Description
MACHINE DEVELOPED FOR THE PRODUCTION OF FLOCKED VELVET-LOOKING YARN AND FLOCKED VELVET-LOOKING YARN PRODUCED WITH THIS MACHINE
Technical Field Related To The Invention
The present invention relates to a machine developed for the production of flocked velvet-looking yarn, especially used in the textile industry and also in the aircraft industry - automotive, shoe-bag, and clothing sectors, and the flocked velvet-looking yarn produced with this machine and the flocked velvet-looking yarn production method. Flocked velvet looking yarns produced with the machine and method developed with this invention can be used in the form of woven, knitted, furnishing and clothing fabric, tulle, cord, packaging, knitwear, hand-knitted and flexible rubber, or n the production of different products according to different processes, toy and decoration industries, and in the production of products, such as mask band, etc. in different industrial fields due to the production of flexible yarn covered with natural latex flock.
The State of Art Related To The Invention
In the prior art, the production of flocked velvet-looking yarn is available. The patent applications determined for the production of flocked velvet-looking yarn are listed below.
US 4727664 (Application Date 18.10.1985, Publication Date 16.02.1988)
Patent publication numbered US 4727664 describes "a method and apparatus for producing a yarn or yarn-like material by electrostatically flocking or coating with fibers". In the method described in the publication, the grounded base or carrier yarns provided with adhesive are moved across an electrostatic high-voltage area, wherein the surfaces of the carrier yarns are surrounded on all sides by pre-treated short fibers (flock material). During the production of the yarn or flocked velvet-looking yarn, the selective lengths of the carrier yarns are non-homogeneously flocked in an irregular row with the flock material in different flock patterns.
The invention disclosed in the patent numbered US 4727664 is based on the principle of changing the operating parameters of the electrostatic system, but this method is inadequate for the production of flocked velvet-looking yarn for the reasons explained below.
The disadvantages of the invention disclosed in the patent numbered US 4727664 are that the pile density is insufficient, the friction and spalling strength of the flocks on the surface of the yarn is low, the flocks do not adhere sufficiently and the flocks are easy to be stripped. As a result, the invention disclosed in this patent is not a suitable production technique for flock yarn, and further disadvantages are its low productivity and not being suitable for industrial production.
• TR 2008/08141 (Application Date 28.10.2008, Publication Date 21.07.2009)
In patent publication numbered TR 2008/08141 , the sample production machine developed for flocking and drying materials such as yarn, roving, cord, etc. with flat or fancy effects is explained. The present invention relates to a multi-functional production line for the production of flocked velvet-looking yarn, roving, cord, and ribbon on the same line.
The invention described in the patent publication numbered TR 2008/08141 is characterized by the application of the adhesive (flock glue) layer on the carrier material, the stuck of the flock fibers on the adhesive coating by electrostatic method, the drying and fixation of the flocked material in the dryer, the cooling of the hot material, the removal of non-adherent flocks by brushing and suction, and the obtained products are formed in suitable forms and by wrapping.
The disadvantages of the invention described in the patent numbered TR 2008/08141 are the low amount of pile due to the non-adhesion of the yarn, the low friction and spalling strength, the deviation of the number variance due to the yarn tensions, and the inability to perform the continuity and smooth yarn flocking, as well as the low productivity and not being suitable for industrial production.
• TR 2010/04301 (Application Date 28.05.2010, Publication Date 21.02.2011)
The invention disclosed in the patent publication numbered TR 2010/04301 relates to the adhesive application unit of a machine developed for flocking textile materials with circular cross-sections such as yarn, roving, and cord by electrostatic flocking technique. A sample application unit provides a homogeneous and cylindrical adhesive coating of
the surface of the material in the smooth and perfect flocking of the cylindrical carrier materials developed with the invention.
With this developed adhesive application unit, the adhesive application can be made to the entire surface of the carrier materials in the form of yarn, roving, and cord in a 360° homogenous manner.
