Description

本発明は垂直保護網に関し、より詳細には機械的物性が優秀であり、防炎性および日光堅牢度が優秀な効果を同時に発現する垂直保護網に関する。 The present invention relates to a vertical protective net, and more particularly to a vertical protective net which has excellent mechanical properties and simultaneously exhibits excellent effects of flame resistance and sunlight fastness.

建設工事現場では作業者の落下および墜落、各種工具などの落下物が発生するが、このような危険から作業者および市民の安全のために建物の築造時に保護網が設置される。 Workers fall and crash at construction sites, and fallen objects such as various tools occur. Due to such danger, protective nets are installed when the building is built for the safety of workers and citizens.

このような安全事故に備えるためには、保護網の機械的物性が優秀でありながらも防炎性が優秀であり、すべての安全事故が発生し得る地点に設置することができなければならない。 In order to prepare for such a safety accident, the protective net must have excellent mechanical properties and flame resistance, and must be able to be installed at a point where all safety accidents can occur.

また、通常的に建築工事時には垂直保護網は外部に設置されるため直接的または間接的に光を受けざるを得なくなり、優秀な日光堅牢度が要求される。 In addition, since the vertical protection net is usually installed outside during construction work, it has to receive light directly or indirectly, and excellent sunlight fastness is required.

しかし、従来の垂直保護網の場合、所定の機械的物性を発現するとしても防炎性が悪いか、防炎性は優秀であっても日光堅牢度が悪いなど、機械的物性が優秀で防炎性および日光堅牢度が優秀な効果を同時に発現できない問題点があった。 However, in the case of the conventional vertical protective net, the mechanical properties are excellent and the protection is poor, such as poor flame resistance even if the predetermined mechanical properties are exhibited, or excellent flame resistance but poor sunlight fastness. There was a problem that the flame and sunlight fastness could not exhibit excellent effects at the same time.

そこで、機械的物性が優秀であり、防炎性および日光堅牢度が優秀な効果を同時に発現できる垂直保護網に対する開発が急を要しているのが実情である。 Therefore, there is an urgent need to develop a vertical protective net that has excellent mechanical properties and can simultaneously exhibit excellent effects of flame resistance and sunlight fastness.

以下、本発明の垂直保護網１００の各構成について説明する。 Hereinafter, each configuration of the vertical protection net 100 of the present invention will be described.

前記経糸１０は当業界で通常的に使用できる繊維であれば制限なく使うことができ、好ましくはポリエステル系繊維、ポリオレフィン系繊維、ポリアミド系繊維およびアクリレート系繊維などであり得、より好ましくはポリエステル系繊維を使うことができ、さらに好ましくはＰＥＴ繊維を使うことができる。 The warp yarn 10 can be used without limitation as long as it is a fiber that can be normally used in the art, and may be preferably a polyester-based fiber, a polyolefin-based fiber, a polyamide-based fiber, an acrylate-based fiber, or the like, and more preferably a polyester-based fiber. Fiber can be used, and more preferably PET fiber can be used.

一方、前記経糸１０はマルチフィラメントおよびモノフィラメントを混在して使うことができ、好ましくはモノフィラメントを単独で使うことができるが、機械的物性と日光堅牢度の側面でモノフィラメントを単独で使うことがさらに有利であり得る。 On the other hand, the warp 10 can use a mixture of multifilament and monofilament, and preferably monofilament can be used alone, but it is more advantageous to use monofilament alone in terms of mechanical characteristics and sunlight fastness. Can be.

また、前記経糸１０は前記条件（１）および条件（２）を満足するように繊度が２５０～３０００Ｄｅであり得、好ましくは３００～２２００Ｄｅであり得る。万一、前記経糸の繊度が２５０Ｄｅ未満であると垂直保護網の機械的物性および日光堅牢度が低下し得、繊度が３０００Ｄｅを超過すると垂直保護網の防炎性が低下し得る。 Further, the warp 10 may have a fineness of 250 to 3000 De, preferably 300 to 2200 De so as to satisfy the conditions (1) and (2). If the fineness of the warp is less than 250 De, the mechanical properties of the vertical protective net and the fastness to sunlight may decrease, and if the fineness exceeds 3000 De, the flameproof property of the vertical protective net may decrease.

