Acrylic and Acetovinylic Polymers for Preserving and Restoring Cotton Textiles

With the aim of better understanding the phenomena related to the application of polymeric materials on natural fiber textiles for restoration purposes, six commercial polymers based on acrylic and acetovinylic monomers are tested on modem cotton textiles. Cotton samples are impregnated with water dispersions of these polymers. The morpho..

Thermal Storage/Release and Mechanical Properties of Phase Change Materials on Polyester Fabrics

Melamine formaldehyde microcapsules containing octadecane are synthesized by the interfacial polymerization method, and the size, shape, and thermal storage/release prop erties of the synthesized microcapsules are analyzed by FTIR, SEM, and DSC. Polyester fabrics are then coated with the microcapsules under various conditions of concentra..

Circumferential Superdrawing of Hollow Poly(ethylene Terephthalate) Filaments

Amorphous poly(ethylene terephthalate) (PET) can be stretched at low tension without causing any observable crystallization at temperatures above Tg. This resultant increased length with no measurable change in orientation is called superdrawing. Superdrawing of hollow PET fibers in the circumferential direction is demonstrated in a hot w..

Simulating Cavitation and Hydraulic Flip Inside Hydroentangling Nozzles

Hydroentangling owes its success to the peculiar properties of coherent water jets. For hydroentangling to be feasible at higher pressures, it is extremely important that water jets maintain their collimation for an appreciable distance downstream of the nozzle. How ever, water-jet breakup accelerates at high pressures. Recent studies hav..

Effect of Ceramics on the Physical and Thermo-physiological Performance of Warm-up Suit

The purpose of this study was to develop a warm-up suit that is comfortable as well as having a good thermal performance. Heat-insulating water vapor-permeable fabrics for warm-up suit were developed by applying ceramic powders to hydrophilic polyurethane films, which were then incorporated into textiles. Two types of ceramic compounds we..

Simulation of the Effect of Air Gaps between the Skin and a Wet Fabric on Resulting Cooling Flow

As the moisture content of a fabric increases, the relative water vapor permeability (the relative heat flow responsible for the cooling of the body) also increases and the fabric temperature drops due to the evaporation of the water from the surface of the fabric. In this work on the experimental study of water vapor permeability of wet ..
