Detailed Description
In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.
The covering yarn is a spinning process for uniformly wrapping a core yarn after being drafted when the core yarn passes through a spindle with an outer covering yarn bobbin, and two process characteristics of spinning the covering yarn, namely drafting multiplying power and covering density (namely twist), are introduced.
The draft magnification (D/R) is the ratio of the linear velocity of the draft rollers to the linear velocity of the feed rollers at the same time, and is set according to the elastic quantity required for processing.
The twist (indicated by T/M) is the number of turns of the outer covering yarn per meter on the drawn core yarn, is inversely proportional to the spinning speed and is directly proportional to the spindle speed, and can be expressed by the following relation: twist (T/M) = spindle speed (RPM)/drawing line speed (M/MIN).
Referring to fig. 1, the embodiment of the covering yarn machine with double-drafting structure of the present invention includes a frame, and a feeding mechanism, a yarn covering mechanism, a drafting structure, a winding mechanism and a transmission mechanism mounted on the frame, it is characterized in that the feeding mechanism comprises a feeding wheel 21 and a feeding roller 22 which drive the core wire 1 to rotate, the yarn wrapping mechanism comprises a bobbin 32 and a spindle 31 driving the bobbin to rotate, the spindle 31 of the yarn wrapping mechanism is in transmission connection with the transmission mechanism, the two drafting structures are arranged from bottom to top along the core wire transfer direction and are respectively a first drafting structure 42 and a second drafting structure 41, each drafting structure comprises a drafting roller and a pressing roller which are matched with each other, the drafting rollers of the first drafting structure 42 and the second drafting structure 41 are respectively provided with different drafting multiplying powers, and the coiling mechanism comprises a coiling wheel 51 and a coiling assembly 52 which are matched with each other. The utility model discloses the draft roller of upper and lower draft structure sets up different draft multiplying powers respectively, and different draft multiplying powers must produce the pulling force to middle core silk, will make the core silk fracture if the pulling force is enough big, so can realize underfeed draft technology through the settlement of upper and lower draft structure draft multiplying power, through adopting cladding-super draft technology in the course of working, breaks the core silk by force, makes middle spandex be the disconnection of irregular length distance, and the place that is formed with has the spandex, and there is not the spandex in some places. There is elastic shrinkage in some places and no elastic shrinkage in some places on the same covering yarn. The fabric woven by the wrapping yarn forms irregular folds on the surface of the fabric. The appearance style of the fabric is similar to wrinkle and non-wrinkle, similar to hemp and non-hemp, and is a substitute product for the common elastic fabric.
Drafting multiplying power: in the process, the selection of the drafting multiplying power of the ammonia-breaking covered yarn is a key, and the selection is determined according to the denier of spandex, the elastic elongation performance and the specific test of the covered fiber raw material, and generally can be about 10 percent lower than the breaking elongation value of the spandex, and is as large as possible under the condition of not breaking the spandex in principle.
Through the experiment of 40D spandex, the draft multiplying factor of the coated filament is selected from 4.0-5.5, the short fiber is selected from 3.5-4.5, and the double coating of the short fiber and the extended filament is selected from 3.5-5.0; the selection of 70D spandex is 5-6. Because the domestic spandex is low in elastic extension, the drafting multiplying power is set to be lower, the elastic extension of the imported spandex is larger, the drafting multiplying power is set to be higher, the numerical value of different manufacturers is also greatly different, the product is 40D domestic spandex double-covered yarn, and the finally determined drafting multiplying power is 4.5. Namely, the draft magnification of the first draft structure is set to 3.5 to 6.
Coating degree (twist): an important process parameter of mechanically covered yarns is twist, which affects yarn quality, tenacity and evenness. The twist is increased, so that the cohesive force between the outer-coated fiber and the spandex silk can be increased, and the strength of the coated yarn is improved. The twist is too low, the wrapping fiber is loose, the wrapping effect is influenced, and the core exposure phenomenon occurs, so the twist is higher during mechanical wrapping. However, the twist is too high, the fabric feels hard, and the drapability is poor. Generally, the twist is adjusted according to the change of the denier of the yarn and the different style requirements of the fabric. The elongation of the machine bag is mainly determined by the performance of spandex core yarn, the twist is too large, the outer layer fiber is covered too tightly, the elastic effect of the spandex yarn cannot be fully exerted, and the elongation is reduced. As twist increases, evenness of the yarn improves. The twist is too small, the covering fiber is loose, and the fiber moves slightly along the axial direction of the yarn due to friction and the like in the spinning process, so the yarn evenness is deteriorated.
According to our production practice, the twist of the yarn is chosen between 450T/m and 550T/m, the twist of the yarn is chosen between 500T/m and 550T/m, and the twist of the yarn is chosen between 500T/m and 600T/m. The product is double-coated by cotton and polyester filament, and the twist selected by the test is 570T/m. Namely, when the yarn tube of the yarn wrapping mechanism is provided with filaments, the ratio of the rotating speed of the spindle of the yarn wrapping mechanism to the drafting linear speed of the first drafting structure is 450-; when the yarn tube of the yarn wrapping mechanism is short fibers, the ratio of the rotating speed of the spindle of the yarn wrapping mechanism to the drafting linear speed of the first drafting structure is 500-; when the yarn tube of the yarn wrapping mechanism is provided with filaments and short fibers, the ratio of the rotating speed of the spindle of the yarn wrapping mechanism to the drafting linear speed of the first drafting structure is 500-600.
The selection of the super-drafting fold is also very important in the process, the value is generally about 1.15 times of the value of the first drafting fold determined in the prior art, and the ideal drafting fold ensures that the break point interval of the spandex is between 5 and 20 cm. The drafting multiple is too small, the spandex is not pulled to be broken or the breaking point is less, and the effect which the broken spandex covered yarn fabric should have cannot be achieved; too large draft multiple will cause too small break point interval, bad wrinkling effect, decreased elasticity of the fabric, and affect the wearability. The drafting multiple 40D of the step is determined to be about 1.15 times of the first drafting, 70D is determined to be about 1.18 times of the first drafting, the breaking point interval of spandex is 7-18cm, and the effect is good after the spandex is woven into the fabric.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
