Abstract
The invention provides a production technology of tyre fabric for tyres. The production technology includes the operating steps of twisting, fabric weaving and rubber dipping. The tyre fabric is produced according to the parameters that a straight twisting machine, a warping machine and an air jet loom are adopted for production, the width of grey cloth is set between 155 cm and 160 cm, an arc-shaped spreading roller is changed into a three-finger full-range expander and a semi-range expander, the rubber dipping liquid is a Pexul system, the density of warps of reeds is reduced, the angle of a side warp tension drum is smaller by 1 degree to 5 degree than that of a middle tension drum, the replacing frequency of a rough-face shell wrapping the surface of a warp pacing roller is replaced once every 24 hours to 48 hours, and a roller on the rubber dipping machine is cleaned once every 48 hours to 72 hours. Due to the improvement in the production technology, the density of the warps of the tyre fabric tends to be consistent, not only are the texture and the structure guaranteed, but also the physical performance and the appearance quality of the tyre fabric are kept, rubber can permeate mutually easily in the calendaring process, the stress borne by a tyre can be consistent easily, side lines of the tyre are prevented from being exposed, and large potential safety hazards such as delaminating are avoided.
Description
Technical field
The present invention relates to a kind of textile production technique, particularly the production technology of cord fabric for a kind of tire.
Background technology
Cord fabric is to make warp with powerful strand, with in, ramuscule single thread makes latitude, knits the tire skeleton fabric of system.Weft yarn is fixing through line position, and warp claims again cord fabric thread, bears load.Cord fabric thread has cotton cord fabric thread, viscose cord fabric thread, polyamide fibre cord fabric thread, steel wire cord fabric thread, nylon curtain line, polypropylene fibre cord fabric thread, Armaid Cord Filament, carbon fiber cord fabric thread, PEN cord fabric thread etc.Due to the skeleton of cord fabric as the rubber such as tire, for being possessed, it bears immense pressure, the ability of impact load and sharp pounding, and require cord fabric thread to possess: 1. intensity and initial modulus are high; 2. heat-resisting; 3. endurance; 4. Stability Analysis of Structures; 5. can with the performances such as rubber adhesion.
But at present cord fabric is weaving, in immersing glue process, be subject to the impact of the many factors such as tension force, glue, temperature, cause limit portion to there are differences through line tension with middle, warp produces broadwise displacement, cause parallel to produce crooked, under identical broadwise projected length, curvature of parallel degree is higher, and warp density is larger; In addition cord both sides warp is one-sided stressed in broadwise, causes limit portion through close higher than centre.
Cord fabric be take individual layer use as main in tire, the institutional framework of cord fabric and warp density are had relatively high expectations, curtain is middle and limit portion is excessive through close difference, not only can affect curtain physical property and presentation quality, also can affect that glue in calender line interpenetrates and the uniformity of tire force, thereby cause tyre side naked wire, the larger potential safety hazard such as delamination.
Patent CN201320578861.9 discloses a kind of polyamide cord fabric, this cord fabric comprises crisscross warp and parallel, spacing between parallel is much larger than the spacing between warp, in each 20cm of both sides through distance between centers of tracks be greater than middle position through distance between centers of tracks, equidistantly arranging through distance between centers of tracks of middle position, within the scope of each 20cm of both sides through distance between centers of tracks distribution gradient, and within the scope of this, be positioned at outside through distance between centers of tracks be greater than be positioned at inner side through distance between centers of tracks.Although this patent by feed side portion through distance between centers of tracks overcome limit portion through close than the high problem causing in centre, but caused whole cord fabric warp density inconsistent, institutional framework defectiveness, also can affect that glue in calender line interpenetrates and the uniformity of tire force, produce tire safety problem.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides the production technology of cord fabric for a kind of tire, to solve in current cord fabric product limit portion through close higher than centre, cause cord fabric institutional framework defectiveness, discontinuity, cause tyre side naked wire, the problem of the larger potential safety hazard such as delamination.
The technical solution adopted in the present invention is: the production technology of cord fabric for a kind of tire, its operating procedure is followed successively by twisting, weaves cotton cloth, impregnation, adopt following parameter: (1) adopts electric ingot is the straight twister that the kind of drive, ingot tank are 230mm, it is 1600mm that employing comprises a plurality of disc overall diameters, interior diameter is 320mm, web distance is the warping machines of many warp beams of 2600mm, adopts the air-jet loom of electronic warp feeding, large capacity cloth rewinder to produce; (2) grey cloth width is set in to 155-160cm; (3) arc spreading roll is all made into three finger full width expanders and half range expander; (4) dipping solution is Pexul system; (5) adopt 14cm place, selvedge both sides progressively to reduce reed warp density; (6) limit portion through the angle of line tension cylinder than the little 1-5 ° of intermediate tension cylinder; (7) replacement frequency of the warp let-off roller surface of woven cloths machine parcel exasperate skin is 1 time/24-48h; (8) cleaning frequency of cement dipping machine upper roller is 1 time/48-72h.
As preferably, described step is set in 158cm by grey cloth width in (2).
As preferably, in described step (6), limit portion is less 3 ° than intermediate tension cylinder through the angle of line tension cylinder.
As preferably, in described step (7), the replacement frequency of the warp let-off roller surface of woven cloths machine parcel exasperate skin is 1 time/36h.
Compared with prior art, the invention has the beneficial effects as follows the improvement by production technology, the warp density integral body of cord fabric is reached unanimity, not only guaranteed institutional framework, curtain physical property and presentation quality have been kept, and be conducive to that glue in calender line interpenetrates and the uniformity of tire force, prevent tyre side naked wire, the larger potential safety hazard such as delamination.
