This invention relates to improvements in fabrics and methods of making fabrics and more particularly to a fabric having one face finished with a surface of short fibres, to give 'g a surface similar to that of a pile or nap fabric or of other fabric finishes or serving to anchor to the base, an artificial leather or other coating.

Fabrics of the type outlined above have heretofore required a heavy base from which a nap may be raised Without unduly weakening the fabric or has necessitated the weaving into the fabric of loops of thread which may then be cnt to form a pile fabric. The roduction of a surface of this type has there ore been limited to fabrics in which the surface fibres have been secured to the base of the fabric as a part of the threads Woven into or forming the fabric base. This has necessitated an expensive type of Weaving and has limited the formation of surfaces of this type to expensive fabrics.

An object of my present invention is to provide a fabric having a surface similar to pile or nap fabrics or to similar finishes but in which the pile or surface fibres are secured to the base fabric without being Woven therein.

Another object of the invention is to provide a fabric having a fibrous surface of the characterindicated which may be mounted and secured on a fabric base independently of the character or type of the fabric base and for which a coarse, loosely Woven, fabric base may be used.

Another object of the invention is to provide a method by which a surface of fibres suitable for pile or other finish may be formed and secured in a fabric.

A further object of the invention is to form or secure to a fabric base a surface of fibres secured in said fabric as a base and by means of said surface. fibres to anchor to said base a continuons coating of the character used in making artificial leather o r arwater proofed siii-face. f

Still further objects of the invention are to h provide a fabric having the appearance and characteristics of a pile fabric and being, at the same time, water proof, and suitable for use as a lining for automobile tops and closed vehicles, to provide a cheap and inexpensive method for making pile fabrics, and to provide a method for anchoring loose fibres so firmly to a fabric base that they may be subjected to napping, combing, shearing or, indeed, any similar finishing operation.

iVith these and other objects in view, which will be apparent from the following detailed description, the invention comprises the methods and products described and set forth in the following specification and claims.

The various features of the invention are illustrated in connection with the accompanying drawings, in which:

Fig. 1 is a cross sectional view on a greatly enlarged scale, of' a. Woven fabric to serve as the base of a fabric embodying my invention, and a section of a bat or layer of suitable fibrous material so placed on a surface of the fabric as to be in position to be subjected to the initial step in the formation of a nap or pile on the fabric;

Fig. 2 is asimilar cross sectional view of the'fabric and bat after they have been subjected to a needling operation whereby a large number of loose fibres are caused to project through the meshes of the Woven fabric serving as a base;

Fig. 3 is a similar cross sectional view of the fabric after the excess of fibres has been removed, by singeing or otherwise, from the bat side of the fabric;

Fig. 4 is a similar cross sectional view of the fabric after a coating and impregnating layer of cement has been applied to the bat side to anchor the bat to the fabric;

Fig. 5 is a similar cross sectional view of the finished fabric after the fibres projecting through the fabric base from the bat side of the opposite or finished side have been napped to raise, ldisentangle, and straighten ythem and have been sheared to render them of substantially uniform length, and thus give a pile finish; and

Fig. 6 is a similar cross sectional view of a fabric finished similar to that of Fig. 5 to which a coating of suitable material, such as Gthe cellulose ester compositions or rubber compositions commonly used for making arness and stlength are desired.

tificial leather or water proofed surfaces, has been applied to the pile or nap surface of the fabric.

In the drawings, the same reference numerals refer to the Sallie parts throughout the several views.

In my present invention, a mass of loose fibres is attached to a woven fabric base, by placing a layer or bat of loose fibres on the side of the fabric opposite that on which the ile, or nap, er other finished surface is to fie formed, pushing portions of the fibres of this bat through the interstices of the fabric while leaving the remaining portions enmeshed in the bat, and then anchoring the portions of the fibres on the hat side so that they cannot be pulled through the fabric or otherwise dislodged. ln anchoring the fibres on the bat side of the fabric I preferably imprcgnate these eun'ieshed portions on the bat side by means of a suitable cementing composition to attach them fo each other and secure them to the fabric base. rlhe portions projecting through the fabric to the opposite or finish side are thus lsecurely anchored and may then be subjected to combing, shearing, or other finishing operations without danger of looseningr the fibres, or may serve as a secure anchorage for a coating applied to the finished surface to form an artificial leather or water proof coating.

