Definitions

  • the invention relates to a method for the continuous application of liquor, preferably of finishing liquor, to absorbent and compressible material webs, in particular fiber webs, e.g. Textile webs. It also relates to devices for carrying out the method.
  • the present invention relates to a method in which such an amount of liquor is applied all at once or in succession that the maximum determined by the absorbency of the substrate absorbable amount is not reached, but the total amount applied is above the water retention capacity of the substrate. Methods in which the maximum achievable amount is applied and the excess is removed again, in particular padding, are not part of the invention.
  • web encompasses a textile structure capable of absorbing liquids, the length of which is very great in relation to the width, for example about 500 to 10,000 times, and with a thickness that is usually between one and ten times the diameter of the threads that make up the textile.
  • the term therefore includes knitted fabrics, other nonwoven webs such as nonwovens and also sheets of parallel warp threads that are to be sized or, for example, dyed before weaving. In these cases, the thickness of the web can also be greater.
  • Examples of such processes include padding, splashing, the various methods of impregnation, spraying, spotting the liquor, applying foam and printing; in many cases it is necessary or inexpensive to first apply the excess and then remove the excess.
  • An important example of the latter method is padding, in which the textile material web is basically offered as much liquor as it would like to take up, and the excess of liquor removed between squeeze rollers. It is not possible to remove more liquor than the so-called water retention value, which is determined according to the DIN 53'814 standard. At technically reasonable squeeze pressures, the remaining amount of liquor is above this limit. Without squeezing, the amount of liquor applied, also called pickup, cannot be regulated.
  • MA minimum order
  • W2 / 150 + 40 the amount of liquor in% by weight that lies between zero and a value given by the expression (W2 / 150) + 40, where W is the water retention capacity mentioned.
  • the upper limit is 10 to 30% by weight below the limit of the squeezable excess.
  • the dosing roller order accordingly includes all application quantities that lie between the value of W and the saturation value of the substrate.
  • the invention has now set itself the goal of eliminating the disadvantages described above and to provide a method which makes it possible in a simple manner to distribute the liquors applied to an absorbent web material uniformly therein, the distribution effect being controllable and no squeezing of fleet occurs.
  • CH-A 530 230 it is mentioned casually that the even enforcement of the textile goods with the finishing fleet can be promoted in particularly unfavorable cases by special measures, including mechanical measures such as squeezing mechanisms.
  • the cited reference is, however, only the minimum order, in which, in unfavorable cases of the distribution of the fleet, the use of squeeze units Can accelerate distribution.
  • the uniformity of the distribution is a characteristic of the minimum order, and therefore the application of the squeeze units to the uniform distribution of fleet quantities which comprise a squeezable excess cannot be transferred.
  • Squeezers consist of a cooperating pair of rollers, in which at least one roller has a rubber-elastic surface or is made entirely of rubber.
  • the material web is passed between the two rollers and clamped.
  • a squeezing effect arises from the fact that the two rollers are pressed against one another, the elastic surface of the rubber roller flattening out and a squeezing effect being exerted as a result.
  • a regulation of the squeezing effect is, analogous to the foulard, only possible within very narrow limits. It has been found that such a squeeze mechanism is not suitable for the purposes of the invention.
  • controllable compression is that only a redistribution of the liquor takes place inside the material web, in particular by bringing fibers or fiber areas which contain excess liquor quantities into intimate contact with those areas where there is a fleet deficit without that the fleet is squeezed out of the material web.
  • the invention represents a new, universal concept that provides a quick, uniform and controllable impregnation with liquor and can be followed by any application method, the uniformity of which is insufficient.
  • the new process brings great advantages to spray technology, which is elegant in itself but always results in a non-uniform application.
  • a preferred application of the invention is in connection with the metering roller application method.
  • the compression of the material web in the leveling unit is achieved in that the web is passed through a gap, the thickness of which is set between zero and the thickness of the web entering the leveling unit.
  • the setting of the thickness of the gap depends on several factors, the goal always being the bare one Redistribution, ie equalization, of the fleet inside the material web must apply. The most important factors are the compressibility of the web containing the fleet, its thickness before it enters the leveling plant, and the content of the fleet. Other factors are the physical properties of the fleet and material web as well as the degree of non-uniformity of the fleet order.
