Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of textiles, and specifically relates to a single-sided structured flannel, in particular to a flannel weaving device using a single-sided machine. Background Art
[0002] Circular knitting machine, scientifically known as circular weft knitting machine, has many advantages such as multiple loops, high speed, high output, fast pattern change, good fabric quality, fewer processes, strong product adaptability, etc., and has been widely used in the knitting industry. Circular knitting machine includes single-sided circular knitting machine and double-sided circular knitting machine. Double-sided circular knitting machine has two needle cylinders, one upper needle cylinder (commonly known as needle disk) and one lower needle cylinder, and they are vertically arranged to each other, that is, the needle disk and needle cylinder are vertically arranged at 90 degrees.
[0003] Double-sided cloth is a woven fabric. In the prior art, in the process of weaving double-sided cloth, the double-sided cloth is subjected to a napping treatment, which needs to be done on a specific napping device. After the napping treatment, the yarn on the reverse side of the double-sided cloth will be messy and easy to fall off, affecting the quality of the double-sided cloth.
[0004] Using a double-sided machine to weave a single-sided structure can make full use of the lower needle plate of the double-sided machine as a napping structure, which can realize the simultaneous weaving of the base fabric and the velvet cloth, and improve the reliability of the velvet cloth. There is no weaving device and method for weaving a single-sided velvet fabric using a double-sided machine in the prior art. Utility Model Content
[0005] The utility model aims to solve the above problems in the prior art and proposes a single-sided structure flannel weaving device for a double-sided machine.
[0006] The purpose of the utility model can be achieved through the following technical solutions: a single-sided structure velvet weaving device of a double-sided machine, comprising a frame, a needle disk and a needle cylinder are provided on the frame, the needle disk is provided with knitting needles for weaving a base yarn and a knitting needle triangle for driving the knitting needles to move, and it is characterized in that the needle disk is also used for weaving terry loops for forming velvet, the needle cylinder is provided with a hook knife for pulling the terry loops formed on the needle disk and a cutting knife for cutting the terry loops pulled by the hook knife, and the frame is provided with a hook knife triangle for driving the hook knife to pull the terry.
[0007] In the above-mentioned single-sided structure velvet weaving device of a double-sided machine, the hook knives are in a group of two, and a cutting knife is provided between the two hook knives.
[0008] In the above-mentioned single-sided structure velvet weaving device of a double-sided machine, a napping track is provided on the hook knife triangle, and the cutter is fixed in position. When the hook knife pulls the velvet downward along the napping track, the velvet loop hits the cutter to cut the velvet loop into velvet.
[0009] In the above-mentioned single-sided structure velvet weaving device of a double-sided machine, the distance between the hook knife and the cutting knife blade when it drops to the lowest point is the delayed cutting distance, and the delayed cutting distance is the distance of 1-5 needles of terry. When the hook knife is pulling the terry, it is used to stretch the wool yarn into a loop, and then cut the terry loop to form velvet. When the wool yarn is looped, it continues to weave 1-5 loops. The first loop that has been looped must have been locked. At this time, the loop is cut off, so that the loop after cutting has been embedded in the bottom yarn and continues to complete the loop of 1-5 needles. After the wool yarn is cut, the tail is firmly locked and it is not easy to fall off.
[0010] In the above-mentioned double-sided machine single-sided structure velvet weaving device, the distance between the hook knife and the cutting knife blade when the hook knife descends to the lowest point is 0.1-0.3mm. According to the material, length and count of the wool yarn, the distance between the cutting knife blade and the lowest point of the hook knife pulling can be adjusted to facilitate cutting of different types of velvet.
[0011] The method for weaving a single-sided structural flannel of the double-sided machine comprises the following steps:
[0012] S1, needle disc weaving single-sided bottom yarn;
[0013] S2, the needle disc embeds the wool yarn while weaving the bottom yarn, and forms a loop with the bottom yarn on the needle disc, so that the cut pile yarn is embedded in the bottom yarn of the needle disc;
[0014] S3, when the knitting needles on the needle disc are stretched out to form loops, the hook knife on the needle cylinder hooks the main wool yarn and stretches it downwards, forming a fleece loop after finishing;
[0015] S4, after the base yarn and the wool yarn are looped 1-5 times continuously, the first loop of terry is squeezed down by the following loops until it contacts the blade on the cutter, cutting the wool yarn to form cut loop pile.
[0016] Compared with the prior art, the utility model utilizes the needle cylinder of the double-sided machine to pull and cut the wool yarn during needle disc weaving, thereby weaving the wool yarn into the base yarn, and forming cut loop pile after cutting. The formed pile is firmly embedded in the base yarn and is not easy to fall off; and because the cutting action of the cutter has a delay, the pile loop has formed 1-5 circles behind it when it is cut, ensuring that the pile loop is locked before being cut, further improving the stability of the connection between the wool yarn and the base yarn.
