Background
Pure cotton fabric has good wear performance, is green and natural, and is an important textile clothing fabric all the time. However, pure cotton fabrics are easy to crease in the process of taking or washing, so that crease-resistant finishing agents are industrially adopted to carry out crease-resistant finishing on the pure cotton fabrics to improve crease-resistant performance of the fabrics. The crease-resistant finishing agent used at present is mainly a finishing agent containing resin with an N-methylolamide structure (or etherified modification thereof) and part of polycarboxylic acid. The N-methylol amide crease-resistant finishing agent is produced by taking formaldehyde as a raw material, and formaldehyde is released in the production process, the crease-resistant finishing process of fabrics and the taking process of crease-resistant finishing fabrics, namely the so-called formaldehyde problem.
Many pathogenic microorganisms exist in the environment, which seriously affect the healthy life of people. The porous structure of the textile is extremely easy to adsorb and grow bacteria, and harmful bacteria take the textile as a medium to endanger the health of human beings. With the improvement of health awareness and environmental protection awareness, the research and development of antibacterial materials, particularly antibacterial textiles, are receiving a great deal of attention. The quaternary ammonium salt has the characteristics of broad-spectrum antibacterial property, difficult diffusion, low bacterial resistance and the like, and is one of the most widely applied antibacterial substances at present. However, the water-soluble fiber has a problem of poor durability because of its strong water-solubility and poor bonding strength with fibers.

The preparation method is simple in preparation process, the finished cotton fabric not only realizes excellent crease-resistant and antibacterial properties, but also is uniformly crosslinked, and the cotton fabric is endowed with higher tensile strength, washing resistance and skin smoothness; meanwhile, formaldehyde is not involved in the whole finishing process, so that the problem of formaldehyde residue is eliminated from the source.
The invention is realized by the following technical scheme:
an anti-wrinkle and antibacterial finishing method for cotton fabric based on organic silicon resin comprises the following steps:
s1: dissolving ethylamino diethyl mercaptan and bromopropane in an ethanol solution, and carrying out heating reflux reaction under magnetic stirring to prepare dimercapto-functionalized quaternary ammonium salt; dissolving the obtained dimercapto-functionalized quaternary ammonium salt in N, N-dimethylformamide, adding a catalyst DMPA and vinyl-functionalized organosiloxane, and carrying out catalytic reaction to obtain a quaternary ammonium salt-functionalized double-headed siloxane precursor;

。

、/>、/>。
further, the photobase initiator in S2 is one or more than two of 9-anthracene methyl piperidine-1-carboxylic acid tert-butyl ester, 9-anthracene methyl ester N, N-diethyl carbamate, (E) -N-cyclohexyl-3- (2-hydroxyphenyl) acrylamide or (2-nitryl phenyl) methyl-4-hydroxy piperidine-1-carboxylic acid tert-butyl ester.
Further, in the S1, the mol ratio of the ethylamino diethyl mercaptan to the bromopropane is 1:1-1.2, and the mol ratio of the dimercapto-functionalized quaternary ammonium salt, the vinyl-functionalized organosiloxane and the catalyst DMPA is 1:2-2.2:0.01-0.05.
Further, the mass ratio of the quaternary ammonium salt functionalized double-headed siloxane precursor, the photobase and the solvent acetone in the S2 is 1:0.01-0.05:10.
Further, the time of the heating reflux reaction in S1 is 20-24h, and the catalytic reaction is carried out by irradiation under 365nm ultraviolet light for 1-2h.
Further, S2 at 254 nm, 365nm or 395nm under ultraviolet light, the illumination intensity being 20 mw/cm 2 The time is 1-2h.
And further, after the heating reflux reaction in the step S1 is finished, removing ethanol by rotary evaporation to obtain a crude product, recrystallizing the crude product in ethanol, and drying in vacuum at normal temperature to obtain the dimercapto-functionalized quaternary ammonium salt.
Compared with the prior art, the invention has the beneficial effects that:
the quaternary ammonium salt functionalized double-headed siloxane precursor is synthesized, and is used as an anti-wrinkle antibacterial finishing agent for the anti-wrinkle antibacterial finishing of cotton fabrics through a photoinduction sol-gel process. The cotton fabric finished by the method not only realizes excellent crease-resistant and antibacterial properties, but also is uniformly crosslinked, and is endowed with higher tensile strength, washing resistance and skin smoothness; meanwhile, formaldehyde is not involved in the whole finishing process, so that the problem of formaldehyde residue is eliminated from the source, and the method is specifically shown as follows:
(1) Under ultraviolet irradiation, the photoinduced alkali is decomposed to release Lewis base, the siloxane precursor is catalyzed to be hydrolyzed to form Si-OH, and the Si-OH can be uniformly and efficiently crosslinked with hydroxyl groups on cellulose fibers in an unfixed area to inhibit irreversible relative sliding of molecular chains under the action of external force, so that the anti-wrinkle performance is excellent.
(2) The photoinduced base catalyzed crosslinking process at room temperature does not induce acidic degradation of macromolecular chains of cotton cellulose caused by conventional high-temperature baking, so that the cotton fabric with high strength retention rate is prepared.
(3) The introduced quaternary ammonium salt is formed by covalent bonds, so that the loss of the quaternary ammonium salt functional group in the water washing process can be effectively avoided while the broad-spectrum antibacterial performance is ensured, and the finished cotton fabric still has excellent crease resistance and antibacterial performance after washing for many times.
