Abstract

The absorbent material, has a textile carrier layer of a large tubular knit, and an absorption layer with hydrophobic pile loops as a fluid carrier layer (T). It is coated (B) in a reverse/transfer action with at least two layers as a cover and a bonding layer, in a compact, hydrophilic and breathable but waterproof polyurethane. The absorbent material is coated (B) in a reverse/transfer action with at least two layers as a cover and a bonding layer, in a compact, hydrophilic and breathable but waterproof polyurethane. Alternatively, the fabric can be laminated with a film of polyurethane, polypropylene (PP), polyethylene (PE), polyether sulfone (PES), polytetrafluoroethylene (PTFE) or polyether block amide. The large tubular knitted fabric is a single jersey with a bonding yarn lining in a fabric weight of 200-600 g/m<2> and pref. 380 g/m<2>. A filament yarn is used for the pile loops, using texturized PP or PES, in a float binding. The piles have a height of 0.5-3.0 mm and preferably 1.0-1.5 mm. The fluid barrier supports \-1 m water column and preferably \-3 m. The capacity of the buffer/absorption layer (S) for water is \-400 ml/m<2> and pref. \-624 ml/m<2>. The breath ability/steam permeability is \-200 ml/m<2>/day and pref. \-500 ml/m<2>/day. The polyurethane cladding layer, such as of Impraperm (RTM; hydrophilic polyurethane), has a material weight of 25-130 g/m<2> and pref. 40-60 g/m<2>, giving a dry weight for the cover and bonding layers each of 25 g/m<2> \!20%. The polyurethane cladding is a compact and hydrophilic polyurethane with a solvent base or as a watery dispersion. The edges of the compound textile material are stitched round tightly with a hydrophobic and texturized yarn. Any seams in the material are stitched with yarns which swell, preferably with a twisted PES core and a cotton mantle. An additional insert is used when the material is for incontinence underpants.

Technisches GebietTechnical field

Textiles, mehrfachverwendbares Hilfsmittel zur Absorption von Harn bei Inkontinenz.Textile, reusable tool for Absorption of urine in incontinence.

Zugrundeliegendes Problem und Stand der TechnikUnderlying problem and state of the art

In Deutschland leben zur Zeit über 2 Mio. Inkontinente im Alter < 65 Jahren (in der Mehrzahl Männer), davon ca. 400 000 in Pflegehei­ men. Zusätzlich gibt es ca. 1.7 Mio Inkontinente im Alter von 5 bis 65 Jahren, in der Mehrzahl Frauen.There are currently over 2 million incontinents aged <65 living in Germany Years (mostly men), of which approx. 400,000 were in nursing care men. In addition, there are approximately 1.7 million incontinents aged 5 to 65 years, mostly women.

