Abstract

The invention discloses a method for utilizing plastic bottles to prepare non-woven fabric. The method includes the steps of (1) after the plastic bottles are cut into shreds, conducting treatment for removing taints and oil, putting the plastic bottle shreds into warm water, adding sodium hexafluorophosphate into the water, and taking out the plastic bottle shreds to conduct drying treatment after 25-35 min; (2) after the dried plastic bottle shreds are blended with addictives, conducting prilling, and then conducting melt-blow spinning to obtain finished products, wherein the weight ratio of the plastic bottle shreds to the addictives is 50-55 to 1. The method for utilizing the plastic bottles to prepare the non-woven fabric has the advantages of being simple in process procedures, capable of reducing production costs of the non-woven fabric effectively, and providing a new approach to development and utilization of waste plastic, and the non-woven fabric prepared according to the method is excellent in mechanical properties and long in service life.

Description

technical field [0001] The invention belongs to the field of non-woven fabric preparation, and in particular relates to a method for preparing non-woven fabric by using a plastic bottle. Background technique [0002] Discarded plastic bottles are a cheap plastic raw material. In order to reduce production costs and reduce environmental pollution, discarded plastic bottles can be used as raw materials for preparing non-woven fabrics. Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. They are a new generation of environmentally friendly materials. Low cost, recyclable and so on. For example, polypropylene pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. It is called cloth because of its appearance and certain properties. However, using waste plastic bottles directly as raw materials to make non-woven fabrics has ...
