microstructure of fabrics chemically finished for thermal adaptability

a new 'comfort' property, a warming and cooling effect, has been designed into textile fabrics by finishing them with polyethylene glycol solutions. high polymer add-ons result, changing the physical nature of the fabrics. finished and unfinished cotton, cotton/polyester, and wool fabrics were compared using optical and electron microscop..

industrial prospects for chitin and protein from shellfish wastes,

although chitin and derivatives of chitin have been studied for many years and their intriguing chemical properties have been known, commercial utilization has been almost nonexistent. this study was designed to address the industrial prospects for utilization of chitin. a business strategy involving both chitin and protein from shellfish..

Antimicrobial Fabrics for Bio-Protective Clothing and Textiles.

Researchers developed durable antibacterial fabrics based on a regeneration principle and reversible redox reactions. In previous studies, experiments used the N-halamine compound MDMH (Anti-1) in a chemical finishing process and covalently linked onto ce

Klopman introduces fabric for healthcare wear

Klopman is expanding its range of workwear fabrics to include Melody, a midweight pique weave fabric, suitable for women's wear in the healthcare and service sector. Melody is a polyester/cotton blend which is easy to care for and durable enough to withstand industrial laundry temperatures. It is available in a wide range of colours and l..

Semicontinuous Plasma Treatment of Textiles.

Low pressure plasma technology alters material surface properties for such industrial applications as fine cleaning of parts before adhesive bonding, surface activation of plastics to improve the adhesion of primers or paints, and imparting scratch resist

Durable and regenerable antibacterial finishing of fabrics

Antibacterial functions can be chemically imparted onto cellulose containing fabrics. The finished fabrics exhibit durable and regenerable biocidal properties. The functional fabrics are very effective against gram positive and gram negative bacteria such as Staphylococcus aureus and Escherichia coli Mechanical properties as well as bioci..

Polyester fibres modified with β-(5-nitro-2-furylo) acrolein

An effective process to impart antibacterial properties to fibres by the modification of polyester fibres with β-5(nitro-2-furylo) acroelin (NFA) has been developed. The quantity of NFA added to the fibres depends on swelling agents present in the impregn

Coverage of immature cotton neps in dyed fabrics using chitosan aftertreatment

Neps of immature cotton fibers appear as light or white specks in a dyed fabric. This is a serious problem and a major cause of fabric rejection. Since white specks due to neps of immature cotton are visible only after the value-added processes, it would be highly desirable to have a process to cover the neps in the dyed fabrics by using ..

Chitin and Chitosan -- New Textile Materials.

Chitin is a natural polymer derived from a range of plants and animals, but mostly from the shells of crustaceans. Preparation of chitosan requires deacetylation in concentrated alkaline solutions. Important properties include biodegradability, biocompatibility, and ease of chemical modification. Applications range from pharmaceuticals an..

Chitosan-Based Hydrogels as Biomaterials.

Researchers analyzed a method of preparing hydrogels via complexation of chitosan and xanthan. Electron microscopy revealed a fibrillar structure with characteristic pore size of 10(-7) and 10(-6) meters. The chitosan-xanthan complex can be used to immobilize xylanase, hemicellulase, hydantoinase, protease, and lipase. The activities of t..
