Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. When an element is said to be "fixed to" another element, it can be by the usual fixed means of welding or bolting or gluing.

[0018] The preferred embodiment of the present invention discloses a hydrophilic melt-blown cloth, the ra...

Abstract

The invention discloses hydrophilic melt-blown cloth and a preparation process thereof, the hydrophilic melt-blown cloth is composed of hydrophilic pp and melt-blown pp, and the hydrophilic pp accounts for 1%-10% of the raw materials of the hydrophilic melt-blown cloth; the percentage of the melt-blown pp in the raw materials of the hydrophilic melt-blown cloth is 90%-99%. The preparation method comprises the following steps: step 1, putting the melt-blown PP master batch and the hydrophilic master batch into a batch feeder according to a ratio of 95: 5, and uniformly mixing the melt-blown PP master batch and the hydrophilic master batch; 2, the mixture obtained in the step 1 is fed into a melt pump to be treated and extruded; 3, carrying out spinning stretching treatment on the extrudate obtained in the step 2 to obtain fibers; and step 4, putting the fibers cooled in the step 3 into a web former to prepare hydrophilic melt-blown cloth, and finally rolling the hydrophilic melt-blown cloth. Water can be allowed to pass through, oil is isolated, and oil-water separation is achieved.

Description

technical field [0001] The invention belongs to the field of melt-blown cloth, and in particular relates to a hydrophilic melt-blown cloth and a preparation process thereof. Background technique [0002] The existing melt-blown cloth has low filtration accuracy and its own water repellency, so the filtration cannot achieve the effect of oil-water separation, and the practical application is not convenient enough. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a hydrophilic melt-blown cloth and a preparation process thereof. [0004] The solution that the present invention adopts for realizing its technical effect is: [0005] Hydrophilic melt-blown cloth, the raw material of which is composed of hydrophilic pp and melt-blown pp, wherein the percentage of the hydrophilic pp in the raw material of the hydrophilic melt-blown cloth is 1%-10%; The percentage of the melt-blown pp in the raw material of the hydr...
