Description
~0~6~8~
The present invention relates to a warp-knitted stringer tape for slide fasteners which is formed with synthetic fiber yarnsO
There have been devised various warp-knitted stringer tapes for slide fasteners which are formed with synthetic fiber yarns. Since the stretch of such stringer tapes must be minimized, it is necessary to select those yarns which are highly resistant to stretchabilityO Accordingly, the stitches in such knitted tapes are taut and tight, and the faces and backs of the tapes are relatively hard and slippery~
The prior stringer tapes therefore tend to slip rela-tively to garments while they are fed and sewn together by the sewing machine, with the results that the tapes can be skewed or displaced when attached, and the sewn tapes are prone to become wrinkled or puckered, a condition that is harmful in appearance and function to the slide fasteners.
Further, the stringer tape when shifted while being sewn causes the sewing machine needle to fail to penetrate at a selected interwale groove of the knit structure and to hit an adjacent wale, resulting in a curved line of stitching and a breakage of the sewing needle.
It has been known to lay textured yarn as weft threads in the warp-knitted tape in an attempt to prevent the pucker-ing of the tape. However, since the inlaid textured yarn does not project from the waled face of the tape, such laid-in tape has a limitation in choosing its surface to be applied against the garment and thus has only met with a partial success.
: ~
:.
An object of the present invention is to provide a warp-knitted stringer tape for slide fasteners which has a face and a back t~at are relatively rugged and are applicable against the garment for sewing operation.
Another object of the present invention is to provide a warp-knitted stringer tape for slide fasteners which has a central web region that impose no positional limitation on the sewin~ needle when it penetrates the web region.
Still another object of the present invention is to provide a warp-knitted stringer tape for slidefasteners which has a central web region that is elastic enough to allow smooth sliding movement of the slider along the tape.
In general terms, the present invention provides a stringer tape for slide fasteners, comprising a warp-knitted structure made of synthetic fiber yarns including textured yarn and non-textured yarn, said warp-knitted structure being composed of a plurality of different patterns of stitches forming wales, at least one of said different stitch patterns being formed with said textured yarn, the stitch patterns other than said at least one stitch pattern being formed with said non-textured yarn, said warp-knitted structure including a pair of spaced edge region and a web region extending between said spaced edge regions, said web region comprising at least two of said different stitch patterns, said two stitch patterns in said web region consisting of tricot stitches formed with non-textured yarn and single cord stitches formed with textured yarn to render said wales relatively soft, flexible, and penetratable by a sewing needle, the majority of said different stitch patterns in said edge regions being formed with said non-textured yarn, and the stitches of said textured yarn having portions bulging on both surfaces of said warp-knitted structure over said wales.
~ - 3 -1~961~9 In accordance with another aspect of the invention, the warp-kn~tted structure comprises a double-faced fabric made on two needle bars, at least one stitch pattern being preferably formed on one of said two needle bars.
According to a further feature of the present invention, stitch patterns in the edge regions are formed solely with said non-textured yarn. The non-textured yarn stitch patterns may include chain stitches and tricot stitches disposed in said edge regions of said web region. According to a yet another feature of the present invention, said web region further includes a stitch pattern consisting of chain stitches formed with textured yarn. In accordance with a still further feature of the present invention, said web region further includes a stitch pattern consisting of chain stitches formed with non-textured yarn.
The above and other objectq and advantage~ of the present invention will become apparent from the following description when taken in conjunction with the accompanying drawings.

In Figs. 1 and 2, a stringer tape 10 for slide fasteners which is constructed in accordance with the present invention is of a warp-knitted structure made of synthetic fiber yarns ; including textured yarn 11 that i9 mechanically bulky, crimp-ed, soft, and stretchy, The stitches 12 which are formed with the textured yarn 11 thus project from or bulge on both the face 13 and the back 14 of the warp-knitted structure.
The synthetic fiber yarns also include non-textured, normal yarn 15 that cooperates with the textured yarn 11 in making up the stringer tape 10.
; A stringer tape 16 as shown in Fig. 3 includes a pair of spaced element-supporting edge regions 17,18 and a central web region 19 extending between the edge regions 17,18.
