Problems solved by technology

[0003] The Chinese invention with the publication number CN101037810A relates to a production process of colorful polyester embroidery thread, which is colored by adding masterbatch in the melt spinning process (dope coloring), and the prepared colorful polyester embroidery thread, One is that there are many kinds of embroidery threads that have not been dyed in the subsequent process, and the production response is not flexible enough; the other is that the invention adopts the two-step method of winding and then drawing, and the production cost is not economical enough; the third is that the invention The raw materials used are ordinary polyester chips without modification treatment. The physical properties of the prepared colored polyester embroidery threads are quite different, and the fields of use will also be different.

Abstract

The invention belongs to the chemical fiber manufacturing field, and particularly relates to a production method of a spunbonded viscose polyester embroidery thread. The production method comprises the following steps: preparing bright modified polyester; carrying out melt spinning, drawing and winding to obtain modified polyester drawn yarns according to the characteristics of the bright modified polyester; and twisting the modified polyester drawn yarns, and dyeing the yarns to obtain the colored polyester embroidery thread product. The invention further provides the colored polyester embroidery thread prepared by the production method. The colored polyester embroidery thread is bright polyester fibers with a triangular cross section, and has bright color; the obtained embroidery thread has the advantages of complete color spectrum, rich color and higher color fastness, and is not darkened after being washed; and meanwhile the embroidered pattern is not deformed due to low boiling water shrinkage and stable structure.

Description

Technical field [0001] The present invention is a chemical fiber manufacturing field. It specially involves a production method of a stable and rich -colored imitation adhesive polyester embroidery line and a product obtained by the production method. Background technique [0002] The price of adhesive embroidery lines is more expensive. After the embroidery type has been washed several times, it is easy to deform, which affects the beauty of the flower type.In addition, in the production process of sticky fibers, a large amount of alkalinity is used, which has serious environmental pollution and production is limited by national policies.By using modified polyesterly developed embroidery lines, the cost is greatly reduced than adhesive fiber. More importantly, the entire production process has a very small environmental pollution and recycled and reuse, which is in line with the concept of environmental protection.The embroidered color of the imitation polyester embroidery line ...
