Embodiment Construction

[0069] First of all, it is stated that the processing technology of the hemp bast fiber in the present invention is mainly explained by taking the processing of hemp as an example, but its application in the processing of other hemp bast fibers is not excluded.

[0070] The hemp class bast fiber processing technology provided by the invention comprises the following processing steps:

[0071] Unpack and sort the raw hemp husk, cut off the root and apex, perform mechanical degumming on the mechanical degumming equipment, put the bast fibers after mechanical degumming into cages, perform biological degumming and / or high-temperature cooking degumming, and then undergo high-temperature degumming After rinsing, the cage is unloaded, and after fiber separation, washing, rinsing, softness, and radio frequency drying, it is made into dry flax; then the lean flax is mechanically softened, oiled, infiltrated and maintained, and then sorted by stretching, needle combing, and combing. , A...

Abstract

The invention relates to a technological process of a ramie bast fiber, which comprises a basic degummed ramie production route: raw ramie skin-sorting and derooting-mechanical ungluing-cage loading-biological ungluing-high-temperature rinsing-cage unloading-sub-fiber washing-soft rinsing-radio frequency drying- degummed ramie. Long ramie can be growth through the mechanical hemp oiling- infiltration and health care-stretch breaking and carding-pre-gilling-combing and sorting-final gilling of the degummed ramie. Short ramie can be produced through the combing and the sorting of combed noil. Oakum can be produced through biological ungluing-high-temperature stewing and ungluing-high-temperature rinsing-cage unloading-sub-fiber washing-soft rinsing-dehydration and drying-radio frequency drying-mechanical hemp oiling- infiltration and health care-opening and edulcoration- combing and sorting. Improving methods are adopted for the mechanical ungluing, biological ungluing, high-temperature rinsing, sub-fiber washing, stretch breaking and carding, combing and sorting and the like. The preparation process has the advantages of short process, high production efficiency, high mechanical automation degree, stable product quality, excellent fiber quality and strong operability of fiber length and fineness, and can be used in the production processes of various bast fiber raw material, gramineae fiber raw material, leaf fiber raw material and other fibers.

Description

technical field [0001] The invention relates to a fiber processing technology, in particular to a processing technology of hemp bast fiber. Background technique [0002] my country is a big exporter of chemical fiber, cotton production, textile and clothing, and a major producer of textiles. In 2000, the output of synthetic fiber in my country exceeded 10 million tons, accounting for 70% of the total fiber, much higher than the international ratio of 60%. , The proportion of natural fibers and chemical fibers is out of balance. Since synthetic fibers produced from petroleum, coal, natural gas, etc. are raw materials, their resources are non-renewable and will eventually be exhausted. Therefore, renewable, recyclable, green and environmentally friendly renewable resources have attracted more and more attention. Since my country's reform and opening up, the supply of cotton has been in a state of shortage for more than 20 years. The history of my country's silk is mainly pro...
