Description

[Detailed description of the invention] This invention relates to a method for manufacturing sewn products.

Conventionally, men's clothing has generally been produced by thermally bonding an interlining or lining coated with an adhesive made of thermoplastic resin to an outer fabric, and then sewing the interlining or lining to the outer fabric. Although these men's clothing have the advantage of simplifying the sewing process, they have the disadvantage that the entire surface of the interlining or lining is bonded to the outer material with high peel strength, resulting in a hard texture. Therefore, men's clothing manufactured using the above method was sold at a low price and was treated as a low-grade product.

On the other hand, after twisting the interlining or partially tying the lining to the outer material with thread, and sewing the interlining or lining to the outer material,
There is a known method for manufacturing high-quality men's clothing in which the basting threads are removed to separate the interlining or lining from the outer material, but this manufacturing process involves many steps and requires considerable skill. There was a problem that manufacturing costs were high.

Laminate a polyvinyl acetal film that is heat-softening and easily soluble in cold water on one side of the interlining, or ′=! A polyvinyl acetal resin layer is provided by spraying the resin powder moistened with water or water, and the polyvinyl acetal resin layer is applied to the entire outer surface of the interlining and thermally bonded through the resin layer, and then the periphery of the adhesive piece is sewn with a sewing machine. After that, the resin layer was removed by washing with water, and the interlining and outer material were separated (Utility Model Act 1976-26).
585 Publication), but since the above-mentioned known method removes the polyvinyl acetal resin layer by washing with water θ), the above-mentioned known method can be applied to men's clothing, etc. When applied to sewn products such as bodies, washing with water causes the wool-containing outer material and interlining to shrink, resulting in a hard texture.

As a result of intensive research in order to solve the above problems, the present inventor invented a method for manufacturing a product with a simple manufacturing process and a texture similar to that of conventional high-class men's clothing. It has come to this.

Specifically, in the production of a sewn product in which at least one of the outer material, interlining material, and lining material is mainly made of wool, a thermoplastic resin layer is provided on the interlining material or the lining material, and the interlining material or the lining material is applied to the back surface of the outer material. The above heat iTJ plastic resin layer is bonded via the thermoplastic resin layer, and then the thermoplastic resin layer is dissolved and removed using a commercially available organic solvent to remove the interlining or lining material from the outer material. This is a manufacturing method for a sewn product σ) characterized by a cylindrical part k that is separated from Iyf.

The sewn product to which this invention is applied includes at least one of the outer material, the interlining material, and the lining material being mainly wool;
00% wool fabric, or wool fabric mixed with at most 20% of other fibers such as cotton, rayon, and synthetic fibers. To give a specific example, the outer material is 100%
The wool, interlining and lining are made of fibers other than wool, or the outer material is made of polyester, nylon, acrylonitrile, etc., and the interlining or lining is made of 100% wool.

The thermoplastic resin provided in the interlining or lining (hereinafter referred to as interlining etc.) has thermal adhesive properties, and preferred examples include polyamide-based, polyethylene/vinyl acetate-based, and polyvinyl chloride-based.

To provide the above-mentioned thermoplastic resin layer on interlining, etc., it is possible to spread resin powder, cast a resin melt, apply a resin solution dissolved in an organic solvent, or entangle it in a spider web shape. Any method can be used, such as thermally bonding a grooved non-woven resin. These thermoplastic resin layers may be provided uniformly on the entire surface of the cut interlining, etc., in the form of a box or dots, but as long as the workability during sewing is not hindered, the thermoplastic resin layer may be applied to the interlining as appropriate. It may be provided at a certain location (σ). The amount of resin solids applied when attached to interlining etc. is in the range of 5 to 30, preferably 5 to 20 (σ).

The above thermo-nT plastic resin is cut into a desired shape (・1
The interlining, etc., is placed on the back side of the outer material which has been cut into a shape, and then glued with a hosoto breath or adhesive. Next, in step Q), the peripheral edges of the folded fabrics are sewn together using a sewing machine, but since the outer material and interlining are glued and fixed as described above,
When sewing, the interlining etc. will not be in the same position, and the desired old shape 1
It is sutured with f]. 1. For the sewn product after 1 stitch. By impregnating the plastic resin with an organic solvent soluble therein, the resin layer is dissolved and removed, and the interlining etc. are released from the outer material.

The above-mentioned organic solvent varies depending on the type of thermoplastic resin, but for polyamide resin, Broch is used.

For alcohol, butanol, polyethylene/vinyl acetate resin, or polyvinyl chloride resin, halogenated hydrocarbons such as perchloroethylene are suitable.

The sewn product can be impregnated with the organic solvent using equipment similar to that used for ordinary dry cleaning.

The seam material obtained by the method of this invention has a good texture because the interlining or lining is separated from the outer material, and men's clothing, for example, can be evaluated as high-class men's clothing in the market. Moreover, it is easy to manufacture and does not require any skill.

Manufacturing costs will be lower. The present invention can be applied to the production of various sewn products such as men's clothing, jackets, blousons, and half coats whose outer material is woolen or knitted fabrics.

This invention will be explained in detail below.

Example 1 A non-woven fabric with a basis weight of 10 tsuru (trade name: Dynac S 020), in which an interlining made of cotton or rayon and having a basis weight of 100 u is intertwined in a spider web shape made of polyamide resin.

(Made by Kureha Fiber+1), cut into a predetermined shape.
After that, the periphery was sewn together using a sewing machine to make men's clothing.The men's clothing was then washed in a dry cleaning machine using propyl alcohol as a solvent for 40 minutes for 10 minutes. 1. The above-mentioned polyamide resin was eluted and released from the outer material of the interlining all-wool fabric.The obtained stitching amount was good in feel as rated as high-class men's clothing.

Example 2 Powdered resin made of polyethylene/vinyl acetate copolymer was sprinkled on the entire surface of an interlining material having a basis weight of 200 and made of T = Snake at a ratio of 10 to 10%, and this woolen interlining material was used as a cut woolen fabric outer material. Heat-bond it to the back side, and then sew the periphery using a sewing machine to make men's clothing.The men's clothing is then washed in a dry cleaning machine for 10 minutes at room temperature using perchlorethylene as a solvent. The resin was eluted and the interlining was released from the woolen outer fabric. It has a good texture that is evaluated as high-class men's clothing with a seam length of 7%4, and it is easy to manufacture because a complicated and skill-requiring interlining process can be omitted during the manufacturing process.
