Embodiment 1

[0018] A treatment method for improving the mechanical properties of flax yarn, comprising the following steps:

[0019] (1) Cellulase treatment: Treat the linen yarn with cellulase solution for 12 minutes, then take out the linen yarn, soak the linen yarn in absolute ethanol for 40 seconds, then take it out, and let it dry naturally to constant weight;

[0020] (2) Modification treatment: Add the above treated flax yarn to deionized water in a mass ratio of 1:10, and then keep it in a water bath at 40°C for 30 minutes to obtain a flax yarn dispersion, and add the initiator to deionized water , to prepare an initiator solution with a mass fraction of 2.1%, add an initiator solution with a quality of 10% of the flax yarn dispersion, stir evenly, and then dropwise add 10% of the flax yarn dispersion to the flax dispersion. Ethylacrylamide solution was evenly added dropwise in a water bath at 75°C for 1.5 hours, and then kept for 1 hour to obtain a mixed dispersion. Adjust the pH...

Embodiment 2

[0030] A treatment method for improving the mechanical properties of flax yarn, comprising the following steps:

[0031] (1) Cellulase treatment: Treat the linen yarn with cellulase solution for 15 minutes, then take out the linen yarn, soak the linen yarn in absolute ethanol for 50 seconds, then take it out, and let it dry naturally to constant weight;

[0032] (2) Modification treatment: add the above treated flax yarn to deionized water at a mass ratio of 1:12, and then keep it in a water bath at 40°C for 30 minutes to obtain a flax yarn dispersion, and add the initiator to deionized water , to prepare an initiator solution with a mass fraction of 2.1%, add an initiator solution with a quality of 10% of the flax yarn dispersion, stir evenly, and then dropwise add 10% of the flax yarn dispersion to the flax dispersion.

The tensile property of the flax yarns treated by using the method disclosed by the invention isgreatly improved.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a treatment method for improving the mechanical properties of flax yarn. Background technique [0002] Linen fabric has unique styles such as good hygienic performance, moisture absorption, fast moisture dissipation, breathability and smoothness, natural texture, soft tone, crisp and generous, and has been welcomed by consumers at home and abroad in recent years. However, due to the high degree of crystallinity and orientation of flax fiber, the elongation at break is small, and the fabric is easy to wrinkle. Contents of the invention [0003] The purpose of the present invention is to provide a treatment method for improving the mechanical properties of flax yarn aiming at the existing problems. [0004] The present invention is achieved through the following technical solutions: [0005] A treatment method for improving the mechanical properties of fla...
