A disulfide-containing polyester indicates a dynamic nature in a bulk state based on a disulfide metathesis reaction driven by photoirradiation.

In this research, an attempt was made to improve the brittle nature of Unsaturated Polyester (UP) polymer which cannot undergo plastic deformation be improved become more resilient by adding Thermoset Vinyl Ester and Methyl Methacrylate (MMA). To show change in toughness polyester material, a test is carried out provide tensile load flexural until material breaks This work reports successful fa...

In recent years, the improvement of properties of natural fibre reinforced laminates over the pure polymeric matrix has been thoroughly investigated with the aim of providing a possible replacement of E-glass fibre reinforced composites for some large-volume applications. In the present study, the properties of a jute/polyester laminate are compared with those yielded by two E-glass fibre woven...

cotton/polyester knitted fabrics as a major production of textile industry was treated with titanium dioxide nanosized particles. the treated fabric with nanosized tio2 became whiter with a good self-cleaning property. also the discoloration of reactive black 5 dye was studied and reported. the stabilization of tio2 on cotton/polyester knitted fabrics by citric acid (ca) with sodium hypophospha...

one of the common methods to cure unsaturated polyester resins is to use dual initiators. in order to produce an appropriate composite, it is necessary to know the effect of dual initiators on curing behavior. in this paper the effect of benzoyl peroxide, bpo, and tertiary butyl perbenzoate, tbpb, and their mixtures on thermal curing of an unsaturated polyester resin have been investigated. bpo...

Polyester is the most ubiquitous fabric for textiles. In 2021 textile production in world amounted to 113 million metric tonnes, of which 54% was polyester. Yet, we seem know very little about this important fiber textiles and apparel. This article fills that gap by tracing a cultural history critique There are several phases reception polyester, invented early 1940s. From initial suspicion 195...

the objective of this study was to determine the effects of diets having different fermentability on blood gases, blood metabolites and ruminal fermentation parameters in holstein dairy cows. four multiparous holstein dairy cows (665 ± 25 kg bw, 170 ± 7.0 dim and 15±1.5 kg of milk yield), fitted with rumen cannulae, were used in a 4×4 latin square design with 28-d periods. corn starch and sucro...

high fructose corn syrup (hfcs) is commonly found in soft drinks and juice beverages, as well as in many pre-packaged foods such as breakfast cereals, baked goods and dairy desserts. historically, sucrose (table sugar) was primarily added to processed foods and beverages as the sweetening agent. in recent years, the use of hfcs has significantly increased in popularity due to its sweetness, abi...
