Abstract

The invention relates to the dyeing and simultaneous finishing of sewing threads which are particularly made of the polyester. The invention is based on the development and application of a lubricant together with a dyeing equalizer agent so that an excellent distribution of both components is achieved and perfectly equal bobbins are obtained. The lubricating agent comprises a silicone oil with derivatives of C10 to C15 fatty acids, oxyethylenated agents, together with 0 to 5 % of an antistatic agent. The equalizer agent is comprised of a equalizer/dispersing agent based on a linear polycondensate in aqueous solution, of a special polyester derivative. The use of this combination provides improved finishing and dyeing compared to conventional processes, particularly improvments related to savings of time and water and the use of practically all the lubricating agent.

Description

Procedimiento para la tintura y acabado simultáneo de hilos de coser. Procedure for dyeing and simultaneous finishing of sewing threads.

Este invento se refiere a un procedimiento para la tintura y acabado simultáneo de hilos de coser principalmente de poliéster.This invention relates to a process for the simultaneous dyeing and finishing of mainly polyester sewing threads.

En el invento se desarrolla un sistema para el acabado de hilos de coser de poliéster, junto con la tintura, con el consiguiente ahorro de energía y tiempo con respecto a los métodos convencionales. Asimismo, este sistema permite que no haya reducción del colorante, manteniendo el rendimiento tintóreo.In the invention a system is developed for finishing polyester sewing threads, together with dyeing, with the consequent saving of energy and time with respect to conventional methods. Also, this system allows no dye reduction, while maintaining the dyeing performance.

El invento se basa en el desarrollo y aplicación de un agente lubricante junto con un agente igualador de tintura cuya conjunción permite lograr una inmejorable distribución del producto y del colorante, conduciendo a bobinas perfectamente igualadas.The invention is based on the development and application of a lubricating agent together with a dye equalizing agent whose conjunction allows to achieve an unbeatable distribution of the product and the dye, leading to perfectly matched coils.

En el estado actual de la técnica, el acabado de hilos de coser de poliéster se acostumbra a realizar mediante dos procedimientos.In the current state of the art, the finishing of polyester sewing threads is usually done by two procedures.

Uno es de tratamiento en continuo, en un medio acuoso o en un disolvente.One is continuous treatment, in an aqueous medium or in a solvent.

Otro método es, por agotamiento posterior a tintura. En ambos procesos se utilizan generalmente, dispersiones de polidimetilsiloxanos junto con parafinas y agentes antiestáticos (medio acuoso) , o bien la misma mezcla en medio disolvente o aceites de parafina especialmente formulados .Another method is, after exhaustion after dyeing. In both processes, dispersions of polydimethylsiloxanes are generally used together with paraffins and antistatic agents (aqueous medium), or the same mixture in solvent medium or specially formulated paraffin oils.

Como se indicó al principio de esta memoria, el procedimiento que se describe y del que se solicita protección, se refiere a un sistema de tintura y acabado simultáneo de hilo de coser principalmente de poliéster.As indicated at the beginning of this report, the procedure described and for which protection is requested refers to a system of simultaneous dyeing and finishing of mainly polyester sewing thread.

Extensos estudios del proceso y las consiguientes pruebas efectuadas han permitido descubrir la combinación de una emulsión de polisiloxano con agotamiento controlado y sin efectos de aglomeración del colorante, con un agente igualador de tintura con efecto de protección del colorante, lo cual permite una tintura y acabado perfectamente igualado.Extensive studies of the process and the consequent tests carried out have made it possible to discover the combination of a polysiloxane emulsion with controlled depletion and without agglomeration effects of the dye, with a dye equalizing agent with dye protection effect which allows a perfectly matched dye and finish.

La emulsión de polisiloxano consiste en un aceite de silicona, de viscosidad comprendida entre 300 cPs y 100.000 cPs, de preferencia entre 5.000 y 15.000 cPs, con unos derivados de ácido graso de cadena entre C10 y C15, oxietilenados , junto con un 0-5% de un antiestático especial .The polysiloxane emulsion consists of a silicone oil, of viscosity between 300 cPs and 100,000 cPs, preferably between 5,000 and 15,000 cPs, with chain fatty acid derivatives between C 10 and C 15 , oxyethylenates, together with a 0 -5% of a special antistatic.

