A method for forming a radiation, such as laser, welded point of attachment between at least two fabric pieces, such as ends, is provided. Th e method comprises the steps of lapping the fabric pieces to be attached; applying to the lapped fabric pieces in a region where the fabric pieces are to be attached a radiation, preferably an infrared energy, absorbing ink; and exposing the ink applied region of lapped fabric pieces to a source of radiation in the wave length absorbed by the radiation absorbing ink. In the case of an infrared absorbin g ink, a laser light power has been applied in the range of 200 to 1000 Watts while scanning laser light along the ink applied region at a rate of one to twenty - five meters per minute. The method provides a fabric construction useful as an ai r bag, a gas inflatable safety cushion or curtain or in other applications, su ch as articles of apparel. |
