Abstract

Cleaning textile, comprising at least one layer, the layer comprising microfibers. The microfibers are biodegradable.

Description

Technical field

The invention relates to a cleaning textile comprising at least one layer, the layer comprising microfibers.

State of the art

Such a cleaning textile is generally known.

If necessary, the cleaning textile is constructed in several layers and comprises, for example, two cover layers, between which a comparatively voluminous intermediate layer is arranged.

The use of microfibers in cleaning textiles has proven itself well. The microfibers ensure good cleaning performance during the intended use of the cleaning textile.

However, it should be noted that the microfibers remain in the environment after the useful life of the cleaning textile and thus pollute the environment.

For example, it was found that the world's oceans are also significantly polluted by plastic waste and especially by microplastics.

Very small plastic elements can get into the human body via the food chain.

Microplastics mean plastic elements smaller than 5 mm, including microfibers made of plastic.

Presentation of the invention

The invention has for its object to develop a cleaning textile of the known type such that it is manufactured in an environmentally friendly manner and can also be disposed of in an environmentally friendly manner after its use.

This object is achieved by a cleaning textile according to claim 1.

Advantageous embodiments are referred to in the claims, which are directly or indirectly related to claim 1.

To achieve the object, a cleaning textile is provided, comprising at least one layer, the layer comprising microfibers that are biodegradable.

• Materialien werden als biologisch abbaubar bezeichnet, wenn sie durch Mikroorganismen, bzw. Enzyme z. B. im Boden abgebaut werden. Der Abbau erfolgt im Wesentlichen durch Oxidations- und Hydrolyseprozesse zu den Spaltprodukten Wasser, Kohlendioxid und Biomasse.

In this context, “biodegradable” means the following:

• Materials are called biodegradable if they are broken down by microorganisms or enzymes, e.g. B. degraded in the ground. The degradation takes place essentially through oxidation and hydrolysis processes to the fission products water, carbon dioxide and biomass.

Biodegradability refers to the ability of organic chemicals to be biodegraded, i.e. by living things (especially saprobionts) or their enzymes. Ideally, this chemical metabolism runs completely through to mineralization, so that the organic compound is broken down into inorganic substances such as carbon dioxide, oxygen and ammonia, but the degradation can also stop with transformation products that are stable in degradation.

Industrially manufactured chemicals are considered to be biodegradable if they are removed from the environment through biodegradation and added to the mineral cycle.

According to an advantageous embodiment, it can be provided that the microfibers consist of a renewable raw material.

A renewable raw material is an organic raw material that comes from agricultural or forestry production.

In connection with the claimed cleaning textile, renewable raw materials of vegetable origin are used. The use of renewable raw materials often minimizes the impact on the environment during the manufacture of the cleaning textile. Together with the biodegradability of the microfibers, the environmental impact is also reduced to a minimum even when the cleaning textile is subsequently disposed of after it has been used as intended.

According to an advantageous embodiment, it can be provided that the at least one layer is designed as a cleaning layer and consists entirely of microfibers from a biodegradable and / or renewable raw material. As a result, the environmental pollution described above is largely reduced.

Viscose, from which the microfibers are made, can be used as a biodegradable and renewable raw material. Viscose fibers are man-made fibers from regenerated cellulose, the production of viscose fibers being state of the art. For example, viscose fibers are produced by a wet spinning process.

Cellulose is a main component of plant cell walls, therefore a renewable raw material and available in large quantities in nature.

The raw material for viscose fibers is cellulose, which comes from wood from trees.

In addition to viscose, there are other renewable raw materials that can be used in the manufacture of cleaning textiles.

The raw material "viscose" is particularly advantageous because it is highly hydrophilic.