In the adhesive application unit of the invention disclosed in the patent publication numbered TR 2010/04301 , the cylinder rotates inside the adhesive chamber and the stripping blade is used.
In the invention of this patent application, in the adhesive application unit, the cylinder does not rotate in the adhesive chamber, and the stripping blade is not used. In addition to this, in the invention of this patent application, there are channels in both cylinders used vertically and this vertical cylinder system is used for flocking yarns with a special thickness (yarn diameter 1-10 mm).
In the invention of this patent application, the adhesive is given by automatic dosing in front of the cylinders operated horizontally and on the vertical axis. This causes the adhesive to be coated on the yarn uniformly without changing the viscosity of the adhesive. In the invention described in the patent publication numbered TR 2010/04301 , the adhesive left in the adhesive chamber for too long will cause viscosity changes and will not be uniformly coated on the yarn, so the patent numbered TR 2010/04301 is very difficult to be applied to the industry.
In the invention of this patent application, the speeds of the cylinders used horizontally and vertically are changed according to the line speed, and the adhesive is coated on the yarn more or less uniformly at all times. This important feature is not disclosed in patent publication numbered 2010/04301.
Pressure applications to one of the cylinders used horizontally and vertically with the pressure piston enable the cylinders to rotate easily and thus the adhesive is spread on the yarn uniformly. Also, this important feature is not disclosed in patent publication numbered 2010/04301.
In the invention disclosed in the patent publication numbered 2010/04301 , the re stripping of the yarn with adhesive from the cylinders from the porcelain guide will disturb the homogeneity of the adhesive that should be spread on the yarn homogeneously, thus making the application of the system to the industry very difficult.
• TR 2016/10476 (Application Date 27.07.2016, Publication Date 21.02.2018)
In patent publication TR 2016/10476, "a fancy flock spinning machine is described with an adhesive application unit comprising a glue trough and an application cylinder provided in said glue trough." The machine comprises at least one directing cylinder provided around the adhesive vessel, which provides up and down movement in the x-direction to determine the contact degree of the carrier materials with said application cylinder. The machine of the present invention is a sample flocking machine operating at low speed.
The disadvantages of the invention described in the patent publication numbered TR 2016/10476 are that in this patent publication, both cylinders are inside the adhesive chamber and are stripped off with a blade. As this will break the viscosity standards of the adhesive, its application to the industry becomes very difficult.
In the invention of this patent application, the adhesive is given between two cylinders in a controllable amount by an automatic dosing system, and it is plastered on the yarn without breaking the viscosity standards of the adhesive and sent to the flocking unit.
In the invention of this patent application, it is possible to transfer the adhesive onto the yarn by driving the cylinders operating in the horizontal and vertical axis at different speeds according to the line speed to plaster the adhesive on yarns of different thicknesses.
The flocked velvet-looking yarns produced by the machine and method developed with the invention of this patent application are in accordance with the high standards of the flocked yarns produced according to the state of the art in the above-mentioned publications of the prior art and have efficient and industrially applicable properties.
The Aim of the Invention
In this invention, it is aimed to develop a machine for the production of flocked velvet-looking yarn and a flocked velvet-looking yarn production method. Through the machine and production method developed with this invention, it is also aimed to produce flocked velvet-looking yarns, which have a commercial value, in industrial sizes and to produce fancy fabrics with flocked velvet-looking yarn developed with this invention.
In this invention, it is also aimed to develop different fancy yarns that are flocked with materials such as cord, ribbon, glitter, spangle, sequin, beads, etc.
With this invention, flocked velvet-looking yarn with different NM (number metric) properties can be produced. Here, NM values may change according to the flock type and
root yarn number to be used. The flock type and root yarn number may change according to the current yarn in the market and customer demand.
NM (Number metric) is the unit of measurement used in the yarn and is indicated by the fineness and thickness numbers of the yarns. Numbering is performed with the amount of length per a certain weight. For example, the number of yarn of 0.310 grams per meter is expressed as Nm 3.2.
