Definitions

  • the invention relates to a method for treating textiles and a washing machine, which is designed to perform the method.
  • Textiles are roughened by wearing and subsequent washing because textile fibers break up as a result of this cycle.
  • the surface of the textiles thereby loses color gloss.
  • pilling occurs. That is, individual textile fibers break off during wear and washing and accumulate to form small nodules remaining on the fabric. In the area of broken fiber ends, dirt particles can settle, which can no longer be removed in the usual way during washing. This makes the textiles gray.
  • a method for providing a color clearing of laundry comprises treating the wash with a soaking, washing or rinsing liquid comprising an enzyme exhibiting endoglucanase activity.
  • the enzyme is encoded by a specific DNA construct or at least 90% homologous to a particular amino acid sequence.
  • the invention thus has the problem of providing a method for treating textiles and a washing machine, with which a rejuvenation of the used textiles can be achieved.
  • the advantages achievable with the invention are a graying and pilling of textiles in a single wash, i. to effectively remove with a single use.
  • the textiles are visually upgraded by the treatment. They can be carried on and do not need to be disposed of. In addition, damage to the textile structure is kept relatively low.
  • the invention relates to a method for treating textiles in a washing machine with a tub for receiving washing liquid and a rotatably mounted in the tub drum for receiving the textiles, in which a washing program is started with a total running time of at least 110 min.,
  • the Lye container is supplied to a rejuvenating agent-containing washing liquid and the textiles located in the drum is washed in the rejuvenating agent-containing washing liquid.
  • washing liquid in the context of the invention comprises water which may further contain detergent.
  • water is a sub-term of the term “scrubbing liquid” and is used in some places in the description when it refers to scrubbing liquid which is definitely not intended to contain detergent, for example, in a rinse phase of the scrubbing program, water is added to the scrubber which is usually non-detergent Contains detergent.
  • the rejuvenating agent-containing washing liquid supplied to the tub in the rejuvenating agent-containing washing liquid prior to the step of washing the fabrics located in the drum preferably contains, besides the rejuvenating agent, a detergent more preferably a fine or wool detergent.
  • a detergent has various detergent components depending on the desired type of fabric to be treated.
  • a full or color detergent contains surfactant (s), builder (s), enzyme (s) and optionally other ingredients.
  • Other ingredients may or may be builders, co-builders, foam inhibitor (s), chelating agents, sequestering agents, enzyme stabilizer (s), dye transfer inhibitor (s), optical brighteners, UV absorbers, thickeners, water softeners and / or fragrance (s).
  • a fine or wool detergent may also contain the ingredients mentioned above, but may also be enzyme-free.
  • the rejuvenating agent is a colorant.
  • the colorant is suitable for refreshing a color of the textile and possibly changing it.
  • a detergent containing the colorant as a rejuvenating agent may further contain a color fixer.
  • the dye fixing agent can also be supplied spatially and / or temporally offset to the dyeing agent to the tub.
  • the colorant may be a colorant for color renewal of the laundry, such as faded jeans.
  • the colorant may be a pure textile dye suitable for dyeing textiles such as for coloring white table linen.
  • the colorant may further be a special colorant, which is suitable, for example, for dyeing graying lingerie.
  • the rejuvenating agent is a natural fiber-reactive enzyme.
  • the textiles to be treated by the process then preferably comprise natural fibers.
  • the textiles may be a mixed wash or a pure natural fiber wash.
  • the rejuvenating agent is a cotton reactive enzyme.
  • the method is then particularly suitable for the treatment of cotton textiles.
  • the cotton textiles may be textiles containing, in addition to cotton fibers, other natural or synthetic fibers other than cotton, or textiles made of cotton.
  • the rejuvenating agent is cellulase.
  • the textile to be treated is preferably a cotton-containing textile or a pure cotton textile.
  • the scrubbing liquid containing the rejuvenating agent contains no further enzyme in addition to the cellulase.
