Sorbents from wool as an alternative method for recycling low-quality raw material (Polish) )(Sorbenty z welny owczej jako alternatywny sposob zagospodarowania surowca niskiej jakosci)

The recovery of low-quality wool for recycling is considered. The conversion of this wool into absorbers is examined and their use in absorbing various emulsions, including oil/water emulsions, is discussed.

Recycling.....new options for Europe

The establishment of an automatic carpet sorting facility is an important step towards a European-wide carpet recycling system. A new development by Carpet Recycling Europe in Germany plans to recovery around 10% of the polyamide carpets used in Western Europe. The company, formed from a consortium of carpet fibre producers, expects to pr..

Latest fibre production equipment reflects changing demands

Fibre makers in Europe are turning away from traditional commodity markets to exploit the potential of the still expanding high performance and industrial sectors. As a result their demands on machinery builders are changing. This trend becomes more apparent when several machinery makers and raw material suppliers are regrouping. Saurer's..

Method of determining a volumetric percentage of air in a fiber suspension in a paper-making machine

In a paper-making machine, a method of determining a volumetric percentage of air in a fiber suspension for delivery to a headbox. The fiber suspension is transported through a fluid conduit. A sound transmitter and a target receiver are positioned relative to the fluid conduit. A sound is transmitted through the fiber suspension from the..

Limiting orifice drying medium, apparatus therefor, and cellulosic fibrous structures produced thereby

A limiting orifice through-air-drying medium for papermaking or other absorbent embryonic webs. The medium may be used in an apparatus which can be embodied in a cover and a roll. The medium has the unique combination of a relatively high binding fatigue strength and relatively low pressure drop. The medium may comprise a laminate of a pl..

Process and apparatus for treatment of fibrous raw material

The invention relates to a process and apparatus for pretreating pulp raw material, to be subsequently prepared in a chemical pulping process, and for preparing cellulose pulp from a fibrous starting material. According to the process the starting material is delignified to yield a chemical cellulose pulp, and the obtained pulp is bleache..

Bioactive and biodegradable composites of polymers and ceramics of glasses and method to manufacture such composites

Surgical osteosynthesis composite material which has three components: biodegradable polymer reinforcement, bioceramic or bioglass filler reinforcement and biodegradable polymer matrix. This invention relates to biodegradable materials used for bone fracture fixation devices and methods of their manufacture. Unlike other known materials u..

Injection moulded parts reinforced with flax fibre

VTT Chemical Technology - in collaboration with industry and the University of Oulu - has developed a manufacturing process in which flax fibre is used as reinforcement in injection molded thermoplastic components. The company claims that the method reduces the amount of plastic matrix usually required by a third, and other advantages inc..

Effect of glass fiber and maleated ethylene-propylene rubber content on texile and impact properties of Nylon 6

The Izod impact strength and tensile properties of blends Nylon 6 and maleated ehtylene-propylene rubber (EPR-g-MA) reinforced with glass fiber as a function of glass fiber and EPR-g-MA content were examined. Materials containing 0-20 wt% glass fiber and 0-20 wt% EPR-g-MA were formulated. The modulus and yield strength of the unreinforced..
