Dyeing properties of PSA/MPIA blended yarn
Abstract
Purpose
The purpose of this paper was to study the dyeing properties of polysulphonamide (PSA)/aramid 1313 (MPIA) blended yarn by selecting suitable dyes and carriers required in the dyeing process.
Design/methodology/approach
Dyeing the blended yarn with cationic dyes, acid dyes, disperse dyes, reactive dyes and pigment, and comparing the shades, K/S values and fastness of the blended yarns.
Findings
The PSA/MPIA blended fibre is suitable for dyeing with the cationic dye at high temperature and pressure in the presence of carrier acetophenone, and good homochromatism is seen on the two fibres when using same type of dye.
Originality/value
PSA fibre is a thermo-resistant and flame-retardant product made in China in recent years. Blended with aramid 1313 fibre, it may acquire good spinnability. But there is little technical report about properties of the blended yarn in the literature at present. This paper reports the dyeing property of such fibres for the first time.
