Description
The present invention relates to can be used for the slide fastener on the article such as clothes and various suitcases.
Slide fastener generally is made of with slide fastener slippery fellow (closure element) chain closure member (doing tooth portion) and zipper strip (fabricbase).separately become two described zipper strip each subtend of separating end the chain closure member is set, slide by described slide fastener is foxy, described chain closure member engagement is closed or is opened.
Be broadly divided into as above-mentioned member: (hereinafter referred to as the independent chain closure member type) that each sprocket separates, or thick monofilament becomes spiral (hereinafter referred to as continuous chain closure member type).
Fig. 1 (a) is the front view of the independent chain closure member type slide fastener of expression, and Fig. 1 (b) installs the perspective view of appearance for explanation chain closure member 13 on zipper strip 11.Independent constituting of type chain closure member, described each sprocket on the chain closure member 13 is Y-shaped, and the chain foot section 13b by will being divided into the sprocket Y-shaped is sandwiched by the thick line 11a of zipper strip 11 ends or is fastening, and chain closure member 13 is fixed on the zipper strip 11.
Fig. 2 is the front view of the slide fastener of the continuous chain closure member type of expression.Chain closure member 23 is made of the spirality monofilament, makes the part that becomes sprocket outstanding and residual (chain toothed portion 23a) in this monofilament, and another part (23b of sewing portion) then sews up the end (separating end) of zipper strip 21 by sewing thread 24 and is fixed.
Then, by using above-mentioned independent chain closure member type or continuous any chain closure member of chain closure member type slide fastener foxy 22 is slided, and make the 13a of sprocket portion, the 23a of the chain closure member 13,23 of subtend become the chimeric or chimeric open and-shut mode of releasing.In addition, be provided with retainer 25, and be provided with retainer 26 down, deviate to prevent slide fastener slippery fellow 22 at the terminal part that slide fastener is opened at the terminal part of slide fastener locking.
Raw material as above-mentioned chain closure member 13,23 and above-mentioned sliding shoe 22 can use synthetic resin such as metal, nylon and polyester such as brass.And, then use the fabric of forming by synthetic fibers such as polyester and cotton fiber as above-mentioned zipper strip 21.
So far, handle about the environmental problem of synthetic resin article discarded object energetically.That is to say, even generally be synthetic resin is imbedded underground, can not be still residual by the edaphon decomposition, in addition, even during with its burning disposal, still have problem, worry to produce poison gas owing to ignition temperature is high, therefore the waste treatment problem that just begins one's study and be not above-mentioned synthetic resin article also has it to utilize problem again.
As utilizing method again, for example can enumerate used synthetic resin article is passed through fusion, make another kind of product molding body again.But, in above-mentioned used synthetic resin article, adhere to a large amount of dusts, and coating material such as coating is also influential, therefore in above-mentioned fused solution, sneak into impurity in a large number.Thereby, goods of Li Yonging again, its weakened is so be only limited to the purposes of using it for no requirement of strength.
On the other hand, slide fastener is a kind of product of frequent open and close type, and especially, the chain closure member needs anti-slide fastener slippery fellow's friction.In addition, also requirement keeps the chimeric of chain toothed portion 13a, 23a and is not easy to come off, and therefore, needs high strength.In addition, under the situation of continuous chain closure member type, when slide fastener is closed, be that crooked shape is carried out the chimeric of the 23a of sprocket portion and separate (Fig. 3 is the inside front view of appearance in the expression slide block) as the 23b of sewing portion in the monofilament of chain closure member, therefore, also need good flexibility.
The present invention proposes in view of above-mentioned condition, and its purpose is, a kind of full intensity that can guarantee is provided, and considers the slide fastener of above-mentioned environmental protection problem.
Slide fastener of the present invention, it mainly comprises: be the chain closure member of raw material with the polyester and be the zipper strip of raw material with the polyester, and be used for the chain closure member is carried out sealed and the slide fastener slippery fellow who separates; At least it is resin that described chain closure member and described zipper strip contain recycled polyester, and described chain closure member also contains new synthetic polyester based resin (hereinafter referred to as former polyester based resin).
As mentioned above, chain closure member special requirement have intensity, but owing in the chain closure member, also contain former polyester based resin, so with only using recycled polyester is that the chain closure member of resin is compared, be good on intensity, therefore, can keep chimeric at the chain toothed portion of chain closure member fully, the friction when can anti-fully slide fastener opening and closing.
In addition, in the present invention, described chain closure member contains the above new synthetic polyester based resin (former polyester based resin) of 20% (quality), is desirable.