  • the textile web to be impregnated is first conveyed, as usual, by a delivery plant. This consists either of two rolls with a nip through which the textile web is guided, at least one roll being driven, or of a driven roll with a non-slip surface which is wrapped around at least 180 °.
  • the web then arrives at the fleet applicator either directly or via guide, balancing and / or spreading rollers.
  • the preferred fleet order unit which can also be present twice or more, i.e. the metering roller application device is either the MA application device known from the above-mentioned US Pat. No. 3,862,553 or its new development, which forms the subject of EU-A-0137089. From the disclosure of these two publications, the construction of the devices and their functions as well as the operating method are apparent in every detail.
  • the method according to the invention can also be carried out with other application works which are known to the person skilled in the art. Foularding with squeezing of the excess fleet is out of the question.
  • the selected order method can deliver an uneven order, but constant streaky unevenness over the length or width should be avoided.
  • the gap required in the leveling plant can be achieved in various ways. Usually the gap between two rollers is set by which one should be provided with a rubber-elastic surface or be made entirely of rubber. This roller is driven. The other roller should have a harder surface and can also be driven.
  • one roller is brought closer to the other. This is best done with a screw drive. Additional devices are preferably provided to quickly lift one roller from the other so that web tears are prevented when seams or other thick spots run in. This quick lifting can be effected by a hydraulically operated toggle lever mechanism, for example. Such constructions are known to the person skilled in the art.
  • the hard roller is provided with heating or cooling means.
  • Means can be provided to apply steam to the web from the outside in order to avoid liquor evaporation when the roller is heated.
  • the gap can also be formed by two solid surfaces, which face each other at a short distance and are preferably provided with an elastic covering, the surface of which has a low coefficient of friction.
  • leveling units can also be provided in succession.
  • rollers In leveling units with rollers, these can be installed in any arrangement; the plane in which the two roller axes lie can therefore be horizontal, vertical or any inclination.
  • the web can also wrap around one or both rollers at any angle.
  • the material web After leaving the leveling unit, the material web is further processed as usual by generally transferring it to a continuously operating dryer, in particular a tenter. This is equipped in a known manner with the usual auxiliary devices. Finally, the web is wound up.
  • the invention now makes it possible to eliminate non-uniformities which have often been observed when using the known application methods and which have hitherto either been accepted or had to be avoided by using other, more complicated methods.
  • two or more fleets can now be applied in succession, which are not stable when mixed and are mixed and evenly distributed in the web material itself.
  • FIG. 1 A preferred embodiment of the device according to the invention is shown in FIG. 1 shown very schematically.
  • Auxiliary devices such as circulation and feed pumps, fleet tanks, machine frames, motors, control and regulating devices are not shown or are not shown in detail; they are known to the person skilled in the art.

  • the supplied textile web 20 which comes, for example, from a lug 18, wraps around the driven delivery roller 12, which is provided with a non-slip coating, at approximately 220 °. It then reaches the web tension compensation via a deflection roller 11 to a dancer roller 10.
  • the web 20 passes through the measuring apparatus 28, 28 ⁇ measuring the web thickness without contact and indicating the square meter weight, and then it is optionally fed to a group of arch rollers 24 which are used to smooth the textile material and to the Spread out wrinkles. They are usually required for knitwear, but are usually not necessary for solid fabrics such as shirt fabrics.
  • the material web 20 then arrives at the application unit 22, which can be of any design and produces a more or less uniform, controlled liquor application, the amount of which lies between the value of the water retention capacity of the substrate, determined in accordance with DIN 53,814 (in accordance with ASTM-D2402-65T or SNV 98592 ), and the saturation value.

  • the Level sensor 40 can be of any design. For example, he can sense the level through surface contact, he can work on the basis of electrical, magnetoelectric (Hall effect) or reflective variables (light such as infrared or laser light, other rays such as beta or gamma rays, soft X-rays, corpuscular radiation). It is preferably constructed and arranged in such a way that it periodically senses across the width of the web 20, for example with a sampling frequency of a few hertz.
