DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastening material for clothing made of a stretchable nonwoven fabric. More specifically, a stretchable nonwoven fabric having a fiber having a loop-shaped crimp is treated with an adhesive. The present invention relates to a fastening material for clothing.

[0002]

2. Description of the Related Art Conventionally, tricot knits have been used as cuffs or hem openings applied to the sleeves or hem of clothing, and are joined to the inner or outer periphery of the sleeve or hem. Such a tricot knitted fabric, in order not to fray the cut surface,
A wrap is required. For this reason, the tip of the cuff or hem is folded inward, and the substantially U-shaped folded tip is overlapped with the tip of the sleeve or hem in a state of being approximately doubled, and the periphery thereof is sewn.

[0003]

The tricot knitted fabric is joined to the sleeve or hem of the garment as a cuff or a hem by sewing with a sewing machine or the like while applying tension to the tricot knitted fabric cut into a tubular shape. However, the tricot knitted fabric is too flexible, so that it is difficult to fold and handle it at the time of joining, it takes time and effort to process, and has a disadvantage of increasing the cost. Furthermore, when sewing a tricot knitted fabric with a sewing machine, a part of the tricot knitted fabric is cut with a sewing needle, so that there is a problem that a so-called run easily occurs. On the other hand, conventional stretchable nonwoven fabrics have a problem that they do not always adhere to the body after being worn because the recovery after stretching is not always sufficient.

[0004]

Means for Solving the Problems In order to solve the above-mentioned problems, the invention of the present application is to provide a stretchable sheet having loop-shaped crimped fibers at a fastening portion of clothing, particularly at a cuff or a hem, and an adhesive. And a stretchable nonwoven fabric having high elasticity and high recovery after elongation. The fastening material for clothing using the stretchable nonwoven fabric in which the stretchable sheet having the loop-shaped crimped fiber of the present invention has been treated with an adhesive is used for a fastening portion such as a sleeve, a hem, a collar or a hat, and gloves of clothing. It is preferable to use it.
Also, any clothing can be applied, but particularly suitable ones are, for example, disposable clothing such as surgical gowns, isolation gowns, surgical caps and shoe covers used in hospitals, and sterilization treatment with electron beam or γ-ray. It is more preferable that the material withstands.

As the stretchable nonwoven fabric of the present invention, for example, a web composed of latently crimpable short fibers is entangled with a needle punch or a water stream, and then a loop-shaped crimp is developed by heat treatment or the like. Those treated with an adhesive are preferred. In addition, a spunbonded nonwoven fabric by a composite spinning method or the like, a melt-blown nonwoven fabric, to express a loop-shaped crimp,
Those treated with an adhesive are also suitable. The nonwoven fabric can be used in a single layer, but can also be used in two or more layers, and by forming a multilayer, stronger elasticity can be obtained. Further, the nonwoven fabric preferably has flexibility and elasticity when stretched. As the fibers used for the nonwoven fabric, synthetic fibers are mainly used, but natural fibers, regenerated fibers, and the like may be mixed, and polyester fibers are more preferable in terms of sterilization treatment with electron beams, γ rays, and the like. Further, in consideration of perspiration during surgery, it is also preferable to use a mixture of moisture-absorbing and water-absorbing fibers such as rayon. Examples of the adhesive include natural rubber, synthetic rubber such as NBR and SBR, styrene-isoprene-styrene, styrene-butadiene-styrene, urethane-based elastomer, acrylic resin, ethylene-methyl acrylate, ethylene-vinyl acetate-based synthetic resin and the like. And a mixture thereof can be used, and those having elasticity are preferable. Further, as a method of treating with an adhesive, an impregnation method, a spray method, a coating method, a printing method, or the like can be used.

The elastic nonwoven fabric preferably has an elastic recovery rate of 70% or more in the transverse direction, that is, the circumferential direction, and more preferably 80% or more in the transverse direction, that is, the circumferential direction, as a fastening material. If it is less than 70%, the cuff or hem of the garment is easily stretched when a fist or the like is passed therethrough, and the feeling of wearing and the appearance are unfavorable. Further, the stress at 10% elongation is preferably 0.1 kgf / 5 cm or more, because the fit is excellent.

[0007] The fastening member and the fastening portion such as a sleeve, a hem or a hat can be joined by ordinary joining means such as sewing with a sewing machine, fusion with an ultrasonic wave or the like, and adhesion with an adhesive or the like. In the case of bonding, the stretchable nonwoven fabric may be impregnated or coated with a heat-sensitive or pressure-sensitive adhesive in advance, or may be bonded with another adhesive tape or the like.

[Measurement method] The elastic recovery after 70% elongation was determined by measuring a 5 cm wide test piece with a tensile tester in accordance with the elongation elastic modulus of JIS L 1096 (general textile test method).
Tensile speed 20cm / m from point Lo at gripping interval 10cm
from the point L ₂ (7 cm) which was pulled up to 70% of the grip interval by pulling in at in, when returning at the same speed, the length of the point L ₁ and the point Lo where the stress became zero is l ₁ (cm) age,
It was calculated by the following equation. The stress at the time of 10% elongation was measured according to the tensile strength and elongation measurement method of JIS L 1096 (general fabric test method) using a tensile tester to grip a test piece having a width of 5 cm with a gripping interval of 10 cm, a tensile speed of 20 cm / min, Is expressed as the stress at the time of 10% elongation when pulled. Next, examples will be described. The invention of this application is not limited to this.

The cuffs were 8 cm (for LL size) and sewn to the sleeves. The cuff thus obtained had a low elastic recovery rate after elongation when worn by a person with a wrist thickness of 20 cm, and had poor fit when worn. The elastic sheet not treated with the adhesive had an elastic recovery rate after elongation of 70% in the circumferential direction of 68.6% and a stress at the time of elongation of 10% of 0.07 kgf / 5 cm.

Example 3 A polyolefin-based spunbonded nonwoven fabric having latent crimping ability was heated to 135 ° C. to develop a loop-shaped crimp, and a stretchable sheet having a basis weight of 75 g / m ² was obtained. Further, the sheet is impregnated with a urethane-based binder and dried to obtain a basis weight of 9%.

[0014]

According to the present invention, since the stretchable nonwoven fabric having loop-shaped crimped fibers is treated with an adhesive, the stretchable nonwoven fabric having a loop-like crimped fiber is not used. On the contrary, since the stretch recovery property is good, the fitting property is good, and the occurrence of lint is small. Also, since the cut part does not fray like a tricot knit, it is easy to join the sleeves and cuffs or hem and hem mouth of clothing even with a sewing machine, ultrasonic wave, adhesive, etc. without folding even a single layer Can be. Compared to the conventional cuffs or hem, the processing step is simplified by the fact that the cut surface is not frayed, so that it is possible to provide a garment having cuffs or hem with excellent fit easily and inexpensively. This is particularly effective in disposable garments requiring low cost.
