Abstract

Abstract: Nowadays in paper business sector there is only tissue paper business where growth rate is in double digits since five years consecutivelywhich motivates and encourage entrepreneurs to take up the business with more vigor. Tissue paper is generally categorized in four grades -Napkin grade paper, Toilet grade paper, Facial grade paper and Towel grade paper. Due to higher consumption of towel grade tissue paper at several outlets like offices, educational institutions, aesthetic purposes, common toiletries andhospitalities.This towel grade is being used for wiping wet hands, to meet out these requirements we need to develop high strength in towel grade tissue paper.This study is being conducted to high strength in towel grade tissue paper with application of DSR and WSR. Chemical additives play essential role in production performance of towel grades tissue paper. A significant amount of their tensile strength are retained by wet and dry strength resins .Mixed bleached pulp was collected from pulp mill of a well-known industry. It was refined to different degrees of freeness (°SR) i.e. 25, 30 and 35. Handsheets of pulp refined to different extent, were prepared and physical properties investigated. Based on the specific energy consumption of refiner and the pulp strength properties obtained, pulp freeness with 35°SR were selected for further study. DSR was added in three different doses i.e.2.0, 3.0&4.0 kg/ton and WSR in dosages of 15, 25 & 35 kg/t of pulp. Breaking length and wet strength were enhanced by 32 % and 42 % respectively. On account of this, significant reduction in paper breaks observed on paper machine, which further improved machine runability, reducing downtime. Productivity of machine was enhanced along with supreme quality of towel (interfold) grade tissue paper.
