The specific embodiment
This tight type spinning is woven into tubulose with latticed suction and collection circle 4 by warp 7 and parallel 8, the cell size of fabric is greater than 3000/square centimeter, warp 7 is approximately 90 ± 0.03 degree with the angle of cut of parallel 8, and, the place, intertwined point of warp 7 and parallel 8 after HEAT SETTING mutually enantiotropy locate.Suction and collection circle 4 is driven by traction wheel 5, the drive area 10 of gearing has been set at the both ends of tubulose suction and collection circle 4, the performance characteristic of this drive area 10 is: its hardness can be greater than the poly-district 11 of the suction that is positioned at the middle part, also may be that its thickness can be greater than the poly-district 11 of the suction that is positioned at the middle part, like this, when traction wheel 5 drives suction and collection circle 4 rotations, just have good net synchronization capability.The poly-district 11 of the suction of inhaling poly-effect has been set at the middle part of suction and collection circle 4, inhaling the hole of gathering and be woven into by graticule in poly-district 11, the effect of inhaling poly-district 11 is to inhale and gathers and the poly-fiber slivering of volume, requirement has an amount of ventilative and concave deformation ability, and the weaving process of inhaling poly-district is: 1, reduce this regional longitude and latitude intertwined point during tatting; Or 2, reduce the filling density in this district during tatting; Or 3, select a thinner yarn during tatting for use; Or 4, when HEAT SETTING, reduce to inhale the setting temperature in poly-district, reduce its amount of contraction.
Drive area 10 can be directly be interwoven by the graticule same with inhaling poly-district 11, but the graticule density that is positioned at drive area 10 makes the fabric of drive area 10 more abundant greater than the graticule density of inhaling poly-district 11, has good ABRASION RESISTANCE and friction resistant performance.Braiding can be adopted following method during drive area 10: the longitude and latitude intertwined point 13 that 1, increases drive area during tatting; Or 2, increase the filling density of drive area during tatting; Or 3, change the weft yarn number in this district during tatting, select low count yarn for use; Or 4, when HEAT SETTING, improve the heat setting temperature of drive area, to increase its amount of contraction.
As another kind of form, also can engage to have at drive area 10 increases frictional force and the knitting layer that improves anti-wear performance, and this knitting layer can be a braided fabric, utilizes adhesive to be bonded in the both ends of suction and collection circle again; Also can whole grid ring adopt same thread count.
This tight type spinning is as follows with the manufacture method of latticed suction and collection circle:
A, material choice: select diameter less than 0.1 millimeter filament chemical-fibres filaments as warp and parallel, the diameter of graticule can be the same, also can be different, but must guarantee that fabric blank has 2500/square centimeter cell size, putting before this, select thicker chemical-fibres filaments as far as possible, to improve its anti-wear performance; Selected chemical-fibres filaments should have higher crocking resistance, the heat endurance of appropriateness, and after guaranteeing continuously long-time running, the mesh of suction and collection circle is indeformable.
B, warping: the requirement by the diameter and the warp count of suction and collection circle is organized into accordingly through axle.
C, weave: the suction and collection circle blank of on inkle loom, weaving out band shape tubulose, the cell size of blank requires to be not less than 2800/square centimeter, the angle of cut of warp and parallel is approximately 90 ± 0.03 degree, can plain weave when weaving or the complex form braiding of twill or satin weave or plain weave and twill and satin weave, under special circumstances, do not decoherence, can lace stitch be set at interval by Len req for guaranteeing the suction and collection circle blank section parallel after the cutting, by interweaving between the graticule fastening parallel, it is not decoherenced.When braiding, the graticule that is positioned at the suction and collection circle two ends can be provided with closeer, so that formed the drive area 10 of gearing at the both ends of tubulose suction and collection circle 4, then form the poly-district 11 of the suction of dredging at the middle part.
Woven requirement has two, and one is different with general fabric requirement, and it is not the surface that forms fabric through weft yarn that the tissue of suction and collection circle blank requires, but the mesh that forms between the fabric graticule requires four jiaos of mesh clear, and the edge is vertical mutually; Its two, what determine graticule density is not fabric thickness, but what (being cell size) of the mesh that forms between the graticule in the unit are require greater than 2500/square centimeter.
