Fabric finishing process

Fabric finishing process
1. Pre-shrink
Shrinkage is a physical method to reduce the shrinkage after fabric soaking to reduce the shrinkage of the process. Mechanical shrinkage is the fabric by the first spray or spray to wet, and then applied by the mechanical extrusion, the buckling wave height increases, and then loose dry.
2. Tentering
Tenter is the use of cellulose, silk, wool and other fibers in wet conditions have the plasticity, the fabric width gradually widened to the required size for drying, the fabric form to stabilize the process, also known as the fixed-size finishing.
3. Sizing
Sizing refers to the fabric dip coating slurry and drying to get the feeling thick and stiff finishing effect.
4. Heat setting
Heat-setting is to make the thermoplastic fiber and blended or interwoven fabric relatively stable process, mainly for heat-shrinkable deformation of nylon or polyester and other synthetic fibers and blends of processing. The heat-setting fabrics, can improve the dimensional stability, feel more stiff.
5. Whitening
Whitening is the use of light complementary principle to increase the whiteness of the textile process, also known as whitening. Whitening methods are blue and fluorescent whitening two.
6. Calendering, electro-optic and embossing
Calendering is the use of fiber in the hot and humid conditions of plasticity rolling the surface of the fabric or rolled parallel to the fine twill, in order to enhance the luster of the fabric process. Flat rolled light is composed of hard roll and soft roll hard rolling point, the fabric after rolling, the yarn is flattened, the surface is smooth, shiny, feel stiff. Soft-rolled light is composed of two soft roller soft-rolling point, the fabric after rolling, the yarn slightly flat, soft, soft, soft touch.
Electro-optic is the use of electricity heated roll on the fabric calendering.
Embossing is embossed with a pattern of steel roller and soft roller form rolling point, under hot rolling conditions, the fabric can be obtained luster pattern.
7. Friction, sanding
With sand roller (or belt) to the surface of the fabric mill out a layer of short and dense fluff process known as the velvet, also known as sanding, sanding finishing warp and weft yarn can produce fluff, and fluff short and dense.
8. fluff
Lint is dense needles or thorns to the fabric surface of the fiber pick up, forming a layer of fluff process, also known as brushed finishing, fluffing is mainly used for woolen fabric, acrylic fabric and cotton fabric. Fleece layer can improve the thermal insulation of the fabric, improve the appearance and make soft feel.
9. shearing
Shearing is the use of a shearing machine to cut the surface of the fabric unwanted hair process. Its purpose is to make the fabric textured clear, smooth surface, or to fluff, nap fabric nap or suede neatly. General wool, velvet, artificial fur and carpet products need to shear.
10. soft
Soft finishing There are two kinds of mechanical finishing and chemical finishing methods, mechanical softening finishing is achieved by rubbing the fabric several times to achieve, after finishing softening effect is not satisfactory. Chemical softening is applied to the fabric softener to reduce the friction coefficient between the fibers and yarns, so as to obtain a soft, smooth and feel, and the finishing effect is significant.
11. Stiff finishing
Fabric dipping slurry and drying to get thick and stiff effect of the process is to improve the fabric feel for the purpose of the finishing method. The use of a slurry made of natural or synthetic polymers with a certain viscosity forms a film on the fabric, giving the fabric a smooth, stiff, thick, full-bodied feel and enhancing fabric strength and abrasion resistance.
12. Liquid ammonia finishing
Liquid ammonia treatment of cotton fabric, to eliminate the internal stress in the fiber to improve its luster and service performance, reduce shrinkage of the fabric, increase resilience, breaking strength and hygroscopicity, soft, good elasticity, wrinkle resistance and dimensional stability.
13. Weight gain
Weight gain is mainly to make up for the weight loss of silk after degumming, the use of chemical methods to increase the weight of the silk fabric process. The main methods: tin plus method, tannin weight method (not applicable to white or light-colored silk fabric), resin weight gain.
14. Weight loss
Weight loss finishing is the use of polyester at a higher temperature and a certain concentration of sodium hydroxide solution hydrolysis, the gradual dissolution of the fiber, fabric weight reduction (generally controlled at 20% -25%), and the formation of a number of depression on the surface so that The surface of the fiber reflects light diffuse reflection, the formation of a soft luster, while increasing the gap in the fiber yarn to form a silk-style process.
15. Cook it
It is a cooking under the tension of the wool fabric with hot water bath to make it smooth order and subsequent wet processing is not easy to deform the process. Mainly used for worsted wool fabric finishing, after singeing and washing it. Boil finishing can make the fabric get good dimensional stability, to avoid deformation after wet processing, wrinkles, feel also improved.
16. Steamed it
Steamed tidy is the use of hair fibers in hot and humid conditions of the stereotypes, the steaming through the wool fabric form stable, feel, gloss improved process. Steamed it is mainly used for wool fabrics and blended products, can also be used for silk, viscose and other felt fabrics, steamed it after finishing the fabric size and shape stability, it is smooth, shiny natural, soft and flexible feel.
17. Pressure it
Pressure finishing is in the hot and humid conditions to the mechanical pressure to make the fabric smooth, in order to enhance the luster, improve the feel of the process. There are two ways to pressure it: one is the rotary pressure it, also known as hot it, the wool fabric by the steam spray evenly to the wet, in the heating of the cheese and the arc with the matching bed by pressing and friction Comfort ironing flat, and give gloss, but the effect is not lasting. The other is the electric board it, the fabric after the soft gloss voltage, feel crisp, temporary effect, but the equipment is huge, the production efficiency is low, mainly for worsted fabric.