It is aimed to produce yarns, which have a good touch, high strength, high abrasion, tearing, and tensile strength compared to similar yarns in the market, from the yarns obtained by the machine and production method developed with this invention.
Regarding the sample machines which are low and inadequate in terms of speed, capacity, and quality, that are described in patent application numbered US 4727664 and domestic TR 2008/08141, TR 2010/04301, TR 2016/10476 patents, which are targeted in this invention, it is aimed to develop the production machine and method that can serve different textile sectors by having very high production capacity and being capable of various coating processes. The flocked velvet-looking yarn production line developed with this invention creates flock yarn by flocking 60-120 yarns at the same time, and it is aimed to produce an average of 20-35 tons/month of production capacity.
In terms of quality, the high rubbing fastness and tensile strength of the flocked velvet-looking yarn and woven fabric are found to be much better than the equivalent productions described in the prior art patents. It is also much better in terms of pile density and touching.

Detailed Description of the Invention
The machine developed with this invention for the production of flocked velvet looking yarn includes the following units as main units.
• Yarn entry and tension adjustment unit (A),
• Adhesive application unit (B),
- Adhesive dispensing cylinder group (Bl) placed on the horizontal axis (for 1-6 Nm flocked yarn applications)
- Adhesive dispensing cylinder group (B2) placed on the vertical axis (for yarn applications with a diameter of 1-10 mm and special thickness)
• Flocking unit (C),
- Static energy loading with the conductive table in flocking (Cl)
- Static energy loading on the adhesive in front of the cylinders (C2)
- Down-feeding of the flock to coated yarns in flocking unit (C3)
• Drying unit (D)
• Fixator unit (F)
• Accumulator unit (F)
• Butterfly roller winding unit (G)
• Rollers unit (FI)
Yarn entry and tension adjustment unit (A) is the unit that provides the feeding of the yarn (1) coming from the yarn creel (0) to be flocked to the machine. This unit includes the yarn entry tension pressure cylinder group (2), the yarn entry tension group (3), and the yarn centering and guiding cylinders (4).
There are channels as many yarns as desired on the horizontal adhesive dispensing cylinder group (5) and vertical adhesive dispensing cylinder group (50- The number of channels varies according to the number of yarns to be flocked. horizontal adhesive dispensing cylinder group (5) are cylinders positioned/placed side by side on the same axis and rotating opposite to each other. Vertical adhesive dispensing cylinder group (5') are oppositely rotating cylinders positioned on top of each other on the vertical axis.
In the adhesive dispensing process, the channel depth (6), the channel width (7), the distance (8) between the channels (8) of the cylinders and the full cylinder length (9) and
the cylinder diameter (10) can be designed according to the thickness of the yarn (1-6 Nm feature or 1 - 10 diameter) to be used for the flocked velvet-looking yarn to be produced.
These measures/dimensions are located in the horizontal (5) and vertical (5') axes in the adhesive dispensing cylinder group, one cylinder on the horizontal axis have a channel, the other cylinder is straight and does not have a channel, and both cylinders on the vertical axis have channels. Since the adhesive dispensing cylinders (5') on the vertical axis are channeled, it is ensured that the whole surface of the yarn (1) with a diameter of 1-10 mm is completely covered with adhesive (12) while it passes between the cylinders. The reason for the fact that one of the adhesive dispensing cylinders (5) on the horizontal axis is channeled and the other is straight and without channels is that the yarn (1) to be surface-coated with adhesive (12) with these cylinders (5) is thinner (1-6 Nm). Thus, it is sufficient for a single cylinder to be channeled to completely cover the surface of 1-6 Nm yarn with adhesive (12).
