Description
Technical Field
The invention relates to the field of novel yarns, in particular to a production method of graphene chinlon and terylene vortex blended yarn.
Background
Vortex spinning is spinning equipment (MVS) which is developed by Murata company of Japan and is suitable for spinning pure cotton by improving air jet spinning (MJS). The spinning principle of vortex spinning is that sliver which finishes drawing is supplied to a drafting device, fiber bundles drafted by a roller drafting device are output from a front roller jaw and enter a spinning nozzle along a spiral fiber guide channel under the action of axial airflow at the inlet of the spinning nozzle. The outlet of the spiral fiber guide channel is provided with a needle-shaped twist-stopping piece, and the fiber bundle is bent at the needle part, so that the fiber bundle is introduced into the vortex chamber in a state of not adding twist. The leading end of the fiber bundle is drawn into a yarn passage in the spindle by the dragging action of the formed yarn and twisted into the newly formed yarn as a yarn core. The tail end of the fibre remains in the fibre guide channel while being gripped by the front roller nip. When the tail end of the fiber is not held by the front roller jaw any more, the tail end of the fiber is not kept in the fiber guide channel under the centrifugal action of the air vortex in the spinning nozzle, but is radially dispersed by the rotating airflow at the spindle inlet, is laid on the conical surface at the front end of the spindle under the driving of the air vortex, rotates along with the air vortex, is wound on the subsequent yarn and is output through the channel of the yarn in the spindle. The yarn formed is composed of a yarn core formed by approximately parallel untwisted fibers and fibers wrapped spirally on the periphery. The yarn formed and delivered is removed of yarn defects by an electric yarn cleaner and then wound on a bobbin. The fibers themselves receive different loads due to the difference in the sum of the residence time of the fibers in the nozzle and the energy density of the air jet. Thus, the characteristics of the yarn also change. The higher the speed, the softer the yarn and the lower the speed, the stiffer the yarn. Vortex spun yarns have the characteristics of being hard outside and soft inside.
Compared with ring spinning, vortex spinning has the advantages of high speed, high yield, short process flow, high yield, simple operation, convenient joint and the like. Production practices have shown that vortex spinning also has some limiting factors in the development process.
(1) The range of suitable spinning raw materials for vortex spinning is only limited to short chemical fibers and medium-long fibers, and the competitive power in the field of fine yarns is not strong due to the quality of finished yarns.
(2) The yarn forming structure of the vortex spinning is loose, the uniformity of long sections is good, the yarn evenness of the formed yarn is generally close to the level of ring yarn, but the thickness unevenness of extremely short sections is more remarkable than that of the ring yarn, but the strength is lower and unstable, and the development of the vortex spinning to the field of fine yarn is limited.
(3) Although the air vortex is used for replacing the rotor of the rotor spinning, the problems of abrasion caused by high-speed rotation of the rotor spinning and overlarge bearing load are solved, but the problems of larger centrifugal force and tension caused by the yarn arm formed when the free end yarn tail rotates in the vortex tube at high speed cannot be solved. And thus its spinning speed cannot be developed in a breakthrough manner.
(4) The resultant yarn of vortex spinning has too short coagulation process due to poor fiber straightness, so that the structure of the yarn is loose, the strength of the yarn is low, and the product is limited, and is only suitable for chemical fiber raw materials, products with low strength requirements such as spinning thick knitting yarns or thick napped yarns and the like, or core-spun yarns taking filaments as yarn cores.
Nevertheless, also with direct sliver-fed vortex spinning, there are conditions and possibilities to achieve a fully automated continuous production line. The method has the unique advantages of eliminating a roving frame, a spinning frame and an automatic winder, reducing the occupied area, the labor and the investment, and further replacing ring spinning and air flow yarns in the field of knitting yarns. Therefore, there is a need for further development to overcome the disadvantages and limitations of the prior art and to make the spinning process a new spinning process with unique features.

roller pairs is consistent to the conveying speed of the middle and front roller pairs under the action of the middle drafting zone, so that the speed change process of the fibers moving from slow speed to fast speed in the middle drafting zone is realized, the fibers slide mutually at the speed change, so that the density of the fed mixed fiber drawn sliver is reduced to obtain a second mixed fiber sliver, before the fibers in the first mixed fiber sliver are held by the middle and front roller pairs, the fibers in the first mixed fiber sliver are firstly contacted with a third control roller, at the moment, the tail end of the short polyester fiber is separated from the holding of the middle and rear roller pairs, so that the polyester fiber is in a floating state with two ends not controlled, when the head end of the polyester fiber in the floating state is in contact with the third control roller, the third control roller generates friction control force on the head end of the polyester fiber, so that the polyester fiber continues to be stably kept consistent with the conveying speed of the middle and rear roller pairs, and further the stable control of the polyester fiber in a middle drafting area is realized, at the moment, the tail end of the long graphene nylon fiber is still held by the middle and rear roller pairs, the third control roller generates friction

roller generates friction control force on the head end of the polyester fiber, so that the polyester fiber is converted from the conveying speed which is consistent with the middle-rear roller pair into the conveying speed which is consistent with the middle-front roller pair, and then the speed change process of the polyester fiber in the middle drafting area is realized, so that the linear density of the polyester fiber composition part in the first mixed fiber strand is reduced, at the moment, the tail end of the longer graphene polyamide fiber is still held by the middle-rear roller pair, when the head end of the graphene polyamide fiber in the holding controlled state is in contact with the fourth control roller, the fourth control roller generates friction control force on the head end of the graphene fiber, but the tail end of the graphene polyamide fiber is in the holding controlled state, thereby the fiber head end and the tail end of the graphene nylon generate speed difference, under the speed difference, the front hook of the fiber head end is enabled to be straightened, then the straightening degree of the graphene nylon fiber is improved, at the moment, the linear density of the polyester fiber component part with larger mixing proportion is reduced, the linear density of the graphene nylon component part with smaller mixing proportion still keeps the feeding state, so that the graphene nylon fiber further permeates into the polyester fiber, the mixing uniformity of the graphene nylon fiber and the polyester fiber is improved, then the polyester fiber is held by the middle front roller pair, the graphene nylon fiber is also held by the middle front roller pair, and at the moment, the tail end of the graphene nylon fiber is separated from the holding effect of the middle rear roller pair, thereby the conveying speed of the graphene nylon fiber, which is kept consistent with the middle rear roller pair, is changed into the conveying speed

the fed second mixed fiber strand to obtain the mixed fiber strand required by drafting, and the mixed fiber strand obtained by drafting is held and output by the front roller pair, the output mixed fiber strand then enters a yarn forming cup, at the moment, the mixed fiber strand firstly enters a twist stopping ring positioned at the top end of the yarn forming cup, the short-length polyester fiber directly enters a spinning channel to form a yarn core due to the fact that the tail end of the short-length polyester fiber is separated from the holding effect of a front roller pair under the effect of the twist stopping ring, meanwhile, the long-length graphene nylon fiber is still held by the front roller pair so that the length within 10% of the front fiber section also enters the spinning channel to form the yarn core, when the tail end of the graphene nylon fiber is separated from the front roller pair and held by the yarn forming cup under the effect of internal vortex centrifugation, the tail end of the long-length fiber of the graphene nylon fiber is laid down on a front end conical surface of the yarn forming cup, and the tail end of the short-length polyester
