Embodiment 1

[0026] (1) Sorting and root cutting: Take Polygonum multiflorum vine samples, sort them, remove the unseparated Polygonum multiflorum roots, leaves, seeds and gravel and other sundries, tidy the Polygonum multiflorum vines, and remove the roots 20cm away from the roots. The lower part of the main vine was cut off.

[0027] (2) Soaking: Soak the Polygonum multiflorum vine after the above treatment in a constant temperature (90°C) water bath for 2 hours.

[0028] (3) Peeling: the skin-core separation method is used to peel off the bast layer of Polygonum multiflorum. Note that the moisture content of the sample to be stripped should be moderate, if it is too low, it cannot be stripped smoothly, and if it is too high, the phloem layer will easily break, thereby destroying the integrity of the fiber.

[0029] (4) Pre-oxygenation: Pre-oxidize the bast of Polygonum multiflorum vine after treatment in (1), (2) and (3), bath ratio 1:20, pre-oxygenation temperature 50°C, time 2h, H 2...

Embodiment 2

[0040] (1) Sorting and root cutting: Take Polygonum multiflorum vine samples, sort them, remove the unseparated Polygonum multiflorum roots, leaves, seeds and gravel and other sundries, tidy the Polygonum multiflorum vines, and remove the roots 20cm away from the roots. The lower part of the main vine was cut off.

[0041] (2) Soaking: Soak the Polygonum multiflorum vine after the above treatment in a constant temperature (90°C) water bath for 2 hours.

[0042] (3) Peeling: the skin-core separation method is used to peel off the bast layer of Polygonum multiflorum. Note that the moisture content of the sample to be stripped should be moderate, if it is too low, it cannot be stripped smoothly, and if it is too high, the phloem layer will easily break, thereby destroying the integrity of the fiber.

[0043] (4) Pre-oxygenation: Pre-oxidize the bast of Polygonum multiflorum vine after treatment in (1), (2) and (3), bath ratio 1:20, pre-oxygenation temperature 50°C, time 2h, H 2...

Embodiment 3

[0054] (1) Sorting and root cutting: Take Polygonum multiflorum vine samples, sort them, remove the unseparated Polygonum multiflorum roots, leaves, seeds and gravel and other sundries, tidy the Polygonum multiflorum vines, and remove the roots 20cm away from the roots. The lower part of the main vine was cut off.

[0055] (2) Soaking: Soak the Polygonum multiflorum vine after the above treatment in a constant temperature (50°C) water bath for 3 hours.

[0056] (3) Peeling: the skin-core separation method is used to peel off the bast layer of Polygonum multiflorum. Note that the moisture content of the sample to be stripped should be moderate, if it is too low, it cannot be stripped smoothly, and if it is too high, the phloem layer will easily break, thereby destroying the integrity of the fiber.

[0057] (4) Pre-oxygenation: Pre-oxidize the bast of Polygonum multiflorum vine after treatment in (1), (2) and (3), bath ratio 1:20, pre-oxygenation temperature 50°C, time 2h, H 2...

Abstract

The invention relates to a preparation method of polygonum multiflorum fiber used for spinning. The preparation method comprises the steps of: (1) taking polygonum multiflorum fiber rattan samples, sorting and cutting roots and then soaking with water bath, and finally stripping a bast layer of polygonum multiflorum fiber rattan by adopting a bast-core separating method; and (2) carrying out pre-oxidation, washing, soda boiling, hydraulic power washing, oil feeding after dehydrating, removing oil water, fluffing and drying on the stripped bast of the polygonum multiflorum fiber rattan so as to obtain the polygonum multiflorum fiber. According to the preparation method provided by the invention, the process is simple, the equipment requirement is low, the usage amount of chemical medicine is few and the production cost is low, and industrial popularization is facilitated, the polygonum multiflorum is utilized, so that waste material is changed into things of value, resource is saved, and the environment is protected; and the polygonum multiflorum fiber prepared by adopting the preparation method provided by the invention has good flexibility and spinning processability and can meet requirements of people to environment-friendly and ecological comfort pure fibers.

Description

technical field [0001] The invention belongs to the field of preparation methods of fibers for textiles, in particular to a preparation method of Polygonum multiflorum fibers for textiles. Background technique [0002] Polygonum multiflorum, a Chinese herbal medicine, belongs to Polygonaceae and is a perennial deciduous vine medicinal plant. The stems are hollow, with many branches, and the stems more than 2 years old have different degrees of lignification; the stems touch the ground, and the nodes are easy to root, and can grow into independent plants. The root is slender, and the end becomes a hypertrophic root tuber, and the appearance is reddish brown to dark brown. "Ben Cao Tu Jing": "The Chinese herbal medicine Polygonum multiflorum is found everywhere today. The ones in Songshan Mountain in Xiluo and Zhecheng County in Nanjing are the best. The spring-growing seedlings and leaves are relatively like a potato and not shiny. The stems spread between bamboo and wood wa...
