Network oiling method

Abstract

The invention relates to a method for adding oil to network, in particularly a network adding oil method that filament middle, high speed spinning generates network and processes pulverization adding oil to filament. Compressed air is blowed in a network device filament channel for ejecting filament in the filament channel, accordingly generating transverse impact to open and dispersedness, occurs higher-mode vibration to confound and wind which has characteristics that: a pulverization oil agent is inlet in the filament channel, direction of inlet is in conformity with the direction of the compressed air blowing in or in side direction of the compressed air blowing in, position of the pulverization oil agent inlet in the filament channel leans to filament inlet port side of the filament channel and is not lower than position of the compressed air blowing in. The method solves problems that many friction points, large filament intension and large filament beam cross section or uneven adding oil to filament beam when monofilament amount is large caused by two working procedures of network and adding oil separated in filament high speed spinning normal production, remedy shortage of large friction force between filament beam and air caused by later filament beam adding pre-network in normal spinning and delaying filament beam amplexus.

Description

technical field [0001] The invention relates to a network oiling method, in particular to a network oiling method for atomizing and oiling filaments while producing a network by medium and high-speed spinning. Background technique [0002] During spinning, usually filament oiling and network creation are performed separately. Use oil nipples or tankers to oil the filaments to increase the cohesion of the filaments, reduce static electricity and play a lubricating role. Then use the network device to generate network nodes on the filaments, thereby increasing the cohesion of the filaments, and at the same time, the oil agent inside the filaments is homogenized by high-speed airflow. The traditional spinning line requires two devices to complete the oiling and the generation of network nodes, resulting in many friction points on the line and poor cohesion of the tow, which in turn increases the tension of the sliver and affects the product quality.

Problems solved by technology

The invention solves the problems of many friction points, large filament tension, large cross-section of tow or uneven oiling of tow caused by the separation of the two processes of netting and oiling in the conventional production of high-speed filament spinning. At the same time, the network generated earlier improves the cohesion of the filaments, reduces the contact surface area between the filaments and the air, thereby reducing the tension on the filaments, and makes up for the late pre-network of the filaments in conventional spinning, which delays the filament The tow is not tightly entwined, resulting in insufficient friction between the tow and the air
