Embodiment 1

[0046] A non-woven fiber material used for medical and health protection, wherein the non-woven fiber material is modified polypropylene fiber.

[0047] The modified polypropylene fiber is obtained by modifying polypropylene with surface functional coral powder, and the mass ratio of surface functional coral powder to polypropylene is 1:20.

[0048] The diameter of the modified polypropylene fiber is 5-50 μm.

[0049] The preparation method of the surface functional coral powder is:

[0050] Step 1, firstly polish the coral sand into fine coral powder, then subject the fine coral powder to amination treatment to obtain coral powder amino treatment;

[0051] In step 2, the coral powder amino treatment substance is used to carry out grafting reaction with luteolin to obtain surface functional coral powder.

[0052] In the step 1, the coral sand is firstly ground to obtain 1-100 μm coral coarse powder, and then polished into 10-50 nm coral fine powder.

[0053] In the step 1, th...

Abstract

The invention relates to a non-woven fiber material for medical and health protection and its production process. The non-woven fiber material is a modified polypropylene fiber; the modified polypropylene fiber is made of surface-functional coral powder. Propylene modification is obtained, and the mass ratio of surface functional coral powder to polypropylene is 1:15 to 35; the preparation method of the surface functional coral powder is as follows: step 1, firstly, coral sand is polished into coral fine powder, and then The coral fine powder is subjected to amino treatment to obtain a coral powder amino-treated product; step 2, using the coral powder amino-treated product to perform grafting reaction with luteolin to obtain a surface-functional coral powder. The invention prepares and synthesizes a modified polypropylene fiber with strong hygroscopicity and antibacterial property by hydrophilically modifying the hydrophobic polypropylene fiber.

Description

technical field [0001] The invention relates to the field of medical protection, in particular to a non-woven fiber material for medical and health protection and a production process thereof. Background technique [0002] Non-woven fabrics have excellent air permeability, softness and hygienic properties, and have been widely used to make medical and sanitary products. Medical and sanitary products made of non-woven fabrics include protective surgical gowns, protective clothing, patient clothing, sterile dressing cloth and various wet wipes, protective sanitary masks, medical sheets, curtains, etc., as well as external correction bandages , Surgical use of various surgical towels and so on. Most of the raw materials for making non-woven fabrics are polypropylene, which is different from polyethylene, the raw material of plastic bags. The chemical molecular structure is quite stable and extremely difficult to degrade, so plastic bags need 300 years to completely decompose, ...
