Description

Technical Field

[0001] The utility model relates to the technical field of hemp fiber, in particular to an air drying device for preparing hemp fiber. Background Technique

[0002] Hemp, also known as cannabis, is an annual erect herbaceous plant of the Cannabaceae family and the Cannabis genus. The fiber of the hemp stem bark is long and tough. Among many types of hemp, hemp is particularly precious. The fiber of hemp is very soft and has extremely high toughness. The top is blunt and round, unlike ramie and flax which are sharp. The fabric woven from it is delicate and white, with a fineness only one-third of that of ramie, and it has no itchy feeling and roughness of other hemp textiles. Clothes made of hemp fiber can be as light as smoke like silk and are softer and more comfortable than cotton-padded clothes. Therefore, it is widely used in the textile industry.

[0003] In the process of hemp processing, multiple processing steps are required. One of them is to wash the prepared hemp fiber. After washing, it needs to be air-dried. However, during the air-drying process of the fiber, because the cold air blows directly on the hemp fiber hairs, the fiber hairs may be easily blown apart during air-drying, and the air-dried finished product is relatively messy, which is likely to affect the output quality of the fiber and requires manual secondary treatment, making the operation rather troublesome and inconvenient. Therefore, in view of the above problems, we have developed a new air drying device for preparing hemp fiber. Content of the Utility Model
