Abstract

The invention relates to a processing technology of bamboo fibers for a seedling culture base fabric. A flow of the processing technology comprises the following steps: after mechanically and repeatedly rolling bamboo wood; carrying out pre-impregnation, scouring, softening, dehydration and drying, and mechanical post-treatment to obtain fine bamboo fibers. According to the processing technology provided by the invention, a good degumming effect is realized by utilizing three flow steps including mechanical pre-treatment, the pre-impregnation and the scouring; especially, scouring liquid prepared by matching acid and alkali with a complex enzyme is used for carrying out degumming treatment on the bamboo fibers; the residual gum rate is relatively low and a technological flow is simple; relatively fine fibers are easy to obtain. Softening and mechanical post-treatment are utilized; furthermore, the fine bamboo fibers are obtained through slow-speed carding, the strength of the bamboo fibers is reduced and the fibers are uniformly distributed, so that the prepared seedling culture base fabric has stable quality and the mechanical properties can meet the utilization requirements of seedling culture and rice seedlings culture very well.

Description

technical field [0001] The invention relates to a processing technology of bamboo fiber, in particular to a processing technology of bamboo fiber for seedling raising base cloth. Background technique [0002] Bamboo fiber is a fiber obtained from various bamboo plants, including the bast fiber of the cortex of annual or perennial herbaceous dicotyledonous plants and the leaf fiber of monocotyledonous plants. [0003] The main component of bamboo fiber is cellulose, followed by hemicellulose, pectin and lignin. The outside of bamboo fiber is covered with gum, which makes the fibers glued to each other. It cannot be directly used to prepare the desired product. Therefore, it must be degummed to release the fiber and be in a separated state. Traditional bamboo fiber degumming mainly involves chemical degumming with caustic soda, using strong acid, strong alkali, high temperature and high pressure cooking, to break the fiber molecular chain and improve the crystallinity, but af...
