No. 3,687,605. Furthermore, this document specifies further polymers or their precursors, which can also be used as component A, with the use of component B possibly being necessary.
- the resulting polymers must still contain free and / or blocked isocyanate groups in order to be suitable as component A. It is assumed that component A can react chemically with the wool of the fabric and / or with component B via the isocyanate groups, optionally after the isocyanate block has been removed.
- Products suitable as component A can be implemented, among other things aliphatic, alicyclic or aromatic diisocyanates with polyhydric alcohols Obtain oligo- or polyurethane. Known from polyurethane chemistry Chain extenders can also be used. Implementation to oligo- or Polyurethane is carried out with an excess of isocyanate equivalents, so that the Reaction product still has free NCO groups.

- aqueous composition containing both component A and component B contains and which is well suited for the method according to the invention is the product DICRYLAN® WSR from Ciba Specialty Chemicals Pfersee GmbH.
- the amounts of component A and component B, which in the invention Procedures on which the fabric or garment should be applied can be broad Ranges can be varied.
- the procedure is preferably such that the fabric is washed with an aqueous Fleet is treated that contains A and B. Following this impregnation, which e.g. can be done by immersing the fabric in the fleet, the fabric or garment squeezed or flung to remove excess moisture. Squeeze and centrifuging are preferably carried out so that the fabric subsequently has a liquor absorption of 10 to 80% by weight, preferably 30 to 60% by weight, based on the dry fabric before impregnation with the liquor.
- the tissue After squeezing or spinning, the tissue should be related to an increase in weight in the range mentioned on dried fabric before impregnation.
- concentrations in the Treatment liquors are preferably chosen so that after the Squeezing or spinning 0.25% to 2.5% by weight of component A and 0.05% by weight to 0.5% by weight of component B, preferably 0.5 to 1.8% by weight of A and 0.1 to 0.3 % By weight B. These values are in each case on dry fabric before the impregnation process based.
- a component B is used, it is preferably carried out in such a way that on the fabric after centrifuging and squeezing, a weight ratio of component A to Component B is in the range from 10: 1 to 3: 1.
- the moisture content of the fabric or Garment can be adjusted to 10 to 80 wt.%, Preferably 30 to 60 wt.%.
- a Moisture content in this area at the start of the pressing process is crucial Requirement of the method according to the invention. Especially those places where then the wrinkles are to be pressed in, a moisture content in the have the specified range. If, as described below, after spinning or Before the wrinkles are pressed in, other operations such as Toppers are carried out, the moisture content is adjusted after these operations.
- the stated values for the moisture content mean the amount of water which is on the fabric, based on the weight of that fabric after one Drying at 110 ° C for 30 minutes.
- the weight of the goods used as a reference is therefore the fabric dried under these conditions, on which component A and Component B, if any (with the exception of the ingredients used in the drying conditions are volatile). So the range mentioned for the moisture content is to be observed before starting the pressing process. Before it can be carried out the moisture content can be determined if it is not based on experience and Process parameters are already known. Depending on the conditions of the previous one Treatment, the moisture content may already be in the required range.
- the moisture content of the fabric or garment is already in the required area.
- the moisture content of the fabric before pressing based on experience known or it can be calculated so that a determination of the moisture content can be omitted. If the moisture content is already in the required range, then no corrective measures are required. Otherwise the required moisture content by adding moisture or drying. If dried for this is, this must be done under gentle conditions, so that chemical reaction of the Isocyanate groups is avoided.
- the tissue is clamped at two ends, e.g. a pair of pants on her top and bottom The End. Then the tissue is briefly heated with a stream of heated air or with treated with a mixture of water vapor and air.
- the tissue is briefly heated with a stream of heated air or with treated with a mixture of water vapor and air.
- the air which normally has a temperature of around 40 to 120 ° C and is dry the mesh. The purpose of this process is the surface of the fabric to smooth and so the subsequent pressing process, in which folds are pressed in facilitate.
- This topping process can be carried out after the application of components A and B if necessary and then squeezing and spinning off the tissue. It is advantageous to carry out the topping process so that the fabric or garment does not become dry, but still a moisture content of 10 to 80% by weight, preferably from 30 to 60% by weight. This is the range of moisture content that the Tissue in the subsequent pressing process must have at least those places where Wrinkles should be pressed.
