Definitions

• the invention relates to a method and a device for dehumidifying articles of clothing.
• the present invention has for its object to provide a method and a device for dehumidifying garments, with which moisture can be removed from the garments gently with little energy.
• absorbent material moisture can be removed from the garment with little energy.
• the garment can be protected by a suitable design of the absorbent body. This is particularly simple since absorbent materials for making the absorbent body are generally soft anyway, so that they protect the garment. In this way, no prints are made in the garment and there is little or no crumpling. Subsequent smoothing is considerably simplified. If the absorbent is made of a hard material, the surface brought into contact with the garment can be made smooth.
• the absorbent body can be made of a foam, for example, which has pores into which liquid is sucked out of the garment due to the capillary action. Furthermore, the absorbent body can be made of a fabric or a fleece or felt made of fibers and in particular of microfibers.
• An absorbent body made of a fabric can have additional fibers to increase the absorbency, which are applied, for example, by flocking or incorporated in the form of loops.
• a fabric provided with loops is, for example, a terry cloth or terry cloth, and terry velor can also be used in which the loops are cut open.
• the absorbent body advantageously has hydrophilic materials.
• fibers in particular these can be, for example, cotton or polyamide fibers.
• the moisture to be removed can in particular be wash liquor or rinsing liquid for rinsing out wash liquor, which are used when washing the items of clothing.
• the absorbent body is dehumidified or dried after contact with the item of clothing. Due to the previous transition of the moisture from the garment to the absorbent body and the dehumidification of the absorbent body instead of the garment, numerous and advantageous dehumidification methods can be used since the garment does not have to be taken into account.
• any known method that does not destroy the absorbent can be used to dehumidify the absorbent.
• mechanical pressing processes can be used, since the absorbent body is either already resistant to mechanical pressure anyway or can be designed in this way with little effort.
• the absorbent body can be designed as an inexpensive replacement part, so that wear of the absorbent body material can be accepted.
• Mechanical pressing processes have the advantage that they can be carried out with simple means. are bar and remove the moisture or liquid with a low energy consumption.
• the garment in a continuous process is contacted with an absorbent body in contact, which is then dehydrated again.
• a section of an absorbent body can be in contact with a piece of clothing and dehumidified.
• a circumferential, closed suction body can be used, the path of movement of which runs from a piece of clothing to a dehumidifying device and back.
• a band-shaped absorbent body can be used, which rotates over deflection rollers, the items of clothing to be dried being able to be moved between a deflection roller and a pressure device, in particular in the form of a pressure roller.
• the items of clothing are moved at the same speed as the surface of the absorbent body, it can be achieved in this way that the absorbent body rolls on the item of clothing, so that a relative movement between the absorbent body and the item of clothing and thus abrasion of the item of clothing is avoided.
• the garment can be brought into contact with an absorbent body from different sides. This allows a larger area of the garment touched by absorbent bodies and thus the dehumidifying effect can be improved.
• the garment can also be used with a gas jet in particular. an air jet. pressed-1. This prevents marks from solid objects on the garment.
• gas jets or compressed air jets can be applied to the garment in order to smooth it.
• a gas jet which is preferably an air jet and exerts a force on the item of clothing to be smoothed, a smoothing effect can be achieved with little effort, which is also very gentle on the item of clothing.
• the fabric of the garment can be pressed in at places or a tensile force can be exerted on the entire garment, whereby it is tensioned. Any wrinkles that may be present are smoothed in this way.
• This smoothing effect of the gas jet can be increased by relaxing the fabric of the garment before the smoothing process or at the beginning of the smoothing process, by moistening and heating the fabric of the garment.
• water vapor can be mixed into the gas jet and can thus be directed onto the fabric.
• a force is necessarily exerted on the garment by the at least one gas jet. This can adversely move the garment and possibly crease it. This can be prevented, for example, by using a gas jet which has a high outflow rate but a small diameter. This means that the gas jet as a whole does not exert a large force on the garment and therefore has little influence on its position, but can nevertheless achieve a high tension effect on the fabric in a small area on the garment and thus achieve a high level of smoothing. It can be provided that the deflection of clothing is suspended. due to the gas jet is at least partially compensated for by pulling the garment suspension slightly towards the nozzle from which the gas jet flows.
• the garment is advantageously supported during the exposure to the gas jet. This can prevent the garment from being moved by the force of the gas jet. Furthermore, a stronger gas jet can be used and a better smoothing effect can be achieved.
• the support can be done by means of fixed supports such as at least one support surface. If the garment is moved, for example, to go through several treatment stations, such supports can also be set up in such a way that they can move with the garment. For example, at least one support roller can be used which is rotatably mounted about an axis which is at least substantially oriented perpendicular to the direction of movement of the garment.
• the garment is supported by a gas jet.
• the garment is subjected to at least one gas jet from both sides.
• imprints in the tissue can be avoided, which can occur with solid supports.
• the smoothing effect is enhanced, since a force is exerted by a gas jet from both sides.
• the gas jets acting from both sides can in particular be matched to one another in such a way that the section of the garment located between them is deformed in a certain way in order to achieve a good smoothing result.
• the force exerted by the gas jets from both sides can each be distributed over a certain area with a non-uniform force distribution.
• the force distributions over the surfaces on both sides can be set differently, so that in one section of the garment the force exerted by the first side on the section is greater than the force exerted by the other second side and in an adjacent section that by the second Side force prevails.
• the garment can be deformed in a defined manner, so that it assumes, for example, a corrugated shape or elevations are formed in one or the other side in the garment.
• a gas jet can be used from one side, which widens like a cone and is hollow on the inside, so that it exerts a force in an annular shape on the surface of the garment. exerts region and a gas jet is used from the other side, which generates a force only in a small punctiform or circular region, the punctiform or circular region being within the annular region of the force exerted by the opposite side.
• This causes the fabric of the garment to be stretched and smoothed between the annular area and the point or circular area located therein.
• an essentially linear surface pressure can also be selected.
• the force in these areas can be tensioned and smoothed with a force acting in different directions in adjacent areas.
• the location of the item of clothing or a section of the item of clothing is recorded and the recorded location is used as the input variable of a control system which regulates the gas jets acting on the item of clothing from different sides in such a way that the item of clothing or section of the garment is always at a predetermined target location or target location area.
• the location detection can be carried out with light barriers or reflex light barriers, whereby other methods for distance measurement or location detection can also be used, for example by means of ultrasound.
• the fabric of the garment can be stretched gently but at the same time vigorously and thus achieve a high smoothing effect.
• the force distribution and / or the force exerted by the individual sides can be used Total force can be changed over time, so that an alternating deformation is achieved, which can have an advantageous effect on the smoothing process.
