Patent number: 6030116Abstract: A system capable of measuring the heat and moisture transfer characteristics of thin materials such as clothing materials and the like simultaneously and accurately so as to obtain data for evaluating the suitableness of such material, for clothing. The sample 50 is set to partition the spaces 56 and 57, then the first and second types of air 1 and 2 which have been adjusted to the desired temperature and humidity flow into the temperature and humidity variation measurement section 53 in the desired amounts, respectively. The airs 1 and 2 are brought into contact with the temperature sensor 58 and the humidity sensor 59 at the inlet and outlet port of the section 53. An exchange of heat and moisture takes place between the air 1 and the air 2 through the sample 50. By measuring the temperature and humidity of the airs 1 and 2 at the inlet and outlet ports of the section 53, it is possible to understand the heat and moisture transfer characteristics of the sample 50.Type: GrantFiled: June 23, 1997Date of Patent: February 29, 2000Assignee: Nisshinbo Industries, Inc.Inventors: Yuichi Yanai, Mitsuo Sobajima, Tomiko Shiji

Patent number: 5910279Abstract: Creases are formed in a cellulosic fiber textile by treating the fiber textile with liquid ammonia, creasing the fiber textile, and treating the fiber textile with hot water or alkaline solution substantially simultaneous with or subsequent to the creasing step. Fully durable creases are formed in the cellulosic fiber textile without detracting from strength.Type: GrantFiled: April 11, 1997Date of Patent: June 8, 1999Assignee: Nisshinbo Industries, Inc.Inventors: Yuichi Yanai, Takayuki Hirai, Masayoshi Oba, Kiyoshi Ikeda, Yasushi Takagi, Takeo Ishikawa, Kazuhiko Harada, Hirotaka Iida, Kazuhiko Arakawa, Masazumi Ii, Yuzo Nakamura

Patent number: 5879410Abstract: A process for resin finishing textile containing cellulosic fiber comprises the steps of using a resin finishing agent chiefly containing a cellulose-reactive N-methylol compound having two or more functional groups and a reaction catalyst, mainly reacting only one functional group of the cellulose-reactive N-methylol compound with cellulose, water washing, again imparting reaction catalyst, drying, garment making, and heat treating. The process eliminates the conventional postcuring method drawbacks of loss of color fastness and discoloration owing to dye decomposition and formaldehyde increase by unreacted resin and residual reaction catalyst during long storage before heat treatment, and simultaneously achieves high crease-resistant property, shrink resistance, good feeling, excellent pleating property, and anti-puckering property.Type: GrantFiled: December 12, 1997Date of Patent: March 9, 1999Assignee: Nisshinbo Industries, Inc.Inventors: Yuichi Yanai, Masayoshi Oba, Yasushi Takagi, Tadashi Isogai

Patent number: 5813210Abstract: A twisting frame 1, and a method of twisting yarn 11 in which a twist is applied to the yarn by signals having a 1/f fluctuation to yield a yarn 11 in which the yarn count varies with a 1/f fluctuation. The first aspect is a twisting method that applies twist to a single yarn or a plural number of yarns, in which a twist is applied to the yarn or yarns by setting the twist count to correspond to the strengths of serial signals having a 1/f fluctuation.Type: GrantFiled: May 9, 1997Date of Patent: September 29, 1998Assignees: Toshimitsu Musha, Nisshinbo Industries Inc.Inventors: Toshimitsu Musha, Yuichi Yanai, Kazuyoshi Muraoka, Yuki Niwa, Yasuo Nakano

Patent number: 5758697Abstract: A weaving method that imparts a 1/f fluctuation to the weave pattern. Adjacent and different numbered groups of different yarns, for example black yarn and white yarns, are alternately arranged in contiguous reed dents. The sequential number which is associated with each group manifests a series of numbers which effect the 1/f fluctuation. Following separation of the warp yarns into two sets by raising and lowering of healds to form a shed and passage of weft yarns therethrough, a woven fabric with a stripped 1/f fluctuation in the warp direction is created.Type: GrantFiled: May 8, 1996Date of Patent: June 2, 1998Assignees: Nisshinbo Industries, Inc., Toshimitsu MushaInventors: Toshimitsu Musha, Yuichi Yanai, Shoji Takagi, Shu Ono

Patent number: 5727600Abstract: A weaving method that imparts a correlation of a 1/f fluctuation to the texture pattern of a woven fabric by passing warp yarns through a plural number of healds in a specific numerical sequence. The healds are then manipulated to separate the warp yarns into two sets to form a shed therebetween through which a weft yarn is inserted. For one texture pattern, warp yarns are threaded in groups in numbers corresponding to the values of a numerical sequence with a 1/f fluctuation through one set of healds. For another texture pattern, warp yarns are threaded in groups through another set of healds so as to alternate with the first groups, thereby weaving a plural number of texture patterns into the woven goods, with the overall texture design having a 1/f fluctuation.Type: GrantFiled: May 8, 1996Date of Patent: March 17, 1998Assignees: Nisshinbo Industries Inc., Toshimitsu MushaInventors: Toshimitsu Musha, Yuichi Yanai, Shoji Takagi, Shu Ono
