Moving beyond cost to quality issues, some companies are playing the “choice” card.

Abstract
The World Wide Web has undergone a rapid transition from the originally static hypertext to an ubiquitous hypermedia system. Today, the Web is not only used as a basis for distributed applications (Web applications), moreover it serves as a generic architecture for autonomous applications and services. Many research work has been done regarding the modeling and engineering process of Web applications and various platforms, frameworks and development kits exist for the efficient implementation of such systems. Concerning the modeling process, many of the published concepts try to merge traditional hypermedia modeling with techniques from the software engineering domain. Unfortunately, those concepts which capture all facets of the Web’s architecture become rather bulky and are eventually not applicable for a model‐driven Web application development. Moreover, there is a need for frameworks which address both, the modeling process and the implementation task and allow a model driven, semi‐automatic engineering process using CASE tools. This paper outlines the DaVinci Web Engineering Framework which supports the modeling as well as the semi‐automated implementation of Web applications. The DaVinci Architectural Layer specifies a persistent, hierarchical GUI model and a generic interaction scheme. This allows the elimination of the hypermedia paradigm, which turned out to be rather practical when building Web applications.

Abstract
Purpose
The textile sector struggles with cotton stickiness from honeydew contamination. It hurts agriculture and marketability. This study aims to examine how bacterial enzymes could reduce honeydew-contaminated cotton adherence in textile businesses sustainably.
Design/methodology/approach
Enzyme was extracted from bacteria isolated from the fermented bamboo shoots “Lung siej”. The enzyme was tested for α-glucosidase using p-nitrophenyl-α-D-glucopyranoside as a substrate. Design of experiments determined enzyme activity temperature and reaction time. Laboratory-prepared artificial honeydew was added to ginning mill cotton to show honeydew contamination. After enzyme treatment, sticky cotton was tested for microscopic examination, ultraviolet (UV), Benedict’s, Elsner colorimetric, high volume instrument (HVI) and viscosity tests.
Findings
The bacterial isolate is characterized as Lysinibacillus sp. as confirmed by 16S rRNA gene sequencing. The enzyme extracted was identified as α-glucosidase. The ideal temperature and reaction time for enzymatic activity were 32 °C and 35 min, respectively, using central composite design. The microscopic examination, UV test, Benedict’s test, Elsner colorimetric test, HVI test and viscosity test showed that bacterial enzyme treatment reduced cotton fiber adherence.
Originality/value
Although few patents have examined the effect of yeast enzymes, to the best of the authors’ knowledge, a bacterial enzyme is investigated for the first time to reduce the adhesion of honeydew-contaminated cotton.

Abstract
Examines the tenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

Abstract
The aim of this study was to determine the effects of two popular web-forming technologies, viz., the Rando air-laid technology and the traditional carding and cross-laying technology, on properties of the hydroentangled nonwoven fabrics made therewith. A mill-like fiber processing study was conducted in a commercial-grade pilot plant using a variety of short staple fibers and their blends. The fibers used in the study were greige cotton, bleached cotton, cotton derivatives, and cut-staple polyester. The hydroentangled fabrics produced with the two systems were mainly evaluated for their physical and mechanical properties, absorbency, absorbency capacity, and whiteness. The study has shown that, with the exception of greige cotton linters, the greige cotton lint, greige cotton gin motes, and even greige cotton comber noils, either alone or in blend with the other fibers mentioned, can be mechanically processed into hydroentangled nonwoven fabric structures without any insurmountable difficulties. The drop test and sink time followed each other pretty closely, as the drop test time increased so did the sink times. The "whiteness" of fabric, which is significantly more dependent on the fabric's constituent fiber content than on the fabric's surface-based light reflection, obviously varied considerably. However, the whiteness index within the same fiber types and their blends shows no trend of significant difference between the fabric produced with carded fiber web and the fabric produced with random Rando fiber web. Incidentally, the Rando sample of bleached cotton was not available. Since the nonwoven fabrics of this discussion generally are disposable, the optional use of ‘brighteners’ to improve whiteness of certain whiteness-deficient fabrics may be considered as long as the brighteners do not easily bleed from the fabrics.

Abstract
The aim of this research is to develop greige (raw/non-bleached) cotton-containing nonwoven fabrics that likely would be competitive in quality, cost and performance to existing products that presently and predominantly use man-made fibers and some bleached cotton for wipes and other similar end-use nonwoven products. Since the whiteness and absorbency of these end-use products generally are the most desired and perhaps even critical attributes, the research was mainly focused on attaining these attributes by exploring various choices and optimum use of a variety of cost-effective cotton fibers and the blends thereof with other fibers. Nonwoven fabrics were produced, via a modern hydroentanglement system, with possible choices of using several types of cotton fibers, including the greige cotton lint and certain of its co-products such as gin motes and comber noils, and their various blends with polyester and nylon staple fibers. Bleached cotton was also used to produce an equivalent fabric for comparison. The research has shown that although the desired and perhaps critical properties of whiteness and absorbency of the selected fibers vary considerably among the various fabrics produced, the blends of greige cotton lint with man-made fibers can provide the fabric whiteness and absorbency comparable to those of say, a, bleached cotton fabric. The research results suggest that the greige cotton lint and/or its co-products in blend with polyester fiber may be sensible approaches to the development of functionally acceptable nonwoven wiping products that are also environment friendly.

Abstract
Remarks on the parallel in the basis of the riches of the aristocracy and plutocracy. Illustrates the argument from the history of the development of the cotton textile industry, the underpinnings for its growth being the inventions prior to and during the eighteenth century. Exemplifies the part of inventions as the begetter of plutocratic wealth. Sir Richard Arkwright, notably, was its salacious issue.
