Problems solved by technology

Due to the addition of a water washing process in this solution, the operation process is time-consuming and laborious, the output is low and the cost is high, and the oil on the fiber cannot be thoroughly washed, and there are still some residues, and the washed water cannot be recycled, which is a waste of water resources. and not environmentally friendly
The second option is to dry-stretch and crimp the raw fiber extruded from the spinneret without contacting any solution during the production process, and the produced fiber is completely oil-free, but the oil-free fiber produced by this program The surface of the tow will be fuzzy, and it is easy to break and generate static electricity during the production process. The broken ends and static electricity will cause frequent roll winding, difficult to continue production, low output and poor quality

preparation example Construction

[0023] Such as figure 1 As shown, the embodiment of the present invention provides a method for preparing an electrostatic fiber, comprising the following steps:

[0024] Add the raw material and electrostatic masterbatch into the extruder to form the primary fiber, and the primary fiber passes through the oil agent roller, the godet roller, the first drafting machine, the second drafting machine, the third drafting machine, the stacking machine, After the crimping machine and the heat setting machine, the fiber bundles are obtained, and the fiber bundles pass through the cutting machine to obtain electrostatic fibers; wherein, the oiling agent on the oiling roller is replaced with water, and between the oiling agent roller and the godet roller, two traction Water spray units are added to the drawing machine, three drafting machines, and the front end of the crimping machine to spray water to the fiber bundles, and a spray unit is added to the tail end of the heat setting mach...

Embodiment 1

[0045] Add polypropylene Z30S raw material and electrostatic masterbatch (addition amount is 5%) into the extruder to form the primary fiber, and the primary fiber passes through the oil agent roller, the godet roller, the first drafting machine, the second drafting machine, Fiber bundles are obtained after the three-pass drafting machine, stacking machine, crimping machine, and heat setting machine, and the fiber bundles pass through a cutting machine to obtain electrostatic fibers; wherein, the oiling agent on the oiling roller is replaced with water, and the oiling agent on the oiling roller Between the fiber bundle and the godet roller, at the second drafting machine, at the third drafting machine, and at the front end of the crimper, add water spray points to spray water to the fiber bundles, and add water spray points at the end of the heat setting machine to Spray water mist on the fiber bundle. The specific parameters of each link are shown in Table 2. In this table, t...

Embodiment 2

[0050] The 2D electrostatic fiber prepared in Example 1 and the 2D oil-containing fiber prepared by the original normal oiling (the difference between the production process of the normal oil-containing fiber and the production process of the electrostatic fiber is that the spinning aid used in the production process is oil agent or water, and other processes are exactly the same) from the four aspects of linear density, breaking strength, elongation at break, and oil content, and the comparison data is shown in Table 3 and Table 4.

[0051] Table 3 Performance data of 2D electrostatic fibers

[0052]

[0053] Table 4 Performance data of 2D oil-containing fibers

[0054]

[0055] From the comparison of the data in Table 3 and Table 4, it can be seen that the oil content of the electrostatic fiber is 0%, that is, there is no oil agent, and the breaking strength and elongation at break of the fiber basically do not change. And because the electrostatic fiber does not cont...

Abstract

The invention provides a preparation method of electrostatic fiber and a product thereof and belongs to the method of fiber preparation methods. The production method is continuously stable, and the obtained product is completely oil-free and high in electrostatic adsorption. In the technical scheme, oil agent applied to an oil roller is replaced with water, water spraying units are respectively added to positions between the oil roller and a godet roller, a two-way drafting machine, a three-way drifting machine and the front end of a crimping machine to spray water to fiber bundles, and a spray unit is added to the tail end of a heat-setting machine to spray water mist to the fiber bundles. The preparation method can be applied to the production and processing of electrostatic fiber and electrostatic non-woven cloth or complete electrostatic non-woven cloth.

Description

technical field [0001] The invention belongs to the field of fiber preparation methods, and in particular relates to an electrostatic fiber preparation method and a product obtained therefrom. Background technique [0002] In the process of chemical fiber spinning, in order to ensure that the fibers have smooth, bundled, antistatic and other properties, oils are commonly used. However, some chemical components in the oil are harmful to the human body. For example, when chemical fibers using oil are processed into non-woven fabrics for food, medicine or air filtration, certain chemical components in the oil will enter Food, medicine or air are absorbed by people, endangering people's health; when chemical fibers using oil are used to process hemp fiberboard, glass fiberboard or other automotive interior materials, the chemical components in the oil will also It emits a harmful smell to the human body and endangers people's health. [0003] In the prior art, in order to remo...
