Abstract

The invention discloses a preparation method of raw bamboo fiber needled-punched felt. The raw bamboo fiber needled-punched felt is prepared by 30-95wt% of raw bamboo fiber and 5-70wt% of chemical fiber through opening, mixing, carding, lapping, needling, hot rolling and sizing procedures in sequence, wherein the carding procedure includes: the opened and mixed raw bamboo fiber and chemical fiber are fed into a carding machine for carding, so as to form a fiber web, the feeding line speed is 0.5-1.5m / min, the feeding fiber amount is 2-4kg / m, the main cylinder frequency of the carding machine is 400-800rpm / min, and the room temperature in the carding procedure is controlled to be 15-28 DEG C and relative humidity is controlled to be 60-90%, so as to effectively prevent raw bamboo fiber smash and breakage, thus solving the problems that the raw bamboo fiber is difficult to card and the formed web is not even in the prior art. By the method of the invention, the raw bamboo fiber needled-punched felt with evenly formed web, smooth surface, good antibacterial action and air permeability, and strong absorbability can be prepared.

Description

technical field [0001] The invention relates to the field of nonwoven fabric manufacture, in particular to a method for making bamboo fiber needle felt. Background technique [0002] Needle-punched felts manufactured by needle-punching technology in the non-woven field were mainly used in the field of flue gas dust removal in the past. In recent years, with the continuous development of the application of non-woven acupuncture technology, its application in the field of home textiles is also very extensive, such as interior decoration, clothing liners, shoemaking, etc. Its structure is mainly based on single-layer fiber structure , and form needle-punched felts or boards of different weights and thicknesses. The fibers used are usually chemical fibers, which have poor antibacterial properties, air permeability and moisture absorption properties. [0003] Bamboo fiber has excellent antibacterial properties, air permeability and hygroscopicity. Currently, the fibers made from...
