摘要： PROBLEM TO BE SOLVED: To produce a high-tensile strength recycled yarn having a high tensile strength and elongation by carrying out a recycling treatment of a waste plastic material from a thermoplastic such as polyethylene or polypropylene. SOLUTION: A thermoplastic waste plastic material is heated, melted, twisted and rubbed at a temperature in which about 1.8 times the melting starting temperature of the waste plastic material is the upper limit with a first melting machine, then passed through a filter and a nozzle to form a wiry material, which is subsequently cooled, hardened and cut into pieces with a shearing machine to form material pellets. The resultant material pellets are then heated, melted, twisted and rubbed at a temperature in which about 1.8 times the melting starting temperature of the material pellets is the upper limit with a second melting machine 25 and then passed through a filter 30 and a nozzle 31 to form a material yarn 21, which is subsequently cooled, hardened, then heated, softened, stretched and drawn with a drawing machine 35 to form a recycled yarn 22 having a prescribed wire diameter (denier).

摘要： PROBLEM TO BE SOLVED: To obtain uniform mixture useful for obtaining a homogeneous synthetic resin by mixing chips comprising plural kinds of thermoplastic polymers while removing static electricity charged to the chips when these chips are weighed and mixed at a definite ratio and melt-molded. SOLUTION: Chips (master chip and base chip) comprising two or more kinds of thermoplastic polymers are fed from a hopper 1 and a hopper 2, respectively. The master chip is fed into a transporting piping 6 of base chip while being weighed by a weighing and feeding device 3 and mixed with base chip at a definite ratio preferably at (80:20) to (99:1) mixed weight ratio of base chip to master chip} in a mixing part 5 and fed to an extruder 7 in a state packed in piping 6 and melt-kneaded and the melted resin is fed to a gear pump 8 group for quantitatively feeding the melted resin. In this time, an electrostatic charge-removing device 4 is provided in a chip discharge part of the weighing and feeding device 3 of master chip and the master chip is mixed with base chip while eliminating static electricity charged to the chip.

摘要： PURPOSE: To provide a method for stably producing a biodegradable monofilament used for an industrial material such as a fishing net, a laver net or a rope from a polymer of polyhydroxyalkanoates. CONSTITUTION: A polymer of polyhyroxyalkanoates having >=400000 weight- average molecular weight is melted at a temperature of (Tm+15) to (Tm+50) deg.C [Tm is the melting point ( deg.C) of the polymer] within 6min and the molten polymer is then introduced into a spinneret pack at a temperature of Tm to (Tm+15) deg.C and spun under conditions of 2×10 /sec shearing rate just on a filtration layer in the spinneret pack within 2min residence time in the spinneret pack. The resultant monofilament is subsequently cooled, solidified and crystallized in a liquid bath at a temperature of (Tc-10) to (Tc+10) deg.C [Tc is the crystallization temperature ( deg.C) of the polymer] for 5-10sec and then drawn without winding in feeding the polymer to an extruder, melt spinning the polymer, drawing and producing a biodegradable monofilament.

摘要： PURPOSE: To provide a yarn stretching chamber arrangement not causing trouble caused by static electricity and electrification. CONSTITUTION: The stretching chamber arrangement comprises a stretching chamber 1 with a first closeable feed conduit 5, a return conduit 7, a liquid container 3 and a pump means 4 for the circulation of the liquid through the stretching chamber and a separating chamber 2 with a suction conduit 9 and a suction pump 8 for sucking the liquid from the separating chamber. For premoistening the yarns F to prevent dry friction during the start-up of the arrangement, a second feed conduit 10 is provided and the second feed conduit 10 by-passes the closing means 6 of the first feed conduit 5 and opens out into the yarn duct through small premoistening openings situated in the direction of the yarn travel in the area of the yarn entrance in front of the first yarn guiding element of the arrangement.
