Description

Technical Field

[0001] The invention relates to the technical field of knitted garments, in particular to a fully formed fabric knitted by a four-needle bed flat knitting machine and a knitting method thereof. Background Art

[0002] With people's pursuit of individuality and the great improvement of aesthetic ability, the design of knitted garments has become more and more diversified, especially the development of knitted garments for special application scenarios and application needs has received great attention. As a product of the upgrade of knitting equipment, fully-formed knitted garments have developed rapidly and gradually occupied the clothing, accessories and home improvement markets. Fully-formed garments are mainly knitted using four-needle-bed computerized flat knitting machines, and the one-piece forming of knitted garments is achieved by transferring and turning the coils. At present, fully-formed technology is still in the early stages of development. Limited by the weaving process, the development of fully-formed products is still mainly based on basic tissue structure products, and the patterns are relatively single, making it difficult to achieve fully-formed weaving of hollow patterns or elastic fabrics. Therefore, it is necessary to develop a fully-formed jump knitted fabric woven by a four-needle-bed flat knitting machine and a weaving method thereof. Summary of the invention

[0003] In order to overcome the above-mentioned shortcomings, the object of the present invention is to provide a fully-formed fabric woven by a four-needle-bed flat knitting machine and a knitting method thereof, which can realize the fully-formed knitting of hollow patterns and elastic fabrics.

[0004] In order to achieve the above purpose, one of the technical solutions adopted by the present invention is: a weaving method for a fully-formed fabric woven by a four-needle-bed flat knitting machine, the fully-formed fabric comprising at least one basic structure area and at least one skipped stitch structure area woven into one piece; in the skipped stitch structure area, the main yarn and the auxiliary yarn are woven simultaneously through two yarn mouths, wherein the main yarn is woven into a loop, and the auxiliary yarn is placed after the main yarn is looped in the form of a floating thread, and the main yarn can be exposed on the front side of the skipped stitch structure area.

[0005] The beneficial effects of the knitting method of the present invention are: In the skip stitch area, two yarn mouths are used to knit the main yarn and auxiliary yarn in different ways (looping or floating line) at the same time, so that the skip stitch area presents a double-sided effect, which is conducive to realizing the hollow pattern (lace structure) and the pleated effect of elastic fabric.

[0006] For lace structures, the knitting method of the present invention can weave the lace pattern and the base fabric in the skipped stitch area at one time, which greatly improves the knitting efficiency, reduces the production cost, enriches the knitting process of the lace pattern, and thus realizes the knitting of fully formed lace patterns; for elastic fabrics, the knitting method of the present invention can use the different elasticities of the main yarn and the auxiliary yarn in the skipped stitch area to form a concave and convex pleated effect on the fabric surface.

[0007] The use of one-piece weaving molding can integrate the basic tissue area and the skipped stitch tissue area into the fabric in a seamless manner, ensuring the integrity of the fabric, greatly shortening the weaving time, and reducing production costs. At the same time, the setting of the skipped stitch tissue area enhances the structural enrichment of the fully formed fabric, thereby improving the wearing comfort of the clothing and the aesthetics of the clothing. Furthermore, the two yarn mouths are respectively a main yarn mouth and an auxiliary yarn mouth, and the main yarn mouth is set to be lower than the auxiliary yarn mouth. The main yarn mouth is used to feed the main yarn, and the auxiliary yarn mouth is used to feed the auxiliary yarn. The main yarn mouth is set to be lower than the auxiliary yarn mouth, so that the inlay angle of the main yarn is smaller and the inlay height is higher during weaving, thereby solving the inlay problem of the elastic yarn. Specifically, the main yarn is knitted from the front lower needle bed of the four-needle bed flat knitting machine, and the auxiliary yarn is knitted from the rear lower needle bed of the four-needle bed flat knitting machine. The main yarn and the auxiliary yarn are knitted separately on the front lower needle bed and the rear lower needle bed, and the two yarn mouths can perform different knitting actions by feeding, thereby forming different pattern structures on the fabric surface, forming a double-sided effect.