The machine for the production of flocked velvet-looking yarn developed with this invention, the flocked velvet-looking yarn produced with this machine, and the adhesive dispensing cylinder groups used in the flocked velvet-looking yarn production method, both horizontal and vertical adhesive dispensing cylinder group (5) and the channel depth (6) of the cylinders can be between 0.4 and 2 mm, channel width (7) can be between 0.5 and 2 mm, the distance between channels (8) can be between 8 and 20 mm, length of cylinders (9)can be between 1500 and 2000 mm, cylinder diameter (10) can be between 200 and 300 mm, the radius of the channel corner (11) can be between 0.4 and 2 mm.
The adhesive application unit (B; B1-B2) is the unit that enables adhesive to be applied on the yarns whose surface will be flocked, this unit includes the yarn entry tension group (3), yarn centering and guiding cylinder (4), the adhesive dispensing cylinder group (5) on the horizontal axis for flock coating off and the adhesive- Nm yarns and adhesive dispensing cylinder group (5') on the vertical axis for flock coating of yarns with a diameter of 1-10 mm, the adhesive (12), the adhesive feeding nozzle (14) and the pressure piston (15). The surface of the yarn coming out of the adhesive application unit (B; B1-B2) is covered (13) with adhesive. In the adhesive application unit (B; B1-B2), different from the prior art applications, adhesive (12) is applied to the yarn (1) by adhesive dispensing cylinder group positioned in the horizontal axis (5) for flock coating of 1-6 Nm yarns and in the vertical (5') axis for flock coating of yarns with a diameter of 1-10 mm.
The adhesive application unit (B) is the unit that enables the application of adhesive (12) on the yarns (1) whose surface will be flocked. Adhesive application unit (B) comprises;
• Adhesive dispensing cylinder group (Bl) (5) positioned on the horizontal axis for 1-6 Nm flocked yarn applications, and/or
• Adhesive dispensing cylinder group (B2) (5') placed on the vertical axis for yarn applications with a diameter of 1-10 mm and special thickness.
Depending on the above-mentioned properties and thickness of the yarn whose surface will be flocked, the adhesive dispensing cylinder group (5) in the horizontal axis or the adhesive dispensing cylinder group (5') in the vertical axis is used in the adhesive application unit (B).
As can be seen in Figure 2, Figure Bl, and Bl DETAIL figures, the adhesive (12) is transmitted between the cylinders in the adhesive dispensing cylinder group (Bl) (5) placed on the horizontal axis through the adhesive feeding nozzle (14). While the cylinders (5), one of which is channeled and the other flat, rotate in opposite directions to each other, the adhesive (12) fills into the channels of the cylinder whose surface is channeled. 1-6 Nm of yarn (1), whose surface will be flocked, passes through the entry tension pressure cylinder group (2), yarn entry tension group (3) and yarn centering and guiding cylinder and its surface passes through the channel of the channeled cylinder, the whole surface of the yarn (1) is coated with the adhesive (12). Thus, 1-6 Nm of yarn (13) whose whole surface is coated with an adhesive (12) moves to the flocking unit to be surface-flocked.
As can be seen in Figure 2, Figure B2, and B2 DETAIL figures, the adhesive (12) is transmitted between the cylinders in the adhesive dispensing cylinder group (B2) (5') placed on the vertical axis through the adhesive feeding nozzle (14). While the cylinders (5'), both of which are channeled, rotate in opposite directions to each other, the adhesive (12) fills into the channels of the cylinders. The yarn (1) with a diameter of 1-10 mm, whose surface will be flocked, passes through the entry tension pressure cylinder group (2), yarn entry tension group (3), and yarn centering and guiding cylinder and its surface passes through the channels of the channeled cylinders, the whole surface of the yarn (1) is coated with the adhesive (12). Thus, the yarn (13) with a diameter of 1-10 mm whose whole surface is coated with an adhesive (12) moves to the flocking unit to be surface-flocked.
