Description

HIGH PILE FABRIC MANUFACTURED FROM TRICOT WARP KNITTING MACHINE AND THEREOF MANUFACTURING METHOD}

The present invention relates to a high pile warp knitted fabric using a tricot warp knitting machine and a method of manufacturing the same, and more particularly, to solve the problem of morphological instability by a method of controlling the organization and run-in of the knitted fabric. The present invention relates to a technique for manufacturing a high pile warp knitted fabric to solve and maximize the flexibility and random direction of the pile.

In general, products with a high pile (products with a file length of 3.2 mm or more) are supplied by a high pile knitting machine together with a yarn and a spinning thread for knitting a pile, and then using a resin such as latex. It is manufactured by fixing, the material of the knitted fabric is used rayon, acrylic, polyester, vinylon, propylene and the like. Such a high pile knitted fabric has a length of 3.2 to 25 mm, which is rich in volume, and has the advantage of being manufactured with various touches, and is mainly used for toy dolls or artificial fur decoration for clothes.

However, the quality of the product is determined in the knitting process, the volume is large due to the sense of volume, the burden of the cost of transportation, and there is a problem that there is a limit in post-processability, as well as the file is easily pulled out by friction. In addition, the daily productivity is very low compared to 300yards / day tricot warp knitting machine.

On the other hand, when the high pile product is knitted with a tricot warp knitting machine, the length of the pile is relatively short (3-10 mm) compared to the high pile product made of the circular knitting machine, and the transportation cost is low, and there is no limit in the post-processing properties, which can produce various effects. In addition, there is an advantage that the pile does not fall out at the time of friction or tension, and the productivity is much higher than that of the high pile product manufactured with a circular knitting machine at 2000yds / day.

Velours knitted with conventional tricot warp knitting techniques have been manufactured predominantly with 3-bar warp knitting machines. Such a manufacturing method is a technique of forming a branching structure of L1 and L2 bars, forming a loop (pile) of L3 bars, and then raising and cutting the loops to form a pile.

However, when manufacturing velors using conventional tricot warp knitting techniques, the back shogging distance of the L3 bars is limited to about 2 to 5 needle pitches, so that the length of the pile is looped. Has been formed relatively short (about 1 ~ 3mm), which is a problem of shape instability caused by the pile yarn floating on the surface if the length of pile is increased, and the timing of the machine caused by the long skip of the guide bar. This is because there have been difficulties such as technical problems such as excessive wear and wear, and raising problems caused by increasing number of yarns to be raised per unit area.

In addition, since most of the fabrics and pile yarns use polyester of general fineness as a yarn, about 2 denier filaments form piles, and 2 denier polyester filaments are piled up in the direction perpendicular to the tissue. Because it has bending stiffness, it stood in a uniform direction with respect to the branch tissue, so it was difficult to expect a good effect because it felt a rough touch.

FIG. 1A is an enlarged view of a surface of a conventional velor 40 times, and FIG. 2A is an enlarged view of a conventional Velor 40 times, using a threshold.

As shown in Figs. 1A and 2A, the surface of a velour knitted by the conventional warp knitting technique has a pile standing stiffly in a uniform direction, the cross section of the raised and cut polyester yarn is rough, and the length of the cut fiber is one You can see it's not fixed. Thus, velors knitted with conventional warp knitting techniques have a slight metallic luster due to the direction of the pile, while having a rough touch due to the non-uniformity of the cut polyester yarn cross section and the rigidity of the yarn itself.

As described above, velors knitted by the conventional warp knitting technology have been limited to a length of 1 to 2 mm, and high pile products having a file length of 3 to 10 mm are already provided by a warp knitting machine manufacturer with a pattern wheel for manufacturing a high pile. Even if it is, there has been a problem that the wear of the machine is increased by an excessive skipping interval.

In addition, the biggest problem when the velor is knitted by the conventional warp knitting technique is that the problem of shape instability due to the long floating of the pile on the surface of the tissue.

