Abstract
The invented polytrimethylene terephthalate (PTT) second rove and double-rove feeding production process and product relates to the field of yam spinning technique of textile technology. Said invention utilizes the addition of process making first rove and double-rove be fed into spinning frame, and defines new blending ratio so as to overcome the defects of existent similar techniques. The product produced by adopting said invented new process is specially suitable for making high-grade knitted garment.
Description
Technical field:
The present invention relates to a kind of textile technology spinninging technical field.
Background technology:
Existing polytrimethylene terephthalate (PTT) fibrous fracture intensity is low, cohesive force is poor, adopt one rove, single rove feeding technology to spin, and exist the following technological deficiency: spinnability is poor; Bar evenness is poor; The single thread filoplume is many; Single end strength is low, is unfavorable for back-end production process.Need to improve the spinnability performance of polytrimethylene terephthalate (PTT) fiber product; Improve bar evenness; Improve the single thread fracture strength, reduce the single thread filoplume, be beneficial to later process production.
Summary of the invention:
The objective of the invention is to provide a kind of spinning property, raising bar evenness, raising single thread fracture strength index that can improve polytrimethylene terephthalate (PTT) fiber product, reduce the single thread filoplume, be beneficial to a kind of new process of later process production and products thereof.
The new technology of technical scheme of the present invention is by increase by one process of roving in traditional blending production technology; And, become single rove and be double roving feeding fine spining machine; Simultaneously, the new technology of technical scheme of the present invention determines that the blending ratio of polytrimethylene terephthalate (PTT) fiber and viscose is: polytrimethylene terephthalate (PTT) fiber: viscose=(20～80) %: (80～20) %; The number of the blended yarn of producing with this new technology, new blending ratio is 14tex～37tex (42
s～16
s).
The concrete technical characterictic of the technological process of production of the present invention is:
1. opening picking: will be to polytrimethylene terephthalate (PTT) fiber and viscose shredding, impurity elimination, mixed fully through the opening or cleaning cotton machine, make the mixed volume to the mixed fiber of polytrimethylene terephthalate (PTT) fiber and viscose of constant weight and length, for carding process is prepared.
Its important technological parameters: mixed volume weight: 12.5kg, quantitatively (g/m): 383, in addition, install antisticking device additional, increase pressure, and cotton layer is separated with the rove bar, prevent the sticking volume of cotton layer.
2. comb and parallel cotton fibers prior to spinning: the mixed fiber to polytrimethylene terephthalate (PTT) fiber and viscose carries out careful combing, removes impurity, fault, fully mixed back slivering.
Its important technological parameters: adopt light weight, quantitatively (g/5m): 18.0, cylinder speed (rpm): 329, licker-in cylinder speed ratio: 1.86: 1, the doff clothing model adopts 4535 * 2590, and cylinder～cover plate spaces (mm): 0.36,0.30,0.30,0.30,0.36.Its effect is: prevented the cylinder embossing, prevented to produce cotton knot, fiber is shifted smoothly.
3. two road draftings: improve the strip uniformity, make fiber fully mixed, improve the straightening of fibers depth of parallelism.
Its important technological parameters: adopt gently quantitatively, heavily pressurization, curve drawing suitably increases drafting force, and slubbing is more quantitative than two roads, drawing-off grasp bigger than normal.
| Operation | Quantitatively (g/5m) | ??E Always | ??E After | Roller gauge (mm) | Roller pressurization (kg) |
| In the lump | ??17.4 | ??8.4 | ??1.745 | ??11×18×15 | ??19×24×19 |
| Two also | ??17.0 | ??8.3 | ??1.375 | ??10.5×18×15 | ??19×24×19 |
4. two road rove: through drawing-off and twisting, further improve the separating degree of fiber, degree of stretching, and the uniformity.
Its important technological parameters: reasonable distribution drafting multiple, slubbing are than two road drawing-offs grasp bigger than normal, and the regular roving feeding slubbing adopts the amount of resetting, two roads adopt quantitatively light, heavily pressurization, and pressure increases by 10%, the proparea roller gauge increases 2mm, adopts delayed startup when driving to start, and makes the smooth drawing-off of fiber.
| Operation | Quantitatively (g/5m) | ?E Always | ?E After | Nylon block | The twist (twist with the fingers/10cm) | Roller gauge (mm) | Roller gauge (mm) |

| Two road rove | 2.0 | ?3.0 | ?1.32 | ??5.0 | ?5.77 | ?32×30 | ?28×14×14 |
5. spun yarn: through drawing-off, twisting back winding shaping.
Its important technological parameters: the parallel feeding of double roving, change the yarn winding-structure, the proparea roller gauge increases 3mm, and pressure increases by 10%.E
Always: 13～32, E
After: roller gauge (mm): 21 * 39, roller pressurization (kg): 17 * 10 * 10, twist factor (twist with the fingers/10cm): 335, nylon block: 3.0～5.0.
6. automatic winding: remove the fault in the yarn, impurity, and be wound into bobbin.
Its important technological parameters: N; 350; Short:140%D, 3mm; Long:40%D, 40mm; Thin:-30D, 40mm.
The specific embodiment:
When one process of roving of former use and single rove feeding fine spining machine were produced, the special property sent out yarn defect was many especially, and the rule bar is done many; Spinnability is poor, and broken end is many, and bar evenness is poor, and resultant yarn filoplume is many, and single thread force is low, produces instability, is unfavorable for the later process ordinary production.Through adopting production technology of the present invention, promptly adopt: two road process of roving and double roving feeding fine spining machine technology; Adopting blending ratio is that the number of yarn of the viscose fiber blending of polytrimethylene terephthalate (PTT) fiber of (20～80) % and (80～20) % is 14～37tex (42
s∽ 16
s) product, yarn quality is good, spinnability is strong, single thread force improves, filoplume reduces, bar is done evenly, its physical index reaches Q/WFBF 05-2004 standard, product belongs to Grade A to improve quality, and is 14～37tex (42 with the spun number of this technology
s∽ 16
s) knitted cloth that blended yarn is made into, cloth cover is bright and clean, even, good springiness, soft, dyeability under the normal temperature condition, just can dye fortunately, and lovely luster is particularly suitable for making high-grade knitted clothes.
