DE20023525U1 - Underwear item or bed linen has metal coating on side facing user's skin - Google Patents

Abstract

The metal coating (7) has an antimicrobial effect when in contact with skin. The coating contains silver or copper and amounts to 20% of the total weight of the textile (4). The item is made of a knitted or woven fabric and the coating is applied permanently and wash resistantly in an immersion process.

Description

The Invention relates to a piece of laundry.

In the JP 10 310 975 A A laundry article is specified which avoids infections and the multiplication of bacteria, especially in a period of high humidity, such as in the rainy season, and avoids antimicrobial effects by using and mixing fibers provided with silver in a predetermined area, for example underwear. Here, silver is deposited on the surfaces of synthetic fibers by means of deposition and plating, fibers or threads of this type being used or mixed in a predetermined area. The silver content here is between 8 to 10% per unit area of the area concerned.

Out the US PS 968854 it is known to shield electromagnetic Radiations made of synthetic fibers with silver coat, the silver content of the coated with silver synthetic yarn preferably not less than 20% by weight should be and the conductivity of the silver-coated yarn should preferably not be less than 1.2 Ω / cm. However, such fabrics are used as outerwear, i.e. are not worn directly on the skin and are in the form of shirts, Pants, sheets etc. implemented.

The The invention has for its object to provide a piece of laundry which a Treatment of microbial-induced skin diseases supports or can even replace appropriate medication.

This The object is achieved by the solved in protection claim 1 features.

Further Developments of the invention result from the subclaims.

For skin diseases and skin irritations are often microbes such as bacteria, fungi or viruses responsible. To correct or alleviate corresponding Symptoms are usually medically effective ointments or gels medication to be administered otherwise.

The Laundry item according to the invention supports such Skin diseases or even replace appropriate medication. According to the invention at least the side that can be brought into contact with the skin of the user of the laundry with a metal coating that has an antimicrobial effect on skin contact Mistake. This can be a copper layer or preferably Trade silver plating. A piece of laundry equipped in this way shows when worn the skin and especially with close and prolonged contact antimicrobial effect, including a kill can be understood by germs, bacteria, viruses or fungi. By such support accelerated to a microbially contaminated skin sphere Healing process of diseased or irritated skin areas take place.

This is particularly related to the treatment of neurodermatitis significant.

On positive side effect of the metal coating is that electromagnetic radiation can be shielded. This also means a certain Reassurance for the skin sphere and is for conducive to restful sleep.

Further it should be noted that underwear items implementing the invention are undergarments, bed linen, socks, Gloves or wound care materials such as wound dressings or the like are to be understood.

The Finally, invention relates also the use of a textile with at least one metal-coated Site for the production of an antimicrobial effect on skin contact Laundry article.

Further Features, details and advantages of the invention are further claims as well as the following description in which an embodiment the subject of the invention is explained in more detail with reference to the accompanying drawings. Show it:

1 1 shows a schematic view of a piece of underwear in enlarged detail,

2 a perspective, cut-away partial view of a coated thread in accordance with a piece of laundry. 1 fabric used, and

3 a bar chart to explain the germicidal effect of the item of laundry acc. 1

In 1 is a piece of underwear 1 shown that the inside can be brought into contact with the skin of the laundry user 2 and an outside facing away from it 3 having. As from the enlarged section in 1 becomes clear, there is the underwear piece 1 thereby from a tissue 4 , which in the usual way from weft and warp threads 5 . 6 is formed. As now in this enlargement by longitudinal dashes indicated and in 2 each thread is explicitly shown 5 . 6 a metal coating enveloping it 7 made of silver on the individual threads in a dipping process 5 . 6 of the fabric 4 has been permanently and wash-resistant anchored. The strings 5 . 6 are on all sides of the metal coating 7 surround. Here is the thickness of the metal coating 7 so to the diameter of the threads 5 . 6 matched that the metal coating 7 a weight fraction of about 20% of the total weight of the fabric 4 having. The strings 5 . 6 themselves are preferably made of polyamide, but other thread materials, in particular polymers, can also be used.

A piece of underwear equipped in this way 1 exhibits - as mentioned - bactericidal, fungicidal or generally antimicrobial properties when worn on the skin. The mechanism of action is explained by the fact that positively charged silver cations in the skin environment are caused by the germs that carry an electronegative charge from the metal coating 7 can be absorbed. A reaction with the protein of the germ then leads to its denaturation and killing. As a result, a kind of "self-sterilization" of the skin takes place constantly, irritated or diseased areas of the skin can recover in peace, and itching that often occurs can also be stopped. With such items of laundry, medicinal treatments can sometimes be avoided with a favorable healing process.

The above mechanism has been demonstrated experimentally. So shows 3 an experiment in which in three sample containers, each with 100 ml of a test solution with an initial germ infestation of almost 10,000,000 (1.0 E + 07) CFU / ml (CFU = colony-forming units), samples of a silver-coated tissue with a mass of 1 g (left Bar A) or 0.1g (middle bar B) was added and the sample was left to stand in parallel (right bar C). The bar chart now shows the decrease in the number of bacteria over 8 days. In the sample container with the 1 g sample piece (bar A), the number of germs decreased rapidly to 0 within 4 days. In the sample container with the 0.1 g sample piece (bar B), the decrease in the number of bacteria was slower, the sample being germ-free after 7 days. In the so-called "positive control", ie a sample solution left to itself, the bacterial count decreased from just under 10,000,000 CFU / ml to just over 100,000 germs per ml. This makes the effectiveness of the silver-coated tissue clear.

As Alternatively, the shown underwear can also be knitted or knitted his. Such material can also metallized fitted sheets, socks or gloves are made that are pillow cases and duvet covers usually woven.
