Problems solved by technology

Regenerated cotton is made from waste foam, industrial scraps, scraps from shoe factories and waste foam from foam factories. In the production process of existing recycled cotton devices, ordinary cotton is used as a product for processing. , the consumption of raw materials is relatively large, the cost is high, and the products produced have poor hygroscopicity and airtightness, which cannot meet the production requirements of recycled cotton

Abstract

The invention discloses a vertical regenerated cotton device and a production technology, and relates to the field of regenerated cotton production methods. The technology comprises the following steps: (e), discharging mixed and foamed waste polyurethane mixture into a reaction die machine, and compressing in the reaction die machine (3) in a mechanical manner; (f), passing the compressed waste polyurethane mixture through steam so as to molding immediately; (g), stripping molded finished product from a die; and (h), cutting the stripped finished product by a circle cutting machine to obtain a product. The device is simple in structure and convenient to operate, consumes less raw material, lowers the cost, and can realize rapid molding and cutting by using special polyurethane and performing steam heating; and moreover, the produced product has higher ventilation property, higher antibacterial property, higher moisture absorption property and high elasticity.

Description

technical field [0001] The invention relates to the field of regenerated cotton production methods, in particular to a vertical regenerated cotton device and a production process. Background technique [0002] The country vigorously advocates a circular economy, and the production and utilization of recycled cotton embodies the spirit of the reform. At the same time, recycled cotton has also brought new business opportunities to the shoe material industry. Many companies aim at the market and seize opportunities. The discarded scraps of shoe factories have been turned into treasures, and the market has been vigorously explored, making recycled cotton a new profit enhancement point for the company. Regenerated cotton is made from waste foam, industrial scraps, leftovers from shoe factories and waste foam from foam factories. In the production process of existing recycled cotton devices, ordinary cotton is used as a product for processing. , the consumption of raw materials i...
