Abstract
A technology for spinning high-strength viscose filament includes conveying viscose, metering, filtering, spinning by spinneret, coagulating in bath, drafting, solidifying in the another bath, water washing, applying oil, baking and winding. Its apparatus is also disclosed.
Description
One, technical field: the present invention relates to field of textiles, specifically the present invention relates to high-strength viscose continuous yarn spinning technology and spinning machine.
Two, prior art: existing viscose filament yarn manufacturing technique has: centrifugally spin, semicontinuously three kinds of technologies such as spin and spin continuously.Centrifugal spin with semicontinuous spinning process in, viscose glue is expressed in the coagulating bath from shower nozzle and is shaped, the strand that solidifies by the bath face of drawing after after solidifying on the roller further regeneration, carry out wet concentration to the washing roller and handle, be shaped to spinning cake through tophan box; In continuous spinning process, viscose glue is shaped in the spinning glass tube through spinning head is extruded after, and the strand that solidifies wet concentration to the treatment tube is handled after coiling and molding is silk tin.The tradition viscose filament yarn is a kind of multifilament, and its filament number generally is not less than 2dtex, and Denier range is generally 44-666dtex; Because the fine content of first was all about 9% during the viscose glue of these three kinds of technologies was formed, all have only about 6% and contain alkali, it adopts single bath process to be shaped, zinc sulfate concentration is lower in the coagulating bath, because the characteristics of these spinning techniques and device layout, determine the fiber solidification forming too violent, caused the fibre section to form tangible zigzag skin-core structure; It is low to show as fibre strength, and fatigue performance is poor, is difficult to satisfy special requirement.
Three, Fa Ming purpose, in order to overcome the shortcoming of existing viscose filament yarn Processes and apparatus, the objective of the invention is to: a kind of new viscose rayon filament spinning skill is provided and implements the high-strength viscose continuous yarn spinning equipment of this method, to improve the quality of spinning, make the viscose filament yarn fiber have good intensity and fatigue performance, to satisfy special requirement.
Four, summary of the invention: the objective of the invention is to be implemented by following technical scheme: a kind of high-strength viscose long filament continuous spinning process and equipment, its spinning technique is realized by one roller multifibres continous mode viscose filament yarn spinning machine.Spinning machine partly is made up of viscose glue induction system, measuring pump, candle filter, spinning head, spin duct, spinning disc, washing roller, two baths, washing pipe, oil bath, drier roll and electric ingot system etc.
Viscose glue is by the viscose glue induction system, after the measuring pump metering, spin preceding filtration by candle filter, extrude by spinning head and to form the viscose glue thread, be configured as nascent strand with the coagulating bath effect in the level vial of viscose glue thread in immersing coagulating bath, nascent strand enters second coagulating bath and regenerates after carrying out first drawing-off between the spinning disc and second spinning disc, one or more strand through regeneration is washed processing to treatment tube after by the 3rd spinning disc drawing-off, after strand after washing is handled oils by oil bath, through drier roll oven dry back winding shaping.
Main technique feature of the present invention has been compared very big with traditional handicraft be high, its advantage is: (one), the process that adopts traditional viscose filament yarn to produce, in the viscose filament yarn production process, because fibre forming is too violent, causes the fibre section to be tangible zigzag skin-core structure (as shown in Figure 3); Viscose filament yarn of the present invention cross section is the full cortex construction (as shown in Figure 2) that is close to circle; (2), traditional viscose filament yarn is a kind of multifilament, its filament number generally is not less than 2dtex, its filament number of viscose filament yarn of the present invention can be low to moderate 0.8dtex; (3), traditional viscose filament yarn Denier range is generally 44-666dtex, viscose filament yarn Denier range of the present invention is 44-2200dtex; (4), traditional viscose filament yarn adopts single bath process to be shaped, the present invention adopts two-bath process to be shaped; (5), the present invention adopts a rhizoid bar or multi-filament bar to handle on a pair of washing roller; (6) one or more strand is dried on a pair of drier roll, and divides bull to reel.(7), the spinning glue that adopts of the present invention forms and is starkly lower than traditional viscose, the fine content of first is 5-7% in the viscose glue; (8), its sulfuric acid of coagulating bath, the sodium sulfate concentration of the present invention's employing are starkly lower than traditional viscose filament yarn coagulation bath composition, zinc sulfate concentration is apparently higher than traditional viscose filament yarn coagulation bath composition, and sulfuric acid concentration is that 60-80g/l, sodium sulfate concentration are that 150-180g/l, zinc sulfate concentration are 75-90g/l.
