Problems solved by technology

[0002] Flax fiber is one of the high-quality textile raw materials, which has the advantages of coolness, breathability, antibacterial, etc., but at the same time has the disadvantages of poor dyeability, manifested in: low dyeing rate, low color fixing rate and poor color fastness, etc.
At present, this shortcoming has not been solved well. The traditional treatment process has a long existence time, high energy consumption, poor fiber quality and spinnability, and has certain pollution to the natural environment.

Abstract

The invention relates to a modification method of linen fiber. The modification method comprises following steps: (1) linen fiber is subjected to opening, and impurities are removed; (2) linen fiber is immersed in a urea solution for 30 to 50min; (3) after immersion, linen fiber is delivered into a microwave oven for 3 to 5min of heating so as to remove alkali solutions; (6) linen fiber obtained via step (5) is immersed in a mixed solution of sulfuric acid, sodium sulfate, and zinc sulfate for acid bath; (7) linen fiber is washed with clear water until pH value of the obtained linen fiber is adjusted to be 7; (8) the linen fiber is delivered into a centrifugal dehydrator for 3 to 5min of dehydration; and (9) the obtained linen yarn is dried for 60 to 90min. Dyeing of the treated linen fiber is convenient to realize.

Description

technical field [0001] The invention relates to a modification method of flax fiber. Background technique [0002] Flax fiber is one of the high-quality textile raw materials. It has the advantages of being cool, breathable, and antibacterial, but it also has the disadvantages of poor dyeability, which are manifested in low dye uptake, low color fixation, and poor color fastness. At present, this shortcoming has not been well solved. The traditional treatment process has a long existence time, high energy consumption, poor fiber quality and spinnability, and has certain pollution to the natural environment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a treatment method which is efficient, environment-friendly and capable of improving the dyeing rate and color fixation rate of flax fibers. [0004] In order to solve the above problems, the technical solution adopted by the present invention is: it is realized...
