Of all the scaffolds, knits display considerable deformability and good compliance owing to their looped yarn arrangement. Knits (non-woven) and foams display the lower end of mechanical properties. The next stiff and strong scaffold is the braid. Synthetic fibers can be Bio-Degradable and Non-Biodegradable and Natural fibers are Human, Plant, or Plant Tissue.Īmong the various materials used for scaffolds, woven fabrics are normally rigid and inflexible due to the tight interlacing of yarns. The scaffolds are made up of fibers which are synthetic and natural. Based on the application, they may be grouped into three broad categories, namely healthcare and hygiene textiles, extracorporeal devices and surgical textiles. Nowadays textile scaffolds are commonly used in various biomedical applications, and are generally referred to as ‘medical textiles’. Textile scaffolds are artificial devices, designed to act as templates for attached cells and newly formed tissues. The scaffolds are three dimensional, porous structures encourage cell attachment, proliferation and migration through an interconnected network of pores. The cells transplanted onto scaffolds multiply and produce tissue matrices that can take up and secrete protein, generate force and resistance, constrain permeability, and exhibit other life processes. The scaffold acts as an extracellular matrix for the adhesion and growth and/or regeneration of cells. The basic concept of tissue engineering is to regenerate or to grow tissues or organs by culturing isolated cells from the tissue or organ of interest on porous biodegradable scaffolds as templates. Textile structures are an important class of porous scaffolds used in tissue engineering. Moreover polymers reinforced with textiles, called polymer composite materials, are also considered in hard tissue replacements, spine rods, intervertebral disks and spin cages. Soft tissue replacement or implants such as vascular graft, skin grafts, hernia patches and artificial ligaments are made of textile filaments. They are routinely used to supplement or replace the functions of living tissues of the human body. Due to recent advancements in textile engineering and bio-medical research the use of textiles in surgery is growing. University of Management and Technology (UMT)Įmail: of textile structures in a medical field is not recent because sutures, which for centuries have been used for closure of wound or incision, or fundamentally textile structures.
