Definitions
- the invention relates to a process for treating a fabric which contains from 30 to 100% by weight. made of wool.
- this fabric is in the form of a ready-made garment like a pair of pants or a skirt.
- Clothes such as skirts or pants are often wrinkled for fashion reasons desired, in the case of pants, for example, creases. Such wrinkles can be through Achieve pressing operations. It is known, for example, creases in ready-made pants, which wool fabrics contain, by pressing the dry pants at elevated temperature train. The disadvantage of such produced in this way creases is that they may be sharp after being pressed in, but after a few washes, often lose their shape already after a household wash. The permanence of such Creases compared to washing washes in wool washing programs (30 ° C) so lets much to be desired. The consumer is therefore forced, after each Laundry or after a few washes to iron the pants again.
- US Pat. No. 3,687,605 describes a multi-stage process for treating woolen fabrics to produce wrinkles.
- the fabric is treated with a polymer or prepolymer and then subjected to a curing process for the purpose of so-called external stabilization, in which drying of the fabric takes place. It is then treated with a reducing agent, then shaping takes place, for example, in the production of creases. To obtain optimum results, the fabric must be moistened with water before pressing the creases. Finally, a further temperature / curing treatment is required to re-form the reductant-cleaved chemical bonds in the wool fiber.
- This multi-stage process is relatively expensive.
- the object of the present invention was to provide an improved method which makes it possible, in fabrics consisting of 30 to 100% by weight of wool, to create wrinkles at desired locations, which provide improved permanence Have washing processes, especially in tissues, which in form prefabricated Clothes are present.
- the problem has been solved by a method for treating a tissue that is at 30 to 100 wt.% Of wool, wherein applying to the fabric a component A in the form of an aqueous composition, a Moisture content of the fabric of 10 to 80% by weight, preferably 30 to 60% by weight, adjusted and then at a temperature in the range of 80 to 200 ° C, preferably 130 to 170 ° C, presses wrinkles into the tissue, the tissue in the period between the Application of component A and the pressing of wrinkles not completely dried wherein component A is a compound containing at least two isocyanate groups in the free form or blocked by means of ketone oxime or hydrogen sulfite form present, or is a mixture of such compounds.
- the fabrics are preferably in the form of prefabricated garments, in which Wrinkles should be generated and / or stabilized.
- the garments may e.g. Be skirts, in which pleats are to be generated and / or stabilized. This is particularly suitable inventive method for producing creases of high permanence in pants.
- Tissues which are suitable for the process according to the invention consist of 30 to 100 % By weight of wool. 0 to 70% by weight may be made of other materials such as e.g. Polyester, polyamide, cotton. Lycra is also suitable as a mixing partner.
- As a wool component of Tissue can serve sheep's wool of any provenance. Their quality is not critical As far as the feasibility of the method according to the invention, but of course the Quality of the final article influenced by the wool quality.
- the articles obtained after carrying out the process according to the invention have better properties when the process is carried out on fabrics whose aqueous extract has a pH of about 6 to 10.
- the pH of the tissue to be treated is tested by extracting a sample of the tissue with water. If the extract has a pH outside the abovementioned limits, which may be due to the pretreatment of the fabric, eg the dyeing process, then it is advisable to treat and dry the fabric or the finished garment in an aqueous bath, before carrying out the method according to the invention.
- the bath used for this purpose is, for example, an aqueous solution of NH 3 , Na 2 CO 3 or NaHCO 3 .
- the treatment of the tissue can be performed by immersion in the bath at room temperature for a period of 10 to 30 minutes. The subsequent drying can be carried out in air from room temperature to equilibrium moisture content.
- the thickness and construction of the tissues on which carried out the inventive method are not critical and can be varied widely.
- the conditions of the method according to the invention such as temperature, residence time and pressure during pressing on the characteristics of the used fabric, which is possible by a few routine experiments. So In general, thicker fabrics require higher pressures and / or residence times during pressing the wrinkles are thinner.
- the process parameters to the Tissue properties to comply with the above and in claim 1 conditions.
- a Component A on the tissue or garment to be treated In a first step one brings in carrying out the method according to the invention a Component A on the tissue or garment to be treated. It is above all make sure that component A at least on those parts of the tissue is applied, where wrinkles are to be pressed during the subsequent pressing process, Preferably, however, the application of component A takes place on the entire Tissue surface.
- the application of component A, by the fabric or garment is impregnated by means of a bath or a liquor, e.g. by Immersion.
- it can also be an application by spraying component A on the tissue is done.
- component A must be in sprayable form, e.g. in mixture with a diluent.
- component B is recommended especially if component A is a low molecular weight compound, e.g. a monomeric diisocyanate or a Oligomeres having a molecular weight of less than about 1000.
- a component B is used, for example, with regard to felt-free equipment.
- the fabric or garment receives a good felt-free equipment.
- component A is a polymer having a molecular weight of is more than 1000, the benefits of using component B are beneficial; Eg receives the Tissue after performing the method according to the invention a pleasantly soft Handle when a softening agent is used as component B.
- softening agent on or in addition to component B on the fabric which does not fall under the definition of component B mentioned below and in claim 2 fall.
- softening agents known from textile finishing, such as e.g. Fatty acid, fatty alcohol or fatty amine derivatives.
- a component B is used is, the components A and B and optionally other components simultaneously on the fabric or garment applies.
- the application of the Component A also before or after application of component B. This is less but may prove to be necessary or appropriate in an individual case, e.g. if no stable formulation can be found which contains the components A and B.

- the procedure is such that the fabric with an aqueous liquor treated, which contains A and B.
