The function of textile is more and more diversified, the most practical or these eight!
1.water—repellenting
Concept: water-repellent finishing, also known as breathable waterproof finishing, that is, chemical water-repellent treatment, so that the fiber surface tension is reduced, resulting in water droplets can not wet the surface of the process.
Application: raincoat, travel bag and other waterproof materials.
Function: easy to handle, low price, good durability, and after water treatment of the fabric can still maintain its air permeability, mainly used for cotton, hemp fabrics, also can be used for silk and synthetic fabrics. The water-repellent finishing effect of fabric is also related to the fabric structure.
2. oil-repellenting
Concept: oil repellent finishing, the process of treating fabric with oil repellent finishing agent and forming oil repellent surface on fiber.
Application: high-grade raincoat, special clothing materials.
Function: after finishing, the surface tension of oil repellent fabric is lower than that of all kinds of oil, so that the oil is beaded on the fabric and not easy to penetrate into the fabric, thus producing oil repellent effect. The fabric treated by oil repellent fabric has both water repellent and good air permeability.
3.antistaticing
Concept: Antistatic finishing is a process in which chemical agents are applied to the fiber surface to increase its hydrophilicity and prevent the accumulation of static electricity on the fiber.
Cause of static electricity formation: Fiber, yarn or fabric in the process of processing or use due to friction will generate static electricity.
Function: improve the hygroscopicity of fiber surface, reduce the surface specific resistance, reduce the electrostatic phenomenon of fabric.
4. soil--releaseing
Concept: Easy decontamination finishing is the process of making the dirt on the surface of the fabric easy to be removed by ordinary washing methods and preventing the dirt from coming back during washing.
Cause of dirt formation: dirt is formed during the wearing of fabric due to the adsorption of dust and human excreta in the air and dirt. General fabric surface hydrophilicity is poor, good hydrophilicity, washing water is not easy to penetrate into the fiber gap, but after washing suspended in the detergent dirt is easy to re-stain to the fiber surface, causing re-contamination.
Function: reduce the surface tension between fiber and water, increase the hydrophilic fiber surface; Increase the antistatic property of the fabric, make the fabric comfortable to wear, feel soft, but the tear strength of the fabric decreased.
5.rot ptoofing
Concept: Mildew and corrosion resistant finish is generally applied to cellulose fabric with chemical mildew inhibitor to kill or prevent microbial growth. Generally choose to use relatively safe salicylic acid and other mildew inhibitor treatment, can also be used more water-resistant leaching of copper naphthenate mildew inhibitor for rolling treatment.
Causes of bacterial formation: in hot and humid climate, when textiles contain pulp and fat and other substances, microorganisms are easy to reproduce. Enzymes secreted by bacteria, actinomyces and molds can decompose fibers into their food and cause fiber damage.
6. moth proofing
Moth formation reason: because wool fabric susceptible to moth, moth larvae in the process of growth with wool fiber as food.
Effects: some organic compounds containing chlorine are commonly used as moth prevention agents. Its advantages are odorless color, targeted to wool fabric, more washable and non-destructive to the style of wool fabric and wear performance, easy to use, high safety for human body.
7. flame—retardaning
Principle: Flame retardants decompose to produce non-flammable gases, thus diluting flammable gases and acting as a shield for air or flame suppression. Flame retardants or their decomposition material melting cover in the fiber to play a shielding role, so that the fiber is not easy to burn or prevent carbon fiber oxidation.
8. coating
Concept: Coating finish is the process of coating or bonding a layer of polymer material on the surface of a fabric to give it a unique appearance or function.
Application: eiderdown, waterproof and moisture permeable, heat insulation, flame retardant, conductive, leather and other fabrics.
Concept: The most commonly used moth-proof finish in dyeing and finishing production is the chemical treatment of wool fabric to kill borers, or to change the structure of wool fiber so that it is no longer food for borers, so as to achieve the purpose of moth-proof.
Concept: textile after some chemical treatment can meet fire is not easy to burn, or a fire extinguish, this processing process is called flame retardant finishing, also known as fire finishing.
