Abstract

The invention relates to a composite nonwoven fabric for desiccant packaging and a preparation method thereof. The composite nonwoven fabric is composed of component A and component B, wherein the component A is PET spunbonded nonwoven fabric, the component B is PET/PE or PP/PE bicomponent spunbonded nonwoven fabric. According to the invention, the PET nonwoven fabric and PET/PE or PP/PE bicomponent spunbonded nonwoven fabric are subjected to bump press roll direct hot pressing compounding to obtain a packaging material special for high strength desiccants. The packaging material can be directly used for heat sealing, and can adapt to the use requirements of automated high-speed production equipment, and the self-strength is higher than that of domestic nonwoven fabrics. By adopting the nonwoven fabric direct heat compounding technology, the composite nonwoven fabric has no pollution to the environment, is odorless, tasteless and non-corrosive, has good air permeability and soft texture, is not brittle, and has dust prevention performance higher than that of domestic nonwoven fabrics.

Description

technical field [0001] The invention relates to a nonwoven fabric, in particular to a composite nonwoven fabric (Weina I type) used for desiccant packaging and a preparation method thereof. Background technique [0002] With the widespread use of desiccant packaging, it is required that the desiccant packaging material itself has higher strength and can better adapt to the requirements of high-speed automatic production equipment. The desiccant packaging material is required to be safe, reliable, and stable in performance during use. [0003] Composite non-woven fabric is a new type of packaging material. Non-woven fabrics and other fabrics can be compounded in various ways, such as film coating, hot pressing, glue spraying, ultrasonic treatment, etc. Through compounding, two or three layers of fabrics can be compounded together, so that Produce products with special functions, such as high strength, high water absorption, high barrier properties, high hydrostatic pressure ...