  • the rejuvenating agent is a component of a detergent
  • the cellulase-containing detergent with the exception of the cellulase, is enzyme-free, i. In addition to cellulase, it does not contain any other enzyme.
  • the detergent is therefore preferably an enzyme-free fine or wool detergent which additionally contains cellulase.
  • the washing program has a total running time of at least 120 minutes, preferably at least 130 minutes, more preferably at least 140 minutes, even more preferably between 120 and 140 minutes. This ensures that the rejuvenating agent has a sufficient exposure time and thereby the result of the treatment to rejuvenate the textile is optimized.
  • a detection phase, a washing phase, a rinsing phase and a spin phase are preferably carried out. More preferably, the washing program consists of performing the detection phase, washing phase, rinsing phase and spin phase in the order given. That is, during the entire duration of the washing program, the detection phase, then the washing phase, then the rinsing phase and then the spin phase are performed.
  • the detection phase laundry located in the drum of the washing machine is detected and water supplied to the tub of the washing machine, so that thus further containing a rejuvenating detergent supplied to the tub and the Rejuvenant-containing scrubbing liquid is formed by mixing the water with the detergent containing the rejuvenating agent.
  • the washing phase usually follows one or more heating sections (reheat should be possible), in which the washing liquid is heated by turning on a radiator of the washing machine to the temperature that is set by the washing program. After reaching the predetermined temperature of the radiator is switched off and a Nachwaschabites follows.
  • the laundry is moved by means of a rotating drum, whereby the washing liquid cools.
  • the washing phase is ended with a pumping out of the washing liquid from the tub, which may possibly also be spun so that the laundry detergent added washing liquid is effectively removed from the fabric of the laundry.
  • the rinsing phase which has a rinsing section or several rinsing sections, in which or each of which water is introduced into the tub, the laundry is moved therein and the water is pumped off at the end of the respective flushing section.
  • the spin phase then follows to dewater the laundry.
  • the drum is rotated at a higher speed compared to the washing process, in which the laundry rests against the drum shell and the water and possibly washing liquid is thrown outwardly from the fabric of the laundry due to the centrifugal force acting through openings in the drum into the tub , The water and possibly the washing liquid are removed from the tub.
  • the rejuvenating agent-containing scrubbing liquid is formed from water and a detergent containing the rejuvenating agent.
  • the rejuvenating agent-containing detergent is portioned in a capsule cup designed as a disposable container, which is or is arranged in a Ein Albanykasten the washing machine. It can thereby be ensured that the rejuvenating agent is used in a concentration which ensures a good regeneration effect for the laundry, without damaging the laundry or at the same time minimizing damage to the laundry. It is thus obtained an optimal treatment result.
  • the capsule cup is / are preferably arranged by the user in the dispenser box. Alternatively, it can also be automatically fed into the dispenser box of the washing machine. When carrying out the method, the capsule cup is arranged in the washing machine.
  • the rejuvenating agent-containing detergent By porting the rejuvenating agent-containing detergent on the one hand prevents the user of the detergent with this comes into direct contact. If the rejuvenating agent is a colorant, the likelihood of it becoming soiled is minimized. If the rejuvenating agent is an enzyme such as cellulase, which can cause allergic reactions, also possible direct skin contact is minimized or completely prevented.
  • Capsule cups and washing machines suitable for inclusion and use during a wash program are for example from the EP 2 463 435 A2 and the EP 2 597 191 A2 known. For example, in the capsule cup 20 to 60 g, preferably 30 to 50 g, more preferably 35 to 45 g of the rejuvenant-containing detergent. This port is preferred for a washing machine as a household appliance. A washing machine, which is designed for commercial use for a larger load of laundry, requires a capsule container correspondingly more content.
  • the detergent preferably contains 2.5 to 10.0% by weight of rejuvenating agent, based on the total amount of the detergent, ie of 100% by weight of detergent. More preferably, the detergent contains from 4.0% to 7.5% by weight of rejuvenating agent, based on the total amount of the detergent, of 100% by weight.
