Description
Technical Field
The utility model relates to an air jet loom especially relates to an air jet loom for weaving cotton flannel.
Background
At present, flannelette is mostly woven by a shuttle loom, but the rotating speed of the shuttle loom is slow, the noise is large, the weaving efficiency is low, the problem of cloth cover wool boards is difficult to avoid, the working environment is poor, and the labor for stopping the vehicle is more and more difficult. The pile fabric is composed of an upper layer of fabric, a lower layer of fabric and a middle pile warp, the requirement for the warp is changed from the original warp into two kinds of warp, the warp feeding speed of the pile warp determines the height of the raised pile, the warp feeding speed of the pile warp needs to be kept constant in the process of weaving the pile fabric, and the phenomenon of high and low pile can not occur, so that the basic requirement for weaving the pile fabric is that the tension of the ground warp is uniform, the position of the pile warp is accurate, and the height of the pile can be adjusted. Therefore, the textile industry tends to use air jet looms to weave flannelette more and more, but the conventional profiled reed for the air jet loom is used for beating up, in the actual beating-up process, due to the existence of the weft shrinkage, edge warp yarns continuously rub the profiled reed in the beating-up process, reed blades contacting left and right yarns are gradually ground into yarn marks, and reed teeth of the profiled reed are broken when serious, so that the weaving cost is increased. In addition, when the flannelette is woven, the problem of width shrinkage is serious, in order to ensure the quality of the cloth cover, a temple is required to be arranged at a cloth fell, so as to achieve the purpose of propping up the cloth and preventing the cloth from shrinking, the holding force of the temple of the prior air jet loom is far from meeting the requirement, thereby causing a series of problems of serious defects of the temple, reduced quality, increased warp and weft, low efficiency, serious damage of the reed, shortened service life of the reed and the like, and the air jet loom depending on air flow for weft insertion, because the weft is always led from the left end to the right end of the weaving machine to form rough edges, in order to realize the cloth supporting function, the waste selvages at two sides are penetrated during weaving to realize the connection of the upper layer and the lower layer, after the waste selvages are separated from the weaving opening by a certain distance to finish the cloth supporting function, the waste selvages are cut off by scissors, the edge shearing mode increases the labor intensity of operators, the edge shearing width is different, and the weaving quality is influenced.
It will thus be seen that the prior art is susceptible to further improvements and enhancements.