- the moisture content that the fabric after the Toppern possesses can about the temperature of the heated air or over the duration of the supply this air can be controlled. Instead of blowing in heated air, you can also proceed in such a way that a mixture of superheated steam (120 ° C) and air is used at the beginning and then only air.
- an ironing process can be carried out on areas where later no wrinkles are to be pressed, e.g. to make seams on the inside the legs by hand. However, this should be done under mild conditions respectively.
- the subsequent pressing process in which folds are pressed into the fabric or garment requires that the fabric have a moisture content of 10 to 80% by weight, preferably 30 to 60% by weight. These values give the water content of the Tissue, based on dried tissue, as described above. The tissue must at least at the points where wrinkles are to be pressed in, a moisture content in have this area. Normally the fabric has a moisture content everywhere in this area.
- the process steps preceding the pressing process namely application of components A and optionally B, centrifuging or Squeezing, optionally topping and possibly ironing by hand, that the fabric after the last of these steps is already the one for the pressing process has the required moisture.
- the pressing process can be done without previous additional measures to increase or decrease the moisture content are carried out will.
- Wrinkles are pressed into the fabric or garment in the next process step, e.g. Creases for trousers or pleats for skirts.
- the folds can be in one earlier process step has already been preformed by applying a slight pressure be. But it is also possible to create wrinkles in a previously wrinkle-free tissue.
- the fabric is designed accordingly, so that the desired Make a fold is formed. This is now at a temperature in the range of 80 to 200 ° C, preferably 130 to 170 ° C pressed in using a pressure.
- the specified The temperature range does not represent the temperature of the press tool (which can be higher), but the temperature that the tissue has at the points where the folds are pressed, on the surface facing away from the pressing tool.
- the temperature of the tissue on the surface facing away from the pressing tool can be by means of a temperature sensor measured and controlled via the process parameters.
- the statement that the pressing process at a temperature in the range of 80 to 200 ° C, preferably 130 to 170 ° C, performed must be does not mean that the surface facing away from the pressing tool Tissue at the point of the fold during the entire pressing process a temperature in must have mentioned range. Rather, this surface only needs to be used sometime during of the pressing process have a temperature in this range.
- the tissue After pressing, the tissue must, as mentioned, where the folds are pressed have a certain moisture content. In the case of light colored, uncolored Fabric or in the case of fabrics with a low basis weight, it is often advantageous when the tissue is practically completely dry at the folds.
- the pressing process is preferably carried out in such cases so that the tissue or Garment handy where wrinkles are pressed after pressing is completely dry. Otherwise, the permanence of the wrinkle compared to washing processes be deteriorated. A complete drying of the fabric can be done in a simple manner Reach the duration of the pressing process.
- tissue is pressed in at the places where wrinkles are pressed after pressing is not completely dry, but has a moisture content of 10 - 70% of the moisture value (in% by weight) that the fabric has on it Set before the pressing process, but at least a moisture content of 5% tissue at these points (based on tissue weight at these points) having. This often results in undesirable optical effects on the surface prevent or at least weaken.
- a drying of the fabric except for the Desired moisture value can be easily over the duration of the pressing process to reach.
- the pressure to be applied when pressing the folds can be varied widely. He will expediently matched to the fabric properties and is preferably in the range from 1 to 10 bar. Commercially available apparatus are suitable for the pressing process, which allow to achieve the required pressures and temperatures.
- the duration of the pressing process must be at least so long that the fabric or garment at the points where folds are pressed in, after pressing, the desired one Has moisture content. This can vary depending on the type of fabric. A longer one Dwell time of the fabric in the press is not necessary in most cases, but can be an advantage in individual cases.
- the duration of the pressing process is normally about 5 Seconds to several minutes, depending on from the press tool.
- the fabrics can be dried in air at room temperature or at elevated temperature (eg in a drying cabinet) until they have reached equilibrium moisture. Subsequently, further process steps customary in the manufacture of ready-made goods can be carried out, including ironing by hand at the points where no folds have been pressed in.
- the tissue is without Apply a mechanical tension and without applying pressure for 5 to 30 minutes 130 to 200 ° C, preferably at 140 to 180 ° C, treated.
- the pants were then topped for 20 seconds by placing them on their top and clamped lower end, closed the lower openings of the trouser legs and in from above the inside of the pants first a mixture of saturated water vapor for 10 seconds (120 ° C) and hot air and then only hot air for 10 seconds.
- the pants became after the toppers turned and the side seams ironed on the inside.
- the pants were turned in a press.
