Description

[Detailed Description of the Invention] The present invention provides a fused interlining having excellent properties such as excellent hand feel and no resin seepage.

Previous attempts have been made to apply thermoplastic resin powder to tricot fabric and use it as an interlining material since 1973.
Shown in 32489.

However, products using such tricot fabrics are difficult to handle because the fabric itself is too soft and the peripheral portions curl, resulting in extremely unstable shapes.

Furthermore, when the thermoplastic resin powder is applied and bonded to the outer fabric using an iron or the like, the resin oozes out to the trichome fabric side, significantly inhibiting ironing slippage. In addition, in the case of coarse tricot fabric, the particle size must be made coarser to prevent the resin from falling between the loops, which not only deteriorates the texture but also causes it to seep into the outer fabric. .

In view of these drawbacks, the inventors of the present invention conducted various studies and were able to obtain a fused interlining having excellent properties.

To explain the present invention with reference to the drawings, the nonwoven fabric 2 of the base fabric 3 is formed by integrating a knitted fabric 1 and a nonwoven fabric 2 with the warp direction of the knitted fabric 1 and the arrangement direction of the fibers of the nonwoven fabric 2 substantially aligned. This is a fusion interlining characterized by having a heat fusion resin 4 applied thereon.

In the present invention, knits are knitted by looping yarn, and are divided into warp knitting, which is represented by tricot knitting, and weft knitting, which is represented by circular knitting, depending on the direction of the loops.

In the present invention, the nonwoven fabric generally refers to a web made of natural, synthetic, or semi-synthetic fibers with a fiber length of about 20 to 100 mm, or a blend thereof by a known web forming method such as carding or airlaying, or a web made of these webs. These fibers are obtained by adding an adhesive to bond the fibers, or these fibers are mixed with heat-fusible fibers in an amount of about 5 to 40% by weight, and heated after forming a web. These include those in which the fibers are bonded together, and so-called spunbond nonwoven fabrics obtained by melt spinning.

In order to integrate such knits and non-woven fabrics, the knits or non-woven fabrics are coated or impregnated with an adhesive solution, stacked together and then heated and dried, or powdered resin is sprinkled on them and then heated. Alternatively, the two may be entangled by needle punching or the like. Furthermore, when it contains heat-fusible fibers in advance,
They can be easily integrated by stacking them or entangling them with a needle punch or the like and then heating them. This nonwoven fabric does not necessarily have to be present on one side of the knit, but may be present on both sides. In addition, in this invention, the unidirectional nonwoven fabric, in which most of the constituent fibers of the nonwoven fabric are arranged in the longitudinal direction, is integrated with the warp direction of the knit approximately aligned, so it has extremely high elasticity in the width direction. Since it is easy to obtain, it becomes an extremely preferable fusion interlining for laminating with stretchable outer materials such as knitwear.

A heat-fusible resin is applied onto the base nonwoven fabric obtained in this way, but the heat-fusible resin melts when heated to approximately 100 to 150 degrees Celsius using an iron or a press, and adheres to the fabric. Various synthetic resins such as polyamide resins, polyester resins, and polyethylene resins are mainly used.

If this heat-fusible resin is in powder form, it can be sprinkled, or if it is in paste form, it can be applied in dots.
If it is in the form of melt-spun fibers, it can be applied continuously or discontinuously to the nonwoven fabric by placing it directly or indirectly.

As described above, in the present invention, by applying a heat-fusible resin to a nonwoven fabric, an excellent fused interlining with good tension and elasticity, excellent texture, and no resin seepage can be obtained. It is.

If heat-fusible resin is applied to the knit, the heat-fusible resin will adhere to the intersections of the loops that make up the knit, so when it is bonded to the outer material, the knit will lose its flexibility and the texture will be extremely poor. It becomes hard, and if heat-fusible resin is applied to coarse knit, fine particles or dots will fall into the gaps between the loops of the knit, so there will be less material that contributes to adhesion to the outer fabric. Therefore, a large amount of heat-fusible resin is required, or it is necessary to use a material with a large particle size or dot size. As a result, the texture is significantly impaired and resin seeps into the outer material.

In the present invention, by applying a heat-fusible resin on the nonwoven fabric of the integrated base fabric, the heat-fusible resin is retained on the approximate surface layer of the nonwoven fabric, so fine particle size or dot size heat-fusible resin is applied. A small amount of adhesive resin provides a sufficient adhesive effect, and it is not affected by the roughness of the knit. Therefore, even if this is bonded to a thin outer fabric, a very useful fused interlining with firmness can be obtained without the resin seeping into the outer fabric.

The present invention will be explained below with reference to examples.

Example 1 A nonwoven fabric of 15 g/m ² polyester fiber web is layered on 18 g/m ² nylon tricot fabric (15 denier half), impregnated with acrylic adhesive solution, dried, and heat treated to produce 50 g/m ² A base fabric was obtained. A heat-fusible polyamide resin was applied in dots at 18 g/m ² onto this non-woven base fabric to obtain a fusible interlining. This fusion interlining had tension and elasticity, and when used for the collar and cuffs of a knitted shirt, the resin did not seep into the outer material, had tension and elasticity, and did not cause elasticity.

Example 2 A unidirectional web nonwoven fabric made of 8 g/m ² polyester fibers was layered on a 18 g/m ² nylon tricot fabric (15 denier half) with matching directionality, and coated with an acrylic adhesive solution. After impregnation, a base fabric of 28 g/m ² was obtained by drying and heat treatment. A heat-fusible polyester resin was applied in the form of dots at 15 g/m ² onto the nonwoven base fabric to obtain a fusible interlining. This fused interlining had better shape stability and was easier to handle than a fused interlining whose base fabric was only a tricot fabric, and the cut edges did not fray at all, so it was extremely easy to work with in cutting, gluing, etc. Furthermore, even when bonded to the outer material, the texture was soft and firm, and there was no resin seeping into the outer material.

In addition, a unidirectional web made of polyester fibers was impregnated with an acrylic adhesive solution, dried, and heat-treated to obtain a 36 g/ ^m2 nonwoven fabric, and a similar heat-fusible polyester resin was applied in dots at 15 g/m2. ^m2
Comparing this fused interlining with that applied, this fused interlining was far superior not only in feel, but also in surface durability after washing or dry cleaning, and in terms of shape stability of buttonholes. As described above, the fused interlining of the present invention is superior in that it overcomes the drawbacks of fused interlining made only of nonwoven fabric.
