Manufacturers of textile auxiliaries and quality inspection agencies use this standard to evaluate the performance of cotton fixing agents. By measuring the improvement in color fastness and the degree of color change before and after fixation, the actual effectiveness of the fixing agent can be determined. This standard provides a unified testing basis for quality control and product development of fixing agents.
纺织染整助剂生产企业和质检机构使用本标准来评估棉用固色剂的性能。通过测定固色前后织物的色牢度提升和色变程度，可以判断固色剂的实际效果。该标准为固色剂的质量控制和产品开发提供了统一的测试依据。

This standard specifies a test method for determining the color fixing effect of fixing agents for cotton, applicable to fixing agents used for cellulosic textiles. It involves dyeing cotton fabric with reactive dyes of poor color fastness, followed by fixation treatment, and comparing color fastness (e.g., washing, rubbing, perspiration) and color change before and after fixation to evaluate the fixing agent's performance. The standard details procedures for dyeing, fixation (exhaust and pad methods), result processing, and includes a normative annex for solid content determination.
本标准规定了棉用固色剂固色效果的测定方法，适用于纤维素类纺织品固色处理用固色剂的评价。通过选用色牢度较差的活性染料对棉织物染色，然后进行固色处理，比较固色前后织物的色牢度（如耐洗、耐摩擦、耐汗渍等）和色变程度来判定固色效果。标准详细描述了染色、固色（浸渍法和浸轧法）、结果处理等步骤，并规定了含固量的测定方法。

本标准规定了棉用固色剂固色效果的试验方法。
选择色牢度较差的染料对棉织物染色、皂洗并进行固色处理，检测固色前后的色牢度和固色色变，来表征棉用固色剂的固色效果。
固色后织物的色牢度提升越多，固色色变越小，则固色剂的固色效果越好。
将全棉染色织物投入配好的棉用固色剂工作液中，使工作液温度以3.0℃/min的速率升至50℃，保温20 min，固色结束。
将固色前后织物在GB/T 6529规定的条件下调湿。按照GB/T 6688规定的方法，以固色前的染色布为标样，用测色仪测定固色后色布的ΔL*、Δa*、Δb*、ΔE*。ΔE*越大，固色剂的色变越大。
This standard specifies the test method for the color fixing effect of fixing agents for cotton.
Select dyes with poor color fastness to dye cotton fabric, wash and perform fixation treatment, and test the color fastness and color change before and after fixation to characterize the color fixing effect of the cotton fixing agent.
The more the color fastness of the fabric after fixation improves and the smaller the color change, the better the fixing effect of the fixing agent.
Immerse the dyed cotton fabric into the prepared working solution of the cotton fixing agent, raise the temperature of the working solution to 50°C at a rate of 3.0°C/min, keep it warm for 20 min, and finish the fixation.
Condition the fabrics before and after fixation under the conditions specified in GB/T 6529. According to the method specified in GB/T 6688, use the dyed fabric before fixation as the reference and measure ΔL*, Δa*, Δb*, ΔE* of the fabric after fixation with a colorimeter. The larger ΔE*, the greater the color change of the fixing agent.
