Abstract
[Problem] The objective of the present invention is to provide an elastic mesh structure having exceptional cushioning and reducing noise during compression or recovery. [Solution] A mesh structure comprising a three-dimensional, random-loop, joining structure formed by winding a continuous line of thermoplastic resin to form random loops, bringing the loops into contact with one another in a molten state, and fusing the majority of the contact area, wherein (a) the apparent density of the random-loop contact structure is 0.005-0.200 g/cm3, and (b) the number of contact points per unit weight of the random-loop contact structure is 500-1200/g.
Claims14
A network structure comprising a random loop bonded structure of a continuous linear structure of a thermoplastic resin, wherein (a) the random loop bonded structure has an apparent density of 0.005 to 0.200 g/cm3 and (b) a number of bonded points per unit weight of the random loop bonded structure is 500 to 1200/gram.
