Production process of novel high-performance bio-based textile material

Abstract

The invention relates to the field of bio-based material production, in particular to a production process of a high-performance bio-based textile new material, which comprises the following steps: introducing a sodium alginate solution into a spray head through pressurization, spraying the sodium alginate solution out of a spinneret orifice, arranging an air bag in contact with the pressurized sodium alginate solution in a wrapping manner in the spray head, one end, which is not wrapped, of the air bag is a free deformation end, a flow channel for discharging a calcium chloride solution is arranged in the spray head, the calcium chloride solution is guided into the flow channel in a pressurized manner and is sprayed out from the water spraying holes, and a check ring for controlling the size of an opening of the flow channel is arranged in the calcium chloride solution flow channel in a sliding manner. And the other end of the through groove is changed to different degrees under different pressures so as to change the adjustment of the blocking area of the through groove by the check ring, so that the discharge speed of the calcium chloride solution is synchronously increased or reduced along with the discharge speed of the sodium alginate solution, and the quality of the produced bio-based fiber is relatively uniform.

Description

technical field [0001] The invention relates to the field of production of bio-based materials, in particular to a production process of high-performance bio-based new textile materials. Background technique [0002] Bio-based materials are a kind of materials that are relatively "friendly" to the environment. Their degradable characteristics greatly reduce environmental pollution, and bio-based materials are made of crops, aquatic plants, and some animals as raw materials, and the raw materials are renewable. , greatly reducing the utilization of oil and meeting the requirements of environmental protection. [0003] The bio-based fiber material made of alginate purified from seaweed has the characteristics of green environmental protection, natural flame retardancy, and good biocompatibility. It can be used in medical and health materials, high-end health care clothing, home textiles and other fields. Has a better market environment. [0004] The use of alginate to prepar...

Problems solved by technology

[0005] The purpose of the present invention is to solve the following problems in the prior art: the preparation of fiber materials using alginate generally adopts wet spinning method, by applying alginate Fibrous filaments are sprayed into the coagulation solution to form fiber materials. The efficiency of the spinning and the speed of the coagulation solution must be strictly controlled during the production process. However, traditional production equipment uses separate control methods for the spinning and coagulation solution, which cannot be accurately controlled. Synchronized and coordinated control of both
