| Hook strong (g/d) | 0.62 | 0.42 | 0.28 | 0.31 | 0.32 | 0.38 | 0.35 | 0.29 | 0.42 |
| Dry strong irregularity (%) | 20.0 | 15.7 | 13.2 | 18.4 | 10.5 | 10.3 | 13.6 | 18.3 | 19.6 |
| 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%, brings difficulty will to rear road spinning process.
As shown in table 2, table 2 is barium sulfate domain size distribution table.
Table 2
| Particle diameter (um) | Distribution (%) | Accumulation (%) |
| <0.10 | 7.984 | 7.984 |
| 0.10—0.25 | 4.745 | 12.729 |
| 0.25—0.50 | 11.128 | 23.88 |

| 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 greater than 3um and is less than 1um, its abundance does not reach requirement, and therefore, barium sulfate particle diameter optimum range is between 1um to 3um.
Because barium sulfate itself is a kind of crystal structure, cohesiveness will be produced when intermolecular force acquires a certain degree, even if pulverize again thin also easily crystallization, easily cause the blocking of spinneret orifice, impact spray silk is produced and is carried out smoothly, when strict control barium sulfate particle diameter, spinnerets need adopt larger aperture and often exchange.
The X-ray tracker wire that above-mentioned technique is obtained is carried out spinning batch production.
Spinning: spinning material barium sulfate viscose spinning, fineness is 2.6dtex, and fibre length is 51mm, and yarn number 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 Speed frames → FA503 type fine spining machine → automatic winder → twist thread.
Viscose fiber exists powerful low, poor flexibility, the feature of wear-resisting difference, and baric fiber is poorer in the index of these several respects, dry strong reduction by 52%, wets and falls 48% by force, 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: in the how loose tip-tap of grasp, 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, make every effort to tip-tap in case interrupt fiber, because fiber strength is low, still some fiber is interrupted, cause short fiber 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, prevent the technological principle that barium agent comes off, reduces the rotating speed of cylinder licker-in, regulates fibroreticulate tension force and drafting multiple, prevent 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 be respectively 0.28,0.25,0.25,0.25,0.28mm.
Drafting: adopt the low speed of a motor vehicle of light tension force, prevents barium agent from coming off, improves evenness quality.Adopt two roads and close, 6 and close before this, two roads are 8 and close.Slubbing drafting is dry is quantitatively 18.22g/5m, and number of doubling 6, quantitative 17.72g/5m done by total draft multiple 6.16, two road drafting, 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, because fiber strength is low, need adjust in twist parameter, if the twist is little, broken end is many, cannot normally produce.Dry quantitative 6.018g/100m, drafting multiple 11.79, the twist 48.43, twist factor 399.Ratch 52.5 × 65.5mm.
Winder: the technological principle adopting small tension receiving coil, low velocity, automatic joint, removes yarn defect impurity further and controls rolling tension force.Bobbin winder speed 800m/min.
Twist thread: in order to X-ray development is clear and increase all even raising intensity of yarn evenness, yarn is 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 numbers 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 larger 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 content 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 shown in Figure 1, X-ray diffraction is tested: the angle of rotating according to sample, records 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, be exactly X-ray tracker wire with standard barium sulfate diffraction contrast figure, 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, and after perspective, yarn can have obvious white vestige display on black egative film, and definition is good.
Medical test, detects the toxicity of X-ray tracker wire with animal by GB7919-87.Solution preparation: get a certain amount of this product, add a certain amount of physiological saline and sterilize one hour under high temperature 121 degree, leachate is for zoopery.
Test result is, abnormal toxicity test: toxic reaction without exception; Hemolytic test: conform with the regulations; Skin Irritation Test: this product 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 allergic reaction.
X-ray tracker wire is as hospital gauze rule, and whether be have gauze to stay in the body in the inspection of surgery used after operation X ray tester, as X-ray development illustrates gauze in vivo, otherwise gauze takes out.This is one of safeguard of operation quality.X-ray tracker wire also can be used as the curable product of other specifications as the use of 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 materials.
Utilize preparation method of the present invention, the output of X-ray tracker wire reaches batch production, reduces the cost of yarn import, has saved foreign exchange, has good Social benefit and economic benefit.X-ray tracker wire can improve development technology further, to improve fibre and yarn intensity, improves yarn row yielding.Also can expand the Application Areas of X-ray tracker wire further, making scientific achievement is better community service.
