Description

Manufacturing process of multi-layer-sole cloth shoes

Technical Field

The invention belongs to the technical field of shoes, mainly belongs to the technical field of manufacturing industries of cloth shoes, and particularly relates to a manufacturing process of cloth shoes and canvas shoes.

Background

The multi-layer sole is a sole which is formed by processing multi-layer cloth, no chemical substance is added, pure natural cotton cloth is adopted, the health preserving, sweat discharging and ventilating effects are achieved, the inside of the shoe can be dry and comfortable when the shoe is worn by the multi-layer sole cloth shoe, the foot is not smelly, foot diseases are prevented from breeding, the extensibility and adaptability of the foot to the surrounding environment can be enhanced, the obvious comprehensive prevention and treatment effects on beriberi, cervical vertebra and various waist soreness and leg pains are achieved, and the foot and whole body maintaining effect is achieved. In the field of cloth shoe manufacturing at present, most traditional cloth shoe manufacturers still adopt a manual shoe stitching technology to combine the upper surface of the cloth shoe with the multi-layer sole, and part of the cloth shoe manufacturers adopt an injection molding process to complete cloth shoe production. The traditional stitching technology mainly comprises the step of manually stitching and forming the upper and the sole, which is an ancient hand-stitched cloth shoe manufacturing technology, the cloth shoe upper surface and the multi-layer sole are manually stitched and stitched together, stitch codes for stitching the shoe are not only neat in spacing, but also the combination of the upper and the multi-layer sole is tight and full. The shoe stitching is divided into three methods of positive stitching, negative stitching and positive stitching, wherein one stitch cannot be seen on the appearance of the shoe by the reverse stitching and the positive stitching, the traditional shoe stitching process has high requirements on professional shoe stitching mechanics, the training time of technicians is long, and most of the traditional shoe stitching process is in the age of more than 45 years of technicians. Meanwhile, the splicing requirement on the upper surface structure of the shoe is simple, and the integral attractiveness of the finished cloth shoe is greatly related to the sole stitching. Due to the open rapid development of the reform in China, the traditional cloth shoe production has been reduced to the workshop type production or replaced by the modern injection molding shoe making process. The advantages of the multi-layer sole cannot be completely retained. The conventional positive, reverse and clear stitching method cannot improve the production yield of the cloth shoes better. In addition, the traditional injection molding process mainly adopts machine processing, after the upper surface is pricked on the aluminum last, the upper surface is generally directly injected by a turntable machine, and the injection molding process has the characteristics of no smell, low price, high elasticity, portability and durability. However, the shoes manufactured by the injection molding process are difficult to shape and are not delicate enough, and the manufacturing fineness is relatively deficient, and in the sole injection process of the shoes, the upper fabric is easy to form uneven blocks in the soles, so that the comfort is affected, and the shoes are generally only suitable for orders with single sole styles and are mainly used for leisure and sports styles.

Another conventional gluing process, also called cold gluing, is a process of joining an upper, an insole, and an outsole together with an adhesive. Due to the difference of the materials of the upper and the sole, the types and properties of the adhesives used are different, such as neoprene adhesive, polyurethane adhesive, SBS adhesive, etc. The gluing process has the advantages of simple process, short production period, high production efficiency, low manufacturing cost, quick change of colors and varieties and easy expanded reproduction, so the gluing process is the most applied assembly process in the current shoe manufacturing industry and accounts for more than 80 percent of the total weight of shoe products. The technology is most applied to leather shoes and sports shoe products. The assembly method of the cold bonding process has the advantages of few processes, high efficiency, close connection among all the processes, reduction of waiting in the middle process, great improvement of the assembly forming rate of the shoes, and solving of the problems that the assembly forming of the shoes is often disordered and the forming quality of the shoes is seriously influenced due to the complex assembly process and many processes of the existing shoes. Prior art patent document CN106983235A discloses a cold-bonded shoe molding process, which specifically comprises: forming a shoe last upper body, specifically shaping a heel, threading a shoe lace, steaming and wetting an upper surface, coating white glue, pulling a front upper, pulling a waist upper and a back upper, drawing a line at a fixed point, and vulcanizing and stabilizing; pretreating the upper body with the shoe last and the sole, namely, roughing the net foot and the sole, removing scraps, wiping water, feeding into a second oven, feeding primary surface glue/bottom glue into a third oven, feeding secondary surface glue/bottom glue into a fourth oven; cold-bonding the upper and the sole, namely, matching, aligning to a fixed point, manually laminating by pressure, mechanically pressing, freezing and stabilizing; the shoelace is untied, the shoe tree is pulled out and the arrangement is carried out. Guarantee the group's end through the fixed point setting-out and combine the position accuracy, easy operation, standard operation avoid shoes crooked to make group's end combine more firm stable, durable through processes such as multichannel rubber coating, multichannel stoving and net foot processing and mend glue, make simultaneously that the bonding interface between well welt, net foot and the sole is more level and more firm, promote feel and the comfort level of wearing. However, the above documents mainly disclose a conventional cold-bonding process for making shoes suitable for common shoes, which still has certain disadvantages for the shoes with multi-layer soles, and damages the comfort of the multi-layer soles.

Considering the above factors in a comprehensive manner, as the manual stitching must be performed by using the awl and the coarse cotton thread, the upper surface is easily damaged in the stitching process, which cannot be compensated, especially for high-end fabrics, the fabric and the style structure of the upper surface are limited greatly, and the fabric selection and the style design are difficult; in particular, the manual shoe stitching method is easy to cause the problems of inconsistent left and right foot appearances and high defective rate. The injection molding process has the problem of lack of comfort and fineness in shoe making. The method has the advantages that the advanced cold-bonding shoe making process is effectively used for reference, the cloth shoe making process is combined, the technical innovation purpose is to improve the cloth shoe production efficiency and the high-quality product rate and keep a plurality of advantages of the multi-layer-sole cloth shoes, the multi-layer-sole cloth shoe cold-bonding pressing making process is effectively innovated, the uncertainty and unstable factors in the manual shoe attaching process are effectively solved, and the technical process more suitable for modern cloth shoe production is found.
