Technical Field

[0002] With the development of social economy and the continuous improvement of people's living standards, people are paying more and more attention to the fashion and functionality of textiles used in clothing, in addition to the pursuit of wearing comfort, and are pursuing unique styles and various functions, such as antibacterial and antistatic functions.

[0003] In order to meet this demand of consumers, the continuous development of new yarns and fabrics has become an important task for the textile industry.

[0005] Nylon is a synthetic fiber with good elasticity and strength, excellent wear resistance, and good moisture absorption properties, so it has strong dyeability. Nylon modified with graphene can be used as raw material for yarn production.

[0006] However, the graphene modification technology is not yet perfect, and the modified nylon fiber still has shortcomings. Due to the strong interaction between the internal graphene, the dispersion of the graphene material is poor, resulting in a small surface friction coefficient of the graphene nylon fiber and poor cohesion between the fibers.

[0039] The present application relates to a method for producing antibacterial blended yarn, which is explained in detail below through specific implementation methods.

[0040] A method for producing antibacterial blended yarn, comprising: The selected cotton fibers are processed through a blowing and carding unit and combed to obtain combed slivers. A small portion of the cotton fibers that have been blown through the blowing and carding unit are distributed through the cotton distribution tee and then returned to the disc 3 of the graphene nylon fiber mixing and plucking machine through the cotton conveying pipeline 11, so as to be evenly mixed with the pre-treated graphene nylon fibers in the disc 3. At this time, the content of the cotton fibers is within 10%. The mixed graphene nylon and cotton fibers are processed through a blowing and carding unit and pre-drawing to obtain graphene nylon / cotton pre-drawing. The first mixing of graphene nylon fiber and cotton fiber effectively improves the problem that graphene nylon fiber is difficult to be formed into strips alone due to its low surface friction coefficient, which results in low holding force between fibers. Then, the combed cotton sliver and graphene nylon / cotton pre-drawing are drawn through three drawing passes to obtain mixed sliver. Then, the second mixing of graphene nylon fiber and cotton fiber achieves the required blending ratio of graphene nylon fiber and cotton fiber. The mixed sliver is then sequentially spun through coarse yarn and spun yarn to obtain the required antibacterial blended yarn. The specific steps include: Raw material selection: Select raw cotton fibers with moderate maturity, few neps, and average ginning. At the same time, they need to be blended with graphene nylon. Therefore, select raw cotton with good original color and few defects. Select graphene nylon fibers with fine fineness, long average length, and good length consistency, so that the number of fiber roots in the cross section of the blended yarn is large, which is conducive to enhancing the strength of the fibers in the yarn and the uniformity of the yarn. Select graphene nylon fibers with fineness close to that of cotton fibers and moderate oil content. Step 1: Graphene nylon fiber pretreatment: Due to the extremely strong internal force of the graphene layer, the force between the graphene-modified nylon fibers is greatly reduced, which makes the surface friction coefficient of the graphene nylon fiber small and the fiber surface smooth. It is not easy to separate into strips, which affects the further processing of the subsequent steps. The graphene nylon fiber is pretreated by mixing antistatic agent and warm water in a ratio of 1:6, and then evenly spraying the manually preliminarily opened graphene nylon with a sprayer and leaving it for 24 hours. The pretreated graphene nylon fiber is then stacked in a graphene nylon cotton storage box; Step 2: Blowing and carding: For the cotton blowing and carding, the selected raw cotton fibers are sequentially picked up by a reciprocating mixing plucker equipped with a TF27 bridge-type magnet according to the required mixing ratio. During the picking process, the raw cotton fibers are torn and loosened by the plucking beater 12, and the uniform mixing of various raw cotton fibers is achieved through the reciprocating movement of the plucking beater 12. The metal block impurities and sparks in the picked raw cotton fibers are separated and removed by the AMP3000V5 metal spark detector, and the block impurities in the raw cotton fibers are separated and removed by the TF50 heavy object separator. The single-axis flow cotton opening is performed with a FA051 condenser. The machine opens and removes impurities from the raw cotton fibers. The multi-bin cotton blender with 10 high-cotton bins fully mixes the raw cotton fibers, and the cotton fibers are opened and removed during the mixing process. The cotton cleaner deeply opens and removes impurities from the mixed cotton fibers. The JWF1054 type dust remover separates and removes fine impurities from the cotton fibers. The TF2202A type cotton distribution tee distributes the cotton fibers according to the required proportion. The cotton carding machine carefully opens, combs, removes impurities, and forms strips of cotton slivers, thereby producing strip-shaped cotton slivers. The cotton slivers are continuously coiled in the sliver can by the TF2513 type coiler. For the graphene nylon blowing and carding unit, the pretreated graphene nylon fiber and the cotton fiber treated in the blowing process of the blowing and carding unit are grabbed by a mixed cotton plucking machine, and the mixed cotton plucking machine includes a mixed cotton plucking machine; Step 3: Cotton combing: The combed cotton sliver obtained in the second step is directly processed through a sliver-winding machine to produce combed small rolls with a roll structure. The combed small rolls are then combed to separate and remove the short fibers in the cotton fibers, thereby producing combed cotton slivers with more uniform fiber length distribution. The E65 combing machine is used for combing. Step 4: Pre-drawing: The graphene nylon / cotton carded sliver prepared in the second step is pre-drawn to obtain a graphene nylon / cotton pre-drawn sliver with improved sliver evenness. During the pre-drawing process, six graphene nylon / cotton carded slivers are fed together, stretched and attenuated by the drafting system, and then re-drawn to obtain the graphene nylon / cotton pre-drawn sliver. Step 5: Mixed drawing: The graphene nylon / cotton pre-drawn sliver prepared in the fourth step and the combed cotton sliver prepared in the third step are drawn together through three drawing passes to obtain graphene nylon / cotton drawn sliver. In the first drawing pass, a total of 5-8 graphene nylon / cotton pre-drawn slivers and combed cotton slivers are fed together, and the specific quantity of the fed graphene nylon / cotton pre-drawn slivers and combed cotton slivers is determined based on the blending ratio of graphene nylon fiber to cotton fiber in the final blended yarn and the linear density of the spun graphene nylon / cotton pre-drawn slivers and combed cotton slivers. The fed graphene nylon / cotton pre-drawn slivers and combed cotton slivers are drawn and thinned by the drawing frame and then re-combined to obtain graphene nylon / cotton mixed slivers, thereby achieving The graphene nylon fiber and the cotton fiber are mixed according to the required mixing ratio. In the second drawing process, a total of 6 graphene nylon / cotton mixed drawing strips are fed together. The fed graphene nylon / cotton mixed strips are stretched and thinned by the drawing frame and then re-combined to obtain graphene nylon / cotton semi-cooked strips, thereby achieving a finer and more uniform mixing of the graphene nylon fiber and the cotton fiber. In the third drawing process, a total of 6 graphene nylon / cotton semi-cooked drawing strips are fed together. The fed graphene nylon / cotton semi-cooked strips are stretched and thinned by the drawing frame and then re-combined to obtain graphene nylon / cotton cooked strips, thereby achieving a finer and more uniform mixing of the graphene nylon fiber and the cotton fiber. Step 6: Roving: The graphene nylon / cotton sliver obtained in the sixth step is stretched and thinned by the drafting system of the roving frame and twisted and wound by the twisting system to obtain graphene nylon / cotton roving with a certain strength. The THC2015 automatic doffing roving frame is selected; Step 7: Spinning: The two graphene nylon / cotton rovings obtained in the seventh step are stretched and thinned by the drafting system of the spinning frame and twisted and wound by the twisting system to obtain a strong antibacterial blended yarn. The TH598 spinning frame is selected; A collecting device can be added to the front of the drafting system of the spinning frame.

