Phospholipid nonwoven electrospun membranes.
Nonwoven fibrous membranes were formed from electrospinning lecithin solutions in a single processing step. As the concentration of lecithin increased, the micellar morphology evolved from spherical to cylindrical, and at higher concentrations the cylindrical micelles overlapped and entangled in a fashion similar to polymers in semi-dilute or concentrated solutions. At concentrations above the ...
متن کاملNonwoven Padding for Compression Management
Nonwovens play an important and crucial role in the designing of appropriate struc‐ tures for healthcare and hygiene products. One such application is the use of nonwo‐ ven padding in a multi-layer compression system recommended for the treatment of chronic venous disorders. Padding helps in ensuring uniform pressure distribution underneath the bandaging layer wrapped around the circumference o...
متن کاملNonwoven scaffolds for bone regeneration
1. The structure of bone and the mechanisms for self-repair Bone is one of the most commonly transplanted tissues, with 2.2 million bone grafts performed annually worldwide (Tronci et al., 2013a). Surgeons face a diverse spectrum of clinical challenges in bone reconstruction, and this diversity reflects the variety of anatomic sites, defect sizes, mechanical stresses, and available soft tissue ...
متن کاملFiber Crimp Distribution in Nonwoven Structure
The crimp of the text ile fibers is very crit ical to determine its properties and volumin isity. The microscopic characteristic of the nonwoven fabric is totally depends on the linearity and length of the crimp and the amplitude of the crimp. In this review paper we have discussed about the crimp calculat ion, measurement techniques and the standards used for the text ile nonwoven substrates. ...
متن کاملObjective pilling evaluation of nonwoven fabrics
A pilled nonwoven fabric image consists of brightness variations caused by high frequency noise, randomly distributed fibers, fuzz and pills, fabric surface unevenness, and background illumination variance. They have different frequency and space distributions and thus can be separated by the two-dimensional dual-tree complex wavelet transform reconstructed detail and approximation images. The ...