前記緯糸２０は当業界で通常的に使用できる繊維であれば制限なく使うことができ、好ましくはポリエステル系繊維、ポリオレフィン系繊維、ポリアミド系繊維およびアクリレート系繊維などであり得、より好ましくはポリエステル系繊維を使うことができ、さらに好ましくはＰＥＴ繊維を使うことができる。 The weft 20 can be used without limitation as long as it is a fiber that can be normally used in the art, and may be a polyester fiber, a polyolefin fiber, a polyamide fiber, an acrylate fiber, or the like, and more preferably a polyester fiber. Fiber can be used, and more preferably PET fiber can be used.

一方、前記緯糸２０はマルチフィラメントおよびモノフィラメントを混在して使うことができ、好ましくはモノフィラメントを単独で使うことができるが、機械的物性と日光堅牢度の側面でモノフィラメントを単独で使うことがさらに有利であり得る。 On the other hand, the weft 20 can use a mixture of multifilament and monofilament, and preferably monofilament can be used alone, but it is more advantageous to use monofilament alone in terms of mechanical characteristics and sunlight fastness. Can be.

また、前記緯糸２０は前記条件（１）および条件（２）を満足するように繊度が２５０～３０００Ｄｅであり得、好ましくは３００～２２００Ｄｅであり得る。万一、前記経糸の繊度が２５０Ｄｅ未満であると垂直保護網の機械的物性および日光堅牢度が低下し得、繊度が３０００Ｄｅを超過すると垂直保護網の防炎性が低下し得る。 Further, the warp and weft 20 may have a fineness of 250 to 3000 De, preferably 300 to 2200 De so as to satisfy the conditions (1) and (2). If the fineness of the warp is less than 250 De, the mechanical properties of the vertical protective net and the fastness to sunlight may decrease, and if the fineness exceeds 3000 De, the flameproof property of the vertical protective net may decrease.

前記グラウンド糸３０は前述した通り、前記経糸１０および緯糸２０を織り込むように配置され、芯糸および前記芯糸の表面の少なくとも一部を被覆し前記経糸１０、緯糸２０および芯糸より融点が低い被覆部を含む仮融着糸の少なくとも一部が融着されて形成される。 As described above, the ground yarn 30 is arranged so as to weave the warp 10 and the weft 20, covers at least a part of the surface of the core yarn and the core yarn, and has a lower melting point than the warp 10, the weft 20 and the core yarn. At least a part of the temporary fusion yarn including the covering portion is fused and formed.

前記グラウンド糸３０の芯糸および被覆部はそれぞれ独立的に、当業界で通常的に使用できる素材であれば制限なく使うことができ、好ましくはポリエステル系繊維、ポリオレフィン系繊維、ポリアミド系繊維およびアクリレート系繊維などであり得、より好ましくはポリエステル系繊維を使うことができる。 The core yarn and the covering portion of the ground yarn 30 can be independently used without limitation as long as they are materials that can be normally used in the art, preferably polyester fibers, polyolefin fibers, polyamide fibers and acrylates. It may be a system fiber or the like, and more preferably a polyester system fiber can be used.

また、前記被覆部の融点は前記経糸１０、緯糸２０および芯糸より低く、好ましくは１９０℃以下であり得、より好ましくは１８５℃以下であり得る。万一、前記被覆部の融点が１９０℃を超過すると所定の熱処理を通じて仮融着糸の少なくとも一部のみを選択的に融着させることができず、経糸、緯糸および芯糸が先に溶融され得るため機械的物性が低下し得る。 Further, the melting point of the covering portion is lower than that of the warp 10, the weft 20, and the core yarn, preferably 190 ° C. or lower, and more preferably 185 ° C. or lower. If the melting point of the covering portion exceeds 190 ° C., at least a part of the temporarily fused yarn cannot be selectively fused through a predetermined heat treatment, and the warp, weft and core yarn are melted first. Therefore, the mechanical properties may deteriorate.

