2 Claims. (Cl. 2-143) This invention pertains to apparel collars, for example shirt collars, more especially to a soft collar for sports wear or the like and to a method of making such collars which results in uniformity of product, and is a collar which, after laundering has a smooth surface devoid of ridges. Such soft collars are usually attached directly to the shirt without any intervening neckband and are sometimes Worn open and at other times closed. In the latter event,'i`n'particular, it is desirable that the collar, and especially its forward orV Wing portions, have sufficient inherent stilness to provide a good appearance. On the other hand it is undesirable that the fold line be unduly stijf. It has heretofore been proposed to stilen the front or wing portions of a soft collar by associating spaced, independent stii'fener elements of one or another material with the customary liner ply, but heretofore the usual practice in the employment of independent stilfening elements has been to sew them to the liner or one of the outer plies by sewed seams, after which the liner and outer plies are assembled and united and the collar is turned. However, the formation of a sewed seam for uniting the margin of the stiener element (usually a piece Yof textile fabric) to the liner or other ply creates a narrow rib (the sewing stitches adding to the effective thickness at the location of the seam), whose presence is manifest in the finished and laundered collar as a perceptible ridge in the under surface of the collar. Moreover, in laundering, the threads of the sewed seam tend to shrink and thereby to cause a crinkling of the margin of the stifener piece which accentuates the irregularity of the outer surface of the collar resultant from the presence of the seam itself. Laundering of such a collar in such a way as to avoid such surface irregularities is difficult, particularly at the rear part of the collar where the proximate vertical edges of the stiffener pieces are adjacent to `each other. i

The present invention has for its principal object the production of a collar of the above type useful, for example, as a collar for a sports type shirt, having a certain degree of stiffness at the front or wing portions, at least, but having a normally flexible fold line; which may bevlaundered in customary manner and without particular care and which,ewhen so laundered, has a smooth outer surface devoid of visible undulations or irregularities resultant from the inclusion of the stiffener elements. further object is to provide a novel method of making collars having the above characteristics, `and which except with respect to the particular features of novelty herein disclosed, follows a usual and customary practice in the manufacture of collars. Other and further objects and advantages of the invention will be pointed out in the following more detailed description and by reference to the accompanying drawings wherein Fig. 1 is a fragmentary perspective view of a shirt having a collar embodying the present invention;

Referring to the drawings, the numeral indicates a t shirt having the collar 12 of the present invention attached thereto in conventional manner, the collar being shown in open position. This collar, as illustrated in Fig. 6, comprises the front or outer ply 13, the liner ply 14, and the rear or inner ply 15. These several plies'are of customary material employed in the manufacture of shirt collars, for example a fine textile fabric, the several plies being of approximately the same size and shape, as is usual, and being united along the end edges of the collar and along the free edge of the collar by a sewed seam 16, the collar being turned after the formation of this seam so as to provide the finished edge 17 (Fig. 6). The opposite edges of the several plies are united by the seam 13 to the front and rear plies 19 and 20 of the shirt body, all in conventional manner.

ln accordance with the present invention, the liner ply 14 which, as above noted, is of customary material and contour, is provided with stilfener means before it is assembled with the other plies. As illustrated in Fig. 3, stifener elements 21 are arranged to stiffen each of the front or wing portions of the collar. The stiifener element 2l, being designed for use a-t the end portion of the collar, is shaped to conform generally to that of the end portion of the collar but is of less length and width than the liner ply. Thus the stilfener element 2l, aS shown in Figs. 3 and 4, has the top edge 23, the lower edge 24, the front end edge 22 and the inner or rear edge 25. Preferably these edges are pinked or scalloped in order to minimize irregularities in the outer surface of the completed collar. However, the use o f pinked or scalloped edges is not essential. As illustrated to magnified scale in Fig. 3, the material from which the stiffener element 21 may be made, is a textile fabric having inclusions of yarn 26 consisting, for example, of a cellulose derivative which is normally non-tacky but which is inherently capable of becoming temporarily adhesive when heated or treated with a solvent, these yarns being preferably interspersed among ordinary textile yarns 27.

Having prepared stiifener elements, such as illustrated in Fig. 3, the liner ply 14 is laid down on a flat surface and the stiffener elements are arranged, as shown in Fig. 4, where two such elements are illustrated, one at the right-hand end and the other at the left-hand end of the liner ply 14. The stiffener elements 21 are so arranged that the edges 22,` 23 and 24 of the stiifener element are spaced from the adjacent edges 28, 29 and 30 respectively of the liner ply 14 with the proximate or rear edges 25 of the two stilfener elements spaced `apart at the center or rear portion of the liner ply so as to leave an area 34 of the liner ply uncovered. By thus arranging the stiiener elements, marginal areas 31, 32 and 33 of the liner ply 14 are left exposed and it is these portions of the liner ply which are caught in the seams 16 and 18 in assembling and uniting the several plies of the collar and in attaching the collar to the shirt body.

Having arranged these stiffener elements 21 on the liner ply 14, as shown in Fig. 4, they are then treated to bond them adhesively to the liner ply. If the stiener elements be of the material above suggested and as illustrated in Fig. 3, it may be sutcient merely to apply heat and pressure to bond them to the liner ply or alternatively to lay over the stiifener elements a pad moistened with a solvent for the threads 26 and then to apply heat and pressure. If the stiiener element 21 be of ordinary textile fabric, adhesive or cement of appropriate type will be applied to the stiifener element and, if desired, also to the liner ply, before 4laying the stilener element down on the liner ply. Then, by proper treatment, for example the application of heat or by merely allowing the parts to stand for a suitable time in the air, the adhesive is caused to set, thus permanently bonding the stilfener element to the liner ply. In any event, the stiener element should be firmly bonded by the adhesive, throughout its entire area, including its extreme marginal portions, to the liner ply. Preferably the stiling means is located between the liner ply 14 and the rear or inner ply 15 of the collar, thus further minimizing the possibility of the formation of irregularities on the outer or exposed surface of the completed collar when the latter has been laundered.

While stitfener elements of a certain shape and dimen-sions have herein been illustrated, it is obvious that stiffening means of other form and occupying more or less of the area of the liner ply may be employed, if desired, in lorder to obtain desired stiffening at selected portions of the collar. However, whatever the shape or dimensions of the stitfener element may be, the stiffening should not extend into the margins of the liner ply so as to be caught by the seams 16 or 18, it being essential to the present invention that the stiifening means be united to the liner ply by adhesive only and that the stiifening means be otherwise entirely free from mechanical connection to the other collar parts.

While one desirable embodiment of the invention has herein been illustrated by way of example it is to be understood that the invention is broadly inclusive of any and all modications falling within the scope of the appended claims.

I claim:
