Description

Dyed and Dustcloth

description

The invention relates to color and dirt traps, which are in the form of folded textile or paper-like fabrics and as nonwovens and for cleaning, washing and grooming in particular in

Washing process of laundry are used.

When cleaning objects especially in washing machines such as washing of textiles, for example clothes, smocks, bedding, fabrics, the problem is that although by the use of detergents in the wash liquor the dirt and other contaminants such as bacteria, fungi and

Larger particles are largely detached, but often the following disadvantages.

Dyes dissolve away from dyed articles, which then virtually dissolve as

Reduce impurities on other items so that discolouration can occur on white items and on lighter-colored ones

Articles for moving the color.

In addition, there is a risk that dirt, which still herumvagabundiert in the wash liquor, settles again. This also applies to other particles such as e.g. Pigments.

Not to be overlooked is the fact that the washing liquor flowing out after washing is loaded with impurities and

Can create environmental problems, often costly

Preparation measures are required, especially if questions of

Hygiene and health are in the room.

There has been no lack of attempts to remedy this situation, and there is extensive patent and technical literature in this field.

CONFIRMATION COPY Thus, in DE 3 834 699 AI fiber webs are described, the

can be used as a dirt trap in wash liquors. The nonwovens can be composed of synthetic fibers, but also of cationized cellulose fibers. To load them with liquid detergents, a liquid-impermeable film is applied on one side of the nonwoven and then introduced from the other side, the liquid detergent. This is to prevent liquid from leaking on the opposite side.

In US 4 170 565 substrates for cleaning laundry articles are described, which consist of two superimposed layers of a

water insoluble substrate, wherein one or both substrates have an air permeability of at least 30 cubic feet per square foot and have 5 to 95 weight percent of a water soluble surfactant between the two layers.

Another development is described in DE 10 2009 027 046 AI. There, a coated textile washing article is disclosed, which

water-insoluble textile substrate and a detergent composition solidified on the substrate, the substrate being equipped with a permanent equipment having mud-trap properties.

EP 0 264 831 A1 describes a melt-spun fabric which is impregnated with up to 300 g per square meter of liquid detergents; after squeezing, it is still dried.

An improved form of presentation is described in WO / 2012/113360. It is about a compact, deployable molded body, which is prepared by a multi-layered wet-strength textile or paper-like fabric processed in particular rotationally symmetrical to a shaped body, provides with a binder, if necessary, incorporates active ingredients and dried.

Although many dyeing and Schmutzfangtuch for washing purposes in a variety of packaging and methods for their preparation are known, there is still a need for improved

Manufacturing process for such products and after such products with improved properties and more extensive

Applications.

The object of the invention is therefore to provide advantageous and versatile dyeing and Schmutzfangtuchchen for washing purposes and an advantageous method for their production, which works environmentally friendly and energy-saving and easy to perform and leads to products with advantageous properties with which it is possible is easy and targeted and quantitatively to enter detergents and active ingredients in the wash liquor, which are fast and deliberately bring their dirt and Farbfangigenschaften and their washing and care properties to advantage and can be advantageously prepared for example in certain standard versions on stock and can be packaged and stored well in larger quantities, and then simply and effectively if necessary even with special and also, for example, difficult active ingredients can be provided and where it is possible to use active ingredients that could otherwise be used with the known methods or only with great difficulty.

The object of the invention is also to provide not only for the cleaning of dirty laundry but optionally to ensure that certain pollutants such as nanoparticles are not derived with the wash liquor after the washing process and can thus enter the groundwater.

This object is achieved by ready-made dyeing and Schmutzfangtücher that are folded one or more times, are composed of an activated paper-like or textile-like fleece and with solutions, emulsions or liquid

Dispersions containing detergents and / or detergents and / or detergents are provided inside the folded area, wherein the amount of solvent, emulsifier or dispersant in the finished article is 20 to 400 wt .-%, and made by cutting or punching are.

The nonwoven comprises synthetic and / or cellulosic fibers.

The nonwoven advantageously contains fibers which absorb nanoparticles.

The nonwoven is preferably cationically or anionically activated.

The prefabricated, folded dye and dirt scarfs may be advantageously packaged in sealable bags, tubes, sachets or other containers.

