Embodiment Construction

[0017] The invention provides a peeling process, in particular a process for producing pure bast fiber by using straw of fiber crops. The present invention uses a disc refiner to perform exfoliation at the base of the shorter fiber bundles. In describing the present invention, all terms not defined herein have their common art-recognized meanings. The following descriptions, of particular embodiments or particular uses of the invention, are in part illustrative only and not limiting of the invention as claimed. The following description is intended to cover all alternatives, modifications and equivalents as included within the spirit and scope of the invention as defined in the appended claims.

[0018] In this patent application, the following words have the following meanings:

[0019] "Bast" refers to the fibers of the phloem or inner bark of the plant in fiber crops.

[0020] "Decortication" refers to the process of separating the bast of a plant from the inner core.

Abstract

A process of decortication for separating the bast from the inner core of fibre plants using a disc refiner includes the steps of cutting the straw to a predetermined length; refining the straw by passing the cut straw of the predetermined length through a disc refiner with an applied energy less than about 150 kWh / t; and screening the refined straw to separate the bast fibres from the inner core.

Description

technical field [0001] The invention relates to a decortications process, in particular to a process for producing pure bast fibers from fiber crop stalks. Background technique [0002] Bast fibers obtained from dicotyledonous plants such as jute, hemp, ramie or kenaf have various commercial uses. Typically, bast fibers have been utilized by the textile industry to produce fabric products such as carpet yarns, ropes, geotextiles, traditional burlap and jute scrims. However, bast fibers are increasingly used in other industries such as the manufacture of nonwoven blankets and carpets, composites, and automotive interior panels. Cellulose-based industries recover cellulose from bast for pulp and paper products. [0003] Before the bast fibers can be used, the bast fibers of the fiber plant must first be separated from the inner core by some form of stripping process. There are various stripping processes in the prior art, but generally, automatic machinery is used to subjec...
