Description

A kind of non-woven cloth and its application in oil hydrosol separation
Technical field:
The present invention relates to technical field of polymer materials, and in particular to a kind of non-woven cloth and its in oil hydrosol separation Application.
Background technique:
Janus type cloth refers to that the two sides of cloth has completely different property, including physical property, chemical property and optics Property etc., the simple superposition of its not instead of two kinds property, the synergistic effect of two kinds of property.Common, hydrophilic-hydrophobic Janus Type cloth has water-wet behavior on one side and another side has hydrophobic property.It is not shown applied to outdoor rain-proof breathable garment or absorbing sweat Wet movement T-shirt.Infant diaper be also using Janus type cloth earlier, it have on one side absorb urine effect and it is another Face has insulating effect, and the two collaboration is played the role of every urine.
Non-woven cloth has the spies such as process flow is short, throughput rate is fast, and yield is high, at low cost, purposes is wide, raw material sources are more Point.The characteristics of not having latitude and longitude due to it, show anisotropy, on the whole for homogeneity it is high, since fiber alignment is opposite Loose, liquid flux is high, but due to the limitation of non-woven cloth performance itself, it is fresh to be applied to sewage treatment, sea pollution by oil time less The industrial circles such as receipts, Petroleum Production.
Summary of the invention:
It is proposed by the present invention the object of the present invention is to provide a kind of non-woven cloth and its application in oil hydrosol separation Non-woven cloth is formed and is prepared by combing-laminating-by the fiber of hydrophobic-lipophilic property and the fiber of demulsification property, is prepared Process need to only adjust raw fibre charge order, little with common non-woven fabric production technology difference, without changing equipment, be suitble to big The industrialized production of scale, while the non-woven cloth has the demulsification of anionic oil-in-water emulsion and selectively realization oil extraction Isolated effect can be widely applied to the industrial circles such as sewage treatment, sea pollution by oil recycling, Petroleum Production and industry demulsification.
The present invention is achieved by the following technical programs:
A kind of preparation method of non-woven cloth, comprising the following steps:
