Definitions
- the invention relates to a method for compressively shrinking a textile fabric - in particular from woven or knitted fabric - on a rubber band shrinking system (with a fabric web to be shrunk between the elastic band and the shrink cylinder) for the purpose of setting a desired shrinkage value, the thread density of the fabric web passing through the shrinking system being measured and is regulated to a value which is essentially constant in the longitudinal direction of the web.
- a method of this kind is described in DE 43 23 715 C1.
- a feature of the known method is to regulate the shrinkage independently of the thread density of the incoming web so that the thread density at the outlet of the shrinking system is given a predetermined value that is the same everywhere. This result is known to be achieved by regulating the speed of the unit downstream of the actual shrinking machine in accordance with the deviation of the thread density from a standard value. When used, it turned out that the regulation of the speed of a machine element connected downstream of the actual shrinking assembly is not always sufficient to achieve a uniform thread density with sufficient compressive shrinkage.
- the invention has for its object to make the thread density of the fabric so controllable that sufficient compressive shrinkage and everywhere the same thread density of the fabric leaving the machine can be achieved even in extreme cases.
- the solution according to the invention for the above-mentioned method for compressively shrinking a textile web on a rubber band shrinking system, in which the thread density of the web is to be regulated to a substantially constant value, is that the contact pressure of the rubber band on the associated shrink cylinder is regulated.
- the rubber band - in the thread language also means: rubber blanket - should be pressed more or less strongly against the shrink cylinder.
- the tensile or longitudinal tension of the rubber band remains essentially constant, at least in the control according to the invention.
- textile material webs - both fabrics and knitted fabrics - can also be used with extremely uneven thread density of the incoming web and / or with extreme Shrinkage requirements are treated so that the goods shrink the machine sufficiently and leave with the same thread density everywhere.
- Fig. 1 is a schematic drawing of a compressive shrinking system for
- FIG. 2 shows a schematic drawing of a compressive shrinking system for
- a feed roller 1 with associated drive, a damping drum 2, a spreader field 3, and a rubber band generally designated 4 follow one after the other.
- Shrinking unit with drive 5 a felt calender 6 with drive 7, a cooling drum 8 and a combined tafler / winder 9 with drive 10.
- the actual thread density in particular the weft density in the case of woven goods, is measured with the aid of a thread counter 11.
- the thread counter 11 is spatially assigned to the shrinking assembly 4 in such a way that it measures the thread density on a section of the fabric web 20 transported in the direction of the arrow 12 following the shrinking assembly 4. According to FIG. 1, the thread counter 11 can continuously measure the thread density of the freshly shrunk fabric.
- the shrinkage capacity and the thread density of an untreated textile fabric are directly related. If the actual thread density varies in the longitudinal direction of the web after the treatment, the compressive shrinkage must be changed accordingly - in the sense of a compensation of the thread density in the longitudinal direction of the web or in order to adjust it to a target value.
- the contact pressure of the rubber band 13 against the shrinking cylinder 14 is changed or regulated in the shrinking assembly 4.
- the first guide roller 15 of the rubber band 13 in the transport direction 12 is made adjustable approximately radially with respect to the shrinking cylinder 14 in the arrow direction 16, that is to say transversely to the axis of the respective roller 15, with the aid of a corresponding transverse drive 17.
- the thread counter 11 when it determines an actual thread density deviating from the norm, gives a control pulse along a line 18 to the transverse drive 17 of the guide roller 15 of the rubber band 13.
- the guide roller 15 is moved in the direction of the arrow 16 ( adjusted in or against the arrow) and accordingly changes the contact pressure of the rubber band 13 on the shrink cylinder 14.
- the contact pressure of the rubber band 13 With an actual thread density measured in the thread counter 11, which is higher than a predetermined target thread density, the contact pressure of the rubber band 13 is relatively reduced.
- the actual thread density measured in the thread counter 11 is lower compared to the nominal Value the contact pressure of the rubber band 13 increased relatively.
- a control element 19 can be switched into line 18.
- the web of fabric 20 has a lower shrinkage capacity / requirement than the specimen defining the target value, because of the higher thread density, while in the other case, because of the lower actual value of the thread density compared to the specimen, the web area in question has a relatively high shrinkage capacity.
- the fabric web 20, which is shrunk according to the invention and set to a thread density that is the same everywhere, is either rolled up onto a bale 21 or stacked onto a stack 22.
- Fig. 2 shows a compressive shrinking system, which is preferably used for the treatment of knitted fabrics.
- the same or corresponding parts are designated in FIG. 2 as in FIG. 1.
- the feed roller 1, a damping drum 23, the rubber band shrinking unit 4 and a heating drum 24 with drive 25 and finally a discharge combination designated as 26 follow one after the other, which adapt to the technical requirements taking into account the easy stretchability of knitwear is.
- the fabric web 20 is partly passed over a conveyor belt 27 in order to prevent it from stretching unnecessarily.
- the fabric web 20 runs on a bale 29 in a two-roller riser dock 28.
