Description

仮撚加工機用ヒーター塗布剤Heater coating agent for false twisting machine
　本発明は、仮撚加工機において糸がヒーターから外れることを抑制することを目的として、ヒーターに塗布する仮撚加工機用ヒーター塗布剤に関する。 The present invention relates to a heater coating agent for a false twisting machine to be applied to a heater for the purpose of suppressing the yarn from coming off the heater in the false twisting machine.
　近年、衣類の多様化、ファッション化の傾向は益々進行し、中でも、適度の伸縮性や嵩高さがあり、良好な風合いにより身体に気持ちよくフィットするスポーツ用衣類や婦人用ファンデーション衣類など機能性ウェアに対する要望が高くなっている。この機能性ウェアの製造には、仮撚加工糸は不可欠なものである。
　一般に、仮撚加工糸（Ｄｒａｗ　Ｔｅｘｔｕｒｅｄ　Ｙａｒｎ；以下、ＤＴＹということがある。）は、合成繊維用処理剤を付与して部分延伸糸（Ｐａｒｔｉａｌｌｙ　Ｏｒｉｅｎｔｅｄ　Ｙａｒｎ；以下、ＰＯＹということがある。）である合成繊維フィラメント糸条を生産した後、仮撚装置の加熱装置（ヒーター）により合成繊維フィラメント糸条を加熱し、同時にフィラメント糸条に撚りを与えながら延伸することにより得られる。部分延伸糸（ＰＯＹ）に付与される合成繊維用処理剤は、特に乳化剤や制電剤等に工夫がなされ、ヒーター汚れ、毛羽糸切れ、静電気発生を抑制する設計がなされてきた（例えば、特許文献１、２等）。
　しかしながら、このような合成繊維用処理剤が付与された部分延伸糸（ＰＯＹ）でも、加熱装置（ヒーター）から合成繊維フィラメント糸条が外れる又はズレてしまい、毛羽糸切れが発生するほか、加熱不足及び糸道のズレにより十分な撚りや延伸が出来ないといった問題があった。 In recent years, the diversification and fashion trend of clothing has been increasing, and in particular, for functional clothing such as sports clothing and women's foundation clothing, which have moderate elasticity and bulkiness and fit comfortably to the body with a good texture. The demand is high. False twisted yarn is indispensable for the production of this functional wear.
In general, a false twisted yarn (Draw Textured Yarn; hereinafter, may be referred to as DTY) is a partially drawn yarn (hereinafter, may be referred to as POY) to which a treatment agent for synthetic fibers is applied. It is obtained by producing synthetic fiber filament yarns, heating the synthetic fiber filament yarns with a heating device (heater) of a false twisting device, and at the same time stretching the filament yarns while twisting them. The synthetic fiber treatment agent applied to the partially drawn yarn (POY) has been specially devised such as an emulsifier and an antistatic agent, and has been designed to suppress heater stains, fluff breakage, and static electricity generation (for example, patent). Documents 1, 2 etc.).
However, even in the partially drawn yarn (POY) to which such a treatment agent for synthetic fibers is applied, the synthetic fiber filament yarns come off or shift from the heating device (heater), causing fluff breakage and insufficient heating. In addition, there is a problem that sufficient twisting and stretching cannot be performed due to misalignment of the yarn path.

　表２に示すとおり、本発明の仮撚加工機用ヒーター塗布剤の具体例である実施例１～１９は、仮撚加工機において合成繊維フィラメント糸条がヒーターから外れる「糸外れ」を良好に抑制することが、さらに、「糸外れ」による毛羽糸切れや合成繊維フィラメント糸条の加熱不足を防止して、良好に撚り延伸された仮撚加工糸が得られることも確認された。
　また、実施例１～１９の仮撚加工機用ヒーター塗布剤は、短時間で仮撚加工機のヒーター上に拡がる拡展性にも優れていることも、明らかとなった。
　これに対して、本発明の仮撚加工機用ヒーター塗布剤を仮撚加工機のヒーターに塗布せず、合成繊維用処理剤を付着した部分延伸糸（ＰＯＹ）を用いた場合には、「糸外れ」を抑制することが出来ず、「糸外れ」による毛羽糸切れが発生することも明らかとなった。 As shown in Table 2, Examples 1 to 19, which are specific examples of the heater coating agent for the false twisting machine of the present invention, satisfactorily prevent the synthetic fiber filament yarn from coming off the heater in the false twisting machine. It was also confirmed that the suppression further prevented fluff yarn breakage due to "thread detachment" and insufficient heating of the synthetic fiber filament yarn, and that a well-twisted and stretched false twisted yarn could be obtained.
It was also clarified that the heater coating agents for the false twisting machine of Examples 1 to 19 are also excellent in malleability that spreads on the heater of the false twisting machine in a short time.
On the other hand, when the heater coating agent for the false twisting machine of the present invention is not applied to the heater of the false twisting machine and the partially drawn yarn (POY) to which the processing agent for synthetic fibers is attached is used, ". It was also clarified that the "thread detachment" could not be suppressed and the fluff thread breakage due to the "thread detachment" occurred.
　本発明の仮撚加工機用ヒーター塗布剤や、この仮撚加工機用ヒーター塗布剤を仮撚加工機のヒーターに塗布する仮撚加工糸の製造方法は、仮撚加工機において合成繊維フィラメント糸条がヒーターから外れる「糸外れ」を抑制し、「糸外れ」による毛羽糸切れや合成繊維フィラメント糸条の加熱不足を防止して、良好に撚り延伸された仮撚加工糸が得られるため非常に有用である。 The method for producing the false twisting machine heater coating agent of the present invention and the false twisting yarn for applying the false twisting machine heater coating agent to the false twisting machine heater is a synthetic fiber filament yarn in the false twisting machine. It suppresses "thread detachment" in which the strands come off from the heater, prevents fluff yarn breakage due to "thread detachment" and insufficient heating of synthetic fiber filament yarns, and is extremely twisted and stretched because false twisted yarns can be obtained. It is useful for.
