The following is a description of an embodiment of the "double-sided circular elastic fabric and its manufacturing system" disclosed in the present disclosure by a specific embodiment, and those skilled in the art can understand the advantages and effects of the present invention from the contents disclosed in the present specification. The present invention may be implemented or applied in various other specific embodiments, and various details in the present specification may be made based on different viewpoints and applications, and various modifications and changes may be made without departing from the spirit of the present invention. In addition, the drawings of the present creation are only for the purpose of simple illustration, and are not stated in advance according to the actual size. The following embodiments will further explain the related technical content of the present invention, but the disclosure is not intended to limit the scope of protection of the present invention.

First, please refer to Figures 1 to 5. 1 is a schematic structural view of a double-sided circular elastic fabric provided by one embodiment of the present invention; and FIGS. 2 to 5 are photomicrographs of a double-sided circular elastic fabric provided by one embodiment of the present invention. The double-sided circular elastic fabric provided by one embodiment of the present invention comprises a surface structure 1, a bottom structure 2, and an intermediate structure 3 disposed between the surface structure 1 and the bottom structure 2. Referring to Figures 2 to 5, the surface structure 1 comprises an anti-plain weave 11, the bottom structure 2 comprises a regular weave segment 21, and the intermediate structure 3 comprises interlocking hanging knits for joining the anti-plain weave 11 to the regular weave segments 21. Paragraph 31. In other words, the double-sided circular braided elastic fabric F is formed by the surface layer structure 1, the underlying structure 2, and the intermediate structure 3 having different weave segments (knitted structure).

Specifically, the surface structure 1 and the bottom structure 3 of the double-sided circular elastic fabric F both include a plain weave (also referred to as a plain weave). The plain weave section is formed by continuously connecting the warp and weft yarns in a continuous up-and-down manner. The surface structure 1 and the plain weave segment included in the bottom structure 3 are different in that when the surface layer structure 1 and the bottom layer structure 3 are respectively formed by different yarn feeding units, the yarn is eaten by the single upper needle plate and the empty needle needle of the lower needle tube. The anti-plain weave 11 of the surface structure 1 is produced without the yarn, and the plain weave 21 of the underlying structure 2 is produced by the single lower needle and the upper needle without the yarn.

In addition, for the intermediate structure 3 of the double-sided circular elastic fabric F, which is a pair of plain weave segments formed by the upper needle needle and the lower needle needle by a different yarn feeding unit as described in the preceding paragraph (ie, an anti-plain weave) 11 and the plain weave segments 21) are joined to each other back and forth to form a double-sided circular elastic fabric F. The interlocking hanging knit section 31 included in the intermediate structure 3 is a front-to-back connection of two sets of plain weave sections by a tuck stich weave.

Specifically, the double-sided circular elastic fabric F provided by the present invention is a fabric having a double-threaded interlock, which is a variation of a rib knit. The double-threaded tissue structure differs from the conventional jersey knit in that the front and back sides of the double-sided threaded fabric have the same texture. Such a fabric is thicker in thickness and, because of its very smooth surface, provides an excellent touch and feel to the wearer.

Next, please refer to FIG. 6 and FIG. 7. Figure 6 is a photomicrograph of a double-sided circular elastic fabric provided by one of the embodiments, and Figure 7 is a partial enlarged view of Figure 6. As shown in FIG. 7, the double-sided circular elastic fabric F includes a plurality of yarn loops L. In the present creation, the plurality of yarn loops L each have a diameter of between 0.01 and 0.05 cm.

In the embodiment of the present invention, the anti-plain weave 11 of the surface structure 1 and the plain weave segment 21 of the bottom structure 2 are both woven by the inelastic yarn and the elastic yarn, and the intermediate structure 3 is interlocked. The hanging knit section 31 is woven from an elastic yarn. Specifically, the elastic yarn for weaving the anti-plain weave 11 of the surface structure 1 and the plain weave 21 of the underlying structure 2 and the elastic yarn for the interlocking hanging knit section 31 for weaving the intermediate structure 3 may be Same or different materials.

In other words, in the embodiment of the present invention, the anti-plain weave 11 of the surface structure 1 and the plain weave segment 21 of the underlying structure 2 are both woven by the inelastic yarn and the first elastic yarn, and the middle The interlocking hanging knit section 31 of the structure 3 is woven from a second elastic yarn. The first elastic yarn and the second elastic yarn are formed of the same or different materials.

