The paper is a report on the progress made in a study designed to establish the influence of several variables on the performance characteristics of nonwoven fabrics. Included among the variables are base fiber properties, binder fiber properties, web formation variables, and bonding variables. Rupture, elastic, and handle properties are being considered as the fabric characteristics. In addition to presenting the variables and responses to be studied, the paper describes the manufacturing process of the nonwovens, which includes open ing and blending, preparation of an air-laid web, and bonding of the thermoplastic binder fiber by means of heat and pressure. The experimental design, which is of a two-level factorial type, is discussed, along with some prelim ary results on the effects of some processing variables. Author
