| Abstract | ||
| This study focuses on cooking conditions of cotton linters using in Parchin chemical Company to achieve Optimum cooking conditions to provide special cooking table for every linter as above mentioned factory can adjust cooking conditions for all linters to obtain higher quality products. In this respect, 4 types of linters from Turkey, Uzbekistan, Turkmenistan, and Iran were provided from mentioned factory and pulped in two steps by 4 hours cooking time in every steps. Cooking conditions were done in 3 level 130, 150 and 160 °C; and various Alkali charge (AA %) in each step and measured cooking yield, ash content, microkappa, pentosan, copper number, carboxyl group, WRV, viscosity, alpha cellulose and acid insoluble materials for any conditions. Results showed that optimum cooking conditions were obtained for Turkey linter at 130 °C and AC%(8%-8%); Uzbekistan linter, 130 °C and AC% (12-%-4%); Turkmenistan linter, 130 °C and AC% (12%-4%); Iran linter, 130 °C and AC% (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). | ||