As stated above, the non-elastic yarn is at least one of nylon (Nylon), polyester fiber, polylactic acid fiber, polytrimethylene terephthalate (PET) fiber, and cellulose fiber. One. The elastic yarn is formed of at least one of Spandex, Lycra, natural rubber, and synthetic rubber. For example, in one of the embodiments of the present invention, nylon is used as the non-elastic yarn, and the used fiber (Lycra) is used as the first elastic yarn and the second elastic yarn. The filament of the inelastic yarn can also be adjusted as needed. For example, in one embodiment of the present invention, a strip of 12 PET fiber (30D/12F) is used to form the non-elastic yarn. . In general, the higher the number of yarns, the better the feel of the finished product.

It is worth noting that in order to provide the double-sided circular elastic fabric F provided by the present invention with excellent elastic recovery rate, in addition to selecting the appropriate fiber materials listed above, it is necessary to precisely control the double-sided circular elastic fabric F. The ratio of the weight between the inner elastic yarn and the inelastic yarn. Specifically, the ratio of the weight of the elastic yarn to the weight of the non-elastic yarn is between 4:6 and 8:2. Further, the sum of the weight of both the first elastic yarn and the second elastic yarn and the weight of the inelastic yarn are between 4:6 and 8:2. In other words, the weight ratio of the inelastic yarn is between 60% and 20%, and the weight ratio of the elastic yarn is between 40% and 80%, and the sum of the two weights is 100%. For example, in one embodiment of the present work, 40% by weight of inelastic yarn and 60% by weight of elastic yarn are used to form a double-sided circular elastic fabric F.

In detail, in the manufacturing process of the double-sided circular elastic fabric F, if the weight ratio of the elastic yarn is increased, the double-sided circular elastic fabric F manufactured therefrom has high elasticity. However, a higher content of the elastic yarn lowers the feel of the product, that is, the material of the non-elastic yarn (for example, PET) has a rubber hand and is less skin-friendly. Therefore, the proportion of the inelastic yarn needs to be precisely regulated, and in accordance with the ratio of the yarn material, the corresponding manufacturing method steps can also be used to produce the double-sided circular elastic fabric F to obtain better product characteristics.

In addition, the Danny number of the inelastic yarn is between 20 and 40 denier, and the Danny number of the elastic yarn (including the first elastic yarn and the second elastic yarn) is between 60 Between 80 Danny. In addition to adjusting the weight ratio of the elastic yarn and the inelastic yarn, the Danny number of the two materials is also related to the feel and elasticity of the finished product. For example, in one embodiment of the present work, a 30 denier inelastic yarn and 70 denier elastic yarns are used to form a double-sided circular elastic fabric F.

In addition, the double-sided circular elastic fabric F provided by the present embodiment has excellent elastic recovery. Specifically, the double-sided circular braided elastic fabric has a warp elastic recovery rate and a latitudinal elastic recovery ratio of more than 95%. By precisely controlling the selection of materials and their proportions, as well as the weaving method in the manufacturing process and the parameters of the dyeing and finishing step, the double-sided circular elastic fabric F having the above elastic recovery ratio can be suitably applied to the intimate clothing product.

The finished product of the double-sided circular elastic fabric F may have a unit weight of between 330 g/yd and 680 g/y. in addition to the elastic recovery rate described above. The width of the double-sided circular elastic fabric F can be between 116 cm and 152 cm. When the double-sided circular elastic fabric F has the above unit weight and/or width, an optimum elastic recovery ratio can be obtained.

The manufacturing system S includes a weaving device 41 and a dyeing and finishing device 42. The weaving device 41 and the dyeing and finishing device 42 are disposed on the same production line. In addition to the weaving device 41 and the dyeing and finishing device 43, the manufacturing system S may additionally include a spinning device (not shown) for providing the yarn material required for the weaving device 41. In other words, fibers of different materials can be made into yarns by a spinning device, and the yarns can be fed into a weaving device to be woven into a cloth.

