Kind code of ref document : A1. Effective date : Ref country code : DE. Ref legal event code : The present invention is an antimicrobial material consisting of a carrier polymer to which metallic and non-metallic cations are bonded, a process for its preparation and its use.

Over the past decade, a number of antimicrobial materials have been developed that are not used in medicines. Some of these materials are coatings of metallic ions that are applied to the surface of equipment. Others form a sharp-edged micro-surface that can destroy bacterial cells through mechanical interactions. However, silver products including nanosilver have found little entry into industrial practice because of their high price.

Also, the washing resistance of such products is discussed. So describes CN an antiseptic and deodorant fiber consisting of a a polyacrylonitrile terpolymer made from acrylonitrile first monomer , methyl acrylate second monomer and sodium allyl sulfonate or itaconic acid third monomer , b copper ions, and c malachite green IV. The latter two Components are attached to the polyacrylonitrile through noncovalent interactions. On the other hand, antimicrobial materials in which the antimicrobial components are not directly attached to the material have a significant disadvantage: the antimicrobial components may diffuse out of the material or be washed out.

The result is a decrease in antimicrobial activity and an uncontrollable spread of this activity in the environment of the material. In addition, fibers and fabrics made of materials that are washed frequently lose their antimicrobial effectiveness very quickly. This also applies to some extent to the fiber of the CN to. This compound is used for antimicrobial finishing of textiles.

Their binding to the material takes place via the silane. According to the manufacturer, the antimicrobial effect is based on the fact that the C18 chain contained in the molecule interacts with the cell membrane and the contact thereby produced between the cationic nitrogen atom and the cell leads to the destruction of the cell.

In nonwovens and felts "nonwovens" , the control of microorganisms is of particular importance, since these materials are frequently used in the medical field. Thus, the suppression of microorganisms in "nonwovens" is important not only for medical applications, but also for such nonwovens or felts used in garments and housewares such. Nonwovens protect young plants from pests and cold in fields, and as geotextiles they separate earth layers and bulk solids. Nonwoven fabrics are used as backing material for carpets, textile interior linings adapted to the shapes of cars, and roofing membranes.

Nonwovens have a fundamental advantage: Even in the first step, it is possible to produce textile fabrics from fibers. As a result, nonwovens differ from woven and knitted fabrics, since these depend on a preliminary stage, namely the production of threads or yarns.

Nonwovens can therefore be produced comparatively inexpensively. The majority of the known antimicrobial materials contain either only metal ions or only non-metal ions bound to the material. These materials are inevitably missing the cooperative antimicrobial effect of metallic with non-metallic ions. There is therefore a need for a new antimicrobial material with improved properties, on the one hand has a durable high antimicrobial activity, shows little tendency to wash out and on the other hand is characterized by ease of preparation, handling and processing.

So far, none of the known products met all the requirements that are placed on such a product. The invention relates to an antimicrobial material consisting of a carrier polymer to which metallic and non-metallic cations are bonded. By contrast, most of the known antimicrobial materials contain either only metal ions or only non-metal ions bound to the material.

This cooperative antimicrobial effect of metallic with non-metallic ions is surprising and could not be deduced from the prior art. Surprisingly, the high diffusion resistance of the new materials avoids a decrease in antimicrobial activity and an uncontrollable spread of this activity in the environment of the material.

Moreover, fibers and webs of materials of the present invention that are washed frequently do not lose their antimicrobial efficacy. Both the metal cation and the non-metallic cation have an antimicrobial function; Together they give the antimicrobial material of the invention the ability to kill microorganisms. In the following, some of the terms used are defined and explained. These terms refer to any type of chemical interaction, whether covalent, ionic, nonionic or hydrophobic, which results in cohesion between the carrier polymer and the metallic or non-metallic ions, respectively.

The "linking" of metallic ions with the carrier polymer is particularly due to the fact that the nitrile groups of the first carrier polymer monomer complex the metal ions, thereby "bonding" the latter to the carrier polymer. Accordingly, "linking" the non-metallic cations with the carrier polymer means that the acid groups of the third carrier polymer monomer form ionic interactions with the non-metallic cations or covalent bonds are formed between the non-metallic cations and the acid groups.

This leads to "binding" of the non-metallic cations to the carrier polymer. In contrast, the attachment of the cations to the carrier polymer does not expressly imply that salts of the metallic or non-metallic cations with another low molecular weight, non-polymeric organic or inorganic compound are merely embedded in a matrix of carrier material such that the binding of the cations is by physical Effects inclusion of cations in the matrix.

