Sizing Agent Spraying Assembly

System Composition of the Sizing Agent Spraying Assembly

It consists of a high-pressure pump, an atomizing nozzle, an air pressure stabilizing device and a mist collection & recovery tank.

The sizing agent is delivered to the nozzle by the high-pressure pump, atomized into droplets with a diameter of 5–20 μm, and then sprayed onto the high-speed running yarn. Excess mist droplets are collected by the recovery tank.

The sizing agent spraying assembly consists of a high-pressure pump, an atomizing nozzle, an air flow stabilizing device and a mist collection & recovery tank.The high-pressure pump delivers the sizing agent to the nozzle, which atomizes it (droplet diameter: 5–20 μm) and sprays it onto high-speed running yarns. Excess mist droplets are collected by the recovery tank.

Core Features

High Productivity Adaptability

A single atomizing nozzle can cover 5–10 parallel yarns, and one spraying unit can support the synchronous production of 20–30 yarns.It is suitable for large-scale roving production lines (such as direct yarn and spraying yarn), with a productivity 5–10 times that of a titration system.

Strong Process Flexibility

By adjusting the nozzle pressure (0.2–0.5 MPa), spray angle (30°–90°) and the distance between yarns and the nozzle (5–15 cm), it can quickly adapt to yarns of different specifications (such as heavy denier yarns with filament diameter of 13–24 μm), and even realize layered spraying of different sizing agents.

High Environmental Sensitivity

The atomization effect is easily affected by workshop wind speed (distribution is affected at ≥0.5 m/s) and temperature (droplet viscosity changes when temperature difference exceeds 5 ℃), which may lead to a deviation in yarn oiling uniformity of up to 3%–5%.In addition, about 10%–15% of mist droplets will drift, so a supporting mist collection device is required to avoid waste and pollution.
