Description

[Detailed description of the invention] The invention relates to the construction of interlining for clothing.

BACKGROUND ART The application of nonwoven fabrics to interlining materials for clothing has been remarkable in recent years, and nonwoven interlining base materials having various properties are provided depending on the application. However, it is difficult to obtain an interlining material that provides 411 firmness, stiffness, 7 crans, shape retention, etc. to clothing without impairing the texture of the fabric. Recently, I have a fever
A soft and bulky nonwoven fabric base material obtained by heating and pressurizing a fiber web made of moldable synthetic fibers with an emboss roll engraved into an arbitrary shape is applied to interlining material. What is used is J[. but,
This type of interlining has a soft texture and is voluminous, but since no adhesive is used, it has drawbacks in terms of resilience and shape retention, and it is also resistant to washing and dry-freezing. The reality is that it is difficult to say that there is a

In view of these current circumstances, the present invention has developed a new clothing interlining material that takes advantage of the softness and bulkiness that are the advantages of conventional products, while also exhibiting excellent anti-flour elasticity, shape retention, and resistance to washing and dry cleaning. It provides:

That is, the present invention uses a fiber web mainly composed of thermoplastic synthetic #A fibers such as polyester, nylon, acrylic, vinylon, polypropylene, etc., such as acrylic or SBR.

On a base material obtained by impregnation or spray processing with a binder liquid whose main ingredient is a synthetic resin emulsion such as urethane or vinyl acetate, the above-mentioned polyester, nine, acrylic,
After layering the aita kuepkuue layer, which is mainly made of thermoplastic composite i*m such as vinyl resin and polypropylene, it is heated and pressurized with a pair of embossing rolls engraved into an arbitrary shape, and then the convex part of the embossing roll is applied. Only the laminated quench at the pressing tip portion is integrated into the melt layer, and the other unpressurized portions form bulky portions that are not fused. The temperature of the embossing roll at this time is preferably set to about 20 to 50 degrees Celsius lower than the melting point of the nine fibers used for web formation. At rh temperature, it becomes paper-like and hard; at lower temperatures, the heat-sealing and integration of the pressurized parts is insufficient, and it is difficult to obtain sufficient strength. In addition, when using a mixture of fibers from multiple types,
For example, polyester (melting point 250-260℃) and 6-6
Nylon (melting point 250℃), 6Ny (melting point 21
0~230''G) and vinylon (melting point 230~240
By combining materials with similar melting points, such as cI, it is possible to obtain interlining for clothing that has a good texture and a high resistance to scraping.

Furthermore, a thermoplastic binder such as polyamide, polyurethane, polyester, EVA, etc. is fixed in a substantially hemispherical dot shape to the l of the garment interlining obtained as described above, to which no binder is applied. After layering, we attempted to apply N-layering to a single strand of fabric used for clothing, and found that the texture after layering was extremely soft and bulky, with moderate stiffness and shape retention.
A very good interlining base material was obtained which had sufficient abrasion resistance to withstand washing and dry cleaning while also being durable.

An embodiment of the present invention will be described below according to the drawings. #2

This makes it possible to form an interlining.
