Problems solved by technology

Some people use the method of processing the fiber on the final product to absorb the essence, but the essence is easy to fall off after washing with water, and the fragrance cannot last long, and some people use the fiber that directly mixes the essence into the polyethylene at the core of the hollow sheath-core composite fiber. Perfuming method, but the fragrance duration of these methods is not long, and the variety of fragrance is also limited, which needs further improvement

Abstract

The preparation method of jasmin essence mother granules for perfuming composite fibre includes the following steps: using the components of methyl dihydrojasmonate, hexyl cinnamic ester, licarcoal, dihydromyrcenol, leaf alcohol and other 10 components to prepare jasmin essence according to its formula; mixing said jasmin essence together with ethylene vinyl acetate copolymer (EVA) granules and heating to make the essence be eneloped in the EVA resin so as to obtain the invented mother granules with jasmin fragrance. The polyester / polypropylene and polypropylene / polyethylene core-sheath composite aromatic short fibre made up by said mother granules can be used as filling material oil quilt, pillow, cushion and toys, etc. or can be used as dress material and internal decorative material.

Description

Technical field: [0001] The invention relates to a preparation method of jasmine fragrance masterbatch suitable for perfuming composite fibers. In particular, jasmine fragrant masterbatch is prepared with specially formulated jasmine essence and strong affinity ethylene vinyl acetate copolymer (hereinafter referred to as EVA). Background technique: [0002] In recent years, aromatic products have enjoyed vigorous growth. Aromatic quilts, aromatic bed sheets, aromatic curtains, aromatic clothing, etc. became popular. Some people use the method of processing the fiber to absorb the fragrance on the final product, but the fragrance is easy to fall off after washing with water, and the fragrance cannot be lasted. Others use the fiber that directly mixes the fragrance into the polyethylene of the hollow core composite fiber core. Adding fragrance methods, but the fragrance duration of these methods is not long, the variety of fragrance is also limited, and further improvement is neede...
