Production method of imitated printed fabric

Abstract

The production method of the imitated printed fabric comprises the following steps that weaving is conducted, specifically, first yarn is stacked above second yarn to form true color yarn, the first yarn and the second yarn are yarn of two colors, and a first pattern area is woven through the true color yarn; the reversing device is rotated to enable the second yarn to be overlapped above the first yarn to form reverse color yarn, a second pattern area is woven through the reverse color yarn, and a third pattern area is woven through the true color yarn and the reverse color yarn alternately; the first pattern area, the second pattern area and the third pattern area form the imitation printing fabric. A first pattern area woven by the front-color yarn, a second pattern area woven by the reverse-color yarn and a third pattern area woven by the front-color yarn and the reverse-color yarn together form a pattern with three colors. After being woven, the fabric has three colors of patterns, further printing or embroidering is not needed, and the production cost is reduced. And the patterns are formed by yarns, so that the air permeability is good, and the texture is clear.

After the fabric is woven, it has a three-color pattern, and no further printing or embroidery is required, which reduces production costs. Moreover, the pattern is composed of yarn, has good air permeability, and clear texture.

[0006] Preferably, the method further comprises the following steps: Image processing: decolorize the image and decompose it into the first pattern, the second pattern, and the third pattern according to the grayscale level. Data processing, pasting the picture on the fabric model, and calculating the first needle information, the second needle information, and the third needle information according to the positions of the first pattern, the second pattern, and the third pattern on the fabric model; In the weaving step, the flat knitting machine weaves the first pattern area according to the first needle output information, weaves the second pattern area according to the second needle output information, and weaves the third pattern area according to the third needle output information.

[0007] Through pattern processing and data processing, data for producing patterned fabrics can be quickly generated. After the data is imported into the flat knitting machine, the production of the fabric can be completed.

[0008] Preferably, the steering device includes a turning plate and a steering motor, the steering motor is used to drive the turning plate to rotate, both ends of the turning plate are provided with wire holes, the first yarn and the second yarn respectively pass through the wire holes at both ends of the turning plate, and rotating the turning plate can switch the upper and lower positions of the first yarn and the second yarn.

[0009] Preferably, in the weaving step, the following steps are also included: A rotating shaft is arranged in the middle of the rotating plate, and the rotating plate can rotate around the axis of the rotating shaft. A channel is arranged at the axis of the rotating shaft. After the third yarn is glued on the glue disc, the third yarn passes through the rotating shaft from the channel and extends into the middle of the first yarn and the second yarn. The first yarn, the third yarn, and the second yarn are sequentially stacked to form a positive color yarn, and the second yarn, the third yarn, and the first yarn are sequentially stacked to form a reverse color yarn. The third yarn extends into the middle of the first yarn and the second yarn to form a positive color yarn or a reverse color yarn, and the yarn pressing device performs point pressing on the positive color yarn or the reverse color yarn from the upper and lower directions.

[0010] The third yarn is used for bonding the first yarn and the second yarn, so that the positive color yarn and the reverse color yarn composited by the first yarn and the second yarn are firm and not easy to twist.

[0011] Preferably, the third yarn comprises hot-melt yarn, and after the weaving step is completed, the imitation printed fabric is sent into the steam chamber for shaping, and the temperature in the steam chamber is greater than the melting point of the hot-melt yarn.

[0012] After the hot-melt yarn is melted, the first yarn and the second yarn can be bonded together, thereby reducing the misalignment of the first yarn and the second yarn during the subsequent use of the fabric.

[0013] By adopting the above technical solution, the beneficial effect of the present invention is that the present invention forms a three-color pattern through the first pattern area woven by the positive color yarn, the second pattern area woven by the reverse color yarn, and the third pattern area woven by the positive color yarn and the reverse color yarn. After the fabric is woven, it has a three-color flower pattern, and no further printing or embroidery is required, thereby reducing production costs. Moreover, the flower pattern is composed of yarn, has good air permeability, and has clear texture. BRIEF DESCRIPTION OF THE DRAWINGS
