Reactive Printing and Wash Fastness of Inherent Flame Retardant Fabrics for Dual Use

Abstract

The possibility of reactive printability on protective flame—resistant fabrics, varied in composition of weft threads and weave was investigated. In addition, the wash fastness of printed samples was analyzed. The functional properties of fabrics were assessed by measuring of the Limiting Oxygen Index (LOI). Printing was performed with two printing pastes varied in thickeners and two dyestuff concentrations. The samples were analyzed by microscopic imaging using digital microscope and spectrophotometric measurement before and after the five washing cycles. The results confirmed the printability of FR inherent fabrics specified through fine colored effects and optimal wash fastness.

“…In this scenario, among others, organophosphorus compounds, such as tetrakis (hydroxymethyl) phosphonium chloride (THPC), hydroxyl functional organophosphorus oligomer (HFPO), as well as N-alkyl-substituted phosphono-propionamide derivatives, have been largely used on the market, dramatically increasing the number of applications for cellulose-based flame-retardant textiles [8,28].…”

Flame retardancy and aspects of the vat dyes application on inherently flame retardant fabrics

“…In general, in the field of research on the protective properties of textiles, two directions are being developed in the context of flame resistance. The first involves the development of various preand after treatment methods that give textiles flame resistance properties and which began to be developed in the first half of the 18 th century, while the second is a more recent direction and involves the development of inherently flame resistant fibres, yarns and fabrics [1,2]. Inherent flame retardancy can be achieved in conventional synthetic fibres by incorporating fire retardants into the polymer structure during production -melting and extrusion, or by copolymer modification before, during and after the production of filament or staple fibres [3].…”

Application issue of anthraquinonoid vat dyes on inherently flame‐resistant fabrics

“…Thermostable fibres are highly complex for dyeing involving numerous difficulties arising from their chemical structure such as the high degree of orientation of the macromolecules in the polymer chain, high crystallinity and density as well as pronounced intrinsic colouring. The meta/para aramid fibre are practically non‐dyeable in classic dyeing and printing procedures, after spinning, and the fibre itself has a pronounced yellow‐green colour which causes additional difficulties in dyeing 14,15 . Given the problematic nature of the application of traditional dyeing techniques, the literature finds research on the application of some treatments or process modifications 14,16–22 .…”
