Description
本発明は、断面が五芒星形のフィラメントを有する織布に関し、さらに詳しくは、洗濯を繰返した後も低空気透過率を維持するための、５つの突出部及び凹部をもつフィラメントを有する織布に関する。 The present invention relates to a woven fabric having a filament with a pentagonal cross section, and more particularly, a woven fabric having a filament having five protrusions and a recess for maintaining a low air permeability even after repeated washing. Regarding cloth.
ダウンジャケットまたはフェイクダウンジャケットのような衣服の表地及び裏地に用いられる織布には、衣服内のダウンまたはフェイクダウンの抜け出しを防止できること及び衣服が空気の出入りに応答してしぼむかまたは膨らむように変形できることを保証するため、低空気透過率を有することが要求される。低空気透過率を達成するための従来の手法は、糸間の隙間を減らすためにフィラメントを圧縮するため、織布の織密度を高めて織布をカレンダー仕上げする方法、例えば特許文献１の方法である。 Woven fabrics used for garments and linings, such as down jackets or faux down jackets, can prevent down or fake down slipping in the garment and allow the garment to squeeze or bulge in response to air in and out. In order to ensure that it can be deformed, it is required to have a low air permeability. A conventional method for achieving a low air permeability is a method of calendering a woven fabric by increasing the woven density of the woven fabric in order to compress the filament in order to reduce a gap between yarns, for example, the method of Patent Document 1 It is.
しかし、織密度を高めてカレンダー仕上げすることによって低空気透過率を制御する方法には、そのようなプロセスを容易に受けることができる能力は断糸が頻繁におこり得るから信頼できない、及び織速度が比較的低いから生産性が最低限にとどまるという、基本的問題がある。さらに、得られた織布が初期状態では低空気透過率を有していても、折畳み、洗濯、等をともなう日常の使用における曲げ及び膨張／収縮のような力により、時間が経過する間に糸間の隙間が拡がるから、初期低空気透過率を維持することは非常に困難である。したがって、ダウンまたはフェイクダウンは散逸してしまいそうである。 However, the method of controlling low air permeability by increasing the weave density and calendering is unreliable because the ability to easily undergo such a process can occur frequently and the weaving speed There is a fundamental problem that productivity is kept to a minimum because of relatively low. In addition, even though the resulting woven fabric has low air permeability in the initial state, the force of bending and expansion / contraction in daily use with folding, washing, etc. Since the gap between the yarns is widened, it is very difficult to maintain the initial low air permeability. Thus, the down or fake down is likely to dissipate.
本開示の一態様は、繰返し洗濯した後も低空気透過率を維持するための、断面が五芒星形のフィラメントを有する織布を提供する。 One aspect of the present disclosure provides a woven fabric having a pentagonal cross-section filament to maintain low air permeability after repeated laundering.
本開示のこの態様にしたがえば、複数本のフィラメントが撚り合わされた糸（マルチフィラメント糸）を複数本有し、マルチフィラメント糸の内の少なくとも１本は断面が五芒星形の第１及び第２のフィラメントを有し、第１及び第２のフィラメントは１.４と２.６の間の非円度を有し、織布は、マルチフィラメント糸の少なくとも一部が圧縮され、第１及び第２のフィラメントが相互に噛み合うようにカレンダー仕上げされた少なくとも１つの表面を有する。 According to this aspect of the present disclosure, a plurality of yarns (multifilament yarns) in which a plurality of filaments are twisted together are provided, and at least one of the multifilament yarns is a first and a pentagonal cross section. A second filament, the first and second filaments have a non-circularity between 1.4 and 2.6, and the woven fabric is compressed with at least a portion of the multifilament yarn, And at least one surface calendered so that the second filaments mesh with each other.
第１のフィラメントの第１のフィラメントに隣接する第２のフィラメントとの噛合い構造により、織布のマルチフィラメント糸は、繰返し洗濯した後でさえ織布の空気透過率が非常に低いレベルに維持されるように、堅固に結合される。 Due to the interlocking structure of the first filament with the second filament adjacent to the first filament, the multifilament yarn of the woven fabric maintains the air permeability of the woven fabric at a very low level even after repeated washing. As tightly as possible.