The amount of adhesive transferred on the yarn is adjusted by decreasing or increasing the rotation speed of the horizontal and vertical cylinders according to the line speed (movement speed of the yarn) and the viscosity of the adhesive as required. In other words, in the machine and flocked velvet-looking yarn production method developed within the scope of this invention, the rotation speed of the cylinders (5 and 5') positioned on the horizontal and vertical axis can be increased and reduced according to the line speed (the
movement speed of the yam) and the viscosity of the adhesive Due to this feature, the entire surface of the yarn is covered with the same thickness of adhesive and as a result, the entire surface of the yarn is covered with the same thickness of flock.
Differently from the prior art, in the machine and production method for the production of flocked velvet-looking yarn developed with this invention, the adhesive (12) is automatically dosed to the surface of the yarn (1) through the channeled and non-channeled cylinders of the horizontal axis (5) and vertical axis (5') adhesive group and the adhesive is homogeneously coated on the yarn, with the help of pistons and by giving a controllable amount of adhesive (12) through the adhesive feeding nozzle (14). Also, in this invention, by loading energy to the adhesive, a homogeneous flock coating is achieved by coating the adhesive loaded with energy on the yarn/surface.
The adhesive dispensing cylinder group positioned in the horizontal axis (5) and vertical (5') axis is preferably made of metal, copper, aluminum, carbon steel, or preferably stainless steel. The reason for this is to prevent deteriorating the yarn structure and the quality of the yarns due to rapid abrasion, chemical corrosion pilling, rupture, and similar reasons.
In the adhesive dispensing cylinder group positioned on the horizontal axis (5) and the vertical axis (5'), the surface of one of the cylinders (5) positioned on the horizontal axis is channeled and the surface of the other is flat, and both cylinders are rotated/operated in opposite directions and a controllable amount of adhesive (12) is reinforced to the channels between with the method of automatic dosing. While the yarns (1) to be covered with flock pass through the channels between the surfaces of these cylinders, the chemical adhesive (12) is transferred to the surface of the yarn (1).
In horizontal (5) and vertical (5') axes, the process is applied in such a way that the entire surface of the yarn (1) entering into the channels on the surface of the cylinders in the cylinder group is covered with adhesive.
Both of the cylinders (5') operating on the vertical axis are channeled and rotated in opposite directions to each other, the yarns with a special thickness (Diameter: 1-10 mm) are passed through these channels, giving adhesive (12) homogeneously to all sides (entire surface) of the yarn (1).
The aim is to provide the service of coating the surface of yarns/threads with special thickness with a flock in different fields, such as shoe or sweatpants, hand knitting, etc., depending on the demand.
The task of the flocking unit (C; C1-C2-C3) is to ensure that the yarns (13) covered with adhesive (12) on the surface in the adhesive application unit (B) are covered with flock. For Cl in the flocking unit; (C; C1-C2-C3) on the yarn (1), the flocks fed from the upper flock dosing chamber (20) flow neutrally from the brushed flock chamber (21), the grounding is performed via the static wire (22) located under the brush chamber, (-) energy is loaded by pouring on the conductive table (24) energized with a high voltage under the yarn with (-) load and on the brushed stripping conveyor (23) and flock filaments loaded with (-) energy is stuck onto the yarn (13) covered with the conductive adhesive (12).
In the prior art, high voltage (-) energy is supplied to the brushed flock chamber above (on the upper part), and flocking is performed in this way. In the machine and method developed with this invention, flocking is not performed in this way.
In this invention, unlike the prior art, (-) energy is loaded on the conductive table (24) energized with high voltage at the lower part and also on the adhesive (12).
For C2 in the flocking unit; process elements and steps are applied in the same way with the Cl unit, but only in the C2 unit flocking process, copper bar (27) is placed inside the adhesive (12) in front of the adhesive dispensing cylinders and (-) energy is applied with high voltage, thereby the yarn (13') covered with static (-) energetic adhesive is obtained and then flocking is performed.
The copper bar (27) is 1500-2000 mm long, 3-10 mm thick, 20-80 mm wide, and the copper bar (27) is placed inside the adhesive (12), and by loading (-) energy, as a yarn covered with adhesive becomes (-) loaded. In this way, a (-) load is given to the adhesive (12) and thus the yarn with the copper bar.
