PAGE 26 竹原纤维的制备工艺研究 摘要: 再生竹原纤维，简称为竹原纤维。竹原纤维作为一种品质优良的纺织材料，己引起广大消费者、生产者和研究人员的关注。本实验主要采用化学处理的方法对竹子进行化学处理，包括双氧水和尿素试剂的预处理液对竹子进行处理，然后在用一定浓度的NaOH、Na2SO3、Na2SiO3、蒽醌类复合助剂的混合液对竹子进行煮练处理，以及不同比例浓度的助剂对煮练效果的影响，最后在水洗分离出竹原纤维，比较分析出最佳的工艺处理的参数、试剂比例，采用最佳工艺实验。 即预处理液中H2O2质量浓度3 g/L，尿素8 g/L；碱处理液中NaOH 10 g/L、Na2SO3 2％、Na2SiO3 2％、蒽醌类复合助剂1％；温度80℃；处理时间3h 关键词：竹原纤维；预处理；煮练；化学处理。 The research of bamboo fiber for preparation technology Abstract: Original renewable bamboo fibers has been known as the original bamboo fibers. Bamboo fibers as a quality original textile materials has caused large numbers of consumers, producers and researchers concerned. This study mainly uses chemical treatment methods for chemical treatment of bamboo, including hydrogen peroxide and urea reagent pretreatment on bamboo processing, And then with a certain concentration of NaOH, Na2SO3, Na2SiO3, anthraquinones complex mixture of additives to scouring the bamboo processing, and the proportion of different concentrations of additives on the scouring effect of the final washed in isolated natural bamboo fiber, Comparative Analysis of the best handling of the parameters of reagents, the use of best technology experiments. Then, in the pretreatment of H2O2 concentration 3 g / L, urea 8 g / L; alkali processing solution NaOH is 10 g / L, Na2SO3 is 2%, Na2SiO3 is 2% and anthraquinones of one percent additives, temperature is 80 ℃; Processing time is 3 h Key words: natural bamboo fiber；pretreatment；scouring ；chemical treatment 目 录 摘要 ……………………………………………………………………………… Ⅰ Abstract ……………………………………………………………………………Ⅱ 1 前言 ……………………………………………………………………………01 1.1 竹原纤维的发展概况 ………………………………………………………01 1.2 竹原纤维结构与性质 ………………………………………………………02 1.2.1 何谓“竹原纤维” ………………………………………………………02 1.2.2 竹纤维的分类 …………………………………………………………… 1.2.3 竹原纤维原料 ……………………………………………………………03 1.3 竹原纤维特点及用途…………………………………………………………03 1.3.1 竹纤维的结构与性能特点…………………………………………………03 1.3.2 竹纤维的性质 ……………………………………………………………04 1.4 竹纤维产品的研发现状 ……………………………………………………06 1.5 竹纤维产品的前景展望 ……………………………………………………0
