Definitions

  • the invention refers to a sewing thread composed of at least two corespun yarns consisting of a lyocell continuous filament core and a cotton fibre wrap.
  • Common sewing threads are generally made of staple fibres or in the form of sheath/core threads, called corespun threads.
  • polyester (PES) and polyamide (PAD) staple fibres have also been frequently applied, mainly due to their essentially higher tenacity, when compared with the relatively low tenacity of cotton sewing threads.
  • PES polyester
  • PAD polyamide
  • Lyocell fibres present a new kind of cellulosic fibres, in their chemical composition similar to viscose fibres, but their production cycle is based on a special organic solvent (NMMO amin oxid) which is recovered within the actual cycle.
  • Lyocell textile linear products can be also manufactured in the form of continuous filaments. The technology of lyocell filament production is described, for example, in US patent No. 6013367 Cellulose multifilament yarn and woven fabrics produced therefrom.
  • Tencel fibres brand name for their textile version
  • the aforementioned sewing threads spun from this blend of cotton and lyocell fibres exhibit the advantage of the possibility of their simultaneous and single phase dyeing with the sewn garment, but their tenacity, dimensional stability and abrasion resistance are still low and therefore such sewing thread is still not suitable enough for sewing heavy garments such as denims.
  • the US patent No. 6136432 Sewing thread, articles sewn therewith, and dyeing of such articles claims a sewing thread consisting of lyocell (staple) fibres and a small proportion (between 5% and 30% in weight) of synthetic fibres (to increase the tenacity and abrasion resistance of this complex thread) which can be dyed together in a simple process, provided that the portion of synthetic fibres is low.
  • the sewing of heavy cotton fabric requires the use of corespun sewing threads, which, like any other sewing threads, are composed of at least 2 individual yams, twisted together in opposite directions, in order to balance the resulting torque.
  • These individual yams in rum consist of continuous filaments, mainly PES filaments located in the central part (core) of the yam, which is wrapped with short fibre (staple) yams.
  • These wrap fibres are prepared by drawing them out of the "rowings" on the drawing frame.
  • the corespun filaments thus ensure the tenacity and dimensional stability of the sewing thread, whereas the wrap fibres protect the synthetic core filaments from overheating caused by friction which is generated in the needle eye when the sewing process runs at high speed.
  • the process for dyeing the PES/PES corespun sewing thread comprises a single phase (not at the same time as the garment, since 100% PES garments are rare).
  • corespun PES/PES threads should be available in many colours and shades, which is costly and which takes time, so that the "just in time” delivery principle cannot be easily applied.
  • 100% PES corespun sewing threads are unpopular in many countries (such as the USA) due to their shiny (synthetic) appearance.
  • the field of applications is similar to the applications of common PES/PES corespun sewing threads or cotton/PES sewing threads: sewing of medium and heavy 100% raw cotton garments, mainly based on denim (jeans) fabrics, velvet fabrics, fustian fabrics, flannel fabrics, cotton jackets, cotton protective clothing, etc., mainly garments which will be sewn with a new thread in raw colour, and the whole garment will then be dyed in a single process.
  • the new sewing thread exhibits the following advantages: 1.
  • the new corespun sewing thread is suitable to satisfy current market demands, i.e. "just in time" delivery of products. Because lyocell, cotton and viscose fibres are of cellulosic origin, they can be dyed either as a thread only, or together with the sewn product, within a single dyeing procedure (preferably by direct dyestuffs), which results in big economic savings. This will reduce the stock of threads, originally dyed in up to 300 colours and shades, thus bringing about big economic effects.
  • the possible use of small proportions of synthetic continuous filaments in the yam core of different dyeability should not cause problems in respect of the colour and shade of the final sewing thread.
  • Tenacity, elasticity and dimensional stability are equal to or better than the parameters characterising PES/cotton corespun sewing threads.
  • a sewing thread highly resistant against increased temperatures caused by friction generated during the sewing process, capable of keeping up with technological developments in modem sewing machines, unlike common cotton/PES corespun sewing threads.
  • the sewing thread of the invention is a sewing thread composed of at least two corespun yams comprising a continuous filament core and a cellulosic fibre wrap, consisting of at least 50% in weight of lyocell filaments, located in the individual yam cores, and at least 15% in weight of the cellulosic fibre wrap, all the proportions being considered in terms of the total thread weight.
  • the cellulosic fibre wrap is made of cotton or viscose using a small proportion of filaments of viscose or other filaments (even synthetic ones) located together with the lyocell filaments in the individual yams cores.
  • FIG. 1 An example of the cross-section of this new corespun thread is shown in Fig. 1 , where the whole sewing thread (1) consists of 3 individual yarns (2), each of which consists of continuous core filaments (3) and a wrap (4). It can be mentioned, as an example of the production technology of this sewing thread, that the core filament has a fineness of 132 dtex, the fibres of the cotton wrap exhibit a fineness of 65 dtex, the twist of the individual yams being 790 v/m and the twist of the total sewing thread being 810 v/m.

Abstract

La présente invention concerne un fil à âme destiné à coudre des tissus et des vêtements, qui est composé d'au moins 50% en poids de filaments continus de fibres lyocell constituant l'âme et d'au moins 15% en poids de fibres cellulosiques coupées (par exemple, du coton ou de la viscose) enroulées autour des filaments de l'âme et constituant par conséquent l'enveloppe extérieure des fils de ce fil à coudre complexe. En raison de sa ténacité augmentée, de sa stabilité dimensionnelle et de son faible frottement superficiel, le fil de l'invention est particulièrement adapté à la couture des tissus de coton moyens et épais, tels que les tissus denim (jeans), les tissus de velours, les tissus de futaine, les tissus de flanelle, les vestes en coton, les vêtements de protection en coton, etc. En outre, le fil à coudre entièrement cellulosique de l'invention offre l'avantage de pouvoir teindre les vêtements de coton cousus bruts (tissu et fils) en une seule et unique opération.
