BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interlining and an adhesive interlining using the interlining.

[0002]

2. Description of the Related Art Conventionally, as an interlining material, a non-woven fabric in which nylon fibers, polyester fibers or the like are partially thermocompression bonded, or a non-woven fabric entangled with a water stream has been known. However, these interlinings have no resilience, and clothes using this interlining are likely to lose their shape.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide an interlining material having excellent repulsion property and an adhesive interlining material using the interlining material. .

[0004]

The interlining of the present invention is obtained by a solvent extraction method with an apparent Young's modulus of 1,000 kg / mm ² or more.
It consists of a non-woven fabric containing lulose fiber,
The fibers are fibrillated, and the non-woven fabric is hydroentangled.
It ’s a more profitable one. This apparent Young's modulus is 1,000 kg / mm
Cellulose fiber obtained by ^more than one solvent extraction process is excellent in strength <br/>, since the nonwoven fabric is one obtained by hydroentanglement method, is excellent in feeling and repellency.

The adhesive interlining of the present invention is one in which an adhesive resin is attached to the above-mentioned interlining.

[0006]

The present invention has found that a nonwoven fabric containing fibers having an apparent Young's modulus of 1,000 kg / mm ² or more is excellent in resilience and is suitable as an interlining material.

As the fibers having an apparent Young's modulus of 1,000 kg / mm ² or more, for example, cellulose fibers obtained by a solvent extraction method, aromatic polyetheramide fibers, etc. can be used, but they are obtained by the former solvent extraction method. Cellulose fibers are
For example, it is sold under the trade name of Tencel by Courtles, and has excellent strength and is not colored, so that it can be suitably used.

The fibers having an apparent Young's modulus of 1,000 kg / mm ² or more are preferably contained in the nonwoven fabric in an amount of 20 to 90% by weight. If the content of fibers having an apparent Young's modulus of 1,000 kg / mm ² or more is less than 20% by weight, the repulsion property tends to be weak, and if it exceeds 90% by weight, the texture tends to deteriorate, and more preferably, It is 30 to 80% by weight.

As the fibers other than the fibers having the apparent Young's modulus of 1,000 kg / mm ² or more, for example, nylon 6, nylon 66, nylon 610, nylon 11, nylon 12 and copolymer nylon are used to impart flexibility. Or, a nylon fiber made of modified nylon or the like in which a compound containing a sulfone group is bonded to or copolymerized with a part of these nylons, or polyethylene terephthalate, polybutylene terephthalate, or these resin components for imparting dimensional stability. A polyester fiber made of a sulfonated aromatic dicarboxylic acid such as 5-sulfoxyisophthalic acid or the like, or a modified polyester copolymerized with this salt can be preferably used.

The fiber does not have to be a single component, for example, a core-sheath type in which the fiber cross-sectional shape is concentric or eccentric, a chrysanthemum type in which one component is divided by another component extending from the fiber axis, A laminated type in which two or more layers of a component and another component are bonded together,
You may use or use together the sea-island type | system | group which disperse | distributes one component in another component, and has a composite fiber which has characteristics, such as shrinkability, fusion property, or splittability.

The fineness of the fibers constituting the nonwoven fabric of the present invention is preferably 0.01 denier or more so as not to reduce the strength, and is preferably 3 denier or less so as not to impair the flexibility. More preferably, 0.05-2
It is denier. The fiber length is not particularly limited, but a fiber length of about 3 to 100 mm can be used.

The fiber web is formed from the fibers as described above. Examples of the method for forming the fiber web include a dry method and a wet method such as a card method and an air lay method. According to the former dry method, a relatively bulky and flexible fiber web can be formed, and according to the latter wet method, a dense and uniform fiber web can be obtained, which may be appropriately selected or combined.

When the fiber web is formed by the card method, the orientation direction of the fibers is set to the flow direction of the fiber web, or the fiber web is crossed with the cross direction by a cross layer or the like. It can be laminated. Among these, it is preferable to include a fibrous web that intersects the flow direction of the fibrous web, because an interlining having a small strength difference between the horizontal direction and the vertical direction can be obtained.

Further, fiber webs having different fiber configurations may be laminated, and in the present invention, the fiber web is formed by appropriately combining the fiber web forming method, the orientation direction of the fibers, and the fiber configuration of the fiber web. it can.

