Embodiment 1

[0032] The process of extracting the vine fiber of the present invention adopts the following steps:

[0033] a. Arrange and cut off the stems of the rattan to about 1 meter in length, and tie them into small bundles, 30 to 50 in each bundle;

[0034] b. Soak the bundle-shaped rattan stalks in water at a temperature of 20°C for 30 days;

[0035] c, take it out from the water, and scald for 1 hour in a caustic soda solution with a mass concentration of 1%, the bath ratio is 1:4, and the temperature is 100°C;

[0036] d, peeling after washing in cold water, so that the bast is separated from the stem, the xylem of the stem is removed, and the bast part is retained;

[0037] e, the phloem part is soaked for 30 minutes with a mass concentration of 0.1% sulfuric acid solution, and the temperature is room temperature;

[0038] f. Wash with water or soap at room temperature to remove part of the hard skin and glue;

[0039] g. Scouring for 1 hour with caustic soda or ammonium oxal...

Embodiment 2

[0046] The process of extracting the vine fiber of the present invention adopts the following steps:

[0047] a. Arrange and cut off the stalks of the rattan rattan to a length of about 1 meter, and tie them into small bundles, 30 in each bundle;

[0048] b. Soaking the bundle-shaped rattan stalks in water at a temperature of 15°C for 35 days;

[0049] c, take it out from the water, and scald for 1.5 hours in a caustic soda solution with a mass concentration of 0.5%, the bath ratio is 1:5, and the temperature is 110°C;

[0050] d, peeling after washing in cold water, so that the bast is separated from the stem, the xylem of the stem is removed, and the bast part is retained;

[0051] e, the phloem part is soaked for 35 minutes with a mass concentration of 0.05% sulfuric acid solution, and the temperature is room temperature;

[0052] f. Wash with water or soap at room temperature to remove part of the hard skin and glue;

[0053] g. Scouring for 1.5 hours with caustic soda ...

Embodiment 3

[0059] The process of extracting the vine fiber of the present invention adopts the following steps:

[0060] a. Arrange and cut off the stalks of the rattan rattan into a length of about 1 meter, and tie them into small bundles, 50 in each bundle;

[0061] b. Soaking the bundle-shaped rattan stalks in water at a temperature of 25°C for 26 days;

[0062] c, take it out from the water, and scour it for 0.5 hour in a caustic soda solution with a mass concentration of 1.5%, the bath ratio is 1:3, and the temperature is 90°C;

[0063] d, peeling after washing in cold water, so that the bast is separated from the stem, the xylem of the stem is removed, and the bast part is retained;

[0064] e, the phloem part is soaked for 25 minutes with a mass concentration of 0.15% sulfuric acid solution, and the temperature is room temperature;

[0065] f. Wash with water or soap at room temperature to remove part of the hard skin and glue;

Abstract

The invention relates to a paederia scandens fiber extraction process which includes that the paederia scandens stems are tidied, cut and bundled, and impregnated in water, and then the paederia scandens stems are taken out from water and scoured, the stems are peeled after being washed in cold water and the bast is maintained, than the peeled stems are washed through water or soaping, and embathed in sulfuric acid solution; and then the stems are scoured in caustic soda or ammonium oxalate solution in which sodium silicate with mass concentration of 1-2% and STPP with mass concentration of 1-2% are added, and then the stems are washed through water or soaping; subsequently, the stems are embathed in sulfuric acid solution, is washed through water or soaping, is dehydrated and fluffed, and is finally dried under the constant temperature of 100-120 DEG C. the invention has the advantages that: the source of feed is wide, the development cost is low, the application of the fiber is broad, the fiber and textile not only can be applicable to spinning and clothing industry, but also can be applicable to medical operation suture lines and hemostatic gauze in medical and sanitation field, also have superior advantages comparing with common fibers, and have higher practicality.

Description

technical field [0001] The invention relates to a method for extracting natural fibers, in particular to a process for extracting vine fiber. Background technique [0002] There are many fiber substances in nature, but the natural fibers used as textile materials for the production of yarns and fabrics are limited after all. Fibers that can be used for spinning and weaving must have certain properties, with a fineness in the range of 0.1dtex to 50dtex, a length of more than 5mm, and a strength of more than 0.5cN / dtex. [0003] Fibers used in textiles are divided into two categories: natural fibers and chemical fibers. Natural fibers are divided into plant fibers and animal fibers. Plant fibers are mainly obtained by cultivating cotton and hemp; animal fibers are mainly obtained by raising sheep and silkworms. Most of the chemical fibers are obtained by chemical synthesis relying on petroleum resources. After all, these natural fiber or chemical fiber resources are limite...
