Abstract

A coated textile cover sheet is provided with improved tensile strength and tear resistance by the insertion in the base or carrier fabric of yarns having greater tensile strength and lower elongation than the threads of the carrier fabric, either in addition to or in place of corresponding threads of the carrier fabric. The yarns of higher strength may run in the warp and/or weft directions and may be inserted singly or in groups. Yarns of polyamides or of steel may be used.

Description

SPECIFICATION Coated Textile Cover Sheet This invention relates to coated textile cover sheets. The expression "coated textile cover sheet" is generally used at the present time to designate a synthetic product consisting of a carrier or base fabric with a relatively loose weave, for example 6x6 or 8x8 threads per centimetre, which has been made watertight and airtight by coating. The aim of the open weave is not only to reduce the cost of the carrier fabric and hence of the entire end product, but also to permit very firmly adhering coating, since the coating composition is pressed into the open mesh of the fabric. In the case of coatings on one side only, the coating composition is thereby anchored in the fabric, while in the case of coating on both sides the two coating surfaces are very durably joined together by this impression effect.
Cover sheets of this kind can be produced in various weights for the most diverse uses by use of different yarn densities and differences in the coating. The use of light cover sheets is restricted to articles of a relatively small area, such as lorry tarpaulins, awnings, roofings for sideshow tents, and the like. In the case of articles covering a large area, for example air-supported halls, one attempts to comply with the more stringent requirements in respect of strength and stretching behaviour by increasing the yarn density. An increase of yarn density and also increased coating, however, necessarily result in increased weight, so that a limit is imposed on development in this manner. Heavy sheets are very bulky and therefore undesirably difficult to handle, particularly during their production and subsequent use.It must be borne in mind that these cover sheets constitute at the present time an important component in large-area architectural designs, and that therefore substantially new requirements are imposed in respect of weight and dimensional stability. With the usual synthetic yarns of polyamide or polyester which were used hitherto for such cover sheets, these requirements are not satisfactorily met, because even their stretching behaviour (the elongation at break of the above mentioned fibre materials is roughly between 1 5 and 25%) does not permit precise constructional planning without an uncertainty factor. Even with smaller articles, however, both a saving in weight and ood dimensional stability are important.
The invention seeks to provide a textile cover sheet which, without any particular increase in weight, is strengthened in respect of tensile strength and tear propagation resistance, and which is made airtight and watertight by coating.
According to the invention, yarns having greater tensile strength and lower elongation than the base or carrier fabric are inserted at intervals in the latter, and the said carrier fabric is coated in airtight and watertight fashion, at least on one side, with a coating composition whose processing temperature is below the softening point of the yarns forming the carrier fabric. The reinforcement effect is thus not achieved by increased yarn density, as was the custom hitherto, but on the contrary by means of yarns having greater strength and lower elongation than the threads of the basic fabric. These yarns are inserted at intervals, singly or in groups, either additionally to the warp and/or weft threads forming the carrier fabric or, preferably, in place of corresponding yarns in the carrier fabric.
By this means an undesirable considerable increase in weight is avoided, while at the same time it is ensured that the tensile and elongation stresses will first be taken by the stronger yarns before these forces act on the yarns of the carrier fabric. Furthermore, because of their good physical properties these added yarns prevent tear propagation when local damage occurs. They therefore form very effective barriers to tear propagation.
The invention provides the great advantage that the cover sheet can be accurately adjusted to requirements for use in each particular case.
Overdimensioning in physical respects and excessive cost can thus be avoided and new possibilities are opened up for the use of textile fabrics of this kind. The saving in weight achieved by the invention is also very advantageous in comparison with the increase of yarn thicknesses and yarn weights or the attachment of additional reinforcing strips, which would otherwise be necessary. The inserted reinforcements take up a large proportion of tensile stresses and permit reliable architectonic calculations and planning.
According to the invention it has in addition been found that yarns of metal (steel) fibres or of aromatic polyamides are particularly suitable as reinforcing replacement threads.
Specific embodiments of the invention will now be described by way of example and with reference to the accompanying drawings, in which:- Figure 1 is a much enlarged plan view of a section of a base or carrier fabric for use in a cover sheet according to the invention, Figure 2 is a similar view of another such carrier fabric, and Figure 3 is a similar view of a third form of carrier fabric.
In the carrier fabric illustrated in Figure 1, certain of the individual warp threads T are replaced by corresponding single replacement yarns A, running in the warp direction and having greater tensile strength and lower elongation than the threads T.
Figure 2 similarly shows insertion of a replacement yarn At in the weft direction in place of one of the weft threads T,.
In the carrier fabric illustrated in Figure 3, groups of the warp threads T and of the weft threads T, are replaced by corresponding groups of replacement yarns A in the warp direction and A1 in the weft direction. As shown, each group consists of three parallel yarns or threads. The replacement yarns A and A, again have greater tensile strength and lower elongation than the corresponding warp and weft threads T and Tt.
Thus, for example, the threads T, T, of the carrier fabric may be of conventional synthetic yarn, e.g.
of polyamides or polyesters, while the replacement yarns A, A1 may, for example, be made from one of the aromatic polyamides, polymeta-phenylenediamino-iso-phthalamide (mphenlenediamine) or poly-para-phenylenediamino-terephthalamide (p-phenylenediamine), or from metal yarns (e.g. of steel).
The carrier fabric is coated, on one or both sides, with a coating composition which renders the fabric airtight and watertight. The processing temperature of the coating composition must be below the softening point of the yarns or threads forming the carrier fabric. Suitable coating compositions are, for example, polyvinylchloride or a chloroprene rubber.
It will be understood that the yarn thickness, the structure of the fabric and the arrangement of the replacement yarns or threads can be varied as desired to meet particular requirements.
