Hose capable of being flattened and manufacturing method thereof

Abstract

The invention discloses a hose capable of being flattened. The hose capable of being flattened comprises an inner rubber layer, an outer rubber layer and a cylindrical fabric layer which is positioned between the inner rubber layer and the outer rubber layer, wherein the inner rubber layer and the outer rubber layer are made of a thermoplastic polyurethane or polyvinyl chloride material; the cylindrical fabric layer comprises an outer enhancement layer and an inner enhancement layer; the outer enhancement layer and the inner enhancement layer are of independent plain, twill or satin weave structures which are formed by weaving warp yarns and weft yarns; the outer enhancement layer and the inner enhancement layer are bound by using the weft yarns. The invention also provides a manufacturing method of the hose capable of being flattened. The hose capable of being flattened can bear high conveying liquid pressure to further improve the conveying flow of the hose; the hose capable of being flattened has good softness under a storage condition and is convenient to coil or fold to store.

Description

technical field [0001] The invention relates to the field of liquid hoses, more specifically, to a flat liquid delivery hose with double-layer fabric reinforcement layers coated with glue on the inside and outside. Background technique [0002] The flattenable hose is a positive pressure delivery hose that uses a ring braid as a reinforcement layer, and the inside of the reinforcement layer or the inner and outer surfaces of the reinforcement layer are coated with rubber. The patent document with the notification number CN2646519Y discloses a coilable liquid conveying hose. The structure of the hose is the inner and outer layers of the high-strength synthetic fiber reinforced layer, and polyurethane elastomer is used as the rubber material. Hot coating, while forming the inner and outer rubber layers of the hose. The patent document with the notification number CN202082508U discloses a new type of liquid conveying hose. The hose is made of high-strength fiber reinforced lay...

AI Technical Summary

Problems solved by technology

[0003] The above two types of hoses all use a single-layer hose reinforcement layer. In order to improve the pressure bearing strength of the hose, the fineness of the warp and weft yarns and the density of the warp and weft yarns are increased. Due to the limitations of the structure and production equipment, there are the following deficiencies: : (a) simply increasing the fineness of the reinforcement layer will reduce the softness of the reinforcement layer and the corresponding hose products, making it difficult to flatten or fold the hose; (b) the increase in the thickness of the reinforcement layer also increases the subsequent coating process Difficulty, the hose is difficult to form
