Patent JP-H06200016-A (JP)
Title: Production of biodegradable plastic
Inventor: IKEDA TOSHIKI
IPC: C08G69/44
Filed: 1992-12-28
Abstract: PURPOSE:To obtain a biodegrdable plastic being homogeneous and having sufficient strengths by subjecting a cyclic ester and a cyclic amide to a ring-opening copolymerization reaction and removing excessive monomer, water, etc., by evacuating the reaction vessel. CONSTITUTION:A cyclic ester such as beta-propiolactone, beta-valerolactone or epsilon- caprolactone and a cyclic amide such as 2-pyrrolidone, 2-piperidone or epsilon- caprolactam are subjected to a ring-opening copolymerization reaction to produce a biodegradable plastic comprising a polyester amide copolymer composed of polyester blocks and polyamide blocks randomly bonded to each other. After the above polymerization reaction, the polymerization and purification are performed by removing excessive monomers and water from the reaction vessel by evacuation to obtain a biodegradable plastic which need not be purified with a solvent. By adding acetic acid to the reaction mixture after the polymerization reaction, the formed polymer can be decolored.

Title: Twisted yarn with special structure and treatment thereof
Inventor: IIDA HIROHIKO
IPC: D02G3/26
Filed: 1995-12-07
Abstract: PROBLEM TO BE SOLVED: To obtain a real-twist, long-period, SZ-alternate twisted yarn with uniformized appearance by jointing SZ-alternate twist conversion spots imparted in a specific period to obviate flaws of SZ twist conversion spots in the knit fabrics made thereof. SOLUTION: S-twist and Z-twist are imparted alternately in the long direction in a length greater than the weaving width for a weaving machine (hereafter, referred as long period), and SZ-twist conversion spots are jointed, thus obtaining the objective real-twist, long-period, SZ-alternate twisted yarn either not subject to untwisting or subject to only partial untwisting of the SZ-twists by application of tension in the yarn axial direction. The jointing is carried out through interlaceing (e.g. Taslan entanglement), fusing, bonding, wrapping or fluff interlaceing means. A weaving is conducted by a patch weaving machine so that the joints represent selvedge end yarns, and the SZ-conversion spots are ensured not to contain by such a means as to remove the joints after woven.
