Description

DETAILED DESCRIPTION OF THE INVENTION Fields of Application The present invention relates to conventional technology relating to non-woven interlining suitable for interlining of clothing such as men's clothing and women's clothing using wool (wool > -r, n). Conventional clothing such as men's wear and women's wear that uses a mixed nonwoven interlining has a problem in that the wool of the interlining protrudes to the surface of the outer material when worn or during dry cleaning, which significantly impairs the aesthetic appearance.

This problem can be solved to some extent by using preshrunk wool, but it is not enough, and especially in black clothing such as formal wear, it is difficult to avoid wool protruding from the interlining to the outer material. Therefore, complete prevention is required.

Problems to be Solved by the Invention The present invention has been made in response to such demands and to provide a nonwoven interlining that can substantially completely prevent wool from protruding from the wool-containing nonwoven interlining to the surface of the outer material. It is.

Means for solving the problem, that is, the present invention relates to a nonwoven interlining containing 1% or more of lO weight of wool that has been subjected to shrink-proofing and crimping.

The wool used in the present invention is made from the hair of cows, mohair, lamb, Angora goat, camel, albaca, or kanomiya, and is subjected to known shrink-proofing and crimping processes.

The length of the raw material is usually about 25 to 400 mm, especially about 25 to 76 mm, especially about 30 to 50 mm.

The shrink-proofing of wool may be carried out, for example, by a resin processing method or a chemical processing method. In the case of using the former, sufficient consideration must be given to the degree of processing, as the more complete the pre-shrinking, the more the properties of the wool will deteriorate and the physical properties will differ from those of the wool material of clothing. The material is treated with the same resin as the wool material. On the other hand, the latter processing method is preferable in the present invention, and in particular, the method described in JP-A-58-144105 can completely remove scale without changing the wool's properties such as strength and hygroscopicity. suitable.

Crimp processing can be carried out by any conventional method and is not particularly limited, but for example, wool that has been preshrunk treated as described above is soaked in a processing solution containing a reducing agent, stretched, and then pressed and steamed. This is done by steaming and setting.

Crimp processing is typically 4 to 4 inches per inch of wool.
If the processing degree is too small, the intended purpose of the present invention cannot be achieved, and on the other hand, if the processing degree is too large, it is currently difficult to perform crimp processing.

By performing this crimping process, wool is effectively intertwined with other mixed fibers, such as polyester and nylon fibers, and the separation of wool from the nonwoven interlining is effectively suppressed, so that wool is removed from the surface of the outer material. Protrusion is virtually completely prevented.

The content of the above-mentioned shrink-proofed and crimped wool in the nonwoven fabric is 10% by weight or more. If the wool content is less than 0% by weight, not only will it not be possible to take advantage of the soft and stiff texture that is characteristic of using wool-containing nonwoven interlining, but also the bonded part of the interlining will not be bonded. It is not possible to effectively prevent the so-called waving phenomenon that occurs in the boundary area between the two parts. In addition, the higher the wool content, the more the properties of the nonwoven interlining will approximate those of the clothing material, which is preferable, but the strength of the nonwoven will decrease, so it is important to consider It may be selected as appropriate depending on the type.

For example, when manufactured by the dip bonding method, the wool-containing TN layer is usually 10 to 100% by weight, preferably 10 to 95% by weight.
However, in the case of manufacturing by a heat fusion method, the amount is about 10 to 50% by weight.

In the dip bonding method, a web is prepared by a conventional method from a mixed fiber containing the above-treated wool and synthetic fibers such as rayon, vinylon, nylon, polyester, or acrylic fibers in a predetermined ratio, and the web is soaked in a resin solution. ,
For example, after being immersed in a resin liquid such as acrylic resin or SBR resin, it is dried and then cured. In this case, the resin adhesion 1 is 20 to 20 of the nonwoven fabric gold ball 1 in terms of solid content.
It is appropriate to set it at 50%.

In the heat fusion method, a web is prepared by a conventional method from wool that has undergone the above processing treatment and mixed Ik fibers containing thermoplastic fibers such as nylon, polyester or acrylic fibers in a predetermined ratio. The thermoplastic fibers are locally fused by heating with a heated embossing roll.

