Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to an embossed heat-sealable interlining for clothing that is pill-resistant and durable against surface friction during washing, dry cleaning, or wearing. . [Prior art and its problems] In recent years, in view of the advantages of manufacturing cost and texture, there has been a shift from the conventional resin-impregnated type to the embossed fiber heat-sealed type of interlining for clothing. However, the strength between the embossed and fused fibers in heat-fused interlining is weak, and friction during washing, dry cleaning, or wearing can cause the surface fibers to become fuzzed, causing pilling and pooping. In addition, in order to prevent fuzzing, increasing the blending ratio of heat-fused fibers, or increasing the embossing temperature and pressure, the interlining becomes paper-like and has a hard texture. Because it is unsuitable for use as a heat-sealable interlining, it is problematic to use it in washable clothing that requires abrasion resistance. [Means for Solving the Problems] The present invention solves the above-mentioned drawbacks by providing a heat-sealable interlining for clothing that has an excellent texture and is resistant to fuzzing, pilling, and blistering. This solves the above problems. Next, the configuration of the present invention will be explained based on the drawings. FIG. 1 is a schematic cross-sectional view showing one embodiment of the present invention, in which thermoplastic anti-pilling fibers (melting point: 236°C to 241°C) with a fiber strength of 2.0 to 3.0 g/d are used as the upper layer 1 at a temperature of at least 90°C. % by weight, the remainder being polyester (melting point: 255℃~260℃)
A cross web or random web with a basis weight of 10 to 20 g/m ² is used, which is made by blending synthetic fibers such as 6.6-nylon (melting point: 250° C. to 260° C.). The lower layer 2 is made of thermoplastic polyester, 6.6-
Nylon, 6-nylon (melting point: 215℃~220℃),
Fibers with a basis weight of 5 to 80 g/ ^m2 , made by blending single or multiple types of chemical fibers or natural fibers such as acetate, rayon, and seed wool fibers, and whose fiber arrangement is parallel, cross, random, or a combination thereof. The web is, for example, a laminated web composed of a cross web, and as shown in Fig. 2, the surface temperature of the embossing roll 3 is 200°C to 220°C, and the surface temperature of the flat roll 4 is 190°C to 210°C, and the pressure is applied by a pair of rolls. Heat and pressure are applied at 30 to 60 Kg/cm to heat-seal the material and form point-shaped heat-sealed portions 6 by applying pressure at the convex portions 5 of the embossing roll 3. In addition, the composition of anti-pilling fiber in the upper layer is 90%
%, due to the influence of synthetic fibers with strong fiber strength (hereinafter referred to as regular fibers),
If the fiber fusion part is peeled off due to friction, the fibers will not be cut like anti-pill fibers, and the pill and fluff will be caused by fluffing and regular fibers, and if the pill expands. Due to the resistance of the fluff itself, the fluff falls off and no longer functions as an interlining. Also, if the fiber weight is less than 10g/ ^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 20g/ ^m2 , the core will have a hard texture. Become the earth. The regular fibers mentioned above may be used in any combination as the fiber blend in the lower layer, but if the blending ratio of fibers with a lower melting point than the anti-pilling fiber increases, the interlining will have a stiff texture. Therefore, it is desirable to use it at a blending ratio of 5 to 50%.
In addition, the fiber strength of the anti-pill fiber is 2.0 to 3.0 g/d, which is the strength of regular fiber (4.0 g/d or more).
This is because it needs to be made weaker than before, so that it will tear and fall off without pilling when it is subjected to strong friction. 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 material obtained in this way may be used as a plush interlining as it is, but
Needless to say, the surface of the lower layer can be subjected to temporary adhesion such as random powder or dot processing, or permanent adhesion using the adhesive resin 7. [Function] The interlining for clothing obtained in this way has thermoplastic anti-pilling fibers blended in the upper layer that are thermally fused during surface friction during washing, dry cleaning, or wearing. , has excellent abrasion resistance, and even if the embossed fused fibers are separated, the fiber strength is set lower than that of the regular fibers, so the fibers are cut and fluffing occurs, causing pilling and peach. It can also be used for washable clothing. The present invention will be explained in more detail below with reference to Examples. Example 1 Anti-pilling polyester fiber 1.5d x 51 as upper layer
A cross web with a basis weight of 10 g/m ² was formed using a cross wrapper machine using a mixed fiber of 95% mm (product name 775: Unitika Co., Ltd.) and 5% polyester fiber (2d x 51 mm), and the lower layer was 6-nylon fiber. 1.5d×51
mm, 20% and polyester fiber 2d x 51mm, 80% mixed fiber using the same cross-slapper machine.
After forming a cross web of 20 g/m ² and laminating it together through a lamination process, it is passed through a pair of embossing rolls set at an embossing roll temperature of 210°C and a flat roll temperature of 200°C, and heated at a pressure of 40 kg/cm. Pressure was applied to obtain interlining A with a basis weight of 30 g/m ² in which a fused portion was formed at the protrusion of the embossing roll. Example 2 Anti-pilling fiber used in Example 1 as upper layer
Fabric weight formed in the same manner as in Example 1 using a mixed fiber of 90% polyester fiber, 2d x 51 mm, and 10% polyester fiber.
Using a cross web of 10 g/m ² , a laminated fiber web was formed for the lower layer by forming a fiber blended web in the same manner as in Example 1, and using the same embossing conditions as in Example 1, a core with a basis weight of 30 g/m ² was formed. Got Earth B. Comparative Example 1 A cross web with a basis weight of 30 g/m ² was formed using a cross wrapper machine using a mixed fiber of polyester fiber 2d x 51 mm, 80% and 6-nylon fiber 1.5 d x 51 mm, 20%, and the embossing conditions were the same as in Example 1. Interlining C
I got it. Comparative Example 2 A cross web formed with the same fiber composition as Comparative Example 1 was heated at an embossing roll temperature of 220°C and a flat roll temperature.
Processed at 210℃ with a pressure of 45Kg/cm and has a basis weight of 30g/cm.
An interlining D of m ² was obtained. Next, the four types of interlinings obtained in each example and comparative example were subjected to paste dot processing of polyamide resin to obtain interlinings with 10 g/m ² of adhesive resin attached.
Fabric (furano:
100% wool) and bonded to interlining products A, B,
I got C and D. Next, we measured the texture of each interlining-laminated product, layered each interlining-laminated product (30 cm x 30 cm) and lining (100% polyester), overlocked the periphery, and tested the abrasion resistance by washing. Results first
Shown in the table.

[Table] As is clear from the above table, as a result of the test, products A and B of the present invention have better texture than comparative examples C and D, have good washing resistance, and have no pilling, making them ideal cores. The land was obtained. [Effects of the Invention] As described above, the present invention is a heat-sealable interlining for clothing that has excellent texture and is durable against surface friction during washing, dry cleaning, or wearing. It has excellent effects such as being suitable as an interlining for clothing that can also be used for washable clothing.
