Abstract
The invention relates to a processing method of chinlon middle and low speed spinning forming which adds a heat stability device based on slice drying, melting, counting, spinning and cooling, the heat stability device can be touch type and non touch type, the touch type heat stability device uses a heating plate or a heating bar for heating, the non touch type heat stability device uses heat conducting oil for heating to increase stability of a fibre structure, accordingly to realize forming and storing of chinlon middle and low speed spinning in condition of normal temperature and normal humidity successfully. The method has advantages of simple structure, high production rate and low process cost.
Description
Technical field: the present invention relates to the processing method of low speed spinning moulding in the polyamide fibre, belong to weaving manufacturing field.
Background technology: nylon fibre coiling and molding when middle low speed spinning must carry out under the steady state at low temperature and high relative humidity, slightly changes and will cause moulding bad, forms substandard products, and this is a well-known general knowledge.Yet low speed fiber in some in particular cases will be made, but enterprise does not have so strict production equipment again, and perhaps for factors such as production cost controls, that just can not produce qualified product.Same this class undrawn yarn also must carry out under specific temperature and humidity when preserving.Otherwise moulding can't be carried out destroyed, unwinding.
Summary of the invention: purpose of the present invention is exactly the processing method that low speed spinning moulding in the polyamide fibre will be provided, and it can overcome the above existing defective well, has easy for installation, characteristics such as production cost is low, production efficiency height.The object of the present invention is achieved like this, the processing method of low speed spinning moulding is on the basis of chip drying, fusion, metering, spray silk, cooling in the polyamide fibre, increase a thermally-stabilised device, described thermally-stabilised device can be contact, also can be contactless type, the employing heating plate of contact or heating rod heating, the employing heat-conducting oil heating of contactless type; Described thermally-stabilised device heated length is controlled at 0.8 meter-2 meters, and heating and temperature control is at 140 ℃ ± 2.5 ℃.The present invention has the production efficiency height, cost is low, does not need just can produce qualified product than higher production equipment and condition.
Description of drawings: Fig. 1 is processing method technological process of the present invention
The specific embodiment: the invention will be further described below in conjunction with accompanying drawing
In the drawings, the processing method of low speed spinning moulding is on the basis of chip drying, fusion, metering, spray silk, cooling in the polyamide fibre of the present invention, increased a thermally-stabilised device, described thermally-stabilised device can be contact, also can be contactless type, the employing heating plate of contact or heating rod heating, the employing heat-conducting oil heating of contactless type; Described thermally-stabilised device heated length is controlled at 0.8 meter-2 meters, and heating and temperature control is at 140 ℃ ± 2.5 ℃.During concrete enforcement, for well, contact easily causes temperature control inhomogeneous and damage fiber to heater with contactless type; Device length can decide according to the thickness of institute's producd fibers, also can regulate temperature under the condition that length is determined just realizes, but length preferably is controlled at about 1.8 meters, cause is less than 0.8 meter being heated evenly property that will be difficult to guarantee monfil, if will bring the height that increases floor and inhale problem such as silk gas consumption greater than 2 meters, influence economy.The temperature difference control of device is preferably in ± and 2.5 ℃.
Processing method of the present invention installs heater additional and is able to smooth moulding under the ambient temperature and moisture condition and deposits to be implemented in the stability that increases fibre structure after cooling stage between the tension adjustment.Heater must cool off behind the fiber cooling forming and before guaranteeing entering the tension adjustment draw-off godet once more, otherwise wrapping wire tension force will be difficult to control.It is low that the present invention has a production cost, the efficient height, and characteristics such as fiberizing is good, and undrawn yarn resting period in natural environment is long, is easy to preserve and processing.
