Production of lyocell fibers in western Europe

The current commercial situation relating to the production of lyocell solvent-spun cellulosic fibres is reviewed. Lenzing are starting a production plant in Austria in July 1997 with an initial capacity of 12 000 tonnes per annum and plan to double this within two years. With Courtaulds bringing on a further 42 000 tonnes per annum at th..

A vision of AATCC in 2021: anticipated changes over the next 25 years

The author, a former AATCC vice-president and chairman of the ad hoc committee on strategic planning, presents his vision of the Association's possible pathway into the 21st century.

Multicomponent yarn via liquid injection

A multicomponent fibre comprises: a first, continuous, longitudinally extensive domain formed from a blend of a first thermoplastic polymer with a particulate additive dispersed in a liquid organic rosin carrier; and a second, continuous, longitudinally extensive domain consisting of a second thermoplastic polymer arranged coextensively w..

Mechancial properties and crosslinking structure of water-soluble vinylon fibers treated with epoxides (Japanese)

Water-soluble Vinylon fibers (dissolving temperature is 25℃) were treated with di-functional or multi-(di-and tri-) functional epoxides in Heat-system (Hs) and Solution-system (Ss). Mechanical properties for treated fibers were measured in dry-condition (20℃ 65％RH) and wet-condition (in water). SEM observation was performed under wet-c..

Study on the intensity changes of free radicals in aramid fiber (Chinese)

After pretreatment with strongly-interacting solvents, dimethyl-formamide (DMF) and dimethyl sulfoxide (DMSO), and then with the ultraviolet radiation and low temperature plasma treatment, the relative free radical intensity within the treated maramid Nomex (m-PIA) and p-aramid Kevlar (p-PTA) fibers were studied by means of electron-spin-..

Developments in MMF production. XXXII. Thermoplastic behaviour

The structure of most fibres consists of folded molecular chains or rigid molecules embedded in the matrix of random chains. This leads to different types of crystalline relaxations. By appropriate selection of processing conditions and solvents, it is possible to prepare fibres in different crystalline forms, with different thermoplastic..

Ecological friendly clothes based on flax and hemp fiber

The period from the 1950s to the 1970s was the time of dynamic development of man-made fibers which were applied in different fields of industrial activity including the textile industry. Yarns made of man-made fibers were used for apparel production repl

Textile Trade in First Half of 1997.

Japan's textile and apparel exports declined 4 percent to ＄3.57 billion during the first six months of 1997. Textile exports, however, increased 10 percent compared with the first half of 1996. Exports of acrylic staple fibers increased 6 percent to 146,000 tons. Exports of rayon staple fibers declined 10 percent. Exports of polyester st..

World Textile Trade and Production Trends.

An overview of production trends in the 1996 international textile industry highlights fiber production and consumption, including general trends, world cotton supply and demand, regional patterns of supply and demand, global wool supply and demand, and manmade fibers; trade and production trends by region and country, the United States, ..
