Abstract

<P>PROBLEM TO BE SOLVED: To provide a substitute for a plastic product, capable of being degraded by microorganisms, even when thrown away and put in a natural environment after used. <P>SOLUTION: Yarn formed out of a biodegradable resin is produced by using the resin which is degradable by the microorganisms and comprises a natural polymeric (starch and modified polyvinyl alcohol), fermentatively produced (polyester produced by microorganisms), or chemically synthesized (aliphatic polyester, polylactic acid) resin as a raw material, and extruding and spinning pellets of the resin into the yarn. Further, a net, a cloth, a rope, and other products are produced by using the yarn as a raw material. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

The present invention is a pellet made of a biodegradable resin made from a natural polymer (starch and modified polyvinyl alcohol), a fermentation production system (microbe-producing polyester), and a chemical synthesis system (aliphatic polyester, polylactic acid). Yarn is produced from the raw material and processed according to the application.
This product is an item that is subject to the Green Purchasing Law, and is an environmentally friendly material that is applicable to petrochemical substitutes, clean manufacturing, clean materials, clean incineration, and clean disposal.

Currently used plastic products are not decomposed in nature when discarded after being used, and natural decomposition takes 200 to 400 years. When incinerated, toxic gases such as dioxins are generated to pollute the atmosphere, and the combustion value is high in calories and causes a rise in temperature in the atmosphere.

Problems to be solved by the invention

It is an object of the present invention to provide a product using a raw material that can be decomposed by microorganisms even if discarded in nature and can be used in place of a plastic product used in large quantities.

Means for solving the problem

The raw material of the present invention is a natural polymer (starch and modified polyvinyl alcohol), fermentation production (microbe-producing polyester), chemical synthesis (aliphatic polyester, polylactic acid) resin that can be decomposed by microorganisms. Even if it is disposed of in nature after use, it can be decomposed by microorganisms, and when it is incinerated, it quickly burns to ash dust, generates no harmful substances such as dioxins, has low calorie burns, and is affected by temperature rise in the atmosphere Can be reduced.

The invention's effect

The raw material of the present invention can be repeatedly produced with natural polymer (starch and modified polyester), fermentation production (microbe-producing polyester), and chemically synthesized (aliphatic polyester) resins. As a substitute for resources, the consumption of petroleum resources can be reduced and the amount of plastic products used can be reduced, contributing to environmental problems.

The microorganism-decomposable resin of the present invention uses natural polymer (starch and modified polyvinyl alcohol) fermentation production system (microbe-producing polyester) and chemical synthesis system (aliphatic polyester, polylactic acid). To manufacture.
In addition, when coloring, an environmentally friendly vegetable coloring agent is used.
In addition, plant-based materials are mixed in to prevent insects and soil dragons after installation.
A yarn is produced from the raw material produced in the above process by direct injection molding.
Products that are currently difficult to dispose of plastic products, those that can be disposed of but expensive to dispose of, those that cause secondary disasters due to disposal (generation of waste gas, generation of smoke, generation of waste odor), In addition, the government and the private sector will work on alternative products that are limited to those that will adversely affect the natural world by leaving them alone.
