Description

Die Erfindung betrifft ein Verfahren zum Verfestigen und Versteifen von textilen Produkten, vorzugsweise Vliesstoffen aus pektinhaltigen Faser­ stoffen durch Erweichen der Pektinkomponente mittels geeigneter Erwei­ chungsmittel, wobei während der Entfernung dieser Stoffe die Pektinschicht aushärtet und kontaktierende Fasern miteinander verbindet.The invention relates to a method for solidifying and stiffening textile products, preferably nonwovens made of pectin-containing fiber substances by softening the pectin component by means of suitable softening agents detergent, whereby during the removal of these substances the pectin layer hardens and connects contacting fibers.

Bei der Vlies­ verfestigung sind allgemein mechanische, chemische und thermische Ver­ fahren bekannt. Bei der mechanischen Verfestigung unterscheidet man Ver­ nadelung mit Hilfe von Filznadeln, Faserverschlingungen durch Wasser­ strahlen (spunlaced) oder Nähwirkverfahren ohne Faden. Der Verfestigungs­ grad ist bei diesen Verfahren relativ gering; zur Erzielung höherer Festigkeiten erfolgt die Einarbeitung von Verstärkungsgeweben oder eine zusätzliche chemische Verfestigung. Naturfasern wie Jute, Flachs und Hanf lassen sich nur eingeschränkt bis zu einem gewissen Grad vernadeln; das Nadelverfahren ist hier nur bedingt zur Verfestigung geeignet. Der größte Teil der Vliesstoffe wird chemisch verfestigt. Mittels Vollbad-Impräg­ nierung, Sprühverfestigung, Pflatschen oder Schaumverfestigen wird dabei ein Mittel zugegeben, das nach der Behandlung die einzelnen Fasern stoff­ lich verbindet. Der Nachteil dieser Verfahren ist, daß ein zusätzlicher Stoff, nämlich das Bindemittel erforderlich ist. Bei der thermischen Ver­ festigung werden thermoplastische Faserstoffe unter der Einwirkung von Hitze erweicht und miteinander in Kontakt stehende Faserteile verklebt. Der Nachteil dieses Verfahrens ist, daß hierfür nur thermoplastische Fasern geeignet sind und durch die Deformierung und Verklebung der Fasern ihr Fasercharakter zerstört wird. Als pektinhaltige Faserstoffe gelten Naturfaserstoffe wie beispielsweise Flachs oder Hanf. Die Fasern werden dabei von Pektin (Pflanzenleim) umhüllt, der bei Zimmertemperatur und im trockenen Zustand ein Stoff von fester Konsistenz ist. Ein mäßiges Be­ netzen der Faseroberfläche solcher pektinhaltiger Faserstoffe, im einfach­ sten Fall mit kaltem oder warmem Wasser, dem unter Umständen Netzmittel zugesetzt sein können, erweicht diese Pektinschichten soweit, daß ohne oder unter Wirkung eines nur mäßigen äußeren Drucks sich diese durch­ dringen und eine stoffliche Brücke zwischen den vormals unverbundenen Naturfasern bilden. Nach dem Entfernen des Erweichungsmittels, bei wäß­ rigen Systemen wäre es eine einfache Trocknung, wirkt das nun wieder feste Pektin als Bindemittel zwischen den vormals unverfestigten Fasern. Es entsteht in Abhängigkeit zum vorhandenen Pektinanteil, der Erwei­ chungsintensität und der Wirkung eines äußeren Drucks ein verfestigtes, textiles Produkt mit reduzierter Haarigkeit und höherer Steifheit. Insbesondere bei ungerösteten Stengelfasern ist der Pektinanteil in einer Höhe vorhanden, daß er sich als Verfestigungs- und Versteifungsmittel für textile Produkte sehr gut ausnutzen läßt. So wird der Pektin- und