Description
Technical field:
The present invention relates to the viscose filament yarn production field, particularly a kind of semi-continuous centrifugal spinning process that on an ingot position of semi-continuous centrifugal spinning machine, spins three rhizoids simultaneously.
Background technology:
Present as R535A, R535B semi-continuous centrifugal spinning machine, spin measuring pump of the former design and installation of face, a spinning head according to the every ingot of its standard instruction for mounting position, the utilization ratio of its equipment is low, the production cost height.When expanding the scale of production, can only solve by increasing the table of equipment number, investment is big, and floor space is big, and relevant auxiliary facility is many.
Chinese patent disclosed a kind of " many centrifugal cylinders of the every ingot of semi-continuous centrifugal spinning machine and control structure thereof " (patent No. is 00245222.7) and " the single channel multifibres is centrifugal to be spun and semi-continuous spinning machine and viscose spinning process thereof " (patent No. is CN00132054.8), it has provided the structure that the every ingot of a kind of semi-continuous centrifugal spinning machine position spins two rhizoids simultaneously in fact, this design philosophy is: on two electric ingot supports arranged side by side, every is equipped with six electric ingots and supporting centrifugal cylinder, causes corresponding a plurality of centrifugal cylinders in every ingot position and supporting electric ingot.
ZL200420061123.8 has proposed to be applicable to that viscose filament yarn one ingot position spins three semi-continuous centrifugal spinning machine simultaneously, but this spinning machine structure is people's silk product that can't obtain to satisfy client's quality requirement with the spinning technique of R535A, R535B spinning machine.After viscose glue will form three rhizoid bars, reaction, coiling on the ingot position, form three spinning cakes, the strand that solidifies in this process on roller and the acid removing roller becomes three by one or two, owing to solidify the variation of strand density on roller and the acid removing roller, will impact the physical property of strand coagulation reaction time, strand disacidify time, strand etc.If adopt three spinning heads, three cover funnel stands, centrifugal cylinder, electric ingot simply on the basis of an ingot monofilament and an ingot mariages, after each ingot position is increased to three rhizoid bars, if still adopt original technology and parameter thereof, in the whole process route, the adhering process of three rhizoid bars, acid bath index, solidify requirement or the like and all can't obtain up-to-standard strand.Scrape in addition that acid requires, the wire route also has problems, and will cause the strand doubling, strand can't meet the quality requirement, and the spinning operation difficulty is big, and it is also inhomogeneous to dye.These all are that semi-continuous centrifugal spinning machine existing structure designs indeterminable problem.
Therefore, present semi-continuous centrifugal spinning process can't directly spin three rhizoids under the condition that satisfy the spinning cake quality simultaneously on an ingot position, if will reach the purpose of three on an ingot, must do bigger improvement to technology.
Summary of the invention:
The purpose of this invention is to provide a kind of semi-continuous centrifugal spinning process that can really realize spinning simultaneously on the ingot position three rhizoid bars, adopt the present invention, can satisfy quality requirement and not increase under the situation of operating cost and floor space, realize that every ingot position spins the purpose of three rhizoids simultaneously.
Concrete technical scheme of the present invention is as follows:
A kind of novel semi-continuous centrifugal spinning process, an ingot position has the walking of three rhizoid bars simultaneously, its operation comprises the metering of glue, viscose glue, filters, spray silk, coagulating bath, scrape that acid, strand drawing-off, strand are solidified, strand disacidify, spinning cake coiling and molding, it is characterized in that:
In A, the glue operation, viscose ripening degree NH
4The Cl value is controlled at 8.8～13ml, and surface tension is 40～52dny, steam bubble number≤25/500ml, and viscose glue population after three roads filter (IIIF), candle shape filter is controlled at every milliliter of viscose glue≤100/below the 10 μ m;
In B, the coagulating bath operation, viscose glue is reacted with acid bath by the spinning head ejection and forms strand, 52～55 ℃ of its acid bath temperature, the sulfuric acid concentration of acid bath is (132-136) g/l, sodium sulfate concentration is (220～265) g/l, the acid bath surface tension is less than the viscose glue surface tension, acid bath proportion≤1.265g/ml;
In the described strand drafting process, adopt positive and negative drawing-off-2～25%;
In the described spinning cake coiling and molding operation, it is acid that spinning cake is, PH :≤4.
Described strand solidify in the operation on solidify roller length 230mm, down solidify roller length 280mm, it is several 27 ± 8 to solidify the roller wire ring, solidifies roller flight lead 5-10mm; Remove the last acid removing roller length 870mm in the strand acid operation, following acid removing roller length 890mm, acid removing roller wire ring number: interior 72 ± 5, in, outer 85 ± 8, acid removing roller flight lead 5-10mm.As solidifying roller, acid removing roller length variations, the wire ring number changes.
Beneficial effect of the present invention shows:
Novel semi-continuous centrifugal spinning process that the present invention is given and the novel spinning machine that is complementary have solved in the past unsolved concrete technical problem in three imaginations of an ingot.Adopt the present invention after each ingot position is increased to three rhizoid bars, this three rhizoids bar keeps relative position, not doubling, and the strand quality is good.And because the parameter of the parameter of viscose glue, acid bath, solidify roller wire ring number, solidify the roller flight lead, acid removing roller wire ring number, acid removing roller flight lead determine that make spinning more reliable, stable, operability is good, good, the follow-up Color of spinning cake quality is good.Adopt the present invention could really be implemented in the purpose that directly spins three rhizoids under the condition that satisfies the spinning cake quality on an ingot position simultaneously, comparing output with an ingot monofilament under the prerequisite of ensuring the quality of products increases by 200%, and comparing output with an ingot mariages increases by 50%.
