Elastic Textile Hose Structure for Heat and Abrasion Protection

The patent applies composite materials by combining a thermally insulating core (foam pipe or textile foam layer) with an outer protective textile layer made of abrasion-resistant fibers. This composite structure allows the hose to simultaneously achieve high thermal insulation capacity from the foam layer and high mechanical resistance against abrasion from the textile outer layer, resolving the contradiction between these two opposing requirements.

The patent resolves this contradiction by creating a composite structure where the textile fabric provides mechanical reinforcement and abrasion resistance as the outer layer, while an inner foam layer (EPS, XPS, or other thermal insulation materials) provides the thermal insulation capacity. This multi-layer composite design allows both functions to coexist without compromising either property.

The patent applies the merging principle by integrating multiple functional layers (thermally insulating layer and abrasion-resistant textile layer) into a single pre-assembled hose structure. This allows the hose to provide both thermal insulation and mechanical protection simultaneously while significantly reducing assembly effort, as the multi-layer construction is manufactured as one integrated component rather than requiring separate fitting of multiple layers during installation.

The patent applies parameter changes by utilizing the thermal expansion and contraction properties of the hose materials. The hose can be heated to expand its diameter for easy fitting over the elongated object, then cooled to contract and secure tightly. This parameter change approach allows easy installation through thermal expansion while the hose design maintains thermal stress resistance through appropriate material selection and layer configuration that can withstand repeated thermal cycles without degradation.