前記グラウンド糸３０は当業界で通常的に使用できる繊度であれば制限されず、好ましくは繊度が３０～３５０Ｄｅ、より好ましくは繊度が５０～３００Ｄｅであり得る。万一、前記グラウンド糸の繊度が３０Ｄｅ未満であると目的とする水準の機械的物性および日光堅牢度を発現することができず、繊度が３５０Ｄｅを超過すると防炎性が低下し得る。 The ground yarn 30 is not limited as long as it has a fineness that can be normally used in the art, and may preferably have a fineness of 30 to 350 De, and more preferably a fineness of 50 to 300 De. In the unlikely event that the fineness of the ground yarn is less than 30 De, the desired level of mechanical properties and sunlight fastness cannot be exhibited, and if the fineness exceeds 350 De, the flame resistance may decrease.

一方、本発明に係る他の一実施形態によると、前記グラウンド糸は前述した仮融着糸が融着されない状態で備えられてもよいが、これに制限されるものではない。 On the other hand, according to another embodiment of the present invention, the ground yarn may be provided in a state in which the above-mentioned temporary fusion yarn is not fused, but the ground yarn is not limited thereto.

一方、本発明の一実施形態に係る垂直保護網に備えられる経糸、緯糸およびグラウンド糸は、前記経糸および緯糸が相互に織り込まれるように配置され、前記経糸および緯糸を織り込むようにグラウンド糸が備えられ得る。 On the other hand, the warp, weft and ground yarn provided in the vertical protection net according to the embodiment of the present invention are arranged so that the warp and weft are woven into each other, and the ground yarn is provided so as to weave the warp and weft.

前記平織り、綾織りおよび朱子織りを三原組織とする時、三原組織それぞれの具体的な製織方法は通常の製織方法に従い、三原組織を基本としてその組織を変形させたりいくつかの組織を配合して変化がある織物であり得、例えば変化平織りとして畝織、バスケット織 などがあり、変化綾織りとして伸び斜文織、破れ斜文織、非綾織り、山形斜文織などがあり、変化朱子織りとして変則朱子織、重ね朱子織、昼夜朱子織、花崗朱子織などがある。前記二重織は経糸または緯糸のいずれか一方が二重でなっているか両方がすべて二重でなっている織物の製織方法であり、具体的な方法は通常の二重職の製織方法であり得る。ただし、前記織物組織の記載に限定されない。 When the plain weave, twill weave, and satin weave are used as the Mihara structure, the specific weaving method for each of the Mihara structures follows the normal weaving method, and the structure is deformed or some structures are mixed based on the Mihara structure. It can be a woven fabric with changes, for example, there are ridge weaves and basket weaves as change plain weaves, and there are stretch twill weaves, tear twill weaves, non-twill weaves, Yamagata weaves, etc. as change twill weaves. There are irregular satin weaves, twill weaves, day and night satin weaves, and granite satin weaves. The double weaving is a weaving method for a woven fabric in which either one of the warp and the weft is doubled or both are doubled, and the specific method may be a normal double-working weaving method. .. However, the description is not limited to the description of the woven fabric structure.

また、本発明の他の一実施形態に係る垂直保護網に備えられる経糸、緯糸およびグラウンド糸は、前記経糸の上部または下部に緯糸が配置され、前記経糸および緯糸を織り込むようにグラウンド糸が備えられてもよい。 Further, in the warp, weft and ground yarn provided in the vertical protection net according to another embodiment of the present invention, the warp is arranged at the upper or lower part of the warp, and the ground yarn is provided so as to weave the warp and the weft. May be done.