For C3 in the flocking unit, unlike the other two methods (Cl and C2), flocks are fed to the flocking unit under the adhesive coated yarns (13), the flock is transferred (21) from the flock chambers to the used conveyor belt (25), these flocks are transported to the flocking unit by the rotating flock feeding conveyor belt (25) through the high-voltage energized conductive table (24) under the yarns and the flocks are stuck on the adhesive- coated yarn (13). The free flocks remaining on the belt are removed from the environment with the suction nozzle (26) and fed back to the line.
To collect and use the flocks which are not used (which have not adhered to the adhesive on the yarn surface) in the machine and production method for the production of flocked velvet-looking yarn developed with this invention, the conveyor sweeping system includes the conveyor brush (23), the flock return chamber (16) and the flock feedback fan
(17) to sweep the flocks remaining on the energized conductive table (24) at the bottom. At the lower part (at the bottom), the unused (not adhered to the adhesive on the yarn surface) flocks remaining on the energized conductive table (24) are swept by the conveyor brush (23) and vacuumed by the flock return chamber (16) carriers and the flock feedback fan (17) and is transmitted to the feedback cyclones (18), wherein the collected flocks are used again. The conveyor sweeping system developed within the scope of this invention is not included in the prior art.
In the machine and production method for the production of flocked velvet-looking yarn developed with this invention, energy is given directly to the adhesive in the unit where the adhesive is transferred to the yarn in high voltage (-) static energy use. Through the conductivity of the adhesive, when the adhesive applied on the yarn enters the flocking unit with a static energy load, the neutral flocks poured from the flock chamber from above adhere to the adhesive on the yarn by charging the parallel voltage current of static energy.
In the flocking unit (C), generators supply (-) load to different materials. The conductive table (24) is loaded with a (-) load with the conductive adhesive (12) and the flock (-), like the copper bar (27). Since flock and adhesive are conductive, they create gravity (to yarn, adhesive, etc.) in the static field in (-) loaded environment.
Flocking unit;
In Cl, the flock is fed from the top,
In C3, it is fed from the bottom with a conveyor belt. As the table is (-) loaded, the flock contacts the table and is (-) loaded, then the conductive adhesive moves towards the coated yarn and gets stuck,
Since the direct adhesive is (-) loaded in C2, conductive flocks move towards and stick on the yarn.
The flocking process in 3 different flocking techniques is briefly explained below.
• Flocks (neutral) are uncharged but conductive, and the adhesive is also conductive and uncharged.
• In Cl, by applying (-) load on the table under the yarns, flocks flowing from above free neutrally and conductively move towards the yarns as the yarns and the adhesive are
conductive, and since the flocks contact the (-) loaded table, the conductive flocks are (-) loaded.
• In Cl, flocks flowing from above as neutral and conductive, the copper bar in the adhesive unit is (-) loaded and the yarn passing through the adhesive is covered with (-) loaded adhesive, while the (-) loaded adhesive covered yarn passes through the free- flowing conductive flocks from the flocking unit, it is stuck on the adhesive coated (-) loaded yarn.
• Unlike Cl and C2, in C3, the flock feeding is fed over the conveyor belt located under the yarns, wherein the flock is also neutral and conductive. Similar to Cl, the table under the yarns is (-) loaded and since the free flocks on the belt have (-) loads on the table, the adhesive will move towards the coated conductive yarn and become stuck.
In brief,
In Cl and C3, (-) load is given to the table, in C2, a static field is created by energizing the copper bar inside the adhesive with (-) load, the conductive flock is loaded with (-) load by contacting the plate and (in Cl and C3) by moving towards the adhesive coated conductive yarn, the flock becomes stuck in the yarn, since (-) load is given to the adhesive in C2, the adhesive becomes (-) loaded, and the flocks flowing freely and conductively from the upper side are thus directed towards the (-) load, that is, towards the adhesive-coated yarn and stuck on the yarn.
