Problems solved by technology
However, there is a problem with dyeing microfibers by the piece dyeing method that it is impossible to dye many colors because microfibers have strong migration properties, so only one color of woven or knitted fabrics can be produced. the fabric
Because it is difficult to grasp the appropriate washing method before dyeing after lightweighting or the appropriate processing conditions during the dyeing process, the method of dyeing after lightweighting has not been tried in the prior art

Embodiment
[0031]Split microfibers made from a composite of 70% polyester and 30% polyamide were twisted to 250tpm. The twisted yarn was wound into a wound yarn on a cheese dyeing machine, and sodium hydroxide was added at 130° C. for 30 minutes to reduce the weight of the yarn by 7%. Iron (Fe)-free water is sprayed onto the lightweight yarn through a spray unit with nozzle injectors to remove foreign impurities. The melted portion of the polyester was removed by applying water pressure. The yarn was then washed by adding sodium hydroxide and treated with acid (RC cleaning agent, product of Hansol Chemical Co., Ltd) to adjust the pH of the yarn to 4.5. Then add black dye (dianix black, Dystar Co., Ltd product), dispersant DC-505 (Korea Shin Kwang Oil Chemical Co., Ltd production), antistatic agent Anol-25B (Korea Shin Kwang Oil Chemical Co., Ltd produced) and softener 3M (produced by ShinKwang Oil Chemical Co., Ltd., Korea) to dye the yarn at 130° C. for 30 minutes. The dyed yarn is t...

The invention relates to a method for dyeing split-type microfibers made of a composite of polyester and polyamide by a yarn dyeing process. The method comprises: a weight reduction step comprising winding the microfibers on a yarn dyeing machine and adding an alkali agent at a uniform temperature of 100-130 DEG C for 30-60 minutes to make a reduction of 6-15% in the weight of the microfibers; a water-washing step comprising injecting iron-free water at 70-80 DEG C onto the microfibers through a nozzle, applying water pressure to remove foreign materials while scouring the microfibers by the addition of a scouring agent, and treating the microfibers with acid to a pH of 4-5; a dyeing step of dyeing the microfibers under pressure by the addition of a dye together with a dispersant, a leveling agent, an antistatic agent and a softening agent; and water-washing and drying the dyed microfibers.
Description
technical field [0001] The invention relates to a method for dyeing microfibers, in particular to a method for yarn dyeing of split-type microfibers made of composite materials of polyester and polyamide. Background technique [0002] Microfibers refer to fibers thinner than once, which have a three-dimensional structure and include countless micro spaces formed when they are split, and thus have excellent water absorption, washing properties, touch and insulation properties. Rags, rugs, towels, nightgowns, etc. made of microfibers enjoy a high reputation due to excellent washability, quick drying, excellent antibacterial and durability, etc. However, in the case of fabrics such as knitwear, fashion socks, etc., which have more effective value by using microfibers, products using microfibers have not yet appeared. This is because microfibers are difficult to dye. [0003] The dyeing method can be divided into a piece dyeing method and a yarn dyeing method performed before ...