Inkontinente bettlägrige Personen benötigen eine Krankenunterlage, die zwecks Einsparung von Kosten gewaschen, also vielfach ver­ wendet werden sollte, in der Oberfläche zwecks Trockenhaltung der Haut den Harn schnell vom Körper wegleitet, darunter eine absorbie­ rende Puffer-/Sorptionsschicht aufweist und nach unten zwecks Ma­ tratzenschutz eine wasserdichte Sperre hat, die idealerweise atmungs­ aktiv also wasserdampfdurchlässig ist, um kein Schwitzen zu stimu­ lieren. Noch mobile inkontinente Personen sind in ihren gesellschaft­ lichen Kontakten deutlich eingeschränkt. Sie müssen vorsorgen. Das Tragen von Windeln oder Windelhosen mit Einlagen wird oft als nicht altersgemäß abgelehnt, besonders wenn es in unerwünschtem Maße aufträgt, und die eingesetzten PE-, PP- bzw. PVC-Folien bei Bewegung rascheln oder knistern. Auch häufig fehlender Tragekom­ fort durch hinderliche Wülste und Nähte bedeutet eine Behinderung der Mobilität. Ein beschichtetes Textil, das all diese Anforderungen gleichzeitig erfüllt, ist bisher nicht vorhanden. Allenfalls ein Teil der Anforderungen wird bereits erfüllt bei den Produkten, die in anderen Patenten/-anmeldungen beschrieben sind, und zumindest den Ein­ malwindeln vorzuziehen sind. Es handelt sich um wiederverwendbare Windelhosen aus einem Verbundstoff (1.), der aber keine nennens­ werten Pufferkapazitäten aufweist und mit der Beschichtung zum Körper hin getragen wird, bzw. um ein aus verschiedenen zusammen­ gesetzten Einzellagen (u. a. Laminaten) aufgebautes Textil (2.), bei dem poröse Membranen eingesetzt sind, die sich prinzipiell zusetzen können und eine begrenzte Elastizität haben. Die weiteren textilen Lagen müssen wie bei der Vielzahl der aus reinen Textilien (ohne Be­ schichtung) aufgebauten wiederverwendbaren Windelhosen vernäht werden. Einmalwindeln verursachen gegenüber den wiederverwend­ baren Windelhosen deutlich höhere kosten Kosten (ca. 300-500 Mio DM jährlich in Deutschland) und ein stetig wachsendes Müllproblem, da auch die verstärkt in Einmalwindeln eingesetzten Superabsorber biologisch nur sehr langsam abgebaut werden.Incontinents bedridden people require a medical record, washed for the purpose of saving costs, so ver should be used in the surface to keep the Skin quickly directs urine away from the body, including absorption has buffer / sorption layer and down for Ma Tratzenschutz has a waterproof barrier that is ideally breathable active, so it is permeable to water vapor to prevent sweating lieren. There are still mobile incontinent people in their society contacts significantly restricted. You have to make provisions. The Wearing diapers or nappy pants with inserts is often considered not declined according to age, especially if it is in undesirable Applies dimensions, and the PE, PP or PVC films used Rustle or crackle movement. Often missing comfort away from bulging bulges and seams means a disability of mobility. A coated textile that meets all of these requirements fulfilled at the same time is not yet available. At least part of the Requirements are already met for the products in others Patents / applications are described, and at least the one coloring diapers are preferable. It is reusable Diaper pants made of a composite (1.), but no mention value buffer capacities and with the coating for  Body is carried out, or to put together from different set individual layers (including laminates) built-up textile (2.), with porous membranes are used, which clog in principle can and have a limited elasticity. The other textiles As with the large number of pure textiles (without loading layered) of reusable diaper pants become. Disposable diapers cause reuse over those diaper pants cost significantly more (approx. DM 300-500 million annually in Germany) and a constantly growing waste problem, since also the superabsorbers used increasingly in disposable diapers biodegradable only very slowly.

Beschreibung der ErfindungDescription of the invention

Es war Ziel der vorliegenden Erfindung, einen textilen Verbundstoff zu schaffen, der bei Inkontinenz, unfreiwilligem Harnabgang, sowohl bei bettlägrigen immobilen Betroffenen als Krankenunterlage, sau­ gende Bettschutzeinlage, als auch in Verwendung für eine waschba­ re, mehrfachverwendbare Windelhose folgende Aufgaben erfüllt:
It was the aim of the present invention to create a textile composite which, in the case of incontinence, involuntary urine leakage, both for bedridden immobile sufferers as a medical pad, vacuuming bed protection insert and also for use in a washable, reusable diaper pants fulfills the following tasks:

  • - Schneller Wegtransport des Harns von der Haut und Rücknässe­ schutz, geringe Sorptionszeiten- Rapid transport of urine away from the skin and wet back protection, low sorption times
  • - Absorption von Harn, Puffer mit einer Kapazität < 624 ml/m2, wie im Hilfsmittelverzeichnis, Produktgruppe 19, gefordert (3.)- Absorption of urine, buffer with a capacity <624 ml / m 2 , as required in the list of medical devices, product group 19 (3.)
  • - Nässesperre auf der der Haut abgewandten Seite bei gleichzeitiger hoher Atmungsaktivität (Wasserdampfdurchlässigkeit)- Moisture barrier on the side facing away from the skin with simultaneous high breathability (water vapor permeability)
  • - Waschbarkeit bei zumindest 40°C und ggf. Desinfizierbarkeit- Washability at at least 40 ° C and disinfectability if necessary
  • - Hohe Haftfestigkeit im Verbund zwischen absorbierender Schicht und Beschichtung/Nässesperre- High adhesive strength in the bond between the absorbent layer and coating / moisture barrier
  • - Weiches, elastisches Material, das nicht bzw. kaum aufträgt- Soft, elastic material that does not or hardly applies
  • - Flüssigkeitsdichte Randgestaltung bei Druckbelastung- Liquid-tight edge design under pressure
  • - Hautverträgliches Material.- Skin compatible material.

