Description

The method and apparatus that is used for fabric calendering

Technical field

The present invention relates to be used for the method and apparatus of fabric calendering.

In textile field, term " calendering " is meant a kind of ornamenting processing, in this ornamenting is handled, reduces its thickness thereby fabric stands hot-stretch, eliminates any possible fold and form tendentiousness bright looking (tendentially) at least one face.

Background technology

There are three kinds of calendering systems in the known technology, that is: a) watt formula (shoe) calendering, b) roll-type calendering and c) the belt calendering, preferably, optionally use above-mentioned calendering system according to the needs that use tradition and fashionable dress market for different textile field (synthetic fiber, string, reach animal fiber).

As being schematically shown among Fig. 1, in the system of the first kind, the cylinder 1 of heating is with respect to 2 rotations of fixing recessed die shoe, and this recessed die shoe 2 compresses this cylinder itself, and fabric 3 to be processed is arranged between this recessed die shoe and the cylinder.Described technology is mainly used in the field of wool fabric, and exists because the existence shortcoming of this fabric of stretching that rubs between the fixed surface of fabric and die shoe.This machine is single-acting, and only obtains above-mentioned effect on a surface of the fabric of handling.

As shown in Figure 2, rolling press or " cotton thread calender " and aforementioned two or more rollers or cylinder 1a, 1b, the 1c of differently being provided with, these rollers or cylinder are arranged on the top of each other, promptly pile up by " tower " formula, wherein at least one this cylinder (the cylinder 1b in the example shown) is heated, and these cylinders rotate relative to each other with very high pressure, and fabric 3 is arranged between these cylinders.Cylinder can be made by metal etc., is coated with various materials on it, and the general character of these materials is all to have high rigidity in any case.The feature of above-mentioned high rigidity can limit the distortion in the cross section, contact point place between the cylinder, and therefore this pressure is concentrated in the very little space.This machine can be single-acting or for many dynamic formulas, but related fabric to pass through direction always identical with surperficial (with respect to thermal source).

The implementation result and the result of the belt calender of just introducing are similar to a watt formula calender recently.In this technology, be schematically shown as Fig. 3, fixedly die shoe by deformable and whole impermeable be with 4 to substitute, be with 4 to constitute endless belt, guide and bear specified tension force by roller 5.By this way, different with the situation of traditional watt formula calender, significantly stretching can not appear in fabric.This machine is single-acting, and only obtains above-mentioned effect on a face of handled fabric.And the processing of impermeable band calendering also has an important auxiliaring effect: the moisture content that exists on the fabric or introduce at the enclosed environment that is exposed to heat (promptly, space between cylinder and the band) produce steam in the time of in, and described steam has fabulous effect for the technology of many textile materials.

As already mentioned, in all aforementioned known calendering technologies, main purpose is that the distribution by heat energy makes the thickness of fabric reduce significantly that (" laterally " speech is interpreted as typical implication in the textile field at this via horizontal mechanical pressure, promptly, the larger side face or the surface that refer to fabric claim " preceding " and " back " in the jargon).

For second effect of no less important, the fabric of processing need have significant surface to be changed, and makes fabric become like this and obviously has gloss.Yet the effect of this aspect of looking for sometimes according to fashion trend in vogue but is very temporary transient with unsettled.

In order to address this problem and form permanent bright looking, need to use follow-up stable operation or during the carrying out of this technology self, use chemical products to assist.In the belt calendering of all above-mentioned use chemicals, though the fuel factor of prolongation today as if all to the formation (development) of chemical products and forever remain on and have sizable effect on the fabric.

The present invention is based on and recognizes the following fact, that is, there is technical limitations in the calendering system of above-mentioned routine, and this has stoped the actual effect of this system.

Thus, it has been generally acknowledged that fiber and fabric are the materials of " having memory ", if these materials are let alone freely to relax (mode of nature or experience mechanical stroke), then be tending towards presenting the inactive state approaching as far as possible phenomenons such as (occur that fabric threads is curled, torsion of fibers is lax) lax, the moisture expantions of stress that machinery applies in various technologies with the original size state.

