Abstract

The invention relates to a three-dimensional spacer fabric reinforced space membrane material, a preparation method and a processing device thereof. The preparation method includes: in a three-dimensional spacer fabric running process, firstly applying tension along the fabric running direction and maintaining the tension unchanged, making spacer yarns in the fabric at a vertically straight state,then disposing an opening with a length equal to the width of the fabric at the fabric top cloth surface along a direction perpendicular to the fabric running direction, letting the upper layer and lower layer of the fabric staggered horizontally and the spacer yarns at an inclined tense state, and finally compounding the composite fabric with a membrane material to obtain the three-dimensional spacer fabric reinforced space membrane material. The processing device includes a cloth feeding roll, a tension roll, a sizing mechanism, a shaping mechanism, a lamination mechanism, a post-treatmentmechanism and a collection mechanism that are arranged in sequence. The final product has a composite layer structure including a plurality of membrane materials layers and a fabric layer between themembrane material layers, and the spacer yarns in the fabric can move freely and have no adhesion. The preparation method provided by the invention is simple in process, the processing device has a simple structure, and the product has excellent mechanical properties.

Description

technical field [0001] The invention belongs to the field of new textile materials, and relates to a three-dimensional interval fabric reinforced space membrane material, a preparation method and a processing device thereof. Background technique [0002] With the progress of society, people have higher and higher requirements for textiles, and their enthusiasm for research and development of materials is high. There are many new high-performance materials emerging on the market today. Facing the continuous impact of various emerging high-performance materials, the progress of textile composite materials is also quite fast. [0003] At present, most traditional composite materials are rigid materials, which are made of highly oriented yarns in fabric pre-components after resin curing. Although it has the characteristics of high strength, high modulus and strong tensile resistance, it can be used in advertising, industrial and other scenarios, but its rigidity is relatively ...
