Performance requirements and applications of automobile knitted interior fabrics

Four types of knitted fleece fabrics, three-dimensional spacer fabrics, multiaxial warp knitted fabrics and cushion fabrics used in materials automotive interior fabrics, highlighting that the automotive knitted interior fabric market has great potential.

In addition to the various properties of traditional textiles, it has excellent wear resistance, flame retardancy, light resistance and UV resistance, as well as color fastness. 1 Knitted fabrics are used in automobile interior materials. There are higher requirements in terms of strength, dirt repellent, ease of cleaning and dimensional stability.

2. 1 Textiles account for more than 50% of the wear resistance of automotive interior materials. Each knitted fabric should be usedused as a car seat material and as a carpet material (cars need abrasion resistance) was assembled with approximately 20 kg of textiles consisting mainly of: 3.5 kg of seat covers, 4.5 kg of carpet, 6 kg of other decisive Works) Decoration and tires, 6 kg of fiberglass reinforcement, where are the properties of the fibers used, the structure of the knits, the finishing treatment and the knitted and woven fabrics the two main categories . According to the international market [2], the influence of the amount of coating.

According to the statistical data, the application report of warp knitting, weft knitting and fabrics in car interior decoration fibers such as tensile, bending, shear and other mechanical properties to knitted fabrics is 45:16? 39, Knitted fabrics play an important role in this wear resistance. The tensile work [1] of nylon and polyesterr represents more than 60% of the total. Knitted fabrics have good stretchability, high elastic recovery and excellent wear resistance. However, nylon is soft and elastic, soft and comfortable to the touch, and has poor color fastness, such as structural stability and resistance to sunlight. The required standards, due to low dedispersibility, as well as various new fiber yarn raw materials and the application of polyester technology with excellent wear resistance as raw materials for dyeing and finishing the fabric of car seats, make it wear-resistant and flame-retardant. , antifouling, easy to clean and beat. It has gradually become the world\'s first choice of automotive interior fabrics, and its fiber length, linear density and cross-sectional shape provide broad development prospects. The wear resistance of tissu has some impact. Long fibers have better wear resistance than short fibers; finer fibers have better strength, elongation, and fatigue resistance; fibers with circular section shapes have better wear resistance than fibers with special section shapes.

2 Performance requirements of knitted automotive interior fabrics Yarn structure, knit structure, warp and weft density and surface density have a significant impact on resistance to wear of knitted fabrics. The effect of weave structure on abrasion resistance is actually the support of the knit surface. The design of large-area knitted automotive interior fabrics requires comfort, beauty, economy and little influence of the number of contact points between the yarns; under the same conditions, durability, perHigh process formances, UV resistance and radiation resistance are also required, as well as warp and weft density, surface area. Knitted fabrics with higher density are thicker, stronger and more wear-resistant
