Description
Technical Field
the invention relates to a preparation method of a special oiling agent for vortex spun-bonded adhesive fibers, belonging to the technical field of textile auxiliaries.
Background
Vortex spinning is different from ring spinning and rotor spinning, and the yarn forming principle is as follows: the fed sliver is drafted by a four-roller (or five-roller) drafting device to obtain a parallel fiber bundle with a set yarn count, and the fiber bundle is sucked into a nozzle by means of negative pressure. The front end of the fiber bundle is pulled by the tail end of the yarn being formed to enter the yarn withdrawal tube; under the action of the axial component force of the high-speed vortex, a part of fibers in the rear end of the fiber bundle are inverted at the inlet of the yarn-withdrawing pipe. The reverse fiber exposed in the rotary airflow ejected from the nozzle is twisted on the yarn tail along with the rotation of the airflow to form true twisted yarn output. The wrapping angle and the revolving angle of the fiber bundle on the spindle can be adjusted according to the process.
The high-speed rotary machine parts such as spindles, steel wire rings and the like in the vortex spinning non-ring spinning are twisted into yarns by rotating vortex, and compared with mechanical twisting, the efficiency is obviously improved. The rotary vortex only realizes the twisting action and does not influence the yarn number, high-speed spinning can be realized based on the principle, the highest spinning speed of the vortex spinning of Jiangsu Shixiang textile company can reach 500m/min, and the single-spindle yield is more than 24 times of that of ring spinning. Because the fiber is subjected to the action of air-jet vortex and take-up roller to form true twist, the twisting mode can not be replaced by other spinning machines, and the yarn-forming structure is more compact.
Compared with the traditional ring spinning and novel rotor spinning, the vortex spinning technology has the following characteristics:
(1) the production efficiency is high;
(2) The spinning process is short;
(3) The labor is minimum;
(4) The quality control means of the vortex spinning machine is advanced;
(5) Vortex spun yarns are distinctive;
(6) the production cost is low.
The viscose fiber is cellulose fiber obtained by extracting and remolding fiber molecules from natural wood cellulose by taking wood pulp as a raw material, and belongs to one of regenerated cellulose fibers. The viscose fiber has good hygroscopicity, meets the physiological requirements of human skin, and has the characteristics of smoothness, coolness, air permeability, static resistance, ultraviolet resistance, gorgeous color and good dyeing fastness. It has the nature of cotton, the quality of silk. The fabric is widely applied to the fields of various underwear, textile, clothes, non-woven fabrics and the like.
The surface of the natural fiber is provided with a layer of natural grease, and the natural fiber has good textile performance. After the viscose fiber is formed, the surface of the viscose fiber is free of grease after the impurities are removed through the procedures of washing, desulfurization and the like, the viscose fiber cannot be directly spun, and oiling treatment is carried out on the surface of the fiber through an oiling procedure. The oil used by most enterprises at present is imported oil, and viscose fiber is oiled by the imported oil to endow the fiber with good surface performance, so that the spinning requirements of common ring spinning, compact siro spinning and low-speed vortex spinning can be met.
The oil agent is an important chemical agent for the post-treatment of viscose fibers, and can increase the softness and smoothness of the fibers, improve the hand feeling of the fibers, reduce the electrostatic effect of the fibers, reduce the friction coefficient of the fibers and increase the cohesive force of the fibers, thereby improving the spinning spinnability and the yarn quality. The viscose fiber has the following requirements on oil agent: the oil solution is convenient to use and can be uniformly adsorbed on the surface of viscose fiber, so that the fiber is not wound and does not stick to a roller in the spinning process and has excellent cohesive force; endows the fiber with a certain antistatic effect, and can reduce the generation of electrostatic phenomenon in the spinning process as much as possible; the stability of the oil solution emulsion is good, and the oil solution emulsion is not layered after being stored for 24 hours; a certain thermal stability is required. In the drying process, the oil film is not deteriorated due to high temperature, sticky, yellow and volatile, and is beneficial to improving whiteness; the oil solution emulsion has less foam and no corrosion to metal.
The oil content of the fiber is strictly controlled, the fiber cannot meet the requirements of a spinning process when the oil content is too low, and the fiber is stuck to a roller during spinning when the oil content is too high, so that the spinning processing is difficult. The oil content is also related to the climate condition and the air humidity, and is controlled to be higher in winter. The oil content of the fiber is related to the concentration of the oil solution bath, the circulation amount of the oil bath, the temperature of the bath, the water content of the fiber during oiling, the high-pressure rolling process after leaving the oil bath and the drying temperature. The oil content is generally controlled between 0.2mg/100g and 0.7mg/100 g. The row mark requirement is between 0.15mg/100g and 0.30mg/100 g.
