DESCRIPTION OF THE PREFERRED EMBODIMENTS
Shown in Fig. 1 is a slide fastener indicated generally at 10, which incorporates therein a variable dye guideline according to the presen~ invention. The slide fastener 10 includes a pair of mounting tape 12 and 14 upon the adjacent edges of each of which is mounted a chain of slide fastener coupling elements 16 and 18. A slider 20 is entrained in the chains of slide fastener elements 16 and 18 and is movable up and down thereupon to engage and disengage the coupling elements of the chains. A respective guide line 22 and 24 is defined on the respective mounting tapes 12 and 14. The guide lines 22 and 24 are used, in this instance, to aid in the correct installation of the slide fastener 10 in a garment.
A first method of forming the guide lines 22 and 24 is illustrated in Fig. 2 which is a close up ~iew of a fabric used in one of the mounting tapes 12 or 14. The fabric of Fig.
2 is warp knit having a plurality of warp loop threads 26, 28, and 30, and a plurality of weft-like warp threads 32, 34, 36, 38, and 40. The fabric is knitted in a conventional manner on any one of a large number of warp knitting machines well known to the art. At the time of knitting all the threads 26, 28, 30, 32, 34, 36, 38 and 40 are in an undyed or white state. Th~ warp loop threads 26 and 30 and the weft-like warp threads 32, 34, 36, 38 and 40 are all of a single type of textile material, as for example polyester, while a single 1hread, in this case the warp loop thread 28, is of a second material, such as acrylic,which has à different dye absorption characteristic from the first textile material. Sometime following the knitting of the fabric of Fig. 2, the fabric is dyed the color desired for the particular application, and the polyester threads 26, 30,32, 34, 36, 38 and 40 all dye a relatively dark shade of the dye color while the acrylic warp loop thread 28 remains white or is dyed a very light shade of the dye color due solely to the relative absorptioncharacteristics of the two thread materials. Thus a white or at least a very light guide line is created in the fabric of Fig. 2 by a warp loop thread.
The use of the warp loop thread 28 for creating the guide line results in a guideline that is plainly visible on both sides of the fabric. If it is desired that the guideline be partially hidden on one side of the fabric, so, for instance, it will not show in the completed garment, it is possihle to utilize one of the weft-like warp threads as for example thread 36, as the guideline threads. The warp loop thread 28 would be of a material similar to the other threads while the weft-like warp thread 36 is of the different material. Inasmuch as each of the warp threads 26, 28 and 30 passes twice behind the weft-like warp thread 36 during each of their loops and only once in front of it, the guide line is clearly more visi~le ~rom the front of the fabric of Fig. 2 than from the back.
Shown in Fig. 3 is a variety of knitting patterns that can be used to create a guide line according to the present invention. The patterns shown in Figs~ 3 a through e are generally warp loop patterns that create guide lines visible on both sides of the resultant fabric. The patterns in Figs.

Shown in Fig. 3 is a variety of knitting patterns that can be used to create a guide line according to the present invention. The patterns shown in Figs~ 3 a through e are generally warp loop patterns that create guide lines visible on both sides of the resultant fabric. The patterns in Figs.
3 f through j show generally weft-like patterns which create gu~de lines in the fabric visible only on one side of the fabric or, at least, more visible on one side than the other.
Shown in Fig. 4 is an alternative method for forming the guide lines of the present invention. A fabric has a plurality of warp loop threads 42, 44, 46 and 48 and a plurality of weft-like warp threads 50, 52, 54, 56, 58 and 60 all of a single thread material such as polyester. The fabric is again knitted in a conventional manner well known to the art. However, during the knitting a laid-in guide line thread 62 is laid in the fabric such that the warp loop thread 46 loops over it and secures it to the fabric. The laid-in thread 62 is of a second material having adye adsorption characteristic different from the first, as for example, nylon. The fabric after being knitted is then dyed and the laid-in thread 62 dyes to a darker hue than the remaining threads 42 through 60, due to the generally greater adsorption of dye bY nylon compared to polycster. The guideline created by the laid-in thread will be visible only on the front side of the fabric of Fig. 4 inasmuch as it lies on top of the weft-like threads 54, 56, 58 and 60 and will therefor be hidden from the reverse side of the fabric.
An alternative form of the laid-in thread guideline is also shown in Fig. 4. A laid-in guide line thread 64 is shown which could be inserted in the knit instead of the laid-in thread 62. The laid-in thread 64 passes through every loop of ~053475 the warp loop thread 42 and again is only visible on the t~p side of the fabric.
It is within the scope of the present invention that a woven tape could incorporate a variably dyed guide line. A single warp thread of the weave could be of a different thread material than the remaining threads in the weave thereby creating a straight guide line after dying along that warp thread.
It is also within the scope of the present invention that a wide variety of materials could be used for both the guide line thread and the threads in the remainder of the fabric. Table I lists a few of the many possible combinations of materials used to create the variably dyed guide line.

It is possible for more than one thread to be used in a single guideline. Thus a guideline of the width of several wales could be constructed by using several threads of the second material. Also it is envisioned that more than one guideline counld be incorporated into a single fabric. Thus in the case of a slide fastener mounting tape a variety of spaced guidelines could be utilized, with each positioned for a specific porpose, i.e. one guideline for installation in a skirt, another guideline of the slide fastener is to be installed in a pair of pants, etc.
Thus by utilizing the present invention, a sewing guideline is created that will become visible after the mounting tape fabric is dyed. It is advantageous in that - the tape can be dyed any one of a variety of colors for the 15 guide line to be visible. The process requires no new secondary steps in the manufacture of the tape and requires no degeneration of any of the tape's normal properties. The width of the guideline and its visibility on one or both sides of the tape is controllable by the selection of the 20 particular thread for the guideline. Also, the guide line will inevitably be straight and unerring inasmuch as it is an element in the knit of the tape and it will therefore also be immovable.
Inasmuch as many changes and variations in detail 25 are possible within the scope of the present invention, it is intended that the above description and accompanying drawings be interpreted in an illustrative rather than a limiting sense.