The present invention has been made to solve the above problems, the file lengthened through the method of controlling the structure of the velor's paper tissue and the run-in, heat setting temperature, etc. The present invention provides a high pile warp knitted fabric using a tricot warp knitting machine and a method for manufacturing the same, which are stable even after long floating on the surface of the tissue and that the variation of shrinkage rate is not large so that the problem of morphological stability that occurs during high pile manufacturing can be solved. The purpose is.

Another object of the present invention is to make it possible to solve the problem of raising caused by increasing the number of pile yarn passing per unit area by increasing the pile length by adjusting pile yarn and raising conditions.

Still another object of the present invention is to use an ultrafine pile yarn having a low bending stiffness, and to add a post-processing process to give a random orientation to the high pile so as to convert the metallic luster of the existing velour into an elegant luster.

In addition, the present invention to overcome the limitation of the post-processability of high-pile products made of circular knitting machine in addition to the above-mentioned object, but to use a microfiber as a pile, omit the weight loss division process to reduce the process cost while having a differentiated touch microfiber The purpose is to provide a manufacturing technique of high touch, high pile warp knit fabric using.

The present invention configured to achieve the above object is as follows. That is, the high pile warp knitted fabric according to the present invention is a pile warp knitted with tricot warp knitting machine, L1 and L2 forming a paper structure using polyester yarn, and L3 forming a pile has a single yarn fineness of 0.2 to 0.5 denier When using the microfiber yarn to calculate the run-in when knitting tissues with a knitting needle interval of 6 knitting needles or more, under the same density, the run-in of the L3 guide bar is not changed and the run-in of the L1 and L2 guide bar is not changed. After raising enough to control the knitting after knitting so that the shrinkage fluctuations of the knitting is not large.

In the above-described configuration, the fibrous yarn is stiff than the conventional one in order to eliminate the problem of knitting, which causes the fibrillation to cry or become unstable due to the long float of the pile yarn on the surface of the knitted fabric. A reverse half stitch (L1: 23 10, L2: 10 12) is designed to support long-floating pile yarns, and to increase the number of intersections per unit area to secure the pile yarns firmly. It can be used for L1 and L2 local tissues.

If the skipping needle interval of L3 is 6-10 stitches or more when the skipping needle interval is 6-10 stitches, the reverse half-harp side of the reverse direction is used as the local tissue. The reverse half can be designed with geotextiles to stabilize the fabric.

On the other hand, as described above, the method configuration for knitting the high pile warp knitted fabric according to the present invention has a single yarn fineness of 0.2 to 0.5 denier of the polyester yarns of the L1, L2 guide bar forming the paper structure and the L3 guide bar forming the pile Arranging a polyester microfiber of tricot warp knitting machine; Designing the paper tissue to form a high pile having a pile of 3 mm or more with a skipping knitting interval of the L3 guide bar of 6 knitting needles or more, while weaving the fabric by appropriately adjusting the run-in; Refining the knitted fabric under a temperature condition of 90 to 100 ° C; Heat-setting and quenching the refined fabric under a temperature condition of 200-220 ° C. to stabilize the shape of the pile; Heat-setting and quenching the dyeing to stabilize the shape of the pile; Drying the dyed fabric under a temperature condition of 170 to 190 ° C; Printing on the dried fabric after dyeing; Putting the printed fabric into a silicone softener and an antistatic agent and drying the same under a temperature condition of 200 to 220 ° C; Raising the pile of dried fabric after printing; Shearing and polishing the fabric with the pile raised; And causing the pile to lie down or clump in a random direction through astra processing.

