One-step production line of stretch water-repellent spunlaced nonwovens

The utility model discloses a one-step production line of stretch water-repellent spunlaced nonwovens. The existing spunlaced production line has the defects that spunlaced nonwovens carry certain liquid and are adverse to process control of formulations; most drying units using roller drying are adverse to production of surface treated products. The one-step production line of stretch water-repellent spunlaced nonwovens is characterized by comprising a front pricking liquid roller, a dipping tank, a rear pricking liquid roller, a first drying oven, a second drying oven and a third drying oven, which are sequentially arranged in the conveying direction of the spunlaced nonwovens. Both the first drying oven and the second drying oven comprise boxes and a plurality of linked drying drums disposed in the box bodies. The third drying oven comprises a box, a plurality of drive and driven roller sets disposed in the box, and a high-temperature-resistant net curtain. Excess liquid is removed by the front pricking li