図４は、本開示の一実施形態にしたがう、図１の織布１０のマルチフィラメント糸の１本の略図である。本発明の一実施形態において、マルチフィラメント糸は，第１の層の複数本のフィラメント１Ａ〜１Ｇ，第１の層の上の第２の層の複数本のフィラメント２Ａ〜２Ｆ及び第２の層の上の第３の層の複数本のフィラメント３Ａ〜３Ｃを含む。図４を参照すれば、本開示の一実施形態において、マルチフィラメント糸はフィラメント２Ｂに隣接する３本のフィラメント１Ｂ，２Ａ，３Ａを有し、３本のフィラメント１Ｂ，２Ａ，３Ａはフィラメント２Ｂと噛み合う。またマルチフィラメント糸はフィラメント２Ｄに隣接する４本のフィラメント１Ｄ，２Ｃ，２Ｅ，３Ｃを有し、４本のフィラメント１Ｄ，２Ｃ，２Ｅ，３Ｃはフィラメント２Ｄと噛み合う。 FIG. 4 is a schematic illustration of one multifilament yarn of the woven fabric 10 of FIG. 1 according to one embodiment of the present disclosure. In one embodiment of the present invention, the multifilament yarn includes a plurality of filaments 1A to 1G in the first layer, a plurality of filaments 2A to 2F in the second layer above the first layer, and a second layer. A plurality of filaments 3A-3C in a third layer on the substrate. Referring to FIG. 4, in one embodiment of the present disclosure, the multifilament yarn has three filaments 1B, 2A, and 3A adjacent to the filament 2B, and the three filaments 1B, 2A, and 3A are the filament 2B and the filament 2B. Engage. The multifilament yarn has four filaments 1D, 2C, 2E, 3C adjacent to the filament 2D, and the four filaments 1D, 2C, 2E, 3C mesh with the filament 2D.
本発明の好ましい実施形態において、五芒星形フィラメントの動きは少なくとも１本の横方向に隣接するフィラメント及び１本の縦方向に隣接するフィラメントによって制限される。例えば、フィラメント１Ｃは横方向にフィラメント１Ｂに隣接し、縦方向にフィラメント２Ｃに隣接していて、フィラメント１Ｃの５つの突出部の内の１つがフィラメント１Ｂの２つの突出部の間に押し込まれ、フィラメント１Ｃの５つの突出部の内の別の１つがフィラメント２Ｃの突出部の内の２つの間に押し込まれる。さらに、フィラメント１Ｃの５つの突出部の内の１つがフィラメント１Ｄの突出部の内の２つの間に押し込まれ、フィラメント１Ｄの５つの突出部の内の１つがフィラメント１Ｃの突出部の内の２つの間に押し込まれる。 In a preferred embodiment of the invention, the movement of the pentagonal filament is limited by at least one laterally adjacent filament and one longitudinally adjacent filament. For example, the filament 1C is adjacent to the filament 1B in the transverse direction and adjacent to the filament 2C in the longitudinal direction, and one of the five protrusions of the filament 1C is pushed between the two protrusions of the filament 1B, Another one of the five protrusions of the filament 1C is pushed between two of the protrusions of the filament 2C. Furthermore, one of the five protrusions of the filament 1C is pushed between two of the protrusions of the filament 1D, and one of the five protrusions of the filament 1D is two of the protrusions of the filament 1C. Pushed into one.
２本の横方向に隣接するフィラメント１Ｂ及び１Ｃに対し、隣接するフィラメント１Ｂの２つの突出部の間へのフィラメント１Ｃの突出部の押込みは、フィラメント１Ｃの縦方向の動きを制限するだけでなく、横方向の動きも制限する。同様に、２本の縦方向に隣接するフィラメント１Ｃ及び２Ｃに対し、隣接するフィラメント２Ｃの２つの突出部の間へのフィラメント１Ｃの突出部の押込みは、フィラメント１Ｃの縦方向の動きを制限するだけでなく、横方向の動きも制限する。したがって、マルチフィラメント糸内の五芒星形フィラメントの動きが制限される。隣接するフィラメントの突出部の内の３つの間に押し込まれる少なくとも３つの突出部をフィラメントが有していれば、マルチフィラメント糸内の五芒星形フィラメントの動きはさらに制限される。 For the two laterally adjacent filaments 1B and 1C, the pushing of the protrusion of the filament 1C between the two protrusions of the adjacent filament 1B not only restricts the longitudinal movement of the filament 1C Also restrict lateral movement. Similarly, for the two longitudinally adjacent filaments 1C and 2C, the pushing of the protruding portion of the filament 1C between the two protruding portions of the adjacent filament 2C limits the longitudinal movement of the filament 1C. As well as restricting lateral movement. Therefore, the movement of the pentagram filament in the multifilament yarn is limited. If the filament has at least three protrusions that are pushed between three of the adjacent filament protrusions, the movement of the pentagram filaments in the multifilament yarn is further limited.
