Special Finishing of Cotton to Impart Flame-Retardancy, Easy Care Finishing and Antimicrobial Properties

Abstract

Reactive amine-amide derivatives are prepared via the addition reaction of different primary and secondary amines on acrylamide (AAm) using equivalent molar ratios and the resultant product is methylolated using equivalent amounts of HCHO. Bis (hydroxymethyl carbamoylethyl) ethylamine (I), tetra (hydroxymethyl carbamoyl ethyl) ethylene diamine (II) and penta (hydroxymethyl carbamoylethyl) diethylenetriamine (III) are prepared by reaction between ethylamine or ethylenediamine or diethylenetriamine and AAm. N-Hydroxydiethyl-phosphonopropianamide (IV) is prepared via Mecheal addition reaction of diethylphosphite with AAm followed by reaction with HCHO. To impact flame-retardancy and easy care finishing to cotton fabric aqueous formulations of compound IV, etherified methylolated melamine (EMM) and/or compounds III, II or I have been prepared. Cotton fabric treated by pad–dry–cure system, the drying time was investigated. Cured cotton fabrics are fire retardant if the aqueous formulation contains 12 % w/w of compound IV and 6 % w/w of EMM respectively. Physical and mechanical properties are less deteriorated when compound III, II or I are used instead of EMM and the liberated HCHO is almost decreased to one half by replacing EMM by one of the prepared methylol compounds. Treatments with compounds III, II or I is impart antibacterial and antifungus properties to the finished fabric.

Cenospheres and their application advantages in biomedical engineering - a systematic review

“…Cellulose fibres are natural polymers used to make dressings; therefore, the high performance of the natural fibre properties should be enhanced. There are several ways to functionalize natural fibres, such as by deposition or infiltration of functional polymeric materials on or into the surface of the fibres using nanotechnology still while maintaining the fibre properties [87][88][89][90][91][92][93][94][95][96][97][98][99][100][101][102]. Silver has for many years been used to treat various ailments or to prevent the transmission of infections [103].…”

Novel flame retardant and antibacterial agent containing MgO NPs, phosphorus, nitrogen and silicon units for functionalise cotton fabrics

“…The mechanism of amino and silicon unit as antibacterial agents was reported before, that is each of them can bound to cell membrane of the bacteria to disturb it and to inhibits their growth due to leakage of intracellular components [40][41][42][43][44][45].…”

Preparation of nano disperse dye based on benzopyran in one pot reaction using microwave irradiation and its appliance in textile printing

“…Perkin Elmer double-beam spectrophotometer is used to measure Absorption spectra. Colour strength values of the dyed fabrics was measured using reflection spectroscopy (Hunter Lab UltraS-canPRO USA, 2007) at the wavelength of the maximum absorbance and it was expressed as K/S which assessed by applying the Kubelka-Munk equation [6,7,22,24,25,45,46]. Fastness properties of dyed fabric to washing, crocking (dry and wet rubbing), perspiration and light were determined according to standard methods AATCC…”
