Description

For the medical fibre of X-ray-preventing
Technical field
The present invention relates to a kind of medical fibre for X-ray-preventing, belong to technical field of textile fabric.
Background technology
Along with the raising day by day of people's awareness of safety, in world wide, the total flow of security protection series products is also in the trend increased year by year.Security protection fiber is one of important kind of security protection material, be widely used in the fields such as oil, chemical industry, metallurgy, shipbuilding, fire-fighting, army and have naked light, distribute spark, motlten metal and have the place of combustible material.Due to scientific and technological progress, expanding economy, particularly government to the attention of dangerous operation facility personnel security protection, make security protection material all or part of employing new and high technology composite already.
Health type is divided to protect by safeguard function, as radiation proof, cold-proof, heat insulation and antibacterial etc.; Safety-type protects, as fire-retardant, antistatic, shellproof, anti-stab, acid-proof and insect protected etc.; For keeping the protection of health, as grease proofing, dust-proof and refuse water etc.The material of protection, except meeting except high-strength, high-anti-friction etc. requires, often variant because protection object, preventing principle are different, generally there are defence physics, chemistry and biological etc.
Ray to the harm of human body just more and more pay attention to by people, the staff under many specific work environments needs to dress special ray protective clothing.
In general, ray protection material, according to the kind of shielded ray, is also divided into two classes, one is X-ray protection material, primary protection X-ray gamma rays etc., another kind is the protective materials of common Non-ionizing radiation, is mainly used to protection electromagnetic radiation and part long wave ray.At present, X-ray protection material mainly makes of the rubber of leaded (Pb), is used for hospital radiological department at present, school experiment room, nuclear industry environment etc.
Lead belongs to heavy metal has very large harm to human body.Lead can not be decomposed in water, and people drinks rear toxicity and amplifies, and other toxin in water are combined and generate the larger organic matter of toxicity.Plumbous be generally extensively present in occurring in nature with natural concentration, but due to the exploitation of mankind's heavy metal, smelting, processing and business manufacturing activities increasing, cause many lead to enter in air, water, soil, cause serious environmental pollution.The heavy metal that human injury exists with various chemical state or chemical form, will retain, accumulates and move, work the mischief after entered environment or the ecosystem.Plumbous: to be the one that heavy metal pollution Poisoning is larger, to be difficult to get rid of once enter human body, the brain cell of the direct harm people of energy, the particularly nervous system of fetus, congenital feeblemindedness can be caused, the headache of people, dizziness, insomnia, forgetful, refreshing smart entanglement, arthralgia, calculus, cancer can be caused.Plumbous pollution problem is more and more paid attention in China.
Summary of the invention
The object of the invention is to provide a kind of medical fibre for X-ray-preventing, and this medical fiber membrane well can prevent the irradiation of X-ray, can be used for the protective clothing in ward, and has natural degradable function, is all free from side effects to human body and environment.
For achieving the above object, the technical solution used in the present invention is: a kind of medical fibre for X-ray-preventing, and the described medical fibre for X-ray-preventing is obtained by following process, process this comprise the following steps:
Step one, the mass ratio Homogeneous phase mixing under 160 DEG C of conditions viscose glue stoste and rare earth carbonate particulate being pressed 100:2 obtain mixed liquor, this viscose glue stoste is the sodium hydroxide solution including sodium cellulose xanthate, and in sodium hydroxide solution, sodium cellulose xanthate is by being extracted pure alpha-cellulose, obtaining with caustic soda, carbon disulfide process by cellulosic material;
Step 2, defoamer added mixed liquor through step one, in order to remove the foam in mixed liquor;
Step 3, the mixed liquor obtained is cooked further filtration;
Step 4, the mixed liquor of step 3 is extruded formed mixed liquor thread by spinneret orifice after, then through 90 ~ 95 DEG C of coagulating baths, this mixed liquor thread is frozen into spun filament, this coagulating bath comprises following component:
H 2SO 490g/L,
Na 2SO 4170g/L,
ZnSO 485g/L;
Step 5, the spun filament of step 4 carried out drawing-off and form composite fibre long filament;
In described step 2, defoamer is silicone defoaming agent, and addition adds 0.05 ~ 0.10% after pressing 1:6 dilution.
As preferably, between described step one and step 2, be provided with filtration treatment, the particle larger for filtering and impurity.
As preferably, the time of stirring during Homogeneous phase mixing in described step one is 60min.
As preferably, the extensibility of drawing-off in described step 5 is 15 ~ 20%.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
The present invention is used for the medical fibre of X-ray-preventing, and it makes cotton piece through nonwovens process, cotton piece is placed on X ray test instrument and tests its lead equivalent, its test result: lead equivalent is 0.63mmPb.(the protection highest level III of X-ray protection clothes requires lead equivalent >=0.50mmPb), as can be seen from above-mentioned test result, the composite made by the method has the function of good X-ray-preventing; Secondly, because two main raw material viscose glue stostes of the present invention and rare earth carbonate are all natural natural components, there is natural degradable function, human body and environment are all free from side effects.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
Embodiment 1-3: a kind of medical fibre for X-ray-preventing, the described medical fibre for X-ray-preventing is obtained by following process, process this comprise the following steps:
