Preparation method of self-fragrance natural antibacterial and deodorizing fiber and application thereof

Abstract

The invention relates to a preparation method of self-fragrance natural antibacterial and deodorizing fiber. The preparation method comprises the following steps of (1) preparing a fragrance slow release body; (2) preparing a natural antibacterial composition; (3) preparing fragrance natural antibacterial and deodorizing master batches; (4) preparing self-fragrance natural deodorizing fiber, wherein the prepared self-fragrance natural antibacterial and deodorizing fiber is of a skin-core structure including a core layer and a skin layer; the core layer is a high-melting-point polymer; the skin layer is a low-melting-point polymer; a high-molting point polymer body of the core layer comprises the fragrance slow-release bodies and the natural antibacterial compositions. The fiber provided by the invention has no irritation on the human body skin, has the permanent antibacterial performance, can inhibit the bacterium invasion and breeding, and has high absorption rate on ammonia and very excellent antibacterial mouldproof and deodorization effects; the characteristics of uniform fragrance release and long fragrance maintaining time are realized; the product added value is high; the application market prospects are wide.

Description

Technical field

[0001] The invention relates to the field of functional synthetic fibers, in particular to a preparation method and application of self-aromatic natural antibacterial and deodorizing fibers. Background technique

[0002] With the improvement of people’s living standards, in addition to the added value of products such as packaging, smell, color, shape, etc., people are more and more concerned about the health of themselves and their family members, and they are more and more concerned about the use of fiber woven or non-woven products in daily life. It is easy to breed bacteria in the potential danger, so it is necessary to provide a natural antibacterial fiber and its products with fragrance. Different fragrances will have different feelings on the human body and have the characteristics of physical therapy, insect repellent and antibacterial. For example, natural cypress It is effective in assisting human sleep and repelling mites. Eucalyptus essential oil has a...

Embodiment 1

[0045] In this embodiment, the preparation of self-aromatic natural antibacterial and deodorizing fibers includes the preparation of aromatic sustained-release bodies, the preparation of natural antibacterial and deodorizing compositions, the preparation of self-aromatic natural antibacterial and deodorizing masterbatch, and the preparation of self-aromatic natural antibacterial and deodorizing fibers. The specific preparation process and steps are as follows:

[0046] 1) Preparation of aromatic sustained-release body: In this process, the aromatic sustained-release body adopts spray drying microcapsule technology, the polymer of the capsule wall adopts gum arabic, and the fragrance type of the aromatic essential oil in the capsule core chooses jasmine essential oil, which is calculated according to the mass percentage. , Arabic gum: Jasmine essential oil is 40%:60%, the emulsifier is Span-80, and its mass accounts for 0.5% of the jasmine essential oil. The preparation process inc...

Embodiment 2

[0067] In this embodiment, the specific preparation process and steps of the self-aromatic natural antibacterial and deodorizing fiber are as follows:

[0068] 1) Preparation of aromatic sustained-release body: In this process, the aromatic sustained-release body adopts spray drying microcapsule technology, the wall polymer adopts urea-formaldehyde resin prepolymer, and the fragrance type of the aromatic essential oil in the capsule core chooses lemon essential oil. According to the calculation, the ratio of ethylene-vinyl acetate copolymer: lemon essential oil is 60%:40%, the emulsifier is sodium dodecylbenzene sulfonate, and its mass proportion is 0.8% of the lemon essential oil. The preparation process includes the following step:

[0069] Step 1: Weigh 40 parts of lemon essential oil, add the emulsifier sodium dodecylbenzene sulfonate to the essential oil, stir to dissolve and form an oil phase.

[0070] Step 2: Weigh a solution of 60 parts of urea-formaldehyde resin prepolymer ...

Embodiment 3

[0090] This example is a comparative example, that is, this example does not add aromatic sustained-release body and natural antibacterial composition, but uses polyethylene terephthalate and polyethylene to directly melt extrude and spin to obtain the core The structure of the bicomponent fiber, specifically, the fiber preparation process of this embodiment is the same as that of embodiment 2, that is, it includes the following steps:

[0091] Step 1: Take 30 parts of polyethylene and set its spinning temperature to 190-220°C.

[0092] Step 2: Take 100 parts of polyethylene terephthalate into the screw extruder, and enter the compound spinning box through the twin-screw extruder.

[0093] Step 3: Set the spinning temperature to 280°C, set the spinning temperature to 285-295°C, the spinning winding speed to 950-120m / min, the cooling air temperature to 16-20°C, and the wind speed to 4-6m / s , The screw length to diameter ratio L / D is 20-28, and the compression ratio is 3.5-3.7.
