Description

107937 THE METHOD. TO REMOVE DOTS FROM TEXTILES

The invention relates to a method as defined in the preamble of claims 1 to 1. Further, the invention relates to a textile fabric softener and benzyl benzoate as defined in the preamble of claims 4 and 9.

The most important mites in dwellings are house dust mites, Dermatophagoides sp. Warehouse mites are a more heterogeneous group of mites than house dust mites, whose primary 10 habitats are eg hay and grain stores, but are also found in dwellings. Dust mites mainly feed on animal and vegetable fibers, molds, dandruff and flour. Protein from dust mites spread with room dust. 15 Proteins are respiratory allergens. Exposure to dust mites increases the risk of allergy and asthma.

Dust mites are recommended for example. vacuuming. On the other hand, it is questionable whether the cleaning behavior per se can influence the number of dust mites 20 since the frequency of dust mites is not related to the amount of dust.

The problem with dust mites is textiles, which cannot be washed at 60 ° C. Particularly problematic are bedding, which is a typical site for ticks, as it has a large amount of dandruff and skin secretions that have been removed from humans, and the moisture from sweating creates otherwise favorable growth conditions for them. Washing of bedding such as blankets, pillows, pillow cases and the like at 60 ° C is often not possible.

10 Another problem is that textiles cannot be handled in households for long periods of time at high temperatures or frost. The above treatments also require careful vacuuming to remove dead dust mites and allergens. Vacuum treatment also requires treatment with acaric acid. In addition, the problem is that thorough cleaning does not remove all mites and allergens.

The object of the invention is to eliminate the above-mentioned drawbacks.

In particular, it is an object of the invention to provide an effective and easy method for controlling dust mites from textiles which is particularly well suited. for household use. It is a further object of the invention to provide a method which can be used I '! in combination with well-known dust mite control • i. * 'supplements. It is a further object of the invention to provide a method for controlling dust mites' · '' for a longer period of time.

It is a further object of the invention to provide a rinse aid for use in combating dust mites - *: · *.

As regards the features which characterize the invention, reference is made to the claims.

35 The invention is based on a research work carried out to study the destruction of dust mites by textiles; and found to be non-toxic to humans, 3 107937 highly adherent benzyl benzoate kills the dust bag kit.

In the method of the invention, the textiles are rinsed with water to which acaricidal agent 5 has been added. Flushing can be done manually or by washing machine.

The acaricide is added to the rinse water or mixed with the rinse aid.

In one embodiment of the invention, acaricide 10 is mixed with the rinse aid and the rinse aid is added with the final rinse water. With the last rinse water, the acaricide adheres well to the textile surface and will not be removed by further washing.

Any known hand and machine washable rinse aid may be used in connection with fabric rinsing and washing 15.

The acaricide may be blended with 0.5 to 5% by weight of the fabric softener. Preferably, the amount of acaricide in the fabric softener is 1 to 4% by weight, for example about 3% by weight.

2 0 The acaricidal agent used may be any substance which is dust-mite-free but non-toxic to humans and which adheres well to textiles and is substantially odorless. For use as an acaricidal substance, no - / '*. such substances include e.g. benzyl benzoate and / or derivatives thereof, pyrethrin, piperonyl butoxide '1'. and / or the like.

In a preferred embodiment of the process, benzyl benzoate and / or its derivative is used as an acaricide. Benzyl benzoate is a · · · · * · 30 water-insoluble aromatic fragrance.

Benzyl benzoate is used e.g. perfume solid *: **: as a nitricant and as a chewing gum flavor. It kills dust · ***. ticks in low concentrations and is harmless to humans.

The fabric softener according to the invention contains from 0.5 to 5% by weight, preferably from 1 to 4% by weight, for example about 3% by weight of the above acaricidal agent

In one embodiment of the invention, the rinse aids contain, in addition to the conventional rinse aid components and acaricidal agent, a stabilizer. The amount of stabilizer in the fabric softener is 1-8 wt%, usually 2-6 wt%, preferably 3-4 wt%.

As the stabilizer, any suitable organic solvent may be used together with the fabric softener and the acaricidal agent, preferably lower alcohols, e.g. isopropanol and ethanol.

Thanks to the invention, the control of dust mites from textiles is enhanced. The invention provides 100% killing of dust mites 15 and a long lasting effect of up to 2 months against dust mites

A further advantage of the invention is the ease of controlling dust mites. Dust mite control does not require various measures to kill dust mites and remove dead dust mites and allergens, but to kill and remove dust mites and allergens during normal washing of textiles, while effectively preventing the growth of dust mites due to the long duration of the treatment.

The invention will now be described in more detail in the accompanying examples.

EXAMPLE 1 The experiment investigated the killer effect of dust mites on benzyl benzoate added to the fabric softener.

The test used a conventional machine-washable *: · 1: fabric softener, which removes textiles from the textile and makes the textiles soft and pleasant to smell. To the fabric softener was added 1, 2, and 3 l 1 · · 35 wt.% Benzyl benzoate and 3.5 wt.% Propanol to homogenize and stabilize the nucleus. 107937 dye was added to a washing machine at 60 ° C in a paste wash with the last rinse water.

In the studies conducted, no living or dead dust mites or aller-5 genes were found in the textiles at the concentrations of benzyl benzoate used. Investigations were carried out at approximately weekly intervals over several months. In the experiment, it was found that the acaricidal activity of the benzyl benzoate added to the fabric softener lasted for 2 months. The concentration of benzyl benzoate-10, such as e.g., 3 wt%, is effective in high and / or low rinse water washing machines and / or programs.

The invention is not limited to the above embodiments only, but many modifications are possible within the scope of the inventive idea defined by the claims.
