Abstract

An elastomeric multifilament yarn whose fibrils are not bonded together is made into an elastic bulk yarn with a degree of crimping of at least 40 % and a crimp resistance of at least 50 % by friction texturing. The bulk yarn so obtained is particularly suited to the manufacture of stockings, as well as woven goods, other hosiery and knitted goods, sportswear and outerwear.

Description

Verfahren zur Herstellung eines elastischen Bauschgarnes Process for the production of an elastic bulk yarn
Die Erfindung betrifft ein Verfahren zur Herstellung eines elastischen Bauschgarnes aus einem elastomeren MuItifilamentfaden sowie das nach dem Verfahren hergestellte Bauschgarn.The invention relates to a method for producing an elastic bulk yarn from an elastomeric multifilament thread and to the bulk yarn produced by the method.
Hochelastische Fasern, sogenannte Elastomerfasern sowohl aus Kautschuk als auch aus thermoplastischen Kunststoffen sind bekannt. So besitzen die Elasthanfasern, welche zu den Elastomerfasern gehören, wenn sie aus miteinander verklebten MuItifilamenten bestehen, mangelhafte textile Eigenschaften.Highly elastic fibers, so-called elastomer fibers made of both rubber and thermoplastic materials, are known. The elastane fibers, which belong to the elastomer fibers, if they consist of mutually bonded multifilaments, have poor textile properties.
Für die Verarbeitung solcher Elastomerfasern sind besondere Hassnahmen erforderlich. In der Regel werden die Fa- sern vor der Verarbeitung einem Umwindungs- oder Zwirnverfahren unterworfen. Elastomere der Art sind nicht allein verwendbar, da im textilen Flächengebilde ein spekkiges Aussehen auftritt. Deshalb werden Elastomerfäden immer in Gemeinschaft mit anderen Chemiefasern wie Nylon oder Polyester zu einem zusammengesetzten Garn verarbeitet (DE-A-24 12 592). Dies macht die Verarbeitung in vielen Verfahrensschritten aufwendig und wenig wirtschaftlich. Versuche zur Texturierung mittels einer Mi tnehmerspindel sind bisher daran gescheitert, dass sich die Fäden an die Belastbarkeitsgrenze verdehnen und sich nicht über einen Drallstift ziehen lassen. Auch Texturierversuche bei Elastomeren mittels Friktionsaggregaten führten bis anhin zu keinem Texturgarn.Special hatred is required to process such elastomer fibers. As a rule, the fibers are subjected to a winding or twisting process before processing. Elastomers of this type cannot be used alone, since a spotty appearance occurs in the textile fabric. That is why elastomer threads are always processed together with other chemical fibers such as nylon or polyester to form a composite yarn (DE-A-24 12 592). This makes processing in many process steps complex and not very economical. Attempts at texturing using a slave spindle have so far failed because the threads stretch to the limit of their capacity and cannot be pulled over a twist pin. Texturing tests on elastomers using friction units have so far not resulted in any textured yarn.
Aufgabe der Erfindung ist es, ein einfaches Verfahren zurThe object of the invention is to provide a simple method for
Verfügung zu stellen, welches einem unverklebten Multifi-lament-Elastomerfaden textile und hochelastische Eigenschaften verleiht.To provide, which gives a non-glued multi-lament elastomer thread textile and highly elastic properties.
Die Aufgabe wird erfindungsgemäss dadurch gelöst, dass der elastomere MuItifilamentfaden texturiert wird.According to the invention, the object is achieved in that the elastomeric multifilament thread is textured.
Es ist erstmals gelungen, einen elastomeren Multifilamentfaden zu texturieren. Die texturierten Elastomerfäden weisen eine höhere Dehnung und eine kaum veränderte Festigkeit auf, auch ist der Dehnungsverlauf flacher und regeImässiger als derjenige des glatten Elastomerfadens. Der textile Charakter des erzeugten hochelastischen Bauschgarnes hat den Vorteil, dass eine direkte Verarbeitung zu einem textilen Flächengebilde erfolgen kann.For the first time, an elastomeric multifilament thread has been successfully textured. The textured elastomer threads have a higher elongation and hardly any change in strength, and the stretching process is flatter and more regular than that of the smooth elastomer thread. The textile character of the highly elastic bulk yarn produced has the advantage that it can be directly processed into a textile fabric.