All diese Anforderungen werden von der vorliegenden Erfindung, Fig. 1, Erfindung erfüllt. Als textiler Träger des Verbundstoffes dient ein Großrundgestricke der Bindung rechts/Links-Bindefadenfutter, das gegenüber Frottiergewirken den Vorteil der niedrigeren Polhöhe, besitzt (4.). Es besitzt auf der Polseite eine optimale Feuchtetransport­ schicht "T" (Fig. 1), die im Verbundtextil zum Körper/Haut ausge­ richtet ist. Die Wasseraufnahmekapazität der Sorptionsschicht "S" (Fig. 1) von < 700 ml/m2 bei einem Flächengewicht von 380 g/m2 erfüllt die Anforderungen an Inkontinenzunterlagen (3.). Die den Polschlingen gegenüberliegende Seite des Bindefadenfuttergestricks ist im Vergleich zu doppelseitigen Polgewirken und auch zu einseiti­ gen Polgewirken sehr glatt und eignet sich daher zwecks Nässesper­ re besonders für eine Beschichtung "B" (Fig. 1) mit kompaktem Poly­ urethan im Transferverfahren (Umkehrbeschichtung). Im Gegen­ satz zu einer Direktbeschichtung kann die Beschichtungsmasse dabei kaum in das Textil eindringen, wodurch der Verbund weich bleibt, die vom Textil und der Beschichtungsmasse vorgegebene Elastizität erhalten bleibt, und das Bindefadenfuttergestrick und damit der ge­ samte Verbund eine hohe Speicherkapazität behält.All of these requirements are met by the present invention, FIG. 1, invention. A large circular knitted fabric of the right / left binding thread lining serves as the textile carrier of the composite, which has the advantage of lower pile height compared to terry fabrics (4.). It has on the pole side an optimal moisture transport layer "T" ( Fig. 1), which is aligned in the composite textile to the body / skin. The water absorption capacity of the sorption layer "S" ( Fig. 1) of <700 ml / m 2 at a basis weight of 380 g / m 2 meets the requirements for incontinence pads (3.). The opposite side of the pile loops of the knitted twine lining is very smooth compared to double-sided pile fabrics and also to one-sided pile fabrics and is therefore particularly suitable for the purpose of moisture barrier for a coating "B" ( FIG. 1) with compact polyurethane in the transfer process (reverse coating). In contrast to a direct coating, the coating composition can hardly penetrate the textile, as a result of which the composite remains soft, the elasticity specified by the textile and the coating composition is retained, and the knitted thread lining knit and thus the entire composite retains a high storage capacity.

Für die Beschichtung eignen sich hydrophile Polyurethane, z. B. Impraperm, Bayer AG, Leverkusen, auf Lösungsmittelbasis oder aus wäßrigen Dispersionen. Es werden zwei Striche vorgegeben, Deck­ strich und Haftstrich. In letzteren fließt das Trägertextil unter nur ge­ ringem Andruck ein. Atmungsaktivität und Quellung des Verbundes werden bestimmt von der Auswahl des Polyurethans.Hydrophilic polyurethanes, e.g. B. Impraperm, Bayer AG, Leverkusen, solvent-based or from aqueous dispersions. Two lines are given, deck dash and line. In the latter, the carrier textile flows under only ge ring pressure. Breathability and swelling of the composite are determined by the choice of polyurethane.

Die Randgestaltung der Flächenware erfolgt über dichte Kettelung mit einem hydrophoben, texturierten PES-Faden, der wie die PP-Polschlingen einen Rücknässeschutz bewirkt.The edge design of the surface goods is done by tight linking with a hydrophobic, textured PES thread like that PP pole loops provide protection against rewetting.

Eine Berührung mit der Haut der Betroffenen erfolgt allein über die Polschlinge (Transportschicht) des Trägertextils aus texturiertem PP-Filamentgarn. Eine solche Oberfläche wird z. B. auch von der Haut von Atopikern gut vertragen (5.)Contact with the skin of the person concerned takes place solely via the Pole loop (transport layer) of the carrier textile made of textured PP filament yarn. Such a surface is e.g. B. also from the skin well tolerated by atopics (5.)
