Dyeing composition applicable to weft-knitted fabric

Abstract

The invention discloses a dyeing composition applicable to weft-knitted fabric. The dyeing composition comprises the following raw materials in parts by mass: 5-50 parts of natural plant dye extract, 10-100 parts of disperse dye, 10-60 parts of compound with a cycloparaffin group, 5-15 parts of kieselguhr, 4-10 parts of polyethylene sodium propionate, 6-25 parts of fatty alcohol compound, 5-100 parts of hydrophobic compound, 1-8 parts of dispersing agent, 2-8 parts of water reducing agent and 40-400 parts of water. The dyeing composition is developed according to the structure of the weft-knitted fabric, realizes fast dyeing and high color fastness and avoids frequent color change as well as the phenomena of color dislocation in coloring and non-uniform coloring; and the weft-knitted fabric dyed by the dyeing composition has excellent washing fastness as well as bright and rich colors and is beautiful and elegant after heat setting treatment or softening treatment.

Description

technical field

[0001] The invention relates to printing and dyeing auxiliaries, in particular to a dyeing composition suitable for weft knitted fabrics. Background technique

[0002] Weft knitting is that one or more yarns are sequentially formed into loops by knitting needles along the transverse direction of the fabric at the same time, and are interlaced with each other in the longitudinal direction to form a weft knitted fabric. Due to its special texture structure, weft knitted fabrics are prone to problems such as dyeing dislocation, serious color spots and uneven coloring in the dyeing process of fabrics. On the one hand, the key to solving the dyeing problem is the adjustment of process parameters, and on the other hand, it largely depends on the dyeing ability of the dye and the absorption and penetration performance of the fabric to the dye. At present, there is no dyeing composition specially provided for weft-knitted fabrics with good dyeing effect.