Hemicelluloseanteil eines ungerösteten Flachses in "Textilveredlung" 6/1987, S. 220-223 mit 20% angegeben. Aber auch geröstete Stengelfasern besitzen noch Pektinanteile von 7 bis 8% bei Flachs ("Naturfasern/­ Chemiefasern", Fachbuchverlag Leipzig 1955; "Melliand Textilberichte 11/1990, S. 825 bis 830) und etwa 10% bei Hanf ("Naturfasern/Chemiefa­ sern", Fachbuchverlag Leipzig 1955), die für Verfestigungs- bzw. Verstei­ fungszwecke nutzbar sind.With the fleece consolidation are generally mechanical, chemical and thermal ver drive known. A distinction is made between mechanical strengthening and ver needling with the help of felting needles, fiber entanglements through water blasting (spunlaced) or sewing process without thread. The consolidation degree is relatively low in these processes; to achieve higher Reinforcement fabrics or a strength is incorporated additional chemical consolidation. Natural fibers such as jute, flax and hemp can be needled to a certain extent only to a limited extent; the The needle method is only suitable for solidification here to a limited extent. The biggest Some of the nonwovens are chemically consolidated. Using a full bath imprint nation, spray hardening, splashing or foam hardening added an agent that the individual fibers after treatment Lich connects. The disadvantage of this method is that an additional one Substance, namely the binder is required. In the thermal Ver consolidation thermoplastic fibers under the influence of Heat softens and glues fiber parts in contact. The disadvantage of this method is that it is only thermoplastic Fibers are suitable and due to the deformation and bonding of the fibers their fiber character is destroyed. The following are considered pectin-containing fibers Natural fiber materials such as flax or hemp. The fibers are thereby covered with pectin (plant glue), which at room temperature and in dry state is a substance of firm consistency. A moderate loading wetting the fiber surface of such pectin-containing fibers, simply The best case is with cold or warm water, which may be a wetting agent can be added, these pectin layers soften to the extent that without or under the effect of only moderate external pressure penetrate and a material bridge between the previously unconnected Form natural fibers. After removing the emollient, with aq systems, it would be a simple drying, if it is now solid again Pectin as a binding agent between the previously unconsolidated fibers. It arises depending on the amount of pectin present intensity and the effect of an external pressure  textile product with reduced hairiness and higher stiffness. Especially with unroasted stem fibers, the pectin content is all in one Height available that it can be used as a strengthening and stiffening agent for makes very good use of textile products. So the pectin and Hemicellulose share of an unroasted flax in "textile finishing" 6/1987, pp. 220-223 with 20%. But also roasted stem fibers still have 7 to 8% pectin in flax ("natural fibers / Chemical fibers ", specialist book publishing house Leipzig 1955;" Melliand textile reports 11/1990, pp. 825 to 830) and about 10% for hemp ("Natural fibers / Chemiefa sern ", Fachbuchverlag Leipzig 1955), for consolidation or reinforcement are usable.

