Description

Technical Field

[0001] The invention relates to the technical field of knitted clothing, in particular to an air layer structure and process for knitted garments. Background Art

[0002] Knitwear holds a pivotal position in the textile industry. Driven by global technological innovation, it continues to experience rapid growth. The industry's structure has been gradually adjusted, improved, upgraded, and optimized, resulting in an increasingly seamless integration of clothing technology, craftsmanship, and modern art. The level of automation in the current machinery industry is also steadily increasing, with a more comprehensive range of computerized flat knitting machines. The knitting industry chain is becoming increasingly complete, with a growing variety of fabric weaves that can be automatically produced by knitting systems, and the resulting effects in knitted garment design are becoming increasingly diverse. For knitwear designers, while the increasing difficulty of mastering craftsmanship undoubtedly presents unlimited possibilities for modern knitwear design and development. With the continuous development of the market, companies are increasingly realizing that innovative clothing design and development are crucial for enhancing product competitiveness, given the rising aesthetic standards of the public. To further support the healthy and sustainable development of the textile market, it is imperative to strengthen research into innovative products that are distinctively differentiated, innovative, and culturally valuable. Designers should continuously explore new design ideas to create new knitwear that better meets market demand.

[0003] Weave design is a crucial component in the innovative development of knitted products. Due to its unique knitting technology, air-weave can be effectively combined with other weaves to create a rich and varied texture for garments. Currently, the structure of air-weave weave is relatively simple. Summary of the Invention

[0004] The purpose of the present invention is to provide an air layer structure and process for knitted garments to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: an air layer structure of a knitted garment, characterized in that the air layer structure of the knitted garment has: Air layer spot knitting structure, air layer turn stitch structure, air layer purl stitch structure, air layer draw stitch structure, air layer inlay yarn structure, air layer terry structure, air layer floating yarn structure, air layer mesh structure, air layer spaced stitch structure, air layer and multiple structure structures combined with at least one of the above structures.

[0006] Preferably, the local protrusions designed on the basis of the air layer jacquard are obtained by adding a local knitting process to the floating pattern part, and the number of knitting rows in some areas of the upper needle plate exceeds that of the lower needle plate. After the normal washing step, a protruding texture is formed in some areas, and a concave texture is formed in the normal knitting area.

[0007] Preferably, the air layer turning needle structure is knitted in such a way that the working needle plates on both sides of the fabric are different. When the front plate is working, the corresponding rear needle plate is not working, thereby weaving an air layer jacquard fabric with two separated sides. In order to make the jacquard fabric more three-dimensional, when the turning needle is combined, the upper needle plate performs the turning needle action according to the pattern design. The turning needle marks can be seen on the back of the fabric piece. The thickness of the turning needle weaving position will be thinner, and there will be a three-dimensional texture.

[0008] Preferably, the air layer purl stitch structure is designed based on the air layer jacquard basic pattern module, and purl stitch is added to make the fabric surface have concave-convex excitation changes and color changes.

[0009] Preferably, the air layer needle-pulling structure is knitted on the basis of weft plain needles with needle-pulling knitting added regularly. The coils on the original needle are transferred to a new adjacent needle according to the pattern design. The knitting operation of this needle is stopped, and the yarn will display the needle-pulling width according to the number of needle-pulling, forming a concave and convex texture.

[0010] Preferably, the air layer padding structure has bulging and flat parts in the designed pattern, and the waste yarn padded in the bulging position does not participate in the weaving, thereby forming a bulge. This method is very similar to the effect of a woven quilted down jacket, and its special effect is very suitable for the design of a one-piece garment with two wears. Combined with the padding process, the thickness of the air layer structure is increased. This structure feels fluffy and thick, with a flat surface and delicate pattern.

[0011] Preferably, the air layer terry fabric is woven by the front and rear needle plates working together, the rear needle plate weaves a plain stitch to form the ground fabric with one yarn, and the front needle plate weaves a loop fabric with one yarn.

