Definitions

  • the present invention falls within the technology of technical textiles and pretends to develop a fabric with a multi-axial structure as well as the respective mechanical system that may produce the same.
  • the invention falls within the field of building textile machines, with the intention of supplying the market of technical textiles with a mechanical system capable of performing a mass production of a fabric having a multi-axial structure. Multi-axial fabrics fit into a perspective of the ratio increase between mechanical performance and weight of the material.
  • Technical textiles represent a sector that is strongly developing and which has a market not yet perfectly stabilised. It can be expected that, in a near future, they may advantageously substitute some traditional materials, namely metals in mechanical construction and concrete in civil construction. These products may be used in very different fields as transport industry, civil construction, medicinal applications, protection garments, sports items, military and defence articles, among others.
  • geotextiles are employed to perform separation, reinforcement, filtering, draining and protection functions. They can be textile materials covered with polymers in several uses as in building covers of large dimensions, namely stadiums, airports or sports pavilions.
  • the great advantage of the use of these fabrics in civil construction lays in its low weight, which allows for an increase of bays between supports, making it easier to build and to repair. Besides, architects are allowed more freedom to design shapes and styles.
  • textile materials either in fibres, woven or knitted are used in surgical interventions in implants, filters and blood vessels.
  • the textile structures are identified by its construction, composition, superficial behaviour of the fibres and resistance to decay.
  • the materials used in implants besides having to meet requirements of mechanical order, must likewise be biocompatible so that the human body does not reject them.
  • protective garments they are used to provide a protection against dangerous environments that may cause personal damages.
  • a protection may be mechanical, (bullet- or stabbing-proof garments), chemical, electrical, radiological and bacteriologic.
  • the choice of the material to be used depends on the type and the degree of protection intended for. For instance, the garments used by firemen have to provide for thermal and chemical protection.
  • Thermostable fabrics are chosen therefor, such as aramides or other fibres the finishing of which are flame retarders.
  • the fibres and fabrics of high performance are used, e.g., in sports garments.
  • the last few years we have seen the development of garments with characteristics permitting athletes to increase their performance, namely to increase thermal comfort during sports events.
  • multi-layer structures are used, which allow sweat to migrate towards the outside, the inner layer, which is in direct contact with the skin, being kept dry.
  • composite fabrics, reinforced by textile materials in countless applications in this field, namely in bicycle frames, tennis rackets, skis, surfboards, etc.
  • Multiaxial Fabric Constructions In the market of technical textiles in general and in the field of multi-axial fabrics in particular, there are the materials manufactured by the company Karl Mayer Textilmaschinenfabrik GMBH, called “Multiaxial Fabric Constructions", which result from the stacking of layers of several bi-axial fabrics bound together by a knitted warp. In this kind of fabric, the risk of separation of the several layers that compose the fabric is considerable due to the fact that layers of threads sewn together form its structure.
  • the multi-axial fabric is manufactured in a machine whose basic mechanical principles were acquired from a conventional loom to which are added and adapted the new components with the function of introducing and weaving the diagonal threads of the fabric, in the directions of +45° and -45° with the warp and weft threads.
  • the main advantage the invention wishes to present in relation with the fabric manufactured by Karl Mayer lays in the kind of the resulting structure because, contrary to the Karl Mayer fabric, all the threads are interwoven.
  • Figure 1 shows a schematic view of the fabric with a multi-axial flat textile structure that is the object of the invention
  • Figure 2 shows a perspective view of the mechanical system for the production of the fabric that is the object of the invention
  • FIGS 3 to 7 represent views of parts of the mechanical system represented in Figure 2;
  • FIGs 8 and 9 represent the several phases of the manufacturing process of the fabric that is the object of the invention. Description of an embodiment of the invention
  • the mechanical system developed herein is composed by 3 subgroups that control and co-ordinate the movement of 3 sets of threads in the multi-axial fabric, i.e.: warp, weft and diagonal.
  • Figure 2 represents the most significant aspects of this system, outstanding the set responsible for the guidance and movement of the diagonal threads.
  • weft insertion systems, nor the reed and the feeding systems are fully represented therein.
  • the feeding of the warp threads to the weaving area is made from an organ of conventional warp passing through one or more heddles (11).
  • the insertion of the weft may be performed in two different sheds, one at the front and another at the rear, in relation to the plan of diagonal threads.
  • the weft insertion device (14) shall have two movements: one, in the loom's transverse direction for the proper introduction of the weft thread along the fabric's width and the other, perpendicular to the former direction, to position the weft insertion system in the active shed.
  • Diagonal threads come from bobbins positioned on a stand placed above the weaving area. It has a circular shape and is supported by a central shaft allowing a rotational movement step by step. Each bobbin has a stretching gear to control the tension of the outgoing thread, thus ensuring a better formation of the fabric.
  • the diagonal threads are then passed tlirough a set of thread guides (10) which perform a linear trajectory, in one of the senses of the loom's transversal direction and, thereafter, in the opposite sense. These thread guides (10) are moved by the action of actuators (1) to (8), inside the thread-guide carrier (9).
  • the thread-guides (10) move step by step, linearly and in two opposite senses up to the end of the thread-guide carrier (9).
  • the structure (13) has the function of supporting the thread-guide carrier (9) components, the warp supporting heddle (11), and the drawing rollers (12), in their respective positions during the fabric production.
  • the thread guides displacing the diagonal threads move transversally towards the space freed by the thread guide that has changed path; those of the front line to the right and those of the rear line to the left.
  • the next step consists in the formation of the 2nd shed due to the progress of the heddle amongst the diagonal threads, the same appearing between the diagonals and the warp, which allowed the shed to go from a front position to a rear position in relation to the plan formed by the diagonal threads.

Abstract

La présente invention a trait à un tissu présentant une structure textile plate multiaxiale et un système mécanique pour sa production. La principale caractéristique de ce tissu à structure modifiée et anisotropie contrôlée est l'accroissement de résistance mécanique grâce à l'introduction de fils de renfort dans les directions diagonales à + 45° et - 45° par rapport aux fils de chaîne. Il se caractérise essentiellement par l'entrelacement de trois ensembles de fils : les fils de chaîne (A), les fils de trame (D), les fils en diagonale (B) et (C) étant disposés en deux couches suivant deux orientations : - 45° et + 45° par rapport aux fils de chaîne, lesdites deux couches étant superposées sans entrecroisement. Les fils de chaîne (A) apparaissent de manière alternée dans un plan avant et dans un plan arrière par rapport au plan formé par les fils en diagonale (B) et (C). L'invention a également trait à une machine à tisser pour tissu multiaxial, qui est constituée de sous-ensembles mécaniques afin de réaliser la confection des trois types de fils : un élément d'insertion de fils de chaîne, une lisse porteuse de fils de chaîne, et des guides-fils de fils en diagonale et des cylindres d'étirage.