図５は、本開示の一実施形態にしたがう、カレンダー仕上処理後の織布１０のマルチフィラメント糸を示すＳＥＭ（走査型電子顕微鏡）像であり、図６は、本開示の一実施形態にしたがう、５０回洗濯した後のカレンダー仕上織布１０のマルチフィラメント糸を示すＳＥＭ像である。織上げ後の織布は一般に、薄地織布を作製するために一般に用いられる処理装置を用いることで、精練され、緩和され、プリセットされ、染色されて、仕上処理にかけられる。本発明の一実施形態において、織布１０は、マルチフィラメント糸の少なくとも一部が圧縮されて、フィラメントが相互に噛み合うように、カレンダー仕上げされた少なくとも１つの表面を有する。 FIG. 5 is an SEM (Scanning Electron Microscope) image showing multifilament yarns of the woven fabric 10 after calendar finishing according to one embodiment of the present disclosure, and FIG. 6 is according to one embodiment of the present disclosure. FIG. 5 is an SEM image showing a multifilament yarn of the calendered woven fabric 10 after washing 50 times. The woven fabric after weaving is generally scoured, relaxed, preset, dyed and subjected to a finishing treatment by using a processing apparatus generally used for producing a thin woven fabric. In one embodiment of the present invention, the woven fabric 10 has at least one surface that is calendered so that at least a portion of the multifilament yarn is compressed and the filaments engage each other.
織布をカレンダー仕上げにかけることで、マルチフィラメント糸の五芒星形フィラメントは圧縮され、マルチフィラメント糸の少なくとも一部において五芒星形フィラメントが相互に重なり合う状態に固定される。本発明の一実施形態において、カレンダー仕上げの温度に特に制限はないが、五芒星形フィラメントの作製に用いられる原材料のガラス転移温度より高く、原材料の融点よりは低いことが好ましい。 By subjecting the woven fabric to calendering, the pentagonal filaments of the multifilament yarn are compressed, and the pentagonal filaments are fixed to overlap each other in at least a part of the multifilament yarn. In one embodiment of the present invention, the calendering temperature is not particularly limited, but it is preferably higher than the glass transition temperature of the raw material used for producing the pentagonal filament and lower than the melting point of the raw material.
カレンダー仕上げの圧力は、織布の上側の五芒星形フィラメントの凸面が実質的に平坦になるように設計される。本開示の一実施形態において、織布のカレンダー仕上処理は２本一組のロールを用いることで実施することができる。カレンダー仕上処理後、織布１０のマルチフィラメント糸は、洗濯を繰り返した後でも織布１０の空気透過率が非常に低いように、堅固に結合される。 The calendering pressure is designed so that the convex surface of the pentagram filament on the upper side of the fabric is substantially flat. In one embodiment of the present disclosure, the calender finishing process of the woven fabric can be performed by using a set of two rolls. After the calender finishing process, the multifilament yarn of the woven fabric 10 is firmly bonded so that the air permeability of the woven fabric 10 is very low even after repeated washing.
本開示においては、本発明にしたがう図５〜６に示される例証織布及び図７〜１０に示される対照織布の空気透過率を客観的に評価するため、ＪＩＳ１０９６-８.２６.１Ａに指定される空気透過率試験方法を用いた。例証織布及び対照織布の試験結果を下表にまとめてある。
表に明確に示されるように、例証織布及び対照織布の初期空気透過率は実質的に同じレベルにある。しかし、５０回洗濯した後、対照織布の空気透過率は劇的に増加し、Ｙ字形フィラメントについては２倍になり、扁平フィラメントについては５倍になるが、例証織布の空気透過率は初期空気透過率と実質的に同じレベルに維持される。明らかに、織布のマルチフィラメント糸はフィラメントの五芒星形断面により堅固に結合され、よって洗濯を繰り返した後でも織布の空気透過率は非常に低いレベルに維持される。 As clearly shown in the table, the initial air permeability of the exemplary and control fabrics is at substantially the same level. However, after 50 washes, the air permeability of the control fabric increases dramatically, doubles for the Y-shaped filaments and 5 times for the flat filaments, but the air permeability of the illustrated fabric is It is maintained at substantially the same level as the initial air permeability. Obviously, the multifilament yarn of the woven fabric is tightly bound by the pentagonal cross section of the filament, so that the air permeability of the woven fabric is maintained at a very low level even after repeated washing.
