"rras ric ARTIFICIAL LEATHER 7 i were I v COMPOSITION PauLHenri Perrinyflhatouhand Gaston Hubert Vulliet-Durand, Paris, France; said Vulliet Durand assignor to said Perrin No Drawing, Application March 12, 1931, Serial No. 522,154. In France March 20, 1930 The present-invention relates to artificial products-imitating leather, skins, parchment and like materialgof animal or vegetableorigin, and possessing qualiticswliich are much superior to those of the artificial leathers hitherto produced.
7 The imitation leathers nowsold in the market are manufactured by impregnating textile fab- .rics, or agglomerating leatherpowder, obtained .by grinding waste leather, said products being thereafter varnished and given-a suitable grain.
.The agglomerated leather powder products are those whose qualities come the nearest to natural leathenbuti they offer serious defects, and chiefly the following: a i
- l--Their strength is relatively small, and in particular, they will tear at the'seams;
,2'They are not sufficiently flexible to allow their use in the manufacture of fancy leather 3'-They are of thin sheets.
The present invention has for its object to obviate the defects above specified and to impart to such products the qualities which they lack, and chiefly an unusual strength and a remarkable flexibility, by adding to the raw matenotadapted for the manufacture rial a substance called konniyakuko or konimanufacture of imitation leather in the strict sense of the word, but it covers all artificial products similar to leather, skins, or like material, either by their appearance or by their composition, such products having in all cases the two essential qualities of natural leather, that is a great strength and a good flexibility, and this to a variable degree, which may equal or even exceed that of natural leather or like substances.
The composition of matter to which the koniaim is added may vary considerably, and certain examples will be further given, but whatever be the composition adopted, experience has shown that the koniaku confers upon the result? ing artificial product an extraordinary strength,
so that the seams cannot practically be torn, as well as a flexibility comparable'with that of the skins employed in fancy leather work. Furthermore, the products containing koniaku may be 10 Claims. (Cl. 106--39) manufactured in thin sheets, and may be subjected to the various usual treatments of natural leather, such as tanning, graining, dyeing, colouring, embossing, etc.
The raw material forming the body or the base of the final product may be of any kind, and it powdered material (such as powdered cotton, wood, peat etc): It may be advantageous to use the powder obtained from waste natural leather or other material commonlyemployed in the manufacture of artificial leather.
The base may also consist of a fabric or netting formed of fibres, threads, etc., which are naturally or artificially arranged or interwoven in a more or less regular manner.
Broadly, the nature and texture of the base or body can be varied within wide limits, according to the abundance and the price of the raw material at hand, and to all other conditions, as will be recognized by those skilled in the art.
The composition containing the base or body and koniaku may also contain other elements, (adapted to make the material insoluble, impermeable, or flexible). Among these, tannin may be mentioned as a typical example of a material effective in rendering the material insoluble, and glycerin, starch syrup and other hygroscopic substances as softeners.
' Sheets of artificial leather of suitable thickness may be directly obtained from the aforesaid composition, generally in the form of a paste, by a simple drying. The treatment may also be carried out by calendering, rolling, moulding, spinning, or the like.
Another method consists in coating or impregnating a solid base or body with a composition containing koniaku, either alone or mixed with other substances. This method is chiefly used for the impregnation of textile fabrics, sheets of paper, etc. at atmospheric pressure or under a suitable pressure, or with the alternate application of vacuum and pressure, as is usually em played in impregnation processes.
Sheets of artificial leather can also be produced by superposing sheets of paper (such as unsized paper, tissue paper, etc.) or textile fabric or the like, between which are interposed ,The base or body may further. consist of .a
