Thesis Title: A study of nonwoven fabric integrity by conventional latex addition versus bicomponent fiber addition
Thesis Author: Rachel Allison Marquardt
Abstract: This thesis investigated and compared latex addition and bicomponent fiber addition as a means of bonding substrate fibers used in molded automotive components, such as trunk liners and deck lids. This objective was accomplished by varying bicomponent fiber type and blend level, latex add-on and oven speed. Specifically, fabrics containing co-polyester, polyethylene-polyester, and polypropylene-polyester sheath/core bicomponent fibers at blend levels of 35 %, 50%, and 65 % were compared to fabrics bonded with 8, 12, and 16 ounces per square yard of latex and dried at low, medium, and high oven speeds. Results show that latex bonded fabrics had higher tensile strength and stiffness than bicomponent fiber fabrics. Bicomponent fiber fabrics had higher elongation, toughness, and bursting strength compared to the latex fabrics.
