さらに詳しくは多層構造の経編地であって、内層部に導
電性繊維糸条を、外層部には通常の非導電性繊維糸条を
存在させた、外観の美しい編地に関する考案である。More specifically, it is a warp-knitted fabric with a multilayer structure, which has conductive fiber threads in the inner layer and normal non-conductive fiber threads in the outer layer, and which has a beautiful appearance.
脅威繊維、天然繊維はともに摩擦により帯電することは
周知である。It is well known that both menacing fibers and natural fibers become electrically charged due to friction.
特に脅威繊維の摩擦帯電は顕著であり、冬期乾燥時、衣
服が身体にまとわりついたり、放電による火花が発生し
たり、またひどいときには火花放電によるショックを受
けたりして不快感を受けることがある。Frictional electrification of threat fibers is particularly noticeable, and when dry in winter, clothing may cling to the body, sparks may be generated due to electrical discharge, and in severe cases, the user may receive a shock from the spark discharge, causing discomfort.
さらには塵埃を吸着して汚れやすくなったり、あるいは
発火による爆発等を招いたりして危険なこともある。Furthermore, it can become dangerous because it attracts dust and becomes dirty easily, or it can cause an explosion due to ignition.

のとして炭素繊維を用いることにより制電効果を与えて
いた。In order to improve this problem, conventional methods have been to attach an antistatic agent to the fabric to give it an antistatic effect, or to make carbon-based fine particles or other conductive components exist in the polymer that makes up the filament yarn. Alternatively, an antistatic effect was provided by using carbon fiber as the filament yarn.
しかしながら前記帯電防止剤の付着による方法は、耐洗
濯性に劣り耐久性が満足されず、炭素成分を用いたフィ
ラメント糸条の方法では黒色あるいはこれに近い灰色の
ものとなるため、例えば白を基調とする衣料製品は得る
ことができず。However, the method of attaching an antistatic agent has poor washing resistance and unsatisfactory durability, and the method of filament yarn using a carbon component results in black or a gray color close to this, so for example, the color is based on white. And the clothing products can't be obtained.
製品展開上制約があった。There were restrictions on product development.
そこで、編物の場合でも黒あるいは灰色の該制電性繊維
を内層部に入れる方式が試みられているが未だ被覆性の
よい編物は得られていない。Therefore, even in the case of knitted fabrics, attempts have been made to incorporate black or gray antistatic fibers into the inner layer, but a knitted fabric with good coverage has not yet been obtained.
本考案は従来のかかる欠、魚を改善せんとするもので、
制電性能を十分に発揮し、かつ導電性繊維糸条の有する

たは全体的に均一に分散せしめた制電タイプの金属繊維
フィラメントまたは紡績糸等をいう。For example, carbon black is applied to metal fibers such as stainless steel fibers, aluminum fibers, copper, silver, and gold, as well as carbon chain bonded fibers such as carbon fibers, flame-resistant fibers, and graphite fibers, and metal fibers such as nylon, polyester, acrylic, and polyolefin. Refers to an antistatic type metal fiber filament or spun yarn in which fine particles are uniformly dispersed partially or completely as viewed from the cross-sectional direction of the fiber.

次に本考案においては、導電性繊維は３層以上の多層構
造経編地の内層に存在していることが必要である。Next, in the present invention, it is necessary that the conductive fibers be present in the inner layer of the multilayered warp knitted fabric having three or more layers.
非導電性繊維糸条によって被覆させてしまうためである
。This is because it is covered with non-conductive fiber threads.
次に本考案の編地においては、導電性繊維糸条は、非導
電性繊維糸条が形成するニードルループに沿って、同一
ウエール内で１コース毎に交互に左右ジグザグ状に存在
しなければならない。Next, in the knitted fabric of the present invention, the conductive fiber threads must be present in a left and right zigzag pattern alternately for each course within the same wale along the needle loops formed by the non-conductive fiber threads. It won't happen.