A "polyacrylonitrile" PAN in the context of the present application is an organic polymer which is partially or wholly composed of acrylonitrile monomers. In addition to acrylonitrile, polyacrylonitrile may also contain other monomers, for example substituted ethylenes and acrylic acids or acrylic esters. So For example, a ternary PAN according to the present invention consists of three different monomers, one of which is acrylonitrile. A "derivative" in the context of the present invention is a compound which derives from a basic structure in that one or more hydrogen atoms in this basic structure has been replaced by an atomic group.

However, the derivative is still characterized by the originally present functional groups. For example, e. One of these styrene derivatives is a styrene which carries at least one acid group preferably a sulfonic acid or carboxylic acid group on the benzene ring.

Characteristic of textiles is that they consist of fibers and are usually much more extensive in two dimensions than in a third dimension they are therefore usually flat and thin. Textiles may well have a certain thickness, as is the case with textile finished goods including carpets, velvet, plush, terry cloth, nonwovens or felt.

Textiles are classified according to their designation into clothing, "home textiles" textiles for the home and "technical textiles" textiles for industrial purposes. Basic method of making yarn is spinning. In the production of textile finished goods, the processes dominate weaving, knitting, bonding to nonwoven fabric or felt and knitting. A "nonwoven" or "nonwoven fabric" is a textile fabric made of individual fibers.

In contrast, fabrics, knits and knits are made from yarns and membranes are made from films. In the context of the present application, however, felts should also be covered by the term "nonwovens" or "nonwovens" unless expressly different. A fleece in the narrower sense consists of loosely connected fibers, which are not yet connected to each other. The strength of a fleece is based only on the fiber's own liability. To be able to process and use the fleece, it must be solidified, for which various methods can be used.

Only a solidified fleece is actually to be designated as nonwoven fabric. In the following, however, the term "nonwoven" is intended to mean both loose nonwoven and nonwoven. The nonwoven production is achieved by mechanical needling or hydroentanglement , chemical addition of binders or thermal thermobonding solidification of fiber webs for details see.

Albrecht, W. A "yarn" is a long, thin structure of several fibers. It is a textile intermediate, which can be processed into woven, knitted and knitted or used for sewing. Yarn is made directly by wet or dry spinning or twisted after spinning.

Preferred yarn in the context of the present application is a staple fiber yarn. The inventive material according to embodiments 1 to 3 has a long-term antimicrobial and mold-resistant broad-spectrum effect. It has a broad spectrum of activity on various microorganisms. This antimicrobial effect is achieved by the synergy of the metallic with the non-metallic ions, which are bound to the carrier material.

The material can be used to make antimicrobial and mildew resistant plastics, ceramics, building coatings, rubbers, etc. The material is non-toxic, environmentally friendly, easy to manufacture and easy to handle.

The material according to embodiments 1 to 3 consists of a carrier polymer and cations bound thereto which, however, do not alter the typical properties of the carrier polymer. The composition of the polymer ensures a stable anchoring of the ions on the carrier polymer, which results in the high resistance to washing and diffusion resistance of the material according to the invention compare example 3 and example 8.

In a preferred aspect of the present invention, the first monomer unit "first monomer" of the carrier polymer has the formula. In a second preferred aspect, the second monomer unit "second monomer" is a C alkyl ester of an acid selected from the group consisting of acrylic acid, methacrylic acid and crotonic acid. Preferably, it is methyl or ethyl acrylate, more preferably methyl acrylate. In a third preferred aspect, the third monomer has the formula. In a particularly preferred aspect, the third monomer is a styrene derivative having at least one acid group, and preferably, this free acid styrenic derivative has the formula.

In these aspects, the term "C alkyl group" includes methyl, ethyl, n-propyl, isopropyl, butyl, n-butyl, iso-butyl and amyl n, 2, 3, 3 , or neo-amyl. Preferred are halo C alkyl groups. Particularly preferred is an embodiment of 1 in which these three preferred aspects are fulfilled simultaneously, ie the carrier polymer consists of the monomers defined under the first to third aspects.

Most preferably, the carrier polymer consists of the three monomers acrylonitrile, methyl acrylate and sodium styrylsulfonate. Particularly preferred is a composition having from about 93 to about 94 weight percent first monomer, about weight percent second monomer, and more than 0 weight percent but less than 1 weight percent third monomer.

The copolymer may be a random or block polymer or a mixture of these two types of polymers. When the copolymer is a block polymer, an AB-type or ABA-type block polymer in which the A block consists of the first monomer and the B block is a random copolymer consisting of the second and the third monomer.

The non-metallic cations are preferably non-metallic cations with antimicrobial property, more preferably nitrogen-containing cations with antimicrobial property, particularly preferably cations with a tertiary or quaternary nitrogen atom, especially cationic dyes.

