Summary: | PURPOSE:To provide the ball wadding for padding with which blowing workability is easy and the uniform wadding is obtainable and which is made into the padding having an excellent property to restore elasticity by a heat treatment. CONSTITUTION:This ball wadding is constituted of the short fibers which are composite fibers of >=6d single fiber fineness formed by eccentrically joining a copolymer polyester A consisting essentially of ethylene terephthalate unit copolymerized with 1.5 to 6mol% constituting unit having a metal salt sulfonate group and polyethylene terephthalate B, have latent crimpability to develop >=30 pieces/25mm spiral crimps when subjected to a free shrinkage heat treatment for 10 minutes at 180 deg.C and are imparted with 8 to 20 pieces/25mm mechanical crimps. The crimped parts entangle with each other to form a ball shape of 3 to 20mm diameter. |
