Preparation method of non-silicon antistatic hydrophilic fluffy softening finishing agent

The invention discloses a preparation method of a non-silicon antistatic hydrophilic fluffy softening finishing agent. The preparation method includes the steps: (1) selecting synthetic raw materials:selecting polyethylene terephthalate and polyethylene glycol with the weight ratio of (60-80):(20-40); (2) taking catalysts: setting the dosage of the catalysts accounting for 0.1%-0.5% of the totalweight of the polyethylene terephthalate and the polyethylene glycol; (3) placing the raw materials and the catalysts into a container once, and performing reaction under the condition of the temperature of 240-280 DEG C for 2-4 hours. By the aid of the polyethylene terephthalate, the polyethylene glycol and the catalysts, the finishing agent can be synthesized only by a one-step method and is high in conversion rate capable of reaching 98% or more and high in purity, and the use ratio of the finishing agent is effectively increased. When in use, the finishing agent can be thawed by cold waterwithout hot water, and los
