Title:
COLORED BLEACH-RESISTANT PILE FABRICS AND FLOOR MAT ARTICLES COMPRISING SAID PILE FABRICS
Document Type and Number:
WIPO Patent Application WO2001031115
Kind Code:
A3
Abstract:
This invention relates to new dyeing systems for nylon pile fabrics which are free from chrome-metallized dyestuffs and which comprise at least one cobalt-metallized dyestuff and at least one milling acid dyestuff. Such systems provide highly desirable and effective colorations within target pile fabrics and also provide dramatic improvements in bleach resistance to the nylon fabric surface. The inventive colored pile fabrics are utilized generally as components within launderable floor mat articles which require periodic cleaning with bleach-containing formulations. Thus, the inventive colored fabrics do not exhibit any appreciable reduction in color after such continuous, periodic rigorous cleaning procedures. Floor mats comprised of such inventive colored pile fabrics as well as the particular dyestuff compositions themselves are also encompassed within this invention. Furthermore, methods of coloring pile fabrics with dyestuffs including a heated topical overspray treatment to provide improvements in lightfastness and washfastness are also included.
