A method for preparing chitosan fiber tow-cut strips by using a stretch breaking machine comprises the following specific steps:
s1, preparation of chitosan fiber tow 8
The spinning method of chitosan fiber is a wet spinning method, firstly, dissolving chitosan in solvent (low-concentration acetic acid) to prepare spinning stock solution with a certain concentration, after filtering and defoaming, spraying the stock solution into a coagulating bath tank in a trickle shape from holes of a spinning nozzle by using pressure, coagulating into solid fiber in the coagulating bath tank, and then stretching, washing and drying to obtain chitosan fiber tows 8;
s2, preparation of chitosan fiber tow-cutting strips
The chitosan fiber tows 8 pass through between two guide rollers 101 of the filament spreading device 1, and then are flatly combed and spread by two filament spreading rollers 102; the unfolded chitosan fiber tows 8 enter two groups of delta-shaped stretch breaking parts, pass through the middles of the pre-stretch breaking leather roller 203 and the two pre-stretch breaking rollers 204 for pre-stretch breaking through pressurization, pass through the middles of the main stretch breaking leather roller 303 and the two main stretch breaking rollers 304 for main stretch breaking through pressurization, finally, the fiber strips after stretch breaking are bunched and condensed into strands through the horn-shaped bunching opening 402, and the strands are orderly wound on the winding barrels 404 for subsequent processing and use.
The principle of preparing the chitosan fiber tow-cut strip by the tow-cut method is as follows:
the drawing and cutting method, also called stretch breaking method, makes the chitosan fiber tow 8 pass through two or more pairs of rollers with increasing speed, makes the long tow be forced to stretch between the roller holding points to generate local breaking, the breaking part is the weakest point on the tow, but not at the same position on the tow; the broken fibers leave the holding point of the last pair of drawing rollers and move forwards, and are mutually crossed and gathered into a continuous strip, so that the macroscopic filament bundle shape is not interrupted. The length of the single fiber stretch-broken can be controlled by adjusting the gauge of the stretching roller and the number of stretching parts, and the length of the stretch-broken fiber is distributed in the short fiber bundle in unequal lengths.
The length of the fiber output main body of the main breaking device 3 is 38-40mm.
The pre-breaking pressurizing device 202 and the main breaking pressurizing device 302 adopt pneumatic pressurization, so that the pressurizing stability is enhanced, the pressure loss or the under-pressure phenomenon is prevented, and the power is 4.0Kw.
The speeds of the pre-breaking roller 204 and the main breaking roller 304 are sequentially and progressively increased, and in order to increase the strength and rigidity of the main closing part of the traction part, the gears of the pre-breaking roller 204 and the main breaking roller 304 are all made of high-strength and high-hardenability alloy steel; the pre-breaking leather roller 203 and the main breaking leather roller 303 are all high-gloss anti-pressure wear-resistant antistatic leather rollers.
The strand-discharging speed of the strand gathered and condensed into strands by the trumpet-shaped gathering port 402 is 25-50 m/min.
The industrial stretch-breaking method for chitosan tows disclosed by the invention bypasses the problem of net formation, and chitosan fiber stretch-breaking strips are directly formed, so that pure spinning is realized.
The invention fills the gap of the domestic chitosan stretch-breaking strip preparation process and production equipment. At present, no report related to the production of the chitosan drawn and cut strips exists at home and abroad. From our previous experimental studies, it is known that stretch breaking equipment is used for wool in a large number, but the equipment for stretch breaking the wool process is not suitable for chitosan fibers; further, since chitosan has a larger elongation than metal fibers, and cannot be used as a device for drawing and cutting metal wires, it is necessary to modify the chitosan fibers according to their properties.
The drawing and cutting strips can be directly subjected to pure spinning or blending in the drawing process, and the processes of cotton cleaning and cotton carding are bypassed, so that the problem that the chitosan fiber is difficult to form a net is solved; the raw material cost can be saved, and the production efficiency can be improved.
Broadens the product category of the chitosan fiber.
The invention has been described in connection with the accompanying drawings, it is to be understood that the invention is not limited to the specific embodiments disclosed, but is intended to cover various modifications, adaptations or uses of the invention, and all such modifications and variations are within the scope of the invention.

The spinning method of the chitosan fiber is a wet spinning method, firstly, the chitosan is dissolved in a solvent to prepare spinning stock solution with a certain concentration, after filtration and deaeration, the stock solution is sprayed into a coagulating bath tank in a trickle shape from holes of a spinning nozzle by pressure, and is coagulated into solid fiber in the coagulating bath tank, and then the solid fiber is stretched, washed and dried to obtain a chitosan fiber tow (8);
s2, preparing chitosan fiber drawing and cutting strips
The chitosan fiber tows (8) pass through the space between the two guide rollers (101) of the filament spreading device (1), and then are flattened and combed by the two filament spreading rollers (102); the stretched chitosan fiber tows (8) enter two groups of delta-shaped stretch-breaking parts, pass through the middles of a pre-stretch-breaking leather roller (203) and two pre-stretch-breaking rollers (204) for pre-stretch-breaking, pass through the middles of a main stretch-breaking leather roller (303) and two main stretch-breaking rollers (304) for main stretch-breaking, finally, the stretch-broken fiber strips are bunched and condensed into fiber strips through a trumpet-shaped bunching opening (402), and the fiber strips are orderly wound on a winding drum (404) to be convenient for subsequent processing and use.
7. The method for preparing the chitosan fiber tow strip by using the stretch-breaking machine as claimed in claim 6, wherein the length of the fiber output main body of the main stretch-breaking device (3) is 38-40mm.
8. The method for preparing the chitosan fiber tow-cut strip by using the stretch breaker as claimed in claim 7, wherein the pre-breaking pressurizing device (202) and the main stretch-breaking pressurizing device (302) adopt pneumatic pressurization with the power of 4.0Kw.
9. The method for preparing the chitosan fiber drawn and cut sliver by using the stretch breaker as claimed in claim 8, wherein the speeds of the pre-breaking roller (204) and the main breaking roller (304) are sequentially and incrementally set, and the gears of the pre-breaking roller (204) and the main breaking roller (304) are made of high-strength high-hardenability alloy steel; the pre-stretching breaking leather roller (203) and the main stretching breaking leather roller (303) are all highlight, pressure and wear resistant antistatic leather rollers.
10. The method for preparing the drawn and chopped chitosan fiber sliver by using the stretch breaking machine as claimed in claim 9, wherein the trumpet-shaped gathering mouth (402) gathers the sliver to form the sliver with the sliver discharging speed of 25-50 m/min.