Therefore one of purpose of textiles ornamenting is to use a series of machinery, physics and the in a certain respect characteristic of chemical treatment with relative permanent mode fixed fabric.No matter be for for the structural class or for the visual appearance of fabric, calendering is a kind of accurate, tendentious stabilized treatment, and in calender process, thickness reduces with the sense of touch aspect particularly important.

In order to obtain these results, need in the traditional textile technology fabric of handling is applied various forms of energy simultaneously, especially cause structurally-modified mechanical action by extrusion, be used to supply the heat that makes fiber molecule easier stable institute energy requirement under new situation action but also need apply.In many situations, particularly for for the animal fiber of wool, apply simultaneously more or less high concentration moisture content or chemicals to strengthen effect.

This mechanical energy and heat energy have a kind of effect, and this effect directly depends on the time of staying of the effect that applies the required time of described energy, applied and the type that described energy discharges the inverse process of (thermal shock).So in practice, have the phase I, promptly " heating " time is the structurally-modified stage subsequently, promptly " just changes " time, and the inherent structure of this fabric presents new state in this stage.After this modification stage, at least for many materials, need to carry out cooling stage, i.e. " negative change " time, this stage must be fast and is thorough, thereby prevent to obtain in positive fringe time structurally-modified is because aforementioned fibers memory effect and disappearing to a great extent.

In watt formula calendering, the specified pressure on the fabric is moderate, and the time that applies is short.In addition, this fabric is exposed to air, but this means the moisture content rapid evaporation that contains in the fabric, and meets with stresses by stretching, extension.That the result is that this physical transformation has is strong, be very easy to the interior poly-component that disappears.

On the other hand, in the roll-type calendering, should (these) pressure higher, and be to obtain by the high hydraulic pressure that acts on the semi-rigid cylinder made by ply of paper (paper wool) or polyamide (hardness be about 85 ° of Shore D-be equivalent to 98-100 ° of Durometer A hardness); Temperature even can surpass 200 ℃, but the time that applies is very short.For those reasons, described technology can ad hoc be used for fabric that temperature is had high sensitive and has low hysteresis, synthetic fiber for example, or mechanically deform had high sensitive fabric, for example string.In any situation, only the obvious flat part at fiber can obtain appreciable and permanent result, can be loose yet self have the major part of the fiber of three-dimensional structure, and present significant metal visual appearance and " sensitive paper " haptic effect.

At last, in belt calender, processing time explicitly ground has prolonged, but the moderate relatively (1-5kg/cm of specified pressure ²The distribution average pressure), according to producing the power (pressure peak is the twice of distribution average pressure) that arc distributes in this belt calender of winding angle between band and the cylinder.The common anti-permeability of band makes can control water content, and in the practice, above-mentioned anti-permeability can prevent continuous evaporation and keep the constant of water content in whole technology.For those reasons, this technology is specially adapted to handle animal fiber.

As mentioned above, can use chemical products in this case; Because chemical bond well known by persons skilled in the art, this chemical products makes fabric form significant bright looking, sometimes according to the requirement of fashion trend and " plasticizing ".

Yet, use aforementioned chemical products to have three major defects in a large number:

-this chemical products and institute's use amount corrode this fabric itself pro rata, and fabric is died down;

-this chemical products itself and steam thereof corrode machine part, particularly are coated with the band and the hanging structure of silicone, shorten the life-span of calender significantly; And

-chemicals has cost, and this cost increases with the production cost that the loss in advance of machine part causes carrying out the fabric of this technology.

The method and apparatus that is used for the continuous treating fabric is known, and wherein when handling, what fabric was operated is the water blocking tape that bears high tension.For example, a kind of method that is used for continuous decatizing (decatization) has been described in the document WO-93/17167, it comprises makes and to pass the pressure apparatus that is made of the aforementioned water blocking tape that bears tension force by treatment fluid dipping or moistening fabric, and this water blocking tape clips cylinder in heating with fabric.

Fabric is under the mechanical constraint that pressure applied that is in by water blocking tape, in wet/wet environment, keep this fact of special time can cause the modification of the inherent characteristic of fabric in specified temp following time, thus on fabric, form be structural property may be again the permanent characteristics of visual property.

