The Green Preparation and Properties of Recycled Pulp of Waste Cotton Textiles
With the increasing production and consumption of textiles,tens of millions of tons of waste textiles are generated every year,causing huge waste of resources and environmental pollution.The existing waste textile recycling technology is mainly based on physical methods,and the recycling rate and the product quality are relatively low.Therefore,it is urgent to develop new waste textile recycling methods.In this paper,a new method of preparing recycled cotton pulp fiber from waste cotton textile is developed.The polymerization degree,morphology and structure of the recycled pulp can be effectively regulated by changing the preparation process of the recycled pulp.The efficient preparation of the recycled cotton pulp can be realized through the processes of cooking and pulping.The proposed method can alleviate the challenge of insufficient raw materials of primary pulp,and have a wide application prospect in the fields of papermaking,textile,and functional fiber preparation.
