Title: Manufacture of futon mat
Inventor: KUNIEDA YOSHIO
IPC: A47C27/12
Filed: 1994-06-23
Abstract: PURPOSE:To provide a manufacturing method of a futon mat which enables the preventing accurately ticks from entering by stopping sewing holes formed with a sewing machine. CONSTITUTION:The surface portion 1 and the rear portion 2 of side fabric are sewn together with a sewing machine using a sewing thread 3. The sewing thread 3 used has the surface of the thread to be used for normal sewing of cotton or the like coated with a synthetic resin meltable easily by heat, for example, polyester. Then, stitch parts sewn is subjected to pressurizing and heating treatments. When heat is applied to the stitches, polyester applied on the sewing thread 3 melts and permeates into the side of sewing holes 4. Under such a condition, when heating is halted, temperature lowers naturally and the polyester permeated into the sewing holes 4 is solidified closing the sewing holes 4 thereby enabling the preventing ticks from entering from the sewing holes 4 accurately.
