摘要： At least two different liquid streams are sub-divided into a dense plurality of individually separated parallel pixels oriented in respective misregistered arrays. Therefore, an individual pixel of one of the liquid stream arrays will be surrounded by pixels of the other liquid stream array. These individual pixel arrays are then bought into contact with one another to form a multi-pixel liquid stream comprised of the misregistered pixel arrays of the two different liquid streams. The “pixelated” liquid stream—that is, the liquid stream containing in cross-section the misregistered pixel arrays of the two different liquid streams—may then be further processed. For example, the pixelated liquid stream may be subjected to further mixing by being directed along a tortuous flow path.

摘要： A melt-extrudable polymeric strand with altered physical properties formed by extruding an emulsion comprising a melt-extrudable polymer and an immiscible component while subjecting the emulsion to ultrasonic energy. In one embodiment, a melt-extrudable polymeric strand has a plurality of fissures in the surface of the strand such that the strand has a B.E.T. surface area to six times the B.E.T. surface area of an otherwise identical strand lacking the plurality of fissures. Desirably, the strand of this embodiment has a B.E.T. surface area of within a range from about 0.10 to about 0.18 m.sup.2 /g. In a method for making such a strand, the immiscible component of the extrudable emulsion comprises a substance that is an expandable gas upon extrusion. The expandable gas forms the fissures in the strand. According to another aspect, a polymeric strand has a continuous phase which is a melt-extrudable polymer and a disperse phase which is immiscible with the continuous phase. The disperse phase forms discrete pockets of material in the extruded strand and can include a variety of components which alter the physical properties of the strand. Suitable components of the disperse phase include water, aqueous solutions, oils, low melting point metals, and other physical property altering materials.

摘要： A multi-layered conjugated acrylic fiber comprises different polymers which are conjugated along the fiber axis in layers. On the average the fiber contains more than two layers of acrylic polymers. The shrinkage forming ratio in boiling water of the conjugated acrylic fiber is 7-15 % and the shrinkage forming stress is 5-20 mg/denier. To make the acrylic fiber water absorbent, one or more of the acrylic polymers may contain 0.3 to 2.0 mmole/g of carboxylic acid groups. The fibers may be made by introducing the polymers into a static mixer in such a way as to retain a number of separate layers of the polymers, and thence to a spinneret through a filter having a maximum mesh space of the 10 um or more. After spinning out the dope, it is drawn, washed and dried. Except where water-absorbent fiber is wanted, this is followed by shrinkage forming treatment and redrawing; the water-absorbent fiber is treated with alkali solution either in the form of yarn, or a fabric made therefrom.
