酒店布草染料在织物上固着程度不同：尽管染料在织物上先期分布是均匀的，但在固着过程中如条件控制不当(如温度、时间、染化料浓度等)，使织物上某些部位的染料没有得到充分固色，在后处理皂洗时即被去除，从而产生色差。
The fixation degree of hotel linen dyes on the fabric is different: although the dyes are uniformly distributed on the fabric in the early stage, if the conditions are not properly controlled during the fixation process (such as temperature, time, dye and chemical concentration, etc.), the dyes on some parts of the fabric are not sufficiently fixed, and are removed during the post-treatment soaping, resulting in color difference.
染料在织物上先期分布不均匀：染料在固着之前，如果在织物各部位上分布不匀，固色后必然形成色差。造成这种现象的主要原因为：
Uneven distribution of dyes on the fabric in the early stage: if the dyes are distributed unevenly on various parts of the fabric before fixation, color difference will inevitably occur after fixation. The main reasons for this phenomenon are:
(1)织物因素：由于纤维性能不同或前处理退、煮、漂、丝不够匀透，使染前半制品渗透性不匀而引起对染料吸收程度的差异。
(1) Fabric factor: due to different fiber properties or insufficient uniformity of pretreatment, such as desilting, boiling, bleaching and silk, the permeability of semi-finished products before dyeing is uneven, resulting in the difference of dye absorption.
(2)吸液因素;由于机械结构上的原因或操作不当，使织物各部位的带液率不一致，因而造成色差。轧辊压力不匀、加入染化料不匀等都会使织物吸收染料不匀。
(2) Aspiration factor; Due to mechanical structure or improper operation, the liquid carrying rate of each part of the fabric is inconsistent, resulting in color difference. The uneven roller pressure and the uneven addition of dyes and chemicals will make the fabric absorb dyes unevenly.
(3)预烘因素：在浸轧染液后预烘时，由于烘燥的速率和程度不一致，引起染料发生不同程度的泳移，使染料在织物上分布不匀。
(3) Pre-drying factor: during the pre-drying after the dip dyeing solution, due to the inconsistent drying rate and degree, the dye migrates to different degrees, resulting in uneven distribution of the dye on the fabric.
染料色光发生变异：这种差异不是由于织物上染料分布不均匀造成的。而是由于某些原因引起织物上的部分染料的色光发生变化，一般有以下几种原因：
Dye shade variation: this difference is not caused by uneven distribution of dyes on the fabric. It is due to some reasons that cause the color light of some dyes on the fabric to change. Generally, there are the following reasons:
(1)染前因素：半制品的白度不匀或pH值有较大差异，在染色后往往造成色光差异。
(1) Pre-dyeing factors: uneven whiteness or large difference in pH value of semi-finished products often cause color difference after dyeing.
(2)染色因素：例如分散染料热溶温度过高，使某些染料的色光变得萎暗;还原染料的过度还原，也会使色光有差异。
(2) Dyeing factors: for example, the high temperature of thermal solution of disperse dyes makes the color of some dyes dim; Excessive reduction of vat dyes will also cause color difference.
(3)染后因素：在后整理过程中如树脂整理、高温拉幅以及织物上PH值的不同等，都会引起染料色光有不同程度的变化。
(3) Post-dyeing factors: In the process of post-finishing, such as resin finishing, high temperature stretching and the difference of PH value on the fabric, the color of the dye will change to varying degrees.
(4)皂洗：如皂洗不充分，会使发色不充足色光不准。
(4) Soap washing: if the soap washing is not sufficient, the hair color will be insufficient and the color light will be inaccurate.