[0008] Further, in the basic tissue area, at least one of the main yarn and the auxiliary yarn is knitted in a loop to form a full-stitch single-sided structure. In the basic tissue area, only one yarn (main yarn or auxiliary yarn) can be used for knitting according to the pattern requirements, and the other yarn (auxiliary yarn or main yarn) exits the machine and does not participate in knitting. Alternatively, the two yarns can be knitted together in the same knitting action to finally form a full-stitch single-sided structure. Furthermore, the skipped stitch tissue area forms a spindle-shaped lace structure, the main yarn is made of at least one of transparent yarn and fine denier yarn, and the auxiliary yarn is made of at least one of natural fiber, regenerated fiber, and chemical fiber.

[0009] When knitting, the number of knitting needles in the skipped stitch tissue area is not limited and can be adjusted according to the pattern design, and the skipped stitch tissue area can be used locally multiple times to avoid the need for complex shaking, turning needles, shifting circles and other actions to form lace patterns in the prior art. Furthermore, the main yarn material includes at least one of polyurethane, polyester fiber, nylon, and silk. Furthermore, the skipped stitch region forms a surface convex-concave relief structure, and the shrinkage rate of the main yarn is less than that of the auxiliary yarn. Due to the different shrinkage rates of the main yarn and the auxiliary yarn, obvious bulges can be formed in the skipped stitch region.

[0010] Specifically, the main yarn is made of at least one of natural fiber, regenerated fiber, and chemical fiber, and the auxiliary yarn is made of at least one of elastic coated yarn, bare spandex, and polybutylene terephthalate.

[0011] Furthermore, one of the base tissue regions and one of the skipped stitch tissue regions form a knitting loop. The second technical solution adopted by the present invention is: a fully-shaped fabric woven by a four-needle-bed flat knitting machine, which is made by using any of the above-mentioned fully-shaped fabric woven by a four-needle-bed flat knitting machine.

[0012] The beneficial effects of the fully formed fabric of the present invention are: The fully formed fabric made by the weaving method of the present invention broadens the pattern design of the fully formed fabric, and realizes the all-season coverage of the fully formed clothing products, which greatly improves the aesthetics, functionality and comfort of the fully formed clothing. When the weaving method of the present invention is adopted, the lace fabric can be efficiently woven without complex processes such as post-processing, and the weaving of the fully formed lace clothing can be completed without cutting and sewing, enriching the design style of the fully formed clothing; at the same time, the problem of turning the yarn when weaving the bare ammonia elastic yarn can be solved, and the bare ammonia elastic yarn can be smoothly woven on the fully formed equipment such as the four-needle bed flat knitting machine without the need for coating and other composite processes, which effectively solves the limitation of the elasticity of the material of the fully formed clothing, especially for the design and development of high-elastic clothing, which has good application value and market value.

DETAILED DESCRIPTION The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0017] In addition, the reference to "embodiments" in the present invention means that the specific features, structures, or characteristics described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0018] The fully formed fabric knitted by a four-needle bed flat knitting machine of the present invention comprises at least one integrally formed basic structure area and at least one skipped stitch structure area. In the skipped stitch structure area, the main yarn and the auxiliary yarn are knitted simultaneously through two yarn mouths, wherein the main yarn is knitted into a loop, and the auxiliary yarn is placed after the main yarn is looped in the form of a floating yarn, so that the main yarn can be exposed on the front side of the skipped stitch structure area, and the auxiliary yarn can be exposed on the back side of the skipped stitch structure area.

[0019] In the skip stitch area, two yarn mouths are used to simultaneously perform different weaving methods (looping or floating) on ​​the main yarn and the auxiliary yarn, so that the skip stitch area presents a double-sided effect, which is conducive to realizing the hollow pattern (lace structure) and the wrinkle effect of the elastic fabric. For the lace structure, the weaving method of the present invention can weave the lace pattern and the base fabric at one time in the skip stitch area, which greatly improves the weaving efficiency, reduces the production cost, enriches the weaving process of the lace pattern, and realizes the weaving of the fully formed lace pattern; for the elastic fabric, the weaving method of the present invention can use the different elasticity of the main yarn and the auxiliary yarn in the skip stitch area to form a concave-convex wrinkle effect on the fabric surface.

