Problems solved by technology

However, the defect of the above-mentioned production process is that the organic solvent (such as ethyl acetate, acetone, etc.) of the glue solution in the fiber rod must be heated and volatilized cleanly during drying, causing environmental pollution, and drying and curing will also consume a lot of energy. cause waste of energy
[0003] In addition, the use of the above-mentioned microporous fiber rod is made by bonding the fiber filaments to each other with an adhesive. It will degumming, soften and swell when it works in an organic solvent; , Perfume sticks (tablets), quantitative liquid-taking sticks, etc. will be degummed, softened and swelled when soaked in alcohol organic solvents, resulting in unsatisfactory use effects and short service life

Abstract

The invention provides a method for manufacturing a microporous fiber bar. The method includes the following steps that firstly, polymers of two components continuously form composite fibers for a skin layer and a core layer correspondingly in the longitudinal direction of fibers; secondly, a plurality of skin-core composite fiber filaments are selected to be combined into a skin-core composite fiber filament bundle; and thirdly, the skin-core composite fiber filament bundle is made to pass through a mold with the proper temperature at a proper speed, the surface layers of skin layer materials of the surface-core composite fiber filaments are melted or semi-melted, and the surface-core composite fiber filaments are promoted to be bonded together to form the microporous fiber bar. The filaments are bonded mutually after the copolyester materials of the skin layers of the skin-core composite fibers are heated to be melted or semi-melted, and thus the procedures of impregnation, drying, curing and the like in existing manufacturing technologies are omitted, environment pollution and energy waste are avoided, more energy is saved, and the environment is better protected.

Description

technical field [0001] The invention relates to the field of microporous technology, in particular to a microporous fiber for a marker tip (a part used for writing on a writing or drawing pen), a water diversion core, a perfume stick, an incense stick (sheet), and a quantitative liquid-taking stick. Bar stock production method. Background technique [0002] Microporous fiber rods, through the principle of capillary phenomenon produced by the micropores in the fiber rods, liquids with a certain viscosity range such as ink, water, and solvents (these liquids can contain solid particles with a certain diameter) from one end of the rods Suction to the other end. Using this principle, microporous fiber rods can be cut and ground into different shapes and sizes of nibs (the part used for writing on writing and painting pens), water diversion cores, perfume sticks, and incense sticks ( Tablets), Quantitative Liquid Dispensing Sticks and other products. The production process of ...
