Properties Of Knitted Fabrics

Dispersion: In knitted fabrics, due to the breakage of a certain yarn, the coils and coils are separated from each other and lose the performance of interlocking. The larger the friction coefficient and bending stiffness of the yarn, the shorter the loop length, and the smaller the looseness of the knitted fabric.

Hemming: The performance of wrapping around the edge of knitted fabrics in a free state. This is caused by the bent yarn in the edge loop trying to straighten out. The thicker the yarn, the better the elasticity, the shorter the loop length, and the more obvious the hemming. Generally, double-sided knitted fabrics basically do not curl because the internal stress of the front and back stitches at the edge is roughly balanced.

Extensibility: The performance of knitted fabrics to elongate in size under external stretching. Because the loops can change shape and size, knitted fabrics have greater extensibility. Changing the organizational structure can reduce the extensibility of knitted fabrics.

Elasticity: The ability of a knitted fabric to return to its original size after the external force is removed. It depends on the yarn properties, loop length and knit weave.

Strength: The force (kg) that the knitted fabric can withstand when it breaks. Commonly used tensile and burst test methods to determine.

Snagging and pilling: When a knitted fabric encounters a rough object, the fiber or yarn will be hooked out, some coils will be tightened, and a loop of silk will be formed on the surface of the fabric, which is called snagging. The fabric is constantly subjected to friction during wearing and washing, and the fiber ends in the yarn are exposed to the surface of the fabric, forming fuzz, which is called fluff. If the fur is entangled with each other and kneaded into balls in the future wearing, it is called pilling. In addition to the use conditions, the factors that affect snagging and pilling mainly include raw material types, yarn structure, knitted fabric structure, and dyeing and finishing processing.
