At present, the flow pattern of flow pattern shoe materials is mainly formed by water transfer printing and digital printing. Among them, water transfer printing is a kind of solidcolor effect, which can form a fashionable color pattern, but this process is more serious for environmental pollution, and Digital printing technology is expensive and difficult to use in industrial production. At the same time, the above two processes are low in efficiency and high in cost, and both require secondary processing

Abstract
The invention provides a flow-line shoe material and a preparation method thereof, and the preparation raw materials of the flow-line shoe material comprise 92-99 wt.% of thermoplasticpolyurethane particles and 1-8 wt.% of flow-line master batch, wherein the flow line master batch is prepared from the following raw materials in percentage by weight: 40 to 50 percent of thermoplasticpolyurethane particles, 35 to 42 percent of polyethylene glycol terephthalate, 8 to 15 percent of maleic anhydridegrafting compatilizer, 1 to 3 percent of pigment and 0 to 10 percent of auxiliaries. Under the action of the maleic anhydridegrafting compatilizer, the thermoplasticpolyurethane particles and the polyethylene glycol terephthalate can be compatible to prepare the flow-line master batch, and the melting point of the flow-line master batch can be higher than that of the pure thermoplastic polyurethane particles due to the existence of the polyethylene glycol terephthalate. When the shoe material is formed, the thermoplastic polyurethane particles are melted before the master batch, and the master batch with the pigment is in a semi-melted state all the time, so that under the thrust of forming equipment, the thermoplastic polyurethane particles can be melted to drive the master batch to rub so as to generate irregular flow lines.
Description
technical field [0001] The invention belongs to the technical field of shoe materials, and in particular relates to a flow pattern shoe material and a preparation method thereof. Background technique [0002] With the improvement of people's requirements for the appearance of shoes and the performance of shoe materials, traditional single-color, single-density, two-color, and double-density polyurethane shoe material products can no longer meet people's increasing appreciation taste. Polyurethane flow pattern shoe material is a new type of fashionable single-density mixed-color shoe material, which is sought after by the industry because of its unique and strong sense of lines. It can be used for uppers or soles. At present, the flow pattern of flow pattern shoe materials is mainly formed by water transfer printing and digital printing. Among them, water transfer printing is a kind of solidcolor effect, which can form a fashionable color pattern, but this process is more se...
