Description
Technical Field
The invention relates to the technical field of textile treatment, in particular to a crease-resist treatment method for silk.
Background
Silk is a natural animal protein fiber, is rich in 18 amino acids required by human bodies, mainly consists of silk fibroin and sericin, and is the most main raw material for silk weaving. The silk has the advantages of moisture absorption, warm keeping, air permeability and the like, is smooth and soft in touch, is warm in winter and cool in summer, and has good extensibility and good heat resistance. The silk fabric can not only prevent the radiation of ultraviolet rays, defend the invasion of harmful gases and resist harmful bacteria, but also enhance the activity of skin cells on the body surface and promote the metabolism of the skin cells, and simultaneously has good auxiliary treatment effect on certain skin diseases, so the silk fabric is widely popular with consumers.
Wrinkling is a problem often encountered with silk during storage and use. The wrinkling is caused by that chemical cross-linking does not exist among protein molecules of the real silk fiber, only has bonding effects of hydrogen bonds, salt bonds and the like, and the amorphous area of the real silk fiber is as high as 50 percent. When the amorphous regions are acted by water molecules or other solvent molecules, the bonds are easy to be damaged, and the acting force among protein molecular chains is weakened, so that relative slippage and deformation among fiber molecular chains are easy to occur under the action of external force. When the action of water molecules or other solvents is removed, the macromolecules do not have enough binding force to return to the original position, and when the change is an irreversible process, the change is reflected in shrinkage and wrinkling of the silk fabric.
Disclosure of Invention
The invention aims to solve the technical problems and provide a crease-resistant treatment method for silk, which is used for crease resistance of silk and enhancing hand feeling.
In order to solve the technical problems, the technical scheme provided by the invention is as follows: a crease-resist treatment method of silk is characterized by comprising the following steps: (1) soaking silk in clear water at room temperature for 5-10min, taking out, air drying and hanging until no water drops; (2) soaking the silk obtained in the step (1) in an anti-wrinkling protective solution, wherein the bath ratio is 1: 20-30, the soaking temperature is 25-35 ℃, the soaking time is 40-50min, and the silk is dehydrated, wherein the water content of the silk is 40-50%; the anti-wrinkling protective solution is prepared from the following components in percentage by weight: 2-5% of crease-resistant protective agent, 2-3% of polyoxyethylene fatty alcohol ether composite emulsifier, 5-6% of sodium hypophosphite, 3.5-5% of softening agent, 0.5-1% of cross-linking agent, 0.5-0.8% of triethanolamine and the balance of water; (3) drying the silk treated in the step (2) in water vapor with the temperature of 70-90 ℃ and the humidity of 60-70 percent for 3 minutes; (4) repeating the step (2) and the step (3) on the silk treated in the step (3); (5) soaking the silk treated in the step (4) in vinegar water for 30-40 min; (6) and (4) washing the silk treated in the step (5), ventilating and drying at the temperature of 70-90 ℃, and naturally cooling.
Further, the preparation method of the wrinkle-resistant protective agent in the step (2) comprises the following steps: A. stirring allyl polyether under the condition of introducing N2, heating to 45 ℃, and adding end hydrogen-containing silicone oil to prepare hydroxyl-terminated polyether modified polysiloxane, wherein the molar ratio of the end hydrogen-containing silicone oil to the allyl polyether is 1: 1.2; B. stirring MDI under the condition of introducing N2, heating to 45 ℃, and then adding hydroxyl-terminated polyether modified polysiloxane and dibutyltin dilaurate to prepare an isocyanate-terminated polyether modified polysiloxane prepolymer, wherein the molar ratio of the hydroxyl-terminated polyether modified polysiloxane to the MDI is 1: 2.4; C. and (3) adding caprolactam into the isocyanate-terminated polyether modified polysiloxane prepolymer prepared in the step B under the condition of introducing N2, and reacting for 3 hours at 70 ℃ to prepare the anti-wrinkling protective agent.
Further, the softening agent in the step (2) is one or two of turkey red oil and sulfonated oil.
Further, the crosslinking agent in the step (2) is N-N' -methylene-bisacrylamide.
Further, the drying in the step (3) and the step (4) is sectional drying, namely, the silk is dried for 6min in the environment of the temperature of 80 ℃ and then dried for 4min in the environment of the temperature of 110 ℃.
Further, the vinegar solution in the step (5) is composed of vinegar and water, and the mass ratio of the vinegar to the water is 1: 8-10.
Compared with the traditional chemical crease-resistant and antibacterial finishing, the invention has the following advantages: the isocyanate has higher reactivity, and can improve the crosslinking degree with real silk fibers, thereby endowing the fabric with good crease-resistant effect; the polysiloxane can improve the problem that the strength of the fabric is reduced due to stress concentration, keeps the smoothness of the fabric, and improves the hydrophilicity of the fabric due to the addition of the hydrophilic polyether chain segment; the isocyanate group in the finishing agent is covalently and crossly bonded with the active group on the fiber, so that the finishing agent is difficult to wash off; therefore, the finished fabric shows good crease-resistant effect, and the fabric has good water washing resistance.
