The invention relates to a method for manufacturing a cationic vortex spinning woven fabric. The cationic vortex is spun out at a certain speed by drawing cationic polyester fibers and viscose fibers on a drawing frame according to the ratio. Spun single yarn, after warping, paralleling, and sizing, obtain the catabolic vortex spun single yarn as the warp beam of the cationic vortex spun woven fabric, and use the single warp beam loom to make the above-mentioned cathodic vortex spun single yarn Warp threads and other raw materials are used as weft threads, which are woven into one according to the requirements of different tissues. After secondary light desizing, secondary dyeing and drying, the dyed cathodic eddy current woven fabric is obtained. The cathodic vortex woven fabric prepared by this method is suitable for clothing fabrics, with smooth surface, soft hand feeling, excellent anti-pilling, washability and hygroscopicity, which is better than ordinary polyester-viscose fabrics in surface quality. Improvement, cost reduction, saving the energy consumption of two-for-one twisted strands, improving the various index requirements of fabrics, suitable for large-scale fabric processing and weaving.

The invention provides an active continuous warp feeding system for carbon fiber weaving. The active continuous warp feeding system comprises a frame, a first reed combination, an upper yarn guide roller combination, a rubber guide roller, a first stainless steel yarn guide roller, a second reed combination, a second stainless steel yarn guide roller, a tension balance device, a third stainless steel yarn guide roller and a fourth stainless steel yarn guide roller. A motor drives the rubber guide roller to rotate at a constant speed, a certain quantity of fibers are fed into the tension balance device due to the friction force between the rubber guide roller and the fibers, the warp tension is finely adjusted through lubrication of the vertical positions of the yarn guide rollers, and it is guaranteed that warp yarns can be fed to the weaving process at even and constant tension. The active continuous warp feeding system avoids the problems that a passive warp feeding device feeds warp yarns to a weaving machine through a winding mechanism, the winding mechanism is seriously abraded, and the quality of cloth is deteriorated.

The invention relates to a textile, in particular to a preparation method of fabric woven by a rayon vortex spinning machine, which is widely used in garment fabric. The fabric is interwoven by warp and weft, the warp is rayon vortex spun single yarn and the weft is polyester silk or wrap silk with combination of the polyester silk and spandex. The preparation method comprises the steps of drawing, vortex spinning, batch warping, re-beaming, sizing, drafting and reeding, weaving, pretreatment of dyeing and finishing, dyeing and setting. The fabric woven by the rayon vortex spinning machine is suitable for the garment fabric, smooth in surface, flabby in hand feeling and excellent in anti-pilling property, washing fastness and moisture absorption; compared with ordinary polyester-viscose fabric, the cloth surface quality is improved, the cost is relatively reduced, the energy consumption for double-twisting for forming the twisted yarn is saved and the index requirements in multiple aspects can be improved while reducing the cost.

The invention provides a double-nozzle multi-yarn weaving device, which includes a weft feeder, a main nozzle, a sub-nozzle, a heald frame, and a sliding module; the sub-nozzle is placed between the main nozzle and the warp opening; the The sliding module includes a sliding track, a spring, and a movable block. The auxiliary nozzle is slidably assembled on the horizontal sliding track. The auxiliary nozzle is connected to the movable block through a spring. The movable block is assembled on the frame. The lower part is designed with a knocking plate extending vertically downwards, and the front part of the knocking plate is designed with a cam that rotates from the axis, and a proximal end and a distal end are designed on the cam; the far end of the cam rotates Can be tapped onto the pad. In this way, the sub-nozzle can greatly increase the injection speed of the weft yarn, and also greatly improve the simultaneous conveying capacity of single or multiple weft yarns, and improve the surface quality of the gray cloth.

The invention discloses a pneumatic pressing and ironing machine for clothing printing and ironing. The pneumatic pressing and ironing machine comprises a rack, a pressing and ironing table, a pressing and ironing device and a clamping device. The pressing and ironing device comprises an upper pressing and ironing plate, a lower pressing and ironing plate and a pressing and ironing air cylinder. The bottom face of the upper pressing and ironing plate is provided with a limiting protruding block, a clamping groove and an air outlet hole. A guiding device is arranged between the upper pressing and ironing plate and the lower pressing and ironing plate. The clamping device comprises a clamping air cylinder, an upper air clamp and a lower air clamp.

The invention relates to a method for manufacturing polyester vortex spun fabrics. The raw slivers of polyester fibers with cations are drawn on a drawing frame to obtain cooked slivers of polyester fibers, and the polyester vortex spun single yarns are spun at a certain speed, and are finished. Warp, parallel, and sizing to obtain polyester vortex spun single yarn as the warp beam of polyester vortex spun fabric, use single warp beam loom to use polyester vortex spun single yarn as warp, and other raw materials as weft, according to different requirements. As a whole, the polyester vortex woven fabric is obtained through secondary light desizing, disperse dyeing and drying; the polyester vortex woven fabric woven by this manufacturing method is suitable for clothing fabrics, with smooth surface and soft hand feeling. It has excellent anti-pilling, washability and moisture absorption. Compared with ordinary polyester-viscose fabrics, the surface quality is improved, the cost is reduced, and the energy consumption of the process of twisting into strands is saved.
