The invention provides a preparation method of a soft, skin-friendly, non-ironing and washable cotton type knitted fabric. According to the preparation method, the combed cotton yarn which is high in count and suitable for being used as a knitted fabric is preferably selected and matched with the water-soluble PVA polyvinyl alcohol filament to prepare the wrapping yarn, and the PVA polyvinyl alcohol filament can be dissolved in water in boiling and bleaching pretreatment, so that the cotton yarn is in a non-twist fluffy state in the fabric; reasonable pretreatment, liquid ammonia treatment, dyeing and finishing technological processes and technological parameters are optimized, and the problems that in the production process of the knitted fabric, the shrinkage rate is unstable, creases are likely to be generated, deformation is likely to happen, and the color fastness is low are further solved. 本发明提供了一种丝柔亲肤免烫耐洗的棉型针织面料的制备方法。本发明的制备方法优选支数高、适合做针织面料的精梳棉纱，配合水溶性PVA聚乙烯醇长丝制得包缠丝，PVA聚乙烯醇长丝可在煮漂前处理中溶解于水中，使棉纱呈无捻蓬松状态处在织物中；
