Abstract
Embodiments of the present invention use melamine-based resins as a pretreatment on fabrics and fabric blends in combination with phosphorus-based flame retardants to improve flame retardant performance, durability, and further promote char formation in a combustion zone of the fabric.
Claims21
A flame retardant knit fabric produced by a process comprising:
- applying a melamine-based compound to a fabric comprising nylon wherein applying comprises placing the fabric in a vat of a melamine-based aqueous solution;
- applying a tetrakis (hydroxymethyl) phosphonium (“THP”)-based compound to the fabric;
- and
- fixing the melamine-based compound and THP-based compound as a flame retardant in the fabric.
1 more element
A flame retardant fabric comprising 52 percent or less nylon, and a halogen-free flame retardant comprising a THP-based compound on the nylon.
A flame retardant fabric comprising:
- a fabric comprising a cotton and a nylon blend;
- and
- a flame retardant composition on the fabric, wherein the flame retardant composition comprises a melamine-based compound and a THP-based compound.
