Description

より具体的には、上記課題は、芯成分と鞘成分の重量比が20/80〜80/20である偏芯芯鞘型複合繊維であって、鞘成分が熱可塑性ポリエステルエーテルを含み、繊度が1.0〜50.0dtex、繊維長が3〜30mm、捲縮数が1.0〜20.0山/25mm、捲縮率が50〜80%の機械捲縮を有し、100℃以上の熱処理で3次元捲縮またはΩ型捲縮を発現することを特徴とするエアレイド不織布用繊維によって解決することができる。更に、120℃乾熱処理後の捲縮率が90%以上であること、更にエアレイド不織布用繊維の表面に油剤が付与されており、該油剤として、ジメチルシロキサン、ポリオキシアルキレン変性ジメチルシロキサン、または、アミド変性ジメチルシロキサンを0.15〜0.50質量%エアレイド不織布用繊維表面に付与していることが好ましく採用することができる。このような構成を採用する事で、開繊性向上によるスクリーンの通過が良くなり、クッション性、柔軟性、弾性回復性に優れたエアレイド不織布によっても上記発明の課題を解決することができる。 More specifically, the above-mentioned problem is an eccentric core-sheath type composite fiber in which the weight ratio of the core component to the sheath component is 20/80 to 80/20, wherein the sheath component contains a thermoplastic polyester ether, and the fineness Has a mechanical crimp of 1.0 to 50.0 dtex, fiber length of 3 to 30 mm, crimp number of 1.0 to 20.0 mountain / 25 mm, crimp rate of 50 to 80%, 100 ° C. or more This can be solved by an airlaid nonwoven fabric characterized in that a three-dimensional crimp or an Ω-type crimp is expressed by the heat treatment. Furthermore, the crimp ratio after 120 ° C. dry heat treatment is 90% or more, and further, an oil agent is applied to the surface of the airlaid nonwoven fabric fiber. As the oil agent, dimethylsiloxane, polyoxyalkylene-modified dimethylsiloxane, or It is preferable to apply the amide-modified dimethylsiloxane to the surface of the fiber for air-laid nonwoven fabric in an amount of 0.15 to 0.50% by mass . By adopting such a configuration, the passage of the screen is improved by improving the spreadability, and the problem of the invention can be solved even by an airlaid nonwoven fabric excellent in cushioning property, flexibility and elastic recovery property.

複合繊維には油剤が付与されていることが好ましく、その付与する油剤として、ジメチルシロキサン、ポリオキシアルキレン変性ジメチルシロキサン、または、アミド変性ジメチルシロキサンを0.15〜0.50質量%エアレイド不織布用繊維の表面に付与していることが好ましい。0.15重量%未満ではエアレイド開繊工程において静電が発生しやすく、毛玉等を起こしてしまう。また、0.50重量%を超える場合では油剤による繊維同士の接着性が上がり開繊不良を起こしてしまう。より好ましくはポリオキシアルキレン変性ジメチルシロキサンを用いることである。また油剤付与量としては0.16〜0.30重量%であることがより好ましい。 The composite fiber is preferably provided with an oil agent. As the oil agent to be provided, 0.15 to 0.50% by mass of an airlaid nonwoven fabric containing dimethylsiloxane, polyoxyalkylene-modified dimethylsiloxane, or amide-modified dimethylsiloxane. It is preferable that it is provided on the surface. If it is less than 0.15% by weight, static electricity is likely to be generated in the airlaid opening process, which causes pills and the like. Moreover, when it exceeds 0.50 weight%, the adhesiveness of the fibers by an oil agent will rise, and it will cause a fiber opening defect. More preferably, polyoxyalkylene-modified dimethylsiloxane is used. Moreover, it is more preferable that it is 0.16-0.30 weight% as an oil agent provision amount.
