Problems solved by technology

[0006] In addition, as shown in Patent Document 2, the long fibers formed by mixing polypropylene fine fibers and polyethylene thick fibers can prevent oil-absorbing materials. The thick fibers are used as bones to solve the problem of compression deformation, but the use of two raw materials with different melting points causes problems. The problem of complex manufacturing methods

Abstract

The invention provides a fiber collector formed by ultra-thin fibers of micro-fibers and which is bulky and high in shape retention, an oil absorbing material using said fiber collector which is highin oil absorbing performance and not easy to collapse and a manufacturing method of the fiber collector. The diameter of the ultra-fine fiber forming the fiber collector is 0.2 to 4 [mu]m. The fiber collector is characterized in that at least a portion of the ultra-fine fibers are assembled in bundles in the longitudinal direction, and at least a portion of the bonded fiber bundles have a diameterof more than 5 [mu]m.

Description

technical field [0001] The present invention relates to a fiber assembly which is used as an oil-absorbing material and a method for producing the fiber assembly. Background technique [0002] It is known to use fibers of various materials and diameters as oil adsorbents in order to recover oil that has flowed onto sea and water surfaces. For example, Patent Document 1 proposes to use a nanofiber laminate of a polypropylene material whose fibers are directly 100 to 500 nm in size as an oil-absorbing material. In patent document 2, it is proposed to use long-fiber non-woven fabric composed of thin fibers of polypropylene and thick fibers of polyethylene as an oil-absorbing material. [0003] [Patent Document 1] JP-A-2013-184095 [0004] [Patent Document 2] JP-A-2014-240537 [0005] However, the laminate of micronanofibers with a fiber diameter of 100 to 500 nm shown in Patent Document 1 is used as an oil-absorbing material, and the fiber strength is very weak, and a slight...
