1. for polyester chips

化纤级钛白粉为白色粉末、不溶于水，无生理毒性，化学性质稳定，具有较轻的消色 力、遮盖力等优良性能。由于具有接近于聚酯中的折射率，在添加到聚酯中时，利用两者的折射率之差达到消光的目的，降低了化学纤维的光反射率，消除了不适宜的光泽。是最理想的聚酯消光物质，广泛用于化纤、纺织等领域。

Titanium dioxide of chemical fiber grade is white powder, insoluble in water, non-physiological toxicity, stable chemical properties, with light coloration, covering power and other excellent properties. Because the refractive index is close to the refractive index in polyester, when added to polyester, the difference of refractive index between the two can be used to extinct light, reduce the light reflectivity of chemical fiber and eliminate the unsuitable gloss. It is the most ideal polyester matting material. It is widely used in chemical fiber, textile and other fields.

2. 用于粘胶纤维

2. for viscose fiber

在化纤行业与纺织行业应用起到增白与消光。同时也可以增加纤维的韧性，与柔软度。粘胶专用化纤钛白粉需提高二氧化钛的电阻率，防止在添加使用之中产生钛白粉的二次凝聚。防止钛白粉的二次凝聚可以经过离心机使钛白粉的粒度达到较好的平均值同时在生产或使 用过程中提高研磨时间，让钛白粉的粗大粒子减少。

In the chemical fiber industry and the textile industry, the application of whitening and extinction. At the same time, it can also increase the toughness and softness of the fibers. It is necessary to increase the resistivity of titanium dioxide and prevent the secondary agglomeration of titanium dioxide in the process of adding and using. Preventing the secondary agglomeration of titanium dioxide can make the particle size of titanium dioxide reach a better average value by centrifuge and improve the grinding time during production or use, so that the coarse particles of titanium dioxide can be reduced.

3. 用于色母粒

3. for Color Masterbatch

化纤级二氧化钛，用于色母粒起到消光剂作用，通过与PP、PVC等塑料色母粉混合后，通过双螺旋挤出机，融合、混合、挤压成型。消光剂白色母粒是直接用于纤维生产的原料，化纤级二氧化钛在其中的添加量处于30-60%之间。要求粒度分布均匀，色相符合要求，低二次热凝聚等。

Chemical fiber grade titanium dioxide is used as a matting agent for color masterbatches. It is mixed with PP, PVC and other plastic color masterbatches, then fused, mixed and extruded by a double-screw extruder. The matting agent White Masterbatch is the raw material directly used in fiber production, and the amount of chemical fiber grade titanium dioxide is between 30-60%. It is required that the particle size distribution is uniform, the hue meets the requirements, and the two thermal condensation is low.

4. 用于纺纱（涤纶、氨纶、腈纶、锦纶等）

4. for spinning (polyester, spandex, acrylic, nylon, etc.)

化纤级二氧化钛用于纺纱中，主要起到消光、增韧作用，其中部分企业采用免研磨工艺，其他则采用研磨工艺。其区别在于：是否在混合纺纱之前，将二氧化钛与其纺纱原料一起砂磨。免研磨工艺要求化纤级二氧化钛分散性能良好，低二次热凝聚，粒度分布均匀。

Chemical fiber grade titanium dioxide used in spinning, mainly play a matting, toughening role, some enterprises use non-abrasive process, the other use of abrasive process. The difference lies in whether the titanium dioxide and its spinning materials are sanded together before mixing spinning. Non-abrasive process requires chemical fiber grade titanium dioxide with good dispersion, low secondary thermal condensation and uniform particle size distribution.
