A flexible composite textile substrate can be formed

A composite coated fabric is a textile product with a coating that enhances certain qualities or adds new ones. This type of fabric is also known as a laminated or bonded textile. The coating may consist of various substances such as plastics, rubbers and resins, polyvinyl chloride (PVC), phenolic compounds or other metals. The coating may be applied to either the surface or through the entire fabric, and it can be woven into the fabric or applied as an adhesive layer. Coatings are often used to protect the fabric from chemical or mechanical damage, and they can improve its durability by making it more impervious to punctures, cuts and stains.

A flexible composite textile substrate can be formed by coating a nonwoven or woven fabric with a continuous polymer layer, or by laminating two or more textile substrates together using an adhesive polymer layer. The flexible composites retain the characteristic properties of the underlying fabrics. In contrast, inflexible composite substrates are made by imbedding fiber webs, fiber tows or agglomerated filaments into a stiff polymer matrix. The rigidity of these inflexible materials makes them suitable for use in applications requiring high performance, but they lose the flexibility of their underlying textile substrates.

Various laboratory tests can be used to characterize the properties of coated woven and non-woven fabrics. Among these are uniaxial and biaxial tensile testing, which can be performed on an MTS 20/M tensile tester. Day analyzed the behavior of fabric heating elements with carbon nanofiber/Poly composite-coated cotton fabrics under biased tensile tests. The fracture surface of the tensile samples was monitored by scanning electron microscopy.

In this work, an all-polyamide (PA) composite-coated fabric (APCCF) is prepared through a phase inversion method by replacing the FA solvent with a non-phthalate environment-friendly plasticiser, namely, urea. The APCCF prepared with the urea solution has almost the same properties as that made through neat FA solvent, and is more tensile, water/gas tight, and abrasion resistant.

The thermal insulation properties of the composite coated fabric were investigated by varying the mass ratio of silica aerogel particles to potassium hexatitanate whisker, and the results showed that as the mass ratio increases, the thermal insulation performance first increases and then decreases. The composite coated fabric could be suitable for a wide range of semi-structural applications such as temporary houses and tents, facade coverings, container linings, and tarpaulins, and can also be used to develop textile bioreactors for ethanol/biogas production from waste biomass. The preparation of this all-polyamide composite-coated fabric is considered 'green', since it uses a non-phthalate plasticizer that is more environmentally friendly than FA. The preparation process is simple, cost-effective, and industrially feasible. The material is also completely recyclable and contains no other materials, except PA, which can be melted or dissolved for reuse.
