Abstract

The invention relates to the field of braided belt dyeing technologies, and provides a preparation method for a genuine leather-imitated braided belt which is uniform to dye and not likely to cause color mixing. The preparation method comprises the following steps: (1) pretreatment; (2) dyeing, namely delivering the braided belt pretreated in the step (1) into a dye vat for dyeing, and adding a deepening agent OP-2, wherein the OP-2 comprises polysiloxane emulsion A and polysiloxane emulsion B, the polysiloxane emulsion A comprises 20-25 parts of octamethylcyclotetrasiloxane, 20-25 parts of an emulsifier, and 0.5 part of a catalyst according to weight parts, and the polysiloxane emulsion B comprises 20-25 parts of octamethylcyclotetrasiloxane, 20-25 parts of an emulsifier, and 5 parts of a catalyst according to weight parts; controlling the pressure at 55-65N in the dyeing process; (3) infrared treatment; (4) drying treatment.

Description

technical field [0001] The invention relates to a method for preparing a webbing, in particular to a method for preparing an imitation leather webbing. Background technique [0002] Regarding the definition of ultrafine denier fibers, there is no unified standard in the world. In my country, fibers with a single filament fineness lower than 0.55dtex are usually defined as ultrafine denier fibers. From the perspective of the fiber itself, the main factors affecting the dyeing performance of the fiber are fineness, cross-sectional shape, skin-core structure, crystallinity, orientation degree and polymer content, etc. In addition, it also includes processing conditions before weaving and dyeing and finishing, such as heating temperature, Desizing speed and tension and other factors. Microfiber has the characteristics of fast dyeing speed and high dyeing universality, but due to fast dyeing speed and improper measures, it is easy to cause uneven dyeing, resulting in color diff...
