Abstract

The invention discloses a pad dyeing technology of a super-imitated cotton / cotton blended fabric. The pad dyeing technology particularly comprises the following steps: firstly, carrying out light alkali desizing treatment on the super-imitated cotton / cotton blended fabric; and then sequentially carrying out low-alkaline mercerizing, presetting and dyeing, thereby finishing dyeing of the fabric. By a one-bath pad dyeing technology of disperse / reactive dyes, continuous and mass production of a product can be achieved; the problem that a traditional overflow dyeing technology can only be applied to intermittent small-batch production is solved; the production efficiency is improved; and the dyelot chromatism is reduced. Dyeing is carried out by the technology disclosed by the invention, so that the damage to a super-imitated cotton fiber is small; the mass per unit area and the breaking strength loss of a finished fabric product are small; and the processed fabric is bright and full in color, high in color fastness and good in hand feeling and wearing comfort. Compared with a conventional pad dyeing technology, the pad dyeing technology is low in alkali charge, low in dyeing temperature, low in energy consumption, energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of textile chemistry, and relates to a pad dyeing process of a super imitation cotton / cotton blended fabric. Background technique [0002] Super-imitation cotton fiber is a new type of functional simulation fiber developed during my country's "Twelfth Five-Year Plan". It uses polyester fiber as the main raw material and integrates polymerization, spinning, weaving, dyeing and finishing technologies. Through physical modification and chemical modification The method makes the fiber have both the advantages of polyester fiber and cotton fiber. It not only has the good hand feeling, soft comfort and hygroscopicity of cotton fiber, but also has the mechanical properties, moisture permeability, wrinkle resistance, heat resistance and heat resistance of polyester fiber. Good color fastness. Constrained by cotton production and prices, as well as the dual impact of overcapacity of ordinary polyester fibers, super-im...