At this time, as the pile yarn in the above-described configuration, as the microfibers of 0.5 denier or less, microfibers finely radiated with a single yarn fineness of 0.2 to 0.5 denier during spinning can be used. In addition to the 0.2-0.5 denier microfiber yarns, single-fiber fine-grained fine yarns divided into ultra-fine fibers by dissolving the elutriated component after processing can be used 0.15 denier-grade polyester split yarns and 0.06 denier-class island-in-the-sea microfiber yarns. In the case of use, the process cost is further increased because weight loss processing is required to dissolve the usable component. However, since the fineness of each microfiber is different, the high pile warp knitted fabric which used each yarn as a pile shows each different effect.

On the other hand, the run-in of the L1 and L2 forming the liposomes is sent out more than the run-in by the original calculation, and then sufficiently relaxes the form at the time of dry relaxation and wet relaxation, and high temperature. Heat set at to stabilize the shrinkage so that the variation of shrinkage is not large.

In addition, the underlying tissue is based on reverse half stitch (L1: 10 23, L2: 12 10) rather than the commonly used double denbigh stitch (L1: 10 12, L2: 12 10). By using it as the base tissue is more densely, harder and stiffly knit, even if the pile yarn is long floating, the base tissue can form a stable fabric by holding the pile firmly, there is an advantage to reduce the phenomenon that the pile yarn falls out.

In addition, the direction of movement of the guide bar causes L1, L2, and L3 to move in the same direction (parallel) or only L1 to be a counter.

Hereinafter, a high pile warp knitted fabric using a tricot warp knitting machine and a manufacturing method thereof according to a preferred embodiment of the present invention will be described in detail.

The high pile warp knitted fabric according to the present invention solves the problem of shape stability and raising caused by the length of the pile by changing the organization, run-in, heat setting temperature, raising conditions, etc. To reduce the bending stiffness by using microfiber for pile yarns, to make the piles more flexible, and when long piles exhibit diffuse reflection (many fine convex convexities on the surface of the object that are roughly the same as the wavelength of the light), It is a phenomenon that reflects and scatters in various directions from the surface to give a deep color, soft gloss and soft touch. This knitted high pile warp knit can be used in high-quality toy dolls or clothes with luxurious colors, luster and touch.

When the high pile warp knitted fabric using the tricot warp knitting machine according to the present invention as described above is manufactured using 3-bar, L1 and L2 guide bars form a liposome, and the L3 guide bar is a pile To be formed. At this time, the dough width and final completion width on the warp knitting machine is about 30 to 50% shrinkage, the float of the pile forming yarn of the L3 guide bar (floating, it refers to the floating portion without forming a ring in the knitted fabric) The longer the interval Shrinkage increases and the shape becomes unstable.

Therefore, in order to solve the problems as described above, the present invention was improved by the following method to produce a high pile warp knitted fabric.

First, since the high pile warp knitted fabric according to the present invention has a long file length, the float interval is long, and thus the present invention has developed a knitted tissue design method for solving the problem of morphological stability. In other words, general pile warp knitted fabric consists of 2-bar, 3-bar, 4-bar, and consists of the branch tissue history forming a base branch tissue and the pile yarn forming a pile, and the branch organization plays a role of holding and supporting the pile. do. In the case of 2-bar pile fabrics, L1 usually uses a single denbigh stitch (L1: 10 12) as a paper tissue, and when knitting a file warp knitted fabric with 3-bar or 4-bar, L1, Double denbigh stitch (L1: 10 12, L2: 12 10) has been commonly used as the liposome.

The reason why the above-mentioned single denby stitch or double denby stitch is used as the paper tissue is that the Denby stitch is the simplest structure in the warp knitting tissue. It can hold the skipping yarn relatively firmly, and the pile length of the existing pile warp knitted fabric is 1 ~ 3mm, so that the knitting needle spacing is relatively small, so the single yarn or double denby tissue can be firmly held. Because it was.

However, as the file length of the file warp knitted fabric becomes longer, the probability of the file falling out due to friction increases, and the local organization not only needs to hold the file yarn more firmly so that the file does not fall out, but also the skipping needle interval reaches 6 to 18. Due to the long floating pile yarns, the ground tissues of the ground cry or become unstable, so when designing the ground tissues with existing Denbigh tissues, various problems occur in the cutting and processing.

