Polyester yarn with good pilling resistance and dyeing property and preparation method thereof

The invention discloses a polyester yarn with pilling resistance and good dyeing property. The composite material is prepared from the following raw materials in parts by weight: 50-60 parts of polyethylene glycol terephthalate, 20-27 parts of polyhexamethylene dodecanamide, 10-15 parts of seaweed modified viscose, 6-9 parts of maleic anhydride grafted polyolefin elastomer, 2.5-3.5 parts of sodium dodecyl benzene sulfonate, 3-4 parts of polyaluminum chloride, 4-6 parts of a composite lubricant, 5-7 parts of silicon dioxide, 2.5-3.5 parts of an anti-ultraviolet agent, 2.5-3.5 parts of an antioxidant and 3-4 parts of a heat stabilizer. The anti-pilling polyester yarn with good pilling resistance and dyeing property is high in anti-pilling grade and excellent in anti-pilling property; the wear-resistant frequency is high; the volume resistivity is small, and the antistatic performance is good; the dyeing property is good, and the comprehensive performance is good. 本发明公开了一种耐起球、染色性好的涤纶纱线，由包括以下重量份的原料制成：聚对苯二甲酸乙二醇酯50
