Description

Technical Field

[0001] The invention belongs to the technical field of ribbed fabric manufacturing, and in particular relates to a method for manufacturing a ribbed fabric with a double-twisted group heavy weft structure. Background Art

[0002] Silk fabrics are divided into silk and satin according to their different weave structures. Among them, there is a thin and perforated fabric called leno, which has a unique weave structure. When interlaced with the weft, the twisted warp and the adjacent ground warp are twisted left and right, thus forming a weave with twisted holes on the silk surface. Leno fabric is a very technical category.

[0003] Because traditional leno jacquard weaving is limited by the technology of modern new large jacquard faucet (double-action opening) mechanism, it can only use (original single-action opening) jacquard faucet for jacquard weaving. The old-fashioned (single-action opening) jacquard faucet has a smaller pattern width due to the limited number of pattern needles. When the warp density is very high, only simple and smaller pattern widths can be made, which looks simple and monotonous. Moreover, leno fabrics have always been mainly thin and perforated. Therefore, general twisted warp fabrics can only be used for spring and summer clothing fabrics. Now, twisted warp fabrics that return to traditional culture and give it innovative meanings have become the choice of modern young people in pursuit of silk fabrics. Based on this, the research and development of leno fabrics in autumn and winter is a necessary choice in silk technology. A method for making leno fabrics with a double-twisted group heavy weft structure is urgently needed. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the traditional leno jacquard weaving is limited by the technology of the modern new large jacquard faucet (double-action opening) mechanism, and can only use the (original single-action opening) jacquard faucet for jacquard weaving. The old-style (single-action opening) jacquard faucet has a limited number of pattern needles and the pattern width becomes smaller. When the warp density is very high, only simple and small-width patterns can be made, which looks simple and monotonous. A method for making leno fabric with a double-twisted group heavy weft structure is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical scheme: a method for manufacturing a ribbed fabric with a double-twisted group heavy weft structure, comprising the following steps: S1, a method for twisting two strands of warp independently by using a double twist assembly; S2, using a double twisted group structure to weave high warp and weft density ribbed fabric; S3, performing two-warp twist weaving to form a twisted hole pattern; S4. Produce floral fabrics with high warp and weft density and multiple weft structures.

[0006] As a further description of the above technical solution: In S2, the double-twisted group structure is to use two twisted harnesses to hang together in the installation design, and its function is: when used in the weaving of high warp and weft density floral fabrics, it can overcome the limitations of small number of jacquard dragon head pattern needles and small pattern width. The double-twisted group structure is used to install the jacquard dragon head pattern needle number unchanged, so that the pattern width is increased by 50%.

[0007] As a further description of the above technical solution: In S3, each of the double twist groups is provided with 4 jacquard heddles, into which 4 warp threads are inserted, and 2 independent warp threads are inserted into 2 twist heddles to perform two-warp twist weaving to form a twisted hole pattern.

[0008] As a further description of the above technical solution: In S3, two-warp twist weaving is adopted, so that in the jacquard opening movement, the warp twist is ensured to be twisted according to the designed pattern and the normal jacquard is performed according to the pattern design requirements. The double twist assembly manufacturing method is adopted to ensure that the warp density of the fabric is not affected, and the warp lines corresponding to the twisted heddle and the associated jacquard heddle are more stable than before.

[0009] As a further description of the above technical solution: In S4, the ribbed fabric with a high warp and weft density and a multiple weft structure is produced, and the applied process needs to adopt a high warp and weft density design, specifically: the warp density is more than 70 strands / cm, and the weft density is more than 60 strands / cm. The application of the above process can meet the requirements of thick characteristics and usage functions of the fabric in autumn and winter.

[0010] As a further description of the above technical solution: In S4, the double weft structure of the ribbed fabric made of the multi-weft weave structure can be designed to be double weft, triple weft or above for flexible use. Each weft thread can be individually made with different processes and different colors, and with a reasonable weft density to meet the different functional requirements of the fabric.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: In the present invention, the method adopts a double-twisted group manufacturing method to twist, and the flower width of the flower can be increased by 50% under the condition that the number of original jacquard dragon head needles remains unchanged, the fabric pattern content is increased, and the jacquard pattern is richer. It not only has the characteristics of the traditional Luo structure, but also expands the application range of the Luo fabric process, and can make flexible use of various tissue structures to make the fabric appearance more diverse. The high warp and weft density of the method adopts a heavy weft tissue structure to make the fabric more compact and thick, and can be designed to flower Luo fabrics with a density of more than 26 mommes according to different usage functions. The realization of the double-twisted group heavy weft structure flower Luo fabric fills the gap in the fabric category of Luo fabric in autumn and winter. The fabric technology of the method uses a high weft density heavy weft tissue structure and the flexible use of wefts of different processes to expand the scope of technical application of process design, structural design and other technical applications of fabrics to meet the different functional requirements of the market.

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 creative work are within the scope of protection of the present invention.

[0014] See also Figure 1 The present invention provides a technical solution: a method for manufacturing a ribbed fabric with a double-twisted group heavy weft structure, comprising the following steps: S1, a method for twisting two strands of warp independently by using a double twist assembly; S2. Double twisted group structure is to use two twisted healds to hang together in the design. Its function is: when used in the weaving of high warp and weft density brocade fabrics, it can overcome the restriction of small number of jacquard dragon head pattern needles and small pattern width. The double twisted group structure is used to increase the pattern width by 50% while keeping the number of original jacquard dragon head pattern needles unchanged. S3, each of the double twisted groups is provided with 4 jacquard heddles, into which 4 warp threads are inserted, and two independent warp threads are inserted into the twisted heddles to perform two-warp twist weaving to form a twisted hole pattern. The two-warp twist weaving is adopted to ensure that the twisted warps are twisted according to the designed pattern and the normal jacquard weaving is performed according to the pattern design requirements during the jacquard opening movement. The double twisted group manufacturing method is adopted to ensure that the warp density of the fabric is not affected, and the twisted warps corresponding to the twisted heddles and the associated jacquard heddles are more stable; S4. To produce a ribbed fabric with a multiple weft structure and high warp and weft density, the applied process needs to adopt a design with high warp and weft density, specifically: warp density is more than 70 threads / cm, weft density is more than 60 threads / cm. The application of the above process can meet the requirements of thick fabrics and usage functions in autumn and winter. The multiple weft structure of the ribbed fabric made with the multiple weft structure can be designed to be double weft, triple weft or above for flexible use. Each weft thread is produced separately with different processes and different colors, and is matched with a reasonable weft density to meet the different functional requirements of the fabric.

[0015] In the present embodiment, the method adopts the method of double-twisted assembly construction to twist, and the flower width of the flower can be increased by 50% under the condition that the number of original jacquard dragon head needles remains unchanged, thereby increasing the pattern content of the fabric and making the jacquard pattern richer. It not only has the characteristics of traditional Luo structure, but also expands the application scope of Luo fabric technology, and can make flexible use of various tissue structures to make the fabric appearance more diverse. The high warp and weft density of the method adopts the heavy weft tissue structure to make its fabric tighter and thicker, and can be designed to flower Luo fabrics ranging from 26 mommes or more according to different functional uses. The realization of the double-twisted group heavy weft structure flower Luo fabric fills the gap in the fabric category of Luo fabric in autumn and winter. The fabric technology of the method uses high weft density heavy weft tissue structure and flexible use of weft threads of different processes to expand the scope of technical application of fabric process design, structural design and other technical applications to meet the different functional requirements of the market.
