Embodiment 1

[0026] The composite non-woven fabric is composed of an antibacterial layer, a flame-retardant layer, and a needle-punched non-woven fabric layer, wherein the flame-retardant layer is prepared by the following method:

[0027] A. With 10 parts of urea, 5 parts of melamine, 30 parts of formaldehyde and 60 parts of deionized water, add 5 parts of triethanolamine to obtain a preliminary solution;

[0028] B. Mix 15 parts of ammonium phosphate, 70 parts of deionized water, and 0.1 part of Tween-80 surfactant evenly, then stir on a homogeneous mixer at a high speed of about 1000 rpm, emulsify and disperse for 10 minutes, then add 30 parts of distilled water, Adjust the speed to about 2000rpm, homogenize and disperse for 20 minutes to obtain a stable emulsion, then add 0.1 part of maleic anhydride graft compatibilizer, 0.1 part of Tween-80 surfactant, adjust the pH value to 6 with tartaric acid solution, add dropwise One-fifth of the preparatory solution was obtained in step A. Afte...

Embodiment 2

[0044] The composite non-woven fabric is formed from an antibacterial layer, a flame-retardant layer, and a needle-punched non-woven fabric layer, wherein the flame-retardant layer is prepared by the following method:

[0045] A. With 11 parts of urea, 6 parts of melamine, 28 parts of formaldehyde and 55 parts of deionized water, add 3 parts of triethanolamine to obtain a preliminary solution;

[0046] B. Mix 14 parts of ammonium phosphate, 13 parts of ammonium phosphate, 75 parts of deionized water, and 0.1 part of Tween-80 surfactant evenly, then stir on a homogeneous mixer at a high speed of about 1000 rpm, and emulsify and disperse for 10 minutes. Then add 23 parts of distilled water, adjust the speed to about 2000rpm, homogenize and disperse for 20 minutes to obtain a stable emulsion, then add 0.1 part of maleic anhydride graft compatibilizer, 0.1 part of Tween-80 surfactant, adjust the pH with tartaric acid solution value to 6, drop one-fifth of the preparation solution ...

Embodiment 3

[0063] The composite non-woven fabric is composed of an antibacterial layer, a flame-retardant layer, and a needle-punched non-woven fabric layer, wherein the flame-retardant layer is prepared by the following method:

[0064] A. With 12 parts of urea, 7 parts of melamine, 25 parts of formaldehyde and 50 parts of deionized water, add 1 part of triethanolamine to obtain a preliminary solution;

[0065] B. Mix 10 parts of ammonium phosphate, 80 parts of deionized water, and 0.1 part of Tween-80 surfactant evenly, then stir on a homogeneous mixer at a high speed of about 1000 rpm, emulsify and disperse for 10 minutes, then add 15 parts of distilled water, Adjust the speed to about 2000rpm, homogenize and disperse for 20 minutes to obtain a stable emulsion, then add 0.2 parts of maleic anhydride graft compatibilizer, 0.1 part of Tween-80 surfactant, adjust the pH value to 6 with tartaric acid solution, add dropwise One-fifth of the preparatory solution was obtained in step A.

Abstract

The invention discloses an antibacterial flame-retardant needle-punched compound nonwoven fabric preparation method. An antibacterial flame-retardant needle-punched compound nonwoven fabric has advantages of high structural strength and texture compactness, environmental friendliness, safety, reliability, convenience in manufacturing, wide application range and the like and provides a cottony comfortable handfeel. Antibacterial microcapsules are uniformly distributed in an antibacterial layer, excellent broad-spectrum, slow-release and bactericidal effects are achieved, drug tolerance and toxicity are avoided, and antibacterial and bacteriostatic effects are effectively achieved due to adding of nano zinc oxide and chitosan. Owing to adding of essence aromatic substances, the microcapsulescontinuously emit aroma in a utilization process to mask odors, and a high popularization and application value is achieved. The practice proves that the antibacterial effect is still kept even the fabric is washed for multiple times, and the antibacterial nonwoven material is promising in prospect.

Description

technical field [0001] The invention relates to a flame-retardant material, in particular to a method for preparing an antibacterial, flame-retardant and needle-punched composite non-woven fabric. Background technique [0002] As my country pays more and more attention to the field of fire and flame retardant, domestic research on flame retardant microencapsulation has also developed rapidly. Non-woven fabric is a widely used fabric, which has various types, such as spun-bonded non-woven fabric, melt-blown non-woven fabric, stitch-bonded non-woven fabric, needle-punched non-woven fabric, etc. Non-woven fabric is particularly flammable, When a fire breaks out, it cannot play a very good protective role. At the same time, once a fire breaks out, its burning speed is very fast, so special attention is paid to fire prevention and explosion protection in the textile industry. In addition, medical non-woven fabrics have the characteristics of high filterability to bacteria and du...