As the fibres are thus anchored independently of the weave of the fabric base., a pile or other desired finish may be formed on a wide variety of fabrics. and coarse, loosely woven fabrics` such as burlap, may be used for this purpose, particularly where cheap- The bat may be made of a variety of fibres depending on the type. and quality of finish desired, but preferably consists of wool or hair or a mixture of wool and hair, the fibres of which are loosely intermeshed with each other. This bat is laid on the under or hat side of the fabric and blunt or barbed needles are repeatedly forced through the bat and the fabric, catching portions of the fibres and forcing them through interstices iu the fabric base While the remaining portions of the fibres are left intermeshed in the hat. There is thus left on the bat side of the. fabricl the main portion of the fibres in a loosely infermcshcd condition while from this bat there extend through the pores or meshes 'of the fabric, short end portions, or loops, of fibres held loosely in position on the base by the length which is enmeshed in the bat on the opposite side of the fabric. Although each fi )re projecting through the meshes .of the fabric has a length enmeshed in the bat en the opposite-side, the mere needling operation does not of itself secure the fibres to the base with sufficient strength to enable the projecting ends to be subjected to combing or napping or other desired finishing treatments without danger of pulling the fibres completely, 01` very largely, through the fabric.

The portions of the fibres remaining in thc bat are, therefore, then anchored or secured to each other and to the fabric base by impreffnating them and the adjacent surface of tie base with a suitable cemeuting composition, first removing, if necessary'or desirable, the excess of fibres from the bat side from which-the needling was done. This cementing composition may be either a pyroxylin composition or rubber cement and may not only serve to anchor the fibres to each other but may render the finished product water proof. A slow curing rubber cement is preferably used which impregnates each of the individual fibres, and after the solvent has evaporated from the cement,

leaving each fibre in the bat 'enclosed in a layerl of rubber, the mass of fibres and rubber is formed into a unitary mass by pressure. A backing of a clothlike or fibrous appearance may then be formed or an desired finish given to thc bat side of t e completed fabric.

'lhe anchorage thus given to the fibres is so firm and secure that the fibres on the side of the fabric opposite the bat may be subjected to combing, napping, shearing or other treatment to produce any desired finish. In forming a pile or nap finish, the fibres are combed to straighten them and cause them to lie in the same direction substantially parallel to each other and at right-angles to the base. fabric, and are usually subjected to a shearing operation by which they are rendered of a substantially uniform height. 'lhe fibres may be sheared close to the fabric base and serve as au anchorage for a continuous coating of a pyroxylin or rubber composition, the ends of the fibres being embedded .in and covered by the coatilnr and securely anchoring thev coating to the lfabric base. Or the projecting fibres may be pressed and left with a finish resembling that of a woolen cloth. In each case a bat of fibres suited to the finish desired, is selected.

Referring more particularly to the accompanying drawings to illustrate the product and method, a bat 10 of loose fibres is placed on the. surface of a woven fabric 12 op )osite that which is to serve as the finished suie, the position of the bat being that indicated in Fig. 1. The fabric 12 may be burlap, heavy cotton goods of open mesh or even thin sheeting. The bat 10 is then acted on by a large number of needles which repeatedly penetrate the mass of loose fibres and the meshes of the fabric 12 and carry the ends 14 of many of the fibres through to the opposite side of the fabric as indicated in Fig. 2. The thickness of the bat may now be. reduced to aldesired uniform thickness by removing unnecessary fibres by singeing or other means,

leaving the fabric and bat as indicated in Fig. 3. In this condition each of the fibres 14 extending through the meshes of the fabric has a length extending into and l ing in the bat but which is not secured therein with sufficient firmness to hold the fibres in place` against the pulling effect of combing.

A layer of rubber cement 16 is therefore applied to the bat 10, impregnating the fibres of the bat and under surface of the fabric base but preferabl not penetrating through the fabric 12 to t e opposite or finish side. After the solvent has evaporated from the cement, the remaining rubber, which is preferably a slow curing rubber, is pressed t0 unite the fibrous mass into a unitary body as indicated in Fig. 4. This rubber cement has the effect of uniting each fibre in the bat to the other fibres so that the projecting ends on the finish side of the fabric cannot be pulled out unless sufficient force is used to destroy the fabric.

