Abstract

PURPOSE:To provide the shoe uppers having excellent air permeability, resilience, appearance and comfortability to wear by cutting and stitching the uppers material adhered with a front fabric and back fabric by a water soluble adhesive agent layer to form the shoe uppers, then washing the uppers with water to elute the adbesive layer and to separate the uppers to the front fabric and the back fabric. CONSTITUTION:The front fabric 11 and back fabric 12 of the uppers material 1 are constituted of cotton, woven fabrics and nonwoven fabrics which are properly combined according to the applications of the uppers material. The front fabric 11 and the back fabric 12 are stuck by the water soluble adhesive agent 13 such as starch powder or polyvinyl alcohol and are prepd. as the uppers material 1. The material 1 is spread and cut to meet the required shoe uppers by blanking dies, etc., and is stitched 2, by which the shoe uppers (a) are formed. The uppers (a) are washed with water to elute the adhesive agent layer 13 between the front fabric 11 and the back fabric 12 through the structure spacings such as weaves and stitches. The uppers are separated to the front fabric 11 and the back fabric 12 in a bag shape when the washed uppers are dried. The misregistration of the front fabric 11 and the back fabric 12 at the time of stitching is, therefore, prevented. The excellent air permeability and resilience and the good comfortability to wear are thus obtd.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a method of manufacturing a shoe cover.

(Prior Art) Conventionally, it has been commonly used to form a shoe cover by cutting and sewing a laminated fabric made by bonding an outer fabric and a lining fabric with a rubber adhesive.

However, the shoe cover obtained in this manner has a drawback of poor breathability and flexibility because a rubber adhesive layer is formed between the outer fabric and the lining fabric.

Conventionally, in order to impart breathability and flexibility to shoe covers, a method of forming bag-shaped shoe covers by overlapping separately cut outer and lining fabrics and sewing the periphery has also been commonly practiced. There is 1
When sewing the outer fabric and the lining fabric, the outer fabric and the lining fabric tend to shift from each other, which significantly reduces the sewing work and increases costs.Moreover, if the outer fabric and the lining fabric are sewn with misalignment, Or, the lining fabric had creases formed, and there were points that significantly deteriorated the appearance and comfort of the wearer.

(Problems to be Solved by the Invention) The present invention aims to provide a shoe cover with excellent breathability, flexibility, appearance, and comfort using a simple method.

(Means and Examples for Solving Problems) Below,
To explain this invention with reference to the drawings showing the state of implementation of the invention, the invention involves cutting a cover material 1 made by bonding an outer fabric 11 and a lining fabric 12 with a water-soluble adhesive layer 1, and sewing the periphery thereof. Summary of the Invention The present invention provides a method for producing a shoe cover, which is characterized in that after forming a shoe cover (a), the shoe cover (a) is washed with water to dissolve the adhesive layer 13 and separate the outer fabric 11 and the lining fabric 12 into bag shapes. That is.

In this invention, the outer fabric 11 and the lining fabric 12 of the cover material 1 are made of natural fibers such as cotton, cotton, hemp, artificial fibers such as viscose rayon, acetate, cupro, polyamide, polyester, polyolefin, polyvinyl, etc. It is composed of nine knitted woven fabrics or non-woven fabrics using one or more types of synthetic fibers such as polyurethane based, as appropriate for the purpose of shoe coverings. And these outer cloths 11
The lining cloth 12 is made of wheat flour, rice flour, corn flour, starch tea such as dextrin, protein-based material such as casein, funori,
They are bonded together by an adhesive layer 13 composed of a water-soluble adhesive such as a seaweed adhesive such as agar, a cellulose adhesive such as hydroxyethyl cellulose or carboxymethyl cellulose, or a polyvinyl alcohol adhesive, thereby preparing the cover material 1.

The shoe cover material 1 prepared in this way is developed and cut according to the required shoe cover using a punching die, etc., and its periphery is hemmed using a sewing machine or the like in a conventional manner, and if necessary, with edge tape 3. Then, sewing 2 is performed to form the shoelace a.

The shoelace a formed in this way is washed with water and the outer fabric 1 is washed with water.
The adhesive layer 13 interposed between the outer fabric 11 and the lining fabric 12 is eluted through the interstitial gaps such as the textures and stitches of the outer fabric 11 or the lining fabric 12, and is dried to separate the outer fabric 11 and the lining fabric 12 into a bag shape. be done.

In this invention, if jeans are used as the outer fabric 11, it is possible to perform the decoloring process peculiar to jeans at the same time when washing with water, thereby further increasing the commercial value of the shoe cover a. The shoe cover a of the present invention thus completed can be used as a shoe by attaching a sole integrally molded by an injection molding method or a pre-molded sole to the lower periphery by an adhesive method or the like using a conventional method. be completed.

(Effect of the invention) The shoe cover a of this invention has the outer fabric 11 and the lining fabric 12 as described above.
Since the outer fabric 11 and the lining fabric 12 are pasted together, the outer fabric 11 and the lining fabric 12 can be developed and cut at the same time into the required shoe lace shape, and furthermore, the outer fabric 11 and the lining fabric 12 will not shift relative to each other when the shoe lace is sewn. The sewing work is efficient because there are no folds, and the appearance is good because there are no creases formed on the outer fabric or the inner fabric. Furthermore, after the shoes are sewn, the adhesive layer 13 is eluted by washing with water.
Since the outer fabric 11 and the lining fabric 12 are separated into a bag-like shape, the shoe has excellent breathability and flexibility, and is comfortable to wear.
