Problems solved by technology

On the one hand, traditional water-soluble dyes cannot be effectively adsorbed on PET molecules, and disperse dyes have a certain dyeing ability. Although they can form intermolecular forces (Van der Waals forces) with fibers and polyurethane, the final product is also prone to color migration. And other issues
On the other hand, since the application of water-based superfiber started later than that of oil-based superfiber, there is currently a lack of PET masterbatches for water-based superfiber systems, and the use of general-purpose PET masterbatches is aimed at ordinary polyester fibers. During the spinning process of the water-based superfiber of the components, problems such as poor compatibility, dispersion and uniformity, broken filaments, and failure of the color to meet the requirements after fiber reduction and opening are prone to occur.

Abstract

The invention discloses a PET color master batch for water-based superfine fibers. The PET color master batch comprises the following raw materials in percentage by mass: 30-80% of a carrier, 10-50% of a coloring agent, 3-15% of a dispersing agent, 3-15% of a compatibilizer, 3-10% of a slip agent, 3-20% of an antistatic agent, 0.5-20% of modified inorganic filler and 0.1-1% of an antioxidant. By adopting the PET color master batch for water-based superfine fibers, the performances of superfine fiber spinning, non-woven fabric processing and the like are guaranteed, and the problems of coloringand color migration of a final product are solved. The PET color master batch for water-based superfine fibers is low in cost, strong in coloring agent and carrier effect, good in coloring effect, simple in production and preparation process, small in environmental pollution, good in compatibility and liquidity in the spinning process and not prone to yarn breakage, and the final product is stable in hue and free of color migration.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PET color masterbatch for water-based superfine fibers and a preparation method thereof. Background technique [0002] Microfiber synthetic leather is considered to be the third generation of synthetic leather technology, and it is a typical representative of the development of synthetic fibers towards high simulation. Because it can simulate the structure of dermal fibers, related research and development and industrial application work have attracted wide attention. The preparation of microfiber synthetic leather needs to go through processes such as impregnation, drying, weight reduction, dyeing, washing, etc., to finally obtain a structure similar to the collagen fiber structure of dermis, and then to obtain highly simulated microfiber leather products. Generally, according to the different methods of weight reduction, ultrafine fibers can be divided into two typ...
