THREE-DIMENSIONAL FABRIC

摘要

PURPOSE: To form a good continuous cylindrical shape, secure high impact resilience, remarkably improve tensile strength and attain remarkable shortage of heat-treating time by constituting a fabric in continuous cylinder by dry heat restriction shrinkage treatment using a highly shrinkable yarn. CONSTITUTION: Upper and lower ground structures 3 and 3 in which warp 1 and weft 2 are constituted by plane weave or doup weave are provided and highly shrinkable yarn 4 having >=30% shrinkage factor is arranged at prescribed interval in the warp direction or weft direction between upper and lower ground structures 3 and 3 and a mixed weave 4c binding highly shrinkage yarn 4 to ground structure 3 is formed in single fabric part and an intermediate float yarn 4d in which the highly shrinkable yarn 4 and the ground structure 3 are unbound is formed in double fabric part to constitute a mixed fabric and the mixed fabric is subjected to dry heat restriction shrinkage treatment to form the fabric of continuous cylindrical structure.
