Surface appearance irregularity of nonwovens

Visual and subjective methods for evaluation of surface appearance irregularity of chemically bonded nonwovens are compared. The image analysis system LUCIA is used for estimation of characteristics describing appearance. The analysis of subjective and objective estimates of surface appearance irregularity is realized by the coefficient o..

More spunbonding machinery builders reflect widening interest

The versatility of and growing interest in spunbonding technology was reflected at ITMA '99 by the number of exhibitors offering machinery designed for the sector. Lurgi Zimmer AG of Germany presented their latest lines, as did Hills Inc, Fleissner and ICBT-Perfojet. The latter described its new modular SPUN jet system, suitable for both ..

Refinements facilitate greater versatility in chemical bonding

At ITMA '99, Bruckner Apparatebau of Germany featured its wide range of spray-bonding and associated equipment. It promoted its ability to design, supply and install complete bonding and finishing lines for manufacturing various types of waddings and high loft nonwovens for apparel, furniture and other end uses.

Thermal-bonding advantages

Several exhibitors at ITMA '99 stressed the economy, energy efficiency and high quality advantages associated with calender and through-air thermal-bonding systems. KTM Kleinwefers introduced its new Parotherm Roll, designed to process fibre webs at>250℃ at speeds of 600 m/min. Kusters has developed a high-speed ultrasonic bonding calend..

Machines for mechanical web bonding

Mechanical bonding of fibre filament webs is gaining popularity because of the textile character obtained, the recycling potential and the wide range of application - which includes composite nonwovens. Companies exhibiting at ITMA '99 are highlighted, particularly those featuring needling machines, water-jet entanglement, stitch bonding ..

Technical textiles and nonwovens on the March

The 13th ITMA staged in Paris in June '99 managed to overcome poor expectations to emerge as a success for the industry. Machinery for producing technical textiles and nonwovens was well represented at the exhibition. The weaving sector is now recognising the need to offer models suitable for producing technical textiles.

Nonwoven product trends

In addition to the well established hygiene and medical applications, technical products dominated in nonwovens development trends at Index '99. Some 300 innovations were on show, with exhibitors focusing an web-forming and bonding processes, new fibres, water jet vortexing, SMS nonwovens and lightweight products. Antimicrobial finishes w..

Growth Opportunities in Technical Textiles and Nonwovens in Asia.

Western European consumption of industrial fabrics increased from 1.67 million tons in 1985 to 2.37 million tons in 1995 and is forecast to reach 3.1 million tons by 2005. North American consumption totaled over 3 million tons in 1995 and will reach 3.9 million tons in 2005. Consumption in the People's Republic of China will increase from..

Determining the Dynamic Efficiency with Which Wiping Materials Remove Liquids from Surfaces

A novel test for dynamic wiping efficiency, or wipe-dry, characterized 11 commercially available fabrics used to manufacture industrial wipes for food service, industrial, and cleanroom applications. The dynamic test more closely represents real end use conditions than conventional static tests. Fabrics constructed by hydroentanglement ge..
