Nonwoven fabric Last updated January 13 2020 Non-woven fabric is a fabric-like material made from staple fibre (short) and long fibres (continuous long) bonded together by chemical mechanical heat or solvent treatment The term is used in the textile manufacturing industry to denote fabrics such as felt which are neither woven nor knitted [1] Some non-woven materials lack sufficient
This book reviews the key technologies and characteristics of the modern man-made specialty fibers mainly developed in Japan Since the production of many low-cost man-made fibers shifted to China and other Asian countries Japanese companies have focused on production of high-quality high-performance super fibers as well as highly functionalized fibers so-called 'Shin-gosen' ZylonTM and
Since stereocomplexation or stereocomplex formation between enantiomeric PLA poly(L ‐lactide) [i e poly(L ‐lactic acid) (PLLA)] and poly(D ‐lactide) [i e poly(D ‐lactic acid) (PDLA)] was reported in 1987 numerous studies have been carried out with respect to the formation structure properties degradation and applications of the PLA stereocomplexes Stereocomplexation enhances
02 10 2012Production of nanofibers by melt spinning United States Patent 8277711 Abstract: A process and apparatus for forming nanofibers from a spinning melt utilizing a high speed rotating distribution disc The fibers can be collected into a uniform web for selective barrier end uses Fibers with an average fiber diameter of less that 1 000 nm can be produced Inventors: Huang Tao
Nanofibers are made from various materials including from polymers of biological origin polymer blends or block copolymers or polymers with additives Possible methods for the production of nanofibers are electrospinning melt spinning centrifugal spinning bicomponent spinning followed by dissolution of the matrix and melt blowing
nanofibers can be electro spun from polymer solutions in a strong enough electric field The concentration of polymer in solution often determines its spinability and generally has a dominant effect On the fiber diameter d (nun) as well as fiber morphology Higher concentrations generally yield nanotibers of larger average diameter but the quantitative relationship between the solution
Jiang et al reported improved electrochemical properties in force-spun tin-containing carbon nanofibers [334] Characteristics and considerations In general electrospinning is a simple efficient method to produce ultrafine high-surface-area fibers from a wide variety of polymers The nanofibers can be easily functionalized and their compositional and morphological properties can be
Adsorptive nonwoven substrates are composite media that contain adsorbent materials within their fibrous structure the methods to incorporate adsorbents in nonwoven webs determine their adsorption capacity The key objective for hybridization is to immobilize the adsorbent while controlling the packing density and pressure drop of the composite media
The Handbook of Nonwoven Filter Media Second Edition provides readers with a fundamental understanding of nonwoven filter media It is one of the few books dealing exclusively with the subject and is primarily intended as a reference for people in the nonwovens industry (industry and academic researchers technical marketing and quality control personnel) and universities offering courses

Polymers are melt or solution spun to filaments which are stretched to high orientation The filaments are cut to staple fibers of 20 to 80 mm length carded crosslapped and finally strengthened For implant applications where high volume nonwovens are required calendering as well as chemical or thermobonding are less suitable because they reduce the porosity We prefer a needling process

The method can use spunbonded melt blown or electro-static spun techniques for depositing solidifying filaments on the microporous surface such that the non-woven material conforms to the contour of the drum The drum facilitates continuous production of non-woven articles with three-dimensional shapes such as surgical masks or pleated air filters Airflow through the drum can be controlled
He focused especially on the development of multifunctional fibers yarns and fabrics engineering which has led to new engineering technologies especially melt-blown nonwoven fabrics He also introduced the notion of a generic type of uniform for the joint service of the Army Navy and Air Force which led 15 years later to the current joint service lightweight integrated suit technology
