Heating device of chemical fiber draw texturing machine and chemical fiber draw texturing machine

Abstract

The invention discloses a heating device of a chemical fiber draw texturing machine, and belongs to the field of textile draw texturing equipment. The heating device includes a walking filament tube which is hollow on the inner side, chemical fiber passes through the walking filament tube and is subjected to heating, the heating device also includes an electric heater for heating the walking filament tube, and a steam pipe; the chemical fiber is located between the steam pipe and the inner wall of the walking filament pipe, steam outlets are formed at interval in the steam pipe in the walking filament direction of the chemical fiber, and the steam passes through the steam pipe and is discharged from the steam outlet to heat the chemical fiber. Additionally, the invention also discloses the chemical fiber draw texturing machine which adopts the heating device. The heating device and the chemical fiber draw texturing machine have the advantages that the heating temperature of the chemical fiber is more easily controlled and the effect of draw texturing is better.

Description

【Technical field】 [0001] The invention relates to a heating device of a texturing machine for chemical fiber filaments, which belongs to the field of textile filament texturing equipment. 【Background technique】 [0002] The texturing process of textile silk is to use heating and stretching to make the textile silk have a certain degree of elasticity. This kind of tow is more commonly used in the field of socks and other clothing. In the texturing process, the heating part is a relatively important link. , and the temperature control and humidity control in the heating process are also very critical. If the temperature control and humidity control are not well controlled, it will greatly affect the final elasticity of the textile yarn. [0003] The existing texturing machine technology on the market usually adopts two methods of electric heating or steam heating, but the two methods also have certain disadvantages in actual production. If the method of electric heating is onl...

Problems solved by technology

[0003] The existing texturing machine technology on the market usually adopts two methods of electric heating or steam heating, but the two methods also have certain disadvantages in actual production. If the method of electric heating is only used, the humidity will not be enough. A state of "dry" heating and "dry" stretching will eventually lead to the problem of poor elasticity of the textile yarn and easy to break, and if it is an electric heating method, the temperature needs to be strictly controlled. If it exceeds 150°, it will have a great impact The properties of textile yarn, if the temperature is too low, the effect of stretching and elastication will not be achieved; and if it is simply heated by steam, it will lead to excessive humidity, excessive elasticity after stretching and retraction, and excessive elasticity. Too big and not enough toughness
