ABSTRACT OF THE DISCLOSURE A flame-retardant fiber is made comprising 20-95% by weight of amino resin condensate of an amino compound and formaldehyde in which the amino compound may be a melamine, combined melamine and guanamine, combined melamine and urea, combined melamine, guanamine and urea, and benzoguanamine and/or urea, and in which the chemical bond linking the polymer chain is primarily a methylene linkage and 80-5% by weight of polyvinylalcohol, the resulting fiber being cured when necessary and having a tensile strength of at least 1.0 g/d, and having a break elongation of at least 5%. These flame retardant fibers find use in a wide variety of fabrics, either alone or ad- mixed with other fibers. They are particularly useful in the production of flame protective clothing.
