Description
Die Erfindung bezieht sich auf einen Faden aus Coregarn, bestehend aus zwei oder mehreren Corefäden, von denen jeder aus einem Seelenfaden aus endlosem, synthetischem Material besteht, der im Spinnverfahren mit Fasern oder Fadenteilen pflanzlicher, halb- oder vollsynthetischer Herkunft unter gleichzeitiger Drehungsgebung so ummantelt wird, daß der Seelenfaden vollkommen abgedeckt ist, und wobei die Corefäden mit der Spinndrehung zahlenmäßig etwa gleicher aber im Drehsinn entgegengesetzter Zwirndrehung zusammen verzwirnt werden.The invention relates to a thread made of core yarn, consisting of two or more core threads, each of which consists of a soul thread made of endless, synthetic material that is im Spinning process with fibers or thread parts of vegetable, semi-synthetic or fully synthetic origin simultaneous rotation is sheathed so that the soul thread is completely covered, and where the core threads with the spinning twist are roughly the same in number but opposite twisting in the direction of twist be twisted together.
Ein solcher Faden ist aus der DE-AS 11 55 040
bekannt Da nach diesem Stand der Technik die Fertigung des Coregarnes in der Weise erfolgt, daß
Spinndrehung und nachfolgende Zwirndrehung sich in der Drehrichtung entgegenstehen, wird ein letztlich
offener oder nahezu offener, also drehungsloser Fadenverband erhalten. Besondere Vorteile weist ein
solcher Faden bei der Verarbeitung zu textlien Flächengebilden auf. Für die Verwendung als Nähfaden,
insbesondere für schnelle Nähvorgänge mit hohen Fadenbelastungen und mit erhöhter Nadelerwärmung
ist dieser bekannte Faden jedoch aufgrund seine« nahezu offenen Fadenverbands nicht geeignet
Aufgabe der Erfindung ist es, einen Faden dei beschriebenen Art so weiter zu entwickeln, daß er al;
Nähfaden verwendbar ist, der auch der erhöhter Fadenbelastung bei schnellen Nähvorgängen standhäl
und gleichzeitig der dabei auftretenden Nadelerwär mung entgegenwirktSuch a thread is known from DE-AS 11 55 040. Since, according to this prior art, the core yarn is manufactured in such a way that the spin twist and the subsequent twist twist oppose each other in the direction of rotation, an ultimately open or almost open, i.e. non-twisting thread association obtain. Such a thread has particular advantages when it is processed into flat textile structures. For use as a sewing thread, in particular for fast sewing processes with high thread loads and with increased needle heating, this known thread is not suitable because of its "almost open thread association"
The object of the invention is to further develop a thread of the type described so that it al; Sewing thread can be used, which also withstands the increased thread load during fast sewing processes and at the same time counteracts the needle warming that occurs in the process
ίο Diese Aufgabe wird bei einem gattungsgemäßer Faden dadurch gelöst daß der Faden ein Nähfaden ist dessen Seelenfäden aus ausverstrecktem und fixierten: Material bestehen, und daß die Spinndrehang und die Zwirndrehung je etwa 1000 Drehungen/m betragen.ίο This task is in a generic Thread loosened by the fact that the thread is a sewing thread whose core threads are made of stretched and fixed: Material exist, and that the spin twist and the twist twist are each about 1000 turns / m.
Bei diesem Faden wird bei der Zwirndrehung eine optimale Haftverbindung zwischen Seelenmaterial um Umspinnmaterial, und damit eine hohe Fadenfestigkei gesichert, da im Gegensatz zum Stand der Technik gemäß der DE-AS 11 55 040 eine Rückdrehung de Spinndrehung beim Zwirnvorgang aufgrund der hohei Drehungszahl verhindert wird. Damit wird auch eim relativ rauhe Fadenoberfläche erhalten, die wahrem eines schnell ablaufenden Nähprozesses mehr Luft mi sich reißt und damit einer überhöhten Nadelerwärmunj entgegenwirkt Ferner wird durch die beanspruchter Mermkale eine weitgehende Kringelfreiheit des Faden! sichergestellt.With this thread, an optimal adhesive connection between the core material is created during the twisting Wrapping material, and thus a high thread strength secured, as in contrast to the prior art according to DE-AS 11 55 040 a reverse rotation de spin rotation during the twisting process due to the high i Rotation speed is prevented. This also gives a relatively rough thread surface, the true one a fast sewing process more air with tears and thus an excessive needle heating counteracts Furthermore, the claimed features mean that the thread is largely free of curls! ensured.
Die Erfindung wird im nachfolgenden Ausführungs •beispiel näher erläutert:The invention is explained in more detail in the following embodiment • example:
Ein Coregarn, gebildet aus einem verstreckten weitgehend ausfixierten sogenannten Seelenfaden au Polyester dtex 74, wird mit 1050 Drehungen 5 mi langstapeliger Baumwolle umsponnen, und zwar so, da( der Seelenfaden vollkommen abgedeckt ist. Der Antei Umspinnungsmaterial zum Seelenfaden beträgt in etwi 65% Seelenfaden und 35% Umspinnungsmaterial un< die Endnummer dtex !25. Zwei solche Coregarn werden nach an sich bekannter Reinigung oder un< Fachung mit 1080 Z-Drehungen im Naßzwirnverfahrei zusammengezwirnt. Zu Färbepaketen umgespult wer den diese gefärbt, getrocknet und zu Verkaufsspulei aufgewunden. Dabei wird die Fadenoberfläche mit eine gleitenden Avivage versehen.A core yarn, formed from a stretched, largely fixed, so-called core thread au Polyester dtex 74, is spun with 1050 turns 5 mi long staple cotton, in such a way that ( the thread of the soul is completely covered. The proportion of wrapping material to the soul thread is about 65% core thread and 35% covering material and the end number dtex! 25. Two such core yarn are after cleaning known per se or un <piling with 1080 Z twists in the wet twisting process twisted together. They are rewound into dye packs, who dye them, dry them and turn them into sales reels wound up. The thread surface is provided with a sliding finish.
