Liangjiang brand- Chemical Fiber Titanium Dioxide For Chinlon Chemical Fiber, The 1166 Chemical Fiber TiO2 is produced based on the production method of 1966 with improvement in the industrial process and is primarily used as matting agent in chinlon chemical fiber (Nylon 6 and Nylon 66) manufacturing .

Typical technical data sheet( standard: Q/VAIP-2010)

Transportation: In transportation, chemical fiber titanium dioxide should be kept dry and free from exposure to rain. Combined shipment with goods that may deteriorate its quality or damage the packing is strictly prohibited. Ensure product safety and packing cleanliness during transportation.

Storage: In storage, chemical fiber titanium dioxide should be kept dry, ventilated and free from exposure to light, and is preferably kept indoors or in a place with a canopy. The storage site should be kept clean and free from exposure to sunlight, moisture and rain. The validity period is 3 years as of the date of production. Upon the expiration of the validity period, the product is subject to re-inspection of all items and approval before it is used.

Description:

1. The refractive index contrast between white pigment and synthetic fiber:

Tio2, high opacity, One of the most basic characteristics of good white pigments. Opacity is caused by refractive index difference between pigments and the surrounding mediums.

When refractive index of pigments and the refractive index of binder the same, shows transparent; When refractive index of pigments is greater than the refractive index of blinder, it is opaque, the larger difference, the stronger opacity.

The sheet shows the refractive index of pigments is higher than of general white pigments,two times as the refractive index of common synthetic fiber, besides, small particle size, good dispersibility, stable chemical properties, so putting 0.2% to 0.5% tio2 into the synthetic fiber can reach the flatting effects.

2. The cost of tio2 using in fiber is about 1%, the using of tio2 fiber grade is not like of the coatings. Using in coatings, if not good whiteness, matching color to remedy. If bad fitness, grinding repeatedly. If the bad quality of tio2 as Flatness, it will immediately cause the filter at a slower pace, and blockage of the jet hole, broken wires, hair silk, bad appearances of the fibers and so on. Liangjiang brand- titanium dixoide fiber grade, fine particles, almost no coarse particle, narrow particle size distribution and uniform, good dispersibility, and less impurity content, When using, not wear pipe, nozzle and wire cutting knife;Chemical stability, heat resistance, good resistance to light easy dispersion in bulk, fiber, and scattered and good stability, small filter resistance;After the extinction , not affects the strength of the fiber and spinning processing, once the sample passes the test, we can ensure the quality stability.

Titanium dioxide, another important application fields, Textile and chemical fibre industry as flatting agent.Generally, using anatase in fibers because of the more softness than rutile. Titanium dioxide fiber grade doesn’t need surface treatment. But using in some special products, to bring down the tio2 photochemical action, avoid fiber in the role of tio2 photocatalysis drop solution,

3. Liangjiang brand-Titanium dioxide fiber grade , the request for particle size and distribution.

※ Due to the visible light wavelength of 400-700 nm, the titanium dioxide particle size should select the range from 0.15 um to 0.35 um, so the chemical fiber extinction effect is best.

※When the particle size is too big (more than 0.5 um), it will reduce the performance of titanium dioxide on the short wave scattering, which have effects in fiber.

※ If big particle size at the same time, it can make the filtering performance poor, easy to block spinneret, which affects harmfully on the spining.

※ Does (such as less than 0.1 um) when particle size is too small, the diffraction of light, the light will be through from around the particles, not reflection, will become transparent crystal particles, titanium dioxide extinction ability can be lost.

※ Does often requires more than 90% of the titanium pigment particle size should be less than 1-2 um, the most important thing is try to contain no more than 5 um coarse particles.
