Cleaning and Conditioning Paper Machine Clothing for Recycled Fiber Use.

Recycled fibers create dewatering problems and contaminate paper machine clothing fabrics with such materials as fillers, sizes, dyes, plastics, adhesives, and waxes. Process optimization, such as removing tailings, separate stock preparation, and cautious use of recycled water, help minimize contaminants. General fabric cleaning consists..

Developments in MMF Production. Part LIII: Structural Analysis from Small-Angle Light Scattering.

Small angle light scattering (SALS) measures the shape and size of fiber superstructures and provides data with good agreement with that obtained from polarizing microscopy. SALS more accurately quantifies the spherulites and provides a statistical evaluation of sizes and shapes of scattering entities that are difficult to obtain through ..

Principal technical terms are defined and described in English, German, Spanish, and Italian. Morphological Scheme, terms an..

Biotechnology: The Bionidustrial Revolution Comes to Textiles. Part III.

The last installment in a series of three articles on the current and potential applications of biotechnology in the textile industry focuses on effluent treatment, the use of DNA and monoclonal antibodies in the identification of textile materials, and textile applications in biotechnology. Biotechnology in effluent treatment includes bi..

Textile Industry in Pakistan: A Profile.

The textile industry accounts for 68 percent of Pakistan's exports and 8.5 percent of its gross domestic product. It supplies 1.9 percent of the world textile market and is generally considered a supplier of standard or commodity products with limited range and lower than average quality, Although it has ample supplies of raw cotton and l..

Biochemical Removal of Caprolactam from Wastewaters.

The efficiency of caprolactam removal from industrial wastewaters using the biocenosis of activated sludge-caprolactam system depends on caprolactam concentration in the effluent, activated sludge concentration in the aerotank, and aeration duration and intensity. Effluent flow is critical to efficient aerotank operation and depends on re..

Purification of Caprolactam-Containing Waste-waters with Ion-Exchange Fibre Materials Based on Polypropylene Fibres.

A new method manufactured condensation polymerization filled cation exchange polypropylene fibers for the efficient purification of wastewater containing caprolactam. The level of purification depended on the volume of wastewater passed through the system. Experiments compared polyacrylonitrile, polypropylene, and modified polypropylene. ..

Chemical Recycling of Waste Saturated Polyesters and Urethane Polymers to Yield Raw Materials to Produce Polyurethanes.

A review of chemical recycling techniques of waste saturated polyesters and polyurethanes discusses glycolysis with ethylene, diethylene, propylene, or dipropylene glycol, one of the most frequently used methods. The recyclate can be used to make polyurethane foams, elastomers, and sealants. Waste polyurethanes can also be degraded by gly..

Report of the International Conference on 'Environmentally Oriented Textile Industries' -- Part VII. Disposal of Textiles and Interactive Seminar Methodology.

Germany consumes 26 kilograms of textiles per capita per year. Apparel accounts for 13 kilograms. Approximately dealers or donated, 15-30 percent is recycled as cleaning cloths, 15 percent is used in some other way, and 10 percent is disposed of as real waste in landfills. The Borgers Company in Berlin, a textile recycler with an faciliti..
