Vessels White oak cell types, fibers, rays, and vessels, were isolated from high-yield chemimechanical, neutral Rays sulphite semichemical (NSSC), and kraft pulps. Milled wood lignins (MWL) from NSSC fiber and ray Fibers cell fractions analyzed by ultraviolet and infrared spectroscopy were found to have similar syringyl/ Cell wall guaiacyl ratios. Methoxyl analyses of MWL’s were also similar an...

Hibiscus cannabinus, Cannabis sativa, and Hibiscus sabdariffa, fast growing productive annual plants, could provide fiber necessary to partially alleviate the world’s fiber deficit. The present study aimed at producing high yield pulp and the best mechanical strength properties with minimum impact on environment by SAS-AQ, and NSSC-AQ pulping processes. A total alkali of 13% (as Na2O), an alkal...

این تحقیق با هدف بررسی اصلاح مایع پخت فرآیند خمیرکاغذسازی نیمه شیمیایی سولفیت خنثی (NSSC) با اعمال تغییرات درصد مواد شیمیایی، افزایش میزان قلیائیت و تغییر زمان پخت برای تولید خمیرکاغذ شبه شیمیایی (سولفیت قلیایی) انجام شده است. در بین خمیرکاغذهای تولیدی، بهترین ترکیب با توجه به قلیائیت باقی‌مانده قابل قبول (11 pH >) و عدد کاپای قابل قبول (حدود 17) و کمترین مقدار وازده انتخاب شد. خمیرکاغذ سولفیت ...
