Abstract

The present invention provides a kind of production technology of anti-arch strap slide fastener, it is characterised in that：It in woven cloth band, by the warp in the tensioning area for belonging to both sides into before weaving station, is pressed in the compression bar for hanging with counterweight on the warp in tensioning area, and the warp in tensioning area is made first to apply tensioning pressure by compression bar into before weaving station, be then woven into strap；The warp of strap be divided into both sides tensioning area and middle part relaxation area, be tensioned area yarn tensile force be more than relaxation area yarn tensile force；Then upper sprocket is combined in the one side for the strap being woven into.The present invention makes the strap of slide fastener not arch upward after being sewn on clothing.

Description

Anti-arch strap slide fastener and its production technology

Technical field

The present invention relates to a kind of slide fastener, specifically a kind of strap has the slide fastener of anti-arch performance.

Background technology

Slide fastener is that a row chain tooth is incorporated on a cloth band to be formed, and strap is made by warp and weft.When slide fastener sews It is that strap is sewed sewing line along warp direction on clothing to through the middle part of strap when on clothing.

When passing through strap due to sewing line, the warp and weft of strap can be squeezed, generate stress, warp is after upper and lower deformation It is distorted, and generates whole strap and rise and fall and gauffer namely strap arch upward phenomenon, influence beauty, it is also possible to cause Slide fastener is engaged problem.

The content of the invention

The present invention provides a kind of anti-arch strap slide fastener and its production technology, the purpose is to solve the disadvantage that the prior art, makes The strap of slide fastener will not arch upward after being sewn on clothing.

The technical solution adopted by the present invention to solve the technical problems is：

A kind of anti-arch strap slide fastener has the strap that warp and weft are woven into, and one side of strap is combined with sprocket, and feature exists In：The warp of strap is divided into the tensioning area of both sides and the relaxation area at middle part, and the tensile force for being tensioned the yarn in area is more than relaxation area The tensile force of yarn.

The warp quantity in the both sides tensioning area of strap occupies the 15%-30% of warp sum respectively.

The quantity of warp is identical occupied by the tensioning area of strap both sides.

A kind of production technology of anti-arch strap slide fastener, it is characterised in that：In woven cloth band, the tensioning area of both sides will be belonged to Warp into before weaving station, be pressed in the compression bar for hanging with counterweight on the warp in tensioning area, and the warp in tensioning area made to exist Tensioning pressure is first applied by compression bar before into braiding station, is then woven into strap；The warp of strap is divided into the tensioning area of both sides With the relaxation area at middle part, be tensioned area yarn tensile force be more than relaxation area yarn tensile force；Then in the cloth being woven into The one side of band combines upper sprocket.

The strap being woven into first in 100 DEG C of -130 DEG C of progress yarn steaming processing, then keeps the temperature 30 minutes, then in the cloth being woven into The one side of band combines upper sprocket.

The balance weight is 10kg-20kg.

The invention has the beneficial effects that：

The intermediate tensile force of strap of the present invention is less than the tensile force of both sides, when strap is sewn on clothing, intermediate warp Line has the space of deformation, so as to avoid the phenomenon that arches upward.

Description of the drawings

The present invention is further described with reference to the accompanying drawings and examples.

Fig. 1 is strap schematic diagram of the present invention；

Fig. 2 is strap machining sketch chart of the present invention.

Specific embodiment

In order to illustrate more clearly of technical scheme, attached drawing needed in description will be made below simple Ground introduction, it should be apparent that, the accompanying drawings in the following description is only some embodiments of the present invention, for ordinary skill For personnel, without creative efforts, other embodiments are can also be obtained according to these attached drawings.

As shown in Figure 1 and Figure 2, in woven cloth band, the warp 2 positioned at both sides is exported from line wheel 3, will be positioned at both sides Warp 2 is first passing through compression bar 5 into before weaving station 7, and 5 lower section of compression bar hangs with counterweight 6, and the weight of the counterweight 6 is 10kg- 20kg, then compression bar 5 push down warp 1, give warp 1 pressing force, make the tensile force of warp 1 increase, and positioned at middle part warp 2 from confession After line wheel 4 exports, pushed down without compression bar and be put into braiding station 7.

In this way, the warp for the strap 100 being such as woven into is divided into the tensioning area 10 of both sides and the relaxation area 20 at middle part, area is tensioned The tensile force of 10 yarn 1 is more than the tensile force of the yarn 2 in relaxation area 20.

The quantity of the yarn 1 in both sides tensioning area 10 is identical, is 10-15 items, and the quantity of the yarn 2 in the relaxation area 20 at middle part exists The quantity of the warp 1 in the both sides tensioning area 10 of 20-50 items namely strap 100 occupies the 15%-30% of warp sum respectively, is left Be middle part relaxation area 20 warp 2.

The strap 100 being woven into first in 100 DEG C of -130 DEG C of progress yarn steaming processing, then keeps the temperature 30 minutes, yarn steaming heat preservation work Skill is to solve the problems, such as that strap 100 reduces.Finally upper sprocket is combined in the one side for the strap 100 being woven into again.

In this way, the strap 100 of slide fastener is sewed when on clothes, when sewing line passes through strap 100, strap 100 can be squeezed Warp and weft generate stress, but the tensile force of the yarn 1 due to being located at both sides tensioning area 10 is more than the relaxation positioned at middle part The tensile force of the yarn 2 in area 20, therefore, the yarn 2 at middle part can be to resistance to stress, and has and be more extruded and become to both sides The leeway of shape, no longer deformation up and down, so as to solve the problems, such as to arch upward.

Each embodiment is described by the way of progressive in this specification, the highlights of each of the examples are with other The difference of embodiment, just to refer each other for identical similar portion between each embodiment.To the upper of the disclosed embodiments It states bright, professional and technical personnel in the field is enable to realize or use the present invention.To a variety of modifications of these embodiments to ability It will be apparent for the professional technician in domain, the general principles defined herein can not depart from the present invention's In the case of spirit or scope, realize in other embodiments.Therefore, the present invention be not intended to be limited to it is shown in this article these Embodiment, and it is to fit to the most wide scope consistent with the principles and novel features disclosed herein.
