Outside bonded thread and Inside bonded thread

The Outside bonded thread is based on the common strands, through the Bonded thread production machine, the sewing thread is heated to dissolve the glue tank, and the Bonding glue wraps the thread on the outside to bond the threads together;

The Inside bonded thread is a process in which a low-melting thermal fuse is added in the middle of the strand during the twisting process. After the heating is set and the hot fuse is melted, the sewing thread is bonded together.
