Composite fiber yarn capable of volatilizing fragrance and performing biodegradation as well as preparation technology and use technology of composite fiber yarn

Abstract

The invention discloses a composite fiber yarn capable of volatilizing fragrance and performing biodegradation. The composite fiber yarn comprises a fiber yarn core and an outer mixing layer wrappingthe outer part of the fiber yarn core; the outer mixing layer is formed by mixing a polymer with a flavoring substance; the flavoring substance is a perfume additive or a perfume microcapsule; the fiber yarn core is a single filament yarn or a filament yarn bundle kinked by multiple filament yarns and is made of a biodegradable material; during manufacturing, the outer mixing layer is produced bywrapping the outer surface of the fiber yarn core with a molten state mixture or mixed solution; and during application, the composite fiber yarn can be applied to a fragrance production component inthe cigarette field. The design can inhibit unnecessary volatilization of perfume, enables the perfume to more uniformly volatilize during application, is relatively strong in environmental protectionproperty and relatively high in working efficiency and is suitable for scale production.

Description

technical field [0001] The invention relates to a composite fiber yarn, in particular to a biodegradable composite fiber yarn capable of volatilizing fragrance, and its preparation and application process, which is particularly applicable to the ones that can suppress unnecessary volatilization of fragrances and ensure relatively low volatilization of fragrances during application. uniform. Background technique [0002] At present, consumers' demand for tobacco fragrance is becoming more and more diversified. The smoke flavor produced by traditional pure tobacco can no longer meet the demand of the market. Especially in high-end cigarettes, cigarettes with differentiated flavors not only reflect the product image and personality It also enriches the brand connotation and improves the price level of the products. [0003] The commonly used way of adding spices to cigarettes is to spray the flavors on the shredded tobacco, and use the shredded tobacco as a carrier for attachm...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the defects and problems existing in the prior art that the unnecessary volatilization of spices cannot be suppressed, and the volatilization of fragrances is uneven during application, and to provide a method that can suppress unnecessary volatilization of fragrances and relatively uniform volatilization of fragrances during application. The volatile fragrance and biodegradable composite fiber yarn, and its preparation and application process