Therefore, the present invention solves this problem by changing the design method of the branch tissue to hold the pile yarn. That is, the high-pile warp knitted fabric of the present invention is knitted with three guide bars to form a branch tissue using two guide bars L1 and L2, which allows the base tissue to firmly hold the pile yarn, In order to prevent this crying or shape instability, reverse half stitch is designed to support the pile yarn which is stiffer than the existing one.

The reverse half-harp piece used as the paper tissue in the present invention has a smaller elongation and resilience as compared to the double denby piece, a large bending stiffness and a bending history, a large stiffness and a shear history, and a small recovery to compression. The texture of the fabric is larger and stiffer than that of the double denbigen piece (see FIGS. 9 to 20). Therefore, even if the pile yarn is floated for a long time, the paper tissue itself can be more stiff and stable to maintain its shape, so that it is possible to manufacture a high pile warp knitted fabric having a stable shape. In addition, due to the characteristics of the tissue, the reverse half-harvested tissue has a greater number of intersection points between the yarns and yarns than the double denby piece, so it can hold the pile yarn more firmly. There is an advantage that can reduce this falling out.

On the other hand, both the reverse reverse half piece in the reverse direction and the reverse reverse half piece in the reverse direction may be used for the branching structure, and it is advantageous to use the reverse reverse half piece in the opposite direction as the skipping distance of the L3 guide bar increases. The inverse half-harp piece in the coarse direction has less elongation and stretch recovery, greater bending stiffness and bending history, greater stiffness and shear history, and greater recovery in compression compared to the reverse half-half piece in the reverse direction. This is because the stiffness is also small and the fabric is larger and stiffer than the reverse half of the reverse side (see Figs. 9 to 20), so that it can better support a long-floating pile yarn. In addition, after raising, the reverse half-harp pile in the opposite direction is superior to the reverse half-harp side in the reverse direction.

However, when the reverse half-half piece tissue in the same direction is designed as a geotextile, since the L1, L2, and L3 guide bars all move in the same direction and are knitted, the resilience of the biased direction of the knitted piece tissue is bad, and the snare ring There is a risk of snarling. Therefore, it is advantageous for one of the L1, L2, L3 guide bars to move in the reverse direction.

Therefore, when manufacturing warp knitted fabrics of high piles (more than 6 stitches of L3 guide bar skipped), tissues with relatively short piles are designed with the reverse half-harp side of the reverse tissue and the piles longer. If it loses, it is designed to be in reverse half-harp in the same direction so that it can support high pile yarn well.

In the above description, the structure of the high pile warp knitted fabric when the reverse half-harp piece having a pile length of 3 mm is designed as a geotextile is shown in FIG. 6, and the pile lengths are 7 mm and 10 mm, respectively, in the same direction. The organization diagrams of the high pile warp knitted fabric of the reverse half-haven piece with the geotextiles are as shown in FIGS. 7 and 8.

In addition, the physical property comparison of the double denby piece and the reverse half-harp structure in the same direction and the reverse direction is shown in FIGS. 9 to 20.

Second, in the present invention, when the run-in is calculated by calculation, the run-in of the L3 guide bar is not changed under the same density, and the run-in of the L1 and L2 guide bar is adjusted to be sufficiently long so that the loop ( After the loop is loosely formed, the shrinkage rate is reduced to about 20 to 30% by sufficient natural shrinkage during drying and wet relaxation, and the long pile warp knitted fabric is formed by heat setting at a higher temperature (about 200 to 220 ° C) than conventionally. The stabilization of, and raising was raised well.

