The invention relates to a high temperature resistant
nylon fiber for manufacturing wig and a preparation method thereof. The
fiber is prepared from the following raw materials in parts by weight: 100parts of PA nylon slice, 1 to 10 parts of additive, 0.1 to 10 parts of
pigment, and 0.1 to 5 parts of dispersed
wax, wherein the additive is at least one of
calcium carbonate, talcum
powder, titaniumdioxide,
silicon dioxide, diatomite, silica
powder, glass bead and
mica powder, and the temperature resistant range of the
pigment is 180 to 350 DEG C. The preparation method comprises the followingsteps: step a,
drying raw materials; step b, carrying out single screw
extrusion; step c, cooling nascent fibers; step d, applying oil; and step e, carrying out thermal setting and packaging. The prepared
fiber is very smooth and has excellent breathability, good
moisture removing performance, and unique and natural luster, which is like the luster of real human hair. Moreover, the environment isnot polluted during the preparation process, and no
wastewater or waste is generated.
