Problems solved by technology

Although the medical fabrics in the above patents have certain special functions, such as: antibacterial, liquid-proof, moisture absorption, odor absorption, etc., the working environment of medical staff is more complicated, such as: radiation, static electricity, and highly infectious bacteria and viruses etc. Therefore, there is an urgent need to improve the existing medical fabrics to provide a medical fabric with good antibacterial effect, strong breathability and moisture absorption, no pilling, no lint, no fading, and certain radiation protection and antistatic effects, so as to improve medical care. Work comfort and safety of personnel

Embodiment 1

[0027] The preparation of embodiment 1 modified medical polyester

[0028] Raw material composition: 100 parts of surface-grafted polyester fiber, 10 parts of nickel-coated carbon fiber carbon black, 20 parts of cinnamon essential oil coated with β-cyclodextrin, 10 parts of micron-sized copper oxide, and 1 part of glyceryl tristearate;

[0029] Surface-grafted polyester fibers were prepared by the following method: weigh 100g of PET fibers, soak them in m-cresol at 40°C for 2h, wash with water and air-dry, and mix with 10mL 2mol / LK 2 CrO 4 Put the solution together in a conical flask, blow in nitrogen, and soak at constant temperature for 30min; then add 4mL 0.5mol / LH 2 SO 4 The solution and 5g of acrylamide were reacted at 70°C for 2 hours to obtain grafted fibers. The grafted fibers were soaked in deionized water, boiled at 100°C for 4 hours, taken out, and dried to obtain surface-grafted polyester fibers.

Abstract

The invention provides modified medical polyester fiber. The modified medical polyester fiber is prepared from, by weight, 100-150 parts of surface grafted polyester fiber, 10-20 parts of superconducting material, 20-40 parts of plant essential oil coated with beta-cyclodextrin, 10-25 parts of antiradiation additive and 1-5 parts of dispersant. The modified medical polyester fiber prepared by themethod has high flexibility, air permeability and high hygroscopicity, is free of pilling and fluffiness and has good color protection effect; the plant essential oil is added, so that the polyester fiber is bacteriostatic and aromatic; the superconducting material which is inorganic and the antiradiation additive which is organic are added, so that the polyester fiber has certain antistatic, antiradiation and anti-ultraviolet effects.

Description

technical field [0001] The invention relates to the technical field of textile fibers, in particular to a modified medical polyester and a preparation method thereof. Background technique [0002] Polyester, the scientific name of polyester fiber, is an important part of synthetic fibers in my country. It is made of purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) as raw materials through esterification or Polyethylene terephthalate (PET), a fiber-forming polymer that is worthwhile for transesterification and polycondensation reactions, is made into fibers after spinning and post-treatment. It has good mechanical strength, light resistance, and heat resistance. It is widely used in the medical field due to its excellent processability and easiness of spinning. [0003] Medical uniforms are a kind of special clothing designed for medical staff. Different from other professional uniforms, they face special groups and specific operating e...
