Invention field

The present invention relates to a kind of fabric article treating system that comprises apparatus and method, so that improved clean fabric, appearance of fabrics and/or fabric care benefit effect to be provided.More particularly, the present invention relates to a kind of effective and direct delivery system, directly deposit on the textile article to be processed by this system's detergent active material and rinse-active material.The invention still further relates to the New-type detergent composition and the Fabrid care composition that are used for these type of apparatus and method.Compare with the immersion aqueous cleaning system of routine, this system not only economizes on water but also is energy-conservation, and enhanced clean fabric and fabric nursing are provided simultaneously.

Background of invention

Conventional washing device and method based on water typically adopt the immersion washing.In other words, the amount of washing medium makes textile article be immersed in " free " or the excessive washing medium considerably beyond the receptivity of fabric load in the chamber.Yet submergence may not be effective or economic method for sending detergent active material or rinse-active material fully.When in a large amount of aqueous cleaning media, diluting, have only the active substance of little per-cent to contact, and most of active substance is lost in washing and the rinse fluid with textile article.And some active substance is to the avidity height of the avidity of water comparison fabric face, thereby even when these active substances when contact fabric is surperficial once in a while, can not distribute and drop on the fabric face from the aqueous cleaning medium.

A long-term existence is arranged but unsatisfied demand in the fabric detergent field always, promptly the active substance of high water soluble can be delivered on the fabric face, and do not have active substance to flow into the remarkable waste in waterways.Some active substance with high water solubility is delivered to fabric face makes the laundry detergent formulator be in disadvantageous position, their institute that has to needs the example of chemistry.On the one hand, the polarity of height can make active substance work and sends desirable beneficial effect, for example cleans dirt or interacts with dirt; On the other hand, these identical features stop active substance effectively to distribute most active substance " inflow water drain " from solution.Up to the present, there is considerably less (if any) gratifying method to achieve this end.For example, improve the surface-active strategy of active substance and can weaken the required polarity/wetting ability of performance performance usually, and " sending the enhanced activity material " (for example, high molecular weight polymers) causes not too effective cleaning or cost an arm and a leg through regular meeting.

In an alternative method, active substance sends or directly is delivered to fabric face by the washing medium of low capacity.Yet this method existence is assigned to the challenge on the whole fabric face in the fabric load in the chamber equably or substantially equably with the low capacity active substance.For example, can only be delivered to some zone and can not be delivered to other regional tensio-active agent and will cause uneven cleaning, perhaps even cause unacceptable clean-up performance failure.Another embodiment is a spices: spices is a kind of costliness and very effective active substance; Therefore, the spices of low capacity is used for fabric article treating process by the typical case, and needs to distribute uniformly basically.In other words, following mode be when sending spices do not expect that the textile article that is about to a kind of processing soaks into spices, and the another kind of textile article of handling only obtains a spices in zone, a place.

Described based on preamble, expect to have and a kind of these active substances are delivered to method on the fabric face effectively economically.This delivering method will make that it is feasible handling textile article with present available or novel active substance, and these active substances have low distribution factor between water-bearing media and fabric face.This delivering method will make that also it is feasible handling textile article with expensive active substance.

Described based on preamble, also expect to have the method for a kind of active substance of realizing low capacity even or basic uniformly distributing on whole fabric face, thereby the textile article of handling does not show to have blotchy or uneven effect.

Conversion between the speed of rotation of any particular chamber and the G power can use following formula to calculate:

$v=\frac{2\mathrm{\πr}}{t}$

a _c＝v ²/r

F _g＝a _c/g

Wherein r is the rotating cylinder radius;

T is the time of once rotating, and unit is minute;

V is a speed of rotation;

a _cIt is centripetal acceleration;

G is 9.8m/s ^-2(gravitational acceleration); With

F _gBe G power.

For example, radius is that the rotating cylinder of 26.6cm (10.5 ") need be with 4.1rad/s (per minute 40 changes (rpm)) rotation to produce the power of 0.5G.Identical rotating cylinder will produce the power of 0.9G with 5.7rad/s (55rpm) rotation.These exemplary embodiments do not have specific meaning, just illustrate calculating, with any critical range irrelevant (these scopes will be given in this paper other places) of operation, and can not be interpreted as limiting the scope of the present invention.

