TEXTILE FABRIC AN D METHOD OF TREATING- THE SAME.
Application medium 12',
This invention relates to improvements in textile fabrics and the method of treating the same.
Previous to the present invention textile fabrics generally known as alpaca cloth had been manufactured in three different ways. First, the cloth has been woven with an all [grey cotton warp and grey viscose or arti 'cial silk and then piece dyed and printed; second, the cotton warp has been dyed with what are commonly known as direct colors and then interwoven with a white fillin of artificial silk; and third, the warp has een dyed with fast colors called indanthrene and vat colors in'the trade,
and woven with white artificial silk filling threads to produce a variety of-yarn dyed fabrics.
In accordance with the present invention, it is proposed to produce a yarn dyed washable fabric in which novel and characteristic designs may be obtained by the employment of developed or diazotized colors, portions of which are subsequently discharged or removed to form the completed design.
The inventive idea involved is capable of receiving a variety of expressions, one of which, for purposes of illustration, is shown in the accompanying drawing; but it is to be expressl understood that said drawing is employed merely for the'purpose of facilitatingthe description of the invention as a 'whole and not to define the limits thereof. reference being had to the appended tificial silk for the obvious reason that when dyeing, in the piece the silk would necessarily become dyed also. The second mentioned method could not be employed to produce the desired efiect in accordance with the present invention because the direct colors would fade and fail to withstand the finishing treatment in which steam boxes or other processes are used to dischar e portions of the color. The use of indant rene or fast colors, as stated in the third of the 1923. Serial No. 115,512.
filling thread which is usually the artificial silk. This silk may be left in. its original color, or may, if desired, be dyed a different color from that of the warp. The colors used for dyeing, as hereinbefore stated, are known as developed or diazotized colors which have the characteristics that'they may be discharged from the fabric to create designs therein and will be unaffected by ordinary washing methods.
The drawing is illustrative of one efi'ect which may be produced by the present method. The fabric 1 may be either of the kinds hereinbeforementioned with the warp dyed in the usual manner with a developed color or colors and thereafter interwoven with the filling thread of artificial silk in the event the latter material is used. The fabric is then treated to discharge or remove the color or colors in certain spots, as indicated at 2, so as to restorethe warp, if only the latter is dyed, at these places to its original color and thereby produce an efiect such as shown in Figure 1.
As above suggested, the silk may be left in its original color or may be dyed and then interwoven with the warp. In the latter color discharging agent, the dye from both the warp and filling or woof threads is removed.
What is claimed is:
i. The method of treating textile fabrics made. of cotton and silk threads, which comprises dyeing the warp with a developed color and thereafter discharging the color in spots to restore the warp to its original color at said s ots and thereby create a design in the fa ric.
2. The method of treating a washable textile fabric, which comprises dyeing the warp in'yarn form with a developed color,
W5 case when the fabric is treated with the Weaving said. warp with filling thread s ancl ors in said fabric. 7
3.. The method of treating a Washable teatile fabric, which consists in olyeing the Warp and Woof in yarn form with a deveh opecl' color, weaving said warp we Woof to fill into a fabric, and thereafter discharging the color in spots from sahi arp and oof to create a contrast in colors in saitlfahric.
4. As a new article of manufacture, a Washable cotton and silk fabric olyecl in yarn aeiaeoe iorm with cievelopeicolors which are dis 'chargeclin epots to create a design on the faloric. 1
5. As: a new article of manufacture, a Washable i 'ahric comprising cotton warp threads clyedi in yarn form with clevelopeoi colors, portions of which colors are 'ischarged to restore the Warp to its original color, anti'woof threads of silk interwoven with said Warp threads.
