Fabric antioxidant with seaweed extract and method for preparing fabric antioxidant

Abstract

The invention provides a fabric antioxidant containing seaweed extract and a preparation method thereof. The specific operation steps are as follows: (1) wash the chlorella surface attachments and sand grains with filtered seawater, and dry it at room temperature. Place in an oven to dry to remove excess moisture, remove, chop and grind to form chlorella powder; (2) place the chlorella powder prepared in step (1) in a mixed solvent of methanol and chloroform, reflux extraction twice, and combine the filtrates , the filtrate is evaporated to form a chlorella extract; (3) the chlorella extract prepared in step (2) is placed in a supercritical carbon dioxide extraction device, and extracted to obtain a chlorella extract; (4) the step (3) ) to the chlorella extract prepared by adding additives, heating and stirring evenly, rinsing and filtering, and naturally cooling to room temperature to obtain the fabric antioxidant containing seaweed extract. The fabric antioxidant containing the seaweed extract prepared by the invention has very strong antioxidant activity and low side effects, and expands the application range of the seaweed.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, and in particular relates to a fabric antioxidant containing seaweed extract and a preparation method thereof. Background technique: [0002] Ultraviolet rays are electromagnetic waves with a shorter wavelength than visible light. Different wavelengths of ultraviolet rays have different degrees of harm to the human body. People will be affected by ultraviolet rays to varying degrees in daily life and industrial production. At present, in the textile field, the application of antioxidants in fabric finishing and daily care has been relatively common. In the post-finishing process of fabrics, in order to make the width, grammage and flatness of the fabric meet the requirements of the finished product, it is necessary to set the fabric under high temperature conditions, and too high a setting temperature will cause the fibers in the fabric to be oxidized and Yellowing and brittleness wil...

Problems solved by technology

[0003] Antioxidants are substances that can delay the deterioration, rancidity or discoloration of hard gas due to oxidation. Chemically synthesized antioxidants are often used at home and abroad, such as dibutyl hydroxytoluene, butyl hydroxyanisole, propyl gallate and tert-butyl Hydroquinone, etc., can replenish and neutralize free radicals, thereby eliminating the damage of free radicals to substances, or can effectively prevent or delay the automatic oxidation process of substances, but these chemically synthesized antioxidants have certain toxicity and carcinogenic effects , is that people have doubts and rejection of synthetic antioxidants
