TTO'Q/VEY Patented Oct. 25, 1949 COATED ELASTIC FABRIC Carleton S. Francis, Jr., West Harwich, Mass., assiznor, by mesne assignments-to American Viscose Corporation, Wilmington, Del., a corporation of Delaware Application June 22, 1944, Serial No. 541,548
6 Claims.
This invention relates in general to elastic fabrics and in particular to coated elastic fabrics made by the use of thermoplastic transfers.
In the production of coated elastic fabrics for use in girdles, brassires, shoe fabrics, surgical bandages, gas masks and certain industrial uses, it is essential that both the total weight and the thickness of such sheet materials be maintained at an absolute minimum. However, such coated materials must meet the following stringent specificaticns:
(a) The fabric must be extremely light in weight;
(b) The fabric must be waterproof and waterrepellent;
(c) The coating must not become tacky when folded and stored under pressure;
(d) The coating must not become brittle or inflexible at the lowest temperatures experienced in the arctic regions;
e) In many cases, as in gas masks, it is desirable that the coating be impermeable and proof against the effects of both water vapor and gases.
It has been found that elastic fabrics made by conventional methods of coating elastic fabrics will not meet all of the above stringent requirements.
In one prior method an elastic fabric is coated v'ith a solution of a film-forming material in a volatile solvent and the solvent then evaporated to deposit the material on the fabric. However, it invariably results that the rst coating tends to penetrate and impregnate the yarns so that it is necessary with such a prior method to apply a plurality of coatings, as many as six or seven, in order to nally produce a film which is free of pin holds and relatively smooth. Such a method obviously results in the use of a large quantity of the coating material, the larger part of which is useless since it is lost in impregnating the yarns. Thus, when such solutions are applied to elastic fabrics containing covered elastic threads, the impregnation of the yarn results in the bonding of the textile covering to the elastic filament, thereby seriously affecting the natural elasticity of the elastic yarns and stiffening these yarns, and finally the solutions tend to bond the yarns to each other at their points of crossing, thus limiting the elasticity of the fabric as a whole. In another prior method the use of volatile solvents is avoided by preforming a relatively thick film of plastic material and calendering the same onto the surface of the fabric. However, it has been found that it is impossible to produce a lm by calendering which has a thickness less than 0.002". Even if films thinner than 0.002 could be produced by calendering, it would be impractical to apply them to the surface of elastic fabric because such lms are not self-supporting and they could not be run through automatic calenders at a rate which would make the process commercial. When the thicker calendered lms are applied to elastic fabrics, a bulky, thick product always results and it is frequently the case that the lm. by reason of its greater thickness, tends to seriously diminish the elasticity of the fabric. In such cases the advantage of having elastic rubber threads in the fabric is lost.
Accordingly, it is a general object of the present invention to overcome present disadvantages residing in prior coated fabrics while providing coated fabrics with a thin continuous impervious coating.
Another general object of the invention is to provide a light-weight fabric which will have high tear resistance, high tensile strength and a substantial stretch while exhibiting a material recovery after being stretched.
A further specific object is to provide an elastic textile fabric with a thin continuous impervious coating.
Other objects of the invention will in part be obvious and will in part appear hereinafter.
According to the present invention, an elastic textile fabric is coated without impregnating the yarns thereof by applying to one or both sides of the fabric a non-self-supporting continuous film of a thermoplastic elastomer, preferably less than .002" in thickness, supported on a temporary backing to which the lm exhibits no permanent adhesion, applying heat and pressure to the assembled materials to cause the film to adhere to the surface portions only of the yarns and, preferably after cooling the article, separating the temporary backing sheet from the coated fabric.
'Ihe term elastic fabric as used in the speciiication and in the appended claims is intended to include the following: (a) Knitted fabrics, in which the elastic thread, (e. g. a rubber thread) either bare or covered with a textile covering, is actually knitted with elastic or non-elastic knitting yarns. In this case the rubber thread forms the loops in the fabric.
(b) Inlaid knitted fabrics, i. e. knitted fabrics ink which the elastic thread is merely fed in between the non-elastic textile yarns. Thus, in a knitted fabric the elastic yarn would lie straight and run through the loops.
(c) Woven fabrics in which the warp and/or weft yarns are elastic thread, either bare or covered.
The expression open mesh fabric as used in the specification and in the appended claims denotes a fabric having discrete and substantial spaces between the yarns in such a fabric, and may be an elastic fabric as deined above, o r an ordinary fabric without rubber threads and formed by weaving, knitting, netting, crocheting or otherwise.
Some common varieties of open mesh fabrics are, for example, scrim, cheesecloth, bobinet, and crinoline. It 1s to be understood that the fabrics may be formed of natural or articial textile bres and mixtures thereof.