The existence of this water blocking tape produces following problems, and for for the defective that fabric treating produces and for the use resistance in time, described band all can produce integrity problem.In addition, use water blocking tape can cause very high replacement cost, and extremely complicated and heavy possible replacing operation.

Summary of the invention

The purpose of this invention is to provide a kind of equipment and method, it can be eliminated above with reference to described problem of prior art and defective.

Another object of the present invention provides a kind of method and apparatus of fabric calendering, it compared with prior art, can on the visual appearance of structural class and fabric, obtain improved, continuous permanent stable effect, and when the fiber of fiber that is used to handle synthetic fiber, plant origin and animal origin, not have what difference.

Another purpose of the present invention provides a kind of method and apparatus of fabric calendering, and it is designed to guarantee higher processing speed.

A further object of the present invention is, particularly for the auxiliary situation of utilizing chemical products to carry out calendering, can reduce the consumption of chemical products, and adopt make and safeguard aspect require the more short operation time and the parts of lower operational cost more.

In order to realize described purpose, theme of the present invention is the calendering method with feature of claim 1.The supplementary features of this method are recorded among the dependent claims 2-10.

Theme of the present invention also comprises the calendering equipment with claim 11 and dependent claims characteristic specified thereof.

Basic thought of the present invention is following initial intuition, promptly by the following manner effect of the conventional water blocking tape of (if not more effectively then comparably) acquisition comparably: the relative cylinder with strain surface of second operating unit is radially promoted, contact to compress with corresponding heated roller, form at least two zones of strong extruding thus, fabric bears the significant mechanical constraint that the pressure by relative cylinder produces via described zone.The mechanical constraint that applies in described zone can be significantly greater than the mechanical constraint that obtains in same zone by the water blocking tape that uses conventional tensioning.Certainly, the quantity in described zone depends on the mutual pressure of the cylinder of contact.In order to improve the productivity ratio of equipment, described zone can be repeated repeatedly.

Operating procedure is integrally considered (mechanical effect adds fuel factor) in addition, experiment shows: compare with the situation of belt calendering, effective and strong mechanical/thermal effect itself can produce surface of good light grade, it is better than the surface-brightening grade that obtains by traditional handicraft, and advantageously, in order for good and all to fix this brightness effect, a spot of chemical products is promptly enough.For the situation of particular web, in fact, what is called " KD " fixation wool technique for fixing of steam (that is, by) of not adding chemical products is enough to obtain the gloss of desired grade.

Describe the present invention referring now to accompanying drawing, this accompanying drawing is nonrestrictive example fully, and in the accompanying drawing:

-Fig. 1, Fig. 2 and Fig. 3 are respectively the schematic diagram that shows known watt formula calendering technology, known roll-type calendering and known belt calendering;

-Fig. 4 is the schematic diagram according to continuous calendering production line of the present invention; And

-Fig. 5 is the schematic diagram according to the possible modification of continuous calendering production line of the present invention.

The specific embodiment

Fig. 4 is according to the equipment of the continuous calendering of the fabric of first embodiment of the invention or the schematic diagram of production line.This calendering production line represents with Reference numeral 10 that on the whole it comprises the operating unit of following vicinity:

-moisture content control module or fabric adjustment unit 20, be provided with the device 28 and a pair of cylinder 24-23 that are used for the moistening device of control surface 27 and/or are used to use the chemical products dipping, this may be heated cylinder, and fabric is located at this subsequently between the cylinder;

-with the calender that Reference numeral 30 is represented, it has two pairs of motor-driven cylinders that pile up by the tower shape; And

-possible drying and cooling device, it is located at the downstream of second calender 30, because this possible drying and cooling device are conventional, thereby not shown in the drawings.

