Abstract: A backup power system according to the present disclosure includes a battery, a charging circuit, power storage, a first load, a second load, and a controller that controls the charging circuit. The controller causes an input current at the charging circuit to increase at a first rate of change in response to a start signal. When the controller detects an increase in a charging voltage at the power storage up to a first voltage at which driving of the first load is possible, the controller controls the charging circuit to cause the input current at the charging circuit to increase at a second rate of change lower than the first rate of change. The charging circuit is controlled by the controller to cause the input current to increase at the second rate of change, and the charging voltage at the power storage increases up to a second voltage at which driving of both the first load and the second load is possible.

Abstract: The topsheet of a absorbent article improved dry feeling, and an evaluation/selection method for a topsheet improved in dry feeling. The liquid-permeable topsheet of a absorbent article, characterized in that a contact cool feeling during a wet condition as measured in a maximum heat transfer quantity (q-max value) is less than 1.1 kw/m2 on the side contacting the skin oft wearer of the topsheet, and a q-max value on the side contacting the absorbent article is larger than a q-max value on the side contacting the skin of a wearer with the difference of at least 0.5 kw/cm2. An evaluation/selection method for the topsheet of a absorbent article excellent in dry feeling using a q-max value during a wet condition as an index.

Abstract: A woven or knit fabric comprising air-jet interlacing spun yarns comprising polyester fibers of low titanium oxide content; a woven or knit fabric comprising air-jet interlacing spun yarns comprising polyester staple fibers obtained by graft polymerization of a hydrophilic compound; a woven or knit fabric comprising air-jet interlacing spun yarns comprising side by side crimped staple fibers; a woven or knit fabric comprising air-jet interlacing spun yarns comprising low-shrinkage staple fibers and copolymerized polyester staple fibers; and a process for producing these. A woven or knit fabric of polyester staple fibers that is bulky, excelling in moisture retention, lightweightness, water absorptivity, quick dryability, etc. and exhibits excellent anti-pilling properties can be obtained.

Abstract: A hydrophilic polyester fiber is supplied with an aqueous mixed dispersion on the surface and made hydrophilic by being heated at 35° C. or higher, and the aqueous mixed dispersion employed contains a polyester-polyether block copolymer composed of a polyester component and a polyether component and is stable at lower than 35° C. and precipitates the polyester-polyether block copolymer when its dispersion state is broken by being heated to 35° C. or higher.

Abstract: A hydrophobic textile product of the present invention is obtained through graft polymerization of an ethylenically unsaturated organic acid. The textile product characterized by: a graft polymerization rate of about 8 wt % or more; substantially no agglutination of a byproduct polymer from the graft polymerization process; a hygroscopicity of about 2.5 wt % or more under a 20° C.×65% RH environment; and an ammonia deodorizing property.

Abstract: A floor mat for livestock, comprising a thermally bonded fiber mat layer having a surface hardness (Durometer hardness) of 60 to 98 by an F-type hardness tester and having a water permeability of not more than 120 seconds.

Abstract: The invention provides a highly stretchable fabric having an elongation percentage of 5 to 45% and a recovery percentage of elongation of at least 70% and comprising spun yarns serving at least as warps or wefts, the fabric being characterized in that the spun yarns contain two-component composite fibers comprising a highly shrinkable polyester component A and a polyester component B less shrinkable than the polyester component A, the composite fibers being so oriented that in the vicinity 5 of the crests of weaving crimps of the spun yarn, the polyester component A faces toward the inner side of the crimps. The invention also provides a process for producing the fabric. The fabric is excellent in stretchability and recovery from elongation and is capable of retaining its appearance and hand.

Abstract: Potential bulky polyester associated bundles or yarns for woven or knitted fabric include spontaneously heat extensible multi-filament A and heat shrinkable multi-filament B. The associated bundles are interlaced at 20-100 interlaces/m. For multi-filament A, the following physical properties apply: <3 denier as a single bundle; 20-80% denier ratio content in associated bundles, wet shrinkage at 100.degree. C. (SHW (A))=0-5%, dry shrinkage at 160.degree. C. (SHD (A))=-15-0%. The properties pertaining to multi-filament B include: fracture tenacity>4 g/denier, denier ratio of 80-29% content in associated bundles, SHW (B)>5-60%. Additionally, SHD (B)-SHD(A)>5%. The invention also relates to processes for forming the bundles and for weaving the bundles into fabric.