El agente igualador es un agente igualador/dis- persante a base de policondensado lineal en solución acuosa, de un derivado especial de poliéster.The equalizing agent is an equalizing / dispersing agent based on linear polycondensate in aqueous solution, of a special polyester derivative.

La combinación de ambos productos, así como la selección del procedimiento, permite llevar a cabo la tintura y acabado simultáneo de, principalmente, hilos de coser de poliéster.The combination of both products, as well as the selection of the procedure, allows the simultaneous dyeing and finishing of, mainly, polyester sewing threads.

El proceso descrito como nueva invención presenta importantes mejoras sobre los procesos convencionales. Cabe citar algunas de ellas, sin que su descripción represente una limitación al contenido del presente invento. En primer lugar, al no efectuarse en dos baños el proceso de tintura y posterior acabado, se ahorra tiempo y, actualmente mucho más importante, agua y energía.The process described as a new invention presents significant improvements over conventional processes. Some of them may be mentioned, without their description representing a limitation to the content of the present invention. In the first place, since the dyeing process and subsequent finishing are not carried out in two bathrooms, time and, much more importantly, water and energy are saved.

Por otra parte, el proceso descrito en el presente invento conduce a un agotamiento prácticamente total del agente lubricante, lo que equivale a una menor contaminación.On the other hand, the process described in the present invention leads to a practically total depletion of the lubricating agent, which is equivalent to less pollution.

También hay que tener en cuenta que el proceso descrito es resistente al lavado reductor, necesario en los colores medios y oscuros en el caso de poliéster. Esta permanencia también se manifiesta en la posibilidad de matizado y/o retintura, sin necesidad de eliminar el acabado para posteriormente volver a efectuarlo.It must also be taken into account that the process described is resistant to reducing washing, necessary in medium and dark colors in the case of polyester. This permanence is also manifested in the possibility of tinting and / or retinure, without the need to remove the finish and then redo it.

Al ser los productos utilizados no iónicos y aniónicos, presentan una excelente compatibilidad con los colorantes plastosolubles normalmente utilizados en la tintura de fibra de poliéster. El agotamiento se consigue por el proceso y composición de los productos, especialmente diseñados, consiguiendo un reparto excelente entre interior y exterior.Being the non-ionic and anionic products used, they have excellent compatibility with the plastosoluble dyes normally used in dyeing polyester fiber. Exhaustion is achieved by the process and composition of products, especially designed, getting an excellent distribution between interior and exterior.

El hecho de emplear este agente igualador/dispersante a base de policondensado lineal en solución acuosa, junto con el agente lubricante especialmente diseñado, conlleva el que no haya reducción del colorante, con lo que se obtiene un excelente rendimiento tintóreo.The fact of using this equalizing / dispersing agent based on linear polycondensate in aqueous solution, together with the specially designed lubricating agent, implies that there is no reduction of the dye, which results in excellent dyeing performance.

En el estado actual de la técnica, los productos existentes y adecuados para la lubricación post-tintura, conducen bien a la aglomeración del colorante, bien a reducción del mismo, con pérdidas del rendimiento tintóreo del 20-30%, ó bien a filtrajes importantes, sea en la parte de tintura, sea en la parte de lubricación.In the current state of the art, the existing and suitable products for post-dye lubrication, lead either to the agglomeration of the dye, or to reduction thereof, with losses of the dyeing yield of 20-30%, or to important filtrations , either in the dyeing part, or in the lubrication part.

Con el procedimiento ahora descrito, se consigue una tintura y un acabado perfectamente regulares en todos los casos de tintura.With the procedure now described, a perfectly regular dye and finish is achieved in all dye cases.

Para una más clara exposición del proceso se describe un ejemplo de realización, sin que represente ningún aspecto limitativo sobre otras posibles aplicaciones.For a clearer exposition of the process, an embodiment example is described, without representing any limiting aspect on other possible applications.