Be configured as to provide the speed of rotation of chamber 1 with apparatus of the present invention more than a relative outer chamber 2.The variable rotational speed that can select treatment chamber 1 is to realize the concrete beneficial effect of wash/rinse cycle different steps.In one embodiment, treatment chamber 1 is to produce maximum about 1G or about 0.7G to about 1G or the extremely speed rotation of about 3G power of about 0.5G, with rolling textile article when using treatment liq, thereby realize that treatment liq is deposited on the fabric face more equably.Low speed rotation also can cause the stirring of textile article in chamber 1.Chamber 1 is rotatable producing about 50G to about 450G or the about 150G centrifugal force of about 400G extremely, thereby can or be pressed on the wall textile article " rotation ", with the treatment liq in effective removal textile article and/or the chamber.

In another embodiment, antetheca 67 has and contains inlet 58 tubulose extension 55, and this inlet is used for to fabric treating unit 70 fillings and takes out washes, and with outer chamber 2 in inlet 58 concentric alignment.Same intervals is three lifting blades 60 on the inner periphery of peripheral wall 65, and it has the cross section of fundamental triangle or other shape.In a specific embodiment, the radial extension line that each blade shroud produces around turning axle 100 places of chamber 1 is symmetric shape and passes through its height.This makes the opposite spin of chamber 1 have equal lifting effect to the goods that will wash.Be to be understood that and what approve is that the washing machine of most conventional does not promote blade, and tumbler dryer has the lifting blade, it is designed to low speed and/or unidirectional " rolling " running.In addition, chamber 1 can comprise that along its internal surface flow deflector or other structure comprise within it fabric to help again configuration.

In another embodiment of the invention, treatment chamber 1 comprises at least two rotatable portion (not shown), and transmission system rotation treatment chamber 1 in some way, makes to produce rotation relatively between adjacent rotating part.Can make the stirring velocity of textile article in the chamber 1 be higher than the typical case like this and be present in the single part in the conventional washing machine, the speed in the fluid chamber.The embodiment of this type of reverse rotation treatment chamber is described in PCT and announces WO99/58753.

(A) The washing liq step of applying

The washing liq that is used for present method can be " in statu quo " or is administered to the concentrated cleaning compositions on the textile article with its " pure form ".In this aspect of the invention, detergent composition before the contact fabric goods not by any other thinner for example polar solvent dilute.In other words, fabric article treatment composition is before any discrete thinner of contact or other solution, with pure form contact fabric goods.These are different with conventional washing system, wherein with fabric article treatment composition, for example washing composition be added to excessive thinner and/or other solution for example in the water to form mixture, this mixture is the contact fabric goods then, perhaps more typically are to soak textile article.Therefore " pure form " is meant the detergent composition that the user obtains from the composition vendor, and pure form can comprise the water with the textile article active substance combination.Water typically is present in the liquid or paste detergent composition of pure form.

In another aspect of the present invention, washing liq also is prepared as follows: paste or liquid concentration detergent composition are mixed with water or granular detergent composition is dissolved/be suspended in the water, be applied to the washing liq of textile article with formation.Mix or dissolve and outside device, to carry out, perhaps detergent composition can be placed in the washing liq reservoir and and fill, perhaps under the liquid concentration situation, can use flow-through cell to mix and preparing washing liquid by water supply line.Term used herein " washing liq " is meant and both comprises that detergent composition wherein is administered to embodiment on the textile article with its pure form, also comprise dilution or predissolve detergent composition (for example, liquid concentrate, paste, particle) are administered to the embodiment on the textile article in advance.

Washing liq is administered on the textile article to be processed with basic distribution uniformly on all parts that are implemented in this textile article.The inhomogeneous distribution of washing liq often produces the cleaning spot at the out-of-proportion amount contact fabric of washing liq goods place, and makes not contact part or the undersaturation part is not processed or yet cleaning of textile article.It is especially true to be near or below non-submergence content place in the washings scale of construction.

The adopting factor combination distributes uniformly to realize that better washing liq is basic on textile article in system of the present invention, and this factor includes, but are not limited in a continuous manner or intermittence/pulse mode is used the thin washing liq that drips form; When using washing liq, move or the textile article that rolls makes all parts of textile article be exposed, wherein move or roll mode can be successive or intermittently; Forward or backward; Unidirectional, two-way or multidirectional; In conjunction with and/or use other structural element, for example promote blade, the cantilever of spraying, be rotated counterclockwise chamber portion, make handle during the bunchy of textile article be prevented from or minimize.

