Abstract
The invention discloses an antibacterial spinning oil suitable for acetate fibers for cigarette filter sticks, which comprises an emulsifier, mineral oil, a fat-soluble antibacterial agent and water or water containing the water-soluble antibacterial agent, wherein the spinning oil before phase inversion and the phase inversion water or the water containing the antibacterial agent are subjected to phase inversion in the water or the water containing the water-soluble antibacterial agent, and the mass ratio of the spinning oil before phase inversion to the phase inversion water or the water containing the antibacterial agent is (1-49): (99-51). The spinning oil is transparent water-in-oil liquid before phase inversion, and is oil-in-water type white emulsion after phase inversion, and the fat-soluble antibacterial agent is one or more of benzoic acid, sorbic acid, ethyl p-hydroxybenzoate and propyl p-hydroxybenzoate. The spinning oil has excellent antibacterial performance, and the spinning oil is not layered before and after phase inversion and can be stored for a long time.
Description
Technical Field
The invention relates to a spinning oil for acetate fibers, in particular to a bacteriostatic spinning oil for acetate fibers for cigarette filter sticks.
Background
Spinning methods of chemical fibers can be basically classified into two types: melt spinning and solution spinning. The spinning oil is an auxiliary agent for reducing static electricity and friction coefficient among fibers in the spinning process and ensuring that the spun fibers have good spinnability and post-processing property. Acetate fibers are short for cellulose acetate fibers, and are the earliest organic acid esters of cellulose in cellulose derivatives that have been commercially produced. The acetate fiber is prepared through solution spinning process, esterifying with acetic acid as solvent and acetic anhydride as acetylating agent in the presence of catalyst to produce cellulose acetate, and spinning. Because the acetate fiber contains a large amount of carboxyl and hydroxyl in the molecular structure, strong intermolecular entanglement is formed, and the processing difficulty is greatly increased.
The filter stick for cigarettes on the market is mainly made of acetate fiber tows. In the industrial production process of filter stick acetate fiber tows for cigarettes, the microbial content of mineral oil adopted in spinning is too high due to long-term operation of equipment, so that the phenomenon of growing microbial Legionella exists. In the industry, the aim of bacteriostasis is achieved by adding hydrogen peroxide, but the following problems are found in practice: (1) The bacteriostasis effect is not ideal, the phenomenon of microorganism growth is always caused, and the oil groove needs to be cleaned manually, so that time and labor are wasted; (2) Residual hydrogen peroxide in the acetate fiber tows can lead to the fracture of the acetate fibers at high temperature to form fly on the one hand, so that the quality of the acetate fiber tows is affected, and on the other hand, the residual hydrogen peroxide is unfavorable for storage due to the influence on the physicochemical property index of the tows. In addition, in order to be suitable for the cigarette filter stick, the spinning oil should be colorless, odorless and nontoxic, and cannot influence the flavor of the cigarette.
There are also documents that do not use hydrogen peroxide to achieve antibacterial effect, for example CN102021824B discloses a bacteriostatic agent emulsifier for spinning oil capable of inhibiting microorganism growth, which specifically comprises 92.7-99.6% of emulsifier, 0.2-0.5% of sodium benzoate, 0.2-3.0% of nepal gold ester, 0-1.0% of dimethyl fumarate, 0-3.7% of calcium propionate, 0-1.5% of pear, and 0-0.3% of dehydroacetic acid. However, the technical proposal of the emulsifier is disclosed in the document, the emulsifier is only one of the components for manufacturing the oiling agent, and can not be directly used for spinning; the addition of such a plurality of antimicrobial agents to the emulsifier can affect the emulsifying properties of the emulsifier, adversely affecting the formulated oil; these antimicrobial agents are all water-soluble compounds, which are added directly to the mixture of pure span 20, tween 80, and do not dissolve completely. Therefore, the technical solution disclosed in this document does not meet the actual operating needs of mass production.
Therefore, there is an urgent need to find a spinning oil which can be applied to mass production, has antibacterial effect and is suitable for acetate fibers for cigarette filter sticks.
Disclosure of Invention
In order to overcome the technical problems, the invention aims to provide the antibacterial spinning oil which has simple components, is convenient to operate, can be directly applied without subsequent compounding and is suitable for acetate fibers for cigarette filter sticks.
The invention provides an antibacterial spinning oil suitable for acetate fibers for cigarette filter sticks, which comprises an emulsifier, a mineral agent, a fat-soluble antibacterial agent and water or water containing the water-soluble antibacterial agent, wherein the spinning oil is transparent water-in-oil liquid before phase inversion, is oil-in-water emulsion after phase inversion, is carried out in water or water containing the water-soluble antibacterial agent, and has the mass ratio of (1-49) to the water containing the water-soluble antibacterial agent before phase inversion: (99-51).
Preferably, in the antibacterial spinning oil suitable for acetate fibers for cigarette filter sticks provided by the invention, the mass ratio of the spinning oil before phase inversion to the water for phase inversion or the water containing water-soluble antibacterial agent is (1-20): (99-80).
Preferably, in the antibacterial spinning oil suitable for acetate fibers for cigarette filter sticks provided by the invention, the fat-soluble antibacterial agent is one or more of benzoic acid, sorbic acid, ethyl parahydroxybenzoate and propyl parahydroxybenzoate, and the mass ratio of the fat-soluble antibacterial agent to mineral oil before phase inversion is (0.1-100): (99.9-0).
Preferably, in the antibacterial spinning oil suitable for acetate fibers for cigarette filter sticks, the ratio of the emulsifier before phase inversion in the spinning oil before phase inversion is 18-60 wt%, the total ratio of the fat-soluble antibacterial agent before phase inversion and the mineral oil before phase inversion in the spinning oil before phase inversion is 30-80 wt%, and the ratio of the water before phase inversion or the water containing the water-soluble antibacterial agent in the spinning oil before phase inversion is 3-20 wt%.
Still preferably, in the antibacterial spinning oil suitable for acetate fibers for cigarette filter sticks provided by the invention, the ratio of the emulsifier before phase inversion in the spinning oil before phase inversion is 20-50 wt%, the ratio of the fat-soluble antibacterial agent before phase inversion and the mineral oil before phase inversion in the spinning oil before phase inversion is 40-80 wt%, and the ratio of the water before phase inversion or the water containing the water-soluble antibacterial agent in the spinning oil before phase inversion is 3-15 wt%.