In production line 10, processed fabric 3 scrollings leave corresponding feeding means, by being pulled and being directed in the adjustment unit 20 with Reference numeral 12 known devices that represent, own on the whole, wherein this feeding means piles up the bearing 11 that fabric is arranged on it in the example shown.After adjusting in adjustment unit 20, fabric 3 enters calender 30 experience short stroke in air after, and specially the known devices of use own is drawn and guided.The fabric 3 that leaves calender 30 enters possible drying and cooling device (not shown) subsequently, and finally be pulled and guide to common stackable unit 16 by known devices 15 own, this stackable unit 16 is deposited in fabric 3 on the suitable accumulation bearing of representing with Reference numeral 17.

Adjustment unit 20 can be used for comprising all application scenarios that make water or chemical fixation product.

As mentioned above, experience is fixing by fabric drying and in other finishing process subsequently handles, and can realize the calendering of broad sense thus.Yet natch, in this technology itself, strengthen bright looking and permanent this bright looking that keeps, can obtain according to optimum of the present invention by adding a spot of water or product.

Adjustment unit 20 can be advantageously as inlet calender (entry calender).This calender comprises structural member 21, and this structural member 21 supports two

cylinders

23,24 with parallel axes, and at least one of these cylinders preferably (but nonessential) is heated.The Pneumatic pressure of at least one cylinder 23 by not being shown specifically promptly by pneumatic actuator, is pushed to another cylinder 24.The principal character of

cylinder

23,24 is corresponding with the feature of the cylinder of the calender 30 that hereinafter will describe.

Above-mentioned configuration can be advantageously used in the dipping of finishing fabric in first compacting (pressing) step, the variation that produces vision and tactile results subsequently.

This moisture content amount must remain higher before entering into two processing regions between the cylinder 24-23.For this purpose, fabric must be tending towards entering along the direction vertical with extrusion axis (being vertical direction in this example) (being horizontal direction in this example).

The inclination that faces upward or downward that surpasses 20 ° can cause moist fabric to touch surface heated to possibility, one of them cylinder prematurely.In fact this contact will cause the unexpected evaporation of moisture content and/or chemical products, and can significantly reduce the general effect of this technology like this.

Calender 30 comprises structural member 31, and this structural member supports at least two

cylinders

33,32 with parallel axes, and preferably is stacked on the two couples of cylinder 33-32 and the 35-34 of top of each other by the tower shape, and at least one cylinder in the described cylinder is heated.Each by Pneumatic pressure, promptly is pushed to another cylinder by pneumatic actuator (be not shown in detail among the figure, but those skilled in the art may appreciate that) at least one cylinder in the cylinder.Make relative position between the axle that can adjust cylinder if desired to actuator devices supply air, thereby make and can between the cylinder self at edge arbitrarily, pass through, even thick edge, or the fabric component of projection.It should be noted that above-mentioned in traditional calender two cylinders are packed together mutually by hydraulic actuator in this traditional calender by existing problems, this feasible position that can't adjust between the cylinder.

Preferably, be to make that the pressure of the every linear centimeter of 20kg acts on the fabric 3 at least, thereby obtain tangible drawing effect by the pneumatic actuator applied pressure.Each preferably is coated with among cylinder 33-32 and the 35-34 at least one and is suitable at high temperature working and hardness is not higher than 95 ° material of Durometer A hardness.Like this, can obtain the sufficient elasticity areal deformation of this coating, thereby between cylinder, form nip region, the rigidity of this nip region is lower and time suppression is longer, thereby making can not destroy fully to be present in " three-dimensional " structure in the fabric, and makes fiber keep special time under heavy mechanical constraint, in enclosed environment and do not have any evaporation.

Can be set selectively and be preferably in by each temperature between two cylinders among cylinder 33-32, the 35-34 time in 80-200 ℃ the scope.In addition, each can be adjusted by selectable mode the pressure between two cylinders in the cylinder.For this purpose, calender 30 can be equipped with unshowned regulator, and this regulator will can tune to up to the pressure that surpasses 100kg/cm and act on one or more pneumatic actuators of this unit 30.

In one embodiment, cylinder also can have different case hardness: for example, this can realize by apply rigid polymer, rubber or silicone at least one cylinder, so that maximum specified pressure concentrates on the minimum contact point between the cylinder.

Because the characteristic of calender by this calender 30 time, can produce stronger extruding to fabric 3 on the contrary.

