Description

本発明は、優れたカード通過性を付与し、得られるカードウェブに優れた初期親水性、耐久親水性、及び濡れ戻り防止性を付与するポリオレフィン系合成繊維処理剤及びかかる処理剤が付着したポリオレフィン系合成繊維に関する。   The present invention provides a polyolefin-based synthetic fiber treating agent that imparts excellent card passage properties and imparts excellent initial hydrophilicity, durable hydrophilicity, and anti-wetting property to the resulting card web, and a polyolefin to which such a treating agent is attached. Related to synthetic fiber.

一般に、紙おむつ等の衛生製品として、体液を吸収するために高吸収性高分子の表面にポリオレフィン系の合成繊維で被覆した製品が知られている。高吸収性高分子の表面を被覆する合成繊維は、特に体液をすばやく吸収する初期親水性、繰り返し体液をすばやく吸収する耐久親水性、及び高吸収性高分子に保持された水分の漏れを防止する濡れ戻り防止性が要求される。ポリオレフィン系合成繊維において、上記特性を付与する観点から、ポリオレフィン系合成繊維の表面に界面活性剤等を含有するポリオレフィン系合成繊維処理剤を付与する処理が行われることがある。しかしながら、ポリオレフィン系の合成繊維として、カードローラー(カード機)を使用する乾式法により製造される不織布等が用いられる場合、カード通過性も必要とされる。   In general, as a sanitary product such as a disposable diaper, a product in which the surface of a superabsorbent polymer is coated with a polyolefin-based synthetic fiber to absorb body fluid is known. Synthetic fibers covering the surface of the superabsorbent polymer, especially the initial hydrophilicity that quickly absorbs bodily fluids, durable hydrophilicity that quickly absorbs bodily fluids, and prevents leakage of moisture retained in the superabsorbent polymer Anti-wetting property is required. In the polyolefin synthetic fiber, from the viewpoint of imparting the above characteristics, a treatment for imparting a polyolefin synthetic fiber treating agent containing a surfactant or the like to the surface of the polyolefin synthetic fiber may be performed. However, when a nonwoven fabric or the like manufactured by a dry method using a card roller (card machine) is used as the polyolefin-based synthetic fiber, card passability is also required.

従来、特許文献1に開示されるポリオレフィン系合成繊維処理剤が知られている。特許文献1は、所定のポリオキシアルキレン変性シリコーン及び炭素数28以上の炭化水素基を疎水基とする界面活性剤を含むポリオレフィン系合成繊維処理剤について開示する。   Conventionally, the polyolefin-type synthetic fiber processing agent disclosed by patent document 1 is known. Patent Document 1 discloses a polyolefin-based synthetic fiber treatment agent containing a predetermined polyoxyalkylene-modified silicone and a surfactant having a hydrocarbon group having 28 or more carbon atoms as a hydrophobic group.