Both the metallic and the non-metallic cations in the material according to the invention may either be composed only of one kind of cations or be mixtures of different metallic or non-metallic cations. However, the material contains at least one kind of metallic and one kind of non-metallic cations, preferably only one kind of metallic and one kind of non-metallic cations.

The non-metallic cations having antimicrobial property are preferably nitrogen-containing compounds having at least one positive charge. It may be any antimicrobial aliphatic or aromatic amine or ammonium compound. These cations include saturated or unsaturated heterocycles which are either protonated or have at least one positive charge from the outset. They contain at least one nitrogen atom and are selected from the group comprising saturated heterocycles such as pyrrolidine, imidazolidine, piperidine, piperazine, azepane, azepine, morpholine, DABCO 1,4-diazabicyclo [2.

Dyes, phthalocyanine dyes, perinone dyes, naphthalimide dyes, quinophthalone dyes, neutrocyanine dyes, nitro dyes, etc. Particularly preferred non-metallic cations are the cited cationic dyes, in particular methine dyes, diazo dyes and triphenylmethane dyes, of which Basic Green dyes including Basic Green 1 [N, N-diethyl [p- diethylamino -] diphenylmethylene] -2,5-cyclohexadienylidene ammonium hydrogen sulfate] Brilliant Green, Malachite Green G, CAS No.

In order for the material of the invention to have antimicrobial properties and to be mold-resistant, it is essential that its content of non-metallic cation is not too low, i. The latter would be e.

According to the invention, the non-metallic cation is then present only in traces if its content in the material according to the invention is less than 0.

The most significant feature of nonwoven fabric is made directly from fibers in a continuous production line. While manufacturing nonwovens, some conventional textile operations, such as carding, drawing, roving, spinning, weaving or knitting, are partially or completely eliminated. For this reason the choice of fiber is very important for nonwoven manufacturers. The commonly used fibers include natural fibers cotton, jute, flax, wool , synthetic fibers polyester PES , polypropylene PP , polyamide, rayon , special fibers glass, carbon, nanofiber, bi-component, superabsorbent fibers. Raw materials have not only delivered significant product improvements but also benefited people using these products by providing hygiene and comfort.

History of clothing and textiles

The study of the history of clothing and textiles traces the development, use, and availability of clothing and textiles over human history. Clothing and textiles reflect the materials and technologies available in different civilizations at different times. The variety and distribution of clothing and textiles within a society reveal social customs and culture. The wearing of clothing is exclusively a human characteristic and is a feature of most human societies, though it is not known exactly when various peoples began wearing clothes.

It is used in fine-grade wool en fabrics. Although linen and wool blends are occasionally made today, the use of finer finishing techniques makes them extremely comfortable and the name linsey- wool sey is limited to historical references.

This application also claims priority from German application DE 10 The entire contents of that international application and that German application and that European application are incorporated herein by reference. The object of the present invention is a felt material with a barrier function comprising at least one felt layer and an absorber containing material, as well as a method for the production of the felt material, a component made of this felt material and its use. Felt is a fabric for textiles which has a sheet-like structure and which consists of mechanically bonded fibers. Unlike other fabrics, felt is not woven. Instead, it is manufactured under the influence exerted by pressure with the procedure for pressed felts, or by using an acid to roughen the fibers and to create a nonwoven fabric which is bonded by moisture and heat. Traditionally, pressed felts are made from wool or from other loose animal hair because due to the peeling structure of the hair, the fibers become mutually entangled. The hardness of the felt can range between that of soft cotton or of hard wood, and felts which have even a higher hardness can be also produced. The classical wool felts are also referred to as pressed or milling felts.

The subject-matter in this little book is the substance of a series of Lectures delivered before the Hat Manufacturers' Association in the years and About this period, owing to the increasing difficulties of competition with the products of the German Hat Manufacturers, a deputation of Hat Manufacturers in and around Manchester consulted Sir Henry E. Roscoe, F. Sir Henry Roscoe recommended the writer, then the Lecturer on Chemical Technology in the Owens College, as lecturer, and he was accordingly appointed. The lectures were delivered with copious experimental illustrations through two sessions, and during the course a patent by one of the younger members became due, which proved to contain the solution of the chief difficulty of the British felt-hat manufacturer see pages This remarkable coincidence served to give especial stress to the wisdom of the counsel [Pg vi] of Sir Henry Roscoe, whose response to the appeal of the members of the deputation of was at once to point them to scientific light and training as their only resource. In a letter recently received from Sir Henry , he writes: "I agree with you that this is a good instance of the direct money value of scientific training, and in these days of 'protection' and similar subterfuges, it is not amiss to emphasise the fact. It is thus gratifying to the writer to think that the lectures have had some influence on the remarkable progress which the British Hat Industry has made in the twenty years that have elapsed since their delivery.
