Patent number: 11834779Abstract: Functional agent-containing fibers according to an embodiment of the present invention, wherein a functional agent is supported by silicone fixed to the fibers. The silicone includes an acrylic-modified organopolysiloxane having two or more acrylic groups per molecule. A rate of decrease in the functional agent after the functional agent-containing fibers are washed 10 times is less than 40%. In the present invention, the functional agent-containing fibers may be produced, e.g., by irradiating fibers impregnated with a fiber treatment agent A containing silicone with an electron beam so that the silicone is fixed to the fibers, and impregnating the fibers to which the silicone has been fixed with a fiber treatment agent B containing a functional agent. The functional agent-containing fibers may be produced, e.g.Type: GrantFiled: March 26, 2018Date of Patent: December 5, 2023Assignees: SHIN-ETSU CHEMICAL CO., LTD., KURASHIKI BOSEKI KABUSHIKI KAISHAInventors: Shinji Irifune, Tomoya Kanai, Masaki Tanaka, Minoru Sugiyama, Hidenobu Morishima, Kazuhiro Sato

Publication number: 20230172831Abstract: A cosmetic containing at least one organosiloxane represented by general formula (1), having a boiling point in a range of 205 to 255° C. and a viscosity of less than 5 mm 2/s at 25° C. In the formula, R's are identical to or different from one another and each independently represent a hydrogen group, hydroxy group, or a monovalent hydrocarbon group having 1 to 3 carbon atoms, but at least one R is a monovalent hydrocarbon group having 2 to 3 carbon atoms. “a” represents 1 to 5. Thus, a cosmetic which has light touch, good spread, and excellent water repellency, forms uniform cosmetic film, and successfully achieves favorable feeling on use with no strong oily feeling, and which has excellent stability over time and cosmetic persistence even when blended with various oil agents, such as silicone, hydrocarbon oil, and ester, an organic ultraviolet absorber, or an oily component solid at 25° C.Type: ApplicationFiled: April 14, 2021Publication date: June 8, 2023Applicant: SHIN-ETSU CHEMICAL CO., LTD.Inventors: Hiroko KIKUCHI, Akiko MIZUNO, Sachie YANAGIDA, Tomoya KANAI, Takuya ABE, Ryunosuke HATA

Publication number: 20200040520Abstract: In one embodiment, the present invention relates to silicone-fixed fibers including fibers and silicone fixed to the fibers. The silicone includes an acrylic-modified organopolysiloxane (A) having two or more acrylic groups per molecule. A rate of decrease in the amount of Si after the silicone-fixed fibers are washed 10 times is less than 50%. The present invention relates to a method for producing silicone-fixed fibers. The method includes coating or impregnating the fibers with a fiber treatment agent containing silicone, and irradiating the fibers coated or impregnated with the fiber treatment agent with an electron beam so that the silicone is fixed to the fibers. The silicone includes an acrylic-modified organopolysiloxane (A) having two or more acrylic groups per molecule. Thus, the present invention provides silicone-fixed fibers that include fibers to which silicone is fixed by electron beam irradiation and have a good texture even after washing, and a method for producing the silicone-fixed fibers.Type: ApplicationFiled: March 16, 2018Publication date: February 6, 2020Inventors: Shinji IRIFUNE, Tomoya KANAI, Masaki TANAKA, Minoru SUGIYAMA, Kunihiro OHSHIMA

Patent number: 10421840Abstract: Disclosed herein is a silicone-modified polyimide resin composition of solvent free type. The composition is suitable for use as an adhesive and a coating material which are capable of hardening upon irradiation with ultraviolet rays and/or visible rays. Also, it is saved from drooling even in the case of light filling with an inorganic compound and it is saved from bubble entrapment and nonuniformity at the time of application with heavy filling. It further exhibits good moldability due to its thixotropic properties. Moreover, it exhibits improved adhesion to polyolefin resins without impairing the past properties. Finally, it gives rise to a cured product which is not excessively hard, with a low elastic modulus, despite filling with an inorganic compound. The composition of the present invention includes components (A) to (B) listed below and is characterized by being fluid at 25° C.Type: GrantFiled: June 13, 2017Date of Patent: September 24, 2019Assignee: SHIN-ETSU CHEMICAL CO., LTD.Inventors: Hatsuhiko Hattori, Yoshinori Yoneda, Tomoya Kanai