D, cutting: utilize the high-temperature machining cutter will descend the blank behind the machine to be cut into the individual tubes material, its cutting temperature is higher than the fusion point of the chemical fibre mono filament that cuts, the purpose of thermal cutting is merging mutually through weft yarn on the single suction and collection circle pipe material section that makes after the cut-out, in order to avoid decoherence, its main points are that the cutter temperature should be greater than the fusing point of this chemical-fibres filaments, and used thermal source can be resistance wire or height, medium frequency induction power supply or other thermal source (as laser beam etc.).To the woven grid ring of polyamide fibre 66 long filaments, the cutter temperature should be controlled between 245 ℃～265 ℃; Temperature to the woven grid ring cutter of polyester filament should be controlled between 250 ℃～265 ℃.Said temperature control principle should be according to all multifactor selection of material purity, working environment when practical operation.
E, HEAT SETTING: the pipe material after will cutting is placed on the heatable plug of flexible support, but put into the heating muff of radial contraction, radially pressurize to sleeve pipe again, heat to plug simultaneously, make pipe material radially with axial shrinkage, the cell size in the unit are is increased.After HEAT SETTING, the cell size of pipe material requires to be not less than 3000/square centimeter, and general, its heating-up temperature should be higher than the softening point temperature of this fiber, is lower than the fusion point temperature of this fiber.
HEAT SETTING is one of core process of the present invention, and its effect mainly contains four, 1, eliminate stress, through HEAT SETTING, except eliminating the original stretching that general chemical ﹠ blended fabric all has,, has important effect for eliminate the powerful drafting stress that this product produces in weaving process.In the present invention, be to guarantee the vertical relation between the fabric graticule, strengthened drafting tension and throwed a spear power that this makes that stress ratio is bigger in the fabric, therefore must be eliminated.2, improve the cell size of fabric, in order to improve the anti-wear performance of suction and collection circle, often adopt thicker graticule when selecting material as far as possible, therefore, be difficult to directly obtain 3000/square centimeter cell size by weaving, by after this operation, the thermal contraction of graticule is when eliminating stress, increase the cell size of fabric in the unit are again, can obtain 3000/square centimeter cell size easily.3, prolong the service life of suction and collection circle, because suction and collection circle in actual use, be in for a long time under the Frotteurism with yarn, fricative heat accumulation, to cause the thermal deformation of chemical-fibres filaments, thus reduction of service life, after the elevated temperature heat typing, suction and collection circle has the predeformation of opposing thermal deformation, thereby has prolonged service life.4, locate through elevated temperature heat typing back phase enantiotropy between the graticule, because grid ring in use, rightabout frictional force is born on the Internal and external cycle surface, add that the frictional force of filament own is very little again, so, cause graticule to produce displacement in the use easily and cause the mesh distortion, poly-effect is inhaled in influence, therefore, be provided with higher setting temperature and typing pressure especially, make through the location that is meshing with each other between the grid ring graticule of high-temperature shaping, its intuitively image be: after the grid ring under the common setting temperature was disassembled, its graticule was straight single line, and after the grid ring under the high-temperature shaping of the present invention disassembles, its graticule has tangible complications, and its tortuous rule equals the rule that interweaves of grid ring fabric tissue.
The setting temperature of elevated temperature heat typing is much higher than chemical fibre heat setting temperature commonly used, and traditional heat setting temperature is approximately the vitrification point of this chemical fibre.In the present invention, then should be near the softening point temperature of this chemical fibre.To the woven grid ring of polyamide fibre 66 long filaments, the used temperature of finalizing the design is controlled between 170 ℃～230 ℃, to the woven grid ring of terylene, setting temperature is controlled between 180 ℃～240 ℃, should select according to factors such as the purity of material, working environments during practical operation.Shaping time should adapt with setting temperature, and when setting temperature was higher, the time can suitably lack, otherwise, then should grow, even to guarantee thermal diffusion.The wettability of considering higher setting temperature and suitable chemical fibre filament long filament is relatively poor, and used thermal source is with heated dry air or directly adopt electric hot plate for well, and saturated vapor or boiling water are difficult to reach the contractive effect of expection.In when cooling, the suction and collection circle pipe material behind high-temperature shaping directly drops in the water below 10 ℃, and it is cooled off rapidly, and effect is to make between the fibrous inside molecule mutual alignment freeze very soon and be fixed up.Typing pressure is 0.1～1 kg/cm (generally should be higher by 5～30% than common typing pressure), and pressure too conference causes the graticule gross distortion, has influence on the shape in hole, thereby has influence on the air permeable effect of suction and collection circle; Pressure is too little, does not just reach the typing effect of requirement, and is generally speaking, relevant with the fibrous material that is adopted.
