In the HEAT SETTING treatment process parameter for the papermaking forming web, maximum temperature is a key parameter.Maximum temperature is less than the softening point of monofilament in theory, but under a suitable maximum temperature, temperature is high more, and the time of HEAT SETTING is short more, better effects if.For monofilament polyester and the woven papermaking wire-cloth of nylon monofilament, present HEAT SETTING maximum temperature generally is no more than 180 ℃, and its heating method has nothing in common with each other and relative complex.
[summary of the invention]
The technical problem to be solved in the present invention provides a kind of simple and easy to do papermaking wire-cloth HEAT SETTING post-processing approach.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is, a kind of HEAT SETTING post-processing approach of papermaking wire-cloth, described papermaking wire-cloth be bottom by monofilament polyester and the woven three-layer paper making forming web of nylon monofilament, may further comprise the steps:
1) papermaking wire-cloth to be shaped being stitched into annular casing along two of warp direction at the uniform velocity turns round with cylinder on two of setting machine parallel cylinders, make the papermaking wire-cloth hot blast thermal treatment zone by setting machine continuously, purpose be guarantee papermaking wire-cloth can be in the thermal treatment zone full and uniform being heated;
2) initial temperature of the thermal treatment zone is 80 ℃, and heating-up temperature progressively increases along with the revolution of papermaking wire-cloth, reaches 195 ℃ maximum temperature until temperature;
3) in the papermaking wire-cloth heating, papermaking wire-cloth is vertically applied tensile stress, when initial temperature was 80 ℃, the initial tension force between two parallel cylinders was 2.5kg/cm; Along with the increase of temperature, the also corresponding thereupon increase of the tension force between two parallel cylinders, tension force reaches maximum when reaching maximum temperature;
4) papermaking wire-cloth continues revolution 2～3 circles when maximum temperature, and it is constant to keep maximum tension simultaneously under the maximum temperature condition;
5) descend by turning around for every time then 60 ℃ thermograde drop to about 60 ℃ up to temperature, and tension force also progressively drops in 60～80% scopes of maximum tension, promptly finishes once to add the HEAT SETTING processing procedure.
As preferably, step 2) the leading portion amplification of described heating-up temperature is 20 ℃.
As preferably, step 2) the stage casing amplification of described heating-up temperature is 15 ℃.
As preferably, step 2) the back segment amplification of described heating-up temperature is 10 ℃.
As preferably, the described maximum tension of step 3) is 20～25kg/cm.
As preferably, in the HEAT SETTING process with the control parameter of extensibility as warp direction stretching, described extensibility=(finishing length-initial length)/initial length, described initial length be under the initial tension force papermaking wire-cloth along warp-wise length, described end length is the warp-wise length of papermaking wire-cloth when last lap finishes under the maximum temperature condition; The control range of described extensibility is 10%～20%.
As preferably, in the HEAT SETTING process with the control parameter of relaxation shrinkage as the papermaking wire-cloth width, described relaxation shrinkage=(initial width-end width)/initial width, described initial width be under the initial tension force papermaking wire-cloth along the width of broadwise, described end width be when last lap finishes under the maximum temperature condition papermaking wire-cloth along the width of broadwise; Described relaxation shrinkage is controlled in 9%～15% the scope.
The essence of HEAT SETTING is to eliminate the stress and the high elastic deformation of fibrous inside under the higher temperature rapidly, makes high elastic deformation be converted into plastic deformation, and settles out under new state.
The raw material of current papermaking wire-cloth is the thermoplastic synthetic fiber, and its HEAT SETTING process is that macromolecular chain thaws, and spreads and readjusts, and sets up the process of new more fine and close and rock-steady structure.
In view of the foregoing, following factor has material impact to the HEAT SETTING effect:
(1) temperature: heat setting temperature must be selected to be higher than the high polymer vitrification point and be lower than in the scope of softening point temperature.The temperature height, required shaping time is short, but temperature is too high, will cause that fiber strength seriously descends.Also must keep the continual and steady of temperature in the HEAT SETTING process, bigger fluctuation can not occur, otherwise can cause the difference on the finished product typing effect.
