Problems solved by technology

[0005] The above-mentioned existing patents provide a solution for preparing biofibers with different sizes and mechanical properties. This technical solution is relatively complete, but in actual large-scale industrial production, biofibers can only reach the actual level after multiple times of water-bath drafting. Due to the calm water body in the existing production equipment for the drafting of biological fibers, the contact with the spun fibers is not sufficient, the degree of infiltration is limited, and the phenomenon of incomplete infiltration is prone to occur, resulting in uneven stretching and affecting the quality of the finished product

Embodiment 1

[0035] Such as Figure 1-6 As shown, a production equipment for bio-based fiber materials includes a support 1 and a main control box 2. The support 1 is equipped with a stock solution processing module, a silk forming module and a forming module that are sequentially matched, and the main control box 2 Cooperate with the stock solution processing module.

[0036] The raw liquid processing module includes a mixing tank 3, a conduit 4, a defoamer 5 and an output pipe 6. The support 1 is provided with a mixing tank 3 near the main control box 2. The mixing tank 3 is provided with a filter assembly that cooperates with the main control box 2. The outlet side of the mixing tank 3 communicates with the defoamer 5 through the conduit 4 , and an output pipe 6 is connected to the output end of the defoamer 5 .

[0037] The filament forming module includes a spinneret 7, a coagulation bath 8, a godet roller 9 and a filament forming roller group 10, a coagulation bath 8 is fixed on one...

Embodiment 2

[0043] The difference between this embodiment and Embodiment 1 is that when the spun fibers are drawn, the kinetic energy of blow drying is used to fluctuate the draft bath in the drawing bath 12, further increasing the degree of completeness of the spun fibers. degree.

[0044] Such as Figure 1-6 As shown, a production equipment for bio-based fiber materials includes a support 1 and a main control box 2. The support 1 is equipped with a stock solution processing module, a silk forming module and a forming module that are sequentially matched, and the main control box 2 Cooperate with the raw liquid processing module, the side of the bracket 1 is equipped with a drying mechanism 16 that matches with the forming module, and the forming module is provided with a wave mechanism 17 that cooperates with the drying mechanism 16 to operate synchronously.

[0045] The raw liquid processing module includes a mixing tank 3, a conduit 4, a defoamer 5 and an output pipe 6. The support 1...

Embodiment 3

[0054] Such as Figure 1-6 As shown, a drying method for production equipment of bio-based fiber materials, the specific steps are as follows:

[0055] 1) Pretreatment before spinning: After adding the high polymer production raw materials into the mixing tank 3, then adding an appropriate amount of solvent according to the ratio, mixing and dissolving to obtain the spinning stock solution, which is filtered and exported, and the spinning stock solution enters through the conduit 4 The defoamer 5 carries out the defoaming process, and is then exported to the next step through the output pipe 6;

[0056] 2) Wet spinning: add the coagulation liquid that has not passed the spinneret 7 to the coagulation bath 8 in advance, and the spinning stock solution is exported from the spinneret 7 after being processed, and the spinning is formed by the action of the coagulation liquid in the coagulation bath 8. The spinning filament bypasses the godet roller 9 and is drawn to the filament ...

Abstract

The invention provides production equipment and method for a bio-based fiber material, and relates to the technical field of fiber industrial production.The production equipment for the bio-based fiber material comprises a support and a main control box, and a stock solution treatment module, a filament forming module and a forming module which are matched in sequence are installed on the support; a drying mechanism matched with the forming module is loaded on one side of the support, a fluctuation mechanism matched with the drying mechanism to act synchronously is arranged in the forming module, and blowing drying is additionally arranged at the interval of two times of water bath infiltration, so that the stretching degree of spinning fibers before the spinning fibers enter the next time of drafting water bath is increased. In this way, water bath is conducted again, the complete degree of spinning fiber infiltration can be remarkably increased, the fluctuation mechanism synchronously acts by using a motor to drive a rotating shaft in the drying mechanism to rotate, a turning plate is made to turn over back and forth relative to a base, drafting bath liquid fluctuates in a drafting bath tank, and the complete degree of spinning fiber infiltration is increased.

Description

technical field [0001] The invention relates to the technical field of fiber industrial production, in particular to a production equipment and method of bio-based fiber materials. Background technique [0002] Bio-based fibers refer to fibers made from organisms themselves or their extracts, such as polylactic acid fibers made from starchy agricultural products such as corn, wheat, and sugar beets, and alginate fibers made from brown algae plants. [0003] Synthetic fibers in traditional textiles are generally made of petrochemical raw materials. Most of the discarded old clothes are disposed of by landfill and incineration, causing serious environmental pollution. With the increasing scarcity of petroleum resources and the awakening of people's awareness of environmental protection, Governments of various countries have taken various measures to reduce the use of petroleum resources and look for more environmentally friendly renewable resources to replace them. [0004] T...
