Definitions
- 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
- 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.
- 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,
- 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.
- 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.
- composition containing the base or body and koniaku may also contain other elements, (adapted to make the material insoluble, impermeable, or flexible).
- 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
- I ficialproducts obtained by synthesisywho'se' coin positicn is essentially the same; as that yof-natural V m a ugiyen solely by way of. example, as it is imposinert 6f a paste or coating-consisting chiefly of.
- the resulting sheets can then be subjected to any desired treatment, such as v taming, .graining.
- composition which has given yaluable 'results is givenbelow by way of example:
- the invention not pnlylcontemplates the use of natural koniaku, but also ofaall arti sible to specify all the difierentsubstances which .areavailable for use,v butkexperience-has shown that in allcases the. addition of koniaku confers. upon the artificial productsuch qualities (chiefly the strength and flexibilityjithat. it may enter into competition with natural leatherfskins, and similar natural substances, uiny their difierent fields'of use.

- a composition-f matter for use in the manufacture of artificial leather and the like which 1. w v. y contains koniaku, tannin,-and wood pulp.
- This... composition can be mixed with a fibrous base or body jof'any kind, ofthetype above indi catedyor it may serve to coat or impregnate a base or body, or it maybe interposed betweenf base sheets, as already explained. 5; way of qexamplathe weight of the above-mentioned come position may be 6 jtim es the weight of the-base LorbOdy. 7
