Manufacturers of textile auxiliaries and quality inspection laboratories use this standard to evaluate the retarding effect of levelling agents for polyester. By measuring the ability of the agent to slow down the dye uptake of disperse dyes, it helps optimize dyeing processes and ensure uniform coloration of polyester fabrics. This standard is important for improving dyeing quality and reducing color variation in textile production.
纺织染整助剂生产企业和质检机构使用本标准来评估涤用匀染剂的缓染效果。通过测定匀染剂对分散染料上染过程的延缓能力，帮助优化染色工艺，确保涤纶织物染色均匀性。该标准对提高纺织品染色质量、减少色差问题具有重要意义。

This standard specifies the test method for determining the retarding dyeing performance of levelling agents for polyester, applicable to the dyeing process of polyester textiles. The principle involves adding the levelling agent to a disperse dye bath, sampling at specific temperature points during heating, measuring the K/S value of the fabric, and comparing with a blank sample—the greater the difference, the better the retarding effect. The standard details reagents, apparatus, dye liquor preparation, dyeing procedure, and result evaluation, and includes a normative annex for solid content determination.
本标准规定了涤用匀染剂缓染性能的测定方法，适用于涤纶纺织品染色加工。原理是在分散染料染液中加入匀染剂，通过升温过程中特定温度点取样，测试织物K/S值并与空白样对比，差值越大缓染性越好。标准详细列出了试剂材料、仪器设备、染液配制、染色步骤及结果处理要求，并包含含固量测定的规范性附录。

本标准规定了涤用匀染剂缓染性能的试验方法。
通过在分散染料染色工作液中加入涤用匀染剂，在升温过程中的特定温度点进行取样，然后测试取样织物的表观深度K/S值，与不加涤用匀染剂的空白样对比来表征涤用匀染剂的缓染性能。
空白样与加涤用匀染剂后染色织物K/S值的差值越大，表明涤用匀染剂的缓染性能越好。
将涤纶织物投入配好的染液中，控制染色浴比为1:20。
使染浴温度以2.0℃/min的速率升温至80℃，再以0.8℃/min的速率升温至110℃保温10 min，再以3.0℃/min的速率降温至80℃，取出布样，水洗，脱水，置于150℃的热空气中烘燥，烘干为止。
This standard specifies the test method for the retarding dyeing performance of levelling agents for polyester.
By adding the levelling agent for polyester into the disperse dye dyeing liquor, sampling at specific temperature points during the heating process, then testing the apparent depth K/S value of the sampled fabric, and comparing with a blank sample without the levelling agent to characterize the retarding dyeing performance of the levelling agent for polyester.
The greater the difference in K/S value between the blank sample and the fabric dyed with the levelling agent for polyester, the better the retarding dyeing performance of the levelling agent for polyester.
Put the polyester fabric into the prepared dye liquor, controlling the dyeing bath ratio to 1:20.
Raise the dye bath temperature at a rate of 2.0℃/min to 80℃, then at a rate of 0.8℃/min to 110℃ and hold for 10 min, then cool at a rate of 3.0℃/min to 80℃, take out the fabric sample, wash, dewater, and dry in hot air at 150℃ until dry.