Note, the device 28 that is used for the moistening device of control surface 27 and/or is used to flood of adjustment unit 20 makes the sense of touch of various types of fabric and gloss significantly strengthen, and this fabric is for example for to humidity or to owing to applying the particularly responsive animal fiber of steam that heat energy produces.It should be noted, in traditional roll-type calendering system, do not design such moistening stage.

As mentioned above, the specific function of calender 30 is, tendentiousness but the nonessential extrusion process of fixing this fiber continuously.According to principal character of the present invention, described calender 30 is not used water blocking tape, but as can be seen, specific calender roller also may have different morphotropism to 32-33 and 34-35, wherein under the situation that maintains horizontal mechanical constraint, and the right transverse pressure surface of this calender roller presents strain to fabric 3 by this calender roller.

Each of calender 30 can randomly be heated the cylinder among cylinder 32-33 and the 34-35, and as has been described, because each cylinder relativity shift radially, being in contact with one another pressure and can optionally changing between each cylinder, said circumstances is not shown, but it is known by those skilled in the art.

Being associated with two couples of cylinder 32-33 and 34-35 is respectively to organize delivery roll, for example respectively organize delivery roll with what mode shown in Figure 4 was arranged, it is designed to be used for determining the path of the near linear type of fabric 1 when passing through each to cylinder, promptly with the surperficial tangent of described delivery roll, therefore basically on the surface of described delivery roll.

Like this, the fabric 3 by this calender 30 under by the demarcation mechanical constraint that pressure applied between cylinder 32-33 and the 34-35, under specific temperature, be extruded the short time.With regard to the area load on putting on fabric 3, this mechanical constraint can be significantly higher than the mechanical constraint that obtains on same area when using water blocking tape conventional, tensioning.

Effect and productivity ratio in order to improve this equipment can adopt various solutions; For example, calender 30 can be two, and one of them calender is shown in the Reference numeral 30a among Fig. 5, perhaps even can be a plurality of; In this case, for example sequentially be placed with many cylinders and relative cylinder to heating along the progress path of fabric 3.

In addition, each of calender 30 can be driven by single motor-driven or by motor-driven independently cylinder 32-33,34-35, and in this case, before or after each is to cylinder, have make things convenient for system (convenient system) so that the right speed of described cylinder and before cylinder to or afterwards the right speed synchronization of cylinder.

The actual test that the applicant carries out is empirical tests: by the form of energy and the balanced proportions between the required time, method and apparatus according to the invention can realize the purpose of being scheduled to effectively, and does not have any significant termination with the appreciable impact effect between various passing through.For this purpose, must emphasize the time aspect according to technology of the present invention, above-mentioned time aspect is interpreted as applying institute's elapsed time between the various forms of energy.The exercises of heating, extruding and cooling are subsequently finished according to time sequencing fast: like this, the fabric relaxation response that after first action, causes owing to aforementioned memory effect become remarkable before, apply new action.It should be noted that the mechanical system of use known type is handled fabric and can't be obtained such operator scheme, the mechanical system of this known type typically is single-acting and needs the significantly long operating time.

Described method and apparatus can be defined as general, because above-mentioned method and apparatus can obtain favourable result when dried, the wet and/or moistening processing that is used for fabric, no matter this fabric is synthetic fiber, string or animal fiber.

Wet calendering of carrying out according to the present invention or dipping calendering can realize the natural brightness effect of highly significant, and the amount of therefore comparing required chemical products with belt calendering technology has reduced.The material of cylinder is compared more durable and insensitive with the silicone material of band, and compares with belt calendering system in addition, and required cost and the time reduces significantly when the production of cylinder and replacing.

Obviously, those skilled in the art can know in this many distortion by described equipment of example and method.For example, calender 20 can also comprise two pairs or more with

cylinder

23 and 24 similar calender rollers.

Certainly, structure and the details of embodiment can be with described herein different with example that illustrate, but do not deviate from the scope of the present invention that defines as appended claims.Therefore, for example can not use elastic material coating, but, obtain the strain of relative cylinder or each

relative cylinder

33,35 thus by making whole cylinder by this material such as silicone.
