前言本市造纸行所用棉浆历来都是采用淡碱水或石灰蒸煮。主要是为了分离棉籽壳,脱掉棉脂,适应后续的工艺处理,但废液处理困难较大。棉纤维的原料特性是甲种纤维较高、半纤维素及多糖、木素较低,所以收获率高,面抄片强度则稍低。根据集中制浆中使用多种原料(包括稻麦草,木片,棉短绒)和多种工艺的情况,设想用草浆或木浆的黑液蒸煮棉浆。因木浆黑液所含残碱较高,接近棉浆 Preface The cotton used in the city’s papermaking line has always been to use light alkali or lime cooking. Mainly in order to separate cottonseed hulls, take off cotton, to adapt to follow-up process, but the waste treatment more difficult. The raw material characteristics of cotton fiber is a higher fiber, hemicellulose and polysaccharides, lignin is low, so the high rate of harvest, flour sheet strength is slightly lower. Based on the use of various raw materials (including rice straw, wood chips, cotton linters) and various processes for centralized pulping, it is envisaged that cotton slurries may be cooked with a black liquor of straw or wood pulp. Wood residue black liquor due to higher residual alkali, close to cotton pulp
