Abstract

PURPOSE: Provided is a method to compress and vulcanize rubber piece to fabric which compresses and vulcanizes the projected piece of the bottom piece to the fabric to reduce the weight of shoes so that it improves wearing effect. CONSTITUTION: The method to compress and vulcanize the rubber piece to the fabric is characterized by comprising the steps of: (i) treating the fabric like cloth, natural or synthetic leather by resin to coat gaps between strands of the fabric and gaps between tissues of leather or upper and lower surface of the leather by a thin film; and (ii) compressing and vulcanizing the rubber piece to the fabric.

Description

Work method of attaching (pressing) vulcanizing (vulcanizing) rubber pieces to fabric (natural, synthetic leather) {omitted}

The present invention is a shoe sole currently in use as shown in Fig. 1 AB, both the flat portion and the protruding piece of the adhesive portion of the upper or midsole are made of a single piece of rubber (Figs. 1A, B1.2) per sole pair It was invented to minimize the weight of shoes by reducing its weight to 100-G within 400-500G on average.

Shoe uppers are used by pouring TPR or silicone fluid on the nose of shoes or by cutting rubber plates and sewing them with a sewing machine. However, TPR or silicon is cracked in TPR at temperatures below zero, or aging occurs rapidly due to DOP ejection. In other words, the silicon discolors in daylight and claims.

In addition, as shown in Fig. 1 AB, the conventional shoe sole is made of rubber dough (600-700G) in a thick MOULD, and taken out like a carp bread (Fig. 1B) by a high-pressure press, so that the entire sole is about 400-500G even if the sole is removed as rubber. The weight will eventually weigh the entire shoe.

However, as shown in Fig. 2A.B, only the protruding pieces of the sole (Fig. 2A3, B6.8) after the resin treatment (DIPPING) are used on the fabric (fabric, natural, synthetic leather). It can be attached (compressed) to vulcanized (vulcanized), so that the weight of the sole is less than 100G, which ultimately reduces the weight of the entire shoe, improving the wearer's wearing comfort. After the resin treatment (FIG. 3A9.10) to the fabric, the rubber is attached (compressed) vulcanized (vulcanized).

The present invention penetrates the resin into the fabric (cloth, natural, synthetic leather) (Fig. 2A4, B5.7, Fig. 3A9, B11), and between all the tissues of the fabric (textile, natural, synthetic leather). A thin film of 1 M / M or less is coated on the upper and lower surfaces, and rubber is attached (compressed) and vulcanized (vulcanized) to the fabric (natural, natural or synthetic leather).

As described above, when manufacturing shoes with the ultra-light shoe sole produced according to the present invention, the weight of the shoes is significantly lighter when the user wears and wears them to improve the user's comfort as much as possible.

In addition, the shoe upper is to improve the yellowing phenomenon of the aging of the TPR and the sun exposure of the silicon at the same time to the nose and side work of the shoe.

Claims (1)

The sole of the shoe that touches the sole of the shoe is made of rubber, and the upper or midsole's adhesive part is bonded to the fabric (cloth, natural, synthetic leather) after the resin treatment. Ultra-light shoe soles and shoe uppers with TPR aging and silicone upper with improved yellowing of silicone (textile, natural, synthetic leather) after resin treatment (spray or impregnation) with rubber (vulcanized) Manufacturing method.
