Starch-polyamide fiber blended full-degradable zip lock bag and preparation method thereof

Abstract

The invention discloses a starch-polyamide fiber blended full-degradable zip lock bag and a preparation method thereof. The zip lock bag is prepared from, by weight, 50-60 parts of polyamide fibers, 8-15 parts of calcium carbonate, 1-4 parts of nanometer titania, 10-20 parts of benzoin ethyl ether, 7-9 parts of nano-motmorillonite, tetrabutyl titanate, 12-14 parts of chitosan, 60-65 parts of corn starch, 2-3 part of gelatin, 1-2 parts of magnesium stearate, 13-15 parts of acetyl tributyl citrate, 1-1.5 parts of 2,6-di-tert-butyl-4-methylphenol, 4-6 parts of 3-hydroxybenzoic acid, 1-2 parts of laurinol sulfate and 4-6 parts of plant saponin. The materials of the starch-polyamide fiber blended full-degradable zip lock bag are used for making food packing bags and the like, the antibacterial property to escherichia coli and staphylococcus aureus reaches 95% or above, the antibacterial time is long, further treatment on the composite material cannot weaken the antibacterial property, the validity period of antibacterial property is long up to one year or above, waste products can be automatically decomposed under the action of oxygen enrichment and microorganisms and finally generate carbon dioxide and water, and the bag is ecological and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of plastic films, in particular to a starch-polyamide fiber blended fully degradable compact bag and a preparation method thereof. Background technique [0002] In recent years, due to the increasingly serious "white pollution" caused by waste plastics that are difficult to degrade, it has attracted widespread attention from all over the world. Countries around the world have successively issued relevant laws and regulations restricting or prohibiting the use of non-degradable plastic packaging. On the other hand, because petroleum, the raw material for making traditional plastics, is a non-renewable resource, it will be exhausted with the massive use of human beings. Therefore, it is imminent to develop environmentally friendly plastics that use renewable resources as raw materials and are degradable. [0003] Polyamide fiber has a series of excellent properties such as good elasticity, good wear resistance...

Problems solved by technology

Due to the unreasonable industrial structure and the low development, adaptability and market competitiveness of new varieties such as differentiated, functionalized and high-performance fibers in my country, it is difficult to meet the development needs of the textile industry.

Most of the differentiated fibers currently developed are first- and second-generation fiber products with single functions, while new types of chemical fibers with various functions and their applications have just started, and no series of products have been formed and the quality of the varieties is unstable.
