Abstract

Purpose

The purpose of this paper is to investigate the effect of self‐emulsifying polysiloxanes containing multi‐cationic groups as resin on fastness properties of dyed cellulose fabrics.

Design/methodology/approach

Cellulose fabrics were dyed with three reactive dyes. Then, the self‐emulsifying polysiloxanes containing multi‐cationic groups as resin were applied to the dyed cellulose fabrics. The fastness properties were investigated.

Findings

The results show that the wet rubbing fastness, washing fastness and perspiration fastness of three dyed samples treated with novel self‐emulsifying polysiloxanes are higher than those of the dyed samples without the polymer treatment. The complexes of cellulose with the polysiloxanes having multi‐cationic groups are formed. With the increase of the quantity of cationic groups in the polymer macromolecules, the wet rubbing and washing fastness further increase. The self‐emulsifying polysiloxanes can affect the colour yields (K/S) of the dyed fabrics.

Originality/value

The self‐emulsifying polysiloxanes containing multi‐cationic groups are novel functional materials. They are easily self‐emulsifying in water, without the need of disperse agents, and form a transparent macromolecule colloid solution. Self‐emulsifying polysiloxanes as resins can change material properties to improve their wet fastness and gloss. They have potential application as resins in the coloration industry. This paper is an original research report and has not been published previously.
