Serial No. 28,386

1 Claim.

The subject-matter of the present invention relates to processes for producing a neck tie lining from an all cotton textile woven fabric, and the object of the invention is to transform a purely 5 cotton fabric, tie lining fabric, which if used in its original state as a neckwear tie lining, would not hold its permanent shape, but would curl up and twist as a result of climatic conditions, into a tie lining with its structure so modified as to make it sufiiciently rigid by said processes, to make it a superior product for use as a tie lining which will hold the tie in permanent shape regardless of use or weather changes. The treated fabric by said processes is improved in its appearance and wearing qualities, giving superior service and resembling a tie lining of much finer quality and value.

This process may be applied to any cotton cloth made of all cotton warp and filling, and from the cheapest quality to the best quality of yarn, which may also vary considerably in the number of picks per inch, as well as in width, including sheetings, beach cloths, osnaburgs, organdies, twills and the like.

The process comprises certain definite steps in the treatment of the cotton cloth after it has left the looms and has been finished ready for sale to the trade. Thus the cloth has been through all the steps incident to the manufacture of a purely cotton woven textile fabric, which includes dyeing, napping, mercerizing, sizing and re-brushing. It matters not in what manner or sequence the cloth has been subjected to the aforesaid steps of bleaching, dyeing, napping, mercerizing, sizing and re-brushing.

WlL'le it is true that certain processes have been patented for producing particular effects in a purely cotton textile, still it is believed that the within described invention is novel as well as valuable, and certainly unknown to the neck tie lining trade.

Although the following and herein described methods are the best known processes and sequences used in the production of the finished article, it is not desired to restrict the same to the exact steps herein indicated, as it will be obvious that minor changes may be made without departing from the general tenor and scope of the invention as herein claimed.

My process is designed for use only with a woven textile made of a cotton Warp and a cotton filling, and not with a knitted or elastic fabric. Nor is it intended for use on a textile which contains Wool, rayon, mohair or other like material in the warp or the filling, or mixtures thereof.

The processed fabric invented by me may also be used as a coat front in the manufacture of garments for wearing apparel, and for other miscellaneous uses. Heretofore, coat fronts have been made of hair cloth to give them a neat and dressy appearance and hold the shape of the garment. This hair cloth usually becomes useless and the hairs get loosened from the fabric and fall out, making the garment unfit for further use, whereas when my processed material is used as a coat front there is no hair to fall out and the garment continues to keep its neat and drape appearance throughout the life of the material with which it is used. Furthermore my processed cloth can be used for said purposes at a price far more attractive to the trade than the materials heretofore needed for said purposes and manufacture.

In passing it should be noted that my superior tie lining which will not curl up, twist, puff and bulge in neckwear, may be cut on the bias, straight across the length or width of the material, semi-bias or otherwise, and give good results, and long and continued service.

The improvements which I claim as novel and Valuable are described substantially as follows:

Take any kind of cotton woven textile fabric, roll it on a cylinder, and then pass it from said cylinder to another cylinder through boiling water; thus bringing the cloth back and forth through the boiling water for 20 to 30 minutes, but not more, according to the particular cloth and structure. This process impregnates the threads of the yarn used in said cloth, with the sizing contained in said cotton cloth.

Next, the cloth is dried either on a hot cylinder or a perforated cylinder through which hot air is forced. Then the cloth is rolled through a machine with one roller hot and one roller cold, until it receives the required treatment. Then the cloth is reversed, with the side of the cloth that was on the cold roller being put up against the hot roller, and the side of the cloth which was exposed to the hot roller, placed upon the cold roller, until each side of the cloth gets sufficient treatment of hot and cold pressure against said rolls to obtain the desired effect.

The purpose of the cold roller is to spread out evenly through the cloth, the sizing which the boiling water impregnated into the yarn texture, and when rolled according to this process, this sizing is uniformly distributed as required to produce the superior non-twisting tie lining or coat front as previously outlined herein. It must be borne in mind, however that it requires sufficient skill in the handling of the aforesaid processes, not to remove all the sizing from the cloth on the one hand, while on the other hand, the use of the heat and cold processes must be so understood as not to chill the starchy sizing in such a manner as to make the cloth'stiff and spoiled by reason thereof. It is important that the process be done in such a manner as to transform the original cotton cloth, by the aforesaid skilled processes, into the finished product containing all of the advantages hereinbefore described.

These processes have nothing whatever to do with cloth shrinking.

When the cloth has become set as required, it is then ready to be put up in whatever form desired, either rolled on a round paper tube, or put up in a flat fold state, or doubled to half its width and rolled on a round tube, according to the particular use to which it will be submitted.

Having thus described my invention, what I claim as new and. desire to secure by Letters Patent, is:

The process of treating cotton cloth to prevent loss of shape, twisting, and curling, comprising: the successive steps of passing the cloth rapidly back and forth in boiling water for a period of twenty to thirty minutes, heat drying the cloth, pressing the cloth simultaneously with the application of heat and cold to the opposite sides of the cloth, and reversing the cloth so as to alternately apply the heat and cold to each of the sides, While undergoing the pressing operation.