すなわち導電性繊維糸条は編地の構造材料として形態を
作るため、あるいは編地強度を向上するために存在させ
るのではなく、単に表地と裏地との間に配列させるだけ
に用いるのである。In other words, the conductive fiber threads are not present as a structural material of the knitted fabric to create its shape or to improve the strength of the knitted fabric, but are simply used to arrange it between the outer fabric and the lining fabric.
また外部から見えなくするように配列させる必要がある
。It is also necessary to arrange them so that they are not visible from the outside.
このために他糸条のニードルループに沿って同一ウエー
ル内で１コース毎に左右ジグザグ状に配列させることが
必要となる。For this reason, it is necessary to arrange the yarns in a left-right zigzag pattern for each course within the same wale along the needle loops of other yarns.
以上を図面を用いて説明する。The above will be explained using the drawings.
第１図〜第４図は３枚筬の経編機により本考案を説明す
るための編組織の一例を示す。1 to 4 show an example of a knitting structure for explaining the present invention using a three-reed warp knitting machine.
この図は２枚筬によるハーフ組織に中筬１枚を追加して
数ウエール毎に導電性繊維糸条をインレイ方式で直線状
に縦走させた編地を示している。This figure shows a knitted fabric in which one inner reed is added to the half structure of two reeds, and conductive fiber threads are run longitudinally in a straight line every few wales using an inlay method.
すなわち糸条ａは通常の非導電性繊維糸条からなり、前
筬の全てのガイドに通し、チェン組織は１−０／２−３
として導糸させ、第１図の組織図のように編成される。In other words, yarn a is made of a normal non-conductive fiber yarn and is passed through all the guides of the front reed, and the chain structure is 1-0/2-3.
The yarn is introduced as shown in FIG. 1 and knitted as shown in the organization chart in FIG.
糸条すは導電性繊維糸条からなり中筬ガイドヘ一定の間
隔をおいて通し、０−０７１−１、または１−１１０−
０のチェン組織のもとに導糸させ、第２図のように編目
を作らずに編込まれる。The threads are made of conductive fiber threads, passed through the inner reed guide at regular intervals, and are 0-071-1 or 1-110-
The yarn is guided under the chain structure of 0, and knitted without making any stitches as shown in Fig. 2.
また糸条Ｃは非導電性繊維糸条からなり、後筬の全ての
ガイドに通し、チェン組織は１−０／１−２として導糸
させ、第３図のように編成されたものである。The thread C is made of a non-conductive fiber thread and is threaded through all the guides of the rear reed, with a chain structure of 1-0/1-2, and is knitted as shown in Figure 3. .
その結果、導電性繊維糸条すは、糸条ａと糸条Ｃの間に
挾まれて隠れるため、編地の表面あるいは裏面から見え
なくなり、本考案の目的が達せられるのである。As a result, the conductive fiber threads are sandwiched and hidden between threads a and threads C, so that they are no longer visible from the front or back side of the knitted fabric, thereby achieving the purpose of the present invention.
次に本考案においては、導電性繊維糸条の糸長は編地に
対して１．１〜１．８倍長いことが必要である。Next, in the present invention, the yarn length of the conductive fiber yarn needs to be 1.1 to 1.8 times longer than the knitted fabric.
このことは、編地を一定長採り、導電性繊維を引き抜く
か、または編地を分解して導電性繊維を取り出して真直
に延ばしたときに、前記の編地の長さに対し、導電性繊
維糸条の方がｉ、ｉ〜１．８倍長いことを意味する。This means that when a certain length of knitted fabric is taken and the conductive fibers are pulled out, or when the knitted fabric is taken apart and the conductive fibers are taken out and stretched straight, the conductive It means that the fiber thread is i, i~1.8 times longer.
好ましい長さ倍率は１．３〜１．５＠である。The preferred length magnification is 1.3 to 1.5@.
導電性繊維糸条をニードルループの１つ１つに沿わせて
外部から見えなくするためである。This is to make the conductive fiber yarn along each needle loop so that it is not visible from the outside.
