| 摘要 |
The invention relates to a method for producing a ductile, elastic non-woven fabric based on polyester fiber and having a high-shrinkage material component, the fiber mixture being in solution and laid out in a carding engine to form the fabric, said fabric having transverse and longitudinal connection of fibers, the polyester fibers being subsequently fixed. According to the invention, the solidified fabric is fed quickly through a tensioning frame with slack, and there exposed to a further or additional temperature treatment, in order to initiate the shrinking process of the high-shrinkage material component, resulting in loss of surface area and crinkling of the non-woven fabric, so that the desired elasticity is obtained in the material in both the longitudinal and transverse directions. |
