分丝
Filaments
所渭分丝是指将经过拉伸后的丝束分离成单丝状,以防止成网时纤维相互枯连或约结。常用分找方法有以下儿种。
The dividing line is to separate the towed strand into single filaments, so as to prevent the fibers from drying or closing. There are the following kinds of methods in common use.
气流分丝法
Air separation method
利用拉伸气流在一定形状管道中产生的空气动力学效应.如利用气流的突然扩散等方法进行分丝。
The aerodynamic effect produced by the stretching airflow in a certain shape pipe is divided by using the method of sudden diffusion of air flow.
机械分丝法
Mechanical wire splitting method
使拉伸后的丝条商速地与档板、偏离板或振动板搜击、振动而分离。
The stretched wire is quickly separated from the baffle, the offset plate or the vibrating plate.
无纺布袋定做
强刹带电法
Strong brake belt electric method
在位伸时.让丝束经过一个高达几万伏(甚至更高)的肺电场.使丝条带同种电荷而相斥分离。
When the position is extended, let the tow pass through a lung electric field up to tens of thousands of volts (or even higher).
橄带电法
Olivine method
利用丝条在拉伸过粉中相互雌擦产生的静电而分丝。为增加丝条的带电强度,对纤维截面有一定选择,同时还可以在高繁物中加人一些能增加静电作用的添加剂。成网
The wire is used to separate the silk from the static electricity produced by the female wiping in the powder. In order to increase the electrification intensity of the wire, there is a certain choice of fiber cross section, and some additives which can increase the static electricity can be added to the high complex. Netting
成网也叫铺网。经拉伸、分丝后的长丝必须均匀地铺到成网帘上,成网的关健是对长丝的运动进行控制.其控制方式主要有以下两种。
The net is also called the network. After drawing, the filament must be spread evenly to the net curtain, and the Guan Jian of the net is the control of the motion of the filament. The main control methods are the following two kinds.
气流控侧
Airflow control side
级简单的一种是利用拉伸气流在出口处形成的某种规律运动,使长丝按一定规律(例如圆周运动)铺放到凝网帘上。还有一种是利用侧吹气流
