The invention provides a heat-shrinkable polyester-based film containing 90 mol % or more of ethylene terephthalate unit based on 100 mol % of whole ester unit, wherein at least a part of ethylene glycol and/or terephthalic acid constituting the ethylene terephthalate unit is derived from biomass resource or the heat-shrinkable polyester-based film contains polyester resin recycled from PET bottles, and the heat-shrinkable polyester-based film satisfies the requirements: (1) heat-shrinkage ratio in a width direction measured by shrinking the film for 10 seconds in 90 C. hot water is 50%-75%, (2) heat-shrinkage ratio in a longitudinal direction measured by shrinking the film for 10 seconds in 90 C. hot water is 6% or more and 14% or less, (3) heat-shrinkage ratio in the longitudinal direction measured by shrinking the film for 10 seconds in 70 C. hot water is 6% or more and 6% or less, and (4) irregularity of thickness in the width direction is 1%-20%.

The present invention provides an apparatus for producing and putting on gloves capable of producing gloves that fit an individual hand shape and also putting the glove on the hands, and a method for producing and putting on gloves. The apparatus for producing and putting on gloves comprises welding and cutting means which welds and cuts a first elastic film and a second elastic film at a position on the outer side of a contour of a user's hand in a state in which the user's hand is sandwiched between the first elastic film and the second elastic film.

A heat shrinkable film and a process for regenerating a polyester container using the same. The heat shrinkable film comprises a copolymerized polyester resin comprising a diol component and a dicarboxylic acid component and has a heat shrinkage rate of 30% or more in the main shrinkage direction upon thermal treatment at a temperature of 80 C. for 10 seconds and a melting point of 190 C. or higher as measured by differential scanning calorimetry. It not only solves the environmental problems by improving the recyclability of the polyester container, but also is capable of enhancing the yield and productivity.

The combination of 3D printing technology plus the additional dimension of transformation over time of the printed object is referred to herein as 4D printing technology. Particular arrangements of the additive manufacturing material(s) used in the 3D printing process can create a printed 3D object that transforms over time from a first, printed shape to a second, predetermined shape.

A process produces a tubular hybrid molding made of a plastics foam element that exhibits temperature-dependent shrinkage and a fiber-plastics composite. The method includes inserting the plastics foam element, unhardened first and second fiber-plastics composite sections into a mold, where the plastics foam element has open pores at locations in contact with the fiber-plastics composite. The plastics foam element and the fiber-plastics composite sections are shaped by the mold. The mold is exposed to a first temperature to minimize the viscosity of the resin in the fiber-plastics composite. The mold is exposed to a second temperature to harden the fiber-plastics composite and to achieve mechanical fixing of the plastics foam element thereon. The mold is exposed to a third temperature to shrink the plastics foam element and cause its shape to conform to that of the mold and achieve a final shape of the said element.