Another object of the invention is a process for the preparation of dirt and Farbfangtuchern, which are particularly suitable for use in the washing of textiles, which is characterized in that textile or paper-like fabrics, in particular nonwovens folds and inside the folded area with solutions , Emulsions or liquid dispersions containing active ingredients such as detergents and / or washing aids and / or laundry care compositions, provides and made up, wherein the amount of the solvent, emulsion or liquid dispersing agent is such that the concentration of the liquid in the assembled article 20 bis 400% by weight. An advantageous embodiment of the method according to the invention consists in subjecting one or more activated nonwovens, which are still moist, to a Z-folding, wherein the oversizing with the solutions, emulsions or dispersions is carried out via the folding stirrups, which have openings for them , eg in the form of round holes or slits. It is advantageous to additionally introduce a solution, emulsion or dispersions via a spray nozzle. This can happen when the fleeces are still partially open, ie the folds are not quite finished. The folded and loaded webs are then stacked and assembled in several layers.

The invention may e.g. be carried out as follows, with individual

Features or indications also for characterizing the invention

be used, in particular for advantageous embodiments.

First, a nonwoven is made which has such high wet strength to withstand the mechanical stresses and temperatures experienced by the laundry during washing in the washing machine during washing. The finished, folded and loaded fleece unfolds in the washing machine and behaves in the washing liquid as the laundry, retains in particular its mechanical cohesion and fuselages not.

The fleece is built on the basis of fibers such as staple fibers or filaments. Particularly suitable are synthetic and cellulosic fibers.

For the formation of the fabric, conventional methods such as wet-laying, the draining process, but also the sponbonded process. These production methods are known to the person skilled in the art.

The activation is expediently carried out on the finished nonwoven, while the fibers get a function, the fibers are preferred here

cationized. Cationizing, Anionizing or Providing with Others

Functions are processes that are also known to the person skilled in the art. The fleece does not need to be dried after activation. The moisture remaining in the fleece has an advantageous effect when distributing the active ingredients. The activation can also be made before the web formation on the fibers. The folding of the nonwovens can take place using a plurality of parallel nonwoven webs. One possible method is the so-called Z-folding, in which the nonwovens are pulled over folding stirrups and in this way are continuously folded over. In the context of the invention, the bracket are provided with openings through which the interior of the folding surface

Active ingredients are introduced. Thus, the outer surfaces of the folded part remain largely free of active ingredients, which is very beneficial to the

Handling affects.

Then, the assembly takes place, in which the folded and loaded with active substances webs are cut or punched to the desired size. You are then ready to use. They can also be packaged very well, especially in larger stacks, for example 50 or 100 pieces. As a packaging material preferably waterproof plastic tubing can be used. These can come with an aroma-tight,

reclosable Laschenöffhung be provided so that a

Drying of the packaging content can be effectively prevented during storage, which has very positive effects on the active ingredients contained on the cloth.

The invention will be explained in more detail with reference to the following example. Again, individual features can be used to characterize the invention and individual advantageous embodiments thereof.

First, subjecting the wet-strength nonwoven material, e.g. from 50%

Viscose fibers and 50% polyester fibers in the hydroentanglement process and has a grammage of 50 g / m ² , a layer thickness of 0.6 mm at 0.05 N / m ² load, a tensile strength at Fmax MD = 95N / 5cm and CD = 21N / 5cm, an elongation at Fmax MD = 25% and CD = 150% and a capacity for liquid uptake of 1000% grouted.

Such a wet-strength nonwoven is chemically cationized in a conventional manner, to which the nonwoven fabric described above is drawn in a bath through an alkaline aqueous solution of 3-CUoro-2-hydroxypropyltrimethylammoniumchlorid and allowed to react so treated nonwoven fabric for several hours at 30 ° C.

Subsequently, the so treated fleece is repeatedly with water

washed out, with the washing water has added a little dilute acetic acid. The well-washed, cationized fleece is now allowed to drain well and then removes residual, adhering water by running it over a padder. A treated nonwoven still has a residual moisture of about 65% water. This wet nonwoven material is now unwound from the roll on which it is located and introduced into an apparatus in which it uses

Conversion straps bent from the edge, immediately loaded with the liquid or at least flowable active substances on the inside and is then completely folded, so that the active ingredients are covered when folding the fleece.

