Embodiment 1

[0023] Such as figure 2 Shown, the tree bast fiber nonwoven fabric of the present invention is made of the tree bast fiber 1 of 100% by weight, and the length of the tree bast fiber 1 is 15~40mm, fineness 0.5~1.5D; The skin fibers 1 are evenly mixed with each other, interspersed and interwoven to form a three-dimensional net-like braided structure. The specific processing methods of non-woven fabrics are as follows:

[0024] (1) Tree bast fiber processing: the freshly felled spruce trees are processed by peeling → sorting → degumming → removing slag and impurities → drying → health preservation → tanning → crushed stems → combing → drying → boxing and grading. Tree bast fiber 1 with a length of 15-40mm and a fineness of 0.5-1.5D.

[0025] (2) Compounding: 5% talcum powder is mixed into the bast fiber 1, and the traditional compounding machine is used to carry out two compoundings.

[0026] (3) Carding: carding carried out according to the existing traditional cotton spinni...

Embodiment 2

[0030] Such as image 3 Shown in, the tree bast fiber nonwoven fabric of the present invention is made up of the tree bast fiber 1 of 70% weight part and the ramie fiber 2 of 30% weight part, and the length of tree bast fiber 1 is 10~35mm, The fineness is 0.3-2D; the length of the ramie fiber 2 is 5mm-45mm, and the fineness is 0.3D-2.5D. Tree bast fibers 1, ramie fibers 2, and tree bast fibers 1 and ramie fibers 2 interpenetrate and interweave to form a three-dimensional net-like weaving structure; a nylon net-like bottom is also provided under the non-woven fabric. cloth3. The specific processing methods of non-woven fabrics are as follows:

[0031] (1) Tree bast fiber processing: the newly felled banyan tree branches are peeled → sorted → degummed → slag and impurity removed → dried → health → tanning → broken stems → combing → drying → binning and grading to form lengths Tree bast fiber 10-35mm, fineness 0.3-2D.

[0032] (2) Compounding: 70% of the tree bast fiber 1 was...

Embodiment 3

[0037] Such as Figure 4 As shown, the tree bast fiber nonwoven fabric adopts 50% by weight of tree bast fiber 1 and 50% by weight of cotton fiber 2. The length of tree bast fiber 1 is 20-40mm, and the fineness is 1.5D-2.5 D; Tree bast fibers 1, cotton fibers 2, and tree bast fibers 1 and cotton fibers 2 interweave and interweave to form a three-dimensional network weaving structure; on the upper surface, middle and The lower surface is also provided with three layers of nylon mesh base cloth 3 . The specific processing methods of non-woven fabrics are as follows:

[0038] (1) Tree bast fiber processing: the freshly felled oleander is processed by peeling→sorting→degumming→removing slag and impurities→drying→health→tanning→broken stems→combing→drying→boxing and grading. Tree bast fiber 1 with a length of 20-40mm and a fineness of 1.5-2.5D.

[0039] (2) Mixing: After mixing 50% of the tree bast fiber 1 with 3% talcum powder and 50% by weight of the cotton fiber 2, the tradit...

Abstract

This invention discloses non-woven fabric of tee bast fiber and its process method, among which, the non-woven fabric is composed of 1-100% weight proportion of tree bast fibers and 0-99% other spinning fiber, fibers are mixedly woven among tree bast fibers, the spinning fibers, the bast and spinning fibers to form a cubic net woven structure including the following steps: process tree base fibres, mixing, combing, spreading the net and transfixation.

Description

technical field [0001] The invention relates to a non-woven fabric, in particular to a tree bast fiber non-woven fabric which can be used to produce various disposable protective articles, and also relates to a processing method of the non-woven fabric. 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...
