Es ist bekannt, wässerige Lösungen von Harnstofformaldehydharzen zum Versteifen und Appretieren von verschiedenen porösen und faserigen Erzeugnissen, u. a. auch von Pappe und Textilstoffen für Fersenstücke und Kappen der Schuhe zu verwenden. Diejenigen Erzeugnisse jedoch, die nur mit Harnstofformaldehydharzen imprägniert wurden, weisen zahlreiche Nachteile auf, besonders eine übermäßige Brüchigkeit, Wasseraufnahmevermögen, eine ungleichmäßige Härtung usw. Aus diesen Gründen wurden verschiedene Füllstoffe, wie Fasern, Leim, Latex, Celluloseester und -äther, Alkydharze, Trockenöle, Glycerin zugesetzt. Diese Zusätze beseitigen zwar einige Nachteile, die meisten von ihnen verursachen jedoch eine zu große Klebrigkeit der Halbfabrikate, was verschiedene Schwierigkeiten beim Transportieren, Lagern und bei der Verarbeitung, besonders bei feuchtem und warmen Wetter zur Folge hat.It is known to use aqueous solutions of urea-formaldehyde resins for stiffening and finishing various porous and fibrous products, i.a. also to use cardboard and textile materials for heel pieces and toe caps of shoes. However, those products which have only been impregnated with urea-formaldehyde resins have numerous disadvantages, particularly one Excessive brittleness, water absorption, uneven hardening, etc. Off These reasons were various fillers, such as fibers, glue, latex, and cellulose esters -ether, alkyd resins, drying oils, glycerine added. While these additives eliminate some of the disadvantages however, most of them cause too much stickiness of the semi-finished products, which is various Difficulties in transporting, storing and processing, especially when it is damp and warm weather.

Gemäß der vorliegenden Erfindung werden die angeführten Nachteile dadurch beseitigt, daß ein geeignetes poröses, gegebenenfalls faseriges Material mit einem löslichen, härtbaren Harnstofformaldehyd-, gegebenenfalls Thioharnstofformaldehydkondensationsprodukt unter Zusatz von Polyvinylalkohol oder Polyvinylacetat imprägniert wird. So erhält man Erzeugnisse, deren Eigenschaften beim Lagern, Weichmachen, Einkleben in die Schuhe und auch beim Tragen derselben den Forderungen vollkommen entsprechen. Beim Lagern kleben sie nicht According to the present invention, the disadvantages mentioned are eliminated in that a suitable porous, optionally fibrous material with a soluble, hardenable urea-formaldehyde, optionally thiourea-formaldehyde condensation product with the addition of polyvinyl alcohol or polyvinyl acetate is impregnated. This is how products are obtained whose properties are at Storage, softening, gluing into the shoes and also when wearing them completely meet the requirements. They don't stick when stored

und zeichnen sich durch Elastizität und gleichzeitig durch eine erhöhte Härte aus.and are characterized by elasticity and at the same time by increased hardness.

wurden zu einer Paste zusammengerührt, die auf eine Textilunterlage aufgetragen und ausgetrocknet wurde. Aus Zuschnitten .von so imprägniertem Material wurden Fersenteile und Kappen zur Versteifung von Schuhen hergestellt, die nach Einweichung in einer wässerigen Lösung eines neutralen ao oder auch eines saueren Katalysators der Härtung von Aminoplasten in die Schuhe eingeklebt wurden. Nach Austrocknen und spontaner Härtung waren die Erzeugnisse fest, elastisch, feuchtigkeits- und schweißbeständig.were stirred together to form a paste, which was applied to a textile base and dried out became. Heel parts and caps for stiffening shoes were made from blanks of material impregnated in this way, which after soaking in an aqueous solution of a neutral ao or an acidic catalyst for the hardening of aminoplasts were glued into the shoes. After drying out and spontaneous hardening the products were firm, elastic, moisture and sweat resistant.

werden vermischt und weiter wie im Beispiel 1 verarbeitet. Anstatt des Harnstoffharzes kann auch ein Harz von ähnlichen Eigenschaften angewendet werden, wie zum Beispiel Dicandiamid- und Melaminharz, und zwar allein oder im Gemisch mit Carbamidharzen. Auch einzelne Polyvinylstoffe können untereinander kombiniert werden. Unter dem Begriff Polyvinylacetale sind alle Produkte zu verstehen, die durch Einwirkung von Aldehyden auf Polyvinylalkohol, Polyvinylacetat oder gegebenenfalls einen anderen Vinylester entstehen, also nicht nur ein eigentliches Polyvinylacetat, sondern auch Polyvinylformal, Polyvinylbutyral u. a. sowie gemischte Produkte. Es ist gleichfalls möglich, einen nur teilweise acetalisierten Polyvinylalkohol zu verwenden. are mixed and processed further as in Example 1. Instead of the urea resin, it is also possible to use a resin with similar properties , such as, for example, dicandiamide and melamine resin, either alone or in admixture with carbamide resins. Individual polyvinyl materials can also be combined with one another. The term polyvinyl acetals is to be understood as meaning all products that are formed by the action of aldehydes on polyvinyl alcohol, polyvinyl acetate or possibly another vinyl ester, i.e. not just an actual polyvinyl acetate, but also polyvinyl formal, polyvinyl butyral and other mixed products. It is also possible to use a partially acetalized polyvinyl alcohol.