This procedure can now be carried out parallel to each other with several nonwoven rolls and store the resulting folded and loaded nonwoven webs one above the other. Particularly advantageous here is a continuous driving. Prepared nonwoven cloth sheets stacked in this way are cut to a suitable size in a special device or punched out in a suitable shape and finally packaged, e.g. in

Plastic tube films, which in turn are provided with resealable openings.

The invention represents a valuable enrichment of the state of the art. Thus, the manufacturing process works very energy efficient. Thus, the activated, e.g. cationized fleece without drying to the other stages of the manufacturing process are fed, at best, a more or less easy squeezing off by means of a padder is advisable to rid the fleece of loosely adhering water.

Since the inner surfaces of the folded towel are contacted by mistake with the active ingredients, the solutions, emulsions or liquid dispersions are distributed from the inside towards the outer surfaces of the folded towel

Subject, these surfaces remain largely free of active ingredients and thus can be well stacked and packed in larger quantities in suitable containers, e.g. in aroma and waterproof tubular films, sachets, boxes, etc.

The invention makes it possible to use the usual detergents,

Add washing aids and detergent and thus use the cloths for virtually all washing tasks. The cloths unfold in the washing machine without problems and move there we normal laundry. It is particularly advantageous, however, that even difficult active substances which can not be incorporated by conventional methods into dyeing and dirt-trapping cloths of the usual presentation can be well distributed in the wipes. This also applies to aggressive drugs that are in the tissues according to the

Invention are virtually shielded and are released in the washing machine. It is particularly advantageous that the wipes can be additionally provided with certain active ingredients prior to their use. They then function as so-called matrix substrates by additionally adding one or more active substances to the already loaded wipes. This is easily possible by opening the fold and additionally introducing an active substance, for example as a powder or as a liquid pours or sprayed. So you can not bring in long-lasting active ingredients, including enzymes, disinfectants and the like.

You can also, if special washing tasks arise through

Introduction of special components to adapt to specific problems.

In the washing process in the washing machine, the towels open without

Difficulties and behave like normal laundry, so no disturbing effects occur.

Of great benefit in these articles is the possibility of fixed

To be able to distribute active ingredient particles extremely finely on the inside of the folded nonwoven fabric as a fine dispersion. This is especially beneficial for fixed

Active ingredients that can lead to spot effects, such as "spot bleaching" or "spotcolouring" in the washing process. The slow and continuous release of the active ingredients (retarded release!), Which is the special way of packaging in the

folded, wet nonwoven cloth allows, now ensures that such

Spot effects can be avoided!

A very nice example of this is the loading of the fleece with dispersions of ultramarine blue, a powder that is very interesting as a natural whitener, but by its tendency to produce bruises on the laundry caused by local over-concentration of the mineral and settling of the same on the laundry, is considered problematic. In the

Application of the clothing according to the invention or placement of the active ingredients in the inner pocket of folded moist nonwoven cloths, such useful active ingredients can now be safely used.

Another advantage of this invention is the fact that one also in

Water sparingly soluble active ingredients such as the broad band biocide 4,4'-dichloro 2-hydroxydiphenyl ether pre-dissolved, for example, in propylene glycol in the inner pockets of the folded web applied. Because the cloth remains moist due to its waterproof seal packaging, the highly active form of this antimicrobial agent is obtained. Finally, as a great advantage of this invention must be mentioned the possibility that one can also apply so-called miniemulsions and keep stable during storage, which can go on for years. Such miniemulsions are therefore important for the treatment of textiles, especially in the washing process, as they affect the mode of action of microemulsions that migrate into the interior of textiles and of

Macroemulsions that have surface effects on textiles, connect in an elegant way, so verify both effects. However, such miniemulsions are not known to be particularly shelf stable because they tend to break the emulsions over time. But you wear these

Miniemulsions on a wet sheet such as the web described by us, so you can stabilize the metastable dispersion, since the fleece acts as a matrix that prevents dispersed droplets on the union and on access of excess water in the washing machine after opening the folded Tuches releases and then allows full development of its effectiveness.

An example of such useful mini-emulsions for the washing process are e.g. Silikonweichgxifrmittel.
