Abstract

This study focuses on cooking conditions of cotton LINTERs using in Parchin Chemical Company to achieve optimum cooking conditions and provide special cooking table for every LINTER to enable the above mentioned factory to adjust cooking conditions for LINTERs to obtain higher quality products. In this respect, 4 types of LINTERs from Turkey, Uzbekistan, Turkmenistan, and Iran were collected from the mentioned factory and pulped in two steps using 4 hours cooking time in every step. Cooking conditions were selected in 3 levels of 130, 150 and 160oC; and various Active ALKALI CHARGE (AA%) in each step and then the cooking yield, ash content, micro kappa, pentosan, copper number, carboxyl group, WRV, viscosity, ALPHA CELLULOSE and acid insoluble materials were measured for each set of conditions. Results showed that optimum cooking conditions for Turkey LINTER were at 130oC and AA% (8%-8%); Uzbekistan LINTER, 130oC and AA% (12-%-4%); Turkmenistan LINTER, 130oC and AA% (12%-4%); Iran LINTER, 130oC and AA% (14%-2%). Hence, based on cooking conditions, the LINTERs can be classified into 3 grades such as Grade 1 (Turkey), Grade 2 (Uzbekistan and Turkmenistan) and grade 3 (Iran).
