Scope: polyester and disperse fluorescent dyes适用范围：涤纶与分散荧光染料

DNS presents disperse fluorescent dyes for polyester through HT/HP, thermosol and printing routes. This page focuses on the two temperature-based routes already published in the website Q&A and application content.德诺森网站将分散荧光染料用于涤纶的高温高压、热熔与印花路线。本页重点整理网站问答和应用内容中已经公开的两条温度工艺路线。

Important boundary重要边界

The figures below do not define a universal recipe. They are experimental starting points for trials on the actual substrate and equipment.以下数字并不构成通用配方，而是针对实际基材和设备开展试验的实验起点。

HT/HP trial starting point高温高压试验起点

Set the bath设定染浴

Published starting point: pH 4.5–5.5 and liquor ratio 1:25.网站公开的实验起点：pH 4.5–5.5，浴比 1:25。

Run the high-temperature stage进行高温阶段

Published starting point: 130 °C for 45 minutes.网站公开的实验起点：130 °C，45 分钟。

Evaluate and adjust评估并调整

Compare the trial result with the target, then adjust for the substrate and equipment before defining production conditions.将试验结果与目标效果对比，再根据基材与设备调整后确定生产条件。

Thermosol trial starting point热熔试验起点

The thermosol route published on the DNS website is organized as pad, dry, and thermofix. The listed drying range is 70–90 °C, followed by a thermofix starting range of 180–220 °C for 90 seconds.德诺森网站公开的热熔路线依次为浸轧、预烘和热熔。网站列出的预烘范围为 70–90 °C，随后以 180–220 °C、90 秒作为热熔实验起点。

Pad浸轧

Begin the published thermosol sequence with the padding stage.按照网站公开路线，从浸轧阶段开始。

Dry预烘

Published laboratory starting range: 70–90 °C.网站公开的实验起始范围：70–90 °C。

Thermofix热熔

Published laboratory starting range: 180–220 °C for 90 seconds.网站公开的实验起始范围：180–220 °C，90 秒。

Why the final conditions may differ为什么最终条件可能不同

The same numbers cannot be treated as a fixed setting for every trial. Substrate construction, equipment and the target result can change the final conditions.同一组数字不能作为所有试验的固定设定。基材结构、设备和目标效果都会改变最终条件。

  • Confirm that the substrate and route match the published polyester disperse-dye scope.确认基材和路线符合网站公开的涤纶分散染色范围。
  • Use the published figures to set the first laboratory trial.使用公开数字设定第一次实验室试验。
  • Adjust the process after evaluating the actual trial result against the target.根据实际试验结果与目标效果的对比调整工艺。

Frequently asked questions常见问题

What HT/HP starting point does DNS publish?德诺森公开的高温高压实验起点是什么？

130 °C, pH 4.5–5.5, 45 minutes and a 1:25 liquor ratio. These values require trial adjustment.130 °C、pH 4.5–5.5、45 分钟和 1:25 浴比。这些数值需要通过试验调整。

What thermosol temperature range does DNS publish?德诺森公开的热熔温度范围是什么？

180–220 °C as a laboratory starting range, not a universal production setting.180–220 °C，作为实验起始范围，而非通用生产设定。

Can these figures be copied directly into production?这些数字可以直接用于生产吗？

No. Final conditions must be adjusted through trials for the actual substrate, equipment and target.不可以。最终条件必须根据实际基材、设备和目标效果通过试验进行调整。
