Embodiment 1

[0039] The processing method of wet spinning pure flax knitting yarn, comprises the following steps:

[0040] ①Bundle splitting: Excision of 5-10cm from the tip of the softer tip and more hemp particles, and then splitting;

[0041] ② Blending of flax: 6 kinds of flax with different properties and different origins are used in the slitting machine and pre-combination to comb into flax for matching;

[0042] ③ Roving: The twist coefficient of the roving is set to 0.25T / cm, and the winding density of the roving is set to 0.35g / cm 3 , the workshop temperature is 25°C, and the relative humidity is 75%;

[0043] ④ Roving degumming and bleaching: the process adopts the silicon-free hydrogen peroxide bleaching process, the details are as follows:

[0044] a) Pretreatment process: scouring enzyme: 2g / l, scouring agent: 0.5g / l, NaOH: 2g / l, NaOH: 2g / l, 2 CO 3 : 3g / l, temperature 55°C, treatment time 60min;

[0045] b) Wash with water at room temperature for 15 minutes;

[0046] c)...

Embodiment 2

[0054] 1) Yarn linear density: 26Nm;

[0055] 2) Bundle splitting: cut off the tip of the hemp that is relatively soft and has more hemp particles by 5 cm, and then split the beam;

[0056] 3) Flax blending: use multi-variety raw materials for flax blending in the slitting machine and pre-combination, use 5 different types of French 26Nm flax and 7 different types of Belgian 26Nm flax for use;

[0057] 4) Roving: The twist coefficient of the roving is set to 0.23T / cm, and the winding density of the roving is set to 0.37g / cm 3 , the workshop temperature is 20-30°C, and the relative humidity is 70%-80%;

[0058] 5), roving degumming and bleaching: the process adopts the silicon-free double oxygen bleaching process; the process flow: pre-treatment - water washing - the first silicon-free bleaching - water washing - the second silicon-free bleaching - washing clean - - Post-processing. Concrete process implementation: a) pretreatment process: scouring enzyme: 2.5g / l, scouring a...

Embodiment 3

[0064] 1) Yarn linear density: 28Nm;

[0065] 2) Bundle splitting: cut off the tip of the hemp that is softer at the tip and has more hemp particles by 8cm, and then split it;

[0066] 3) Blending flax: use multi-variety raw materials to blend flax on the slitting machine and pre-combination, use 4 different types of French 28Nm flax and 4 different types of Belgian 28Nm flax for use;

[0067] 4) Roving: The twist coefficient of the roving is set to 0.24T / cm, and the winding density of the roving is set to 0.37g / cm 3 , the workshop temperature is 20-30°C, and the relative humidity is 70%-80%;

[0068] 5), roving degumming and bleaching: the process adopts the silicon-free double oxygen bleaching process; the process flow: pretreatment - water washing - the first silicon-free bleaching - water washing - the second silicon-free bleaching - washing clean - —Post-treatment; specific process implementation: a) pre-treatment process: scouring enzyme: 2.0g / l, scouring agent: 1g / l, ...

Abstract

The invention relates to a method for processing knitting yarn by flax, in particular to a method for processing wet spinning pure flax knitting yarn, which belongs to the technical field of flax spinning. The method for processing the wet spinning pure flax knitting yarn comprises the following steps: (1), bundle separation; (2), flax matching; (3), roving; (4) roving degumming and bleaching; (5), wet spinning; and (6), winding. The method aims to overcome technical difficulties in the processes of raw material selection of flax and the roving degumming and bleaching. To overcome the technical difficulties, various kinds of raw materials from multiple producing areas are matched according to the method, so that the advantages and defects of the raw materials are complemented. A boiling-bleaching technology utilizes bioenzyme to damage an adhesion substance in fiber and then adopts secondary hydrogen peroxide to bleach; damage to the fibres is reduced; the bleaching technology adopts silica-free stabilizing agent to reduce hardening and roughening of the yarn, which are caused by that silica scale deposits in the yarn; and the rigidity of the flax is changed by jointly adopting a softener and lubricant after treatment.

Description

technical field [0001] The invention relates to a method for making knitting yarn from flax, in particular to a processing method of wet spinning pure flax knitting yarn, which belongs to the technical field of flax spinning. Background technique [0002] Flax fiber is a rare natural fiber, accounting for only 1.5% of the total natural fiber. It has the functions of moisture absorption and heat dissipation, health care and antibacterial, anti-fouling, anti-static, anti-ultraviolet, etc., and has excellent flame retardant effect. But at the same time it has a rough appearance and a stiff feel. How to make full use of strengths and circumvent weaknesses to weave flax fibers into linen fabrics with delicate touch and comfortable wear has become the goal that experts in this field strive to overcome. Although linen woven fabrics have a history of thousands of years, at least so far, no matter how to adjust the production process, or the reasonable use of various additives such...
