Study on Degumming Technology and Properties of Pineapple Leaf Fiber

Abstract

This paper analyzes several existing pineapple leaf fiber degumming methods and their advantages and disadvantages and describes its relationship with the degumming from the structure characteristics and chemical properties of pineapple leaf fiber. The author puts forward the pineapple leaf fiber degumming technology should be to "high-quality, efficient, low consumption, low pollution" direction of development, and put forward a new method of degumming. By means of scanning electron microscope, infrared spectroscopy, mechanical properties, thermal gravimetric analysis, differential scanning calorimetry and other means, to study the structure, mechanical properties and thermal properties of pineapple leaf fiber biochemical degumming treatment. The results show that: biochemical degumming can take off the original fiber, fiber surface glue residue, single fiber are glial exist, but the fiber separation in good condition, the fiber surface is smooth; hemicellulose degradation in biochemical degumming process, but did not completely removed; no effect on biochemical degumming of pineapple leaf fiber structure has good effect, degumming the treated fiber; degumming relative strength; fiber still has relatively high heat resistance.
