AI Technical Summary

Technical Problem

The thin film coating on bag fabrics is prone to damage, cracking, or peeling due to contact and impact during prolonged use, affecting its service life.

Method used

An abrasion-resistant layer comprising PE resin, modified corn fiber, coumarone resin, modified diatomaceous earth, dioctyl sebacate, antioxidant, calcium stearate, and rosin is mixed and coated onto the base layer of the fabric to form an abrasion-resistant layer, thereby improving the abrasion resistance and stability of the fabric.

Benefits of technology

It improves the abrasion resistance and service life of the fabric, prevents wear and tear of the film coating, and extends the service life of the bag fabric.

Abstract

This application discloses a fabric for bags and a method for preparing the same, belonging to the technical field of bag fabrics. The bag fabric includes a base layer, an adhesive, and an abrasion-resistant layer. By weight, the abrasion-resistant layer comprises the following raw materials: 60-70 parts PE resin, 15-20 parts modified corn fiber, 4-8 parts coumarone resin, 10-18 parts modified diatomaceous earth, 2-4 parts dioctyl sebacate, 2-6 parts antioxidant, 0.5-1 part calcium stearate, and 1-1.5 parts rosin. The abrasion-resistant layer prepared by this application has good mechanical strength and abrasion resistance. When applied to the surface of the bag fabric, it is not easily worn or torn, thus extending the service life of the bag fabric.
