. As a result, confounded portions are conspicuous, irritability is generated, and the feeling is rough, and the smoothness is reduced. In the latter case, if the twisted synthetic multifilament yarn is used for both the warp and the weft, the blowing-out prevention effect can be obtained, but the number of twists is required to be 400 T / m or more. Sex will be worse. Therefore, in order to obtain the desired feeling and smoothness, it is necessary to reduce the weight of polyester by 10% or more, and it is unavoidable that the cost and productivity decrease due to twisting, weight reduction and the like are unavoidable. Hard to say.

[0005] Furthermore, a lining fabric in which both warp and weft yarns are interlaced and further twisted has been proposed (Japanese Patent Publication No. 6-60441), but this also applies to both interlacing and twisting. Cost,
Very disadvantageous in terms of productivity.

[0006]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, prevents the occurrence of blowing on the surface of the surface material, has no irritability, is excellent in feeling and smoothness, and is low in cost. It is an object of the present invention to provide a lining fabric excellent in productivity.

[0007]

The inventor of the present invention has conducted various studies to solve the above-mentioned problems. As a result, the present inventors have applied only twisting, which causes cost increase and productivity reduction, to only the warp yarn. The present inventors have found that the cover factor (CF) of the woven fabric may be selected within an appropriate range by using a low-entangled crimped multifilament yarn, and the present invention has been completed.

That is, the present invention provides a twist number of 400 to 800 T /
Non-crimped synthetic fiber multifilament yarn having a fineness of 50 to 100 De having a twist of m is used as a warp yarn, and a crimped synthetic fiber multifilament yarn having a fineness of 50 to 100 De having an entanglement of 5 to 30 yarns / m is used as a weft. The cover factor (CF) of the fabric represented by the following formula is 1300 × a ≦
CF ≦ 1900 × a (where a indicates a fabric texture coefficient,
1.0 for a flat structure and 1.35 for a twill structure.

[0009]

(Equation 2)

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The synthetic fiber multifilament yarn used in the present invention is a synthetic fiber multifilament yarn such as polyester or polyamide, and the total fineness of the multifilament yarn is 50 to 100 denier. If the total fineness is smaller than 50 denier or larger than 100 denier, the resulting woven fabric is not practically suitable for use as a backing.

Next, in the backing fabric of the present invention, 40
0 to 800 T / m, particularly preferably 600 to 800 T / m
A non-crimped synthetic fiber multifilament yarn having m twists is used. This twisting prevents the fibers from being opened and prevents the fibers from jumping to the surface of the fabric. 400T warp
If it is less than / T / m, the effect of preventing fiber opening is weak and the intended purpose cannot be achieved. If it exceeds 800 T / m, the feeling becomes rough and hard, the smoothness is reduced, and it is not suitable as a lining fabric. It is.

Further, in the lining fabric of the present invention, 5 to 5
A crimped synthetic fiber multifilament having 30 entangles / m is used. In such a crimped synthetic fiber multifilament yarn, due to slight entanglement and crimping, the fiber variation is appropriately suppressed, and the fiber is prevented from jumping out of the garment void.

The confounding of the crimped synthetic fiber filament yarn is usually performed by a fluid treatment using an interlace nozzle or the like. However, the present invention is not particularly limited thereto, and any known confounding means may be used. be able to.
The number of confounds must be 5 to 30 pieces / m, and 5 pieces / m
If it is less than 30%, a sufficient blow-out preventing effect cannot be obtained, and if it exceeds 30 pieces / m, the yarn will be constricted, and if it is a woven fabric, the smoothness will decrease and the texture will appear rough, and the irritability will occur. The appearance quality is greatly reduced. The value of the number of entanglements in the present invention is a value obtained by applying a weight of total denier × 0.2 g to a filament yarn sample having a length of 1 m and calculating the number of entangled portions by a hook drop method.

As the crimped synthetic fiber multifilament yarn, a synthetic fiber multifilament crimped by any known means can be used. In particular, a false twist crimped synthetic fiber multifilament yarn is used. Yarn is preferably used. The false twist crimping can be performed by any method such as a spindle type, an internal friction false twist type, and an external friction false twist type.

Further, the lining fabric of the present invention has a woven fabric cover factor (CF) of 1300 × a ≦ CF ≦ 1900.
It is necessary to satisfy the relationship of × a (where a indicates a fabric texture coefficient, which is 1.0 for a plain texture and 1.35 for a twill texture). Textile cover factor (C
When F) is less than 1300 × a, the binding force of the fabric structure is weak, it is difficult to prevent blowing, and there is a problem in the physical properties of the fabric. When it exceeds 1900 × a, the feeling becomes coarse and hard, Excessive weight reduction or the like is required to obtain a desired feeling, which leads to an increase in cost and a decrease in productivity, which is not appropriate.

The woven fabric cover factor (CF) in the present invention is determined by the following equation.

(1) Blowout ○: Not recognized. Δ: Slightly recognized. ×: Outstanding.

(2) Hand ○: Flexible and good. Δ: Somewhat coarse hardness. X: Strong coarse hardness.
