Definitions

  • the invention relates to a method for the continuous improvement of the grip and surface of textile fabrics and knitted fabrics according to the preamble of claim 1, and to a device for carrying out this method according to the preamble of claim 10.
  • GB-A 2,158,472 shows a method and an apparatus for drying a textile web. The movement between the two web stores takes place practically without touching the channel connecting the two stores. This is to prevent mechanical stress and friction.
  • the object of the present invention is, in particular, to create a method by means of which a grip and surface improvement, that is to say a greater softness of textile fabrics and knitted fabrics, can be achieved.
  • the web removed from the second web store is subsequently subjected to the same treatment process at least once again. It is expedient if the material web to be treated is thrown against the respective impact surface at a speed in the range from 400 to 1000 m / min, preferably at a speed in the range from 600 to 800 m / min.
  • the web to be treated is temporarily stored in sections in at least approximately U-shaped web stores, the web to be treated and temporarily stored continuously introduces into the leg part of the first U-shaped web store, continuously alternating and in sections to the other, removes the second leg part, returns it in the opposite transport direction, removes it again and so on, continuously introduces the treated web alternately and in sections into the one leg part of the second web store, removes it again in the opposite transport direction, returns it to this and so on, and continuously takes the finished fabric from the other second leg part of the second U-shaped fabric store.
  • the invention further relates to a device for carrying out the method according to the invention with the features in claim 10.
  • the two web stores are at least approximately U-shaped and are preferably provided on their inside with optical scanning means for scanning their degree of filling with sections of the web to be treated, one leg of the U-shaped first web store for continuous, temporary , section-wise take-up of the material web to be treated and the other leg for continuously alternating and section-wise removal, return in the opposite direction of transport, new removal and so on, and the one leg of the U-shaped second web store for continuously alternating and section-wise pick-up, oppositely directed removal, re-picking and so on, and the other leg of the second web store for continuous removal of the treated web is formed.
  • the pneumatic conveying means assigned to the accelerating channel are divided into two pneumatic conveying means groups acting in opposite directions of the accelerating channel, and these two groups are alternately separated from one another via a preferably after the Principle of the Cuanda effect switching element, are connected to a compressed air source, these two groups alternatingly arranged on both sides of the acceleration channel, laterally offset to one another, obliquely directed to the web transport plane and arranged in their respective conveying direction in the end region of the acceleration channel.
  • the feed and discharge arrangement are designed to be independently controllable with respect to their transport speed.
  • the material web impact surfaces have a lattice structure and are curved outwards and downwards to accommodate a material web section thrown against it.
  • At least one shrink dryer is connected upstream of the first web store and / or the second Web store at least one shrink dryer is connected downstream. It is particularly advantageous for the treatment of plush and terry goods if the at least one shrink dryer for receiving and transporting the goods to be treated through the shrink dryer and for dispensing the goods emerging from the latter into the first web store or for receiving the goods from the second or last goods web storage goods is provided with a continuously drivable, air-permeable, endlessly circulating conveyor belt, which has an upper, stationary and air-permeable boundary wall to form a transport channel which is limited in the vertical direction at the top and bottom and serves to receive and support the goods to be treated vertically is arranged, which is penetrated by downwardly directed, transverse to the web conveying direction blowing nozzles, and that preferably viewed in the direction of goods pass B offset to the latter arranged below the upper run of the lower conveyor belt, preferably The upper run of the latter
  • the device shown has two approximately U-shaped web stores 1 and 2 for loosely accommodating one web section 3 'or 3 "each, and one arranged between these two web stores 1, 2, connecting them and in its longitudinal direction on its two end faces delimited by a web impact surface 4 and 4 'web guiding and acceleration channel 5.
  • This component 8 can be used on its own or as in the exemplary embodiment shown, for example with two shrink dryers 9 and 9 'arranged on the inlet side, the latter also serving as a feed arrangement 9' for the continuous supply of the web 3 to be treated into the first web store 1.
