Embodiment 1

[0013] Put hydrogen peroxide with a concentration of 50g / L, penetrant JFC (commercially available) with a concentration of 1g / L, and sodium tripolyphosphate with a concentration of 10g / L in water, stir evenly, and prepare a loose solution, and then mix the hemp of Apocynum The skin is immersed in the loosening solution, the bath ratio is 1:15 (weight ratio), the temperature is raised to 100°C, and the skin is kept warm for 40 minutes to loosen;

[0014] Then add 30g / L sodium hydroxide to the treatment bath after loosening, keep the temperature at 80°C for 60min to carry out refining and boiling;

[0015] The degummed apocynum bast fiber can be obtained by putting the boiled hemp bark into the prepared washing solution with pH 6, and washing at 75°C for 25 minutes.

Embodiment 2

[0017] Sodium hypochlorite that concentration is 30g / L, concentration is that 3g / L penetrant JFC (commercially available) and concentration are 5g / L sodium tripolyphosphate is placed in water, stir evenly, be mixed with loose solution, then the hemp of Apocynum The skin is immersed in the loosening solution, the bath ratio is 1:10 (weight ratio), the temperature is raised to 90°C, and the skin is kept warm for 50 minutes to loosen;

[0018] Add 15g / L potassium hydroxide to the treatment bath after loosening, heat at 85°C for 15min for refining;

[0019] Put the boiled hemp bark in the prepared washing liquid with pH 5, wash at 80°C for 15 minutes, and then obtain the degummed apocynum bast fiber.

Embodiment 3

[0021] The concentration is 55g / L hydrogen peroxide, concentration is 5g / L penetrant T (commercially available) and concentration is the sodium silicate of 8g / L and is placed in water, stirs evenly, is mixed with loose solution, then the hemp husk of Apocynum apocynum Immerse in the loosening solution, the bath ratio is 1:20 (weight ratio), heat up to 75°C, keep warm for 90min to loosen;

[0022] Then add 35g / L sodium hydroxide to the treatment bath after loosening, keep the temperature at 75°C for 80min for refining and boiling;

[0023] The degummed apocynum bast fiber can be obtained by placing the boiled hemp bark in the prepared washing liquid with pH 5.5 at a temperature of 75°C for 20 minutes.

Abstract

The invention relates to a short-process degumming method for apocynum bast fiber. The method comprises the following steps of: immersing apocynum skin in a decomposing liquid prepared from a decomposing agent, a penetrating agent and a chelating agent for decomposing, adding alkali in the decomposing liquid for stewing, then washing, and finally obtaining the apocynum bast fiber after degumming. The method has a short degumming process, saves the hemp-knocking working procedure in the traditional apocynum degumming technology, reduces labor intensity, shortens production time, increases working efficiency, reduces consumption of water, electricity and steam and sewage discharge, and benefits energy saving, emission reduction and cleaner production.

Description

technical field [0001] The invention relates to a short-process degumming method for apocynum bast fiber, in particular to a method for preparing apocynum bast fiber by using apocynum bast fiber as a textile raw material. Background technique [0002] The term "Apocynum" is a famous agricultural economist in my country, Mr. Dong Zhengjun, who discovered the use value of its fiber in Lop Nur, Xinjiang in the 1950s and named it. The apocynum he refers to is the general term for all plants of the genus Apocynum created by Linnai of the former Soviet Union. It belongs to the Apocynaceae family and is a perennial herbaceous plant. Its leaves can be used to make tea, medicine, and fiber is a raw material for high-end clothing. Have 3 kinds in my country, namely; Hemp, purple spot hemp, Poacynum pictum (Schrenk) Baill). Before the 1950s, apocynum was widely distributed in more than 10 provinces from northwest to northeast China. However, due to excessive logging, man-made destruc...