The homogeneity that is applied washing liq is represented as the spraying evenness index, and it can be measured by the following method.Representational textile article load (for example being described in the mixed goods load among the ASTM test D2960-98A) is put in the device.Also be included in the load in be the tracer of eight white cotton fabrics, it comprises the square of 25cm * 25cm; Thereby with the washing safety label each tracer is carried out mark then tracer is subdivided into 25 foursquare grids of 5cm * 5cm.The washing liq that is mixed with 1% standard red solution is administered on the load by application device, measures and be about 50% of dry weight.Then sample is removed, air-dry, colour intensity to each 5cm * 5cm square area of tracer is visually classified, be divided into 0 to 10 grade, 0 grade of corresponding benchmark cotton fabric sample wherein, 10 grades of correspondences are immersed in the washing liq solution that is mixed with dyestuff exsiccant white cotton fabric baseline sample more subsequently in 10 seconds fully.Can calculate average rank and standard deviation by 200 grades available from tracer.The spraying evenness index is that grade drops on average rank 0.5 standard deviation with interior sample percentage ratio.The spraying evenness index that the inventive method can be sent is greater than about 90.

Therefore, this method is very effective, because the amount of used washing liq can be low to moderate about 0.25 times of the textile article dry weight.This method allows that also very effective washing composition/dirt interacts, because do not exist excessive water to weaken this interaction.In addition, this method is allowed some hydrophilic detergent active material of use, this active substance is invalid in the immersion aqueous cleaning system of routine, this is because this type of detergent active material has weak relatively fabric avidity, more tendency is retained in and contains in the water-bath, rather than is deposited on the fabric face and with fabric/dirt and interacts.Specifically, present method can adopt the fabric that is in the suds as described below-water dispenser ratio (Q _i) active substance less than about 0.3.

In the methods of the invention, the used washings scale of construction of washing step is very low.By the washing liq of low capacity is applied directly on the textile article in basic evenly mode, the gained textile article is coated the washing liq film.In this type of film, detergent active material closely contacts with fabric face, and can suspend and/or remove the fabric face dirt.And the dedicated dye molecule is limited by this film and is difficult for transferring to another fabric face.

In one embodiment, the washing liq volume of using during the film washing step is less than handling the about 75% of dry fabric weight, or less than about 50%, or less than about 25%.In another embodiment, the washing liq volume of using is for handling about 50% to about 200%, perhaps about 75% to about 150% of dry fabric weight.

Because the washings scale of construction of using reduces, and the washing liq uniformly distributing is become more important on the textile article surface, thereby will minimize from many spots consequence of low capacity film textile treatment.For realizing uniformly distributing, suitable application device must be able to produce the acceptable spray pattern that causes even spraying to cover, and for example, the spraying evenness index that has as mentioned above is greater than 90.

Washing liq can comprise that the mist of washing liq droplet or mist use, wherein at least 80% (D ₈₀) or at least 90% (D ₉₀) the droplet diameter that has of droplet less than about 500 microns or less than 350 microns, perhaps less than 200 microns.

Adopt fog nozzle in one embodiment of the invention, this fog nozzle can be sent the plane fan-spray with solid circular cone sprayed volume, and wherein droplet size drops in the above-mentioned scope.Alternatively, can adopt atomizer, this atomizer can produce and comprise thin mist or the mist that drips, and droplet size drops in the above-mentioned scope well.Suitable atomizer is described in above and installs in the part.

The washing liq application process adopts a certain amount of washing liq to reach following best washing liq and fabric ratio.Be not bound by theory, it is believed that best washing liq is used to realize following purpose with the fabric ratio: (1) guarantees that most of washing composition closely contact with fabric, and (2) reduce dye transfer, soil redeposition and foam, and (3) keep this method inherent efficient.On the one hand, if do not add enough fluids, then clothes can not contact fully with washing liq; On the other hand, if add too many fluid, then have free (mobile) washing liq, this spissated washing liq can be moved on another part and causes such as dye decolored problem from dress.Thought before that best washing liq and dry fabric weight ratio existed ³/ ₄: 1 and 1 ¹/ ₂: between 1.Have now found that the film washing methods can improve or improves by considering some factors, for example change of textile material, its type of weave and thickness, its dirt degree and other exceed the unforeseen factor of washing composition formulator span of control.Why be like this because different fabric type and weaves can significantly change its degree of absorption to water.For example, some flimsy material of being made by synthon can only basic absorption be less than 100% of its dry weight before extra water becomes " dissociating " wash fluid, and thick cotton fabric extra water become " dissociating " but before the wash fluid basic absorption surpass 100% (for example, surpassing 200% sometimes) of its dry weight.If whole load tilts towards a kind of or other fabric type, the then best washings scale of construction can significantly be different from by the simple amount of measuring of dry fabric weight.

