A petg-based rapid prototyping wig fiber and its preparation process

Abstract

The invention provides a PETG-based rapid prototyping wig fiber and its preparation process, comprising the following weight proportions: PETG 65-95%, flame retardant 5-15%, antibacterial agent 3-9%, dyeing agent 1-3%, Additive 4‑5%, dispersant 2‑3%. The wig fiber obtained in the present invention has the characteristics of antibacterial and flame retardant, high luster, easy dyeing, soft hair, good durability, easy processing of various complex shapes, etc., and has good market competitiveness. The invention also provides its preparation process, which improves the traditional preparation process, utilizes the characteristics of PETG material that is easy to be thermally processed, and performs heat setting process under the intelligent heating system of the hot roller of the drafting machine, so as to improve the processing speed and increase the toughness and durability of the product. Spend.

Description

technical field [0001] The invention relates to the technical field of artificial wigs, in particular to a PETG-based rapid prototyping wig fiber and a preparation process thereof. Background technique [0002] With the rapid development of the economy and the improvement of people's living standards, wigs have become a must-have accessory for people to pursue individuality, and at the same time provide convenience for some people in need. With the development of cultural industries such as film and television, drama, and cosplay , the demand for wigs is also increasing day by day, and the wig market has a broad prospect. [0003] At present, the vast majority of artificial wigs are mainly made of synthetic fibers, and the commonly used raw materials for making wigs are PVC, PP, PET, and PBT. This kind of wig fiber has poor stability to light and heat during production and use, limited mechanical strength and flexibility, narrow processing range, and most of the processes m...

Problems solved by technology

[0005] In the production process of PETG's rapid prototyping wig fiber, after the oil roller oils the virgin fiber, it needs to be stretched. On the one hand, it is to filter out the oil, and on the other hand, it is stretched again to make it Meet the predetermined quality requirements, but in the process of stretching, due to the excessive length of the silk fiber, the silk fiber will be loose, which will easily cause the phenomenon of uneven stretching and easy knotting of the silk fiber, and it needs to be adjusted for different silk fibers Stretching strength; currently, the silk fiber stretching method in the market is relatively traditional. Stretching it through two pressure rollers cannot achieve tension on the silk fiber, which often leads to knotting of the silk fiber and uneven stretching In some cases, the knotting of silk fibers may cause the chemical fiber to break during stretching, which will affect the quality of silk fibers. In severe knotting, it is necessary to stop the line to adjust the knotted silk fibers, which will affect the production efficiency of wig fibers; and for different The silk fiber needs to adjust the gap between the pressing rollers. The traditional pressing rollers cannot adjust the gap between the pressing rollers, resulting in uneven drafting and squeezing of the wig fiber and affecting the quality of the wig fiber.
