Definitions

  • the invention belongs to the field of synthetic leather manufacturing, and particularly relates to an aqueous impregnated base fabric for aqueous synthetic leather and a preparation method of the aqueous impregnated base fabric.
  • Breathability and moisture permeability are the eternal pursuit of synthetic leather products.
  • PVA polyvinyl acrylate
  • a film is formed on the surface of the fiber, and a barrier layer is formed during the tanning process.
  • a void is formed between the fiber and the PU to give the finished product a better breathability, moisture permeability and a softer hand.
  • synthetic leather products which are both breathable, moisture permeable, soft, and abrasion resistant are still difficult to meet the needs of large-scale industrial production.
  • Another object of the present invention is to provide a process for preparing the above aqueous PVA impregnated base fabric.
  • the object of the invention can be achieved by the following measures:
  • An aqueous impregnated base fabric prepared by impregnating and sizing an aqueous PVA slurry with a base fabric in a slurry tank, wherein the aqueous PVA slurry is a PVA resin having a mass content of 3 to 5%. Aqueous solution.
  • the chemical name of PVA is polyvinyl alcohol, which is a white solid. It is mainly selected according to the degree of polymerization. In order to facilitate the production of water washing, it is generally selected to have a low degree of polymerization and a low-temperature soluble type. In the present invention, P17 type resin powder of Korea Toyo Chemical Co., Ltd. is specifically selected. Further, the PVA resin in the aqueous PVA slurry has a mass content of 4%.
  • the invention also discloses a preparation method of the above aqueous impregnated base fabric, which firstly dissolves the PVA resin powder in water to a completely transparent aqueous PVA slurry solution, and then moves the solution into the slurry tank to perform immersion sizing with the base cloth. , finally dry.
  • the quality of PVA resin in aqueous PVA slurry solution The content is 3 to 5%, preferably 4%.
  • the PVA resin was P17 type PVA resin powder of Toyo Chemical Co., Ltd. of Korea.
  • the drying temperature should be 130-140 ° C.
  • the sizing amount of the aqueous PVA slurry during the immersion sizing process is tested according to the immersion base cloth weight before and after drying. 9-10 g/m 2 is the best.
  • the impregnated base fabric of the present invention is used for the production of garment leather, sofa, etc. after being washed by tanning, and has better air permeability, and the product feels softer and closer to the leather.
  • the prepared aqueous impregnated base fabric was tested under normal temperature and humidity using a BPDCA IDEALAIR 4PD type gas permeable apparatus, and the air permeability of the cloth was 41 L/mm.
  • the prepared aqueous impregnated base fabric was infiltrated into the moisture permeable cup weighting method by the cup method in the constant temperature and humidity chamber, and the results showed that the cloth had a moisture permeability of 39.6 g/m 2 at 24 h.

Abstract

La présente invention concerne un tissu de base à imprégnation aqueuse et son procédé de préparation. Le tissu de base à imprégnation aqueuse est préparé par imprégnation et apprêtage du tissu de base avec une suspension aqueuse de PVA dans une rainure de suspension puis par séchage ultérieur, la suspension aqueuse de PVA étant une solution aqueuse de résine PVA avec une teneur en masse de 3 % à 5 %. Le cuir d'imitation constitué du tissu de base imprégné de la présente invention possède non seulement une meilleure perméabilité mécanique à l'air, mais possède également une meilleure sensation au toucher, et est plus proche du vrai cuir.