Most of oil agents used by viscose fiber manufacturers at present are imported oil agents, and indexes such as friction coefficient, cohesive force, specific resistance and the like of fibers using the oil agents can meet the requirements of traditional ring spinning and compact siro spinning; the novel spinning has no roving process like vortex spinning, the surface property requirement of fiber raw materials is high when the bobbin yarns are directly drawn to post-spinning, and the surface property of the fibers given by the currently used oil agent can still meet the requirement of low-speed vortex spinning.
the vortex spinning yarn principle is different from the traditional ring spinning, when the ring spun yarn is twisted, the inner layer and the outer layer of the single yarn have the same twist; the inner layer of the vortex spinning single yarn is formed by longitudinally and linearly arranging a plurality of fibers in a staggered mode without twist, and the outer layer of fibers has twist and wraps the inner layer of fibers. Therefore, the strength of the vortex spun single yarn is lower than that of the ring spun single yarn, and the vortex spinning has higher requirement on the surface property of the fiber raw material in high-speed spinning: if the friction coefficient is lower, the fibers are well combed without entanglement in the vortex spinning cotton carding process, the neps are less, the coarse and fine details of the finished yarn are less, the shearing number is less, and the efficiency is improved; the low specific resistance ensures that the static electricity of the fiber is less in the carding, drawing and drawing processes, and the surface of the sliver is smooth and is not easy to hang flower; the outer layer fiber does not slip in the twisting process due to a certain cohesive force, the fiber strength is enhanced, the yarn is not broken during forming, the efficiency is improved, and the yarn quality is improved.
The friction coefficient, specific resistance, fluffiness and cohesion of the fiber are key parameters in spinning, for example, the fiber is required to be easy to open, easy to comb, free from static electricity and damage the fiber in the blowing-carding process, so that the fiber is required to have lower friction coefficient and specific resistance, and the fiber is less in sliver neps through combing; the cotton carding, drawing and drawing processes require that fibers have certain fluffiness and cohesion to keep the circular section of the cotton sliver; the yarn forming process from sliver spinning to single yarn spinning requires that the fibers have certain cohesive force, so that the outer layer fibers do not slip and the inner layer fibers are better wrapped. Therefore, the development of special oiling agents for vortex spun-bonded viscose fibers is necessary to endow the fibers with surface properties suitable for vortex spinning, and the preparation method has wide application prospects.

Comparative example: the special oiling agent for vortex spinning viscose fiber produced by Dongguan company.
After oiling the viscose fiber, the special oiling agents prepared in the embodiments and the comparative examples are detected, and the detection is as follows:
determination of the oil content of the fiber: soxhlet extraction is adopted, the oil on the fiber is extracted into a distillation flask by using ether by utilizing the property that the oil can be dissolved in an ether organic solvent, and the obtained liquid is evaporated and dried to obtain the oil which is not easy to volatilize.
Determination of the coefficient of friction of the fibers: firstly, the oiled viscose fiber is manually made into a fiber roller, and the fibers on the fiber roller cannot be entangled with each other and cannot be curled. Then, friction coefficient test is carried out on the oiled viscose staple fibers by adopting a winch method, and the tester is a YG151 type fiber friction coefficient tester, and the initial tension is 0.2 cN. When measuring the dynamic friction coefficient, the rotating speed of the fiber roller is set to be 30 r/min; when the static friction coefficient is measured, the fiber roller is kept still, the handle of the torsion balance is slowly and manually rotated at a constant speed, the rotation of the handle is immediately stopped when sudden slippage occurs between the fiber and the fiber roller, and the reading on the torsion balance when the pointer begins to deflect is read. And randomly selecting 5 fibers from each fiber sample to test the friction coefficient, wherein each fiber is tested twice, and the average value is taken as the test result.
Fiber mass specific resistance test: the method comprises the following steps: randomly extracting 50g of the fiber sample, loosening by hands, balancing for more than 4 hours under a standard atmospheric condition, and weighing 3 parts of test sample, 15g of each part, by using a balance with the precision of 0.01g for use in testing; according to the standard GB/T14342-1993, during testing, the fiber measuring box is taken out of the case, the pressing block is taken out by a special hook of the instrument, a weighed fiber sample is uniformly filled into the box by tweezers, then the pressing block is pushed in, then the fiber measuring box is put into the instrument, and the handle is rotated until the fiber measuring box is not shaken.
the specific test results are shown in table 1.
Table 1 comparative table of property characterization
| Detecting items | example 1 | Example 2 | Example 3 | Comparative example |
| Oil content of fiber/mg/100 fiber | 0.20 | 0.21 | 0.22 | 0.7 |
| Coefficient of friction | 0.118 | 0.123 | 0.115 | 0.291 |
| Fiber mass specific resistance/108Ω•g/cm2 | 7.8 | 7.9 | 7.6 | 9.5 |
