Abstract
The present invention is directed to a nonwoven fabric, and specifically to a durable lightweight nonwoven fabric wipe, comprising improved strength, as well as an improved MD to CD elongation ratio, which results in a material imminently suitable for application in the cleaning and cleansing of surfaces. A method of making the nonwoven fabric embodying the present invention includes the steps of providing a precursor web comprising a fibrous matrix. The method further comprises the steps of providing a precursor web, which is subjected to hydroentangling.
Claims2
A method for making a durable lightweight nonwoven imaged wipe in an in-line process at production speeds of at least 150 meters per minute comprising the steps of:
- a. providing a fibrous matrix;
- b. providing a cross-lapper;
- c. providing a foraminous imaging surface;
- d. carding said fibrous matrix into a nonwoven web;
- e. imparting a single transverse fold into said web with said cross-lapper;
- f. pre-hydroentangling said nonwoven web;
- g. advancing said web onto said foraminous imaging surface so as to impart a three-dimensional image or pattern into said web forming said imaged wipe, wherein said imaged wipe has a basis weight less than or equal to 2.0 ounces per square yard and a CD to MD elongation ratio of at least 3:1.
