Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cellulosic fiber-containing stretchable fabric which is excellent in texture, shrinkage resistance, stretchability, practical use in washing and the like, and excellent in wearing comfort.

[0002]

2. Description of the Related Art Cellulosic fibers have a soft texture and excellent water absorption and hygroscopicity, and are widely used mainly in garments such as fabrics and knits. However,
Since it has drawbacks such as easy wrinkling and shrinkage during washing, it has been conventionally improved by various methods.

[0003] Polyurethane fibers have excellent stretch performance at the yarn stage, and fiber products made using such characteristics have excellent fit when worn. It has been widely used. In recent years, utilizing the characteristics of polyurethane fiber, it is possible to move freely without feeling cramped when wearing it, and to use outer materials such as pants, slacks, shirt fabric etc. that is comfortable, slim and novel design Has also been developed.

[0004] However, while such excellent stretch performance can be exhibited, there is a demand for improved handling properties in actual use, such as easy shrinkage during washing and drying and wrinkling after wearing.

[0005]

SUMMARY OF THE INVENTION The present invention has been studied diligently in view of the above circumstances, and has excellent shrink resistance and stretchability, and can be used for outer garments such as pants, shirts, suits, and coats. An object of the present invention is to solve the above problem by obtaining a fabric suitable for an inner material and composed of a cellulosic fiber and a polyurethane fiber.

[0006]

That is, the present invention provides a fabric having a stretch property in at least one direction, comprising a cellulosic fiber and a polyurethane elastic yarn, wherein the dimensional change is from -3.0% to 3%, A stretchable fabric containing cellulosic fibers, characterized in that the stretchability in the direction of greater stretchability is 10% or more and the stretch recovery rate is 40% or more. And specifically, the cellulose-based fiber-containing stretchable fabric described above, which is made of a woven fabric, the cellulose-based fiber-containing stretchable fabric described above, which is obtained by performing a shrink-proofing process, and cellulose. The cellulose-based fiber-containing stretchable fabric according to the above, wherein the content of the base fiber is 20% or more, and the content of the polyurethane elastic yarn is 1% or more.

Hereinafter, the present invention will be described in detail.

[0008] The cellulosic fiber used in the present invention is:
Fibers composed of natural cellulose fibers such as cotton and hemp or cellulosic semi-synthetic fibers such as rayon, cupra, polynosic, lyocell and the like, and mixed products thereof.

The polyurethane elastic yarn is a synthetic fiber having a polymer skeleton containing a urethane bond and having a high stretch property, and the polymer skeleton may be any of a polyether type and a polyester type.

The term "fabric" includes a woven fabric, a knitted fabric and the like made using the above-mentioned cellulosic fiber and polyurethane fiber.

These fabrics include polyester, polyamide, acrylic, polyethylene, polypropylene,
Synthetic fibers such as polyketones, metal fibers such as steel fibers and glass fibers, and inorganic fibers for the purpose of imparting more special functions may be included.

The content of cellulosic fibers in these fabrics is preferably at least 20%, more preferably at least 30%.
That is all. If it is less than 20%, it is difficult to sufficiently exhibit the texture, water-absorbing and moisture-absorbing properties, which are the characteristics of the cellulosic fiber, and it is difficult to obtain the dimensional stability effect by shrink-proofing. When the content of the cellulosic fiber is 20% or more, a chemical shrinkage effect such as mercerization processing, liquid ammonia processing, bioprocessing, resin processing, and gas-phase formalin processing is easily imparted.

[0013] The fabric of the present invention has stretchability, and by such characteristics, it is possible to obtain the fit and comfort when worn, which is a characteristic of the fabric, and the stretch direction of the fabric is the longitudinal direction. , Or one of the horizontal directions, but the effect can be further clarified by using two directions.

For the purpose of obtaining these stretch properties, it is essential that the fabric of the present invention contains a polyurethane elastic yarn. Further, the content of the polyurethane elastic yarn must be 1% or more. If it is less than 1%, not only sufficient stretchability cannot be obtained, but also comfort during wearing cannot be obtained. More preferably, the content is 2% or more.

The elongation-recovery characteristic of the fabric of the present invention is measured by the following method. Elongation rate: JIS L1096 G method Elongation recovery rate: JIS L1096 B-1 method

The elongation of the fabric of the present invention is desirably 10% or more, and the elongation recovery is desirably 40% or more. If the elongation is less than 10%, sufficient stretchability cannot be obtained. On the other hand, if the elongation recovery rate is less than 40%, problems such as knee dropouts and cracks occur in actual use, which is not preferable. These problems are unlikely to occur if the fiber product has an elongation rate and an elongation recovery rate in one of the longitudinal direction and the lateral direction, and the elongation rate is preferably 13%.
As described above, the elongation recovery rate is 50% or more.

The dimensional change of the fabric of the present invention is measured by the following method. Dimensional change rate: JIS L1096G method

It is essential that the dimensional change rate of the fabric be −3.0% or more and 3.0% or less in both the vertical and horizontal directions, more preferably −2.0% or more and 2.0% or less. % Or less. Exceeding these ranges is problematic in practical use.

Further, the fabric of the present invention is preferably subjected to a shrink-proof treatment. Examples of the shrink-proof processing include physical processing methods such as tumbler processing, cam fitting processing, and calendar processing, and chemical processing methods such as mercerizing processing, liquid ammonia processing, bioprocessing, resin processing, and gas-phase formalin processing. May be used.

The fabric of the present invention is preferably a woven fabric. By using a woven fabric, stretchability and shrinkage can be easily controlled, and shrink-proofing can be easily applied, so that effects can be easily obtained.

As described above, the fabric obtained according to the present invention is excellent in texture, shrink resistance and stretchability, and is excellent in practical use performance such as washing and comfort during wearing.

Hereinafter, the present invention will be described with reference to Examples.
The present invention is not limited by these examples. The fiber mixing ratio in the present invention is obtained by the following method. Fiber mixing ratio: JIS L1030-2 method
