Background technology
Contain amino acid in 18 in protein fibre fibroin, form similar to human body skin structure, therefore silk fabric is often described as " Second Skin ", wears true silk products, allows people feel there is a kind of irreplaceable comfort.Because the fibrous fraction of its uniqueness, can health care be played to skin and therapeutic action be played to some dermatopathies.
But there is not chemical crosslinking between the protein macromolecule due to real silk, when silk fiber water suction swelling, sat linkage ruptures, and meanwhile, during hygrometric state, hydrone destroys the hydrogen bond between the large molecule of fiber, therefore when being subject to External Force Acting, strand is easy to Relative sliding occurs, and when external force is removed, intermolecular do not have again enough restraining forces to make it be returned to original position, this makes the real silk fabric wrinkle resistance that wets very poor, greatly have impact on the practical function of fabric.This is a critical defect of real silk fabric, brings inconvenience to the use of silk, is therefore necessary to carry out anti-crease finishing to real silk fabric.
Anti-crease finishing method for real silk in prior art is also on the books, as the domestic applications number patent of invention that is 2013103402577 discloses a kind of anti-crease finishing technique of silk fabric, relate to fabric Crease-Resist Finishing Technology field, this technique comprises the following steps: by each component preparation crease proofing agent of olefin acid quasi-oligomer, formic acid, catalyst, silicone softening agent and water; In bath raio 1:(25 ~ 30), at temperature 20 ~ 30 DEG C, silk fabric two leachings two in containing the dressing liquid of crease proofing agent are rolled, pick-up 85 ~ 90%, by the silk fabric preliminary drying 3 ~ 5min after padding, then at 140 ~ 150 DEG C, cure 1 ~ 2min, use the hot water wash of 40 ~ 50 DEG C successively, 20 ~ 25 DEG C of washings, dry at 70 ~ 80 DEG C and obtain the silk fabric after arranging.The crease-shedding finishing agent low in raw material price used in this technical scheme, not containing formaldehyde components, economic environmental protection, anti-crease finishing technique is simple to operation, and the silk fabric after arranging has good crease recovery energy and strength retention, and wrinkle resistance is good.But because it has the feel that silicone oil softener affects silk fabric, and affect its hydrophilicity.
Summary of the invention
The shortcoming of prior art in view of the above, the object of the present invention is to provide a kind of anti-crease finishing method of crease-shedding finishing agent and silk fabric, affects fabric feel and the not good problem of wrinkle resistance to overcome anti-crease finishing method in prior art.
In order to reach foregoing invention object and other objects, the present invention is achieved by the following technical solutions:
A kind of anti-crease finishing liquid, in the cumulative volume of described anti-crease finishing liquid for benchmark, described anti-crease finishing liquid comprises following raw material components and content:
Preferably, described soluble polyurethane is that model to be selected from Nano-PU and PU-new one or both.
Preferably, the number-average molecular weight of described shitosan is 1.6 × 10
4~ 1.7 × 10
4.
Preferably, described softener is selected from model is one or both in TEXILONESP and Hi-Soft40.
Preferably, described strong protecting agent is selected from one or both in FINETEXPES and PEP.
Preferably, described catalyst is selected from MgCl
2or one or both in sodium hypophosphite.
Preferably, the model of described bleeding agent is 230N.Described 230N is polyoxyethylene linear alkyl ether.
The invention also discloses a kind of anti-crease finishing method of silk fabric, for adopting as power anti-crease finishing liquid described above carries out padding finishing, then prebake successively, bake, wash water, oven dry and moisture regain.
More preferably, in the cumulative volume of cleaning solution for benchmark, the addition of described bleeding agent is 2 ~ 4g/L.
Preferably, two leachings two are adopted to roll in padding finishing operation.
Preferably, the pick-up in described padding finishing operation is 70 ~ 80wt%.
Preferably, the temperature of prebake is 80 ~ 120 DEG C.Preferably, the time of prebake is 2 ~ 4min.
Preferably, the temperature baked is 150 ~ 180 DEG C, and the time of baking is 3 ~ 5min.
The present invention makes full use of the characteristic that soluble polyurethane and chitosan molecule contain great amount of hydroxy group, amino isoreactivity group, guarantees the reaction chance that on its and protein macromolecule, active group is higher, increases crosslinking degree, lifting wrinkle resistance.The present invention takes full advantage of soluble polyurethane and can give than the better feel of silicone oil softener simultaneously and not affect hydrophilic advantage, while improving non-ironing smooth appearance degree, gives hydrophily and the feel of fabric excellence; The present invention utilizes soluble polyurethane can the characteristic of self-crosslinking film forming, improves the anti-wear performance after fabric anti-crease finishing;
Adopt method in the present invention, as carried out flatiron process to silk fabric, get damp again after process certain hour, gives the stronger feel of fabric and brute force; The present invention makes full use of after washing operation, gives product better hygroscopicity, and then improve its snugness of fit by adding a certain amount of bleeding agent in water lotion.
Silk fabric after application the inventive method arranges continues to keep good ventilative, moisture-inhibiting, smooth and draping property, gives smooth appearance and the comfortableness of such fabric excellence simultaneously.
The anti-crease finishing method of anti-crease finishing liquid disclosed in the present invention and silk fabric overcomes many disadvantages of the prior art and creative.
