Abstract

The invention discloses a preparation technology of a palm fiber; the preparation technology comprises the following steps: (1) acid dipping: putting a palm raw material into an acidic solution with the sulfuric acid concentration of 2-8 g/L, removing pigments on the surface of the fiber, and dissolving a part of pectin, wax and lignin impurities, wherein the acidic solution temperature during acid dipping is 40-60 DEG C and the time is 1-2 hours; (2) primary water washing; (3) primary alkali cooking: carrying out alkali cooking of a palm fiber after primary water washing, wherein the caustic soda amount during alkali cooking is 50-150 g/L, the time is 1.5-2 hours, and the temperature is controlled to be 90-140 DEG C; (4) secondary water washing; (5) chlorine bleaching; (6) pickling; (7) secondary alkali cooking; (8) tertiary water washing; (9) oxygen bleaching; (10) high temperature splitting; (11) quartus water washing; (12) vegetable oil addition and treatment; (13) finally, dehydration and drying treatment of the palm fiber after oil addition treatment. The prepared palm fiber has the advantages of soft hand feeling, high strength, strong moisture absorption and gas permeability, environmental protection, natural degradation and the like.

Description

technical field [0001] The invention relates to a fiber preparation process, in particular to a palm fiber preparation process. Background technique [0002] New health-care fibers are developing rapidly in our country at an extremely fast speed. Although some fibers still have imperfections in the development process, it is believed that with the continuous improvement and maturity of the production process, their performance will be improved. Its products have a very broad space for development; from the perspective of market consumption trends, people's pursuit of bedding functions has shifted from warm-keeping to health-care. [0003] Palm is a palm plant that grows widely in my country and is widely distributed in various provinces in the south of the Yangtze River. It is not only an excellent ornamental tree species, but also an important economic plant; palm fiber belongs to the sheath fiber of palm trees and has been used in people's production and life since ancient...
