Abstract

Available flax staple treating method, mainly including mechanical process and glue-eliminating alkali boiling-off process, has no obvious effect on improving spinnability. The technological scheme of the present invention is a chemical treatment technology with scouring and bleaching as main features, and the flax staple treated by the said technological process has greatly improved spinability and is used as material for producing high-grade and high-count flax yarn.

Description

A kind of rescutched tow chemical treatment technology
The invention belongs to flax raw material treatment process technical field, particularly belong to rescutched tow chemical treatment technology field.
At present, domestic factory with the second hards spinning, in order to improve the second hards spinnability, second hards is carried out preliminary treatment, general processing method has two kinds: a kind of after to be machining process to second hards carry out shredding, removal of impurities, divide, make flax cotton, spin, as application number is 92112539 inventions, this processing technology produces a large amount of dusts, work under bad environment, it is healthy directly to endanger the workman, and flax spinnability that machining is crossed is improved little, can only carry out blending with fiber such as cotton, pure spinning is stranded dimension very much; A kind of is the NaOH alkaline-heating method: as application number is that 93100748 inventive methods are only carried out kiering with NaOH and come unstuck, and the second hards spinnability that adopts this method to handle is improved little.
The objective of the invention is the deficiency at machining and soda boiling degumming method processing second hards technology, develop a kind of chemical treatment technology, the second hards the key technical indexes after the processing can be effectively controlled and improve, and improves its spinning property greatly.
Technical scheme of the present invention is with chemical method rescutched tow to be handled, and under bath raio was 1: 15 condition, its process was:
Water logging → kiering → washing → bleaching → washing, detailed process is:
(1) water logging: normal temperature water logging 10min,
(2) kiering: 1. NaOH 6.0～10.0g/l
②Na 2CO 3 1.0～3.0g/l
③Na 2S 2O 4 1.0～4.0g/l
4. bleeding agent (fatty alcohol-polyoxyethylene ether) 0.1～0.3g/l
1. 2. 4. water heat temperature raising to 50 ℃ adds, and rises to 70 ℃ of addings 3. by 50 ℃, continues to be warming up to 95 ℃, insulation 50～70min,
(3) washing: normal-temperature water is washed till neutrality
(4) bleaching: 5. hydrogen peroxide stabilizer 2.0～4.0g/l
⑥Na 2CO 3 1.0～3.0g/l
7. bleeding agent (fatty alcohol-polyoxyethylene ether) 0.1～0.3g/l
⑧H 2O 2(100％) 1.0～4.0g/l
8. 5. 6. 7. ℃ adding of water heat temperature raising to 50 be warming up to 70 ℃ of addings, continues to be warming up to 95 ℃, behind the insulation 40min, and the 20～30min that lowers the temperature naturally,
(5) washing: normal-temperature water is washed till neutrality,
Above-mentioned steps (1), (3), (5) are preamble, and (2), (4) are characteristic.
The advantage that the present invention had:
1, selected reagent is nontoxic, and is free from environmental pollution, and cost is low, buys easily.
2, by changing dosage, can effectively control different material and handle the back the key technical indexes, technological parameter is reliable and stable.
3, the technical indicator of main several the spinnabilitys of rescutched tow after handling is near the cotton fiber technical indicator, and physical property is constant, keeps the original style of flax.
