Problems solved by technology

Chinese patent ZL95117638.2 discloses a kind of mulberry bark fiber and its preparation method and application. As mentioned in the article, mulberry trees are planted in a large area in my country, but the purpose of planting mulberry trees is to provide mulberry leaves for sericulture, not to provide wood , so it is impossible for the market to provide a large amount of low-priced mulberry bark for fiber production

Embodiment 1

[0025] Take the elm tree that has just been felled, remove the old bark on the surface of the tree by hand, and then separate the bast layer from the tree stem. Try to avoid bringing in the hard wood fiber layer in the tree stem, and classify it according to the size of the bast bark of the tree. The tree bast with substantially the same size is put into a pool of 12g / L sodium hydroxide concentration, 0.5% by weight washing powder, and a temperature of 60°C. After soaking for 12 hours, take it out and dry it. After evenly spraying the emulsion in the humidification chamber, cover it with a cloth for 18 hours of health preservation; put the health care treatment into a mixture containing 1.5% of Remy Bang A, 0.5% of JFC, 1% of palm oil, 1% of motor oil and water 1:20 The tanning agent is used for tanning, and the tanned bast fiber is cut into about 70mm, opened and fiberized by a cotton opener, put into a carding machine for 3 to 5 times of carding, and the carded fiber is colle...

Embodiment 2

[0027] Get freshly felled willow branches, separate the bark from the stems by hand, put the sodium hydroxide concentration at 3g / L, add washing powder with 1% by weight, and soak in a pool at 20°C for 48 hours Finally, take it out and dry it, put it into the humidification chamber, spray the emulsion evenly, and cover it with a cloth for 24 hours of health preservation; put the bast fiber after the health care treatment into the water containing the following weight percentages: 2% penetrant M, 1% JFC , 1% peanut oil, 1% engine oil in normal temperature water for tanning, the bast fibers after tanning are cut into about 70mm, opened and fibered with a cotton opener, placed in a carding machine for 3 to 5 times, collected and carded The finished fibers were dried in an oven and then separated into bast fibers of different specifications by an airflow classification box. The properties of the fibers are shown in Table 1.

Embodiment 3

[0029] Get the oleander just felled, bark is separated from bark by hand, and bark is put into sodium hydroxide concentration and is 8g / L, adds the washing powder of 1% weight part, and temperature is in the pool of 50 ℃, After soaking for 24 hours, take it out and dry it, put it into the humidification chamber, spray the emulsion evenly, and then cover it with cloth for 24 hours; put the bast fiber after the health treatment into the water containing the following weight percentage: 1% Remybang A. Soak and tan with 1% Pingpingjia, 1% JFC, 1% vegetable oil, and 1% machine oil in water at 40°C, cut the bast fiber after tanning into about 70mm, open it with a cotton opener, and put it into carding Carding is carried out in the machine for 3 to 5 times, and the combed fibers are collected and dried in an oven, and then separated into bast fibers of different specifications through an airflow classification box. The fiber properties are shown in Table 1.

Abstract

The present invention discloses a kind of tree bast fiber and its method for processing, wherein the fiber is a natural spinning fiber made of bark from the trees except mulberry and paper mulberry with its length of 5mm-65mm, the fineness of 0.3-2.5D, the strength of 0284-0432N / tex and the extensibility at break of 3%--7%. The processing method is as follows:peeling-sorting-degumming-skimming-drying-preserving-tanning-grinding-combing-baking-boxing and classifying-baling. The invention provides a kind of basic spinning fiber for textile industry, which has cheap and wide sources of tree bast, the similar performance of jute fiber, stronger strength than that of cotton fiber and good dyeing ability with wide use prospect, and can be co-spinned with other natural fibers, staple fiber or regenerated fiber into fiber yarns.

Description

technical field [0001] The invention relates to a textile fiber, in particular to a tree bast fiber, and also relates to a processing method of the fiber. Background technique [0002] Wood is a natural resource, which is of great significance to the survival and development of human beings. Wood has a wide range of applications and is closely related to people's lives. At present, people's application of trees generally uses the lignin part of trees, and the bark is Generally treated as waste, how can it be effectively used to improve the utilization value of trees and turn waste into treasure. Chinese patent ZL95117638.2 discloses a kind of mulberry bark fiber and its preparation method and application. As mentioned in the article, mulberry trees are planted in a large area in my country, but the purpose of planting mulberry trees is to provide mulberry leaves for sericulture, not to provide wood Therefore, it is impossible for the market to provide a large amount of low-p...
