Problems solved by technology

The application of polyvinyl chloride in textiles has been studied for a long time at home and abroad. It is the main difficulty to take into account various requirements and comprehensive properties of materials and meet good processing properties. Often materials meet certain properties but at the expense of other properties. For example, the physical and mechanical properties of the material are greatly reduced while meeting the flame retardant and smoke suppression requirements, or the material has good use characteristics but the processability is difficult to meet the high requirements of textile extrusion, and it is difficult to process fine and uniform textile threads and textiles

Abstract

The invention discloses a material special for polyvinyl chloride textiles and a preparation method thereof. The material consists of the following components in part by weight: 50 parts of polyvinyl chloride resin powder, 15 to 45 parts of environmentally-friendly plasticizer, 2 to 5 parts of thermal stabilizer, 1 to 15 parts of flame retardant, 1 to 5 parts of smoke suppressor, 0 to 15 parts of filler, 0.5 to 1.5 parts of weather resisting agent, 0.1 to 1.0 part of antioxidant, 0.1 to 0.5 part of antibacterial agent, and 0.1 to 1.5 parts of processing aid. After the components are fully mixed, the mixture is extruded and granulated by a double-screw mixing mill with an automatic metering and baiting device to form the material. The method has good mixing effect, the quality of the product is stable, the processing efficiency is high, and the prepared particles have uniform size and bright appearance. The textiles produced by the material have the properties of flame retardancy, smoke suppression, weather resistance, bacteria resistance and the like; and the flame-retardant grade of the product reaches UL 94 V-0 grade, the smoke density (with flame) is less than 100, the antibacterial property meets the grade-one requirement of AATCC30, and the color fastness reaches the grade-6 standard of ISO105 B02.

Description

technical field [0001] The invention relates to a textile material and its preparation technology. Background technique [0002] Textiles come in a wide variety of applications and are often used outdoors. Outdoor textiles are exposed to harsh environments such as light, heat, and rain for a long time, so there are high requirements for the materials used, such as weather resistance, antibacterial, flame retardant, etc. Polyvinyl chloride (PVC) has rich sources, low price, convenient processing and excellent performance, and has become one of the main polymer materials used in textiles. [0003] The main feature of outdoor textiles is that they will not change color after long-term exposure to the sun, which puts forward high requirements on the weather resistance of the material. PVC used as a textile material is generally coated on the surface of nylon or polyester filaments by extrusion, so PVC has become the best weather resistance for textiles. important barrier. Lik...