Specifically, the weaving device 41 includes a double-sided circular knitting machine. A double-sided circular knitting machine is used to woven a yarn material, that is, an elastic yarn and an inelastic yarn, to each other to form a double-sided circular elastic fabric. As described above, the elastic yarn may include the first elastic yarn and the second elastic yarn, and the first elastic yarn and the second elastic yarn may be formed of the same or different materials. The composition and characteristics of the yarn used in the weaving device 41 have been described above in relation to the double-sided circular elastic fabric F. For example, elastic yarn The ratio of the weight to the weight of the inelastic yarn is between 4:6 and 8:2. Other details about the yarn will not be described again.

The double-sided circular knitting machine in this creation can use the structure of the commercial double-sided circular knitting machine, and the structure and operating parameters are improved. In general, the double-sided circular knitting machine may include basic components such as a motor and a conveying mechanism, a yarn feeding mechanism, a yarn storage unit, a yarn feeding unit, a weaving unit, and a winding mechanism. The function of the various substrate device components of the double-sided circular knitting machine is well known to those of ordinary skill in the art and will therefore not be described in detail herein.

During the weaving process, the yarn feeding mechanism drives the yarn removing unit to feed the yarn into the yarn feeding unit, and the yarn feeding unit supplies the yarn at a fixed angle of travel to feed the yarn into the weaving unit. The weaving unit comprises a needle barrel and a knitting needle which is inserted into a groove in the surface of the barrel and controls the knitting process to form a loop by various cams (Cam) in a cam box. In the basic device components of a double-sided circular knitting machine, the creation is specifically adapted to the operating parameters in the yarn feeding unit.

Please refer to Figure 9. FIG. 9 is a schematic structural view of a yarn feeding unit 411 in a manufacturing system of a double-sided circular elastic fabric provided by one embodiment of the present invention. In detail, the double-sided circular knitting machine includes a yarn feeding unit 411 having a yarn feeding rod 4111, a yarn feeding port 4112, and yarn feeding nozzles 4113 and 4114. The yarns Y1, Y2 formed of different materials, for example, the non-elastic yarn and one of the first elastic yarn and the second elastic yarn are passed at an incoming yarn angle θ1 of between 10 and 45 degrees. The yarn feeder 4112 enters the yarn feeding nozzles 4113, 4114 at a yarn feeding angle θ2 of between 15 and 45 degrees.

As shown in FIG. 9, in the present embodiment, the yarn entrance angle θ1 of the yarn inlet port 4112 refers to the angle between the yarn Y1 passing through the yarn inlet port 4112 and the horizontal plane (indicated by the broken line), and the yarn feeding nozzle 4113 The yarn feeding angle θ2 is an angle between the yarn Y1 and the horizontal plane when the yarn Y1 passes through the yarn feeding nozzle 4113. For the yarn Y2, the yarn entry angle θ1 and the yarn feed angle θ2 as described above can also be used. For the yarn Y2, only the yarn feeder 4114 is illustrated in FIG. For example, in the present creation, the yarn Y1 is a polyester fiber. Y2 is an elastic yarn. Any one of the yarns Y1 and Y2 is adjusted, and even the yarn entry angle θ1 and the yarn feed angle θ2 of the both are in the above specific range, and a cloth having excellent characteristics can be obtained. Specifically, when the non-elastic yarn and the elastic yarn having a specific weight ratio are selected to weave the double-sided circular elastic fabric, the yarn entering angle θ1 and the yarn feeding angle θ2 are adjusted to the above-mentioned appropriate range (ie, the yarn entering angle) Θ1 is between 10 and 45 degrees, and the yarn feeding angle θ2 is between 15 and 45), so that the double-sided circular elastic fabric F can be made to achieve both elastic recovery and hand feeling.

In addition to this, during the weaving process, the yarn supplying rod 4111 of the yarn supplying unit 411 can be moved relative to the center (moving direction D) of the double-sided circular knitting machine. The range in which the yarn feeder 4111 moves relative to the center of the double-sided circular knitting machine is between 10 and 50 centimeters (mm). Specifically, the manufacturing system provided by the present invention adjusts the characteristics of the double-sided circular elastic fabric F thus formed by setting the yarn entry angle θ1, the yarn feed angle θ2, and the back-and-forth movement range of the yarn feeding rod 4111. For example, the adjustment of the above parameters can adjust the fabric flatness of the fabric, the size of the loop of the yarn loop, and the elasticity.