Have now found that washing liq and fabric ratio improved or that improve, i.e. " washing liq and the fabric ratio favourable to receptivity " can be with the washing liq measuringization, and this consumption can realize that above-mentioned film distributes, and can avoid excessive washing liq again." washing liq and the fabric ratio favourable to receptivity " is as giving a definition:

Z∶Y

The total mass of Y=dry fabric load, unit is kg

Z＝∑A ₁B ₁+A ₂B ₂+A ₃B ₃+....A _nB _n

Wherein 1,2,3 ... the number of the different fabric type/weaves of n=; B _nBe the quality that comprises the fabric load part of given fabric/woven type, unit is a kilogram; A _nIt is the uptake factor of given fabric/woven type, and equal [M/100], wherein M be described fabric be immersed in the water and subsequently with 41.8rad/s (400rpm) in perforated basket after centrifugal 5 minutes, the water yield that the 100g sample of described given weaving textile/type is absorbed, unit is g.

Therefore, based on washing liq and the fabric ratio favourable to receptivity, the inventive method adopts about 0.25 to about 2, or about 0.5 to about 2, or about 0.75 the best washings scale of construction to about 1.5 scopes is to send improved clean fabric beneficial effect.

(B) Optional culturing step

After step of applying, optional culturing step makes textile article and washing liq keep in touch enough for some time, so that intravital detergent active material of washings and water and dirt, spot, fabric face interaction.Sustainable about at least 1 minute of incubation period, or at least about 3 minutes, or at least about 5 minutes.On the other hand, in order to make this process effective, incubation period is sustainable to be less than about 30 minutes, or is less than about 15 minutes, or is less than about 10 minutes.

Randomly, incubation period can relate to heat or non-heat (for example, air cycle and/or ventilation) evaporative removal moisture by not heating with further thickening and washing fluid film.

Randomly, after textile article is washed the liquid contact, energy (heat energy and/or mechanical energy) is applied to the interior textile article of treatment chamber.Heat energy can be used as warm air, steam, microwave and other radiating capacity and applies.Mechanical energy can by rotate, be rotated counterclockwise, scroll process chamber 1 applies, and can be by strengthening from treating chamber locular wall outstanding blade 46, lug or other structure.

Without being limited by theory, it is believed that heat energy can strengthen the soil release characteristics of washing liq in the following manner.Heat energy can improve the interactional kinetics of composition/fabric/dirt.Heat energy can promote washing liq to carry out the transition to " mesomorphic phase ", and this shows to have more effective soil release characteristics mutually." mesomorphic phase " used herein or " intermediate phase " are meant any organized micellar structure, include but not limited to bar-shaped, hexagon and layered arrangement.About 10 ℃ to about 70 ℃ operating temperature range, mesomorphic phase can about 10% or bigger surfactant concentration under realize.But the heat energy elevated temperature is enough to cause the washing liq on the fabric face partly to lose its moisture content, makes washing liq become more concentrated to promote interaction, the formation of intermediate phase and the final soil release characteristics of fabric face.But the agent of heat energy activated bleaching, inorganic peroxy salt activator or peroxy acid; The non-limiting example of these heat-activatable materials is disclosed in US 4,248, and 928, US 4,220,562 and US4,100,095.Heat energy also can promote enzymic activity.

Mechanical energy can help to distribute washing liq to make it more be uniformly distributed on the textile article.The period that mechanical energy also can make the identical fabric product surface be in contact with one another minimizes, thereby minimizes dye transfer.Mechanical energy also for example, the dirt by the loose weave surface helps to improve cleaning efficiency.