Third, raising the pile length caused the problem of raising caused by the increased number of pile yarns passing per unit area. In other words, the file knitting of the short file of the existing file is about 2 to 5 stitches apart from the interval between 2 and 5 stitches, but when the number of file yarns passing between the stitches is about 2 to 5, the number of skipped stitches reaches 6 to 18, Since the number of pile yarns passing between one hand becomes 6-18, the number of pile yarns passing per unit area increases, and the piles are not broken when brushed under the existing raising conditions. Therefore, when raising, the number of steps, weight, tension, etc. of the brush was adjusted, and the conditions of raising were adjusted to obtain a good quality pile without damaging the tissue by appropriately increasing the number of linkages.

Fourth, the use of microfibers that radiate less than 0.5 denier of single yarn fineness during manufacture, rather than the general yarn of about 2 deniers used as pile yarns, reduces tensile strength and weakens resistance to raising, raising can be done more easily. have.

Fifth, the use of microfibers in pile yarns lowers the bending stiffness so that the pile yarns do not stand vertically with respect to the pile yarn structure, giving a soft, tactile feel, and adding a post-processing process to impart random orientation to the high piles. Velor's metallic luster was converted into an elegant luster to produce a high touch, high pile warp knitted fabric with a tricot warp knitting machine.

Looking at the manufacturing method of the high pile warp knitted fabric using a tricot warp knitting machine according to the present invention. First, the yarns are arranged on the L1 and L2 forming the branch tissue and the L3 guide bar forming the pile. At this time, polyester yarns are fixed to L1 and L2 guide bars forming a paper structure, and polyester microfibers having 0.2 to 0.5 deniers of single yarn fineness are also fixed to L3 guide bars forming piles.

On the other hand, the run-in of the L1 and L2 guide bar is calculated to be longer than the calculated run-in, and the run-in of the L3 guide bar forming the pile is calculated as the calculation method. This allows the file to be firmly fixed while preventing the shrinkage variation from becoming too large.

As described above, when the yarn is squeezed to the L1, L2 and L3 guide bars that form the paper structure, the single yarn fineness squeezed to the L3 guide bar is chemically divided in the machining process instead of 0.2 to 0.5 denier microfiber. Among the constituent polymers, a polyester forming yarn and a single yarn fineness composed of a fiber forming component for dissolving a soluble component which is a modified polymer, and a soluble component can be used. In this case, in the case of using the divided yarn and the island-in-the-sea ultrafine yarn for dissolving the soluble component, a process of dissolving the soluble component which is a modified polymer among the yarn constituent polymers through chemical division is required.

After arranging the yarn on the tricot warp knitting machine, the fabric is designed to form a high pile having a skipping interval of 6 knitting needles or more, and the fabric is cut by adjusting an appropriate run-in. At this time, the knitted fabric is relaxed and dried at a predetermined temperature.

Drying and loosening the fabric after crushing is refined under the temperature condition of 90 ~ 100 ℃, and the refining of the fabric is a machine used for padding, padding, and dyeing and other processing solutions in the dyeing process. Or a machine used to uniformly squeeze the dispersion from the fabric. Therefore, the fabric is wet and relaxed during the refining process to shrink to a sufficiently stable state.

The refined fabric stabilizes the shape of the pile through a preset. At this time, the temperature is 200-220 ° C., higher than the existing temperature, and heat-set and quenched. By heat-setting and quenching at such high temperatures, the warp knit is further stabilized.

After stabilizing the shape of the pile by heat setting and quenching through a preset, dyeing the fabric, considering that the dyed fabric is microfiber, dried under the temperature condition of 170 ~ 190 ℃, and printing through dyed fabric Dye

The printed fabric is dried under high temperature conditions of 200 to 220 ° C by adding a silicone softener and an antistatic agent, and then piles the pile of the fabric. In this way, the brushing is not performed after presetting, but after dyeing, brushing prevents remnants from being caught on the screen during printing.

Shearing and polishing fabrics piled with piles, and then using astra processing, the high piles can lie or bundle freely in each direction, resulting in diffuse reflection of light, resulting in deeper colors and softer luster. Have it.

