Abstract
The invention provides a super bright polyester vortex spinning process and processing equipment thereof. The super bright polyester vortex spinning process comprises the following steps: stacking a super bright short fiber raw material for more than one week, increasing the vortex spinning air pressure by 10-25%, reducing the spindle spinning speed from 480 m/min to 380-400 m/min, and enabling the super bright short fiber raw material with electric charges to pass a magnetic field when in vortex spinning. Through adoption of the fiber cohesion increasing manners of increasing the vortex spinning air pressure, reducing the fabric speed and utilizing Lorenz force to control fiber flight, yarns with relatively high quality can be produced through bright yarn vortex spinning.
Description
Technical field
The present invention relates to spinning field, especially, be that a kind of weaving is with having greatly light terylene Technology of Air Vortex Spinning and process equipment thereof.
Background technology
Vortex spinning is that murata company of Japan improves on the basis of Air-Jet Spinning, the applicable spinning equipment (MVS) spinning cotton textiles of development.Air vortex spinning is to utilize fixed vortex spinning spool, replaces the rotor turned round at a high speed to carry out a kind of spinning method spinned.In a sense, air vortex spinning is only open-end spinning truly.Ribbon is fed by feed roll motor, becomes ultimate fibre through licker-in release, by means of the effect of air-flow, in cotton delivery pipe at a high speed feeding vortex tube.Vortex tube is made up of core pipe and outer tube two parts.Having three tangential air inlets on outer tube, lower end is connected with aerator, and blower fan constantly extracts air from pipe, and the air of outside enters in vortex tube along air inlet, produces gyrate air-flow.When rotating air-flow upwards and arriving core pipe, the fiber entered with cotton delivery pipe converges, and forms a cohesion fibrous ring along vortex tube inwall, and stably around vortex tube axis, revolution, twists resultant yarn by fiber at a high speed.Yarn is continuously drawn by extraction roller from guide eyelit and is wound into bobbin.The topmost feature of air vortex spinning is omitted the spinning parts of revolution at a high speed.The rotator inertia problem and bearing load problem (such as the cup of open-end spinning) that twisting parts cause at a high speed owing to using air-flow twisting to break away from, also has the air ring formed because of spinning to increase the problem (such as ring spinning) of spinning tension.Vortex spinning production efficiency is about 20 times of RING SPINNING, and yarn is bright and clean, and filoplume is few, and yarn interior does not exist moment of torsion, is efficient novel spinning mode.
Chemical fibre generally, has stronger gloss, but a lot of fabric is not required for having high light, so to carry out optical processing.Go in spinning liquid, just add appropriate matting agent (powder of high dispersion), destroy fiber surface, make fiber surface produce the irregular reflection to light to reach the purpose delustered.Conventional matting agent is titania powder, and general consumption is 0.5% 2%, adjusts its consumption and can get the fiber that gloss is different.In order to eliminate the gloss of fiber, using and add titanium dioxide (TiO 2) in the melt to cut down the gloss of fiber, if being not added with TiO 2 in the melt for bright yarn (or big bright yarn), adding 0.3% is semi-dull silk, is full-dull silk more than 0.3%.
Big bright yarn has the specific use of oneself, particularly preferably gloss to make it at many fashion series products in production and processing, has bigger purposes in dresses class product.But, having greatly light terylene short fiber to there are some problems in carrying out vortex spinning production process, topmost problem is because there is greatly light terylene short fiber owing to not using matting agent, fiber surface smoother, cause mutual frictional force between fiber on the weak side, cause yarn quality on the low side.Therefore, for having greatly the spinning of light terylene short fiber vortex spinning, need relevant processing method is adjusted, to obtaining high-quality yarn.