[0020] In addition, the present invention adopts one-piece weaving molding to integrate the basic tissue area and the skipped stitch tissue area on the fabric in a seamless manner, ensuring the integrity of the fabric, greatly shortening the weaving time, and reducing production costs. At the same time, the structure of the fully formed fabric is enhanced through the setting of the skipped stitch tissue area, which improves the wearing comfort of the clothing and the aesthetics of the clothing. It should be noted that the skipped stitch structure is knitted by skipping stitches, and the needles can be selected and knitted independently during knitting. At the same time, the two yarn mouths are selected for action, and the yarn of one yarn mouth is knitted, and the yarn of the other yarn mouth exists in the form of floating yarn. The fully formed fabric in the prior art usually adopts the method of spacer knitting, and can only knit the yarn of one yarn mouth or not produce needles.

[0021] In the basic weave area, according to the actual pattern requirements, the two yarn feeders can move at the same time and weave together to form a full-needle single-sided structure (such as a single-sided plain weave structure) with the same knitting action (such as loop knitting). It is also possible for only one yarn feeder to move to form a full-needle single-sided structure with loop knitting, while the other yarn feeder does not participate in knitting. In the skip stitch weave area, the two yarn feeders need to move at the same time, and one yarn feeder performs loop knitting, while the other yarn feeder allows the yarn to exist in the form of floating yarn, so as to form a double-sided effect in the skip stitch weave area.

[0022] For the convenience of description, the two yarn mouths are called the main yarn mouth and the auxiliary yarn mouth. The main yarn mouth is used to feed the main yarn, and the auxiliary yarn mouth is used to feed the auxiliary yarn. The main yarn mouth is set on the front lower needle bed of the four-needle bed flat knitting machine, and the auxiliary yarn mouth is set on the rear lower needle bed of the four-needle bed flat knitting machine. When setting, the height of the main yarn mouth should be lower than that of the auxiliary yarn mouth, so that the inlay angle of the main yarn is smaller and the inlay height is higher, thereby avoiding the inlay problem of elastic yarns such as spandex.

[0023] In some embodiments, for the lace structure, the main yarn is at least one of transparent yarn and fine denier yarn, and the main yarn material includes at least one of polyurethane, polyester fiber, nylon, and silk. The auxiliary yarn is at least one of natural fiber, regenerated fiber, and chemical fiber.

[0024] When weaving a lace structure, the skipped stitch area can be used locally multiple times, and the number of weaving stitches is not limited and can be adjusted according to the pattern design. The method of this embodiment can achieve fully formed weaving of the lace structure, avoiding the need for complex shaking, turning needles, and shifting circles in the prior art to form a lace structure. In some embodiments, for elastic fabrics, in the skipped stitch area, the shrinkage of the main yarn is less than the shrinkage of the auxiliary yarn, so that the skipped stitch area forms a relief structure with a concave-convex surface. The relief structure is formed by the knitting method of the skipped stitches and the different shrinkage of the main yarn and the auxiliary yarn. Exemplarily, the main yarn is at least one of natural fiber, regenerated fiber, and chemical fiber, and the auxiliary yarn is at least one of elastic coated yarn, bare spandex, and polybutylene terephthalate.

[0025] The four-needle bed flat knitting machine knitting involved in the specific embodiment of the present invention refers to the pattern knitting of fully formed fabrics completed by using a four-needle bed fully automatic computerized flat knitting machine, and lace fabrics and relief fabrics with skipped stitch areas are formed according to different material configurations, structural designs, etc. The following embodiments are described in detail according to the knitting methods of two different fabric styles.

[0026] Example 1: Lace fabric After completing the knitting of the starting part on the four-needle-bar flat knitting machine, full-needle plain weave is used on the front lower needle bed and the rear lower needle bed of the four-needle-bar flat knitting machine to form the basic structure area. Then, according to the needs of the pattern design, the skipped stitch knitting process is performed to form the skipped stitch structure area. The skipped stitch structure area is a hollow, spindle-shaped lace structure.

