SPRAY PROCESSES USING A GASEOUS FLOW FOR PREPARING BIODEGRADABLE FIBRILS, NONWOVEN FABRICS COMPRISING BIODEGRADABLE FIBRILS, AND ARTICLES COMPRISING SUCH NONWOVEN FABRICS

摘要

The present invention relates to a process for preparing biodegradable fibrous fibers from one or more biodegradable homopolymer or copolymer resins by a) melting or melting the resin or resins to form a liquid resin mixture, and b) feeding the liquid resin mixture and polyester poly (hydroxybutyrate), poly [(hydroxybutyrate) co (hydroxyvalerate)] or a mixture thereof. The fibrous fibers can be used primarily to make the components of absorbent articles. ŕ
