X号， 发 明名称为 "一种卷曲涤纶长丝的生产设备"的专利申请中公开了一种 热风喷吹加热生产卷曲涤纶长丝的设备，该设备在实际应用中所存在 的不足是， 结构复杂、 不易操作和丝束卷曲弧度不能人为控制等等。 发明内容  In the production technology of the conventional crimped polyester spinning, as disclosed in the patent application No. 200620086094. X, entitled "Production Equipment for a Curly Polyester Filament", a device for producing a crimped polyester filament by hot air blowing is disclosed. The shortcomings of the device in practical applications are that the structure is complicated, the operation is not easy, and the curl curvature of the tow cannot be artificially controlled. Summary of the invention
本发明的目的是提供一种结构简单、 易于操作， 自动化程度高、 可同时生产多种不同卷曲效果的卷曲涤纶长丝的方法及设备。该方法 是按以下方式实现的： 将涤纶纺丝机纺出的涤纶长丝进行分组， 一组 或多组丝束绕经加热辊进行加热，然后将加热时间不同的两组丝束合 并绕制成纺织丝饼供织机纺织使用，由于加热过程中局部改变涤纶长 丝的物理特性，所以用加热处理过的涤纶长丝纺织成的织物经沸水处 理后便具有了自然卷曲的物理特性。  SUMMARY OF THE INVENTION It is an object of the present invention to provide a method and apparatus for a crimped polyester filament having a simple structure, easy handling, high degree of automation, and simultaneous production of a plurality of different crimping effects. The method is realized in the following manner: the polyester filaments spun from the polyester spinning machine are grouped, one or more sets of tows are heated by the heating roller, and then the two sets of tows with different heating times are combined and wound. The woven silk cake is used for weaving textiles. Because the physical properties of the polyester filaments are locally changed during the heating process, the fabric woven from the heat treated polyester filaments has the physical properties of natural curl after being treated by boiling water.
由于丝束的卷曲角度是根据加热辊的直径而定，所以只要更换不 同直径的加热辊或调整不同的加热温度，即可生产相同和不同卷曲效 果的涤纶长丝。  Since the crimp angle of the tow is determined by the diameter of the heating roller, polyester filaments of the same and different crimping effects can be produced by simply replacing the heating rolls of different diameters or adjusting different heating temperatures.
具体步骤是： 将涤纶纺丝机喷嘴喷出的涤纶丝分成两组丝束， 将 两组丝束分别在转动的加热辊上缠绕一圈或两圈，经加热过的两组涤 纶丝束合并绕制成纺织丝饼送织机编制成织物， 织物经沸水处理后， 涤纶长丝或其编织的织物即产生自然卷曲，加热辊表面的温度控制在 100— 120°C。 附图说明 如附图 1所示， 两组丝束在不同直径的加热辊上分别缠绕不同圈 数进行加热的设备结构示意图； The specific steps are as follows: the polyester filaments sprayed from the nozzle of the polyester spinning machine are divided into two sets of tows, and the two sets of tows are respectively wound on the rotating heating roller for one or two turns, and the heated two sets of polyester tow are combined. The fabric is processed into a woven fabric into a woven fabric. After the fabric is treated with boiling water, the polyester filament or the woven fabric thereof is naturally curled, and the temperature of the surface of the heating roller is controlled at 100-120 °C. DRAWINGS As shown in FIG. 1 , a schematic structural view of a device in which two sets of tows are respectively wound on different heating rolls of different diameters for heating;
如附图 2所示， 两组丝束在直径相同的或不同的两根加热辊上缠 绕加热的实施方式示意图。  As shown in Fig. 2, a schematic view of an embodiment in which two sets of tows are wound around two heating rolls of the same or different diameters.