When the high-pile warp knitted fabric is knitted through the above-described process, it is possible to manufacture a high touch fabric in which the pile does not fall out because the microstructure is formed of a general polyester firmly supporting the microfiber.

Another method of manufacturing the high pile warp knitted fabric using the tricot warp knitting machine according to the present invention is the same process, but after stabilizing the shape of the pile by heat-setting and quenching through a preset, the dyed fabric is In consideration of being an ultrafine yarn, after drying under a temperature of 170 to 190 ° C., a high touch fabric can be manufactured by raising piles.

Another method of manufacturing a high pile warp knitted fabric using a tricot warp knitting machine according to the present invention is the same process, but after heat-setting and quenching through a preset to stabilize the shape of the pile to dye the fabric, the dyed fabric is It is dried under the temperature condition of 170 ~ 190 ℃ in consideration of microfiber yarn, and after raising pile, astra processing makes high piles freely lie down or bundle in each direction to diffuse light diffusely to deepen color and It is also possible to produce a high touch fabric by having a soft luster.

In addition to the method described above, the above process is the same, but after stabilizing the shape of the pile by heat setting and quenching through a preset, the fabric is dyed, and considering that the dyed fabric is a microfiber under a temperature condition of 170 to 190 ° C It is also possible to manufacture a high touch fabric by drying, dyeing, and then dyeing the shape on the dried fabric after printing.

On the other hand, as in the polyester split yarns and split yarns composed of fiber forming components and soluble release components, single yarns for dissolving the soluble components, which are modified polymers among the yarn-forming polymers, are chemically divided in the dyeing processing process. In the case of using an island-in-the-sea type ultrafine yarn, the shape of the pile is stabilized through a preset, and the weight loss process is performed to form the polyester divided yarn of the L3 guide bar into an ultrafine fiber. In other words, the soluble component of the polyester divided yarn is eluted through the weight reduction process to form the pile yarn of the L3 guide bar into an ultrafine fiber shape of 0.15 denier or less. In this process, the pile formed of ultra-fine yarn is significantly reduced in bending stiffness than conventional pile yarns, and thus has a much more flexible and soft touch.

The above-described polyester split yarn (PCP) has a special cross-sectional shape (8 split type, orange ball type) composed of a general polyester polymer and a modified polyester polymer having high solubility in alkali (Bi-Component, 異狀). Iv) After weaving as a filament yarn, one of the two polymers (Easy soulble PET Alkali) constituting the yarn during the weight reduction process is chemically dissolved with NaOH to remove the residual polymer (Regular PET) by ultra-fine 0.15 denier It is a fiber manufactured in fibrous form. During the weight loss process, the fiber is divided into eight fibers, resulting in an excellent microtextured surface texture.

Meanwhile, an island-in-the-sea microfiber instead of polyester split yarn may be used for the L3 guide bar forming the pile. This island-in-the-sea microfiber (Sea & Island type conjugate fiber, SiF) has a single-fiber fineness of 0.06 denier (0.2μ). It is a yarn with 36 islands. The island-in-the-sea microfiber yarn is a polymer inter-arrangement filament yarn using the same usable polymer as the polyester split yarn, and is a modified polymer of yarn-forming polymer (Sea part) through chemical splitting (reduction) in the dyeing process immediately after weaving. It is a material that dissolves and expresses only 0.06 denier residual polymer (Regular PET Polymer; island part) part to give an excellent surface texture. Such island-in-the-sea microfiber yarns have been developed for use in artificial suede, jackets, coats, and high-end fashion bags, which exhibit a unique high quality, fine touch, and elegant gloss by arranging fine crimps, wools, and loops on the fabric surface. In order to express the suede feeling, surface processing such as buffing, brushing, etc., enables product development such as diversification of use and high value added.

As described above, the reason for the weight loss processing before dyeing is to prevent the color change caused by the weight loss processing after dyeing, and to control the weight loss rate (about 20-25%), not only the elution component is eluted. The oligomer of the general polyester itself is also to be eluted to improve the overall gloss and to be flexible.

