Definitions
- the invention relates to the technical field of textile yarns for technical use for conferring on the products in which they are incorporated, in whole or in part, specific mechanical characteristics such as, for example, anti-cut characteristics and characteristics. of fire.
- the invention also relates to an application of this type of technical thread in the field of protective gloves in particular, and protection in general, both in terms of clothing and certain products in the field of building and public works, and upholstery in the transport field (seats, walls, etc.)
- US Pat. No. 4,299,884 proposes to arrange, parallel to a main core, a plurality of wires whose melting point is less than that of the core and the cover wire, in order to ensure a connection between the main core and the core. cover wire during appropriate heat treatment.
- This document also proposes to use a hot-melt yarn first wrapping, always aiming to bind the core with the cover yarn in second wrapping. There is therefore a connection between the main core and the cover wire.
- the object of the invention is to remedy these disadvantages in a simple, safe, effective and rational manner.
- the problem to be solved by the invention is to be able to isolate the core son in order to create a waterproof wall with the environment, without requiring the use of an intermediate underlayer with the disadvantages listed above, while aiming to achieve the finest possible technical threads, especially in the case of application to cut-resistant protective gloves that comply with EN 388 and ISO 13997.
- a method of manufacturing a textile yarn for technical use comprising a core yarn guiped with at least one hot-melt thread constituting joined turns.
- said hot-melt yarn is subjected to a treatment capable of binding the turns to one another without the said coils adhering to the core yarn.
- the method according to the invention implements a heat treatment in which it is heated continuously, by contact and convection, at high temperature, the outside of the hot-melt wire to create a thermal shock so that only the outside of the envelope of the hot-melt wire receives the energy necessary to bind together the turns, by fusion.
- the invention also relates to a wire for technical use comprising a cored core wire with at least one hot-melt wire constituting contiguous turns, according to which, in the case of an anti-cut wire: the core wire is constituted by the combination of a glass wire and a stainless steel wire; the hot-melt yarn is a polypropylene yarn.
- the glass wire is about 11 TEX and the stainless steel wire about 50 ⁇ ; the polypropylene yarn is about 11 TEX; the twist of wrapping is about 900 t / m;
- the final title is about 40 TEX; the core wire represents about 69% of the composition and the hot-melt wire, about 31%.
- the core wire is constituted by a glass or basalt wire;
- the hot-melt yarn is a polyester yarn additive with a flame retardant product.
- the glass wire is about 34 TEX;
- the polyester yarn is about 17 TEX;
- the final title is about 53 TEX; the core wire represents about 65% of the composition and the hot-melt wire, about 35%.
- the invention finds an advantageous application, which however can not be considered as limiting, for the production of protective gloves.
- the invention can be applied in the field of construction, miscellaneous clothing, seats, and various clothing in the field of transportation.
- the invention is illustrated, by way of non-limiting example, by the single figure of the drawing which shows an embodiment of a textile yarn for technical use obtained according to the invention, this view being shown in section, of a schematic nature and on a large scale, for a better understanding.
- the wire for technical use comprises a core wire (1) covered with at least one hot-melt wire (2) constituting contiguous turns (2a).
- thermofusible wire (2) (cover wire) is subjected to a heat treatment capable of binding the turns (2a) to each other without the said turns (2a) adhering to the wire. of soul (1).
- the level of torsion is calculated so that the turns are joined.
- the wire (2) is subjected to a continuous heat treatment so that the turns (2a) are welded together without adhering to the components of the core wire (1), in order to leave these components a certain degree of freedom for a total flexibility of the final thread.
- the heat treatment consists in heating by contact and convection, continuously and at high temperature, the outside only of the wire (2), so as to create a thermal shock.
- the outside of the thermofusible sheath (2) receives the heat energy necessary for the fusion of the turns (2a).
- core son (1) and hot melt (2) depends on the end use of the wire.
- Composition 31.1% sheath / 68.9% core.
- the yarn for technical use as described and obtained according to the method at the base of the invention constitutes a basic yarn.
- this base wire can receive, during a subsequent operation that can be deferred or continuous to the basic process, another cover resulting, for example, wrapping operations, wiring, torsion, ...
- This cover may have the purpose, separately or in combination: to increase certain properties, such as resistance to cutting, abrasion, tearing, ... to improve certain qualities of perception, such as touch, elasticity, dexterity, especially by adding elastane, for example; improve the implementation of finished products (for example, in the case of elastic seat covers); to be able to perform a dyeing on wire.
- anti-cut and / or fire protection glove suitable for pilots, firemen, ...., for military use, ... clothing for protection against fire and / or cut-off, protective elements in the field of building and public works (blinds, reinforcement of structures, protection of metal beams against fire, filters, ...); trim elements in the field of transport (seats, walls, etc.)
