Spundbonded fabrics comprising biodegradable polycaprolactone filaments and process for its manufacture

摘要

A spunbonded fabric comprises continuous thermoplastic filaments, which adhere to one another at their intersecting points without binder, and whose material comprises at least 50 weight % biodegradable polycaprolactone having a mean molecular weight of from 35,000 to 70,000. In the production process of the spunbonded fabric, no additional stabilization step is necessary after the filaments are deposited.
