摘要:
The invention relates to a method for cleaning textile fibres or other materials which comprises contacting said textile fibres or other materials with a finely-divided particulate material, the particles of which have a capacity to adsorb oil, grease and other contaminants. The invention also relates to a method for controlling parasitic infestations in animals involving the finely-divided particulate material and an apparatus for cleaning textile fibres or other materials.
摘要:
A system (10) is provided for treating a mixture (12) containing desired materials (14) and contaminating plastic materials (16) for separation at a subsequent material processing stage. The system (10) comprises a treatment station (18), guiding means (24, 25, 30) for guiding the mixture (12) into the treatment station (18), and heating means (20) for heating a fluid medium flowing in said treatment station (18). The heating means (20) is arranged so that the mixture (12) at said treatment station (18) is heated to a temperature within a predetermined temperature range below melting points of the plastic materials. When heated to that temperature and exposed in the treatment station (18) within a predetermined time period the contaminating plastic materials (16) change their physical characteristics to a form allowing separation a the subsequent material processing stage. The system is particularly useful for removing plastic fibers from natural fibers such as wool, cotton or silk.

A wide variety of end products may be manufactured from fibers or fiber pulp derived from feathers. Examples of such end products are paper and paper-like products, non-woven and woven fibers, insulation, filters, extrusions, and composite sheets and plates.

摘要:
An apparatus for accurately detecting extraneous matter, such as cloth fragments, colored cotton fibers or seeds, which is contained in raw cotton and different from raw cotton in color. The extraneous matter different in color from the raw cotton is detected by a sensor (34) opposed to a colorless transparent wall portion (36) defining a passage (35) for transporting the raw cotton by an air stream. The outlet of the passage is continually opened and closed by a shutoff valve (33) for the air stream to transport the raw cotton intermittently and for the sensor to detect the extraneous matter while the cotton is at rest.