The type and blending ratio of the thermoplastic m-fiber to be mixed with the above-treated wool are appropriately selected depending on the properties required for the nonwoven interlining, such as flexibility, conformability, heat resistance, etc. do it.

Although the length and thickness of such thermoplastic fibers are not particularly limited, the length is usually about 25 to 76 mm.

Preferably it is 38 to 51 am, and the thickness is usually about 6 denier or less, preferably 3 denier or less, especially 1 to 3 denier.

If desired, as shown in the schematic cross-sectional view of FIG.
A nonwoven fabric interlining (1') containing the above is provided with heat-fused fibers f (IN (2)) such as nylon fibers on one side, and an adhesive (3) is attached to the fiber layer (2) to produce an interlining. However, by adhering this to the back side of the outer material, protrusion of the interlining wool onto the surface of the outer material can be more reliably prevented.

Such a non-woven composite interlining can be produced, for example, by stacking a layer of heat-fusible fibers, such as nylon or polyester, on one side of the non-woven interlining produced by the above-mentioned dip bonding method, and then subjecting it to a heat-fusion process. can get.

The nonwoven interlining according to the present invention may be used as a nonwoven adhesive interlining by applying an adhesive, such as polyamide, polyester, polyethylene, ethylene vinyl acetate, polyvinyl chloride, etc., in dots to one side of the nonwoven interlining. In this case, the number of adhesive dots is usually 18 to I907cra',
The coating amount is about 7 to 15 g/+e'', but is not limited to this [generally, fibers, adhesive (solid content) = 80:
20-50:50].

Hereinafter, the present invention will be explained by examples.

Example 1 Preshrunk and crimped wool 30% by weight and nylon (fiber diameter: 2 denier, fiber length + 32 mII)
) 70% by weight was prepared through a cotton blending process and a carding process (basis weight +3Qy/@'') was guided between an embossed metal roll and a flat metal roll,
A nonwoven fabric was produced by heat-sealing the fabric under conditions of 70 kg/Cf1l' at °C.

In order to prevent the wool from scattering, 3 to 5 g/i' of acrylic resin is applied to this nonwoven fabric by dipping, and a polyamide thermoplastic adhesive is applied to one side of the nonwoven fabric in irregular dots to form an adhesive core. (Number of adhesive dots: 112/square inch, adhesive coverage: IOg)
, /+').

This adhesive interlining had the movement of special wool and a soft, firm texture.

Even when the test cloth, which was sewn with this adhesive interlining sandwiched between wool outer fabrics, was subjected to dry cleaning treatment 10 times, substantially no protrusion of the wool onto the outer fabric surface was observed.

Example 2 Preshrunk and crimped 50% wool and nylon (fiber diameter, 2 denier, fiber length: 32 ma+
) 50% by weight was prepared through a cotton blending process and a carding process (wetness: I 38/m"), and 2~3g/11! of acrylic resin was soaked in the base fabric.
% web (fiber diameter -2 denier, fiber length: 32+nm,
Fabric weight: 13 geI11') was superimposed and heat-sealed under the same conditions as in Example I to produce a two-layer nonwoven fabric.

An adhesive interlining was produced by applying a polyamide thermoplastic adhesive in dots to the 100% nylon layer side of the nonwoven fabric in the same manner as in Example 1.

When a test cloth made by sewing this adhesive interlining between wool outer fabrics was subjected to dry cleaning treatment 10 times, no protrusion of the wool onto the outer fabric surface was observed.

Example 3 The nonwoven fabric interlining obtained in Example 1 or 2 was adhered to thin gabardine, and this was subjected to dry cleaning treatment 10 times. Substantially no protrusion of the interlining wool was observed.

In particular, in the case of the composite interlining obtained in Example 2, no protrusion of wool was observed at all.

Effects of the Invention By using the non-woven interlining according to the present invention, the protrusion of the wool of the interlining onto the surface of the outer material, which has been a problem in men's wear, women's wear, and other clothing that conventionally used wool-containing non-woven interlining, can be avoided. , the effect of the preshrunk treatment and the effect of the crimping treatment of the interlining wool are substantially completely prevented.
