Polyester Color Fixative DG071

Color fastness characteristics

Polyester color fixing agents have little effect on the hydrophilicity of polyester fibers after dyeing due to their small molecular weight.

Polyester molecules have two hydroxyl groups on the end but no other polar groups, so the hydrophilicity of polyester fibers is relatively poor.

Because polyester fibers are often blended or interwoven with various textile fibers in daily life, there is a certain requirement for the hydrophilicity of polyester fibers after dyeing with color fixing agents.

Performance characteristics

Wide application

It can be used for color fixing treatment of cellulose fibers with direct, reactive, sulphur, acid, dispersed dyes and printed fabrics.

Minimal impact

It does not affect color fastness to light and sunlight, and the hand feel of the fabric remains unchanged after treatment.

Product performance

• Widely used, it can be used for color fixing treatment of cellulose fibers with direct, reactive, sulphur, acid, dispersed dyes and printed fabrics.

• It does not affect color fastness to light and sunlight, and the hand feel of the fabric remains unchanged after treatment.

• Can be used together with cationic silicone oil, softener, etc. in the same bath to reduce operating procedures and production costs.

• It does not affect the original hand feel and hydrophilicity of the fabric, and there is little residual odor on the fabric surface.