  • the detergent may be in powdered form but is preferably liquid. It preferably comprises conventional components of a mild detergent and, as further mildewash-unusual component, cellulase.
  • a wash temperature of the wash program is equal to or less than 40 ° C. More preferably, the washing temperature is in the range between 30 and 40 ° C. Washing at these relatively low wash temperatures has the advantage that the textile fibers are not damaged as much as at higher wash temperatures. The indicated wash temperatures are sufficient, however, to achieve the rejuvenation effect.
  • the invention further relates to a washing machine with a tub for holding washing liquid and a rotatably mounted in the tub drum for receiving the textiles and a control or regulating device which is adapted to regulate the method according to one or more of the described embodiments and / or control.
  • the washing machine preferably has a Ein Hugheskasten, so that the detergent can be arranged in it in the washing machine, for example by the user.
  • the washing machine is more preferably designed to flush the rejuvenating agent-containing detergent from the capsule cup located in the dispenser box into the tub.
  • the arrangement of the rejuvenant-containing detergent in the capsule cup has the advantage that the user does not have to measure the amount of detergent to be used and does not come in contact with a detergent in powder or liquid form when filling in the dispenser, but the detergent in packaged form in the Ein Cypruskasten the washing machine can fill. This is advantageous both in the colorant and in particular in an enzyme as the rejuvenating agent, because enzymes can trigger allergic reactions on skin contact.
  • the user is with providing the method with a rejuvenation of textiles at the touch of a button where it does not have to perform manual steps other than loading laundry into the drum and placing the capsule cup in the dispenser box. Furthermore, the detergent is consumed in the capsule cup, so that no residual amount of the detergent remains, which remains in the dispenser and then can act on subsequent washes. The user can practically dispose of the capsule cup consumed during the process after the end of the process.
  • the washing machine is preferably designed such that it can at least partially open the capsule cup.
  • it may have thorns on the dispenser, which introduce holes in the capsule bowl such as when inserting the Ein Cypruskastens into a slot of the washing machine or when placing the capsule cup in the Ein Honeykasten such that the detergent can be flushed out of the capsule cup.
  • the detergent in the capsule cup is preferably in liquid form.
  • the washing machine can be a washing machine or a combination appliance such as a washer-dryer.
  • the washing machine can be designed as a privately used household appliance or as a commercially used device.
  • Fig. 1 shows a partial supervision of a washing machine 1 with a housing 2 and a Ein Hugheskasten 4, which is partially pulled out of the housing 2.

  • the laundry is moved by means of a rotating drum, wherein the washing liquid cools.
  • the washing phase 12 is ended with a pumping out of the washing liquid from the tub, wherein optionally also can be thrown, so that the washing liquid located in the textile fabric of the laundry is effectively reduced.
  • the rinsing phase 13 which has one or more rinsing sections, at which or which fresh water is introduced into the tub, the laundry is moved therein and the sunken water is pumped off at the end of the respective flushing section.
  • the spin phase 14 then follows to dewater the laundry.
  • the drum of the washing machine 1 is rotated with respect to the washing increased speed at which the laundry is applied to the drum shell and water and possibly washing liquid due to the centrifugal force from the fabric of the laundry to the outside through openings in the drum in the tub is thrown, the water and possibly the washing liquid is removed from the tub.
  • the washing program 10 starting from the acquisition phase 11 and ending with the spin phase 14 takes 120 minutes in this embodiment.
  • the total run time of the wash program was 120 min.
  • the fabrics were washed twice with the above wash program, with the fabrics additionally rinsed with water after each wash program at 90 ° C without detergent. After the first wash, pilling and graying could be effectively reduced, and a further slightly improved appearance of the textiles became visible after the second wash.
  • the breaking force loss according to ISO 13934-1: 2013 was about 8% after the first wash and about 16% after the two washes. The method is therefore effective on a single application to free textiles from pilling and graying and rejuvenate without unduly damaging the textiles.