If former polyester based resin content is big more, then can seek to improve intensity more, as the chain closure member of slide fastener as previously mentioned by it is contained more than 20% (quality), then can obtain the chimeric retentivity and the wearability of chain toothed portion all excellent, and abundant durable member.If it is its content is more than 30% (quality), then even more ideal.
Have, in of the present invention, the inherent viscosity that constitutes the polymer raw material of described chain closure member is more than 0.67, is desirable again.
Inherent viscosity is good on intensity at the raw material more than 0.67, the therefore abundant anti-slide fastener slippery fellow's of above-mentioned chain closure member friction, and good to the chimeric retentivity of chain toothed portion.
Method as the inherent viscosity (IV) that improves the polymer raw material that constitutes above-mentioned chain closure member can be enumerated: (1) makes and contains a large amount of former polyester based resins; (2) use the high raw material of former polyester based resin inherent viscosity that is contained.The employed former polyester based resin of this (2) method, its inherent viscosity be more than 0.67 (with more than 0.7 for well, better more than 0.75).Also have, the inherent viscosity of general present employed former polyester based resin is 0.6-1.0, by selecting for use in so general former polyester based resin, from the economic point of view, suits.
But, also can consider by to recycled polyester being the method that resin (general 1V 0.6-0.65) carries out the incompatible raising inherent viscosity of solid polycondensation, yet, in such cases, because cost height, so the product of solid phase colour-b value uprises (becoming yellow) like this, firm produced goods color there is harmful effect.
In addition, the inherent viscosity that constitutes the polymer raw material of above-mentioned chain closure member is below 0.90, is desirable.Its reason is because due to the underlying cause, that is, and and when adopting the method for above-mentioned (1), in order to make the polymer raw material inherent viscosity surpass 0.90%, just need contain former polyester based resin (inherent viscosity is higher) in large quantities, do like this, making recycled polyester is that resin content relatively reduces.Lack and reduce the effect that solves environmental problem; Also have, when adopting the method for above-mentioned (2), the former polyester based resin price of high inherent viscosity is very high.Therefore, the inherent viscosity that constitutes the polymer raw material of chain closure member is below 0.85, is even more ideal.
In addition, in the present invention, described chain closure member is the continuous chain closure member that has used monofilament, and the intensity of this monofilament is more than the 4g/d, is desirable.
Like this, if make more than the filament strength 4g/d, friction that then can anti-fully slide fastener slippery fellow, and also retentivity is good, can prevent the comes out of engagement of chain toothed portion.
In addition, in the present invention, 30% (quality) of described zipper strip above for recycled polyester be resin; 10% (quality) of described chain closure member above for recycled polyester be resin; Described slide fastener slippery fellow's 30% (quality) is resin for recycled polyester, and to contain 30% (quality) the above recycled polyester as whole slide fastener be that resin is desirable.
Because containing recycled polyester in a large number is resin, is the consumption of resin so improved recycled polyester, helps to solve or reduce above-mentioned environmental problem.Especially, with regard to above-mentioned zipper strip and above-mentioned slide fastener slippery fellow, from not requiring the intensity as the chain closure member, can make them contain than the more recycled polyester of chain closure member is resin.
Recycled polyester is that resin contains 40% (quality) as a whole for better, contains more than 50% (quality) for better.Also have, with regard to above-mentioned zipper strip, it is above for better that its recycled polyester is that resin contains 40% (quality), and it is above for better to contain 50% (quality).In addition, it is that resin is better that above-mentioned chain closure member contains the above recycled polyester of 20% (quality), and it is above for better to contain 50% (quality).Have, it is that resin is that 40% (quality) is above for better that above-mentioned slide fastener slippery fellow is contained recycled polyester, contains more than 50% (quality) for better again.
Accompanying drawing of the present invention and bis thereof below have been described, and for example, Fig. 1 (a) has the perspective view of the appearance that the front view, (b) of the slide fastener of independent chain closure member install for explanation chain closure member on zipper strip for expression; Fig. 2 has the slide fastener front view of continuous chain closure member for expression; Fig. 3 represents the inside front view of appearance in the slide fastener slippery fellow in the slide fastener with continuous member type chain closure member.In above-mentioned each accompanying drawing, 11, the 21-zipper strip, 11a-thick line, 13,23-chain closure member, 13a, 23a-chain toothed portion, 13b-chain foot section, 22-slide fastener slippery fellow, 23b-sewing portion, 24-sewing thread, the last retainer of 25-, retainer under the 26-.
