废蚕丝纤维抄造书画纸的生产工艺研究

Research on the production process of painting and calligraphy paper with waste silk fiber

以废蚕丝短纤维为原料,经脱胶/脱色处理、碱处理、漂洗和打浆等碱法制浆工艺可制得性能良好的蚕丝纸浆。文章通过光学显微镜和扫描电镜(SEM)对处理前后蚕丝纤维的表面形态和表面形貌进行分析发现,经打浆机以“轻—重—轻”下刀方式打浆,蚕丝纤维的分丝帚化和细纤维化效果好,其中NaOH质量分数应低于2%,打浆度宜控制在30~40°SR;明胶可作为蚕丝书画纸的施胶剂,明胶质量分数为1.0%时,纸张的物理强度最大;采用传统的手工捞纸等工序制得100%废蚕丝书画纸产品,以及配加20%、50%夹江书画纸竹浆制得蚕丝竹纸书画纸,其性能指标均满足国家标准的要求。

Using waste silk staple fiber as raw material,silk pulp with good properties can be produced through alkali pulping processes such as degumming/decolorizing treatment,alkali treatment,rinsing and beating.The surface morphology of silk fibers before and after treatment have been analyzed in the paper by optical microscope and scanning electron microscope(SEM),it was found that the effect of fibrillation and fine fibrillation of the silk fiber is good after the pulping with a mode of"light-heavy-light"by the beater.The mass fraction of sodium hydroxide should be less than 2%,the beating degree should be controlled at 30~40°SR.Gelatin can be used as sizing agent for silk paper,when the mass fraction of gelatin was 1.0%,the physical strength of silk paper was the biggest.The painting and calligraphy paper,which was manufactured with 100%waste silk with traditional manual fishing paper and other processes,and added with 20%and 50%bamboo pulp which was used for Jiajiang,can reach the performance indicators of the national standard.
