Provided is a shoe including an upper composed of a fiber sheet, the fiber sheet including: a base sheet including yarns having heat shrinkability; and a plurality of chip members, each of which is a sheet having an area smaller than that of the base sheet, the base sheet and the plurality of chip members being layered and joined together.

What is provided is a heat-shrinkable film and a heat-shrinkable label that, when applied to a container in which the difference between the diameter of the body portion and the diameter of the mouth portion is large, sufficiently shrink in the mouth portion and do not easily allow the generation of a wrinkle or a sink mark in the mouth portion. The heat-shrinkable film contains polyester, a dicarboxylic acid component that constitutes the polyester contains 95 mol % or more of terephthalic acid, and a diol component that constitutes the polyester contains 50 mol % or more of ethylene glycol and 15 mol % or more of cyclohexanedimethanol. The shrinkage rate in the primary shrinkage direction when the heat-shrinkable film is immersed in hot water at 70 C. for 30 seconds is 20% or less, the shrinkage rate in the primary shrinkage direction when the heat-shrinkable film is immersed in hot water at 80 C. for 30 seconds is 45% to 65%, and the shrinkage rate in the primary shrinkage direction when the heat-shrinkable film is immersed in hot water at 98 C. for 30 seconds is 65% or more.

The invention provides a nonwoven laminate, comprising in order (A) to (E): a spunbond nonwoven layer (A) comprising fibres, which comprise polyethylene terephthalate (PET) and copolyester; an optional spunbond nonwoven layer (B) comprising fibres, which comprise polyethylene terephthalate (PET) and copolyester, the nonwoven layer (B) having a higher copolyester content than nonwoven layer (A); a needled staple fibre nonwoven layer (C), comprising: monocomponent polyethylene terephthalate (PET) staple fibres (c1), and multicomponent staple fibres (c2), which comprise at least a polyethylene terephthalate (PET) component and a copolyester component; an optional spunbond nonwoven layer (D) comprising fibres, which comprise polyethylene terephthalate (PET) and copolyester, the nonwoven layer (D) having a higher copolyester content than nonwoven layer (E); a spunbond nonwoven layer (E) comprising fibres, which comprise polyethylene terephthalate (PET) and copolyester; wherein all layers are melt-bonded to each other.

A radiative cooling film and a product thereof are provided. The radiative cooling film includes a carrier layer, a reflective layer and an emissive layer stacked together. A light shines on the radiative cooling film from the emissive layer. The emissive layer includes a polymer containing a CF bond. The carrier layer includes a polymer containing at least one of a CC bond and a CO bond. After disposing at 120 degrees centigrade for 30 minutes, a transverse direction heat-shrinkage rate of the carrier layer is less than or equal to 2%, and a machine direction heat-shrinkage rate of the carrier layer is less than or equal to 3%. A thickness of the radiative cooling film is in a range of 50 m to 170 m, and a thickness of the emissive layer accounts for 20% to 90% of the thickness of the radiative cooling film.
