Classification:
Multifunctional flame retardant fabric
Choose pure cotton gray fabrics containing conductive threads, adopt alkali-free cold padding pre-treatment, vat dye printing, step-by-step flame retardant finishing and water-repellent and oil-repellent finishingManagement, developedantistatic/flame retardant/water and oil repellent Multifunctional protective fabrics, and the key technical points of each production process are analyzed. The results show that the prepared multifunctional protective clothing has excellent antistatic, flame retardant, water and oil repellent properties and can meet the protection requirements in many fields. Keywords: multifunctional finishing; protective fabric; cotton fiber flame retardant cloth, cotton flame retardant cloth, nylon flame retardant cloth
Foreword:
With the development of society, people have more and more demands for multi-functional protective clothing. Multifunctional composite finishing refers to the finishing technology that gives textiles two or more functionse, such as flame retardant/antistatic composite finishing [1-3], anti- Anti-static/water-repellent and oil-repellent composite finishing[4], anti-UV/water-repellent and oil-repellent composite finishing[5], anti-UV/anti-static composite finishing[ 6], antibacterial/antistatic composite finishing [7], etc. However, at present, various functional finishing agentshave a relatively single role, and there are compatibility problems between single functional finishing agents, and some are difficult to use in the same bath. , some even deal with it step by stepand it is difficult to meet the corresponding protection requirements. In addition, some multi-functional composite finishes, such as flame-retardant/waterproof composite finishes, often use coating processes, whichmakes the fabric feel hard and has poor breathability, affecting its wearability. performance. If the impregnation treatment process is adopted, by optimizing the finishing agent and application process, can also obtain composite functions. At the same time, the treated fabric has better air permeability, moisture permeability, and soft hand feel. ,comfortable to wear. In response to customer requirements, this projectdeveloped a protective fabric with composite functions such as antistatic, flame retardant, water and oil repellency, and its production process is introduced below.
1 Production processFlame-retardant cloth, cotton flame-retardant cloth, nylon flame-retardant cloth
The process includes conductive silk gray cloth – singeing – pre-treatment – printing – flame retardant finishing – water and oil repellent finishing – fabric inspection – packaging
1.1 Choose flame retardant fabric, cotton flame retardant fabric, nylon flame retardant fabric
Chemical fiber fabrics have high strength, good abrasion resistance, and light weight. After flame-retardant finishing, the flame spread rate is reduced, but melt droplets will be produced when burning, which is very irritatingDanger to users; polyester/cotton blended fabrics are difficult to obtain durable flame retardant properties. Therefore, pure cotton fabric is selected, considering the strength requirements of the fabric, and uses high-count and high-density pure cotton fabric. Flame retardant fabric, cotton flame retardant fabric, nylon flame retardant fabric
There are two main ways to antistatic finish the fabric: one is to use an antistatic agent with hygroscopic effect to form a continuous layer ofConductive water film can conduct and dissipate static electricity; the second is to weave conductive threads into the fabric to conduct and dissipate the static electricity generated by friction to the outside world in time, anti-staticEffective and washable. Since the action mechanism of the antistatic agent is contrary to the water-repellent mechanism and is not suitable to be combined with the water-repellent function, pure cotton fabric containingconductive yarn is used.