(C) Rinsing liquid step of applying

Rinsing liquid can comprise pure water and optional rinse-active material.Because the washing liq of low capacity is administered on the fabric face to carry out the film washing step, so detergent active material, dirt and dedicated dye material are concentrated on the fabric face.Therefore, the purpose of rinse step is thoroughly to remove detergent active material, dirt and dye substance.In addition, if the removal of active substance, dirt and dyestuff is concentrating effectively finishing in early days of these materials, soil redeposition and dye transfer can be minimized.Simultaneously, need the total amount of rinse water that restriction is used for rinse step reducing water consumption, and will handle the contraction that causes by water in the textile article and minimize.

Based on above discussion, effectively rinsing can followingly realize: with the enough free-water of the first a large amount of rinsing liquid wash systems with generation abundant suspension detergent active material, dirt and dyestuff on fabric face, thereby these materials can be removed substantially by first rinsing.Usually, need be more than a kind of rinsing liquid to remove all detergent active materials, dirt and dyestuff.Follow-up rinsing needn't be used the water with the first rinsing liquid as much.In a typical embodiment, the amount of the first rinsing liquid is about 5 times to about 20 times of textile article dry weight, and the amount of follow-up rinsing liquid is about 1 times to about 10 times of textile article dry weight, or the first rinsing liquid about 1/5 to approximately ¹/ ₂The water inventory that is used for rinse step is about 5 to rise to about 50 liters, and perhaps about 5 rise to about 20 liters.

In one embodiment, rinse step comprises two to five circulations completely, perhaps usually is two to three circulations.The first rinsing liquid is typically pure water, and last rinsing liquid can comprise water and optional rinse-active material.Each circulation continues about 1 to about 15 minutes, and perhaps about 3 to about 10 minutes, and each circulation needn't be identical time span.Between rinse cycle, rinsing liquid is removed.Can or rotate treatment chamber 1 to produce about 50G to about 450G by high speed rotating, perhaps about 150G realizes the removal or the drying of rinsing liquid to the centrifugal force of about 400G.The alternate manner of removing rinsing liquid includes, but are not limited to use the expansion leather bag to extrude rinsing liquid, and contact spongy material sucking-off rinsing liquid uses vacuum pump sucking-off rinsing liquid.

Can by be used to use the same or analogous application device of washing liq and use rinsing liquid with droplet form, and in conjunction with rolling with uniformly distributing rinsing liquid, thereby promote tight contact the between rinsing liquid and the textile article, make soil redeposition and/or dye transfer between fabric face minimize the duration of contact that perhaps reduces between fabric face.In one embodiment, because rinsing liquid, the especially amount of first rinsing used, rinsing liquid no longer is spraying or atomizing, but with about 1 to about 20 liters/minute or about 1 be drawn in the chamber 1 to about 10 liters/minute or about 2 to 5 liters/minute speed.In another embodiment, the first rinsing liquid is drawn into and last rinsing liquid is sprayed or atomized.

In one embodiment, rinsing liquid is administered to indirectly on the textile article in the treatment chamber.In other words, with rinsing liquid be delivered to outer chamber 2 to content just in time below treatment chamber 1 bottom, and by rotation or scroll process chamber 1, rinsing liquid contacts through the perforation on treatment chamber 1 wall and with textile article in it.The advantage of indirect method is that textile article is not immersed in the rinsing liquid and steady motion, and therefore, soil redeposition and/or dye transfer can minimize.

The rolling of textile article during the rinse step, rotation or other motion even can promote the distribution of rinsing liquid.Yet this type games needn't be high speed (for example, less than 1G).But why so be the energy minimization of textile article is wrinkling and/or bunchy.Even the removal of rinsing liquid also needn't be carried out under very high speed between the circulation, thereby textile article can not be fixed on the treating chamber locular wall.

(D) Optional step

Randomly, be similar to the arrangement liquid that follow-up rinsing liquid or water content are lower than follow-up rinsing liquid, be applied to textile article, thereby textile article is organized the liquid contact substantially equably in the mode identical with the rinsing liquid application.Preferably, arrangement liquid comprises the fabric nursing active substance of planning to stay on the textile article.Therefore, the part of arrangement liquid is removed and to be chosen wantonly, in some embodiments, after the arrangement liquid application followed by drying step.

Randomly, drying step in the end carries out in same device after the rinse cycle.Dual installation (that is, washing machine and dryer are in a device) is known in this area.Should provide attendant advantages by optional device, and promptly make the human consumer can and carry out whole (being dried to drying) washing process in single assembly in a continuous manner, therefore save time potentially.
