Description
Technical Field
The invention relates to the technical field of fabrics, in particular to a high-strength flame-retardant antibacterial fabric and a preparation method thereof.
Background
With the development of society, the requirements of people on fabrics are increasingly improved, especially in special occasions. The flame retardant property of the fabric is completely determined by the flame retardant property of the fabric fiber.
The flame-retardant fiber is a fiber which can not burn or can not burn sufficiently after being contacted with a fire source, only has small flame and can extinguish the flame quickly and automatically after the fire source is removed. Currently, the commonly used flame-retardant fibers are: PBI fibers, PVC fibers, PTFE, PPTA, pryianitz fibers, polyamide-imide fibers. The Prylanitz fiber has good hygroscopicity, does not melt under the action of radiant heat or flame, and can be used for a water-resisting vapor layer of fire-fighting clothing.
The autogenous fiber with flame retardant property has excellent solid flame retardant property, but has poor wearability and higher manufacturing cost, so that most of the existing flame retardant fibers carry out flame retardant modification on the traditional fiber. Proban finishing (Pulex finishing) of cotton fabrics is a common flame-retardant finishing method for the cotton fabrics, and is characterized in that low-molecular-weight aqueous solutions of tetrakis hydroxymethyl phosphonium sulfate, tetrakis hydroxymethyl phosphonium chloride and the like are adopted to be padded into the fabrics, the content of appropriate active ingredients is controlled, phosphorus compounds are infiltrated into amorphous regions and gaps of cotton fibers, the water content of the phosphorus compounds is controlled, then NH3 and hydroxymethyl groups in phosphorus precondensates are crosslinked through quantitative fumigation of ammonia gas, a flame-retardant polymer is formed inside the fibers, and a flame-retardant synergistic effect of phosphorus-nitrogen synergy is established; and then the trivalent phosphorus in the flame retardant in the fiber is converted into pentavalent phosphorus through oxidation, so that the flame retardant is further stabilized in the fiber. After the cotton fabric finished and processed by the method meets high-temperature flame, the phosphorus-containing compound is firstly decomposed to generate phosphoric acid or polyphosphoric anhydride which is not easy to volatilize, and the phosphoric acid or polyphosphoric anhydride and hydroxyl of cellulose are subjected to dehydration reaction to carbonize the fiber, so that the flame retardant effect is achieved. The fabric treated by the Proban method is soft in hand feeling, durable in flame retardant property, capable of bearing 50 (even 200) washes, still capable of keeping good flame retardant property and comfort of the fabric, suitable for being made into various protective clothing, bedding, decorative articles, flame retardant pajamas for children and the like, and is an important method for durable flame retardant finishing of cotton fabrics at present. But the biggest defect of the Pulubenzene finishing is that the breaking strength of the finished fabric is obviously reduced, and the strength is usually reduced by 20%; in particular, there is a significant reduction in tear strength. Thus, the application of such flame retardant processing techniques is seriously affected.
The common vinylon and the high-strength vinylon are both prepared by acetalizing hydroxyl groups of the PVA fiber with formaldehyde, and the hydroxyl groups in the PVA fiber are terminated with formaldehyde, so that the content of the hydroxyl groups in the fiber is greatly reduced, and the problem that the PVA fiber is easy to swell, adhere and dissolve is solved. However, the hydroxyl end-capping treatment by using formaldehyde has the problem of high requirement on the air tightness of hydroformylation processing equipment, and even if trace formaldehyde is leaked, the environment is polluted and workers are injured. Today, with increasing awareness of environmental protection, the use of formaldehyde as a method for controlling the hydroxyl content is not suitable for the current environmental protection requirements.