They are stretched and thinned under the drafting action of the first drafting device, and then re-combined to obtain cotton pre-drawn slivers with improved sliver evenness. The obtained cotton pre-drawn slivers are then guided by the sliver guide plate and enter the second drafting device together to form a cotton web. After the cotton web is output, it is turned 90 degrees by the curved guide plate and pressed by its respective pressing rollers. The three cotton webs after pressing are combined at the pressing roller to obtain a cotton roll, which is then wound into the required small roll by the winding roller.

Along the radial direction of the connecting axis, the distribution density of the blades 16 on the cutter disc 15 gradually decreases from the outside to the inside. The cotton feeding jacket 9 is a hollow structure, the upper and lower ends of the cotton feeding jacket 9 are open, the cross section of the cotton feeding jacket 9 is rectangular, and the cross section area of ​​the cotton feeding jacket 9 gradually increases from top to bottom along the height direction of the cotton feeding jacket 9.

[0046] The rotating shaft 5 includes: A sleeve 51 is sleeved on the column 41 and is in the shape of an I-shaped wheel.

[0048] When in use, the second motor 53 drives the shaft ring 52 of the rotating shaft 5 to rotate, thereby moving the cotton picking device away from the graphene nylon conveying pipeline 8 and the cotton conveying pipeline 7, and the third motor 43 drives the rotating shaft 5 to rise to the highest point, and then the first motor drives the chassis 2 to rotate, and then drives the disc 3 to rotate synchronously. During this process, the first cotton conveying fan in the cotton conveying pipeline 7 drives the cotton fibers that have been opened and cleaned to be continuously transported from the cotton conveying pipeline 7 to the mixed cotton picking machine of the mixed cotton picking machine. At the same time, the second cotton conveying fan in the graphene nylon conveying pipeline 8 drives the pre-treated graphene nylon fibers to be continuously transported from the cotton conveying pipeline 7 to the mixed cotton picking machine of the mixed cotton picking machine.

