Abstract

The invention discloses a processing technology of fibrilia for seedling base cloth, andthe processing technology flow is as follows: after mechanically and repeatedly rolling of the raw hemp, the fine fibrilia is obtained by facilitating pre-soaking, boiling, softening, dewatering and drying and mechanical post-treatment. The processing method realizes good degumming effect by using three flow steps of mechanical pretreatment, pre-leaching and boiling off, in particular to the degumming treatment of the fibrilia by using an acid-base coordination compound enzyme, the residual gum rate is low,the process flow is simple, and the fine fibers are favorably obtained. By using the softening and mechanical post-processing, the fine fibrilia is further obtained through slow carding, the strengthof the fibrilia is reduced, and the fiber is uniformly distributed, so that the prepared seedling base cloth has stable quality, and the mechanical property can well meet the requirement of seedlingraising and seedling cultivation.

Description

technical field [0001] The invention relates to a processing technology of hemp fiber, in particular to a processing technology of hemp fiber for seedling raising base cloth. Background technique [0002] Hemp fiber is a fiber obtained from various hemp plants, including the bast fiber of the cortex of annual or perennial herbaceous dicotyledonous plants and the leaf fiber of monocotyledonous plants. Because of its high strength, high rigidity, and good functions of moisture absorption, moisture dissipation and ventilation, it is widely used in various textiles, daily necessities and agricultural production. In particular, with the continuous development of agricultural production and the improvement of the quality of agricultural products, the technical requirements for hemp fibers used in agricultural production such as seedling raising, lawn sowing modeling, and agricultural product coverage are getting higher and higher. [0003] The main component of hemp fiber is cell...