For a more complete understanding of the nature and objects of the present invention. reference should be had to the accompanying drawing in which Fig. 1 is a dlagrammatical representation in side elevation of means for carrying out one embodiment of the process of the invention;`
Fig. 2 is a cross-section of another embodiment of the article comprising one layer of fabric coated on both sides with an elastic lm;
Fig. 3 is a third embodiment of the article in which two layers of elastic fabric are united by means of an enclosed elastic ilm;
Fig. 4 is a cross-sectional view of one embodiment of the fabric of the invention in the unstretched condition; and
Fig. 5 is a cross-section of the fabric illustrated in Fig. 2 after stretching.
According to the present invention, the fabric is combined on one or both sides thereof with a continuous transfer lm comprising, as the essential film-forming agent, a natural or synthetic elastomer. Thus, there'may be used natural rubber or any of the synthetic or artificial rubbers possessing the elastic characteristics of L natural rubber; for example, there may be used in the invention one of the synthetic elastomers given in the table below or any compatible mixture of such elastomers.

Thin lms formed of a synthetic elastemer have the property of stretching and recovering after stretch. In accordance with this inface by spraying,
vention, these properties, inherent in the elastomers per se, are enhanced by the fact that the yarns of the fabric are not impregnated with the i'llm but are bonded thereto only at the peak points of the fabric, which permits the yarns to recover their original shape after stress. Thus the finished product may be subjected tc substantial stress and strain without permanent distortion or without permanent change in dimension, since after the stress is removed the synthetic elastomer film causes the fabric to return to its original structure and shape. thetic elastomers contemplated by the invention are superior to natural rubber in their resistance to oils, greases,v water vapor, and dry cleaning uids.
To facilitate handling the transfer film which is so thin that it is not self-supporting, the nlm may be supported on temporary backing may be any drum, band or sheet material having a. smooth surface to which the transfer lm exhibits no permanent adhesion. When the transfer nlm is an organic hydrophobic material, the backing sheet is formed in whole or is coated with a hydrophilic material, such for example, as regenerated cellulose, an alkali-soluble water-insoluble cellulose ether, gelatine, casein, denitrated nitrocellulose, deacetylated chitin, zein, and the like; or with a thermosetting resin in the infusible state; or with a thermoplastic material which has .a thermal softening point higher than the thermal tacking point of the synthetic elastomer, or a coated backing sheet in which the coating has a thermal softening point lower than the thermal tacking point of the transfer nlm. There may -be used also backing sheets of fibrous material, such as papers, fabrics and felts which. are coated with one of the above-mentioned materials to provide a smooth, non-porous surface to which the transfer lm is applied. The natural or synthetic elastomer film has a thickness of not over .002, preferably between .001" and .002.
The transfer lm may be formed on the temporary backing in any suitable manner, for example, by applying the thermoplastic material as a solution or molten mass to the backing surdipping, calendering, and the like. The invention also contemplates that the transfer lm may be applied to a continuously moving backing surface, such as a drum, band or web, and transferred from such backing sheet at a point spaced from the point of application of the film thereto. The expression temporary backing scription and in the appended claims is intended to include a backing in the form of a sheet, web, or an endless band, or a drum.
In producing the coated elastic fabric, one
bled materials are preferably cooled and the backing sheets stripped ofi.
In one embodiment the elastic fabric is stretched prior to the transfer and the lm is transferred thereto while the fabric is in its stretched condition after which the backing sheet is stripped off and the fabric allowed to relax.
There is shown in Fig. 1 one embodiment o1' Further, the Syna temporary backing. The
as used in the following detailed de' suitable means for carrying out the invention in which two backing sheets I0, each carrying an elastic transfer film II on one surface, are fed between the assembly rolls I3 so as to contact the film with a web I2 of elastic fabric supplied from the roll 9. The assembled sheets are then passed around the heated drum I4, being pressed against the drum by-means of the blanket I5 which travels about the pressure rolls IB and the tension rolls l1. Heat and pressure applied by the drum I4 and blanket I5 cause the transfer film to adhere to the raised surface portions of the yarns without impregnating the yarns. The stripping of the backing sheets from the product is facilitated if the composite sheet material is cooled prior to stripping, for example, by passing the composite sheet material through the cooling chamber I8. The backing sheets are stripped from the coated fabric in passing around the stripping rolls 20. The backing sheet I and the coated fabric I9 are wound up separately.
The product produced is shown in Fig. 2 and comprises a single layer of elastic fabric I2 coated on each side with a thin continuous elastic film I I. It is to be understood, however, that the fabric may be coated on one side only. Alternatively, there is shown in Fig. 3 a further embodiment of the article which comprises two layers of elastic fabric I2 united by and enclosing a single continuous elastic film II. It is clear from these examples that the number and relation of the films and layers of fabric may be varied to produce articles of various types without transcending the scope of the present invention.