- squeezing and spin are preferably carried out so that the tissue then a Liquor pickup of 10 to 80 wt.%, Preferably 30 to 60 wt.%, Based on the dry tissue before impregnation with the liquor. After squeezing or Thus, the tissue should gain weight in the stated range, based on dried fabric before impregnation, exhibit.
- the concentrations in the Treatment liquor are preferably chosen so that on the tissue after the Squeezing or spinning 0.25% by weight to 2.5% by weight of component A and 0.05% by weight to 0.5 wt.% of component B, preferably 0.5 to 1.8 wt.% A and 0.1 to 0.3 % By weight. These values are each on dry fabric before the impregnation process based.
- a weight ratio of component A to Component B is present in the range of 10: 1 to 3: 1.
- the moisture content of the fabric or Garment After applying the components A and optionally B to the tissue and if necessary, take off or squeeze to the desired liquor pickup, before the desired wrinkles are pressed, the moisture content of the fabric or Garment to 10 to 80 wt.%, Preferably 30 to 60 wt.% Are set.
- One Moisture content in this area at the beginning of the pressing process is a crucial one Requirement of the method according to the invention.
- those places where then the wrinkles are to be pressed in have a moisture content in the own area. If, as described below, after the Abschleudem or Squeezing before pressing the folds still further operations such. toppers carried out, the adjustment of the moisture content is carried out after these operations.
- the values given for the moisture content mean the amount of water which is present on the fabric, based on the weight of this fabric after drying at 110 ° C for 30 minutes.
- the serving as a reference commodity weight is thus among these Conditions dried tissues on which already component A and optionally Component B (with the exception of the ingredients used in the drying conditions are volatile).
- the mentioned range for the moisture content is therefore to be observed before with the pressing process is started. Before its implementation must therefore the moisture content be determined if he is not already on the basis of empirical values and process parameters is known. Depending on the conditions of the previous treatment, the Moisture content already in the required range.
- the moisture content of the fabric or garment is already in the required area is located.
- the tissue is clamped at two ends, e.g. a pair of pants at the top and bottom The End. Subsequently, the tissue is briefly heated with a stream of heated air or with a Treated mixture of water vapor and air.
- a stream of heated air or with a Treated mixture of water vapor and air For example, in the case of trousers it is convenient to clamp the pants at its upper and lower end, at the bottom to close and blow air from above into the inside of the pant legs.
- the air which in the Normally has a temperature of about 40 to 120 ° C and is dry, permeates the Tissue.
- This process of Topperns can after the application of the components A and optionally B and then squeezing and centrifuging the fabric done. It is advantageous to perform the Topperprozeß so that the fabric or garment does not dry, but still a humidity of 10 to 80 wt.%, Preferably 30 to 60% by weight. This is the range of moisture content that the fabric will have must have subsequent pressing at least at those points where folds should be pressed.
- the moisture content of the tissue after topping can be over the temperature of the heated air or over the duration of the supply of this air to be controlled. Instead of blowing heated air alone, you can do that that at the beginning a mixture of superheated steam (120 ° C) and air is used and then only air.
- an ironing operation can be performed on areas where later no wrinkles are to be pressed, for example, to make seams on the inside of the To iron trouser legs by hand.
- this should be done under mild conditions.
- the subsequent pressing process in which wrinkles 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 wt.% Has. These values give the water content of the fabric on, based on dried tissue, as described above.
- the tissue must be at least in the places where wrinkles are to be pressed, a moisture content in this Have area. Normally, the tissue has a moisture content throughout this area.
- wrinkles are pressed in the next step, e.g. Creases on trousers or pleats on skirts.
- the wrinkles can be in an earlier Process step have already been preformed by applying a light pressure. It But it is also possible to produce wrinkles in a hitherto wrinkle-free tissue.
- the fabric is designed accordingly, so that at the desired location a Fold is preformed. This is now at a temperature in the range of 80 to 200 ° C, preferably pressed 130 to 170 ° C using a pressure.
- the specified Range for the temperature is not the temperature of the pressing tool is (the higher can lie), but the temperature, which exhibits the fabric in the places, where the Wrinkles are pressed, on the surface facing away from the pressing tool.
- the temperature of the tissue on the Preßwerkmaschine remote surface can be measured by means of a temperature sensor and be controlled via the process parameters.
- the tissue in the places where wrinkles pressed have a certain moisture content.
- the tissue in the places where wrinkles pressed have a certain moisture content.
- the pressing process is preferably carried out in these cases so that the tissue or Garment in places where wrinkles were pressed, after pressing practically is completely dry. Otherwise, the permanence of the fold can be compared to washing processes be worse. A complete drying of the fabric can be easily on the Achieve the duration of the pressing process.
- the pressure to be applied when pressing the wrinkles can be varied widely. He will suitably adapted to the tissue properties and is preferably in the range from 1 to 10 bar. For the pressing process commercial equipment is suitable, which allow to achieve the required pressures and temperatures.
- the duration of the pressing must be at least so high that the fabric or garment in the places where wrinkles are pressed, after pressing the desired Has moisture content. This can vary depending on the fabric type. A longer one Dwell time of the tissue in the press is not required in most cases, but can in the Be an individual case of advantage. Normally, the duration of the pressing process is about 5 seconds up to several minutes, depends i.a. from the pressing tool.
- the fabrics may be dried in air at room temperature or elevated temperature (eg in a drying oven) until they reach equilibrium moisture content. Subsequently, further, customary in the manufacture of ready-made fabric process steps can be carried out, including ironing by hand at the places where no wrinkles were pressed.
- 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 stopped for 20 seconds by placing them on their top and bottom clamped lower end of the pants legs closed and from the top in the inside of the pants first a mixture of saturated water vapor for 10 seconds (120 ° C) and hot air and then for 10 seconds only hot air injected.
