The practical difference is where the product is used实际区别首先体现在产品用于哪里
On the DNS website, fluorescent dye products are separated into disperse fluorescent dyes for polyester and solvent dyes for plastics. Fluorescent pigments are presented for inks, coatings and creative applications.在德诺森网站中，荧光染料产品分为用于涤纶的分散荧光染料和用于塑料的油溶染料；荧光颜料则用于油墨、涂料与创意应用。
This application map is the most direct first filter. It avoids applying polyester dyeing conditions to plastics, inks or coating systems.这一应用对应关系是最直接的第一层筛选，也能避免把涤纶染色条件套用到塑料、油墨或涂料体系。
Compare the three DNS product families对比德诺森三类产品
| Product family产品类别 | Published substrate/application网站公开的基材/应用 | Published route网站公开路线 | Relevant page相关页面 |
|---|---|---|---|
| Disperse fluorescent dyes分散荧光染料 | Polyester涤纶 | HT/HP, thermosol, printing高温高压、热熔、印花 | Products产品页 |
| Solvent dyes油溶染料 | Plastics and masterbatch塑料与色母粒 | Plastic application selection塑料应用选型 | Solvent Yellow 160:1 |
| Fluorescent pigments荧光颜料 | Inks, coatings, creative applications油墨、涂料、创意应用 | Application-system selection应用体系选型 | Fluorescent pigments荧光颜料 |
The published HT/HP starting point—130 °C, pH 4.5–5.5, 45 minutes and 1:25 liquor ratio—and the 180–220 °C thermosol range belong to the polyester disperse-dyeing context. Substrate, equipment and target change the final conditions.网站公开的高温高压实验起点——130 °C、pH 4.5–5.5、45 分钟和 1:25 浴比——以及 180–220 °C 热熔范围，均属于涤纶分散染色语境。基材、设备和目标效果会改变最终条件。
Three first-step selection examples三个第一步选型示例
Polyester textile project涤纶纺织项目
Begin with the disperse fluorescent dye catalog, then choose an HT/HP, thermosol or printing trial route.先查看分散荧光染料目录，再选择高温高压、热熔或印花的试验路线。
