Problems solved by technology

[0004] There are X-ray tracking lines produced in foreign countries, but the price is high. In China, there are researches on X-ray imaging fibers produced with polypropylene as the matrix, but the material, feel and production process are different from barium-containing viscose fibers, which are produced by barium-containing viscose fibers. X-ray tracking line is still blank in China
[0005] The development of X-ray tracking line is a difficult scientific research task, involving knowledge of many disciplines such as medicine, fiber and spinning, chemical auxiliaries, etc. The process is long and difficult to process

Embodiment Construction

[0046] The X-ray tracing line includes barium sulfate grinding liquid and viscose slurry.

[0047] 1. Preparation of barium acid grinding solution

[0048] Grind the barium sulfate particles so that more than 95% of the particles are below 3um, the purity of the barium sulfate is 98%, and the weight percentage is 10%, and then the weight percentage is respectively pigment: ketone phthalocyanine 4%, dispersant: fatty alcohol Polyoxyethylene ether silane 2.5%, penetrating agent: fatty alcohol polyoxyethylene ether 0.5%, leveling agent: fatty alcohol ethylene oxide condensate 0.4%, defoaming agent: alkyl silicone oil 0.5%, water 82.1%, made into a certain concentration of emulsion.

[0049] 2. Preparation of viscose slurry

[0050] Viscose fiber belongs to regenerated cellulose fiber, which is made of natural cellulose such as wood or cotton linters. The biggest feature of viscose fiber is that it is similar to some properties of natural fiber cotton. Viscose fiber has good mo...

Abstract

The invention relates to the technical field of dressing materials in surgical products, particularly a viscose fiber X-ray tracking line containing high-dose barium sulfate. The viscose fiber X-ray tracking line containing high-dose barium sulfate comprises a barium sulfate grinding fluid and a viscose slurry. The tracking line is characterized in that the proportion of the barium sulfate grinding fluid to the viscose slurry is 1:1. The barium sulfate grinding fluid comprises barium sulfate, a pigment, a penetrant, a dispersing agent, a leveling agent and water, wherein the pigment is ketone phthalocyanine blue, the penetrant is fatty alcohol polyethenoxy ether, the dispersing agent is fatty alcohol polyethenoxy ether silane, the leveling agent is fatty alcohol epoxyethane condensate, and the defoaming agent is alkyl silicon oil. Compared with the prior art, the X-ray tracking line yield of the preparation method achieves mass production, and the preparation method lowers the yarn import cost, saves the foreign exchange and has favorable social benefit and economic benefit.

Description

technical field [0001] The invention relates to the technical field of dressing materials in surgical supplies, in particular to an X-ray tracing line of viscose fiber containing a large dose of barium sulfate. Background technique [0002] The X-ray tracking line is used as a medical gauze embedding line. After surgery, the X-ray detector is used to check whether there is gauze left in the body. If the X-ray film is developed, the gauze is in the body, otherwise the gauze has been taken out. This is one of the safeguards for the quality of surgery. X-ray tracking line can also be used as other specifications of medical products such as lumbar and abdominal pads. According to the anti-X-ray performance of the X-ray tracking line, anti-ray products can be further developed to become a new type of protective material. [0003] X-ray tracking thread is a kind of medical special yarn developed by special spinning and spinning process with barium sulfate additive. After perspe...
