Problems solved by technology

Clothing has exceeded the requirements of keeping warm and covering the body, and at the same time must meet the requirements of environmental protection and health care. Natural fibers have good hygroscopicity, and the fabrics made of them have excellent wearability. However, due to the limitations of planting and geographical conditions, the output has not meet needs

Embodiment 1

[0010] 1) Measure 1000 parts by weight of fresh pure milk with a measuring cylinder, place it in an evaporator at 60-70°C, 70kPa-80kPa for 12 hours under reduced pressure and evaporate it, then take it out and place it in a conical flask, and place the conical flask in a centrifuge In the process, the speed of the centrifuge is set at 1000r / min to 2000r / min, and after centrifugation for 4 hours, 180 parts by weight of NaOH aqueous solution is added, the molar ratio of alkali to water in the lye is 1:20 to 1:25, and the pH is adjusted to 7.3; use 1nm The semi-permeable membrane separates the protein in the emulsion after the alkalization reaction, adds 50 parts by weight of NaCl solution with a mass fraction of 3%, and collects the separated protein in the Erlenmeyer flask for subsequent use;

[0011] 2) Add 100 parts by weight of deionized water and 56.7 parts by weight of selenium nanomaterials into the Erlenmeyer flask, send them into the shaker for 12 hours at a speed of 100...

Embodiment 2

[0015] It is exactly the same as Example 1, except that 170 parts by weight of NaOH aqueous solution, 57.7 parts by weight of selenium nanomaterials, and 1.88 parts by weight of PBST / ZSM-35 nanocomposite materials are added.

Embodiment 3

[0017] It is exactly the same as Example 1, except that 160 parts by weight of NaOH aqueous solution, 58.7 parts by weight of selenium nanomaterials, and 1.98 parts by weight of PBST / ZSM-35 nanocomposite materials are added.

Abstract

The invention discloses a preparation method of novel special modified milk protein fibers for infants. The preparation method comprises the main steps as follows: taking pure milk as a main raw material and removing surplus water through evaporation; after concentrating the milk until the water content is 60 percent or less, adding alkali and decomposing fat; separating through a dialysis methodto obtain high-molecular-weight protein which cannot penetrate through a semipermeable membrane; taking the extracted protein as a material for preparing the milk protein fibers; adding a selenium nano material and a PBST / ZSM-35 nano composite material to improve the stability of the milk protein fibers. The milk protein fibers prepared by the preparation method have a natural antibacterial effectand any allergic reaction on skin is not caused. Components including the protein and the like in the milk protein fibers are necessary for human bodies and have a relatively good protection effect on the skin of the human bodies; when the milk protein fibers get close to the surface of the skin of the human body, a smooth and air-permeable feeling is provided.

Description

technical field [0001] The invention relates to a novel material, in particular to a special modified milk protein fiber for infants. Background technique [0002] With the continuous improvement of living standards, people have more and more stringent requirements on the performance of clothing fibers, especially for baby and children's clothing. Clothing has exceeded the requirements of keeping warm and covering the body, and at the same time must meet the requirements of environmental protection and health care. Natural fibers have good hygroscopicity, and the fabrics made of them have excellent wearability. However, due to the limitations of planting and geographical conditions, the output has not Meet the needs. [0003] In recent years, especially in the 21st century, people's calls for "environmental protection" have been increasing day by day. Regenerated protein fibers have attracted more and more attention because of their excellent application performance. Milk ...
