Description
Technical Field
The invention belongs to the technical field of spinning, and relates to superfine fiber/short fiber rotor composite yarn.
Background
In recent years, high value added textiles have become increasingly popular in the market. The superfine fiber yarn has the advantages of good heat insulation, warm keeping, adsorption, sound absorption, filtration and other functional effects due to fluffy yarn structure and more pores, so that the superfine fiber yarn has high added value and wide market prospect. At present, two main technical schemes are available for spinning superfine fibers, firstly, the superfine fibers are formed into chemical fiber bundles and then are made into superfine fiber yarns through a spinning process, but the superfine fiber chemical fiber bundles are basically formed by superfine fiber nets, so the orientation degree of the superfine fibers in the chemical fiber bundles is poor, and the mechanical strength of the prepared superfine fiber yarns is also poor; and secondly, the superfine fibers and the chemical fiber filaments are compounded in a mechanical entanglement mode or coated on the surfaces of the chemical fiber filaments and the yarns, but the superfine fibers in the superfine fiber composite yarns prepared by the method are unevenly distributed and are often attached to the surfaces of the yarns, so that the functional effect of the superfine fiber yarns is influenced, and meanwhile, the superfine fiber composite yarns spun by the method are poor in stability and durability and influence the comprehensive performance of subsequent textiles due to the fact that the superfine fibers are very easy to fall off in the subsequent processing process due to the weak mechanical performance of the superfine fibers.
Disclosure of Invention
The present invention has been made to solve the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide an ultrafine fiber/short fiber rotor composite yarn which is uniformly combined, has a stable structure, and has superior mechanical properties and processability.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a superfine fiber/short fiber rotor composite yarn is characterized in that the whole superfine fiber/short fiber rotor composite yarn is of a rotor yarn structure and is composed of superfine fibers and short fibers, and the superfine fibers and the short fibers are compounded through mechanical entanglement cohesion generated by twisting and thermal bonding action generated by the residual temperature of the superfine fibers;
the diameter of the superfine fiber is 1-5 mu m; the linear density of the short fibers is 1.0-5.0 dtex, and the length of the short fibers is 10-50 mm.
As a preferred technical scheme:
the superfine fiber/short fiber rotor composite yarn has the fineness of 10-100 tex and the twist of 50-150 twists/10 cm.
The superfine fiber/short fiber rotor composite yarn has the mass content of superfine fibers of 0.1-20.0 wt%.
The superfine fiber/short fiber rotor composite yarn is prepared by a melt-blown spinning method.
The superfine fiber/short fiber rotor composite yarn is prepared from polypropylene, polyester, polyamide, polylactic acid, polychlorotrifluoroethylene or polyesteramide as raw materials of melt-blown spinning.
According to the superfine fiber/short fiber rotor composite yarn, the short fibers are cotton, flax, viscose, terylene or acrylic fibers.
An microfiber/staple rotor composite yarn as described above, which is prepared by mixing and coagulating the microfiber and staple in a rotor of a rotor spinning machine and then twisting into a yarn.
The superfine fiber/short fiber rotor composite yarn has the advantages that superfine fibers and short fibers are uniformly compounded, the evenness of the composite yarn is good, the variation coefficient of evenness of the composite yarn is less than or equal to 12.0% (the test method is shown in the third section of the tenth chapter of textile material experimental technology), the mechanical property and the processability of the composite yarn are strong, the yarn structure is stable, the breaking strength of the composite yarn is 13.0-30.0 cN/tex, the variation coefficient of breaking strength is less than or equal to 8% (the test method is shown in the second section of the twelfth chapter of the textile material experimental technology), meanwhile, the durability of the composite yarn is good, and the number of double-sided bending cycles (the test method is shown in the fourth section of the twelfth chapter of the textile material science) is more than 4000.
The principle of the invention is as follows:
the superfine fiber/short fiber rotor composite yarn provided by the invention is realized by combining a melt-blown spinning technology and a rotor spinning technology. The spinning component of the melt-blown spinning box is embedded into the rotor spinning device, so that superfine fibers prepared by melt-blown spinning can be directly mixed with short fibers conveyed by the fiber conveying channel in the coagulation groove of the rotor and twisted into yarns under the high-speed rotation action of the rotor. Because the superfine fiber and the short fiber are twisted into yarn after being mixed continuously in the coagulating tank, the superfine fiber is distributed in the rotor yarn body randomly and uniformly, and the formed rotor composite yarn is not easy to untwist, the superfine fiber is not easy to fall off, the structural stability of the rotor composite yarn is good, and the subsequent processability is strong. Meanwhile, the mechanical entanglement and cohesion effect generated by twisting among the short fibers and between the short fibers and the superfine fibers in the rotor composite yarn and the thermal bonding effect between the superfine fibers and the short fibers are high in mechanical property of the rotor composite yarn. In addition, the rotor composite yarn only contains the short fibers and the superfine fibers, so that the rotor composite yarn has more pores, large specific surface area of a yarn body and fluffy structure, and the rotor composite yarn has better functional effect in subsequent use.
Has the advantages that:
(1) according to the superfine fiber/short fiber rotor composite yarn, superfine fibers spun by a melt-blowing method are uniformly compounded in the rotor yarn, the superfine fibers are not easy to fall off, the structural stability and the durability of the composite yarn are good, the mechanical performance of the composite yarn is strong, and the subsequent processability is high.
