Development of a Dry Coating Process for Broadloom Carpet. Final Report

摘要

The DASH dry-applied thermoplastic fusion coating process has demonstrated energy savings up to 80%, labor savings up to 50% and coating material cost savings up to 20%. The DASH process generates coatings with characteristics superior to those of latex coatings on most carpets including: better tuft bind, resistance to cleaning agents and moisture, lower applied weights to produce equal or better physical characteristics, and a definitely superior adhesion of the secondary backing. Materials have been obtained, tested and identified as to those which provide the mix formulation ingredients to provide acceptable physical properties. Another area of increasing concern is smoke emission. It is in this area the DASH coating process remains superior. With a mark of 450 and below considered passing and 200 considered to be excellent, the DASH coating has remained well under 100 and has reached as low as 14. (ERA citation 09:016785)