The basis weight of this fiber web is preferably 10 to 60 g / m ² . When it is less than 10 g / m ² , the fibrous web is significantly uneven and does not form a fibrous web. When it exceeds 60 g / m ² , the flexibility is lost.
50 g / m ² , most preferably 20-40 g / m ² .

Next, this fiber web is entangled, but in order to improve the handleability of the fiber web, entanglement treatment such as needle punching or water flow may be performed as a pretreatment. Examples of the bonding method of the fiber web include, for example, a method of bonding with a binder, a method of partially bonding by utilizing the thermoplasticity of the fiber web constituent fibers, a method of entanglement with a needle punch or a water stream, a method of stitching, Alternatively, there is a method of using these methods together. Among these, the method of entanglement by water flow is structurally flexible even if fibers having a high apparent Young's modulus are used, can impart repulsion without impairing the texture, and has a smooth surface. Since it is possible to obtain a non-woven fabric, this is a preferable bonding method.

The condition for the entanglement with the water flow may be, for example, a net or a perforated plate made of plastic or metal as a support for supporting the fibrous web. Inch plain weave net is suitable, and in the case of perforated plate, the distance between holes is 0.10 to 0.4.
Those having a diameter of 0 mm can be preferably used. As described below,
When the adhesive resin is adhered to the interlining material to form the adhesive interlining material, a plain weave net of 60 to 150 per inch or an inter-hole distance of 0.15 to 0.40 is provided so that the adhesive resin does not come off.
It is preferable to use a perforated plate of mm to have a smooth surface.
The nozzle for ejecting water preferably has a diameter of 0.05 to 0.3 mm and a pitch of 0.2 to 3.0 mm, a water ejection pressure of 20 to 300 kg / cm ² , and an ejection angle of 9 to the fiber web.
It is preferably 0 °. Furthermore, the number of treatments with a water stream is not particularly limited.

When a fiber web containing cellulose fibers obtained by a solvent extraction method as fibers having an apparent Young's modulus of 1,000 kg / mm ² or more is entangled with a water stream, the cellulose fibers are entangled and fibrillated at the same time. However, in order to make the front and back surfaces have the same resilience, the hydroentanglement conditions should be adjusted so that the front and back surfaces do not fibrillate, or even if fibrillated, the degree of fibrillation on the front and back surfaces should be about the same. Preferably.

The interlining is obtained as described above, but in order to improve the texture, silicone oil is added to the interlining of 0.2 to
About 10% by weight is preferably attached.

By attaching an adhesive resin to at least one surface of this interlining, the adhesive interlining having more versatility can be obtained. In addition, when bonding the adhesive interlining to the outer material, a resin that does not substantially melt at the temperature at which the adhesive interlining is bonded (hereinafter referred to as "non-melting resin") is attached to the interlining to prevent reverse stains. After this, the adhesive resin may be attached onto the non-melting resin.

As the adhesive resin, for example, polyethylene-based, polyamide-based, polyvinyl chloride-based, polyester-based resins and the like can be used. Among these, the polyamide-based adhesive resin has excellent adhesiveness to various surface materials. For,
It can be preferably used. On the other hand, as the non-melting resin, for example, a self-crosslinking acrylic ester resin, a crosslinkable polyurethane resin, a crosslinkable silicone resin, a crosslinkable nitrile rubber, and other synthetic resins and modified products thereof can be used. The cross-linked acrylic ester resin is excellent in flexibility and therefore can be preferably used.

Such an adhesive resin or non-melting resin can be applied, for example, after making it into a paste, using a screen or a gravure roll. It should be noted that, in order not to impair the adhesiveness and flexibility of the adhesive interlining by the adhered adhesive resin, the surface area of the interlining (the interlining surface is considered to be smooth) is 10 to 150 pieces / cm ² , resin Weight (including non-molten resin when having non-molten resin) is 4 to 4
It is preferably 0 g / m ² .

When non-molten resin is attached,
In synchronism with the screen or gravure roll to which the non-melting resin is attached, the adhesive resin is attached onto the non-melting resin,
After spraying the powdery adhesive resin on the non-molten resin, the excess adhesive resin is removed by mechanical means such as air or rod-shaped hits, and the adhesive resin is adhered only on the non-molten resin, This is a more preferable method for attaching the adhesive resin, since no extra adhesion occurs.

Examples of the present invention will be shown below, but the present invention is not limited to the following examples.