For a more detailed explanation of the features and characteristics of the present article reference should be had to the detailed drawings in Figs. 4 and 5. In Fig. 4 there is shown a single layer of elastic fabric in an unstretched condition. It should be noted that both the weft and warp yarns of the fabric comprise an elastic rubber core 2| covered with a spiral textile covering 22. In Fig. 4 the yarns are shown in a relaxed or unstretched condition. The thin continuous elastic lm I I is shown as bonded to the exposed or raised surfaces of the covered yarns and the material of the film does not penetrate the yarn structure to any substantial extent. Accordingly, the yarns of the fabric are not bonded to each other at their points of crossing so the yarns are free to move and slide one upon another to a substantial extent. When the fabric illustrated in Fig. 4 is stretched its structure is represented in Fig. 5. In this figure it will be noted that the yarns as a result of the stretching are slightly smaller in diameter and that the film has been stretched with the yarns, the lm being bonded to the yarns at the raised exposed surfaces 23, but the film is free from attachment to the yarns in the spaces 24 between such points 23. It will thus be noted that the present invention provides a novel method of producing a coated elastic fabric without substantially altering the elastic characteristics of the fabric. The thin elastic film II follows the expansion and contraction of the fabric freely and the yarns of the fabric are not bonded to each other at their points of crossing. It would be impossible to produce an article such as that illustrated in Figs. 4 and 5 by the use of prior methods such as by coating the fabric with a solution of film-forming material in a volatile solvent because the solution would maturate the fabric, impregnate the yarns, and upon evaporation of the solvent the film-forming material would form a coating around each yarn and bond the yarns at their points of crossing. On the other hand, the present invention provides a method of producing an extremely lightweight fabric because the film II, although it is extremely thin and non-self-supporting, is applied to the fabric in such a manner that it is not disrupted or broken by the transfer operation. Because the elastic film is extremely thin, preferably having a thickness less than .002 inch, it is capable of following the expansion and contraction of the fabric without interfering with or substantially modifying the elastic fibres of the fabric, and despite the fact that the film is anchored near to the raised surface of the yarns, it does not become detached when the fabric expands and contracts. When one attempts to calender a thick self-sustaining elastic film to an elastic fabric by prior methods there is always produced a product heavier, less flexible and less elastic than is produced by the present invention.
It is to be understood that many variations and alternatives are possible in the article and process of the invention. If desired, the transfer film which is applied to the one side may be dissimilar in chemical composition, color, thickness and other characteristics from the transfer lm which is applied to the other side. Also, the natural or synthetic elastomer film may be ap, plied to the elastic fabric in an unvulcanized condition and the vulcanization of the film can be effected during or after transfer.
By way of illustration but not by way of limiting the invention, there will be given the following specific examples:
Example I An elastic webbing is made by coating one side of a knitted elastic fabric having elastic threads knitted in and forming the loops with a film of a synthetic elastomer comprising neoprene having a thickness of .002" supported on a smooth v, calendered paper by passing the fabric and the 2 to 4 times greater than the uncoated fabric.
The film follows the expansion and contraction of the fabric without delamination.
Example II A mass of polymerized butadiene (Buna rubber) is dissolved in a suitable solvent and applied to the surface of a sheet of glycerinated regenerated cellulose, after which the solvent is evaporated to leave a continuous extremely thin film of the synthetic elastomer on the cellophane. The coated cellophane and a Woven fabric made of yarns comprising continuous filament elastic Vinyon (vinyl chloride-vinyl acetate copolymer) is passed through an apparatus similar to that shown in Fig. 1 above with the synthetic elastomer lm in contact with the fabric and the layers subjected to suicient heat and pressure to render the synthetic elastomer tacky and cause it to bond to the raised portions 'of the surface of the Vinyon" fabric. In the pre- 7 ferred embodiment the temperature used is such -that the surface of the Vinyon laments is also rendered tacky, thus improving the anchorage between the fabric and the synthetic elastomer lm.
Example III To an elastic fabric containing rubber threads of the type disclosed in U. S. Patent No. 2.152.826, there is applied on one side a lm having a thickness of 0.002" of polyvinyl butyral resin. IThe lm is first formed on a sheet of cellophane as a temporary backing, and is then applied to the fabric at a temperature of 150 C. and 200 lbs. pressure to cause the film to adhere to the peaks of the fabric. There is thus produced a composite material in which the lm, while continuous over the yarns, does not penetrate the spaces between the yarns. The strength of the bond between the fabric and the film, as well as the elasticity of the composite material, are particularly noticeable at low temperatures.
The coated elastic fabric of the present invention is applicable for a wide variety of uses where both water-repellency and elasticity are desirable, interalia, as waterproof coverings such, for
example, as shoe and overshoe material, baby panties, hospital sheeting, mattress covers, surgical gloves, waterproof beach bags, life vests, girdles and the like. Also for bathing caps. raincaps, glider covers, outdoor furniture covers and other articles requiring stretch and resistance to water. impermeability of the coated fabrics, they are particularly designed for balloon fabrics, parachute cloth, air and gas ducts, and the like.
Since certain changes in carrying out the above y process, and certain modifications in the article which embody the invention may be made withot departing from its scope, it is intended that all matter contained in the above description shall be interpreted as illustrative and not in a limiting sense.
