New knitted clothing, as a first layer on the skin, with knitted-in skin abrasion protection in case of falls.

Abstract

The three-dimensional knitting system (Figure 1) is characterized by a three-layer, interlocking knit structure. This structure integrates multiple functional zones into a seamless knit, ensuring a synergistic combination of protection, flexibility, and breathability. The three main components of the knitting system are: Outer layer (abrasion layer) (Figure 2) Middle layer (shock absorption layer) (Figure 3) Inner layer (comfort and moisture management layer) (Figure 4)

Description

[0001] The subject of the utility model is a three-dimensional, elastic knitting system for the production of functional underwear, which is produced using the H-PEA ® -fiber is manufactured according to the protection claim described below. This knitting system combines multiple layers of material in a continuous production process, with each layer specifically fulfilling different functions.

[0002] The right to protection includes in particular: • The structured combination of protection, stretch and ventilation zones in a textile knit. ( Fig. 5) • The seamless integration of shock-absorbing properties using defined knitting patterns ( Fig. 6) • The application of the knitting system for use in protective clothing against skin abrasion during sports or professional use ( Fig. 1) Derivation and justification of the need for protection

[0003] The innovation of the knitting system does not lie in the isolated use of known materials or simple textile structures, but in the synergistic new combination and functional development of a three-dimensional knitting system with defined protective parameters. ( Fig. 1)

[0004] Previously known systems in the field of protective textiles offer either high protection with low flexibility or pleasant wearing comfort with reduced protective effect. Our H3D knitting system ® closes this gap with a specifically designed layered knitting process that combines the following features: • Mechanical shock absorption in falls at speeds up to 30 km / h (proven by RMT testing) • High breathability through targeted arrangement of air-permeable zones ( Fig. 5) • Maximum elasticity and comfort thanks to an elastic layer system with adaptive recovery behavior

[0005] This combination has not yet been realized in any known prior art and therefore meets the requirements of novelty, industrial applicability and technical inventiveness required for utility model protection. Possible applications

[0006] The knitting system (protection claim) is particularly suitable for the following applications: • Sports textiles: For cycling, motorcycling, horse riding, skating and similar activities where falls and skin abrasions are common. • Workwear: For occupational groups with an increased risk of falls or intensive physical activity, e.g. in the construction industry, in logistics or in the emergency services. • Nursing clothing: For people with limited mobility or in geriatric care, where falls often cause skin injuries. • Children’s clothing: protective textiles for small children during the learning phase of walking or when playing outdoors.

[0007] The functionally integrated textile system formulated in the protection claim, which, through the combination of material innovation and advanced knitting technology, offers previously unattained protective properties while simultaneously providing high levels of comfort, represents a novel innovation. The structure is particularly suitable for use in functional underwear with a protective function against skin abrasions during physical exertion. Structure and function of the layers in the knitting systemOuter layer - abrasion layer (Figure 2) • Material: High molecular weight H-PEA ® -Fiber (High Performance Elastomeric Aramid), specially treated to increase abrasion resistance. • Knitting system: The knitting system is characterized by the outer layer being manufactured using a dense, staggered plating technique, which is optimized by targeted reinforcement with laid threads. This technique combines a very high stitch density with a staggered structure that minimizes fiber adhesion to the surface and provides a particularly stable texture. This knitting system creates fine, tight-knit structures (28-32 g / m²) that benefit abrasion resistance by evenly distributing mechanical forces across the entire surface. The use of laid threads further strengthens the surface structure, making the fabric more resistant to localized loads. Middle layer - shock absorption layer (Figure 3) • Material: Special elastomeric yarns with thermoplastic properties, combined with volume-giving polypropylene hollow fibers. • Knitting system: The knitting system in this layer is characterized by its use of a space-structuring 3D stitch weave with variable stitch density. The vertical density is 2-5mm between the top and bottom layers. The horizontal stitch density is between 14-20Gg, and the air content within the structure is 60-80%. This newly developed construction creates a three-dimensional textile fabric with increased volume and an air cushion effect between the layers, which acts as a cushioning buffer. The stitch density is differentiated in different areas, resulting in zonal adaptation of shock absorption. In critical areas, such as the chest or hips, the stitch density is denser to achieve greater cushioning, while in less stressed areas the density is reduced to ensure flexibility. Inner layer - comfort layer (Figure 4) • Material: H-PEA® -Fiber with a skin-friendly finish (antibacterial, pH-neutral), supplemented with Tencel™ or Modal yarns. • Knit system: The knit system in this layer is characterized by its use of a fine-threaded, soft single-jersey weave, complemented by newly developed micro loops (24-28g). This newly developed structure not only provides a smooth, skin-friendly surface but also efficient moisture wicking. The even distribution of fibers and the finely structured yarn achieve excellent breathability. Micro loops on the inside also promote moisture wicking and provide a cooling effect on the skin. This construction, with a surface weight of 120-160g / m2, minimizes friction and offers a comfortable feel, even during longer activities. Structural principle and zoning (Figure 5 & Figure 6)

[0008] The knitted fabric is not homogeneous, but has specifically integrated functional zones that are adapted to the load profile.