On the other hand, the rotation of the mixed cotton picking machine realizes the mixing of graphene nylon fiber and cotton fiber in the mixing. The uniform layer mixing in the mixed cotton plucking machine is achieved, and then the mixing effect of the two fibers is improved. When the fibers fill the mixed cotton plucking machine, the second cotton feeding fan and the second cotton feeding fan stop working, and at this time the corresponding one of the TF2202A type cotton feeding tee in the cotton cleaning and carding unit also stops feeding cotton, and then the third motor 43 drives the rotating shaft 5 to descend until the fibers in the mixed cotton plucking machine are pressed by the ribs 10, and the fourth motor drives the connecting sleeve 14 to rotate along the intermediate shaft 13, and then drives the blade 16 of the knife disc 15 on the connecting sleeve 14 to rotate, and the blade 16 rotates to grab the fibers that are pressed and extend into the ribs 10, and in the grabbing process, the fibers are initially loosened by the tearing effect of the blade 16 on the fibers. At the same time, the second motor 53 drives the shaft ring 52 of the rotating shaft 5 to rotate along the connecting column 4, and then drives the cotton plucking device to rotate along the circumferential direction of the mixed cotton plucking machine, so that the cotton plucking beater 12 can grab the fibers at different positions in the mixed cotton plucking machine, thereby achieving initial mixing of the fibers; At this time, the first motor is kept driving the chassis 2 to rotate, and then the disc 3 is driven to rotate synchronously, and the rotation direction of the chassis 2 is opposite to the rotation direction of the shaft sleeve 51, thereby driving the fibers in the mixed cotton plucking machine and the cotton plucking beater 12 to rotate in opposite directions, and then the blades 16 in the cotton plucking beater 12 are in contact with the fibers in relative motion, thereby effectively reducing the rotation speed of the cotton plucking device while maintaining the cotton plucking speed (if the fibers in the mixed cotton plucking machine and the cotton plucking beater 12 rotate in the same direction, the rotation speed of the cotton plucking beater 12 needs to exceed the rotation speed of the chassis 2, and when the present application rotates in the opposite direction, there is no need for the rotation speed to be too high), thereby improving the service life of the cotton plucking beater 12, and on the other hand, the relative motion contact between the blades 16 of the cotton plucking beater 12 and the fibers enables efficient fiber opening while maintaining a low rotation speed of the cotton plucking beater 12, thereby effectively reducing the damage to the fibers by the blades 16, The grabbed graphene nylon fiber and cotton fiber are transported to the AMP3000V5 metal spark detector through the upper port of the cotton conveying jacket 9 by the cotton conveying pipeline 11, so as to separate and remove the metal block impurities and sparks in the grabbed fibers, separate and remove the block impurities in the fibers by the TF45B heavy object separator, and fully mix the cotton fiber and graphene nylon fiber by a multi-bin cotton mixer with 10 high cotton bins, and realize the opening and impurity removal of the fibers during the mixing process, and perform in-depth opening and impurity removal on the mixed fibers by a cotton cleaning machine equipped with a FA051A condenser, and then driven by the ZF9104-500 conveying fan, the mixed fibers are carefully opened, combed, impurity-removed, and formed into strips by a cotton combing machine, thereby producing strip-shaped graphene nylon / cotton combed slivers, which are continuously coiled in the sliver can by the TF2513 coiler.

[0049] Taking the preparation of compact siro-spun antibacterial blended yarn with a linear density of 40S and a blending ratio of GN40 / JC60 as an example, the combed cotton strips are torn and then mixed with the graphene nylon, and the cotton fibers after opening and cleaning are mixed with the graphene nylon in this application, and the combed cotton strips are torn and then mixed with the graphene nylon, and the cotton fibers after opening and cleaning are mixed with the graphene nylon in this patent. The mixing ratio of cotton fibers is 5%. For convenience, the two methods are respectively recorded as combed mixing and opening and cleaning mixing in the following analysis. The corresponding processing processes are shown in the attached figure. Figure 4-10 : According to the attached Figure 11-13 The test results show that compared with the method of tearing combed cotton slivers and then mixing them with graphene nylon, the method of this patent mixes the cotton fibers after opening and cleaning with graphene nylon, which effectively avoids the damage to the cotton fibers during the two combing treatments, thereby improving the strength and strength unevenness of the yarn; at the same time, the yarn defects of the yarn, mainly thick places and thin places, are reduced.

[0050] At the same time, compared with the traditional method of tearing combed cotton strips and then mixing them with graphene nylon, the mixing efficiency is greatly improved.