Das Verfahren kann bei textilen Produkten, insbesondere Vliesstoffen mit pektinhaltigen Faseranteilen, dazu genutzt werden, um
In the case of textile products, in particular nonwovens with pectin-containing fiber components, the method can be used to:

  • - Textilien zu verfestigen,- solidify textiles,
  • - Textilien zu verdichten,- compress textiles,
  • - Textilien oberflächlich zu glätten (beispielsweise um die Haarigkeit zu reduzieren),- Smooth textiles on the surface (for example to reduce hairiness)
  • - Textilien zu versteifen,- stiffen textiles,
  • - Textilien in einer permanenten Form zu fixieren,- to fix textiles in a permanent shape,
  • - als Bindefasern in Textilmischungen zu fungieren,- act as binding fibers in textile blends,
  • - eine derartige Textilie mit anderen Textilien zu verbinden (beispielsweise zur Ausbildung von Sandwichstrukturen).- to combine such a textile with other textiles (for example to form sandwich structures).

Der Vorteil des Verfahrens liegt in der Nutzung des naturgegebenen Pektin­ anteils derartiger Naturfaserstoffe zum Verfestigen und Versteifen daraus hergestellter textiler Produkte. Es müssen keine zusätzlichen Bindemittel aufgebracht werden. Das Verfahren ist einfach und umweltfreundlich. Es entstehen keine schädlichen Abprodukte. Ein derart verfestigtes Produkt läßt sich leicht durch erneutes Erweichen des Pektinanteils in eine neue Form bringen. Ein Auswaschen der Pektine löst die Bindungen und der Faser­ stoff kann für andere Zwecke genutzt werden. Derartig verfestigte Vlies­ stoffe sind voll recyclingfähig und können problemlos biologisch abgebaut werden.The advantage of the process lies in the use of the natural pectin proportion of such natural fiber materials for strengthening and stiffening therefrom manufactured textile products. No additional binders are required be applied. The process is simple and environmentally friendly. It there are no harmful waste products. Such a solidified product can be easily changed to a new one by softening the pectin Bring shape. Washing out the pectins loosens the bonds and the fibers fabric can be used for other purposes. Fleece solidified in this way fabrics are fully recyclable and can be easily biodegraded become.

Ausführungsbeispiel 1Embodiment 1

Ein tiefziehfähiges Vlies aus ungeröstetem Flachs wird mittels Tiefzieh­ vorrichtung geformt und anschließend in einer Form mit warmen Wasser be­ netzt. Nach etwa 5 Minuten ist die Pektinschicht angelöst und ausreichend erweicht. Unter mäßigem äußeren Druck von 10 kp/cm2 wird der Formkörper bei Temperaturen um 100°C getrocknet und man erhält einen Formkörper, der verfestigt ist und durch seine Steifheit handhabbar wird. Der so herge­ stellte Formkörper aus ungeröstetem Flachs wird danach zur Verstär­ kung von Epoxidharz nach der RTM-Technologie eingesetzt. A deep-drawn nonwoven flax fleece is shaped using a deep-drawing device and then wetted in a mold with warm water. After about 5 minutes, the pectin layer is dissolved and sufficiently softened. Under moderate external pressure of 10 kp / cm 2 , the shaped body is dried at temperatures around 100 ° C. and a shaped body is obtained which is solidified and can be handled due to its rigidity. The molded body made from unroasted flax is then used to reinforce epoxy resin using RTM technology.

Ausführungsbeispiel 2Embodiment 2

Ein vernadeltes Vlies aus geröstetem Flachs wird auf eine durchlässige Siebbahn aufgelegt und durchläuft ein Behandlungsfeld, wo heißer Wasser­ dampf um 110°C durch das Vlies gepreßt wird. Es kommt zum Erweichen der Pektinschicht. Ein anschließendes Kalandern der Vliesbahn mit einer Prägewalze führt zur Ausbildung einer wabenartigen dreidimensionalen Struktur des Vlieses. Bei der anschließenden Trocknung in einem Tunnelofen wird das Wasser entfernt und das Vlies erhält seine feste, verdichtete, dreidimensionale Form. Ein derartiges Vlies läßt sich gut handhaben und in Formen zur Herstellung von Verbundwerkstoffen einlegen. Die ausgebildete dreidimensionale, versteifte Struktur wirkt gegen Delaminierungserschei­ nungen in Verbundwerkstoffen.A needled fleece made of roasted flax is placed on a permeable one Sieve track laid on and goes through a treatment area where hot water steam is pressed through the fleece at 110 ° C. There is a softening of the Pectin. A subsequent calendering of the nonwoven web with a Embossing roller leads to the formation of a honeycomb-like three-dimensional Structure of the fleece. During the subsequent drying in a tunnel oven the water is removed and the fleece receives its solid, compacted three-dimensional shape. Such a fleece is easy to handle and in Insert molds for the production of composite materials. The trained one three-dimensional, stiffened structure acts against signs of delamination in composite materials.