For example, if the target reduction rate is 24%, the mixing ratio of the fabric is L1 18%, L2 18%, L3 64%. -0.3) = 44.8. Therefore, the total is 44.8 + 18 + 18 = 80.8, and the dissolution is 100-80.8 = 19.2, so only 19.2% should be reduced, and the target reduction rate is about 20-25%, so that 1-6% is further reduced. Weight loss to increase gloss and flexibility.

Next, a high pile warp knitted fabric using a tricot warp knitting machine according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1b is an example of the velour according to the present invention is a surface enlarged view showing a 40 times magnification of the surface of the velour knitted by using a polyester microfiber of 0.2 to 0.5 denier as the pile yarn without the need for weight loss division, Figure 2b is Threshold As an example of the velour according to the present invention, a single yarn fineness that does not require weight division is an enlarged view showing the surface contour of the velour, which is formed by using a polyester microfiber of 0.2 to 0.5 denier as a pile yarn, 40 times.

The high pile warp knitted fabric using the tricot warp knitting machine according to the present invention uses L1 and L2 to form a paper tissue, and L3 to form a pile uses polyester microfibers having a single yarn fineness of 0.2 to 0.5 denier. The knitting needles are knitted by knitting more than 6 knitting needles, and then brushed and knitted. The length of the pile yarn is longer and more flexible than that of the warp knitted fabrics of FIGS. 1A and 2A, which are conventionally knitted as shown in FIGS. 1B and 2B. It can lie in a random direction, and light causes diffuse reflections on the surface of the pile, resulting in deep colors and soft luster.

The high pile warp knitted fabric according to the present invention, as shown in Figures 3 to 8, L1 (A) and L2 (B) to form a paper texture to the general polyester yarn, L3 to form a spinning process The single microfiber yarns are prepared from 0.2 to 0.5 denier, and the yarns divided into microfiber yarns during weight loss processing are cut into pieces.

Example 1

First, ordinary polyester yarns for filing and microfibers for piles are fixed to L1, L2 and L3 guide bars. At this time, the pile yarn uses a polyester microfiber yarn manufactured in a single yarn fineness of 0.2 to 0.5 denier in the spinning process, which is a production stage of the yarn.

On the other hand, after cutting the yarn, the dough is adjusted by adjusting the tissue and the run-in so that the length of the file is longer. In this embodiment, the skipping interval of the knitting needles was changed from the conventional 2 to 5 knitting needles, and a reverse inverse half-harp tissue was used as the supporting tissue to support this. The length of the pile is 3 mm, as in the organization chart of FIG.

After refining the dough, the initial heat setting (preset) and quenching, then dyeing, the preparation is added to dry setting (dry setting).

Dyeing the shape on the fabric through printing, and after the printed fabric is dried under a temperature condition of 200 ~ 220 ℃ by adding a silicone softener and an antistatic agent, and raising the pile of the fabric.

After raising the pile, an intermediate inspection is performed, followed by shearing and polishing. By astra processing the fabric after shearing and polishing, the flexible pile lays in a random direction, allowing the surface of the pile to diffusely reflect light, resulting in deep color and subtle gloss.

After the astra processing, the final final setting is carried out again. At this time, the heat setting temperature is slightly lowered and the speed of the passing cloth is increased.

A photograph of a 40 times magnification of the high pile warp knitted fabric according to the present invention completed by the above process is shown in FIGS. 1B and 2B. It can be seen that the file of the high pile warp knitted fabric according to the present invention exhibits a soft and soft feeling when compared with the photographs of FIGS. 1A and 2A which are conventional velor photographs.

