Multifunctional cooler, spinning equipment and preparation method of C-shaped oil absorption fibers

Abstract

The multifunctional cooler comprises an air ring and a fixed flange ring, the air ring is of an annular shell structure with the bottom closed and the top open, the air ring is detachably arranged on the lower annular face of the fixed flange ring, and the air ring and the fixed flange ring coaxially and jointly define a circular inner cavity; an air inlet is formed in the outer ring wall of the air ring, the inner ring wall of the air ring is a circular step type concave surface, and the bottom surface of each step is an annular plane; an air outlet is formed in the inner ring wall of the innermost step; the inner cavity is provided with a multi-stage air slowing device, and the inner cavity is divided into a labyrinth-shaped air duct by the multi-stage air slowing device; a spraying device is arranged on the inner ring surface of the innermost air buffering plate; the invention further discloses spinning equipment and a preparation method of the C-shaped oil absorption fiber. The spinning equipment comprises a spunbond non-woven fabric testing machine, a spinning plate and a multifunctional cooler. The cross section of the C-shaped oil absorption fiber is C-shaped, and submicron apertures are formed in the C-shaped oil absorption fiber. The preparation method has the beneficial effects that the profiled fiber with good oil retention capability and strong oil absorption performance is prepared.

Description

technical field [0001] The invention belongs to the field of fiber manufacturing, and in particular relates to a multifunctional cooler, spinning equipment and a preparation method for C-shaped oil-absorbing fibers. Background technique [0002] The leakage of marine commodity oil and the accidents of merchant ships are the main causes of marine commodity oil pollution, and it has become a major problem in the world. With the busy sea transportation, oil tanker leakage accidents often occur. A large amount of oil enters the ocean, which has a huge impact on marine life, fisheries and the marine environment and marine ecosystem. In order to reduce the pollution to the ocean, after the oil spill occurs, effective measures must be taken to remove and recover it quickly. The most commonly used measure for oil spills at sea is to use oil booms to limit the spilled oil within a certain range for removal and recovery. Among the various treatment methods, the physical adsorption ...

AI Technical Summary

Problems solved by technology

Among them, the cooling of the fiber is the key to ensure the shape of the fiber. The existing cooler only plays a simple cooling role, and the effect of retaining the shape of the fiber is not good, and the shape of the fiber cannot be adjusted.