導電性繊維糸条の長さ倍率が１．８倍を越える範囲では
導電性繊維糸条がａ糸条、Ｃ糸条の編目に完全に抱き込
まれず、編地表面から見え易くなる。In a range where the length magnification of the conductive fiber yarn exceeds 1.8 times, the conductive fiber yarn is not completely wrapped in the stitches of the A yarn and C yarn, and becomes easily visible from the surface of the knitted fabric.
極端に編込率が大きすぎる場合は編地表面に導電性繊維
糸条が飛び出す恐れもある。If the knitting ratio is extremely high, there is a risk that conductive fiber threads will pop out on the surface of the knitted fabric.
また逆に長さ倍率が１．１倍未満では編地に吊りが起こ
り好ましくない。Conversely, if the length magnification is less than 1.1 times, the knitted fabric will hang, which is undesirable.
なお、ここでいう長さ倍率の測定は仕上加工後の生地に
対する編地長さと編込糸長の比率である。Note that the measurement of the length magnification here is the ratio of the length of the knitted fabric to the length of the knitted yarn with respect to the fabric after finishing processing.
一般に編地長さおよび編込まれた糸長は染色仕上加工段
階で受けるさまざまな緊張と熱処理効果によって変化す
る。In general, the length of the knitted fabric and the length of the knitted yarns vary depending on the various tensions and heat treatment effects experienced during the dyeing and finishing process.
このため生機設計における編込糸長は地糸と導電性繊維
糸条の熱収縮率差や編地の仕上加工方法なども考慮して
決める必要がある。For this reason, the length of the knitting yarn in the gray fabric design must be determined by taking into account the difference in heat shrinkage rate between the base yarn and the conductive fiber yarn, the finishing method of the knitted fabric, etc.
次に導電性繊維糸条を導く中筬の動きについては、オー
バラップは行なわず（インレイ）、アンダラッピング時
だけ１コース毎にジグザグに１針間移動させることが必
要である。Next, regarding the movement of the inner reed that guides the conductive fiber yarn, it is necessary to move it by one stitch in a zigzag manner for each course only during underlapping, without overlapping (inlay).
すなわち、チェン組織は０−０／１−１または１−１１
０−０とナル。That is, the Chen organization is 0-0/1-1 or 1-11
0-0 and Naru.
オーバラッピングにより編目ループを作ルと、表と裏糸
の間から導電性繊維糸条のループが見え易くなりよくな
い。If a stitch loop is created by overlapping, the loop of the conductive fiber yarn becomes easily visible between the front and back yarns, which is not good.
またアンダーラッピングが大きい場合、すなわち筬の振
り幅を大きくすると導電性繊維糸条が横方向に筏状に見
えるため不適当である。Furthermore, if the underlapping is large, that is, if the swing width of the reed is increased, the conductive fiber threads will appear raft-like in the lateral direction, which is inappropriate.
さらにアンダーラッピングは１コース毎にジグザグにな
るよう筬を左右に振らないと導電性繊維糸条が縦方向に
筋状に見えるためよくない。Furthermore, underwrapping is not good because unless the reed is shaken from side to side in a zigzag pattern for each course, the conductive fiber threads will appear vertically streaky.
このように導電性繊維糸条の筬の動きと編込糸長を規制
することによって、導電性繊維糸条を完全に表地と裏地
で被覆することができ、本考案の目的を達成することが
できる。By regulating the movement of the reed of the conductive fiber yarn and the length of the knitting yarn in this way, the conductive fiber yarn can be completely covered with the outer material and the lining material, and the purpose of the present invention can be achieved. can.
また本考案においては導電性繊維をカバーリングするこ
となく裸で使うことができるので、目付の薄い経編地と
することも可能である。Furthermore, in the present invention, since the conductive fibers can be used bare without covering, it is also possible to create a warp-knitted fabric with a thin basis weight.
次に実施例を用いて説明する。Next, an explanation will be given using an example.