Example 2

The rest of the process conditions are the same as in Example 1, but the length of the pile can be made longer by increasing the skipping interval of the L3 guide bar to 12-19 stitches. If the skip interval is increased to 12 stitches, the length of the file is 5 mm. If the skip interval is increased to 13 stitches, the length of the file is 7 mm. do. If the length of the pile is increased in this way, it is possible to design the branch structure in the reverse half-harf side in the same direction. The organization chart of a tissue having a length of 7 mm and a skipping interval of 13 knitting needles after finishing the knitting process of the present invention is shown in FIG. 7. The organization chart of a file length of 10 mm and a skipping interval of 16 knitting needles is shown in FIG. 8.

Example 3

The rest of the process is the same as in Examples 1 and 2, except that the microfiber used as the pile yarn in L3 is not a polyester microfiber having a single yarn fineness of 0.2 to 0.5 denier, an island-in-the-sea microfiber, a polyester / nylon composite split yarn or a island-in-sea type that is not a polyester microfiber Microfiber may also be used. As such, when the microfiber used as a pile yarn for L3 is used as an island-in-the-sea microfiber which is not a polyester microfiber having a single yarn fineness of 0.2 to 0.5 denier, a polyester / nylon composite split yarn or an island-in-the-sea microfiber which is not a polyester microfiber, a weight reduction process is required. The cross section of the pile yarn after the soluble component is eluted by the weight loss processing is separated by using a microfiber of a separation type multi-layer type. You can also use microfibers that are flat or polygonal. As the fineness or cross-sectional shape of the filament forming the file is changed, the bending stiffness of each file can be affected, and thus a different effect can be expected.

Example 4

The rest of the process is the same as in Examples 1, 2 and 3, but the weight loss rate is adjusted by adjusting the concentration, temperature, time, etc. of caustic soda during weight loss processing. The differentiation of the processing conditions can change the surface appearance and properties of the finished product.

The high pile warp knitted fabric using the tricot warp knitting machine according to the present invention configured as described above uses a general polyester yarn for the L1 and L2 guide bars forming a paper structure, and the production stage of the yarn for the L3 guide bar forming a pile. In the spinning process, a polyester microfiber manufactured from a single yarn fineness of 0.2 to 0.5 denier is used. The skipping needle spacing of the L3 guide bar shall be 6 needles or more, and the underlying base tissue shall be knitted after being reversed reverse or half reverse. The longer the pile yarn is, the more stable it is to organize the reverse half-harf piece in the same direction into the geotextile.

At this time, as the pile yarn in the above configuration, single yarn fineness in the spinning process, which is the production stage of the yarn, is composed of a fiber-forming component and a fugitive component instead of a polyester microfiber manufactured in a 0.2 to 0.5 denier class. 0.06 to 0.15 denier-class polyester split yarn and single yarn fineness A 0.06 denier-class ultrafine yarn may also be a island-in-the-sea fine microfiber having 36 islands. In the case of microfibers divided into polyester split yarns and island-in-the-sea microfibers, in the process of dividing, microfibers are formed by diluting the elution component of polyester split yarns through weight loss processing to form pile yarns of ultra-fine fibers of 0.15 denier or less. After brushing.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the technical idea of the present invention.

As described above, in the present invention, a general polyester yarn is used for the L1 and L2 guide bars for forming a paper structure, and the single yarn fineness is also produced in a 0.2 to 0.5 denier class in the spinning process, which is a production step of the yarn, for the L3 guide bar for forming a pile. The high pile warp knitted fabrics which maximize the length, flexibility, and direction of the pile can be obtained by knitting the high pile warp knitted fabric by knitting the knitting needle interval to 6 or more using a microfiber yarn.

That is, the velour of the present invention is not only flexible in comparison with the conventional velour, but also thin and long, soft to the touch, deep in color, soft on the surface, and excellent in drape and flexibility of the finished fabric itself.

In addition, the present invention is to reduce the bending stiffness using the yarn in order to maximize the flexibility and random direction of the pile to improve the feel, not fine-grained through the post-processing, such as weight loss processing, three-sum in the spinning process The cost of the process can be reduced by using the yarn that has been drawn.
