SPINNING
MACHINES AT ITMA ‘03 ABSTRACT The paper reviews new developments in spinning machinery as judged from the exhibits at the recent (‘03) ITMA. There were few surprises and the offerings were mainly improvements in existing technologies. The most notable features were the introduction of a new rotor machine by Savio, the new Murata vortex spinning machine, and novel approaches to compact spinning. KEYWORDS:

Control Systems
at ITMA 2003 ABSTRACT A comprehensive analysis of the current trends and technologies in control systems for the textile industry is presented. Our approach was first to dissect the important components of an integrated control system and then to determine if and how the components are converging to provide manageable and reliable systems throughout the chain from fiber to the ultimate customer. Although the implementation of advanced process control strategies is not foreseen in the immediate future, it is apparent that the textile industry is slowly moving toward modular machines and systems. The dedicated systems still prevalent today are gradually being replaced by standard units, distributed automation concepts and an increasing connectivity of the production floor with planning and scheduling systems. This level integration has the potential to optimize the information flow throughout the entire Supply Chain. KEYWORDS: Control systems, Supply Chain, information flow, process

| Weaving
and Weaving Preparation at ITMA ’03
Abdelfattah M. Seyam ABSTRACT This paper extensively reviews the advances in weaving and weaving preparation at ITMA 2003. Whenever appropriate a technical background and/or critical comments are provided. ITMA 2003 has brought to weavers major technological advances that will help weavers to fully control their machines electronically from user friendly interfaces, produce broad range of woven fabrics, manufacture intricate jacquard designs at the speed of commodity fabrics, form leno fabrics faster, inspect fabrics on-loom, use optical and laser detection of warp break, reduce down time due to higher level of automation and quick style and warp beam change.

| KNITTING
Timothy W. Ellis
Timothy W. Ellis of ITT Technologies, Inc. reviewed the knitting exhibits at the ITMA exhibition held in October 2003 in Birmingham, England. The review includes details of weft and warp knit machines or technical modifications that were unique from previous exhibitions. The review also includes several related items in support of knitting. KEYWORDS: Knitting, ITMA 2003, Warp Knitting, Circular Knitting,

Wet processing equipment for preparation was reviewed at ITMA
2003. No major innovations were seen, but several interesting offerings
are summarized. |

LONG STAPLE PROCESSING AND TEXTILE TESTING Dean R. Cobb ABSTRACT Several vendors in the long staple processing area and the textile testing unveiled some improvements to their existing offerings. The long staple improvements came in the form of better design, more productivity, more electronic controls, less maintenance requirements, versatility, and cross compatibility with automation of all types. Improvements from some testing vendors mainly concentrated on yielding more information from the same tests; like the sticky cotton measurement from Lintronics and Weavability from Uster.

| ITMA 2003 Mechanical Finishing
R. Scott Bagley ABSTRACT Many general trends in the mechanical finishing area follow those in other areas of the textile world. Many of the companies are consolidating and combining representatives in the market place. Other trends include incremental improvements in machinery and monitoring techniques. There is a noted increase in the degree of technology used to monitor machines both visually and otherwise. The greatest emphasis in the mechanical finishing areas was obviously more efficient and higher quality means to alter the hand characteristic of fabrics. These techniques are seen as cost effective means to add value to a finished fabric and create distinction in finished products. Finally, many vendors highlighted changes and modifications to equipment designed to reduce costs. Energy savings, consumption data, and reducing required operator intervention were highlights in many vendors’ presentations. Following are some specific vendor highlights to elaborate on theses trends. Other vendors may offer similar features. This is not intended to be exhaustive, but representative of general trends.

Staple Pre-Spinning Machinery at ITMA ’03
Wade Carter ABSTRACT Short staple pre-spinning machinery shown at ITMA’03 in Birmingham, England emphasized compact opening lines with integrated multi-functional equipment. New technologies in carding included new machinery design, monitored and controlled waste removal, and a lengthened carding zone. Drawing innovations included a self-optimizing system for setting the break draft and an automatic quick adjustment of roller spacing. No new developments were shown in the short staple lap winding and combing areas. The only interesting feature shown on roving machines was a quick doffing system.

| ITMA 2003: REVIEW OF AIR-TEXTURING/INTERMINGLING
Nikhil Dani ABSTRACT Air textured yarns are produced from thermoplastic, cellulosic
or non-organic filament yarns using compressed air. Loops are formed
on the surface of the filament yarn, giving it a voluminous character.
Depending on the material used, the loop structure results in a
yarn with characteristics resembling those of conventional staple-fiber
yarn. The resulting yarns are used for sewing thread applications,
apparel fabrics, fancy yarn articles, automotive interior fittings,
and home furnishing fabrics, carpets, fire blankets and a wide
range of other applications. This report presents a review of the
latest developments in air-jet texturing/intermingling machinery
and nozzle manufacturing from around the world that were on display
at ITMA 2003 in Birmingham U.K. |

ITMA 2003 Review: Textile
Printing
Leon S. Moser ABSTRACT This paper reviews
the new developments shown at ITMA ’03
in the textile printing area. New equipment and techniques were
exhibited for flat screen printing, rotary screen printing, and
transfer printing. However, the area of digital ink jet textile
printing appeared to generate the most overall interest both from
the exhibitors’, as well as, the attendees’ point of
view. Most people interested in the textile printing area seemed
to feel that ITMA ’03 was highly successful.

The North Carolina Textiles Project: An Initial Report Patrick Conway*, Robert Connolly**, Alfred Field* and Douglas
Longman* ABSTRACT The phenomenon of increasingly contested international markets due to falling price and non-price barriers to trade in goods and services is one often-discussed dimension of globalization. The textile industry in particular is cited as an example of the dangers of globalization to US firms, workers and communities. Both US economic growth and the standard of living are thought to have fallen as a result of globalization in this industry. KEYWORDS: globalization, manufacturing, plant analysis |

ROUND IS STALLED; NOT STOPPED
Sid Smith ABSTRACT Don't believe everything you read when you see that this latest round of multilateral trade negotiations (the Doha Round) is over and financed with because of the inability to reach an agreement in Cancun, Mexico. All of this has happened before in other rounds and they have all been resurrected and carried to completion. This one will too and here's why and how. KEYWORDS:
