Technical Field
[0001] The present invention belongs to the technical field of textiles. Specifically, it relates to a single-sided structured flannelette, and particularly to a flannelette weaving device and a weaving method using a single-sided machine. Background Art
[0002] The circular knitting machine, scientifically named circular weft knitting machine, has the advantages of a large number of loop-forming courses, high rotational speed, high output, fast pattern change, good fabric quality, few processes, and strong product adaptability, and has been widely used in the knitting industry. The circular knitting machine includes a single-sided circular machine and a double-sided circular machine. The double-sided circular knitting machine has two needle cylinders, an upper needle cylinder (commonly known as the needle disc) and a lower needle cylinder, and they are arranged perpendicular to each other, that is, the needle disc and the needle cylinder are arranged perpendicular to each other at 90 degrees.
[0003] Double-sided fabric is a kind of knitted fabric. In the prior art, during the process of knitting double-sided fabric, raising and brushing the double-sided fabric requires raising on a specific raising device. After the raising treatment, the yarns on the reverse side of the double-sided fabric will be messy and easy to fall off, affecting the quality of the double-sided fabric.
[0004] While using a double-sided machine to weave a single-sided structure can make full use of the lower needle disc of the double-sided machine as a raising structure, and can realize the simultaneous weaving of the base fabric and the flannelette, improving the reliability of the flannelette. There is no such weaving device and method for weaving single-sided structured flannelette fabric using a double-sided machine in the prior art. Summary of the Invention
[0006] The purpose of the present invention is to address the above problems existing in the prior art and propose a single-sided structured flannelette weaving device and a weaving method for a double-sided machine.
[0007] A single-sided structured flannelette weaving device for a double-sided machine includes a frame. A needle disc and a needle cylinder are provided on the frame. Knitting needles for weaving base yarn and knitting needle cams for driving the movement of the knitting needles are provided on the needle disc. It is characterized in that the needle disc is also used for weaving loops for forming flannelette at the same time. A hooking knife for raising the loops formed on the needle disc and a cutting knife for cutting the loops pulled by the hooking knife are provided on the needle cylinder. A hooking knife cam for driving the hooking knife to raise is provided on the frame.
[0008] In the above single-sided structured flannelette weaving device for a double-sided machine, two hooking knives are in a group, and a cutting knife is provided between the two hooking knives.
[0009] In the above single-sided structured flannelette weaving device for a double-sided machine, a raising track is provided on the hooking knife cam. The position of the cutting knife is fixed. When the hooking knife pulls down along the raising track, the loop touches the cutting knife to cut the loop into flannelette.
[0010] In the above-mentioned single-sided structure flannelette weaving device of a double-sided machine, the distance between the hook knife and the position of the cutting knife blade when the hook knife descends to the lowest point is the delayed cutting distance, and the delayed cutting distance is the loop distance of 1-5 stitches. When the hook knife pulls the hair, it is used to stretch the yarn into loops, and then cut the loops to form plush. After the yarn forms loops, continue to weave for 1-5 loops. The first loop that has already formed a loop must have been locked. At this time, cut the loop, so that the cut loop has been embedded in the ground yarn and 1-5 stitches of loop formation have been completed. The tail of the yarn is firmly locked after cutting, and it is not easy to shed hair.
[0011] In the above-mentioned single-sided structure flannelette weaving device of a double-sided machine, the distance between the hook knife and the position of the cutting knife blade when the hook knife descends to the lowest point is 0.1-0.3 mm. According to the different materials, lengths, and counts of the yarn, the distance between the cutting knife blade and the lowest point of the hook knife pulling the hair can be adjusted to facilitate cutting different types of flannelette.
[0012] Another object of the present invention is to provide a method for weaving single-sided structure flannelette of a double-sided machine, including the following steps: S1. Weave the single-sided ground yarn on the needle plate; S2. While the needle plate weaves the ground yarn, embed the yarn and form loops together with the ground yarn on the needle plate, so that the cut pile yarn is embedded in the ground yarn of the needle plate; S3. When the knitting needles on the needle plate protrude to form loops, the hook knife on the needle cylinder hooks the main yarn and stretches it downward, and after finishing, form the pulled loops; S4. After the ground yarn and the yarn continuously form loops for 1-5 loops, the first loop that forms a loop is squeezed and lowered by the subsequent loops until it contacts the blade on the cutting knife, and the yarn is cut to form cut-loop velvet.
[0013] Compared with the prior art, the present invention uses the needle cylinder of the double-sided machine to pull and cut the yarn during the needle plate weaving, so as to weave the yarn into the ground yarn, and form cut-loop velvet after cutting. The formed plush is firmly embedded in the ground yarn and is not easy to shed hair; and because the cutting action of the cutting knife has a delay, 1-5 loops are formed behind the loop when it is cut, ensuring that the loop is locked before being cut, further improving the stability of the connection between the yarn and the ground yarn.

[0014] Figure 1 is a schematic structural diagram of the hook knife and the cutting knife in the present invention; Figure 2 is a schematic diagram of the linkage trajectory of the hook knife triangle and the knitting needle triangle in the present invention; Figure 3 is a schematic diagram of the fabric structure woven by the present invention. DETAILED DESCRIPTION OF THE INVENTION
[0015] The following are specific embodiments of the present invention. In combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.
[0016] As Figures 1-3 shown, a single-sided structure flannelette weaving device of a double-sided machine includes a frame. A needle plate and a needle cylinder are provided on the frame. Knitting needles for weaving the bottom yarn and knitting needle cams for driving the movement of the knitting needles are provided on the needle plate. It is characterized in that the needle plate is also used for weaving the loops for forming fluff at the same time. A shedding knife for pulling the loops formed on the needle plate and a cutting knife for cutting the loops pulled by the shedding knife are provided on the needle cylinder. A shedding knife cam for driving the shedding knife to pull the loops is provided on the frame.
[0017] In the above-mentioned single-sided structure flannelette weaving device of a double-sided machine, the shedding knives are in a group of two, and a cutting knife is provided between the two shedding knives.
[0018] In the above-mentioned single-sided structure flannelette weaving device of a double-sided machine, a pulling loop track is provided on the shedding knife cam. The position of the cutting knife is fixed. When the shedding knife pulls the loops downward along the pulling loop track, the loops are cut by the cutting knife to form fluff.
[0019] In the above-mentioned single-sided structure flannelette weaving device of a double-sided machine, the distance between the position of the shedding knife when it descends to the lowest point and the cutting edge of the cutting knife is the delayed cutting distance, and the delayed cutting distance is the loop distance of 1-5 needles. When the shedding knife pulls the loops, it is used to stretch the yarn into loops, and then cut the loops to form fluff. After the yarn forms loops, continue to knit 1-5 loops. The first loop that has already formed loops in the front must have been locked. At this time, cut the loops, so that the cut loops have been embedded in the bottom yarn and continue to complete 1-5 needles of loop formation. The tail of the yarn is firmly locked after cutting, and it is not easy to shed hair.
[0020] In the above-mentioned single-sided structure flannelette weaving device of a double-sided machine, the distance between the position of the shedding knife when it descends to the lowest point and the cutting edge of the cutting knife is 0.1-0.3 mm. According to the different materials, lengths, and counts of the yarn, the distance between the cutting edge of the cutting knife and the lowest point of the shedding knife pulling the loops can be adjusted to facilitate cutting different types of flannelette.
[0021] Another object of the present invention is to provide a single-sided structure flannelette weaving method of a double-sided machine, including the following steps: S1. The needle plate weaves the single-sided bottom yarn; S2. While the needle plate weaves the bottom yarn, the plush yarn is embedded and forms loops together with the bottom yarn on the needle plate, so that the cut plush yarn is embedded in the bottom yarn of the needle plate; S3. When the knitting needles on the needle plate protrude to form loops, the shedding knives on the needle cylinder hook the plush yarn and stretch it downward, and after finishing, the pulled loops are formed; After the ground yarn and the wool yarn are continuously looped for 1-5 circles, the first looped pile is squeezed and lowered by the subsequent piles until it contacts the blade on the cutting knife, cutting off the wool yarn to form cut pile velvet.
[0022] Compared with the prior art, the present invention uses the cylinder of a double-sided knitting machine to raise and cut the wool yarn during needle disc weaving, so as to weave the wool yarn into the ground yarn, and cut pile velvet is formed after cutting. The formed plush is firmly embedded in the ground yarn and is not prone to shedding. Moreover, due to the delay of the cutting action of the cutting knife, 1-5 circles are formed behind the pile when it is cut, ensuring that the pile is locked before being cut off, further improving the stability of the connection between the wool yarn and the ground yarn.
[0023] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to substitute, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
