Problems solved by technology

[0002] Felt is widely used in automobile interior decoration. When the felt produced by the existing felt processing manufacturers is processed, the hemp fiber is easily broken during the acupuncture step, especially the felt products made of fine hemp. Due to its high tensile strength, it is easy to break, the surface is rough, and the texture is poor. However, the dry hemp has a layering performance that other natura

Embodiment Construction

[0015] The steps of the manufacturing method of the present invention are as follows: the fine-dried hemp is firstly subjected to degumming treatment, and the processed refined-dried hemp and Mongolian hemp fibers are mixed according to a mass ratio of 1:1 and added to an opener, and after being opened for 30 minutes, they are poured into a cotton mixing box for refining. Opening treatment, the finely opened raw cotton material is fed into the cotton box by air pressure and poured into the carding machine. The carding machine entangles the fibers of the raw cotton material in the forward direction into a mesh felt board. After forming a web, take the tray and put the mesh felt The board is placed on the tray, and the surface is sprayed with a special fiber softening agent. The amount of fiber softening agent is immersed in the mesh felt board, soaked for 1 hour, and dried in a drying oven. When the fluffiness of the mesh felt board reaches 450, stop drying , using acupuncture e...

Abstract

The invention discloses a method for manufacturing a non-woven refined dry flax punched felt. The situation is effectively improved that an existing refined dry flax punched felt is easy to break in needling operation, multiple degumming treatment and softening treatment are adopted, and the breakthrough of the performance of existing refined dry flax punched felts in the market is realized.

Description

technical field [0001] The invention relates to the field of felt processing, in particular to a method for manufacturing a non-woven refined hemp needle-punched felt. Background technique [0002] Felt is widely used in automobile interior decoration. When the felt produced by the existing felt processing manufacturers is processed, the hemp fiber is easily broken during the acupuncture step, especially the felt products made of fine hemp. Due to its high tensile strength, it is easy to break, the surface is rough, and the texture is poor. However, the dry hemp has a layering performance that other natural hemp fibers cannot match. There are many types of felt that can be processed and shaped, and the quality is lighter than other natural hemp fibers. Moreover, the planting amount of raw materials is large and the cost is low. In the existing felt production, it is not possible to make up for the defects of the fine-dried hemp and at the same time give full play to its grea...