[0012] Preferably, the air layer mesh structure utilizes the surface structure of the air layer to turn the coil from the current needle position to another needle position, and then after the needle bed is moved horizontally, it is turned back to the original needle position. The corresponding needle position to which the coil is turned back is an empty needle, that is, the knitting is started on the empty needle, and the coil will have an effect similar to the tuck structure, which is the mesh structure.

[0013] Preferably, the air layer spacer stitch is added to the interlaced stitch in the weft lining process and the surface stitch. The spacer stitch knitting process is that when the yarn is knitted, any needle adjacent to the front and back does not need to participate in the knitting. After the yarn is hooked into the needle hook of the front needle, it is pulled to the next needle in the form of a floating line to be looped. The fabric forms two loops passing through three needles. The air layer is compounded with a variety of tissue structures, and rhythmic pattern textures are arranged on the surface of the fabric through the various tissues. The yarn tissue characteristics are highlighted and amplified in the development style of the shaped knitted garment.

[0014] A process for knitting air layer tissue of a shaped garment, wherein the specific steps of the process for knitting air layer tissue of a shaped garment are as follows: S1: Digital pattern design: Design digital patterns. The digital patterns are divided into printed and jacquard patterns. The jacquard pattern is divided into cut-pattern and non-cut-pattern parts. The solid color part of the digital pattern is the cut-pattern part, the grayscale image after decolorization of the color part of the digital pattern is the non-cut-pattern part, and the color image after removing the solid color layer and grayscale layer from the digital pattern is the printed pattern. The non-cut-pattern part is consistent with the printed part. S2: jacquard layer structure design: ① Design a shadow weave library for the non-cut pattern part and select a basic weave A. The valid selection range of basic weave A is the twill or satin weave of the original non-cut pattern part. The number of warp and weft weave cycles is the same and is recorded as M. The basic weave is strengthened by 1 in the weft direction to the right to form a group of shadow weaves. All these weaves constitute the shadow weave library, and the number of shadow weaves is M*(M2)+1. ② Design the weave for the shearling part. The jacquard fabric is woven with multiple wefts and warp yarns. According to the design requirements, one of the wefts is selected as the A weft. The ground weave B is drawn at the position where the A weft is interwoven with the warp yarn. All other wefts except the A weft are all warp weave points or weft weave points. The wefts except the A weft are not interwoven with the warp yarn and form floats: S3; Fabric structure design: Decolorize the digital pattern obtained in step S1 to form a grayscale image, and adjust the grayscale level to not exceed the number of shadow and light tissues. Replace the grayscale and shadow and light tissues in the grayscale image one by one to form a non-cut pattern fabric structure image. Fill the pattern solid color part with the corresponding cut pattern fabric structure to form a cut pattern fabric structure image. S4: Weaving: Select the warp and weft according to the texture color effect in the digital pattern design process, set the warp and weft density according to the fabric structure diagram obtained in steps S1 to S3, add the weft selection information to the fabric structure diagram, and weave a jacquard fabric with a shear pattern effect: S5: Cutting flower floating length processing: Performing float trimming on the jacquard fabric of step S4; S6: Printing: According to the texture and layout effect of the jacquard fabric after the float length treatment, the color image obtained in step S1 is kept in the same position and the surface of the jacquard fabric is printed, thus completing the weaving and printing of the finished product.

[0016] The innovative design and development of air layer tissue has promoted the overall innovation of the knitted garment industry and promoted the application of new technologies, new materials and new processes, which helps to enhance the competitiveness of the entire industry and promote industrial upgrading and transformation.

[0017] The innovative design and development of air layer tissue requires mastering advanced textile technology and processes, which helps to improve the company's technical level and R&D capabilities. Through continuous technological innovation and accumulation, the company's core competitiveness can be formed, laying the foundation for future development.

