Melt blowing technology
Melt blowing technology involves the controlled melting of thermo plastic polymers and subsequent transfer and metered distribution to a multi-orifice nose-piece. Polymer exiting from these orifices
Effects of Polymer Rheology on Meltblowing Fiber formation
The meltblown process is unique, highly engineered, and low-cost nonwoven. This process is unique because it is used almost exclusively to produce microfiber and, recently, nanofibers rather than fiber
Overview of the Fiber Dynamics and Experiment in the Melt Blowing
The evolution of the fiber formation and fibrous web formation models were analyzed. In addition, online and offline experiments used to demonstrate fiber formation and fibrous web
Ultrasonic fortification of interfiber autohesive contacts in meltblown
Thus, the central goal of the present work is to compute the mean work of autohesion of a single fiber–fiber bond in ultrasonically bonded meltblown nonwovens based on the experimentally
An overview of spunbonding and meltblowing technologies
There are three generic types of spinning techniques used in a spunbonding process: melt, dry, and wet. The concept of these tech- niques is directly adapted from con- ventional filament fiber spinning
Investigation of the Fiber, Bulk, and Surface Properties of
The fiber streams will become unstable to a whip-like motion that further elongates them and reduces their diameter. This process continues until a large number of fine polymer filaments (the “splay”) are
(PDF) Effect of Process Parameters on Fiber Diameter and Fiber
As the performance properties of meltblown nonwovens are mainly determined by the fiber diameter and diameter distribution, this study focused on these two characteristics considering
Polymer Melt Spinning for Spunbond and Meltblown Nonwoven
The meltblown process uses the same melt-spinning origin as spunbond, but the fiber formation mechanism is different. Instead of maintaining continuous filaments, meltblown depends on high
Experimental Study of the Airflow Field and Fiber Motion in the Melt
The fiber loop morphology affects the velocity of the fiber movement, causing crossover, folding, and bonding of the moving fiber. The study investigated the interaction between the fiber and
Overview of the Fiber Dynamics during Melt Blowing
Therefore, this work presents a comprehensive overview of the research on fiber dynamics, especially on the evolution of its theories. For the theoretical aspect, the evolution of the
