Problems solved by technology

However, if the process is not properly controlled, the spinnability and dyeing effect will be greatly reduced
The production of deep-dyed slices is unstable, which makes the dyeing stripes blurred and not clear enough in the production process

Abstract

The invention discloses a production method of PA56 / PA6 bio-based splendor stripe composite elastic nylon yarns, which comprises the following steps: adding bio-based slices, compounding common nylon slices, optimizing the production process, producing bio-based splendor composite yarns through high-speed spinning, and controlling the network air pressure to obtain the PA56 / PA6 bio-based splendor stripe composite elastic nylon yarns. The bio-based splendor stripe composite elastic nylon yarn fiber capable of meeting the development requirements of high-end markets is researched and developed on an elasticizer through a one-step tensile deformation technology. According to the invention, the style of the special-shaped color strip of the product is ensured, the production of the product is more stable, the strip style is clearer, the performance is greatly improved, and the development of the product adapts to the current international trend of energy conservation and environmental protection, so that the product has a wide market prospect.

Description

technical field [0001] The invention relates to the technical field of synthetic fiber production, in particular to a production method of PA56 / PA6 bio-based colorful stripe composite elastic nylon yarn. Background technique [0002] Cailisi fabric has a colorful pattern style of dyeing different colors. The length and pattern of the stripes can be adjusted according to the aesthetic and visual requirements, which can meet the user's visual aesthetic requirements, and the hand feels soft and smooth, and the moisture absorption effect is remarkable. [0003] In 2017, the scientific and technological achievements Nylon Cailis, developed by our company, are made of two kinds of PA6 slices with different color absorption effects (one of the raw materials is PA6 deep-dyed slices), which are produced by melt blending technology. The product has a two-color effect and has been widely used. [0004] However, from the perspective of the long-term mass production process, the product...