[0018] The innovative design of the air layer structure improves the performance and appearance of knitted garments, thereby increasing the added value of the products. DETAILED DESCRIPTION

[0019] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0020] In the description of the present invention, the indicated orientations or positional relationships are only for the purpose of facilitating the description of the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0021] Example: The present invention provides a technical solution: Based on the analysis of knitted garment theory and flat knitting technology principles, and taking the knitted air layer structure as the theoretical research object, we carry out the production design and knitting development of air layer texture knitted fabric products. The main research ideas and methods are as follows: Firstly, the examples of knitted air layer fabrics are scientifically classified and summarized and their characteristics are summarized. Based on this, the texture of knitted air layer is experimentally explored.

[0022] Secondly, by comparing the cases of knitted air layer texture in terms of different yarns, tissues, etc., the conventional implementation methods and technical skills of knitted air layer texture are refined, summarized and summarized, and the factors affecting its characteristics are explored.

[0023] Finally, from the professional perspective of knitted air layer texture design research, with the texture design application of a series of knitted clothing fabrics as the design direction, the sample design and product development of the air layer texture of flat knitting clothing were carried out, and its air layer texture was further actually applied to the weaving of a series of knitted clothing.

[0024] 1) Structural design Therefore, in the design and weaving of knitted texture effects, utilizing multiple weave arrangements and composite effects can create rich and diverse texture variations, breaking away from conventional design concepts. The application of composite weaves not only enhances the aesthetics of a single weave but also significantly improves the wearability of knitted fabrics, such as breathability, warmth retention, elasticity, and dimensional stability, often with unexpected results. This project explores the application of air layers in combination with other weaves, demonstrating their flexible and versatile application, and rekindling enthusiasm for knitted garment design.

[0025] (1) Air layer organization The localized protrusions, designed on an air-layer jacquard base, are created by adding a spot knitting technique to the raised pattern. Some areas of the upper needle plate have more rows than the lower needle plate. After a regular wash cycle, these areas develop a raised texture, while the normally woven areas become sunken. This striking contrast between the raised and lower surfaces creates a highly decorative, textured effect and a raised feel. This spot knitting technique not only allows for the creation of three-dimensional fabrics but also allows for full-scale weaving, such as pocket openings and placket weaving.

[0026] (2) Air layer needle turning organization Air-layer jacquard, also known as cylindrical jacquard, is knitted with two separate needle plates on each side of the fabric. When the front plate is working, the corresponding rear plate is inactive, creating a two-sided, air-layer jacquard fabric. To enhance the jacquard's three-dimensional quality, the upper needle plate performs the transfer according to the pattern design. Transfer marks can be seen on the back of the fabric, creating a thinner fabric where the needles are transferred, creating a three-dimensional texture suitable for heavy outerwear. The fabric created with transfer stitches has a richer texture, demonstrating the benefits of fabric pattern design on garments, and has become quite popular in the design market in recent years.

[0027] (3) Air layer reverse needle structure The purl effect is added to the air jacquard base. The purl stitch is incorporated into the design of the basic air jacquard pattern module, creating a combination of uneven and convex variations on the fabric surface and color variations. As shown in the figure, the air jacquard is a three-color pattern combined with a purl stitch. Not only does the air jacquard create a delicate pattern, but the orderly arrangement of purl stitches also creates a rhythmic sense of tension and relaxation in the fabric.

[0028] (4) Air layer needle extraction tissue The fabric is knitted with a regular pattern of draw-off stitches, transferring the loops from one needle to a new, adjacent needle according to the pattern design. This needle then stops knitting, and the yarn changes width based on the number of draw-off stitches, creating a textured, concave and convex texture. When knitting with a pattern, appropriate draw-off areas are selected, avoiding the patterned draw-offs. The visual effect from the front differs from that from the side, creating a subtle pattern effect that creates a garment with different appearances from different angles, creating a sense of play and rhythm.

