Warp beam stamping method for multifunctional aramid fibers

Abstract

The invention discloses a warp beam stamping method for multifunctional aramid fibers. The method comprises the following steps: micronizing a photoinduced light storing type self-lighting material and an anion additive; mixing the functional micro-powder and warp stamping color paste; and performing functional warp stamping process. According to the method, different functional materials with fluorescence and anion are added to the warped flame-retardant aramid warp sheets in the rotary coating screen printing process, thus the aramid warps are multifunctional; the warps and the unprocessed wefts are knitted, so that the flame-retardant aramid stamping fabric has the hazy effect as well as functions such as long-lasting effective caution function, antibacterial function and electromagnetic radiation resisting function. The method can replaces traditional yarn dyeing and finishing technology; a plurality of functional materials are added; the method is applicable to the knitting of various aramid fibers; the finishing process is simple; the stamping and paste coating are combined; water stamping flower is avoided; the energy is saved; and the environment is protected.

Description

technical field

[0001] The invention belongs to the field of functional dyeing and finishing of functional textiles, and in particular relates to a method for warp beam printing of multifunctional aramid fibers. Background technique

[0002] Generally speaking, the functionality of yarn is mainly endowed with functionality through cheese finishing, and cheese finishing is a process for finishing yarn or filament after dyeing. This method is complex in process, high in energy consumption and high in pollution. In the present invention, the aramid fibers with ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, and flame retardant are used to pass through the warp beam printing process, and the aramid yarns are used for winding and twisting and then warping, and the warps are coated and rounded. Screen printing: After printing, sizing, reeding, weaving, and finally desizing, pre-shrinking (untwisting), washing, finishing and finished prod...
