The invention belongs to the technical field of down jacket manufacturing, and discloses a down jacket floating
yarn liner glue brushing type semi-
laser bag manufacturing method which comprises the following steps: S1, bonding a layer of fusible
interlining at a reserved pocket of a
smooth surface of floating
yarn liner cloth, pre-pressing a second layer of double faced
adhesive tape at the reserved pocket, and installing a circle of fixing line outside the double faced
adhesive tape and away from the outer ring of the double faced
adhesive tape; s2, a first layer of double-faced adhesive tape is pre-pressed on a reserved pocket of the glue brushing face of the floating
yarn liner cloth, surface cloth is laid on the glue brushing face and aligned, and the floating yarn liner cloth and the surface cloth are bonded through a bonding
machine; s3,
laser is conducted at the reserved pocket, sewing is conducted at the position away from the
laser edge, and the two sides of the zipper code belt are connected with the floating yarn liner cloth and the shell fabric respectively; and S4, flat pressing is conducted through a
hot press. In the whole production process, the bonding stability of the fabric and the floating yarn liner cloth and the accuracy of
laser processing are both considered, the fabric, the floating yarn liner cloth, the fusible
interlining and the double-faced adhesive tape can be effectively bonded, and the laser bag is reinforced in combination with semi-
laser cutting treatment.