[0029] (5) Air layer yarn structure In the designed pattern, the bulging and flat parts are anticipated, and the waste yarn padded in the bulging position does not participate in the weaving, thus forming a bulge. This method is very similar to the effect of a woven quilted down jacket. Its special effect is very suitable for the design of a one-piece garment with two wears. Combined with the padding process, the thickness of the air layer structure is increased. This structure feels fluffy and thick, with a flat surface and delicate patterns. It is the best choice for autumn and winter shows, and it can take both beauty and functionality into consideration.

[0030] (6) Air layer terry tissue Terry weave is typically knitted by front and back needle plates working together. The back needle plate weaves a single yarn in a flat stitch for the ground weave, while the front needle plate weaves a single yarn in a loop weave. The combination of the air layer and the terry weave adds thickness and texture to the fabric, creating a fluffy, three-dimensional, yet soft and stretchy velvety texture. In clothing design, the air layer, combined with terry and other textured weaves, can create a sense of volume and a unique wool fabric feel, significantly enhancing the texture of knitted fabrics. The terry structure offers a soft, rich feel and is often used in winter clothing designs.

[0031] (7) Air layer floating line organization There are many ways to create a float. The principle of cast-off is similar to that of a needle drop, where some needles are not involved in the knitting process, creating a float. Long loops can be designed to create many interesting fabric variations.

[0032] (8) Air layer mesh structure The mesh effect is achieved by transferring the stitches from one needle position to another using the air layer of the fabric. The stitches are then returned to their original position after a horizontal shift of the needle bed. The stitches are then returned to an empty needle, creating a tuck-like effect. This is the mesh structure. The yarn in the image is relatively finely woven, and the mesh structure creates a subtle contrast and a delicate, soft texture, evoking a soft and romantic quality.

[0033] (9) Air layer spacer tissue The air-layer weft interlining process is combined with the surface weave to incorporate spacer stitches. Spacer stitch knitting involves weaving yarn without any adjacent needles participating in the process. The yarn is hooked on the hook of the first needle and then pulled to the next needle as a floating thread, forming two loops of fabric across three needles. The resulting fabric is generally looser, creating a visible base.

[0034] (10) Air layer and multiple tissue structures The use of multiple weaves is also intended to enhance the fabric's appearance and expand the fabric's variety. By arranging multiple weaves on the fabric's surface to create rhythmic patterns and textures, the yarn's characteristics are amplified and enhanced in the development of custom knitted garments. A single air-layer composite fabric can simultaneously incorporate various weave structures, including tuck, transfer, and embossed. Experimenting with the combination and combination of different weaves in knitted fabric design, and utilizing different machine types and yarns in practice, offers endless possibilities for fabric design.

[0035] 2) Fabric weaving design The project uses the flower cutting process to design the flower cutting texture part of the pattern, showing the unique light and transparent texture or tassel floating effect of the flower cutting fabric, highlighting the visual experience of the weaving and printing combined with the jacquard fabric, and on this basis, combining the printed pattern design to show the rich color effect of the pattern. The designed fabric surface has the dual characteristics of weaving and printing combined to show the unique texture and rich colors of the flower cutting, giving the finished jacquard fabric surface the characteristics of the flower cutting texture and printed colors coordinating to express the same digital pattern: the jacquard part shows the thin and transparent effect or tassel floating effect of the flower cutting fabric, and the printed part cooperates with the jacquard texture color to show the colorful visual effect of the pattern.

[0036] (1)Digital pattern design: Design digital patterns. Digital patterns are divided into printed layer patterns and jacquard layer patterns. The jacquard layer patterns are divided into cut-flowered parts and non-cut-flowered parts. Among them, the solid color part in the digital pattern is the cut-flowered part, the grayscale image after decolorizing the colored part in the digital pattern is the non-cut-flowered part, and the colored image after removing the solid color layer and the grayscale layer in the digital pattern is the printed layer pattern; the non-cut-flowered part is consistent with the printed part (printing layer pattern).

