Description

物と繊維状基材を接触させ、次いで乾燥する工程:を含み、ここで、汚れ反発組成物はフルオロケミカル、シルセスキオキサン含有ゾルおよび潤滑性促進剤:の水性混合物を含んでなる。
本開示をより詳細に説明する前に、本開示が、説明される特定の実施態様に限定されるものではなく、従ってもちろん、変動する可能性があることが理解される。更に、本開示中に使用される用語は特定の実施態様を説明するためのみのものであり、本開示の範囲は添付の請求の範囲によってのみ限定されるので、限定する意図はもたれないことが理解される。
は試験に使用することができるが、好ましい方法および物質を次に説明する。
本明細書で使用される用語「繊維」は、布地および糸並びに織物製造に使用することができる繊維状物質を表す。布地または繊維を製造するためには1種または複数の繊維を使用することができる。糸は当該技術分野で知られる方法に従って完全に延伸するまたは織ることができる。
てを含む構造物を表すことができる。主要裏当ての裏側は糸の返し縫いを覆うための1枚または複数の物質(例えば、コート層、第二の裏当て材、等)を含むことができる。
本開示の実施態様は、汚れ反発組成物、繊維状基材上に汚れ抵抗性を与える方法、汚れ反発組成物が適用され、乾燥された繊維状基材、汚れ反発組成物の製法、等を含む。
)からの繊維状基材に潤滑性促進剤を適用し、そして(d)乾燥する:工程を含む。1つの実施態様において、工程は連続的に実施される。
シルセスキオキサンゾルとともにフルオロケミカルを含む特定の汚れ防止組成物は、特に汚れ抵抗剤のような他の化学薬品も適用されている時には、種々の織物の触感に悪影響を与える可能性がある。特にフッ素化ポリマーおよびシルセスキオキサン含有ゾルを含む汚れ防止処理組成物と同時適用される時には、少量の適当な潤滑性促進剤が、全体の組成物により与えられる汚れ抵抗性を弱めることなく、繊維状基材の滑らかな感触および全体的触感を回復することができることが見いだされた。驚くべきことには、少量の潤滑性促進剤が同様な物質に典型的な投与率に比較されると、最大の利益を与える。更に驚くべきことには、絨毯に適用されると、少量の潤滑性促進成分により与えられる改善された風合いの持続性が、絨毯の摩耗寿命を通して他の基材のものと同様であった。
混合されることができ、そして非イオン物質はアニオン、カチオンまたは非イオンの汚れ防止物質と有効に混合されることができる。これらの一般性にもかかわらず、使用される組成物および種々の界面活性剤および他の成分の他の態様は特定の混合物の適合性および安定性に影響を与える可能性があり、このような考慮はこのような調合技術分野の当業者に周知である。

使用して、2種の極端な例に比較した絨毯物質の触感の質を評価する。パネルによるサンプルの評価および/または順位付けは統計的に評価されて、サンプルの触感および区別可能性(distinguishability)を決定する。