The stringer tape 16 is formed with chain stitches 20 having a stitch pattern of 1-0/0-1, tricot stitches 21 having a stitch pattern of 1-2/1-0 (under 1 over 1), and single cord ,~ ., 1~961~9 stitches 22 having a stitch pattern of 0-1/4-3 (under 3 over 1). Additionally, reinforcing warp threads 23 and 24 are laid in two interwale grooves defined along one of the edge regions 17,18 of the stringer tape, the inlaid warp threads 23,24 having a stitch pattern of 0-0/0-0. The tricot stitches 21 disposed in the edge regions 17,18 and the web region 19, and the chain and single cord stitches 20,22 in the edge regions 17,18 are formed with non-textured yarn 25, and the , .
chain and single cord stitches 20,22 in the web region 19 are formed with textured yarn 26.
Since the textured yarn 26 has a greater stretchability and bulkiness, the stitches 27 of the textured yarn 26 are loose relatively to those of the non-textured yarn 25 just after the warp-knitting has been completed. Further, since the degree of shrinkage due to finishing processes such as heat-setting and dyeing is greater for the non-textured yarn 25 than for the textured yarn 26, the stitches 28 of the non-textured yarn 25 become additionally tight and the stitches 27 of the textured yarn 26 remain relatively loose after such finishing processesO The finished stringer tape 16 has the textured yarn stitches 27 bulging on its face and back due partly to such loosely looped stitches 27 and due partly to the bulkiness of the textured yarn 26. Accordingly, the surfaces of the stringer tape 16 are rugged and have a relatively large coefficient of friction, and the tape 16 can be prevented from slipping on the garment during sewing operation, no matter which surface of the tape 16 is held against the garment.
' ~ _ 5 _ , : .
1~96~8~1 The longitudinal and transverse stretch of the edge regions 17,18 is held at a minimum by the chain stitches 20, tricot stitches 21, and single cord stitches 22, all const-ructed with the non-textured yarn 25. With the inlaid warp threads 23,24, the edge region 17 is particularly stable dimensionally to provide rigid support for fastener elements.
The web region 19, however, is relatively stretchable warpwise andcoursewise because of inclusion therein of the textured yarn 26 as the chain stitches 20 and the single cord stitches 22~ The stretchability of the web region 19 makes the stringer tape 16 elastic enought to allow the fastener elements to ;~ be smoothly introduced into the slider as it moves for closing the slide fastener. Further, with the textured yarn 26 thus knitted in the web region 19, the web region 19 is uniformly ~` 15 soft and flexible, so that there will be only a small degreeof resistance to the passage therethrough of the sewing machine :`
needle, and hence a line of stitching can be made as straight as possible.
Fig. 4 shows a modified stringer tape 29 in which chain stitches 30, tricot stitches 31, and single cord stitches ~` 32 in the web region 19 are all formed with textured yarn 33O
With this structure, the web region 19 has its both surfaces more roughened by the textured yarn stitches for an increased coefficient of friction, and the web region 19 is more flexible for less resistance to the penetration therethrough of the sewing needle.
According to Fig. 5, the web region 19 is devoid of any chain stitches, and is formed only with tricot stitches iO96~1~
34 and single cord stitches 35, both of textured yarn 36.
Therefore, the web region 19 is much more flexible, and contraction or shrinkage thereof due to shifting by the sewing threads of the stitches can be substantially done away witho In Fig. 6, the web region 19 comprises only single ` cord stitches 37 of textured yarn 38 and tricot stitches 39of non-textured yarn 400 Further, each edge region 17,18 ,i, -~ is formed with chain stitches 41 and tricot stitches 42, both ~ ,r ' :
made of non-textured yarn 43, and the single cord stitches 37 of the textured yarn 38. According to this modification, the textured yarn stitches project from the stringer tape ,~ over its entire width, so that the stringer tape can be pre-: ,-~;~ vented from slipping on the garment more effectively. In addition, the web region 19 is coarse and permits smooth penetration of the sewing needle therethrough, and shrinkage ,~ thereof due to sewing operation is substantially eliminated.
