摘要： With regard to a care bed provided with a three-dimensional net-like structure made of a thermoplastic resin, an object is to smoothly bend the three-dimensional net-like structure in multiple stages in response to a complicated motion of a bed main body or a user's specific motion. A three-dimensional net-like structure 101 includes a first three-dimensional sparse/ dense structure 1 provided as an alternately layered configuration of structural units 1a 1 to 1a 9 that are sparse in an extrusion direction Y and structural units 1b 1 to 1b 8 that are dense in the extrusion direction Y. In this first three-dimensional sparse/ dense structure 1, a bulk density δ 1 of the sparse structural units 1a 1 to 1a 9 is 0.01 to 0.08 g/cm 3 and a bulk density δ 2 of the dense structural units 1b 1 to 1b 8 is 0.03 to 0.10 g/cm 3 . A ratio δ 2 / δ 1 of the bulk density of the dense structural units 1b 1 to 1b 8 to the bulk density of the sparse structural units 1a 1 to 1a 9 is 1.01 to 5. A length A 1 of the sparse structural units 1a 1 to 1a 9 is 1 to 50 cm, and a length A 2 of the dense structural units 1b 1 to 1b 8 is 3 to 60cm. A ratio A 2 /A 1 of the length of the dense structural units 1b 1 to 1b 8 to the length of the sparse structural units 1a 1 to 1a 9 is 0.1 to 10.

摘要： The object is to improve the production efficiency of three-dimensional net-like structures while maintaining the surface quality of the three-dimensional net-like structures. A second chute 6 is located below a hole-free region 33 and is provided between first chutes 4a and 4b. Filaments 20a and 20b located on longitudinal sides 22b and 22c at the periphery of assemblies 21a and 21b are in contact with the upper side of inclined surfaces 46a and 46b of the second chute 6 and inclined surfaces 46a and 46b of the second chute 6. Such contact disturbs the vertical fall of the filaments 20a and 20b and causes the filaments 20a and 20b to be tangled in loops with the adjacent filaments 20a and 20b and pass through the first chutes 4a and 4b and the second chute 46a and 46b, while being cooled down with water supplied from openings 51a, 51b and 51c.

摘要： By taking into account the difficulty in smoothly bending along the shape of, for example, a care bed, there is provided a three-dimensional net-like structure made from polyester having a swelling ratio dependent on a shear rate such as to be 1.10 to 1.38 at a shear rate of 60.8 sec -1 and 1.17 to 1.43 at a shear rate of 608 sec -1 and having an MFR of 3 to 35 g/ 10 min and a density of 1.01 to 1.60 g/cm 3 and configured to have a spring structure of filaments randomly brought into contact with and tangled with one another, have a three-dimensional striped sparse-dense configuration in a lateral direction relative to an extrusion direction. The swelling ratio is shown as D 2 /D 1 against shear rate when a molten thermoplastic resin is extruded to filaments from a capillary having a tube inner diameter D 1 of 1.0 mmÆ and a length of 10 mm and D 2 denotes a diameter of cross section of the filaments extruded and cooled down.

摘要： Framework-like structures suffer from a problem in that transport costs are increased because bulk density is low. A mattress (1) composed of a framework-like structure is placed in a bag (2) for compression, a zipper of the bag (2) for compression is closed, a suction port of a suction device such as a vacuum cleaner is brought into contact with a non-return valve and air is suctioned out to thereby place and seal the mattress, which is in a compressed state, in a vacuum state and compress the thickness of the mattress (1). An airtight state at 65°C is subsequently maintained inside a container during transport. After transport, the zipper of the bag (2) for compression is opened, and the mattress (1) having been extracted from the bag (2) for compression is placed in a hot-air tank and restored in an atmosphere of 85°C.
