Abstract: In recent years, spunlaid technology and related products have made great progress. For example, meltblown nanofiber technology has become a research hotspot; directly-formed cellulose webs have achieved commercial production; spunblown products have entered the PPE market; the new two-component spunbond filter media has been used to protect against the new coronavirus. The paper introduces the new progress of the spunlaid technology and the application of its products in the field of medical, and looks forward to the future trend.

Key words: submicron-nano fiber; split spinning; meltblown; direct web form; filter media
