Problems solved by technology

Although pickling is used, because the pertinence is not strong, iron ions still exist after the flax roving is degummed and bleached, so it still has the above-mentioned defects

Embodiment Construction

[0022] The present invention will be described in further detail below through examples, and the following examples are explanations of the present invention and the present invention is not limited to the following examples.

[0023] Example.

[0024] Taking L36Nm as an example, the bath ratio is 1:10, and the iron removal process of flax roving is applied in the flax yarn spinning process. The specific process is as follows.

[0025] (1) Iron removal: The flax roving is treated to remove iron ions, and the iron ions in the hemp fiber are removed. The scouring agent F-MFB with a concentration of 0.5g / L and the extractant RED with a concentration of 0.5g / L are used. , Use the extractant EX with a concentration of 1.5g / L and 96% acetic acid with a concentration of 0.5g / L, adjust the pH to 5.0-5.5, and treat at 70°C for 20 minutes.

[0026] (2) Washing: Wash with water at room temperature for 10 minutes.

[0027] (3) Degumming and bleaching: degumming and bleaching the roving....

Abstract

The invention relates to an iron removing process for flax roving and belongs to the technical field of flax processing. The iron removing process includes: iron ion removing is performed on the flax roving to remove iron ions in hemp fibers, then normal degumming and bleaching are performed on the roving, and finally the roving is washed. The iron removing process has the advantages that the iron removing is performed before the oxygen bleaching, hydrogen peroxide is prevented from being catalyzed by iron, the strength of the roving is increased effectively, the reaction during the oxygen bleaching is stable and even, and damage to fibers is small.

Description

technical field [0001] The invention relates to a new iron removal process for flax roving, which can effectively improve the quality of flax yarn. It is a process for removing iron from flax roving first, followed by a normal degumming and bleaching process, and is mainly used in the spinning process of flax yarn. production, which belongs to the technical field of flax treatment. Background technique [0002] During the growth process of flax, while absorbing nutrients from the soil and water, it also absorbs a large amount of heavy metals, which affects the quality and processing technology of flax, especially iron ions, if not removed, during the hydrogen peroxide bleaching process It will cause local damage to the fiber; because iron ions have a catalytic effect on the hydrogen peroxide reaction, the hydrogen peroxide in the iron-containing place in the flax reacts violently and oxidizes the cellulose, resulting in strong fiber damage. [0003] Although pickling is use...