Es ist zweckmässig den Multifilamentfaden mit einer Geschwindigkeit von wenigstens 200 m/min aufzuzwirnen und den rückgestauten, bei 140 bis 190ºC, vorzugsweise bei 160 bis 190ºC thermofixierten Zwirn bei einer Spannung vor dem Texturieraggregat von 0,5 bis 3,0 cN/tex, vorzugsweise 1,0 bis 2,0 cN/tex mittels eines Friktionsscheibenaggregates zu texturieren. Die Friktionstextu- rierung wird bevorzugt mit einem Positorq ® -Aggregat, bei welchem der Faden positiv geliefert wird und damit weniger Spannung nach dem Aggregat aufweist, durchgeführt. Das erhaltene multifile Bauschgarn zeichnet sich durch eine hohe Elastizität und unverklebte homogene Fibrillen aus.It is expedient to twist the multifilament thread at a speed of at least 200 m / min and preferably to the backed-up twine, heat-set at 140 to 190 ° C, preferably at 160 to 190 ° C, at a tension in front of the texturing unit of 0.5 to 3.0 cN / tex Texture 1.0 to 2.0 cN / tex using a friction disc unit. The friction texturing is preferably carried out with a Positorq ® unit, in which the thread is delivered positively and thus has less tension after the unit. The multifilament bulk yarn obtained is characterized by high elasticity and unglued, homogeneous fibrils.
Als Ausgangsmaterial zur Texturierung haben sich besonders die B lockcopolymeren Polyetherester, Polyesterester, Polyetheresteramide, Polyetheramide als geeignet erwiesen. Als weiche Segmente eignen sich die Polyalkylenoxide oder aliphatisehen Polyester hergestellt aus Dicarbonsäuren oder deren Alkylester und Diolen, Dimerfettsäureester etc. sowie Polycaprolactone und als harte Segmente Polyalkylenterephthalate wie Polyethylen- und Polybutylenterephthalat, welche zusätzlich mit Comonomeren wie Isophthalsäure modifiziert sein können, oder Polyamide. Der Schmelzpunkt des erfindungsgemässen Bauschgarnes beträgt wenigstens 200°C. Die Glattgarne werden durch Schmelzspinnen dieser Polymere in einem Spinnstreckverfahren erzeugt. Sie zeichnen sich durch einen bedeutend höheren Anfangsmodul von 80 bis 150 cN/tex als die bekannten Elasthanfasern und durch eine bleibende Dehnung von bevorzugt 10 bis 15 %, höchstens 25 %, bezogen auf die Länge des ungedehnten Garnes aus.The block copolymer polyether esters, polyester esters, polyether ester amides and polyether amides have proven to be particularly suitable as the starting material for texturing. Suitable as soft segments are the polyalkylene oxides or aliphatic polyesters prepared from dicarboxylic acids or their alkyl esters and diols, dimer fatty acid esters etc., and polycaprolactones, and as hard segments polyalkylene terephthalates such as polyethylene and polybutylene terephthalate, which can additionally be modified with comonomers such as isophthalic acid, or polyamides. The melting point of the bulk yarn according to the invention is at least 200 ° C. The plain yarns are produced by melt spinning these polymers in a spin draw process. They are characterized by a significantly higher initial modulus of 80 to 150 cN / tex than the known elastane fibers and by a permanent elongation of preferably 10 to 15%, at most 25%, based on the length of the unstretched yarn.
Das erhaltene Bauschgarn zeichnet sich durch einen Kräuselgrad von mindestens 40 % und eine Kräuselbeständigkeit von grösser als 50 V. aus.The bulk yarn obtained is characterized by a degree of crimp of at least 40% and a crimp resistance of greater than 50 V.
Die Erfindung soll anhand einer Zeichnung näher erläutert werden.The invention will be explained in more detail with reference to a drawing.