This flocking method has been developed with the present invention and is not included in the prior art. With this method, all sides of the yarn are covered with a flock equally.
Through this method, the flock is coated on the yarn faster, which increases the flocking speed, quality, and efficiency.
In this invention, flocked yarn is produced under the standards from the beginning to the end during the production.
Drying unit (D) is the unit where the drying process is applied at a certain temperature and time to dry the flocked yarn after the flocking process is applied to the adhesive-coated yarn (13) or the (-) energetic coated yarn (13'). The drying unit (D) is used to keep the flocked yarn therein for a long time and to ensure an efficient drying process.
Fixator unit (E) is the unit that increases the unshrinkability of the yarn and the strength of the yarn by rapid drying of the adhesive thereon after the pre-drying of the flocked yarn. Thus, the flocks on the surface of the dried flocked velvet-looking yarn are
prevented from hardening and crushing or directing in different directions when touched. The purpose of the blowing fan is to remove free and dead flocks through the sieve.
The accumulator (F) is a unit that saves time for yarn back-up without stopping the machine to change the rollers of wrapped yarns at the end of the line. This period and yarn length may vary depending on the characteristics of the accumulators.
The roller butterfly winding unit (G) for flocked velvet-looking yarn is the unit where the flocked yarn is collected after drying processes. This unit includes yarn filling rollers and a butterfly unit. In this unit (G), flock-coated yarns are transferred to yarn filling rollers (H) by the butterfly system.
In the flocked velvet-looking yarn production machine developed with this invention, the yarns (0) to be flocked are first passed through the appropriate parts of all units of the machine with the guide. During this guide-passing process, the following steps are followed;
• The yarns (1) to be flocked are prepared by passing through the yarn entry tension pressure cylinder group (2). Prepared yarns (1) are passed under the yarn entry tension group (3) and yarn centering and guiding cylinder group (4) in the adhesive application unit (B; B1-B2), and they are passed through from the adhesive dispensing cylinder group horizontally (5) or vertically (50· The adhesive dispensing cylinder group is used on the horizontal (Bl) axis for standard production yarns (1-6 Nm), and on the vertical axis (B2) for yarns of a special thickness (1-10 mm in diameter).
• Subsequently, the yarn (1) is passed through the upper flock dosing (20), energized brushed flock chamber (21), static wire (22) and stripping conveyor (23) with a brush over the table, high voltage energized conductive table (24) by static energy loading (Cl) with the conductive table in the flocking unit (C; C1-C2-C3) in flocking, static energy loading (C2) on the adhesive through the copper bar (27) placed in the adhesive in front of the cylinders, feeding the flocks to the adhesive (12) coated yarns (13) from the bottom (C3) in the flocking unit.
• Then, the tension is controlled up to the end of the line with the help of the yarn centering and guiding cylinders (4) that ensure the return of the yarn in the input and output ports of this unit through the flock-coated yarn drying oven.
• The yarns passed through the drying unit (D) are then passed through the fixator unit (E).
• Subsequently, the flock-coated yarn is first passed under the pulling cylinder group (4) in the accumulator unit (F), and the flocked velvet-looking yarn is delivered to the butterfly roller winding unit (G).
• The accumulator unit of the flocked yarn, which is delivered to the butterfly roller winding unit (G), is delivered to the flock-coated yarn rollers winding unit (G) by tension stabilization (F). In this system, flock-coated yarns are transferred to yarn filling rollers (FI).
After the guide-passing process is completed, production can be started on the machine.
The adhesive coated yarn (13) ate flocked at high voltages in the brushed flock chamber (21) and the brushed stripping conveyor (23) on the table and moves towards the drying unit (D). Meanwhile, the excess part of the flocks thrown on the yarn from the upper flock dosing chamber (20) is absorbed and removed from the environment by the flock return chamber (16) and the flock feedback fan (17).