(2) time: under the uniform temperature, for the relaxation that makes crystallization again carry out complete fully, just must guarantee certain shaping time.Shaping time on heat setting machine is embodied in the speed of the logical superheated header of papermaking wire-cloth.
(3) extensibility: when HEAT SETTING, papermaking wire-cloth is carried out certain stretching, help eliminating papermaking wire-cloth weaving process produce irregular through line tension, and can improve the distributed architecture of papermaking wire-cloth, very favourable for the TENSILE STRENGTH and the DIMENSIONAL STABILITY that improve papermaking wire-cloth.The size of extensibility also is decided by the final size of papermaking wire-cloth, but extensibility is excessive, will produce new high elastic deformation, influences the DIMENSIONAL STABILITY of final products.
In the HEAT SETTING process, in the time of to the papermaking wire-cloth warp direction stretching, broadwise will produce a certain amount of retraction.Therefore for guaranteeing the Stability Analysis of Structures of papermaking wire-cloth, in warp direction stretching, also apply tension force with control retraction speed and final relaxation shrinkage in the papermaking wire-cloth broadwise.Specifically be as follows with the relaxation shrinkage of the extensibility of warp-wise and broadwise as the control parameter:
Extensibility=(finishing length-initial length)/initial length in order to guarantee the stability with a kind of product, requires the extensibility of like products identical or approaching.
Relaxation shrinkage=(initial width-end width)/initial width in order to guarantee the stability with a kind of product, requires the relaxation shrinkage of like products identical or approaching.
The present invention is according to the hot shortness and the thermoplasticity of monofilament polyester or nylon monofilament, by papermaking wire-cloth is selected suitable heat setting temperature, vertically apply simultaneously tensile stress, product is extended at length direction, control the horizontal retraction of product simultaneously, make product structure change, eliminate stress, make product surface smooth, dimensionally stable.
The invention has the beneficial effects as follows:
Adopt the technology that from coil to coil quantitatively heats up and from coil to coil is quantitatively lowered the temperature, and in addition corresponding tensile stress, can under the uniform temperature condition, eliminate the internal stress that papermaking wire-cloth produces effectively in weaving process, repair and improve the imperfection structure of formation in the papermaking wire-cloth processing, improved the structural stability of papermaking wire-cloth.Method is simple for this, guaranteed the quality of papermaking wire-cloth effectively.
[description of drawings]
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the processing schematic diagram of the HEAT SETTING post-processing approach embodiment of papermaking wire-cloth of the present invention.
Among the figure, 1-papermaking wire-cloth, 2-cylinder, the last bellows of 3-, bellows under the 4-.
[specific embodiment]
As shown in Figure 1, use the hot air type heat setting machine that high speed wide cut three-layer paper making forming web is carried out the HEAT SETTING post processing, the warp and the parallel of high speed wide cut three-layer paper making forming web have adopted high pyrocondensation and high-intensity monofilament polyester and nylon monofilament, wherein the pyrocondensation value maximum of monofilament polyester can reach 13%～14%, and extension at break can reach 25%.
HEAT SETTING post processing specific practice is as follows:
(1) papermaking wire-cloth 1 being stitched into annular casing along warp direction makes papermaking wire-cloth 1 at the uniform velocity turn round with cylinder on two diameters of setting machine are 1.5 meters and the cylinder 2 that is parallel to each other, last bellows 3 and following bellows 4 opposites are provided with, bellows blow out hot blast to the papermaking wire-cloth that passes through simultaneously up and down, and this zone forms the hot blast thermal treatment zone.The set hot blast thermal treatment zone is 2 meters along the length of papermaking wire-cloth warp direction, and the width of width and papermaking wire-cloth is suitable, and papermaking wire-cloth 1 at the uniform velocity passes through in the middle of the thermal treatment zone continuously with 1.5 meters/minute.The length of passing through the speed and the thermal treatment zone of papermaking wire-cloth must guarantee papermaking wire-cloth can be in the thermal treatment zone full and uniform being heated.
