Abstract
The invention discloses a spinning method for polyester cationic composite yarns, which comprises the following steps: respectively allowing PET (Polyethylene Terephthalate) slices and cationic slices to be subjected to storage bin processing, pre-crystallization, drying, extrusion melting and filtering so as to obtain respective melts; placing the two melts into the same spinning manifold, wherein one melt is subjected to metering pump processing, yarn jetting, lateral blowing, bundling, oiling and yarn guiding plate processing so as to obtain polyester filaments and the other melt is subjected to metering pump processing, yarn jetting, lateral blowing, bundling, oiling and hot roller processing, so as to obtain cationic filaments; allowing the two filaments to directly pass through a common wire stitching machine for mixing, drawing and twisting, and finally obtaining the polyester cationic composite yarns through reeling. The method has the advantages that spinning procedures for the polyester cationic composite yarns are intensively controlled; the composite yarn product can be produced by one set of equipment, so that the speed is greatly improved, so is the efficiency; the quality is stable, the weight and the length are both set; and the weaving efficiency of downstream enterprises is also greatly improved.
Description
Technical field
The present invention relates to a kind of spinning process of textiles, particularly a kind of terylene CATION compound silk spinning process.
Background technology
Terylene CATION compound silk is with PET, CATION section fusion, passes through melt pipeline separately respectively, by different spinnerets extrusion moldings, mixes fibre through Network device then and is combined into terylene CATION compound silk.Terylene and CATION composite spinning be with multiple fiber interweaving, can obtain an effect of bathing double-colored or polychrome after dyeing and finishing, can make pattern flower type that third dimension is arranged, and simplified dyeing and printing process, saved the dye well energy resource consumption.
The traditional mode of production of terylene CATION compound silk is to adopt independently spinning equipment to produce polyester filament and CATION long filament respectively, and then that these two kinds of silks are compound on equipment complex, compound speed has only hundreds of rice per minute.There are practical problems such as equipment investment is big, recruitment is many, land seizure is many, energy resource consumption is high, production efficiency is low, complex procedures, control difficulty, finally influence quality, cost and the selling price of product, the decline of the power that directly constitutes competition.
Summary of the invention
Goal of the invention: at the problems referred to above, the purpose of this invention is to provide that a kind of operation is simply concentrated, equipment concentrate be convenient to manage, terylene CATION compound silk spinning process that productive rate improves.
Technical scheme: a kind of terylene CATION compound silk spinning process, PET is cut into slices, the CATION section is respectively through feed bin, pre-crystallization, dry, extrusion molten, filtration obtains melt separately, after two kinds of melts enter same spinning manifold, one the tunnel through measuring pump, the spray silk, lateral blowing, boundling oils, draw-off godet makes polyester filament, another road is through measuring pump, the spray silk, lateral blowing, boundling oils, hot-rolling makes the CATION long filament, the described polyester filament and the described CATION long filament that make directly are incorporated into the power networks through common Network device blend drafting, make described terylene CATION compound silk behind the coiling.
Described CATION section is CDP section or ECDP section or NECDP section.
Described spinning manifold is with casing dual circuit or two casing dual circuit.If making the raw material section of polyester filament and CATION long filament is two kinds of kinds, and the melt temperature of two kinds of sections differs in 5 ℃, can adopt the way of dividing pipeline with casing, only need in the spinning manifold pipeline separately.If making the raw material section of polyester filament and CATION long filament is two kinds of kinds, and the melt temperature of two kinds of sections differs more than 5 ℃, just needs to adopt the way of two casing dual circuits.
Described Network device is the AWA Network device.
Beneficial effect: compared with prior art, advantage of the present invention is the spinning process centralized Control with terylene CATION compound silk, on a set of equipment, just can directly produce the compound silk product, speed significantly improves, efficient improves greatly, and stay in grade, reset length surely, also improved the weaving efficiency of down-stream enterprise greatly.
Description of drawings
Accompanying drawing is a process chart of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment only is used to the present invention is described and is not used in and limit the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
As shown in drawings, a kind of terylene CATION compound silk spinning process, PET is cut into slices, the CATION section is respectively through feed bin, pre-crystallization, the equipment drying, the screw extruder extrusion molten, filtration obtains melt separately, after two kinds of melts enter same spinning manifold, one the tunnel through measuring pump, the spray silk, lateral blowing, boundling oils, draw-off godet A, draw-off godet B makes polyester filament, another road is through measuring pump, the spray silk, lateral blowing, boundling oils, hot-rolling A, hot-rolling B makes the CATION long filament, the polyester filament and the CATION long filament that make directly are incorporated into the power networks through common Network device blend drafting, make terylene CATION compound silk behind the coiling.
Because the structure of spinning manifold is by the raw material section decision that makes polyester filament and CATION long filament among the present invention.If making the raw material section of polyester filament and CATION long filament is two kinds of kinds, and the melt temperature of two kinds of sections differs in 5 ℃, can adopt the way of dividing pipeline with casing, only need in the spinning manifold pipeline separately.If making the raw material section of polyester filament and CATION long filament is two kinds of kinds, and the melt temperature of two kinds of sections differs more than 5 ℃, just needs to adopt the way of two casing dual circuits.
The terylene CATION compound silk properties of product that the present invention makes are as follows after tested:
| Project | Standard | Actual measurement |
| Line density (dtex) | 55 | 55.2 |
| Line density deviation (%) | ±2 | 0.3 |
| Line density CV(%) | ≤1.7 | 0.9 |
| Fracture strength (cN/dtex) | ≥3.0 | 3.6 |
| Fracture strength CV value (%) | ≤9.0 | 5.8 |
| Elongation at break (%) | 28±6.0 | 31.5 |
| Extension at break CV value (%) | ≤19 | 11.7 |
| Boiling water shrinkage (%) | 13±1.2 | 13.3 |
| Dyeing uniformity (ash card) level | ≥4.0 | 4.0 |
| Oil content (%) | 0.7±0.35 | 0.75 |