[0027] For example, Figure 1 As shown, in the first row of knitting, the rear lower needle bed first uses the main yarn of the main yarn mouth 1 and the auxiliary yarn of the auxiliary yarn mouth 2 to form a loop for full needle knitting, and then the two middle needles are knitted with skipped stitches, and the remaining needles are still knitted with full needles. The skipped stitch part allows the main yarn mouth 1 and the auxiliary yarn mouth 2 to enter at the same time, and the height of the main yarn mouth is set lower than the height of the auxiliary yarn mouth. The two middle needles are only knitted by the main yarn mouth 1 to form a loop, and the auxiliary yarn of the auxiliary yarn mouth 2 is placed in the form of floating thread after the main yarn is looped, and the main yarn part is exposed on the front side of the fabric. After the rear lower needle bed is knitted, the front lower needle bed is knitted, and full needle knitting is still used first.

[0028] In practical application, skipped stitch knitting can be used locally according to the pattern design, and the number of knitting needles is not limited. Skipped stitch knitting can be used locally multiple times. When this knitting method is used to knit fully formed lace fabrics, the local use of skipped stitch knitting does not require complicated shaking, needle turning, circle transfer and other actions. The lace pattern and base fabric can be knitted at one time, which greatly improves the knitting efficiency, reduces the production cost, enriches the knitting process of the lace pattern, and realizes the knitting of the fully formed lace pattern.

[0029] In some embodiments, the main yarn is generally one of transparent yarn and fine denier yarn, and the material includes at least one of polyurethane, polyester fiber, thermoplastic polyurethane, nylon, and silk. The auxiliary yarn is generally at least one of natural fiber, regenerated fiber, chemical fiber, etc.

[0030] Example 2: Embossed fabric When elastic yarn is used to weave a fully formed relief fabric, the different elastic shrinkage rates of the main yarn and the auxiliary yarn are used to form a shrinkage effect in the skipped stitch area. The height of the main yarn mouth 1 is set lower than that of the auxiliary yarn mouth 2. The main yarn is made of at least one of natural fiber, regenerated fiber, and chemical fiber, and the auxiliary yarn is made of at least one of elastic coated yarn, bare spandex, polybutylene terephthalate (PBT), and elastic yarn, and the shrinkage rate of the main yarn is smaller than that of the auxiliary yarn.

[0031] Because the surface of the embossed fabric is partially raised, a concave-convex surface is formed, which has an embossed effect. Figure 2 As shown, when knitting, the full-stitch single-sided structure is used as the basic organization. First, all the needles are removed from the front lower needle bed, and referring to the pattern design, 8 stitches are used as a cycle. The main yarn on the main yarn mouth 1 of the two needles on the left and the auxiliary yarn on the auxiliary yarn mouth 2 are knitted together in a loop for full stitch knitting. The remaining six stitches are knitted in a loop by the main yarn mouth 1, and the auxiliary yarn of the auxiliary yarn mouth 2 is a floating yarn. Due to the different shrinkage rates of the main yarn and the auxiliary yarn, an obvious bulge is formed in the skipped stitch organization area. It should be noted that the size of the skipped stitch organization area is only related to the pattern design and the width of the equipment.

[0032] The fully formed fabric knitted with skipped stitches of the present invention is knitted on a four-needle bed flat knitting machine. The knitting of the skipped stitch tissue area can be knitted on the front lower needle bed and the rear lower needle bed respectively. The main yarn and the auxiliary yarn are fed through the main yarn mouth and the auxiliary yarn mouth respectively to perform different knitting actions, thereby forming different pattern structures on the surface of the fabric. The skipped stitch knitting method of the present invention does not require subsequent needle turning, circle transfer or sewing, pasting and other processes to achieve a fully formed pattern fabric. It not only has a simple process and a short production cycle, but also can save a lot of manpower, material resources and production costs. There is no limit on the application of materials. It only needs to match the thickness of the yarn with the needle number of the equipment to successfully complete the knitting, which greatly broadens the application season and application scenarios of the fully formed fabric, especially for the application of summer fully formed clothing, high-elastic sportswear, functional clothing and other fields. It has good application value and market prospects.

[0033] The above implementation modes are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
