Research On The Extraction Process Of Augarcane Rind Fiber And The Fiber's Properties

The global energy is shortage, the development of synthetic fibers whose main raw material is oil have also been limited.The total cotton production is still unable to meet the textile industry's needs.Wool,linen and other textile raw materials also need a lot of imports.In this situation, to explore a new cellulose fiber has practical significance. There are large area of sugarcane cultivation in China, and with higher yield. Sugarcane rind can be directly taken to use,and is rich in resources.As the bagasse has low density, low cost, and can be degraded, it is also been widely used for preparation of composite materials. Some studies showed that sugarcane rind fiber reinforced composite had better performance than the composites reinforced with bagasse fiber. As a result,based on the characteristics of sugarcane rind fiber, this paper studied on the extraction technology of sugarcane rind short fibers and fiber bundles.Short fibers can be used to prepare composite materials, fiber bundles can be used as textile fibers.First, this paper analyzed the sugarcane rind's components.The analysising results showed that the sugarcane rind contented about 35% cellulose, with the value of development and utilization.Then,for each component's proportion and different stability to acid-base, we selected the reasonable temperature and concentration of acid-base.This paper studied on the initial extraction process to extract sugarcane rind short fibers by means of the orthogonal test,combined with the fiber length and FTlR spectra.And it also analyze the main factors which impact the fiber's length.Was found the alkali boiling performance has greater impact to sugarcane rind fibers during the extraction process.So this paper has a further study on the effect of the alkali's boiling temperature, concentration and time to the sugarcane rind fiber's properties based on the initial exploration process.We obtained the optimum extraction technology by comprehensive analysis of sugarcane rind fiber's yield,length, crystallinity, mechanical properties, thermal properties.Finally,we tested the properties of the fiber obtained through the optimum extraction technology,such as the fiber's morphological structure, moisture absorption and desorption, density, and so on.By this means,we explore the feasibility of sugarcane rind fiber using in textile.
