| Abstract: | Cotton samples were pre-treated with various sol solutions containing different alkoxysilanes (TEOS, GPTMS, APTES, and TESP-SA).
The as-prepared cotton samples were dyed with 2 % owf Red and 4 % owf Blue. Furthermore, dyed cotton samples were after-treated
with the alkoxysilanes. The alkoxysilane were also incorporated into the dyeing bath. The as- prepared cotton samples were
subjected to a treatment with the non-formaldehyde durable press finishing agent BTCA in conjunction with the catalyst SHP.
The textile materials were evaluated with respect to the colorimetric data (L*, a*, b*, ΔE*) and the color strength expressed in terms of K/S values. Tensile strength and dry crease recovery angles of the durable pressfinished samples were measured. The findings
indicate that APTES and TESP-SA exert a significant influence on the color properties. |
