Abstract

The invention discloses a method for preparing non-woven fabrics by using waste plastic bottles, which comprises the following steps: (1) Cut the plastic bottles into pieces and perform decontamination and oil removal treatment, then put them into warm water, and add hexafluoro Sodium phosphate, after 25‑35min, take out the plastic bottle and carry out drying treatment; (2) Mix the dried plastic bottle fragments with additives, granulate, and then carry out melt-blown spinning to obtain a finished product, in which the plastic bottle fragments are mixed with additives The weight ratio of additives is 50‑55:1. The method for preparing non-woven fabrics by using plastic bottles provided by the invention has simple process steps, can effectively reduce the production cost of non-woven fabrics, and the prepared non-woven fabrics have excellent mechanical properties and long service life, and are suitable for the development and utilization of waste plastics. A new way is provided.

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 ...
