Embodiment 1

[0018] A preparation method of high elasticity chitosan underwear fabric, is characterized in that, comprises the following steps:

[0019] (1) Dissolve chitosan in 1% (v / v) acetic acid, stir until completely dissolved to obtain a 0.15g / mL chitosan solution, add dodecanal to the solution, stir for 2 hours, and then After adding 10% NaOH solution to adjust the pH of the system to 4-5, the NaBH 4 Slowly add it to the solution with dodecanal in a molar ratio of 3:1 within 1 hour. After reacting for 1 hour, after the pH of the reaction system rises to 5-6, adjust the pH of the system to 9 with 10% NaOH solution. -10, until the precipitate is separated, filter, wash the precipitate with water to neutrality, then extract with ethanol in a Soxhlet extractor for more than 12 hours, remove the remaining dodecanal and inorganic substances, and dry to obtain a hydrophobic modified shell glycans;

[0020] (2) Mix 28 parts of hydrophobic chitosan, 63 parts of tetrahydrofuran, 0.5 part of...

Embodiment 2

[0023] A preparation method of high elasticity chitosan underwear fabric, is characterized in that, comprises the following steps:

[0024] (1) Dissolve chitosan in 1.5% (v / v) acetic acid, stir until completely dissolved to obtain a 0.12g / mL chitosan solution, add dodecanal to the solution, stir for 2 hours, and then After adding 9% NaOH solution to adjust the pH of the system to 4-5, the NaBH 4 Add dodecanal to the solution slowly within 1 hour at a molar ratio of 3:1. After reacting for 1 hour, after the pH of the reaction system rises to 5-6, use 9% NaOH solution to adjust the pH of the system to 9. -10, until the precipitate is separated, filter, wash the precipitate with water to neutrality, then extract with ethanol in a Soxhlet extractor for more than 12 hours, remove the remaining dodecanal and inorganic substances, and dry to obtain a hydrophobic modified shell glycans;

Abstract

The invention belongs to a novel fiber and composite material preparation technology of a polymer material in a novel material, and relates to the field of fiber fabric production, in particular to apreparation method of a high elasticity chitosan underwear fabric. The method firstly prepares hydrophobic chitosan by hydrophobic modification on chitosan using dodecyl aldehyde; the hydrophobic chitosan, tetrahydrofuran, a natural antibacterial agent, a natural antioxidant and a spinning aid are uniformly mixed, and after the electrospinning treatment, an antibacterial chitosan fiber of the traditional Chinese medicine is obtained through drying; finally, the antibacterial chitosan fiber of the traditional Chinese medicine, the spandex, a pearl viscose fiber, a modal fiber and a cotton fiberare blended to obtain the high elastic chitosan underwear fabric. The chitosan underwear fabric not only has good elasticity, good skin-friendly property and strong moisture absorption and permeability, but also has antibacterial health care effect.

Description

technical field [0001] The invention belongs to the preparation technology of novel fibers and composite materials of polymer materials in new materials, and relates to the field of fiber fabric production, in particular to a highly elastic chitosan underwear fabric and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, people's awareness of health and health care is getting stronger and stronger, and the requirements for fabrics for clothing are also constantly improving. Nowadays, multi-functional fabrics are more and more favored by consumers. It is people's inner calling to wear healthy and beautiful clothes and enjoy the new life brought by new materials. [0003] Chitosan fiber is a kind of positively charged animal fiber in nature. It has unsaturated cationic groups in its molecules, so it has a strong adsorption effect on various harmful substances and harmful bacteria with negative charges, so th...
