Description
Technical Field
The invention relates to the technical field of textile finishing, in particular to a water-resistant and oil-repellent finishing method for a woolen and worsted fabric.
Background
Along with the improvement of living standard of people, the quality requirement of clothes worn by people is higher and higher, especially when people go in and out of various important places. The worsted fabric has the advantages of smooth and clean surface, fine and clear texture, soft and natural luster, pure color, soft hand feeling, high elasticity and the like, and is popular among people. The general worsted fabric is made of high-grade wool, and has the advantages of more manufacturing processes, more complex flow and higher cost. In recent years, more and more manufacturers utilize the idea of roving spinning as a raw material in order to reduce the cost, and produce fabrics with appearance and hand feeling similar to worsted fabrics by improving weaving and after-finishing processes.
The worsted and refined fabric is generally made by spinning and post-finishing woolen yarns containing wool and yarns such as terylene, spandex or core spun yarn which can increase the elasticity and the stiffness of the fabric, and has the advantages of good elasticity, soft hand feeling, good stiffness and smoothness and the like. The garment made of the woolen spinning fabric has the advantages that due to the fact that yarns such as wool are high in hydrophilicity, dirty water, oil stains and the like can be absorbed immediately after being dripped on the garment, and the garment can be kept clean and tidy only by frequent replacement and cleaning. However, too frequent washing of the clothes can damage fibers in the fabric, so that the clothes have the defects of color change, fading, wrinkling, shrinkage deformation and the like. In order to keep the appearance and shape of the fabric, the fabric is subjected to water-resistant and oil-resistant finishing, so that the washing times of the fabric can be reduced, and the added value of the fabric is improved.
In the prior art of water-and-oil-repellent finishing of fabrics, most of the water-and-oil-repellent finishing liquid is padded in the post-finishing process, so that a layer of hydrophobic protective film is formed on the surface of the fabric, and the water-and-oil-repellent effect of the fabric is realized. In order to enable the fabric fibers and the hydrophobic protective film to be tightly combined, a synergist for catalyzing the reaction of the fibers and the finishing liquid is often required to be added into the finishing liquid, the fabric is required to be baked at a high temperature of 170 ℃, and the hand feeling of the fabric is hardened by baking the fabric at the high temperature or for a long time.

The further preferable technical scheme is that the mass percentage of the organic silicon compound in the organic silicon compound solution is 20-30%, and the organic silicon compound comprises silica sol, nano-silica and silanol.
In the step of spraying the organic silicon compound solution, the feeding flow of the solution is 400-800 mL/h, the spraying pressure of a spray gun is 0.5-1 Mpa, the atomizing pressure is 0.6-0.8 Mpa, the advancing speed of the fabric drawn by a drawing roller is 2-5 m/min, the baking time of the fabric is 3-5 min, and the baking temperature is 80-95 ℃.
According to a further preferable technical scheme, the water-resistant oil-repellent finishing liquid comprises a water-resistant oil-repellent agent with the mass fraction of 10-14%, and the water-resistant oil-repellent agent is a fluorine-containing polymer and comprises perfluoropolyether-based alkoxy silane, fluorine-containing alkyl acrylate, perfluoropolyether silane and fluorocarbon silicone resin.
According to a further preferable technical scheme, in the step of padding the water-resistant and oil-repellent finishing liquid, the fabric is soaked for 10-20 min at a bath ratio of 1: 30-40 at a drying temperature of 100-120 ℃ for 1-3 min.
According to a further preferable technical scheme, in the decating step, the steaming pressure is 0.1-0.3 Mpa, the time is 3-5 min, and the steaming temperature is 110-120 ℃.
When the fabric is pretreated, the ultrasonic cleaning is firstly adopted to remove dust, oil stain, dirt and the like attached to the surface of the fabric in the after-finishing process of the fabric, and the lotion used in the ultrasonic cleaning is neutral and almost has no damage to the fabric. After ultrasonic cleaning, plasma treatment is carried out on the fabric, and the plasma treatment is mainly used for enhancing the surface activity of fabric fiber groups, so that the fibers in the fabric can be better combined with substances on the surface. Argon, nitrogen and oxygen are used as working gases, ionization is carried out through the electromagnetic action, ionized positive ions move to the surface of the fabric at a high speed, and dust, dust and the like adhered to the surface of the fabric can be removed.
After the surface of the fabric is subjected to plasma activation treatment, the organic silicon compound solution is uniformly sprayed on the surface of the fabric, and the surface groups of the fabric fiber have stronger activity, so that the organic silicon compound can perform crosslinking reaction or form chemical bonds with the surface groups of the fiber after spraying, and can be firmly attached to the surface of the fiber, and the organic silicon compound such as silica sol can also interact with each other, and a reticular film is formed on the surface of the fabric through dehydration and condensation and is attached to the surface of the fabric. The organic silicon compound is insoluble in water, is often used as a waterproof material in the fields of textile, chemical engineering and the like, in addition, the organic silicon is very friendly to fabrics and is often used as a soft finishing agent in the textile field, and the fabrics treated by the organic silicon have the advantages of soft hand feeling, good rebound resilience, washability, wear resistance and the like.
The fabric which is coated with the organic silicon compound on the surface is dried and is put into a solution containing a water-resistant and oil-repellent finishing agent for padding treatment, the main component of the water-resistant and oil-repellent finishing agent is a fluorine-containing polymer comprising perfluoropolyether and the like, and the fluorine-containing polymer has low surface energy, so that the wetting property of liquid such as oil stain and the like on the surface of the fluorine-containing polymer is poor, and therefore, the fluorine-containing polymer is widely applied to the fields of mobile phones, vehicles, textiles and the like and is used as fingerprint-resistant materials, waterproof materials and the like. According to the invention, by utilizing the characteristic that the fluorine-containing polymer can be subjected to condensation reaction with hydroxyl (Si-OH) in the organic silicon compound, the organic silicon compound is firstly coated on the surface of the fabric, so that the fabric and the organic silicon coating form stronger bonding force, and then the fabric is immersed in the fluorine-containing polymer finishing liquid, so that the fluorine-containing polymer and the organic silicon are subjected to chemical reaction, and the purpose of firmly bonding the water-resistant oil-repellent finishing agent and the fabric is achieved.
In order to improve the luster and the hand feeling of the fabric and further improve the grade of the fabric, after the water-resistant and oil-repellent finishing is carried out on the fabric, the fabric needs to be subjected to decating treatment. After decating treatment, the fabric shrinks under heat, the structure becomes more compact, the fabric is pressed flat and pressed under certain pressure and tension conditions, the surface is smoother, the permeation of water drops and the adhesion of water drops are not facilitated, and the water repellency can be further improved.
