By adding the additive into the polypropylene raw material, the fluidity of the melt can be effectively improved, and the fine denier staple fiber of 0.6-0.8 d is prepared after melt spinning. Due to the geometrical property, the surface effect, the gloss effect and the mechanical property after the fine denier, the defects of poor hand feeling, wax feeling, poor moisture absorption and the like of the original fiber are changed, the fiber has very soft hand feeling, soft gloss and excellent moisture absorption and sweat conductivity, and the fine finishing can be realized by means of washing fixation and the like after the dyeing of the cotton fiber, wherein the fixation refers to that cationic dye is used as a fixation agent for dyeing real silk by water-soluble dye, and the coulomb fixation is usually completed by means of gravitation. When the anionic dye dyes the fiber, the surface charge of the fiber is increased and is distributed randomly. The conductivity measurement result shows that under the condition of same molecular weight, the charge quantity of anionic dye is generally lower than that of cationic dye, if the dye quantity dyed on the fibre is fixed, the negative charge quantity on the fibre is fixed, at this time, if the total charge quantity of the added cationic dye is equal to that of the cationic dye, the optimum colour-fixing effect can be obtained.
The traditional dyeing method of the cotton fabric is mainly traditional dip dyeing, a large amount of dyes are usually needed for dip dyeing, most of the dyes are acid dyes or neutral dyes, and the dyes usually contain a large amount of harmful substances and organic matters, so that a large amount of dye-rich wastewater is formed in the dyeing process of the cotton fabric, and therefore a large amount of cost needs to be invested to treat the dye wastewater, and the economic benefit of the dyeing of the cotton fabric is influenced.
