Embodiment 1
[0022] A manufacturing process of hydrophilic and pollution-resistant non-woven fabrics, comprising the steps of:
[0023] (1) Propylene refining:
[0024] Deoxidize, desulfurize, and dehydrate the propylene raw material to be processed before use;
[0025] (2) Preparation of raw materials by mixing:
[0026] a. Put the propylene raw material treated in step (1) into a closed reaction tank, then inject 25% hydrogen and 5% nitrogen of the total volume of the propylene raw material into the closed reaction tank, and then add 0.0004% of the total mass of the propylene raw material. Di-n-octyl phthalate, 0.003% triethylaluminum, 0.0015% p-cyclohexylmethyldimethoxysilane, 0.00025% dioctyl terephthalate, and finally add 1.5 times the total mass of propylene raw materials of cyclohexane;
[0027] b. First heat and keep the temperature in the closed reaction tank at 68°C, keep the pressure in the closed reaction tank at 2.8 MPa, stir at a speed of 1000 rpm for 12 minutes, then rais...

Abstract
The invention discloses manufacture process for skin-friendly fouling-resistant nonwoven fabrics, pertaining to the processing technical field of nonwoven fabrics. The process comprises the following steps: (1) propylene refining, (2) raw material combination and preparation, (3) spinning and fabric making. The manufacture process for skin-friendly fouling-resistant nonwoven fabrics has following beneficial effects: resin preparation and modified process can be combined well; processing property and usage performance of resin matrix are improved; overall manufacturing process is simplified and processing efficiency is integrally increased; and the manufactured nonwoven fabrics has good skin-friendly fouling-resistant performance and has high use value.
Description
technical field [0001] The invention belongs to the technical field of processing non-woven fabrics, and in particular relates to a manufacturing process of hydrophilic and pollution-resistant non-woven fabrics. Background technique [0002] 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. Polypropylenepellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. [0003] The spunbond method is one of the main production methods of non-woven fabrics, and the non-woven fabrics it produces also occupy the largest market share. It uses polyester fibers (polyester) and polypropylene fibers (polypropylene) as materials to make continuous long 1. The short fibers are arranged in a net structure during the spinning process, and the ne...
