Nonwoven Production from Waste Rice Straw by Using Enzymatic Method

ABSTRACT

In this study, the nonwoven fabric is produced by rice straws to utilize agricultural organic waste. Rice straws dried after harvest are pretreated with NaOH, pectinase enzyme and wetting agent. Washed and softened fibers are cut at 4–5 cm staple length, blended in carding engine with cotton at 9/1 ratio. By carding band and needle punch process nonwoven fabric is obtained. SEM, EDX and FTIR analyses are applied on the fabric. Product’s inspection verified that pretreatments provided smoothness, removed noncellulosic substances, and decreased hydrophobic structure. Thus, a new nonwoven material to be used in textile is produced.

摘要

本研究以稻草为原料，利用农业有机废弃物生产非织造布。用NaOH、果胶酶和湿润剂预处理稻草收获后干燥。洗涤和软化的纤维在4～5厘米的短纤维长度下切割，在梳棉机中以9/1的比例与棉混纺。通过梳理带和针刺工艺获得无纺布。将SEM、EDX和FTIR分析应用于织物上。产品检验证明，预处理提供了光滑性，去除了非纤维素物质，降低了疏水结构。因此，生产用于纺织的新型非织造材料。
