| Dry extension at break (%) | 18.0 | 21.2 | 22.6 | 22.1 | 17.5 | 23.4 | 24.2 | 20.8 | 19.2 |
As seen from Table 1, the low development that can affect X-ray of barium content, barium content is between 36～46%, and fibre strength reduces by 50%, it will bring difficulty to rear road spinning process.
As shown in table 2, table 2 is barium sulfate particle size distribution table.
Table 2
| Particle diameter (um) | Distribution (%) | Accumulation (%) |
| <0.10 | 7.984 | 7.984 |
| 0.10—0.25 | 4.745 | 12.729 |

| 2.00—3.00 | 38.504 | 95.649 |
| 3.00—5.00 | 4.35 | 100 |
As seen from Table 2, when barium sulfate particle diameter is more than 3um and less than 1um, its abundance does not reach requirement, and therefore, barium sulfate particle diameter optimum range is between 1um to 3um.
Owing to barium sulfate itself is a kind of crystal structure, cohesiveness will be produced when intermolecular force reaches to a certain degree, even if pulverizing again thin also easily crystallization, easily cause the blocking of spinneret orifice, affect spray webbing production to be smoothed out, when strict control barium sulfate particle diameter, spinneret need to adopt bigger aperture and often exchange.
The X-ray tracker wire that above-mentioned technique prepares is carried out spinning batch production.
Spinning: spinning material barium sulfate viscose rayon spins, and fineness is 2.6dtex, and fibre length is 51mm, and yarn count is 68*4tex.
Spinning technological process: A002D type griping cotton machine → A035 type mixed cotton slitter → A036C type card wire opener → A092A type tandem feeder → A076C type lapper → A186D carding machine → FA302 type drawing frame (2 road) → A454C type fly frame → FA503 type spinning frame → automatic winder → twist thread.
Viscose fiber exists powerful low, poor flexibility, the feature of wear-resisting difference, and baric fiber is worse in the index of these several respects, dry strong reduction by 52%, wets and drops by force 48%, and hook is strong reduces by 53%, fineness increases by 140%, and after making spinning, unit cross-sectional area radical reduces, and also have impact on the brute force of yarn.
Therefore, fiber strength is low brings great difficulty to spinning.
Blow room system: grasping the tip-tap of many pines, under the principle that many combs fall less, carry out comb needle type opener and porcupine opener two road shredding, reduce hired roughneck's rotating speed, making every effort to tip-tap in case interrupting fiber, owing to fiber strength is low, still some fiber is interrupted, causing short fibre can not enter postchannel process, the flyings fibre that falls greatly is many.Dry quantitative 326.8g/m, A036 kirschner beater rotating speed about 400r/min, lapper hired roughneck rotating speed about 780r/min.
Carding process: carry out tip-tap, comb more, hinder fiber less, it is prevented that the technological principle that barium agent comes off, reduces the rotating speed of cylinder licker-in, regulates fibroreticulate tension force and drafting multiple, it is prevented that suspension, fall the problems such as barium.Dry quantitative 18.72g/5m, cylinder rotating speed 280r/min, licker-in rotating speed 680r/min, doffing speed 16r/min, cylinder and Flat Gauge respectively 0.28,0.25,0.25,0.25,0.28mm.
Drafting: adopt the low speed of light tension force, it is prevented that barium agent comes off, and improves evenness quality.Adopting two roads and close, 6 and close before this, two roads are 8 and close.Slubbing drafting does quantification of 18.22g/5m, number of doubling 6, total draft multiple 6.16, and two road draftings do quantitative 17.72g/5m, number of doubling 8, total draft multiple 8.22, roller gauge 23 × 30mm.
Rove: consider to reduce filoplume, increase cohesive force, reduce the factors such as broken end, suitably increase and space and the twist.Dry quantitative 6.55g/10m, drafting multiple 5.41, twist factor 65.6.Ratch 61.5 × 70.5mm.
Spun yarn: through test of many times, owing to fiber strength is low, need to adjust in twist parameter, if the twist is little, broken end is many, it is impossible to normally produce.Dry quantitative 6.018g/100m, drafting multiple 11.79, the twist 48.43, twist factor 399.Ratch 52.5 × 65.5mm.
Winder: adopt the technological principle of small tension receiving coil, low velocity, automatic joint, remove yarn defect impurity further and control rolling tension force.Bobbin-winding machine speed 800m/min.
Twist thread: in order to X-ray development is clear and increases all even raising intensity of yarn evenness, yarn being once merged into 4 strands, increase yarn twist, ingot speed is 7000r/min.
As shown in table 3, table 3 is X-ray tracker wire physical index signal table.

| The index of quality | 537 | 656 |
As seen from Table 3, No. 2 test yarns yarn count slightly improve, and are conducive to the development of X tracker wire, and powerful increase by 37%, the index of quality improves 22%, and all the other every physical indexs have bigger improvement.
As shown in table 4, table 4 is X-ray tracker wire barium content test signal table.Barium sulfate-containing yarn burns 2 hours under 800 DEG C of conditions, the powder weighing stayed.By ash detection means, quantitatively measure the content of barium sulfate.
Table 4
| Project | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
| Barium content | 44.2 | 41.2 | 42.2 | 39.3 | 43.1 | 42 | 42 | 41.3 |
As seen from Table 4, yarn barium content, compared with fiber barium content, loses 1-2%.Barium content is between 41%-44%.
As it is shown in figure 1, the test of X-ray diffraction: the angle rotated according to sample, record the diffracted intensity on this this position.Transverse axis represents that angle changes, and the longitudinal axis represents Strength Changes.Intensity represents intensity, volume unit CPS pulses per second.2theta represents 2 θ, angular unit deg angle.
As shown in Figure 2, it is simply that X-ray tracker wire compares figure with standard barium sulfate diffraction, strong in the longitudinal pulse of transverse axis 42.5, identical with barium sulfate agent peaks, represent there is barium sulfate material.
Medical index test, baric yarn film making X ray is according to dosage KV58., MA50, and the time is that 0.06～0.08s can show, after perspective, yarn can have significantly white vestige to show on black egative film, and definition is good.
Medical test, detects the toxicity of X-ray tracker wire by GB7919 87 with animal.Solution preparation: take a certain amount of this product, adds a certain amount of normal saline and sterilizes one hour under high temperature 121 degree, and leachate is for zoopery.
Test result is, abnormal toxicity test: toxic reaction without exception；Hemolytic test: meet regulation；Skin Irritation Test: this product is through rabbit picosecond laser pulse, there are no skin wound repair；Hypersensitive test: this product is through Guinea pig Buehler test, and result is there are no anaphylaxis.
X-ray tracker wire, as hospital gauze rule, is checked whether that gauze stays in the body at surgery used after operation X ray tester, and as X-ray development illustrates gauze in vivo, otherwise gauze takes out.This is one of the safeguard of surgical operation quality.X-ray tracker wire also can as the use of the curable product of other specifications such as waist abdominal pad.Anti-x-ray performance according to X-ray tracker wire also can develop anti-ray product further, becomes a kind of novel protective material.
