Fire retardant mattress with burst-resistant seam

摘要

A mattress resistant to bursting at the seam binding joining the upper and side tickings when subjected to flame conditions, is disclosed. The binding includes a tape overlying the junction of the fabrics defining the top and side tickings. The tape and ticking components are held together by a stitching thread such as lock stitching penetrating the tape, the ticking junctures and the tape again at an opposite side of the binding. The tape is selected to be thermoplastic, fire retardant and flowable at a temperature substantially lower than the char temperature of the thread which is thermo set. As a result of this combination, a flame directed against the binding will first induce the thermoplastic tape to melt and flow around and into the binding thread protecting the thread from charring and consequently losing its tensile strength for a significant period of time.
