Problems solved by technology

The horn melon fiber is a natural plant fiber grown from the horn melon seeds. Its basic component is composed of cellulose. The longitudinal surface of the fiber is smooth without distortion, and the hollowness of the cross section is as high as 80%-90%. It is an urgent development and The natural fiber is used, but the croissant melon fiber has high rigidity and no natural curl, which is unfavorable to the spinning of the fiber

Embodiment 1

[0023] The croissant melon fiber is pre-washed with anionic and nonionic surfactants at a temperature of 90°C for 60 minutes and a pH value of 9-10, then washed with water and dried. Immerse the pretreated croissant melon fiber in a polyurethane solution with a concentration of 10%, immerse it at room temperature for 5 minutes, and the bath ratio is 1:40, and finally use a centrifuge to remove excess treatment solution, and dry it in an oven at 70°C Dry. The processed croissant melon fiber increases in weight by 8.5%, the elongation at break increases by 3%, and the modulus of elasticity increases by 4%.

Embodiment 2

[0025] The croissant melon fiber is pre-washed with anionic and nonionic surfactants at a temperature of 90°C for 60 minutes and a pH value of 9-10, then washed with water and dried. Immerse the pretreated croissant melon fibers in a 3% polyvinyl alcohol solution for 5 minutes at room temperature with a bath ratio of 1:50. Finally, use a centrifuge to remove excess treatment solution and dry it. The processed croissant melon fiber increases in weight by 3.5%, the elongation at break increases by 2.5%, and the modulus of elasticity increases by 3%.

Abstract

A related method for improving calotropis gigantea fiber elastic modulus comprises performing washing pretreatment on calotropis gigantea fiber; dipping the pretreated calotropis gigantea fiber into a processing agent solution; and taking out calotropis gigantea fiber dipped in the processing agent solution, centrifuging and drying. The method is simple to operate, the processed calotropis gigantea fiber is increased in both breaking elongation and elastic modulus, and the method possesses certain meaning for alleviating the situation that cotton and other natural fiber resource is limited and exploiting a new ecological environment-friendly fiber material.

Description

technical field [0001] The invention belongs to the field of finishing fiber of horned melon, and in particular relates to a method for improving the elastic modulus of the fiber of horned melon. Background technique [0002] Croissant melon is one of the plants with potential utilization discovered in recent years. It is distributed in tropical and subtropical regions of Asia and Africa. It will become another new green natural plant fiber with extensive planting and application significance after cotton fiber. , The resulting industry has broad development potential and space. The horn melon fiber is a natural plant fiber grown from the horn melon seeds. Its basic component is composed of cellulose. The longitudinal surface of the fiber is smooth without distortion, and the hollowness of the cross section is as high as 80%-90%. It is an urgent development and The natural fiber is used, but the croissant melon fiber has high rigidity and no natural curl, which is unfavorab...
