Embodiment Construction

[0007] The invention relates to a method for making elastic magic shoes, which is characterized in that the upper surface of the shoe is made of elastic Lycra cloth woven by several slender Lycra fibers similar to rubber bands. The production technology of the upper surface is: dot hot melt adhesive dry composite technology: the upper is made of double-layer elastic Lycra cloth and 0.1-0.3mm sponge, and the hot melt adhesive is made of dot hot melt adhesive breathable composite technology. Spread evenly on the lycra cloth and sponge, control the drying temperature at 80-100 degrees through the laminating machine, and control the pressure of the scraper at 200-400kpa, and press them together after the adhesive is dry. Through the composite of double-layer elastic lycra cloth and sponge, the upper and lower sides of the upper can be expanded by 35% to 55% instantly, and the left and right sides can be expanded by 25 to 45% according to the shape of the foot.

Abstract

The invention discloses a method for manufacturing elastic hook-and-loop shoes. The method is characterized in that shoe upper surfaces are made of elastic Lycra cloth, and a plurality of slim Lycra fibers similar to rubber bands are woven to form the elastic Lycra cloth. The method includes a technique for manufacturing shoe uppers and a technology for processing materials of the Lycra cloth. The technique for manufacturing the shoe uppers includes compounding the double-layer elastic Lycra cloth with sponges, to be more specific, uniformly coating hot-melt adhesive onto the Lycra cloth and the sponges by the aid of a point hot-melt adhesive dry type compounding technique, enabling the drying temperatures to range from 80 DEG C to 100 DEG C under the control by the aid of compounding machines, enabling the pressures of scrapers to range from 200kpa to 400kpa under the control, and integrally laminating the elastic Lycra cloth and the sponges after the adhesive is dried. The size of each sponge ranges from 0.1mm to 0.3mm. The double-layer elastic Lycra cloth and the sponges are compounded with one another, accordingly, the upper sides and the lower sides of the shoe uppers can be instantly expanded by 35%-55%, and the left sides and the right sides of the shoe uppers can be enlarged by 25%-45% according to the foot types of wearers. The technology for processing the materials of the Lycra cloth includes carrying out pressing processing on press stubble positions of the Lycra cloth by the aid of a pneumatic pressing technique, to be more specific, brushing adhesive at certain positions of the Lycra cloth at first, regulating the temperatures by the aid of pneumatic pressing machines to enable the temperatures to range from 120 DEG C to 140 DEG C, and performing pressing processing on the certain positions of the Lycra cloth for 5-10 seconds. The distances from the certain positions of the Lycra cloth to the edges of the press stubble positions of the Lycra cloth range from 3mm to 5mm. The method has the advantages that the edges of the press stubble positions are flat and compact and are not loose, and the component adhesion firmness can be guaranteed.

Description

technical field [0001] The invention relates to a footwear daily necessities, in particular to a method for making elastic magic shoes. Background technique [0002] At present, China has entered an aging society. Many middle-aged and elderly people have gone through years of vicissitudes. Their feet have been worn out for many years and improper shoes have caused serious deformation of their feet. Among them, the most prominent problems are: hallux valgus, arch collapse, toe joints Deformation, high instep, etc., these common foot shapes are jokingly called "Transformers feet" by medical experts. Experts remind: for middle-aged and elderly people with deformed feet, it is very important to choose a pair of shoes without squeezing. However, there are very few shoes specifically for the elderly with collapsed arches and deformed toes. Older shoes are increasingly marginalized due to high functional requirements and low profits.
