Nowadays, textile processing based on biotechnology has gained its importance in the view of stringent environmental and industrial safety conditions. The use of protease enzymes in protein fibers to improve some physical and mechanical properties is particularly interesting. In this research, wool yarns were first treated with different concentrations of protease enzymes in aqueous solution in...

The persistence of Staphylococcus aureus (Smith) on wool blanket, wool gabardine, cotton sheeting, cotton knit jersey, cotton terry cloth, and cotton wash-and-wear fabrics was studied. The fabrics were exposed to bacterial populations by three methods: direct contact, aerosol, and a lyophilized mixture of bacteria and dust having a high content of textile fibers. The contaminated fabrics were h...

Traditionally, wool fibers are dyed with acid dyes at the boil, which is energy-intensive process, and increases cost of dyeing. The development alternative energy-efficient dyeing processes quite attractive to textile industry make sustainable. In this work, feasibility low-temperature fabric several aniline sulfonic (ASA) derivatives by oxidative polymerization method was investigated. effect...

In this research, the adhesive wear of a composite material consisting unsaturated polyester has been studied as matrix reinforced by glass fiber and rock wool fibers. The rate property is compared in normal condition after immersion (NaOH) (HCl) solutions at normality (0.3N) laboratory temperature (25 oC) for 30 (days) with fixed volume fraction (20%). results showed that decreased increasing ...
