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).Esmaeil Rasooly GarmaroodyHossein FoladiHossein Jalali trshiziAbas ChaharmahaliRegional Information Center for Science and Technology (RICeST)articleCooking temperatureAlkali chargelinterAlpha celluloseForestrySD1-669.5FAتحقیقات علوم چوب و کاغذ ایران, Vol 30, Iss 4, Pp 618-631 (2015)
