Textile braid geometry

Dqiending on the final application of a textile scaffold, warp knittii weaving, braiding and non-woven technologies can be used to manufacture the textile structure. Thermal treatment can be iqqilied to adjust the pmoshy, geometry and elasticity of the produced textiles. 

The use of alginate in textile scaffolds has certain specialized uses. Flexibility provides versatility and thus alginate fiber systems are ideal for encouraging cells to recreate the tissue geometry in three dimensions. Scaffolds may be knitted, woven, nonwoven, braided, embroidered or a combination of these techniques. They may be modified to meet the different cell requirements by, say, altering the fiber diameter, length or even the extreme step of modifying the polymer. 

The yam bending or straightening shown in Figure 9 is in many cases the most significant deformation mode in many textiles. It is the most influential mode in knitted fabrics because of the knit loop geometry. Straightening also occurs to a lesser extent in woven and braided fabrics depending on the amount of crimp or yam undulation present in the fabric stmcture. 

Three-dimensional textile geometries are defined as spatial fabrics (areas of second order in space). Without previous forming steps, they either build up a volume or enclose the volume (for example, contoured woven fabrics, circular braiding) (Busgen, 1993).
