Aqueous microfiber with PET masterbatch, knowing, come together to understand its background technology and technology to achieve elements!
Background technique:
Ultrafine fiber synthetic leather is considered to be the third-generation synthetic leather technology, and is a typical representative of synthetic fibers to high imitation. Since it is capable of simulating the structure of leather fibers, the relevant R & D and industrial application work is widely concerned. The preparation of ultrafine fiber-colorant needs to be impregnated, dried, reduced, dyed, and water washing, etc., in order to eventually achieve high simulation fiber structure, which in turn makes high simulation super-fiber products. Typically, in the reduction mode, ultrafine fibers can be divided into two types of toluene reduction and alkali reduction type, that is, so-called "oily" (toluene amount) and "water-based" (alkali decrease) super Fiber. "Water-based" ultravah is less affected by the environment due to the solvent used during the manufacturing process, and therefore, it has been greatly concerned in recent years, and the water-based microfib can be divided into the non-woven base material used. Nylon type and polyester type.
Polyester type "water-based" ultrastructure, since the effect of polyester (PET) molecular structure is not dyed. On the one hand, traditional water-soluble dyes cannot effectively adsorb them on PET molecules, and the dispersion dyes have a certain dyeing ability, which can be combined with fibers and polyurethanes into molecular weight (Van Dehua Li), but the final product is also easy to migrate. And other issues. On the other hand, since the application of the aqueous ultrapopropic fiber is late, it is currently lacking PET masterbatch particles for the aqueous ultra-fiber system, which uses general-purpose PET masterbatch, due to its ordinary polyester fiber, in double Compatibility, dispersibility, and uniformity in the aqueous microfiber spinning process, breaking the wire, and the color cannot meet the requirements after reducing the open fiber.
Based on the above, the present invention proposes a water-based ultrafine fiber PET masterbatch and a preparation method thereof, which can effectively solve the above problems.
Technology implementation factors:
It is an object of the present invention to provide a aqueous ultrafine fiber PET color masterbatch and a preparation method thereof. The aqueous ultrafine fiber of the present invention uses PET color parent particles, and the coloring and color migration of the final product can be solved by the addition of the color parent particles in the spinning stage. At the same time, the color masterbatch is low, the coloring effect is good, and the production and preparation process is simple, and the environmental pollution is small.