[0037] (2) Jacquard layer organization design: ① Design a shadow tissue library for the non-cut part and select a basic tissue A. The effective selection range of basic tissue A is the twill or satin weave of the original non-cut part tissue. The number of warp and weft tissue cycles is the same and is recorded as M. Strengthen the basic tissue to the right along the weft direction by 1 to form a group of shadow tissues. All of its tissues constitute the shadow tissue library, and the number of shadow tissues is M*(M2)+1.

[0038] ② Design the weave for the shearling part. The jacquard fabric is woven with multiple wefts and warps. According to the design requirements, one of the wefts is selected as the A weft. The ground weave B is drawn at the position where the A weft is interwoven with the warp yarn. All other wefts except the A weft are warp weave points or weft weave points. The wefts except the A weft are not interwoven with the warp yarn and form floats: (3) Fabric structure design: The digital pattern obtained in step (1) is decolored to form a grayscale image, and the grayscale level is adjusted to not exceed the number of shadow tissues, and the grayscale and shadow tissues in the grayscale image are replaced one by one to form a non-cut pattern part fabric structure image, and the solid color part of the pattern is filled with the tissue structure corresponding to the cut pattern part tissue to form a cut pattern part fabric structure image; (4) Weaving: The warp and weft are selected according to the texture color effect in the digital pattern design process, the warp and weft density is set according to the fabric structure diagram obtained in step (1) to step (3), and the fabric structure diagram is added with the weft selection information to weave a jacquard fabric with a shear pattern effect: (5) Floating length processing of cut flowers: The jacquard fabric of step (4) is trimmed for floating length; (6) Printing: According to the texture and layout effect of the jacquard fabric after the float length treatment, the color image obtained in step (1) is kept in the same position and the surface of the jacquard fabric is printed, thus completing the weaving and printing of the finished product.

[0039] Key technologies 1) By changing the weaving method, yarn material and color matching, and adopting a double-layer air layer structure design, a rich variety of air layer structure patterns can be created to form a unique three-dimensional effect, increasing the layering and fashion sense of the clothing. These patterns are not only beautiful and elegant, but also can meet the personalized needs of different consumers.

[0040] 2) By selecting yarns of different materials, specifications and colors, and blending or interweaving yarns of different materials, air-layer fabrics with unique properties and appearance can be created. The use of natural fiber yarns such as wool and cashmere can increase the warmth and softness of clothing, and combined with synthetic fiber yarns, the wear resistance and wrinkle resistance of clothing can be improved.

[0041] 3) Using printing technology on the air layer tissue, various floral, animal or geometric patterns can be printed. Adding various patterns and textures to the air layer tissue can increase the interest and artistic sense of clothing. These patterns and textures can be achieved through weaving methods, printing or embroidery.

[0042] 4) Air layer structure usually adopts three pieces of fabric structure: inner, middle and outer to form an air sandwich, which has a warming effect. Double-layer structure can be used to add additional warp or weft yarns between the inner and outer warp and weft yarns to form a three-layer sandwich structure.

[0043] 5) Combining wool fabric with air layer tissue can form wool air layer fabric, which combines the warmth retention of wool and the breathability of the air layer, and is suitable for making warm winter clothing.

[0044] 6) Breaking through the technical limitations of previous jacquard fabric design methods that combined weaving and printing, where the jacquard layer had too little variation and the fabric texture was flat, the developed jacquard fabric surface has the characteristics of the shearing texture and the printed color coordinating with each other to express the same digital pattern. The jacquard part shows the light and transparent effect or floating tassel effect of the shearing fabric, and the printed part and the jacquard texture color cooperate to express the colorful visual effect of the pattern. Because the shearing pattern, non-shearing pattern and printed pattern are treated with each other's effects in the design process, the shearing texture and printed color of the designed fabric surface can be perfectly combined, coordinating with each other to express the texture and colorful effect of the same pattern. 7) Through the innovation of this project, no matter how the digital pattern theme changes, it can be used to design jacquard fabrics that combine cut-out textures with printed colors, thus meeting the technical requirements of mass production.
