Abstract
The X-ray detectable composite fiber comprises A and B two parts which are processed on composite melt spinning machine, in which the A wraps the external layer of B. A is composed of polymer material with no or less barium sulfate and B is composed of 50.0-99.0% of barium sulfate and 1.0-50.0% of polymer material. The weight ratio of A and B is (20-50)/(50-80). Each single fiber has good textile machining property and excellent X-ray developing ability, which can prevent the patient after operation from various complication resulted by the gauze left in patient's organ.
Description
Technical field:
The present invention relates to field of medical materials, be specifically related to detectable composite fibre of a kind of fabric of island-in-sea type X-light and preparation method thereof.
Background technology:
The major function of the medical tracker wire of X-ray is the developing function that increases hospital gauze.The medical tracker wire of traditional X-ray is to be made by polyvinyl chloride or other elastomeric material, and these materials and pulverous barium sulfate mix the back by melt extruding moulding.After inweaving or scalding gauze, the yarn of barium sulfate-containing or thin slice can clear developments in X-light is detected.After containing the medical tracker wire of X-ray in the gauze, after operation, do a simple X-light and detect and just can avoid in the medical operating, even cause malpractice such as death owing to gauze is omitted the various complication that cause in patient's internal organs.In gauze, add the normal diagnosis that the medical tracker wire of X-ray helps the medical treatment of patient's postoperative, avoid state of an illness diagnosis of complexization; Simultaneously doctor, nurse can be checked the system and free from perioperatively cumbersome " three-controls ", " three pairs " gauze.
The medical tracker wire of various X-rays in the market is processed into after all being mixed with macromolecular material by pulverous barium sulfate.Traditional polyvinyl chloride is that the medical tracker wire of the X-ray of carrier is made up of a monofilament, because diameter is thicker, the feel of product is coarse hardens.Except being the product of carrier by polyvinyl chloride or other rubber, European patent EP 0154423 and European patent EP 0101650 disclose a kind of by the yarn that is processed into after polypropylene and the mixing of pulverous barium sulfate.Because polyacrylic spinning properties is fine, the polypropylene that contains pulverous barium sulfate can be processed to thinner fiber.The yarn that the medical tracker wire of polypropylene X-ray of European patent EP 0101650 disclosed barium sulfate-containing is made up of 40 filaments.
Chinese patent ZL99116463.6 discloses a kind of by the medical tracker wire of X-ray that is processed into after polyvinyl chloride, polyethylene, polypropylene and the mixing of pulverous barium sulfate.This product adopts nanometer results new technology to prepare the X-ray developing material, can knit altogether with cotton yarn or presses the implantation medical absorbent cotton/gauze, and being used for can clear development under X-ray after the operation.
Because the content of barium sulfate generally just can reach desirable X-ray development capability more than 60%, the intensity of the medical tracker wire of X-ray that is rich in barium sulfate is on the low side, and textile processibility can be relatively poor.
Islands-in-sea bicomponent fibre is a kind of novel chemical fibre production technology, can add two or more macromolecular material in same fiber.The cross section of islands-in-sea bicomponent fibre shows that a kind of small cross section (island) of material is enclosed in (sea) among the another kind of material.Chemical fibre industry is utilizing islands-in-sea bicomponent fibre to prepare the very thin superfine fibre of fibre diameter behind the part macromolecule dissolution in ' sea '.
Summary of the invention:
Technical problem to be solved by this invention is to improve the performance of the medical tracker wire of existing X-ray, utilizes the preparation technology of islands-in-sea bicomponent fibre that a kind of detectable fiber of the compound X-ray of fabric of island-in-sea type that had not only had the X-ray development capability but also had good textile performance is provided.
The detectable composite fibre of fabric of island-in-sea type X-light disclosed by the invention is processed on the composite molten spinning machine by A (being extra large part) and B (being the island part), wherein A is wrapped in the skin of B, A is made up of the macromolecular material that does not contain or contain a small amount of barium sulfate, B is made up of barium sulfate and the 1.0-50.0% macromolecular material of 50.0-99.0%, the weight ratio of A and B is (20-50)/(50-80), and the preferred weight ratio of A and B is 30/70.
Macromolecular material of the present invention is meant the macromolecular material that can be used for producing chemical fibre, comprises polypropylene, polyethylene, polyester and polyamide etc.
Another technical problem to be solved by this invention is to provide the preparation method of the detectable composite fibre of above-mentioned fabric of island-in-sea type X-light.
The detectable composite fibre of fabric of island-in-sea type X-light of the present invention can make by following technical proposals:
1, presses formula ratio barium sulfate powder and the macromolecular material of particle diameter less than 1 micron mixed, make master batch, i.e. B part on the machine in melt extruding of twin-screw;
2, by formula ratio macromolecular material or macromolecular material and a small amount of barium sulfate are melt extruded at twin-screw and make master batch on the machine, be i.e. the A part;
3, A and B are formed composite fibre for (20-50)/(50-80) with weight ratio on fabric of island-in-sea type composite molten spinning machine.
The present invention adopts the macromolecular material of producing chemical fibre as ' sea ', makes the fiber of production have good textile performance, has improved the intensity of fiber simultaneously.And the microfiber ' island ' that contains a large amount of barium sulfate is enclosed in fibrous inside, can not influence the textile performance of whole fiber when increasing barium sulfate content.
Fig. 1 has shown the sectional view of the detectable composite fibre of fabric of island-in-sea type X-light of employing the inventive method production of arriving with microscopic examination.The microfiber ' island ' that contains a large amount of barium sulfate is enclosed among ' sea ' be made up of virgin pp.
' sea ' part that the macromolecular material of the production chemical fibre that the present invention adopts forms can contain barium sulfate in a small amount, further improves the development capability of the detectable composite fibre of fabric of island-in-sea type X-light of the present invention when not influencing the fibre machinery performance.
