The specific embodiment
The basic structure of fastener stringer of the present invention comprises: the chain band of fabric system, and it possesses band main part and sprocket installation portion, and this knitting chain band is made of warp knitting fabrics; Spiral helicine resin-made chain denture, it is sewn on the sprocket installation portion.Why using spiral helicine resin-made chain denture, be because it is lighter, and flexibility is higher, and taking in property is also better, so according to the invention ,the aim of the invention is to be suitable as most sprocket.As the resin of the material of chain denture, can enumerate polyester, nylon, polypropylene, acrylic fibers etc., but for sewing property better, the more high reason of the strength of materials, preferably use polyester.
Although the knitting yarn integral body of braiding warp knitting fabrics is attenuated, as slide fastener, from guaranteeing durable intensity aspect, preferably makes the outermost knitting yarn of sprocket installation portion enough thick.This is based on the elongation that suppresses the chain band, the reason of the sewing of sprocket is stablized and then improved to the width dimensions that makes band.Typically can use the knitting yarn that has 66dTex~275dTex, is preferably the yarn count of 78dTex~167dTex.Knit stitches, preferably adopt pillar stitch as used herein.This be because, by using pillar stitch, can strengthen the intensity of the edge part of sprocket installation portion, and can suppress the elongation of warp-knit tape, the installation exercise of zipper sprocket is easily carried out.
In addition, in the present invention, by to cross over the mode of 1 wale, dispose two for the needlework that the chain denture are sewn on the sprocket installation portion, thereby form two sewing threads.This sewing thread comprises: clip wale and be configured in the 1st sewing thread by the position in the outside of sprocket installation portion, and be configured in than 2nd sewing thread of the 1st sewing thread by the position of the inboard of sprocket installation portion.The 1st sewing thread is the sewing thread in the outside described later, and the 2nd sewing thread is the sewing thread of inboard described later.By the chain denture is installed by this way, thereby can make up because of the attenuate situation of decline of the sprocket installation strength that causes and stability of knitting yarn.Due to when the sprocket engagement of the fastener stringer of left and right, for the reason that makes the gap size stabilisation that produces between the edge part of facing mutually of each chain band, typically being used for the chain denture is sewn on two wales that needlework are crossed on the sprocket installation portion, is that the outside from the sprocket installation portion begins several the 2nd wales.
In view of the lightweight as the slide fastener of purpose of the present invention, fine rule is adopted in the needlework expectation.Fine rule also helps to improve the flexibility of slide fastener.If but meticulous, can not obtain to have installation strength and the stability of practicality.Therefore, preferably use yarn count to be the yarn of 100dTex~350dTex, further preferably use yarn count to be the yarn of 110dTex~250dTex.The yarn count of the running-on line that is used in combination with needlework is also identical.
The yarn count overstriking of any 1 knitting yarn in the knitting yarn of the sewing thread in the inner part of two sewing threads that in the present invention, leap formed like this.This refers to: the knitting yarn of crossing over inboard sewing thread can have many in band, but the yarn count of an overstriking 1 knitting yarn wherein.Specifically, use have 72dTex~330dTex, be preferably 78dTex~235dTex, the knitting yarn of the yarn count of 78dTex~167dTex more preferably.By the sewing thread of overstriking inboard, thereby can when the chain band be applied pulling force along its width, suppress the chain band and be torn off from sewing thread.As the knitting yarn of overstriking, for example can enumerate warp plain stitch's knitting yarn, satin knitting yarn and change two pins and organize knitting yarn.In addition, in the present invention, change two pins and organize knitting yarn to refer in each row and form respectively the knitting yarn that circle is done indentation configuration simultaneously on adjacent two wales.
Like this, enough thick with the outermost knitting yarn that is preferably the sprocket installation portion by any 1 knitting yarn in the knitting yarn that makes the sewing thread of crossing over the inboard, even thereby be in fact the yarn count of all knitting yarn than other, the scope of 56dTex~167dTex, typically in the scope of 66dTex~110dTex, more typically the above-mentioned knitting yarn in the scope at 66dTex~84dTex is thin, also can obtain to have the slide fastener of abundant intensity (particularly flatwise tensile strength).In typical embodiment, with respect to the outermost knitting yarn of sprocket installation portion and the yarn count of 1 above-mentioned thicker knitting yarn of crossing over inboard sewing thread, what make other is in fact more than the yarn count of the yarn count of all knitting yarn and above-mentioned thicker knitting yarn differs 10dTex, differ 20dTex in more typical embodiment more than, for example differ 10dTex~40dTex.
Describing " in fact " in above-mentioned paragraph is according to following reason.Mistake sprocket is arranged on the such faulty operation on main part with main part and sprocket installation portion in fabric chain band processed in order to prevent the user, can be on knitting chain band so that the warp knitting fabrics that can play a role as the sprocket installation portion to be set in the left and right sides as central authorities with main part.In this case, be not limited to have and be not used and unnecessary sprocket installation portion, belong to protection scope of the present invention.In addition, want to avoid technical scope of the present invention, and 1~2 thicker knitting yarns are used for such situation at the position beyond position that the present invention limits in form, also belong to protection scope of the present invention.
The width dimensions of the band of above-mentioned slide fastener is 11mm~13mm.Slide fastener is different according to its purposes, and the size of chain denture or band also can be different.Specifically, size, the width dimensions of band, the gauge of the size of the engagement head that engages with each other of the thickness of the line of spiral helicine chain denture, width dimensions, gauge and chain denture etc. are all different.This is because by the size of increase chain denture and band, thereby can improve flatwise tensile strength.Therefore, be 14mm~17mm in the situation that increased the size of band and made the width dimensions of this band, the yarn count that preferably will cross over any 1 knitting yarn in the knitting yarn of sewing thread in the inner part of two sewing threads is set as 235dTex~330dTex, and other that will be except the outermost knitting yarn of sprocket installation portion are in fact that the yarn count of all knitting yarn is set as 110dTex~167dTex.In addition, preferably the yarn count with the outermost knitting yarn of sprocket installation portion is set as 167dTex~275dTex, and the yarn count of needlework and running-on line is set as 250dTex~350dTex.
Sprocket installation portion and can use the knitting yarn of identical yarn count and material with main part, but also can change the knitting yarn that is used in main part and sprocket installation portion.In addition, no matter be band main part or sprocket installation portion, can change as required yarn count and the material of every kind of knitting yarn.
As the material of knitting yarn, polyester, nylon, polypropylene and the acrylic fibers etc. that can use slide fastener in the past to use always, but to use and the sprocket same material for knitting yarn, this reason of the aberration each other after reducing to dye is preferably used polyester.Knitting yarn also can be made of monofilament, and the multifilament that also can be formed by the monofilament bunchy more than two consists of.For example the yarn count of the multifilament of the monofilament bunchy of 50 5dTex formation is 1 one thread of 250dTex.
Itself can adopt known knitting technology weave the knit stitches of Woven chain band, does not limit the knitting technology weave that for example can adopt pillar stitch, warp plain stitch, satin and change two pin tissues.But, consider and alleviate the burden that brings braider when making the chain band form large volume, be preferably except using pillar stitch's knitting yarn and warp plain stitch's knitting yarn, also use from the satin knitting yarn and change two pins and organize a kind of knitting yarn selecting knitting yarn, amount to 3 kinds of knitting yarns and come the Woven chain band.Can be according to select to remain silent arbitrarily coil or open stich with required intensity.
In the preferred embodiment of fastener stringer of the present invention, the quantity that is intertwined with the coil (3 heavy coil knitted structure) of 3 knitting yarns in 1 coil accounts for more than 50% of quantity of all coils, more preferably accounts for more than 60%.Weigh the coil knitted structures by increasing by 3, thereby can obtain to make such effect of intensity, feel and large volume raising.If the coiled coil structure is more, because yarn attenuates, so can not obtain sufficient intensity, feel and large volume, if 4 heavy loop constructions are more, can not reach fully the lightweight as the slide fastener of original purpose.In addition, if excessively increase by 3 heavy coil knitted structures, the radical that is used to form the knitting yarn of coil increases, and can not reach fully the lightweight as the slide fastener of original purpose.Thus, preferably be intertwined with the quantity of the coil of 3 knitting yarns in 1 coil, less than 80% of the quantity of all coils.
After forming the slide fastener chain, pull head, the only upper and lower slide fastener of only completing are installed making a pair of fastener stringer engagement.By slide fastener of the present invention is sewn on various article, the switching utensil of slide fastener of the present invention as article wherein can be used for requiring the lace of light degree just, to article such as cardigan and windcheaters.
