Problems solved by technology

However, polyester fabrics have poor hygroscopicity and are prone to static electricity, making the fibers easily stained during subsequent processing and wearing, and static electricity will also reduce the wearing comfort of clothing
[0003] Regarding the antistatic finishing of polyester fabrics, there are currently two main solutions at home and abroad: one is to add antistatic surfactants or polymer permanent antistatic agents before melt spinning to obtain antistatic fibers. The process can easily change other excellent properties of the fiber; the second is to coat the surface of the fiber with an antistatic finishing agent. This process generally uses rolling, baking, and baking processes, which is relatively simple and easy, but with the continuous progress of society, The environmental protection requirements for dyeing and finishing auxiliaries are getting higher and higher. Only dyeing and finishing auxiliaries that meet environmental protection requirements can meet the development requirements of ecological textiles

preparation example Construction

[0022] The preparation process of step 10) is: adding chitosan to the container, and then adding a 99.7% isopropanol solution, wherein the mass ratio of the chitosan to the isopropanol solution is 1:8-16, While stirring the chitosan and isopropanol solutions, add a 40% mass fraction of NaOH solution. The mass ratio of chitosan to NaOH solution is 1:1 to 6 to form a mixed solution. Stir the mixed solution at 44°C. After the chitosan is melted for 2 to 4 hours, a 50% mass fraction of chloroacetic acid aqueous solution is dropped in 20min to 1.5h, and the mass ratio of chitosan to chloroacetic acid aqueous solution is 1:1 to 5; after dropping the chloroacetic acid aqueous solution , Reacting at 50-65°C for 4-10h to prepare N,O-carboxymethyl chitosan solution with a degree of substitution of 40-150%. If the amino group at position 2 and the hydroxyl group at position 6 in the chitosan molecular structure are all substituted, the degree of substitution should be 200%. Although theo...

[0031] A finishing method of polyester fabric, the polyester fabric is made of polyester, including the following steps:

[0032] Step 10): Prepare N,O-carboxymethyl chitosan solution: add chitosan with a molecular weight of 100000 Da into the container, and then add a 99.7% isopropanol solution, where chitosan and isopropyl The mass ratio of the alcohol solution is 1:8. While stirring the chitosan and isopropanol solutions, add a 40% mass fraction of NaOH solution. The mass ratio of chitosan and NaOH solution is 1:1 to form a mixed solution. Stir the mixed solution at 44℃. After alkalizing the chitosan for 2 hours, drop a 50% mass fraction of chloroacetic acid aqueous solution within 20 minutes. The mass ratio of chitosan to the chloroacetic acid aqueous solution is 1:1; finish dropping the chloroacetic acid aqueous solution Then, the reaction was carried out at 50° C. for 4 hours to obtain a N,O-carboxymethyl chitosan solution with a degree of substitution of 90%.

Abstract

The invention discloses a method for finishing an antistatic antibacterial and hydrophilic polyester fabric. The finishing method comprises the following steps: step (10) preparing an N,O-carboxymethyl chitosan solution; step (20) performing pretreatment on the polyester fabric by adopting cold plasma; and step (30) dipping the polyester fabric treated in the step (20) by utilizing a polyethyleneimine solution, then dipping the polyester fabric by utilizing a glutaraldehyde solution, and finally, dipping the polyester fabric by utilizing the N,O-carboxymethyl chitosan solution prepared in the step (10), thereby obtaining the treated polyester fabric. According to the finishing method, the polyester fabric has good antistatic antibacterial and hydrophilic performances.

Description

Technical field [0001] The invention belongs to a finishing method of textile materials, and specifically relates to a finishing method of polyester fabric with antistatic, antibacterial and hydrophilic properties. Background technique [0002] Polyester is a synthetic fiber with good elasticity, dimensional stability and blending properties. However, polyester fabric has poor hygroscopicity and is easy to be charged with static electricity, which makes the fiber easy to be contaminated during subsequent processing and taking. At the same time, static electricity will reduce the wearing comfort of clothing. [0003] Regarding the antistatic finishing of polyester fabrics, there are currently two main solutions at home and abroad: one is to add antistatic surfactants or polymer permanent antistatic agents before melt spinning to obtain antistatic fibers, but this The process can easily change the other excellent properties of the fiber; the second is to coat the surface of the fibe...
