Description

Knit slide fastener

The present invention relates to a kind of knit slide fastener that has the continuous connector of the connector supporting part in the longitudinal edge that inweaves (and along) this knit slide fastener band when coming the Woven slide fastener band.

Common slide fastener (for example disclosed the sort of among day disclosure special permission No.38-11673) contains a zipper strip that weaves and have a longitudinal edge portions with the line and the liner parallel of chain type tissue, and inweaves the connector of a row by the fibroplastic continuous coiling of nylon monofilament along above-mentioned longitudinal edge portions.This nylon fiber is laterally introduced vertical belt edge part and form one in the Woven slide fastener band and arranges the coiling formula connector that inweaves continuously in the above-mentioned chain type tissue.U.S. Patent No. 5,035,125 disclose another kind of known knit slide fastener, and this slide fastener contains a zipper strip that weaves with the line and the liner parallel of chain type tissue and a row fibroplastic continuous connector of plastic monofilament by a longitudinal edge portions that inweaves (and along) zipper strip.In above-mentioned longitudinal edge portions, liner weft yarn and chain type tissue along two stringers operation interweave with the upper and lower leg of pushing down connector downwards and, it also interweaves to push down the lower support leg of connector downwards with the chain type tissue that moves along a contiguous stringer.

Above-mentioned common knit slide fastener is a kind ofly to contain zipper strip that a line liner parallel with the chain type tissue interweaves and longitudinal edge portions introducing above-mentioned zipper strip inweaves the slide fastener of the sort of type of plastic monofilament fiber of the continuous coiling formula connector of (and along) this longitudinal edge portions to form a row.In first kind of above-mentioned knit slide fastener, connector in a row is to fix by the sinker loop in order to the chain type tissue of the ground-tint structure that forms zipper strip.Because the chain type tissue can longitudinally elongate, therefore, the part that is fixedly coupled is unsettled dimensionally, and, when being elongated, the chain type tissue may deform.The connector that this row has been out of shape can not guarantee that the level and smooth interlocking between connector with another row and its coupling engages.In second kind of above-mentioned knit slide fastener, the needle loop of chain type tissue only interweaves with the liner parallel that extends through vertical belt edge part, and it also is the ground-tint structure that the chain type of pushing down the connector leg is downwards organized.The chain type of this structure is organized also and is longitudinally elongated easily, therefore, can not guarantee that connector has enough dimensional stabilitys, so be difficult to make the interlocking that reaches level and smooth between the two opposite rows connector to engage.

Above-mentioned shortcoming in view of prior art, an object of the present invention is to provide a kind of knit slide fastener that has the continuous connector of a row, this row's connector can be fixed on the longitudinal edge portions of banding firmly with high dimensional stability, and closely contact with the ground-tint structure and keep stable fixed position at any time, because of than, the accidental accident of splitting takes place in the time of can keeping can not using slide fastener as a required function of slide fastener.

To achieve the above object, provide a kind of knit slide fastener according to one aspect of the present invention, this knit slide fastener contains one by a kind of zipper strip through compiling the ground-tint structure and partly forming along its connector supporting of a longitudinal edge, with one come the continuous connector that partly inweaves along its connector supporting in the process of this zipper strip of braiding, each above-mentioned connector all has a pair of upper and lower leg.The improvement of this knit slide fastener is: this slide fastener has many according to sewing the parallel line side by side that knot chain type tissue inweaves above-mentioned connector supporting part, the line that each root is above-mentioned sews knot chain type tissue contains the sinker loop of the part of a series of above-mentioned ground-tint structure that is configured to support and fix above-mentioned connector in a row, needle loop with the pin braided wire circle of one group of continuous vertical interlocking of a series of formation, this group needle loop is to arrange like this: in per two adjacent lines, the last leg of a previous needle loop and an above-mentioned connector is overlapping, a follow-up needle loop between an above-mentioned connector and adjacent another connector in the space that forms near ground-tint structure place so that make above-mentioned previous needle loop bend to reverse U shape extended loop walk around this connector on, lower support leg.

Provide a kind of according to another aspect of the present invention and contained one by forming and have along the connector supporting zipper strip partly of its longitudinal edge through compiling the ground-tint structure, with one come the continuous connector that partly inweaves along its connector supporting in the process of this zipper strip of braiding, each connector all has a pair of upper and lower leg.The improvement of this knit slide fastener is, it has the many parallel lines side by side that knot chain type tissue inweaves this connector supporting part of sewing according to the double knitting structure, the line that each root is above-mentioned sews knot chain type tissue all contains the following needle loop of continuous vertical interlocking of the part of one group of above-mentioned ground-tint structure that is configured to support and fix above-mentioned connector in a row, with one group continuous, the last needle loop of vertical interlocking, above-mentioned last needle loop is to arrange like this, in per two adjacent lines, the last leg of a previous needle loop and an above-mentioned connector is overlapping, follow-up needle loop between an above-mentioned connector and adjacent another connector in the space that forms near above-mentioned ground-tint structure place so that make above-mentioned previous needle loop bend to reverse U shape extended loop walk around this connector on, lower support leg.

Above-mentioned connector supporting part preferably also contains at least one according to tricot stitch line braiding and that have a series of sinker loops, and each sinker loop is the last leg of the corresponding connector of extend through all.

Each connector inweaves in the ground-tint structure in such a way, and promptly each root is sewed the knot chain type and organized the previous needle loop of line to be become extended loop to walk around the reverse U shape of the upper and lower leg of this connector.Therefore, the connector that inweaves clamping stably location, and form with the ground-tint structure and to contact closely, simultaneously, the upper and lower leg of connector remains on the positive perpendicular direction with the ground-tint structure.Because follow-up needle loop is all interlocked with the knitting arc of its front and is pulled to the ground-tint structure, so between each space that forms between two adjacent connectors, have only single coil, and sew the knot chain type and organize the needle loop of line to be pulled to the ground-tint structure tightly.The result, thereby connector can keep stable stationary state can keep the required level and smooth connection effect of slide fastener frequently, formed a space in other words owing between every pair of adjacent connector, have the part of spill, so connector in a row can be crooked along the longitudinal direction at an easy rate.Just because of this improved flexibility is arranged, the material that connector in a row can fitly be fixed to a kind of softness is for example on the dress material.

Use with sewing the line of tying chain type sewing the line of tying tricot stitch, and it is placed under the situation of upper surface of connector in a row, sew the line generation lateral displacement that the line of tying tricot stitch can prevent to sew knot chain type tissue.In addition, the upper surface of extend through connector in a row sews the line of tying tricot stitch and can prevent effectively that slide fastener from accidental cracking (this situation is subjected to taking place probably along perpendicular to the external force of the general plane of slide fastener the time at a pair of connector in a row that engages one another) taking place.In this embodiment, if necessary, the line of sewing knot chain type tissue that is used for fixing connector in a row with sew the line of tying tricot stitch and preferably have than big rugosity and the percent thermal shrinkage of litzendraht wire that is used for forming zipper strip.To stand the situation of heat-set treatment for the finished product slide fastener, adopt thicker and line advantageous particularly that percent thermal shrinkage is bigger, when carrying out heat-set treatment, these lines can produce thermal contraction and fix connector tighter, thereby improved the dimensional stability of connector, the state that keeps simultaneously its high stable again, this just makes connector obtain level and smooth linkage function.
