Abstract

The invention relates to a sea-island type spunbond filament non-woven material and a manufacturing method of the sea-island type spunbond filament non-woven material. According to the conception of the designing scheme of the method, one polymer suitable for being used as the double-component or multi-component spinning sea component polymer is adopted as a sea component, such as COPET or PET, one polymer suitable for being used as the double-component or multi-component spinning island component polymer is adopted as an island component, such as PET or PA, corresponding sea-island type spinning components are utilized, a net is directly formed after melt spinning, and the non-woven material is manufactured after reinforcement by one or more of a mechanical net fixing method, a chemical bonding net fixing method and a heat bonding net fixing method.

Description

technical field [0001] The invention relates to a nonwoven material, in particular to a sea-island type bicomponent spun-bonded filament nonwoven material and a manufacturing method thereof. Background technique [0002] Sea-island composite superfine fiber is a new type of fiber developed in the early 1970s. Due to its extremely small monofilament fineness and large specific surface area, it has many excellent properties that conventional fibers do not have, such as soft and fluffy, smooth and smooth, Good drape, breathable and comfortable to wear, soft and elegant luster, etc. There are two types of sea-island fiber spinning forming: composite method and blending method. The former uses a composite spinning machine to spin polymer interarranged fibers, in which the dispersed phase melt components are distributed in the other through the composite spinning assembly according to the design. In a continuous phase melt, it is characterized by the excellent performance of the ...
