Description
Technical field
The invention belongs to the weaving production technical field, be specifically related to the antibiotic of a kind of COTTON FABRIC and wrinkle proofing method.
Background technology
COTTON FABRIC enjoys people to favor because it has the multiple good wearability such as softness, comfortable, ventilative, good hygroscopicity.But COTTON FABRIC has inferior resistance to microorganism, can adsorb the hot humid medium that human body distributes when wearing, and for the breeding of microorganism provides good environment, thereby causes fabric to produce bad smell, even discolour, and mechanical strength reduces; In addition, COTTON FABRIC is subjected to External Force Acting in wearing process, relative displacement can occur in cellulose molecular chain or its fundamental structural unit, and original hydrogen bond is opened, and generates new hydrogen bond, after external force is eliminated, creep can occur, excessive in external force, in the action time long situation, permanent sex change and wrinkle just appear, the aesthetic property of impact dress.Therefore, COTTON FABRIC being carried out antibiotic and crease resistant functions arrangement is very important.
At present, prior art adopts traditional N-methylol amide resinoid as crease proofing agent usually, although the durable anti-wrinkle effect of this finishing agent is good, but the shortcomings such as the fabric of wherethrough reason exists, and strength loss is serious, yellowing and burst size of methanal are large, and deposit with wearing process in, also harmful formaldehyde be can constantly discharge, human skin and respiratory mucosa stimulated, in addition carcinogenic.Along with growth in the living standard, people more pay attention to the functional of clothes, only no longer possess competitive advantage through single textiles antibiotic or the crease resistant functions arrangement.Patent 200510123828 discloses a kind of wrinkle proofing method of color cotton fabric, adopts N-methylol amide resinoid as crease proofing agent; Although patent 200610119085 and patent 200810184879 adopt polybasic carboxylic acid class formaldehydeless finishing agent, only limit to single wrinkle proofing; Patent 00117001 discloses a kind of production method of antibiotic, crease resistant fabric, but the fabric of being processed by this method can discharge free formaldehyde; The 7th page to the 9th page of Shandong Textile science and technology the 5th phase of calendar year 2001 discloses a kind of polybasic carboxylic acid (citric acid and tartaric acid) and shitosan to the wrinkle resistant and antibiotic finish of COTTON FABRIC, but process COTTON FABRIC with shitosan as antiseptic, can affect Fabric Style, make the fabric face feel coarse, and this patent is not announced its anti-microbial property test effect data.
Summary of the invention
The defects that the applicant exists for Cotton Fabric method in the prior art, a kind of Anti-bacterial and Crease method of COTTON FABRIC is provided, and the COTTON FABRIC of putting in order by the method possesses antibiotic and wrinkle resistant dual property simultaneously, and antimicrobial efficiency is high, crease resistance is good, and formaldehydeless release.
Technical scheme of the present invention is as follows:
A kind of Anti-bacterial and Crease method of COTTON FABRIC, first with catalyst, equimolar 2,2,6,6-tetramethyl-4-piperidine alcohols and BTCA composition arrangement soluble in water body lotion, and COTTON FABRIC be impregnated in the described arrangement body lotion; Then through padding, preliminary drying and bake operation described COTTON FABRIC is processed, at last to soap through the described COTTON FABRIC that bakes processing, wash, oven dry, halogenation, again oven dry; Described catalyst is a kind of in sodium dihydrogen phosphate, sodium hydrogen phosphate, sodium polyphosphate, the sodium hypophosphite, and described halogenation treatment will be for impregnated in through the COTTON FABRIC of described drying and processing in sodium chlorate, calcium hypochlorite or the sodium hypobromite solution.
Its further technical scheme is:
In described arrangement body lotion, the mass percentage concentration of described catalyst is 0～10%.
In described arrangement body lotion, described 2,2,6, the mass percentage concentration of 6-tetramethyl-4-piperidine alcohols is 1～10%.
The described temperature that bakes processing is 150～200 ℃, and the time is 30～300s.
Described clorox, calcium hypochlorite, sodium hypobromite solution quality percentage concentration are respectively 0.01～1%.
Useful technique effect of the present invention is:
The present invention is first with catalyst, equimolar 2,2,6,6-tetramethyl-4-piperidine alcohols and BTCA composition arrangement soluble in water body lotion, and COTTON FABRIC be impregnated in the described arrangement body lotion; BTCA (BTCA) is in curing treatment process, dehydration forms cyclic acid anhydride under high temperature (150～200 ℃) condition, and further with 2,2, hydroxyl generation esterification on 6,6-tetramethyl-4-piperidine alcohols (TMP) and the large molecule of COTTON FABRIC fiber forms covalent cross-linking; In the halogenation operation, in 2,2,6 of the above-mentioned cross-linking reaction of process, the upper oxidisability halogen atom of introducing of 6-tetramethyl-4-piperidine alcohols (TMP) generates a kind of halogen amines with antibacterial functions at last.In addition and since BTCA (BTCA) this as a kind of good formaldehyde-free crease-proofing finishing agent, thereby make the COTTON FABRIC through arrangement possess simultaneously antibiotic and wrinkle resistant dual property, antimicrobial efficiency height, crease resistance is good, and formaldehydeless release.Anti-microbial property and crease recovery test show, the COTTON FABRIC of putting in order by the inventive method is with after inoculated bacteria contacts, sterilizing rate to staphylococcus aureus in 5min reaches 100%, in 10min to Escherichia coli O 157: the sterilizing rate of H7 reaches 83.25%, compare and be significantly increased before creasy recovery angle and the arrangement, be elevated to 251.6 by 111.7.
