Description

本発明は、繊維製品の洗浄に使用する繊維製品洗浄剤に関するものである。 The present invention relates to a textile cleaning agent used for cleaning textiles .

従来、リネンサプライでは被洗物(シーツ・ピロケース等)素材として綿が用いられることが多かったが、近年では被洗物の耐久性(耐洗回数)の優れるポリエステル並びにその混紡布が用いられることが多くなった。   In the past, cotton was often used as the material to be washed (sheets, pillow cases, etc.) in linen supplies, but in recent years polyesters and their blended fabrics that have excellent durability (number of washings) have been used. Increased.

しかし、ポリエステル並びにその混紡布は耐久性に優れるのだが、使用・洗浄を繰り返すことにより汚れが蓄積され、従来の綿素材よりも白度低下が著しい傾向がある。洗浄時に、トリポリリン酸をはじめとする分散剤等やノニオン活性剤を用いても汚れの除去が困難であり、その対策として洗剤量を増やし、強アルカリの過酷な条件で洗浄が行われているが、効果に乏しく単に被洗物の表面を削り取る様な処理がされている。   However, polyester and its blended fabrics are excellent in durability, but stains are accumulated by repeated use and washing, and there is a tendency for whiteness to decrease more significantly than conventional cotton materials. Even when using a dispersant such as tripolyphosphoric acid or a nonionic activator at the time of cleaning, it is difficult to remove the dirt, and as a countermeasure, the amount of detergent is increased and cleaning is performed under severe alkaline conditions. However, the treatment is not effective and the surface is simply scraped off.

木綿等の親水性繊維とポリエステル等の疎水性繊維の双方に効果のある洗浄剤として、特許文献1に、下記式
−NH−R−NH
で表される化合物とNH基と反応する官能基を少なくとも2個有する化合物とを反応させて得られる架橋体からなる汚れ放出剤が開示されている。
As a cleaning agent effective for both hydrophilic fibers such as cotton and hydrophobic fibers such as polyester, Patent Document 1 discloses the following formula R 1 —NH—R 2 —NH.
A soil release agent comprising a cross-linked product obtained by reacting a compound represented by formula (1) with a compound having at least two functional groups that react with NH groups is disclosed.
