Description:

Titanium dioxide fiber grade have the basic features of white pigment, the special request for particle size, particle distribution, whitness, impurity contents and so on.

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.

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

White pigment	refractive index	Synthetic fiber	refractive index
Tio2( anatase)	2.55	Polyester	1.725
Tio2(rutile)	2.76	polyacrylonitrile	1.515
Barium sulfate	1.64	Acetate	1.37
Zinc oxide	2.02	viscose	1.546
antimony oxide	2.19	Ketone ammonia	1.572
Zinc sulfide	2.37	Nylon-6	1.558
lithopone	1.84	Nylon-66	1.558

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.

we aspires to be the supplier of the world's leading chemical raw materials, show our value of the products made in China!