To form a pile or nap fabric, the fibres 14 are then combed, brushed or tigered and sheared leaving the fibres straightened and extending from the meshes of the fabric 12 in tufts or bunches 18, which joinand extend to a uniform level 20 above the fabric 12, in the manner of a pile fabric as -indicated in Fig. 5. The fibres may be sheared very close to the base and embedded in a coating 22. of suitable composition such as pyroxylin or rubber composition which completely covers the fibres and which may be finished in any desired manner. The ccmenting or coating layers 16 and 22 may penetrate to each other in the base fabric or merely coat opposite napping or sides of the base in accordance with the specific mode of treatment.

ln some cases. it may be desirable to provide this fabric with a cloth finish on the back or bat side and, where such is the case, a layer of sheeting or other suitable fabric may be doubled to the back side of the fabric produced in accordance with my method.

It will be observed that my improved fabric may resemble, in many characteristics, pile fabrics such as plush, velvet, or velour, in that it is provided with a large number of fibres projecting vertically from the base of the fabric. Such pile fabrics as have been made heretofore are comparatively expensive due to the complicated and intricate methods needed for this manufacture, but my improved fabric, while it has all of the desirable qualities of a pile fabric, may be produced at a materially lower cost. Furthermore, the impregnating layer which anchors the loose fibres to the fabric base may renderthe finished fabric waterproof andthis is a -very desirable characteristic not possessed by pile fabric as heretofore made. In the automobile industry, it is the practice, in many cases, particularly in connection with closed bodies, to use a plush, velour, or other pile fabric, as a lining for the inside of the body or for a lining for the decks or tops of automobiles, and my improved fabric is a materia] which is partlcularlypwell suited for this use and which answers all the purposes of this trade, notwithstanding the fact that it can be manufactured at a materially lower cost than the fabrics heretofore used for that purpose.

Moreover, my invention may be ap lied advantageously in the manufacture of) the ordinary pile fabrics as above mentioned, these fabrics generally being formed by looping or hooking the pile into the base fabric and shearing the same, instead of utilizing a single unlooped straight fibre as in applicants material. In the regulation pile fabric, the application to the base surface of the fabric of an impregnating coat of rubber cement, pyroxylin, or oxidized oil, serves the double purpose of providing a water-proofing material while, at the same time, increasing the hold of the base on the loop fibres. In fabrics so constructed, the pile is firmly anchored and cannot be readily pulled out of the base, as is the case ordinarily in pile fabrics.

While the method is particularly adapted to the production of fabrics with a pile surface, it is capable of producing other surface effects. Vhen a pile ef'f'ect is desired, it is desirable to use fibres which are comparatively straight, such as calf or goat hair. If on the other hand a surface finish resembling cloth is desired, other types of fibres, such as wool are used which may be felted to a cloth-like surface.v

In this class of goods, the needled fibres are compressed and matted with the cementitions material which may be rubber cement or a composition including p vroxylin or any other substance forming a holding layer for the projecting fibres. Various fibres will be forced down toa flat configuration such `as indicated in Figure 6 of the drawings, and may receive subsequently an additional finishing coating to smooth the surface. In a subsequent operation it may be also calendered under pressure and the application of heat, this serving further to lay the fibres and to give the fabric a cloth-like appearance.

In the modified fabric above referred to, and in fact. in any type of fabric utilizing the needled fibre, there is no necessary limitation of the binding or cementing substance to a rubber cement, since other materials will give satisfactory service, such, for example, as pyroxylin, oxidized oils, and the like. Moreover. in the cloth finish modification, I may employ a rubber composition on both sides or pyroxylin or oxidized oils on both sides, or I may utilize rubber on one side andoil or pyroxylin on the other, the specific coating material used depending upon the finished effect desired and somewhat upon the base material employed and other considerations which may arise in the manufacture of the product.

Note should be made further, of the advantageous use of impregnating material on the base fabric and on the needled fibres of this fabric. l have found it in some instances, exceedingly advantageous to waterproof the needled fibres by utilizing a solution of aluminum acetate or similar water repellent., non-absorlant and non-capillary fluid impregnating in the fibre, so that in the completed fabric, there is no tendency therein to absorb moisture. This water-proofing treatment of the fibres of the fabric is advantageous in either the pile construction or the cloth finish construction. It. is under stood` of course, that in addition to the waterproofing of the fibres of the fabric, one. or both sides thereof may be coated with an additional water-proofing coat of rubber, pyroxylin, oxidized oils or other substance having similar properties.

As changes of construction may be made within the scope of my invention, it is desired that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
