A preparation method of degradable microfiber-based tea packaging material

Abstract

The invention relates to the preparation technology of micro-nano materials, and aims to provide a preparation method of degradable ultrafine fiber-based tea packaging materials. It includes: preparing potato starch solution and polyvinyl alcohol aqueous solution respectively, adding plasticizer after mixing; continuously stirring the mixed solution for 2 hours in a water bath at 50°C to obtain spinning solution; preparing fiber membrane by centrifugal spinning method; The film is cross-linked with a cross-linking agent at 130°C; it is moved to a hot rolling mill for hot rolling to obtain a degradable fiber-based packaging material. The invention uses starch and polyvinyl alcohol as spinning raw materials, the preparation method is simple and easy, the process conditions are easy to realize, and starch is used as the main component, so the cost is low, and it is an ideal material for replacing filter paper tea bags with high energy consumption and complicated production process . The prepared microfiber has good degradability and biocompatibility, and is an ideal material to replace most of the existing non-woven tea bags prepared from non-degradable synthetic polymers.

Description

A kind of preparation method of degradable superfine fiber-based tea packaging material technical field The present invention is about micro-nano material preparation technology, particularly a kind of degradable superfine fiber-based tea packaging material material preparation method. Background technique Historically, tea has always been the mainstream drink in many countries and regions, and has been favored and loved by consumers at home and abroad. Love. In recent years, tea consumption has developed in many countries. Fee groups are also increasingly diverse. Today, with the great improvement of people's living standards, different age groups are more interested in tea products. The choices are also quite different. For example, young people tend to drink tea, while middle-aged and elderly people tend to be fashion, high-end, Health and other tea products. Tea packaging material is very important to the development of tea products, and its main packaging...

AI Technical Summary

Problems solved by technology

At present, the tea packaging bags used at home and abroad are mainly filter paper and non-woven fabrics, which have the disadvantages of cumbersome production process, serious pollution, and lack of degradability and biocompatibility, which may endanger human health.
