Description

Technical Field

[0001] The present invention belongs to the technical field of fabrics, and more specifically, relates to a clothing fabric and a preparation method and application thereof. Background Art

[0002] Polylactic acid fiber is a kind of fiber extracted from corn, wheat and other raw materials. This fiber does not use petroleum, has good biodegradability, biocompatibility and bioabsorbability, and has excellent mechanical properties of both synthetic fibers and natural fibers. It has received more and more attention and is a sustainable ecological fiber. However, polylactic acid fabrics are flammable, produce a lot of heat and smoke when burning, and are very likely to promote the spread of fire, causing serious harm to human production, life and even life, which to a certain extent limits the development and wide application of polylactic acid fabrics.

[0003] CN114921870A discloses a flame-retardant polylactic acid fabric and a preparation method thereof, wherein the fabric can be prepared by the following method: first, reacting terminal hydroxyl polydimethylsiloxane, dimethyl phosphate and hexachlorocyclotriphosphazene to prepare nitrogen-containing phosphorus silicon flame retardant; then, blending the nitrogen-containing phosphorus silicon flame retardant with polylactic acid particles, spinning to prepare polylactic acid fibers; finally, spinning and weaving the polylactic acid fibers to prepare flame-retardant polylactic acid fabric. The initial limiting oxygen index of the flame-retardant polylactic acid fabric prepared by the present invention reaches more than 35%, which belongs to the range of flame-retardant materials; after 10 times of water washing, the limiting oxygen index does not decrease significantly, and still reaches more than 32%. The flame-retardant polylactic acid fabric prepared by the method of the present invention has strong flame retardancy, the entire production process is simple, the price is low, and the production process has little environmental pollution.

[0004] CN113151922A discloses a flame retardant polylactic acid fiber elastic fabric and a preparation method thereof, and relates to the technical field of new materials. The invention first reacts phloroglucinol with an alkylating agent, and then continues to react with sodium lignin sulfonate under the action of potassium iodide to obtain modified lignin, then mixes the modified lignin with nano metal powder to obtain modified nano metal, then reacts bacterial cellulose with maleic anhydride to obtain modified bacterial cellulose, reacts the modified nano metal with epoxy soybean oil under the action of a tertiary amine catalyst, and then reacts with the modified bacterial cellulose to obtain a modified additive, and finally adds the modified additive and plasticizer to polyethylene, extrudes, melts and spins to obtain a polylactic acid fiber blank, and then hydrothermally carbonizes, spins and weaves the polylactic acid fiber blank to obtain a flame retardant polylactic acid fiber elastic fabric. The flame retardant polylactic acid fiber elastic fabric prepared by the invention has excellent conductivity and flame retardancy, and good mechanical properties.

[0005] By co-spinning flame retardant components with polylactic acid, polylactic acid with flame retardant properties can be produced. However, the cost of adding and preparing the flame retardant components is high or the components are easily washed away, which results in a decrease in flame retardant properties after multiple washings.
