Polyester preparation process

The invention relates to fabric processing, in particular to a polyester preparation process which comprises the following steps: S1, performing deoiling treatment on a polyester fabric to be deoiled in a soaking manner; s2, dyeing the polyester fabric in a soaking manner; s3, cooling and color fixing are conducted on the polyester fabric; s4, cleaning the polyester fabric; in the process, a processing pool, an in-pool frame group and a plurality of roller assemblies arranged on the in-pool frame group from top to bottom are used, and any two adjacent roller assemblies are staggered in the left-right direction, so that the mechanical action borne by polyester during dyeing and cleaning can be reduced. 本发明涉及织物加工，更具体的说是一种涤纶制备工艺，包括以下步骤：S1、将待除油的涤纶织物采用浸泡式的方式去油处理；S2、将涤纶织物采用浸泡式的方式染色；S3、对涤纶织物降温定色；S4、清洗涤纶织物；在过程中使用加工池，以及池内架组，以及由上至下设置在池内架组上的多个辊子组件，任意两个相邻的滚子组件在左右方向错开设置，目的是可以降低涤纶在染色和清洗下所受的机械作用。
