Description

Anti-pilling polyester fabric based on silk fibroin-graphene oxide composite material and preparation method thereof
Technical Field
The invention relates to the field of textile clothing and functional textile materials, in particular to a silk fibroin-graphene oxide composite material-based anti-pilling polyester fabric and a preparation method thereof.
Background
The fuzz and pilling resistance of the fabric is generally divided into 5 grades. The best grade 5 indicates no pilling. The worst rank 1 indicates the worst pilling. Among the commonly used textile fabrics, terylene and acrylon are easy to fluff and pill. The reason why terylene is easy to fluff and pill is as follows: due to the loose yarn structure and the non-uniform supermolecule structure of the terylene, after the terylene fabric is subjected to the friction action, the fibers are easy to break, slide out of the surface of the fabric and are mutually entangled to form balls, so that the fluffing and pilling performance and the wear resistance of the terylene fabric are poor. The friction performance of the polyester fabric directly influences the appearance and the service life of the fabric. Therefore, the polyester fabric has important significance in improving the pilling performance and the wear resistance of the polyester fabric (the textile bulletin, 2019,40 (10): 134-140).
The resin finishing is a common after-finishing method, can effectively improve the wear resistance of the polyester fabric, and has the principle that the fibers are bonded through the resin, a layer of polymer film is formed on the surfaces of the fibers, and the winding of the exposed fibers on the surfaces of the fabrics is weakened, so that the good wear resistance is obtained. However, the common resin finishing agents such as polyurethane and the like can generate side effects on air permeability, moisture permeability, hand feeling and the like of the polyester fabric, so that the polyester fabric becomes stiff, and the wearing comfort is greatly reduced. And the adhesion between the resin finishing agent and the polyester fabric is poor, and the resin finishing agent continuously falls off after being washed for many times, so that the pilling performance of the polyester fabric is more and more serious.
Disclosure of Invention
In view of the above disadvantages, the present invention aims to provide an anti-pilling polyester fabric based on a silk fibroin-graphene oxide composite material, which has good anti-pilling, antibacterial, anti-ultraviolet, etc. functions, and has a silky hand feeling and luster.
The invention is realized by the following technical scheme:
the anti-pilling polyester fabric based on the silk fibroin-graphene oxide composite material comprises a polyester fabric and a silk fibroin-graphene oxide composite material layer coated on the surface of the polyester fabric.
The invention also provides a preparation method of the silk fibroin-graphene oxide composite material-based anti-pilling polyester fabric which has good anti-pilling, antibacterial, ultraviolet-resistant and other functions, has silk-like hand feeling and luster, and is prepared from the silk fibroin-graphene oxide composite material.
The preparation method comprises the following steps: adding graphene oxide into thionyl chloride, wherein the mass/volume ratio of the mass of the graphene oxide in g to the volume of the thionyl chloride in ml is 1-1.
Adding the acyl chloride graphene oxide into deionized water at a bath ratio of 1:50, adding silk fibroin powder, wherein the mass ratio of the acyl chloride graphene oxide to the silk fibroin powder is 1.
And (3) soaking the polyester fabric subjected to alkali decrement treatment in gamma-glycidyl ether oxypropyltrimethoxysilane for reaction for 24 hours at a bath ratio of 1.
The alkali decrement belongs to the prior art, and refers to a treatment process of a terylene fabric by using a NaOH solution at normal temperature or a certain temperature. The processed terylene fabric has soft hand feeling and soft luster. Because ester bonds are sensitive to alkali, in the alkali treatment process, firstly, ester bonds on the surfaces of an amorphous area and a crystalline area are hydrolyzed, then macromolecular aggregates in the fibers fall off in a whole block to cause the weight loss of the fibers, and grooves are reserved on the surfaces, so that the surface reflection is reduced by the grooves, and the fabric is soft in luster. When the concentration of the alkali solution is high and the treatment temperature is high, the phenomenon that the section of the polyester fiber monofilament becomes thin can even happen. The fiber is soft to the touch because of the thinning of the fiber. The fiber is formed into a groove and even thinned after the alkali treatment, the mass of the fiber is reduced, which is called as alkali weight loss, and the weight loss rate is generally controlled to be 20-25%.
The polyester fabric alkali deweighting process conditions used in the invention are as follows: 10g/L NaOH, the temperature is 80 ℃, the bath ratio is 1.
Preparing the fibroin-graphene oxide composite material into an aqueous solution with the mass fraction of 1% -5%, then soaking the gamma-glycidyl ether oxypropyltrimethoxysilane modified polyester fabric in the fibroin-graphene oxide composite material aqueous solution, reacting for 12-24 h at normal temperature, wherein the bath ratio is 1.
The invention has the beneficial effects that: (1) The polyester fabric prepared by the invention has a series of functions of pilling resistance, antibiosis, ultraviolet resistance and the like, and the pilling resistance is improved by at least more than 2 levels. In addition, the handfeel and the gloss of the silk fibroin-graphene oxide modified polyester fabric are greatly improved, and the grade and the additional value of the polyester fabric are greatly improved. (2) The epoxy groups on the surface of the gamma-glycidyl ether oxypropyltrimethoxysilane modified polyester fabric and the amino groups on the surface of the silk fibroin-graphene oxide composite material are subjected to open-loop covalent reaction, so that the silk fibroin-graphene oxide composite material layer cannot fall off in a large amount along with the increase of the washing times, and the stability and the adsorption fastness of the silk fibroin-graphene oxide composite material layer on the surface of the polyester fabric are greatly improved. Even after washing for 50 times, the pilling resistance of the polyester fabric is reduced by one grade, and the pilling resistance has long-acting performance. (3) Due to the existence of silk fibroin, the terylene fabric obtains silky hand feeling and luster to a certain degree.