  • optical scanning means 10 and 10' are provided in the lower deflection areas of the two web stores 1 and 2 in order to fill the degree of filling of the two web stores 1 and 2 with sections 3 'and 3' 'of those to be treated Scan web 3.
  • the pneumatic conveying means assigned to the acceleration channel 5, as can be seen particularly in FIG. 3, are divided into two pneumatic conveying means groups (blowing nozzles) 6 and 6 'acting in opposite directions of the acceleration channel 5.
  • These two blow nozzle groups 6 and 6 ' are alternately separated e.g. connected to a compressed air source 12 via a flip-flop switching element 11 (see FIG. 2) which works on the principle of the Coanda effect.
  • the air used can have a temperature in the range of, for example, approximately 80 to 200 ° C.
  • the two shrink driers 9 and 9 ' are for receiving and transporting the goods 3 to be treated through the shrink driers and for dispensing the goods 3 emerging from the shrink dryer 9' into the first web store 1 provided with a common, continuously drivable, air-permeable, endlessly rotating conveyor belt 13, which is driven at a conveying speed of about 40 to 50 meters per minute.
  • the latter has an upper, stationary and air-permeable boundary wall 15 arranged to form a transport channel 14 which is limited in the vertical direction at the top and bottom and serves to receive and support the goods 3 to be treated. which is penetrated by blow nozzles 16 directed downwards and extending transversely to the direction of web conveyance.
  • the upper, air-permeable perforated boundary wall 15 has at least approximately the shape of a shed roof in a vertical section running longitudinally to the web transport direction (see in particular FIG. 4), with between two mutually adjacent angular sections 15 ', 15 ′′, 15 ′′ ′′, etc., each has a downwardly directed blowing nozzle 16, which are simultaneously designed to support the assigned sections 15 ′, 15 ′′, 15 ′′ ′′, etc.
  • the distance a between the upper blowing nozzles 16 and thus the upper boundary wall 15 supported on them is opposite the bearing surface b of the conveyor belt 13, e.g. adjustable in a range of approximately 10 to 80 mm.
  • two lower blowing nozzles 17, which support the upper run of the conveyor belt 13 and are directed upward into the associated angular sections 15 ′, 15 ′′, 15 ′′ ′′ etc. of the upper boundary wall 15, are provided between two upper blowing nozzles 16 .
  • the lateral horizontal spacing of the upper blowing nozzles 16 from one another is approximately 190 mm and that of the lower blowing nozzles 17 from each other is approximately 95 mm.
  • the upper and the lower, blowing air supplying blow nozzles 16 and 17 are each divided into groups and by switching means 18 can be connected to a hot air source 19 about 2 times per second in an alternating and pulsating manner.
  • the subdivision and switchover is designed such that each active blow nozzle group is opposed by an inactive blow nozzle group and the blow nozzle groups immediately adjacent to the side of an active blow nozzle group are inactive. In this way it is ensured that, alternately, a section of the goods 3 passing through a shrink dryer 9 or 9 ′ is always pressed down by upper blow nozzles 16 onto the bearing surface b of the endlessly rotating conveyor belt 13 and thus inevitably together with it by the corresponding shrink dryer 9 or 9 'is transported through.
  • the web 3 is pneumatically removed in sections from the latter with the aid of the nozzle arrangement 6, in the acceleration channel 5 to a speed of approximately 600 accelerated up to 800 m / min, depending on the type of goods, and at the end of this acceleration section 5 hurled against the grid-like and arched impact surface 4 and compressed there.
  • the lattice-like and thus air-permeable design of the impact surface 4 makes it impossible to form an air cushion that dampens the impact between the impacting web section and the impact surface 4.
  • the two pneumatic conveying means groups 6, 6 'on both sides of the acceleration channel 5 are mutually offset by the distance from one another by the angle y directed obliquely to the web transport plane, which means that a waveform is given through the acceleration channel 5 against the impact surface 4 to be transported 3 in the area of the active blow nozzle group 6 (FIG. 3 on the right), as a result of which the transport air in this area is extremely efficient at the area to be transported Goods 3 attacks and causes a very good transport effect on the same.
