  • Process for manufacture of closed end mops
    Patent number: 4811989
    Abstract: Mops and process for making closed or uncut end mops particularly using single ply cotton yarn having a high degree of twist. The yarn is processed through a fringe making machine into lengths of pre-sewn fringe and the high twist yarn tends to bunch together in thick, ropy masses of yarn strands. The fringe is affixed to mop backs to form a mop, and the mops are then soaked in a high temperature water bath until the ropy yarn strands relax, straighten and separate. The mops are rinsed and transferred to a high temperature hot air dryer and dried until the separate yarn strands twist about their looped ends to form separate, individual doubled ply yarn strands with uncut ends.