Next, please refer to FIG. 8 again, and cooperate with FIG. 10 and FIG. Figure 10 is a schematic view showing the structure of the dyeing and finishing device 42 in the manufacturing system of the double-sided circular elastic fabric provided by one embodiment of the present invention, and Figure 11 is a structure of the dyeing and finishing device 42' used in another embodiment. schematic diagram. Referring first to FIG. 10, the dyeing and finishing apparatus 42 includes a dyeing and finishing line 421 for receiving the double-sided circular elastic fabric T from the weaving device 41. As shown in FIG. 10, the dyeing and finishing device 42 further includes a heat exchanger 422 connected to the dyeing and finishing line 421, a liquid storage tank 423 for storing the dyeing and finishing liquid or the auxiliary agent, and is used for winding double-sided circular knitting elasticity. Winch 424 of fabric T and window 425.

In addition, in the embodiment shown in FIG. 11, the dyeing and finishing device 42' also includes a dyeing and finishing line 421', a heat exchanger 422' connected to the dyeing and finishing line 421', and a storage liquid for dyeing and finishing. The liquid storage tank 423', the winch 424' for winding the double-sided circular elastic fabric T, and the window 425'. Unlike the dyeing and finishing device 42 shown in Fig. 10, the dyeing and finishing device 42' shown in Fig. 11 is a lower-pass dyeing machine.

In the present creation, a high temperature and high pressure dyeing machine is used as the dyeing and finishing device 42. More In essence, the dyeing and finishing device 42 used in this creation belongs to a soft-flow dyeing and finishing machine. This dyeing machine is characterized by a relatively low liquid/fabric ratio (e.g., 10:1) and can achieve higher processing temperatures. In addition, the slow-flow dyeing machine has a high fabric capacity and is not easy to cause a pilling effect of the fabric.

The dyeing and finishing line 421 of the dyeing and finishing device 42 of the present invention is a cylinder dyeing cylinder carrying a dyeing and finishing water flow and a double-sided circular elastic fabric T, a cylinder dyeing cylinder and a plurality of water pressure nozzles (nozzles arranged around the cylinder dyeing cylinder) For example, the nozzles 426' shown in Fig. 11 cooperate with each other. Specifically, in order to convey the double-sided circular elastic fabric T from the double-sided circular knitting machine in the dyeing and finishing line 421, the sprayed liquid is supplied into the cylinder dyeing cylinder through the water pressure nozzle, and turbulence is generated. . This mechanism allows the dye to penetrate the inside of the double-sided circular elastic fabric T and prevent the double-sided circular elastic fabric T from touching the inner wall of the cylinder dyeing cylinder.

In the present embodiment, the cylinder dyeing cylinder has a pipe diameter of between 4 and 10 Torr, and the water pressure of the dyeing and finishing water in the cylinder dyeing cylinder is between 0.5 and 2 bar by the parameter setting of the water pressure nozzle. between. As previously mentioned, when a slow flow dyeing machine is used, the fabric flows in the dyeing water stream to adhere the dyeing material (e.g., dye) included in the dyeing water stream to the fabric. However, if the amount of water in the dyeing water flow and the water pressure are not properly controlled, the fabric may undergo entanglement and greatly affect the characteristics of the product.

One of the aims of the present invention is to obtain a double-sided circular elastic fabric F having excellent elastic recovery. Therefore, in addition to the selection of appropriate yarn materials and the use of appropriate weaving methods, it is possible to further control the diameter of the cylinder dyeing cylinder to a specific range and to control the water pressure of the dyeing and finishing water flow. Specifically, the diameter of the cylinder dyeing cylinder is between 4 and 10 Torr, which is approximately doubled compared to the diameter of the dyeing cylinder of the slow-flow dyeing machine used in the prior art. In this way, the double-sided circular elastic fabric T carried therein can be fully stretched and rolled in the dyeing and finishing water flow to avoid the occurrence of entanglement or entanglement, and affect the elastic recovery rate of the finished product.

In addition, compared to the water pressure used in the prior art, the water pressure will be created at the time of creation. Reduce to about 10 to 50% of the conventional water pressure, that is, control the water pressure between 0.5 and 2 bar. By adopting the above-mentioned cylinder dyeing cylinder diameter and the water pressure range of the dyeing and finishing water flow, it is possible to effectively avoid the entanglement of the fabric when manufacturing a thicker and denser fabric.
