This invention discloses a textile bleaching device, comprising a bleaching box, connecting columns mounted on both sides of the top of the bleaching box, and a spray box mounted on top of the connecting columns. The spray box contains a spray trough, and two forward and backward rollers are rotatably mounted on both sides of the spray trough. Baffles are mounted on the front and rear sides of each roller, and a liftable pressure plate is installed between the front and rear baffles. A guide pipe is installed at the bottom of the spray box. This textile bleaching device, equipped with rollers, pre-winds half of the textile fabric onto one roller during bleaching, while the other half is immersed in the bleaching tank. The end of the immersed textile fabric is pulled up and fixed onto the other roller. Thus, when the two rollers rotate synchronously, one roller places the textile fabric into the bleaching tank, while the other roller winds up the textile fabric in the bleaching tank. After winding up half of the textile fabric, the rotation direction of the rollers is changed, and the bleaching process is repeated cyclically.

The invention discloses a textile bleaching device, and relates to the field of textile processing, the textile bleaching device comprises a rinsing frame body injected with bleaching mixed liquid and textile fabric soaked in the bleaching mixed liquid, the rinsing frame body is internally and fixedly provided with a plurality of groups of limiting cylinder bodies which are linearly distributed at equal intervals, and the limiting cylinder bodies are fixedly arranged in the rinsing frame body. A plurality of sets of limiting cylinders are arranged in the rinsing frame, a hollow pressing plate is further placed on the upper end face of each set of limiting cylinders, and the textile fabric is clamped between the hollow pressing plates and the limiting cylinders in an unfolded state. The bleaching mixed liquid can repeatedly penetrate through the interior of the textile fabric, and even if the textile fabric with large thickness is rinsed, the uniformity of bleaching the interior of the textile fabric can be guaranteed.

The invention relates to the technical field of textile printing and dyeing pretreatment aids, in particular to an oxygen bleaching aid as well as a preparation method and application thereof. The oxygen bleaching aid comprises the following components in percentage by mass: 2-8% of an isomeric alcohol ether surfactant, 18-35% of polycarboxylate, 3-8% of a magnesium salt synergist, 8-18% of sodium gluconate and the balance of water. By adopting an isomeric alcohol ether type surfactant system, the alkali-resistant bleaching agent has excellent alkali-resistant stability and can stably play a role in a common high-alkali environment for textile bleaching. Through the synergistic effect of the magnesium salt synergist, polycarboxylate and sodium gluconate, metal ions in the bleaching liquid can be efficiently chelated, dispersed and blocked, disordered generation of HO. Free radicals is inhibited, invalid decomposition of hydrogen peroxide is reduced, and the bleaching effect is fully guaranteed; meanwhile, attack of free radicals on cellulose fiber molecular chains can be reduced through the synergistic effect, the fiber protection effect is remarkably improved, fabric holes caused by fiber damage are effectively avoided, and the quality of finished fabric products is improved.

The invention belongs to the field of rinsing devices and processes of textile fabrics, and particularly relates to a device for rinsing the textile fabrics and a using method of the device. The device for rinsing the textile fabric comprises a rinsing part, a power part, an equalizer, a gas-liquid mixing mechanism, a diffusion pipe, a throttling orifice plate, ozone gas, a filter, a cooling part, a rinsing solution and a washing part. And a diffusion pipeline is arranged in the rinsing part. The diffusion pipeline is provided with two rows of water through holes, one end of the diffusion pipeline is a liquid inlet, the other end of the diffusion pipeline is a plug, the diffusion pipeline and each row of water through holes are arranged at intervals, the hole opening positions of each row of water through holes are arranged in a staggered mode, and the staggered distance is 1 / 8-1 / 2 of the hole pitch. The opening positions of the water through holes are symmetrically distributed within the range of 180-360 degrees from the view angle of the cross section of the diffusion pipeline. The device is applied to textile bleaching, and has the characteristics of short bleaching time, strong bleaching capability, small damage to textile, high production efficiency, low energy consumption and the like.

The invention relates to the technical field of textile material processing, and discloses a textile bleaching tank, which comprises a bleaching pool, a plurality of groups of guide roll shaft groups are arranged in the bleaching pool, and the guide roll shaft groups enable a textile material to be fully bleached in the bleaching pool; a liquid stirring assembly is arranged between every two guide roller shaft groups, and the liquid stirring assemblies stir the bleaching mixed liquid to beat the textile materials; the liquid stirring assembly comprises liquid stirring teeth, the liquid stirring teeth are rotationally connected with the side wall of the bleaching pool through a liquid stirring shaft, and the spiral directions of the liquid stirring teeth at the two ends of the liquid stirring shaft are opposite, so that the bleaching mixed liquid is collected towards the middle part while the bleaching mixed liquid is stirred; a partition plate is arranged at the bottom of the guide roller shaft group, and a mixing assembly is arranged at the bottom of the partition plate. The textile materials are conveyed into the bleaching pool from one side of the bleaching pool through the conveying roller shaft set, are conveyed in the bleaching pool in a shape like a Chinese character'ji 'under the action of the guiding roller shaft sets and then are conveyed out of the bleaching pool from the conveying roller shaft set on the other side, and bleaching of the textile materials is achieved.
