Embodiment

[0013] The polyester fluffy and soft finishing method of this embodiment includes finishing agent finishing and antistatic agent finishing. The specific method of finishing agent finishing is: using water-dispersible polyester derivative products as polyester fluffy and soft finishing agents, finishing polyester, finishing The concentration of the agent is 3% (o.w.f), the bath ratio is 1:10, soak the polyester in the finishing agent for 20min, and keep the temperature of the finishing agent at 60°C, then take it out and carry out centrifugal dehydration, the liquid carrying rate is 70 %, drying at a temperature of 100°C; finishing with the antistatic agent, the concentration of the finishing agent is 3% (o.w.f), the bath ratio is 1:10, the polyester is soaked in the finishing agent for 20min, and Keep the temperature of the finishing agent at 60°C, then take it out and carry out centrifugal dehydration, the liquid retention rate is 75%, dry it at 110°C for 10 minutes, and final...

Abstract

The invention discloses a polyester fluffy softening finishing method which comprises finishing-agent finishing and antistatic-agent finishing. The finishing-agent finishing particularly adopts the following method: finishing polyester by using a water dispersion polyester derivative product as a polyester fluffy softening finishing agent. In the antistatic-agent finishing, a finishing agent has concentration of 3 percent (o.W.f) and has a bath ratio of 1:10; polyester is soaked in the finishing agent for 20min, the temperature of the finishing agent is kept into 60 DEG C, then the polyester is taken out to be subjected to centrifugal dewatering, the polyester is dried for 10min under the temperature condition of 110 DEG C and finally, the polyester is ironed for 60S to 120S under the temperature condition of 180 DEG C to be sized, wherein a liquid carrying rate is 70 percent to 75 percent. According to the polyester fluffy softening finishing method, crosslinking is carried out on the surface of a fabric to form a film; a cohesive force of fibers is increased; fluff of yarns is reduced; scratchiness is eliminated; a water dispersion polyester component contained in the polyester fluffy softening finishing agent can effectively improve hydrophilicity and antistatic property.

Description

[0001] technical field [0002] The invention belongs to the technical field of fabric treatment, and in particular relates to a fluffy and soft finishing method for polyester. [0003] Background technique [0004] Polyester has the disadvantage of stiff hand feeling. In alkali weight reduction processing, as the weight reduction rate increases, the softness, bulkiness, roughness and crispness of polyester all increase, and the increase in softness is particularly significant. However, polyester is processed through various printing and dyeing processes. If it is not handled properly, the fabric will still become hard and feel rough. Generally, it needs to be improved by mechanical or chemical softening finishing to make the fabric feel soft and smooth. The use of overfeeding can improve the stiffness of polyester caused by mechanical stretching in the printing and dyeing process, and the use of woolen blanket finishing machine or rubber finishing machine can properly impr...
