Abstract

PURPOSE: To obtain a heat-welding type interlining having anti-pilling properties against surface friction caused by laundry or the like, and durability by integrally carrying out embossing finish of an upper layer comprising a fiber web obtained by blending a thermoplastic anti-pilling fiber in a specific proportion, and a lower layer comprising a chemical fiber and a natural fiber. CONSTITUTION: This heat-welding type interlining for clothes, excellent in touch feeling and having durability against surface friction at the time of laundry, dry cleaning and wearing is obtained by integrally laminating an upper layer comprising a fiber web obtained by blending >=90 wt.% thermoplastic anti-pilling fiber having 2-3 g/d fiber strength (e.g. an anti-pilling polyester fiber) with a normal polyester fiber, with a lower layer comprising a fiber web obtained by using one or more kinds selected from chemical fibers natural fibers and the like, and applying an embossing finish to the laminated product under an embossing condition under which the anti-pilling fiber can be heat-welded. The interlining is also suitable for washable clothes.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention provides heat-sealable embossed clothing that is pill-resistant and durable against surface friction during washing, dry cleaning, or wearing. This relates to interlining.

[Conventional technology and its problems]

In recent years, there has been a rapid increase in clothing interlining from the conventional resin-impregnated type to the embossed fiber heat-sealed type due to its manufacturing cost advantages and texture. Wearing type interlining has the disadvantage that the strength between the embossed and fused fibers is weak, and the surface fibers tend to become fuzzed, pilling, and bubbling due to friction during washing, dry cleaning, or wearing. In order to prevent fuzzing, increasing the blending ratio of heat-fused fibers, or increasing the quality and pressure of embossing, the interlining becomes vapor-like, making it unsuitable for interlining with a hard texture. As a fused type interlining, there is a problem in using it for washable clothing which requires gfI resistance.

[Means for solving problems]

The present invention solves the above-mentioned drawbacks and provides a heat-sealable interlining for clothing that has an excellent texture and is resistant to fuzzing, pilling, and blistering. Next, the configuration of the present invention will be explained based on the drawings. Fig. 1 is a schematic cross-sectional view of the configuration showing one embodiment of the present invention.
The upper layer 1 contains at least 90% by weight of thermoplastic anti-pilling fibers (melting point = 236°C to 241°C) with a fiber strength of 2.0 to 3.0 g/d, and the remainder is polyester (melting point = 255°C). A cross web or random web with a basis weight of 10 to 20 g/i2 is used, which is made by blending synthetic fibers such as 6.6-nylon (melting point = 250°C to 260°C). As a thermoplastic polyester, 6.6-nylon, 6-nylon melting point:
(215°C to 220°C), acetate, rayon, seed hair fiber, etc., chemical fibers or natural fibers are blended singly or in combination with a basis weight of 5 to 80 g/m2, and the fiber arrangement is parallel, cross, random, or A fiber web made of a combination of these, for example, a laminated web composed of a cross web, is embossed with embossed call 3 as shown in FIG.
A pressing force of 3 is applied by a pair of rolls with a surface temperature of 200°C to 220°C and a flat roll 4 whose surface temperature is 190°C to 210°C.
0~60kg/c! 1 is heated and pressurized to heat-seal the parts, and a point-shaped heat-sealed part 6 is formed by applying pressure at the convex part 5 of the embossing roll 3. In addition, if the composition of anti-pilling i-co fiber in the upper layer is less than 90%,
Due to the influence of synthetic fibers (hereinafter referred to as regular fibers) that have strong fiber strength, when the fiber fusion part is peeled off due to friction, the fibers do not break unlike anti-pill fibers.
The fluff and its regular fibers become the core of the pill and cause fluff, and when the fluff expands, the fluff falls off due to the resistance of the fluff itself, and it no longer functions as an interlining. . Also, if the pJ fiber weight is less than 10 g/m2, the regular fibers blended in the lower layer will come out on the surface of the upper layer, causing fluff and pilling, and if it exceeds 20 g/m2, the interlining will have a hard texture. becomes. As for the fiber blend in the lower layer, the above-mentioned regular l'' fibers may be used in any blend, but if the blending ratio of fibers with a lower melting point than the anti-pilling fiber increases, the core will have a stiff texture. It is desirable to use it at a blending ratio of 5 to 50%. In addition, the PJ thread strength of the anti-pilling fiber is set to 2.0 to 3.0 g/d, and the force is lower than that of regular fiber (4.0 g/d or more), so that it does not pill when subjected to strong abrasion + U. This is because it needs to tear and fall off. In addition, as for the roll temperature during embossing, setting the embossing roll with which the upper layer is in contact to a higher temperature than the flat roll with which the lower layer is in contact will result in an interlining with excellent texture. The clothing interlining thus obtained may be used as is as a flage core, but the lower layer surface may be processed with temporary adhesion such as random powder or dot processing, or with adhesive resin 7 for permanent adhesion before use. It goes without saying that it is possible.

[Effect]

The clothing interlining obtained in this way has abrasion resistance because the thermoplastic anti-pilling fibers blended in the upper layer are thermally fused during surface friction during washing, dry cleaning, or wearing. It has excellent properties, and even if the embossed fused M fibers are peeled off, the regular fibers lf
Because the fiber strength is set lower than the t strength, the fibers are not cut, fluffing, pilling, or blistering occurs, and it can be used for washable clothing.

The present invention will be explained in more detail below with reference to Examples.