18. Milling
Milling is the use of wool wool shrinkage so that the wool fabric thick and dense on the surface of the formation of fluff process, also known as shrinking it. Milling can improve the fabric feel and appearance, increase its warmth. Milling is especially suitable for woolen fabrics.
19. Anti-shrinkage
Anti-felting finishing is to prevent or reduce the wool fabric shrinkage in the washing and taking deformation, the size of the garment size process. The principle is to chemically etch the scales locally, change their surface condition, or coat their surface with a layer of polymer, as well as stick the interlacing points of the fibers to remove the felting base.
20. Wrinkle
Anti-wrinkle finishing is to change the original composition of fiber and structure, improve its resilience, so that the fabric is not easy to take wrinkle in the process. It is mainly used for pure or blended fabrics of cellulose fibers, but also for silk fabrics.
twenty one. Wrinkles
Wrinkle finishing is to make the fabric formation of different and irregular wrinkles of the process. The main methods are: one is the method of mechanical pressure to make the fabric irregular irregularities appearance wrinkles, such as hand-creased, rope-like wrinkles, packing, etc .; the other is the use of rubbing wrinkles, such as liquid flow Dyeing and drying drum wrinkles and so on. Mainly used for cotton cloth, polyester / cotton blend and polyester filament fabrics.
twenty two. Water finishing
Water repellent finishing is the use of chemical water repellent treatment, the fiber surface tension decreases, resulting in water droplets can not wet the surface of the process, also known as breathable waterproof finishing. Applies to raincoats, bags and other materials. According to the durability of water repellent effect, can be divided into two semi-durable and durability.
twenty three. Refueling finishing
Oil repellent finish is the process of treating the fabric with an oil repellent to form an oil repellent surface on the fiber. After finishing the fabric of oil repellent, and can resist water, and have good breathability. Mainly used for senior raincoats and special materials.
twenty four. Anti-static finishing
Synthetic fabric due to low moisture content, high crystallinity, easy to generate and accumulate static electricity. Antistatic finishing is applied to the fiber surface chemical agents to increase the hydrophilic surface to eliminate or reduce the static electricity on the fiber process. The main method is to form a conductive layer on the surface of the hydrophobic fibers to hydrophilize the surface of the fibers and ionize the surface of the fibers. Fabric anti-static finishing effect and durability are not as good as weaving with conductive fibers, yarn to blend or interweave more effective.
25. Easy to decontamination finishing
Easy decontamination finishing is to make the dirt on the surface of the fabric easy to use general washing method to remove, and to wash the dirt will not be washed in the process of pollution of the process. The basic principle of easy decontamination finishing is to chemically increase the hydrophilicity of the fiber surface and reduce the surface tension between the fiber and the water. It is preferable that the surface hydrophilic layer can swell when wetted to generate mechanical force to make the dirt Can automatically leave. Pad a layer of hydrophilic polymer material on the fabric surface.
26. Mildew preservative finishing
Mildew preservative finishing is generally applied to the cellulose fiber fabric chemical fungicide to kill or prevent the growth of microorganisms. In order to prevent the mold during the storage of textiles rot, available no significant effect on product color and color fastness, human health is also relatively safe salicylic acid and other preservatives for open-air rain conditions, the use of cellulose fiber textiles, Available more water-resistant preservatives leaching padding treatment, cellulose fibers after denaturation, but also have good mildew preservative performance.
27. Fang Zhu finishing
Anti-moth finishing is mainly aimed at the wool fabric easy to moth-eaten, while the wool fabric chemical treatment, poisoning borers, or changes in wool structure, is no longer a food for moths, so as to achieve the purpose of moth protection.
28. Flame retardant finishing
Textiles after some chemicals deal with the case of fire is not easy to burn or a burning that is extinguished, this process is called flame retardant finishing. Its main principle is to change the reaction process when the fiber is ignited, and generate a material with strong dehydration under the conditions of combustion, so that the fiber is carbonized and the flammable volatile material is not easily generated, so as to prevent the flame from spreading. Flame retardants decompose to produce non-flammable gases that dilute flammable gases and act as a shield, making the fibers less combustible or preventing carbonized fibers from oxidizing.
29. Coating finishing
Coating finishing is the fabric surface (or both) evenly coated with one or more film covering. Coatings are more and more widely used in modern fabrics. Add some additives to the polymer materials to make the coated fabrics have a variety of special properties.
30. Luminous finishing
Luminous-coated fabrics create a special-purpose garment that produces bright marks on matte or dark nights. Photoluminescent solid inorganic and organic two, mainly high-purity sulfide.
31. Reflective finishing
Reflective finishing is the use of glass beads or colored transparent plastic microspheres adhere to the fabric surface of a processing method. Reflected through the fabric after the fabric in the dark encounter the beam can produce directional reflection.
32. Anti-UV finishing
UV finishing is mainly added to the natural fiber fabric UV protection (UV reflectance or UV absorbers), there are two main ways: padding and coating method.
33. Antibacterial deodorant finishing
Antibacterial deodorant finishing is the use of antibacterial substances on the human body, through chemical bonding so that they can remain on the fabric, after a slow release to achieve the role of antimicrobial. The most common method is the silicone quaternary ammonium method