(2) initial temperature of Heating air box is 80 ℃, and the papermaking wire-cloth temperature that turns around for every time rises one grade, reaches 195 ℃ up to maximum temperature.The way of specifically heating is bigger in every grade of amplitude of heating when initial temperature begins, and along with progressively increasing of heating-up temperature, temperature amplification is corresponding to be reduced, near maximum temperature the time, and the amplitude of heating minimum.Though because maximum temperature less than the softening point of monofilament, near maximum temperature the time, produces bigger irregular distortion for preventing papermaking wire-cloth, so will select the less amplitude of heating.It is 20 ℃ that present embodiment heats that the selection of amplitude begins, and the stage casing is 15 ℃, and back segment is 10 ℃.
The selection of maximum temperature will be with the structural safety of papermaking wire-cloth but can farthest be eliminated the papermaking wire-cloth internal stress is condition.Specifically, maximum temperature with near and to be no more than the softening point that has in the papermaking wire-cloth than the low softening point monofilament be selection principle, under a suitable maximum temperature condition, can reduce the internal stress of papermaking wire-cloth and don't the overall structure of destruction papermaking wire-cloth to the full extent by suitable stretching, make papermaking wire-cloth reach stable structure.
(3) in adding the HEAT SETTING last handling process, between two parallel cylinders, apply different tensile stresses according to different thermogrades, initial tension force begins with 2.5kg/cm, increase along with temperature, tensile stress also progressively strengthens, when reaching 195 ℃ of maximum temperatures, tensile stress reaches maximum 22.5kg/cm.This process is to realize by the tenslator of setting machine, its objective is the internal stress that overcomes fabric tissue inside to greatest extent, makes product structure stable, surfacing, dimensionally stable.
Keep papermaking wire-cloth when (4) reaching maximum temperature and on setting machine, continue revolution heating two circles in the thermal treatment zone, it is constant simultaneously to keep maximum tension 22.5kg/cm under the maximum temperature condition, and specific practice is that the tenslator on the heat setting machine is switched to the constant pattern of maximum tension of keeping.And then turn around according to every time, descend 60 ℃ thermograde of temperature reach about 60 ℃ up to temperature, and tension force also progressively drops in 60～80% scopes of maximum tension, finishes this HEAT SETTING last handling process thus.
In the actual production, for the monofilament of different performance, the revolution number of turns when maximum temperature also is not quite similar.Its objective is to make monfil under the condition that the best is heated, continue time enough, guarantee that the crystallization and the relaxation of fibrous inside fully carried out, help farthest improving and repair unstable structure in the papermaking wire-cloth, make final structure more stable.
When (5) the papermaking wire-cloth warp-wise being applied tensile stress, product produces a certain amount of retraction on width when length direction extends.Be the horizontal retraction of control papermaking wire-cloth, promptly papermaking wire-cloth laterally apply certain force of strain, the control product is the speed of retraction laterally, thereby eliminate stress, and makes the surfacing of product.
In the present embodiment, the variations in temperature in the above-mentioned HEAT SETTING process is as follows:
80℃-100℃-120℃-135℃-150℃-165℃-175℃-185℃-195℃-195℃-135℃-75℃。Wherein, one grade of the every variation of said temperature is that papermaking wire-cloth returns and turns around.
Table 1 is that the warp-wise tension force of present embodiment increases and the corresponding matching of variations in temperature concerns:
The corresponding matching of table 1 warp-wise tension force and temperature
After warp-wise tension force reached maximum tension, heat setting machine reduced tension force with automatic slowly, and tension force is in 60～80% scopes of maximum tension when HEAT SETTING finishes.
When papermaking wire-cloth (also being) under the maximum temperature condition under the maximum tension condition return take two turns finish after, the drawing mechanism of heat setting machine and tentering mechanism stop to continue to stretch and tentering simultaneously, thus fixedly the length of papermaking wire-cloth and width.Way one is in order to stablize the dimensional structure of papermaking wire-cloth like this, the 2nd, and the length of this moment and width are and finish length and finish width, are used to calculate the foundation of extensibility and relaxation shrinkage.
Therefore, the concrete control of extensibility is to finish by being provided with of maximum tension tension force.The concrete control of relaxation shrinkage is to finish by being provided with of horizontal retraction tension force.
Warp direction stretching rate in the present embodiment is 20%, and the broadwise relaxation shrinkage is 15%.
