Abstract

The invention provides a formula of pulp for producing paper straws. The pulp is prepared by mixing softwood pulp, hardwood pulp, recycled paper pulp and additives. Paper straws prepared from the pulphave high dry tensile strength and large dry elongation rate, has the wet tensile strength of 1Kn / m or more and wet elongation rate of 4 percent or more, cannot be softened if being soaked in water for half an hour or more, is environment-friendly, and can greatly meet the requirement of people for daily use.

Description

Technical field: [0001] The invention relates to the field of paper production, in particular to a formula for producing pulp for paper straws. Background technique: [0002] Nowadays, people's awareness of environmental protection is getting higher and higher, and the small plastic straws are difficult to be grasped by garbage disposers and then recycled. Therefore, the final fate of most plastic straws is to fall into landfills or float in on the ocean. Plastic straws that enter the waters are often eaten by sea turtles, seabirds, fish and other animals, causing the tragedies we have seen before. The plastic straws that continue to float on the sea will gradually break down, forming a large number of microplastic particles with a diameter of less than 5 mm. These toxic and harmful microplastic particles will also accumulate through the food chain and may eventually enter the human body, threatening human health. [0003] But the production technology of paper straw in t...
