The current invention provides methods provides a novel process to dye polyester/natural fiber blends in an all in one step dyeing process. This all in one step dyeing process is enabled by pre-treatment of the fabric using one or more synthetic cationizing agents. The all in one dyeing is then able to be carried out at a lower temperature and a neutral pH, using a combination of disperse and reactive dyes.

Pigment compositions and fibers may include a single pigment component comprising a cobalt titanium oxide complex or a tin titanium zinc oxide complex. The pigment compositions may additionally include one or more additives having compatibilizer, adhesion promoting, and/or dispersion aiding capabilities, and a carrier resin.

A pretreatment agent of the present disclosure is a pretreatment agent to be applied to a fabric in a region including an ejection region of an ink containing a pigment before the ink is ejected, the pretreatment agent includes a polyvalent metal salt, and the pretreatment agent has a conductivity of 32 mS/cm or more and 49 mS/cm or less.
