Abstract

The invention provides a printing method of an aramid-viscose blended camouflage printed fabric. The method comprises the following step of carrying out pretreatment, dyeing, pigment printing and after treatment on an aramid-viscose blended fabric in sequence to obtain the aramid-viscose blended camouflage printed fabric, wherein a dye liquor for dyeing contains 2g / L to 5g / L of vat olive T, 3g / L to 7g / L of vat brown G and 4g / L to 8g / L of vat yellow G; a color paste for pigment printing contains 1g / L to 4g / L of paint red, 0-3g / L of paint yellow, 1g / L to 4g / L of paint purple and 1g / L to 3g / L of paint green. According to the invention, vat dye dyeing, paint printing and after treatment are performed under specific conditions so that the aramid-viscose blended camouflage printed fabric is high in color fastness and beneficial to application.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a printing method of an aramid viscose blended camouflage printed fabric. Background technique [0002] Aramid fiber refers to the fiber material spun from the polymer obtained by polycondensation reaction of aromatic diamine and aromatic dicarboxylic acid or aromatic aminobenzoic acid, which belongs to aromatic polyamide fiber. At present, the main varieties of aramid fibers are aramid 1313, aramid 1414 and aramid 14, etc., among which, the chemical name of aramid 1313 is polyisophthalamide m-phenylenediamine fiber, and the chemical name of aramid 1414 is poly P-phenylene terephthalamide fibers. Due to its special structure, aramid has excellent high temperature resistance and flame retardancy, and can be used as a flame-retardant fabric. In order to further improve the performance of aramid fabrics, aramid and viscose fibers can be blended. The resulting aramid viscose blen...
