THE EFFECT OF VARIOUS SIZING AGENTS ON THE PHYSICAL AND MECHANICAL PROPERTIES OF PACKAGING PAPERS CONTAINING TEXTILE FABRIC WASTE

Résumé fourni par la source

This article studies the issues of improving the physical and mechanical properties of packaging papers containing textile fabric waste (TWF), the effective use of secondary and alternative raw materials, and stabilizing the strength indicators of paper products. The main goal of the study is to increase the mechanical strength of experimental packaging papers containing TWF and improve the efficiency of fiber bonding in the paper pulp. For this purpose, sizing agents based on hydroxypropylmethylcellulose (GPMS) and modified cationic starch (MCS) were added to the paper pulp in an amount of 2%, experimental paper samples were prepared, and their main physical and mechanical indicators were studied. The results obtained showed the possibility of producing high-strength packaging papers using TWF.
