As used herein, the terms "substantially", "substantially", and the like are used herein to refer to a value in or near the numerical value when presenting manufacturing and material tolerances inherent in the meanings mentioned, Absolute numbers are used to prevent unauthorized exploitation by unauthorized intruders of the mentioned disclosure.
The present invention relates to a biodegradable fiber having deodorant properties, wherein 90 to 99% by weight of a cellulose mixed composition and 1 to 10% by weight of a deodorant are mixed to form deodorized biodegradable fibers.
The cellulose mixed composition is composed of a thermoplastic cellulose fatty acid mixed ester and a plasticizer, and the thermoplastic cellulose fatty acid mixed ester preferably has a number average molecular weight of 20,000 to 200,000.
The cellulose mixed composition of the present invention may be preferably used by mixing 70 to 99% by weight of the cellulose fatty acid mixed ester and 1 to 30% by weight of the plasticizer.
The cellulosic fatty acid mixed ester constituting the fiber comprising the cellulose mixed composition of the present invention means that three hydroxyl groups present in the cellulose glucose unit are blocked by two or more kinds of acyl groups. From the viewpoints of preparation workability and miscibility with cellulose acetate as a constituent of a different kind, the cellulose fatty acid mixed ester of the present invention is preferably selected from the group consisting of cellulose diacetate, cellulose acetate propionate, cellulose acetate butyrate, cellulose acetate propionate butyrate , Cellulose acetate hexanoate, cellulose acetate octanoate, cellulose acetate decanoate, and mixtures of two or more thereof. In the case of cellulose diacetate, the addition amount of an appropriate plasticizer during fibrosis may be controlled to maintain stability at a high temperature It is most preferable to use cellulose diacetate.
As the plasticizer constituting the fiber comprising the cellulose mixed composition of the present invention, it is preferable to use any one or a mixture of two or more of polyethylene glycol (PEG), triacetin, glycerin, epoxidized soybean oil and 1,4-dianhydrosorbitol diester , Biomass-based biomass-based 1,4-dianhydrosorbitol produced by the conversion of glucose and sorbitol through the hydrolysis of enzymes, and starch extracted from corn and wheat 1,4-dianhydrosorbitol diester compound or a soybean oil compound obtained by epoxidizing soybean oil extracted from soybean oil.
In particular, the plasticizer of the present invention has good compatibility with a cellulose fatty acid mixed ester, which is a constituent component of the thermoplastic cellulose ester composition, and exhibits a thermosetting effect capable of melt spinning.
