Background

With the development of economy and the advancement of science and technology, the change of social consciousness and life style, people put forward more and higher requirements on the functions, diversification and comfort of textiles and clothes. Although the existing common polyester filament yarn and the products thereof have the advantages of high strength, good stiffness and smoothness, easy maintenance, low price and the like, compared with natural fiber, the existing common polyester filament yarn and the products thereof also have the defects of poor hand feeling, comfort and air permeability and the like, so that various manufacturers are forced to continuously develop differentiated ultrahigh-simulation natural fiber products to replace the natural fiber and the products such as fabrics thereof and the like so as to meet the requirements of life quality of people. Therefore, research and development on physical modification, chemical modification and functional textiles of fibers and fiber products are promoted, however, no fiber is absolutely ideal fiber which can be applied to various scene fields regardless of natural fibers or chemical fibers, and any fiber is excellent and has defects. In the production of chemical fiber filament, the style and characteristics of some natural fibers are kneaded to make up for the deficiency. Natural fibers such as wool and silk have less uniform thickness and quality, and the polydispersity enables the textile to have excellent bulkiness or stiffness. Therefore, the mixed filament yarn, which is a bundle yarn having different linear densities, different shrinkage properties, different cross-sectional shapes, different dyeing properties, and the like, is intentionally produced. On the one hand, its application makes it possible to obtain the most suitable and optimal performance of the yarn for a specific use; on the other hand, the defect caused by over-uniformity of the conventional chemical fiber products is overcome. The traditional process for preparing the combined filament yarn is generally a two-step process, namely, filaments with large differences in indexes and performances are respectively spun, and then the filaments of all components are subjected to mixed fiber compounding, network, air deformation, cabling, false twisting, texturing and the like on a stretching texturing machine or a texturing machine and then are processed and stranded, so that the combined filament yarn is prepared, and the two-step process has the advantages that: since the first step is a separate spinning, there is little involvement between the components in spinning. The spun filament has good controllability of thermal shrinkage performance, mechanical property and dyeing performance, the difference of the performances among the components can be made larger, and the style characteristics of the different-shrinkage mixed fiber composite filament after the mixed fiber is compounded are obvious; the disadvantages of the two-step process route: on one hand, the processing route is longer, the process is complex, the equipment investment is larger, the subsequent processing speed is low, the production efficiency is low, the production cost is increased, and the popularization and the application of the product and the economic benefit are limited. On the other hand, when the second step fiber mixing is carried out, the precursor needs to be transferred to a bobbin creel, the precursor is easy to damage in the transfer process, the operation is not facilitated, the labor cost is high, meanwhile, the degree of tightness of the mixed fiber tows is different due to factors such as tension and mixing proportion, the performance of the processed different-shrinkage fiber mixing is unstable, the product quality uniformity is poor, and the improvement of the post-weaving grade is limited. The development of the two-step process is greatly limited by various defects of the two-step process, and meanwhile, the one-step mixed fiber spinning process is promoted to be generated; the one-step mixed fiber spinning technology is a new process developed in recent years, and is a process for completing the spinning process and the mixed fiber composite processing of filament components with different properties in one step. The method mainly separates the tows in the spinning process according to a certain proportion, and makes the tows respectively pass through different thermal history and drafting processes, and then the processes of compounding, oiling and winding are completed in one step, and the processes of spinning, forming, stretching, compounding, networking and winding are completed to obtain the mixed fiber filament with two potential performances. The method mainly comprises one-step one-plate three-differential yarn spinning and one-step plate-combining spinning, wherein the process flow of the one-step one-plate three-differential yarn spinning is completely consistent with the process flow of the spinning-drafting one-step FDY. The difference between the two is the design of the spinneret plate. Although each monofilament passes through the same spinning path, the structural and performance differences among the components can be changed through the design of the hole patterns and the hole diameters of different spinneret plates, and the three-different combined filament can be spun in one step. The process is characterized in that: the spinning method is suitable for spinning a high polymer raw material, different shrinkage mixed fiber composite yarns are spun by utilizing the difference of the aperture area and the aperture shape of the same spinneret plate, and the multifilaments with different titer are compounded together in the spinning process, so that the same spinning yarn path is realized, and the processing technology is completely the same. The method for reducing the diameter of different holes on the same board has small difference of the shrinkage rate among fibers, in order to achieve the fluffy style effect, the difference of the linear density of the thick and thin protofilaments needs to be enlarged, which has certain technical difficulty, when the linear density difference is large, the thin protofilaments are completely cooled, but the thick protofilaments are not completely cooled, when the thick protofilaments are contacted within 100cm away from a spinneret plate, the broken filaments often appear, but the difference of the thermal shrinkage performance generated by the difference of the fineness is limited, so that the problem of insufficient fluffy feeling of the different-shrinkage mixed-fiber composite yarn is caused.

The double-screw melting and plate-combining combined spinning method is characterized in that two same raw materials or different raw materials are respectively spun by a special spinning component designed in a meta-position mode through a double-screw extruder, and filaments spun by different spinneret plates pass through different spinning paths, so that the processing technologies of post-drawing, compounding and the like have larger differences. The high-shrinkage component is not drafted or drafted by low times, the low-shrinkage component is drafted by high times, the difference between the high molecular structures of the components is improved by matching with different spinning and drawing temperatures, setting temperature effects and the difference between the hole shape and the hole diameter of a spinneret plate in some processes, different thermal shrinkage performances are realized, the purpose of differential shrinkage is achieved, and finally the mixed filament yarn is compounded by processes of compounding, mixing, setting, networking and the like. The technical key of the process is that different components are subjected to different drafting to form different crystallinity and orientation degrees, so that the difference in the performance of the components is caused, and the differential shrinkage is realized. One or more sets of cold rollers are required to be added to the equipment. The method has certain flexibility in spinning, and can combine two polymers with larger shrinkage difference into a different shrinkage mixed fiber composite yarn with excellent different shrinkage, also can combine polymers with different dyeing properties into a mixed fiber yarn, so as to obtain the effect of same dyeing and different colors in dyeing, and also can combine the mixed fiber yarn with different section shapes. Therefore, the different shrinkage mixed fiber composite yarn manufactured by the method can reach a certain level in the degree of performance difference. However, this method has limitations, and the production equipment currently used for this method can produce only FDY/POY and one-to-two-component combined filament yarn, and FDY/FDY or multi-component combined filament yarn cannot be produced. In addition, in the existing spinning beam heat insulation system, the side blowing system, the oiling system and other key process control systems of the product production equipment, the FDY and POY components share one set of system, and can only be synchronously adjusted at the key process control points of the spinning beam temperature, the side blowing air speed, the oil frame height and the like, and the two bundles of yarns can not be respectively controlled, so that the adjustment space of the product performance is limited, the applicability of the equipment is narrow, and the development of the one-step method combined yarn is restricted.
