Abstract
Disclosed is a method for the production of a planar textile structure, especially a woven belt band, especially for safety belts in motor vehicles, consisting of warp threads and at least one weft thread. The method is characterized in that at least one hybrid multifilament thread, made up of at least first and second filaments, is used for weaving, said second filaments having a higher melting point than the first filaments. Flexible elliptical and flat interlacing points are formed during shed closing of the warp threads, and the belt band is thermofixed after weaving, whereby the first filaments melt and the second filaments of the multifilament yarn are at least partially glued together.
Description
METHOD OF PRODUCING A WOVEN BELT BAND
The invention relates to a method of producing a textile sheet fabric, particularly a woven webbing, more particularly a vehicle occupant restraint belt, comprising warp threads and at least one weft thread.
A wide variety of methods of producing such webbing and their attendant disadvantages are known. As a rule, the warp threads thereof consist of multifil yarns whereas for the weft thread(s) multi- or monofil yams are employed singly or in combination. Whilst making a webbing exclusively of multifil yarn for the weft thread material has the disadvantage of it having practically no CD stiffness and elasticity, webbing with weft threads of monofil material although featuring the desired CD and elasticity, suffer the disadvantage that after a certain number of chaffing actions the monofil weft threads at the edges where the weft returns, juts from the belt in forming a hard sawtooth-like woven edge damaging to the clothing of the vehicle occupant or even causing injury to the chest and neck of the occupant. By comparison, webbing made of monofil weft material is thick as compared to webbing made exclusively of multifil material.
According to a broad aspect of the present invention, there is provided a textile sheet fabric comprising warp threads and at least one weft thread, the textile sheet fabric comprising: at least one weft thread is a hybrid multifil yarn composed of at least first and second filaments, the second filaments having a melting point higher than that of the first filaments, the first and second filaments are provided in the keying points with the intersecting warp threads as flexible elliptical low-profile keying points, the yam structure of warp and weft threads is provided in the edge region as low-profile weft reversals, from thermosetting the webbing after weaving, the first filaments melt and the second filaments of the multifil yarn interbond at least in part.
The invention is based on the object of proposing a method for producing a woven webbing which eliminates, or at least greatly reduces, the disadvantages known from prior art.
TDO-RED #8377229 v. 1 This method has the advantage that incorporating the hybrid multifil yarn in the weft now makes it possible to achieve the positive structures of the keying points in the woven.
The hybrid multifil yarn comprises at least first and second filaments. This yarn simply termed õhybrid yarn" hereinafter is wefted in forming flexible elliptical and low profile keying points in shed closure of the warp threads, as is unattainable with monfil yarns. In setting, after weaving, the multifil yarn in accordance with the invention is heated to above the melting point of the low-melting filaments. It is this melting of the low-melting filaments that results in the high-melting filaments of the multifil yarn interbonding at least in part so that the multifil yarn is or can also be bonded as a whole or preferably its outlying filaments in addition to the keying points with the intersecting warp threads in thus achieving the high CD consolidation of the webbing. The process as described for modifying the mechanical properties - in achieving the description CD
stiffness and elasticity - is done with the threads ondulated, i.e. the thickness of the woven webbing is thinner and the webbing surface formed by the warp threads is smoother because the heads of the keying points are configured less prominent.
As already indicated above, producing a webbing in accordance with the invention results in a elliptical low-profile, soft weft reversal in the region of the edges, because of the multifil yarn structure. Now, abrasion of the selvedge no longer results in the feared sawtooth effect and its negative consequences as in prior art from damage to the edges of the webbing.
In one aspect of the method in accordance with the invention polyamide is used for the first filaments and polyester for the second filaments, resulting in an optimum harmonizing pairing of the materials in the webbing.
In another advantageous aspect of the invention polyester is used for both the first and second filaments in the hybrid multithread of the weft thread. This has the additional major advantage of the material permitting better recycling. Advantageously the first filaments in this case are made of a modified polyester.
TDO-RED #8377229 v. 1 Thermally treating the hybrid yarn textile sheet fabric at approximately 220 C
by the method in accordance with the invention results in the individual second filaments interbonding so that in the weft thread a monofil-type yarn body is achieved having the mechanical properties (resiliency, low fluffiness, stiffness) of a monofil yarn in thus combining all positive features of multifil yam and monofil yarn in the method in accordance with the invention and the resulting product.
The method in accordance with the invention is applicable, of course, to all known types of webbing, the achievable advantages of which for the first time now combine low thickness of the webbing, smoother surface thereof, soft reversals in the region of the edges, resiliency, CD
stiffness and perfect surface quality.
Advantageously, multifil yams are employed as the weft thread, the mass ratio of first filaments to second filaments being in the range of approximately 20% - 90% to approximately 10%-80%.
