The dry weight per unit area of the knitted fabric is an important indicator of the quality of the knitted fabric. It is expressed in terms of the weight per square meter of dry knitted fabric (g / m2), and the cut- Weigh the weight, and then to calculate the moisture content per unit area of dry weight.

The thickness of the knitted fabric depends on its organizational structure, coil length and yarn fineness and other factors, generally in the thickness direction of a few yarn diameter to represent, or to the yarn density to represent the most simple to measure the thickness of the fabric thickness Value. The thickness of the fabric, especially in double-sided ribs, is very important and has a close effect on the appearance of the fabric.

The disintegration of the knitted fabric refers to a phenomenon in which the yarn of the knitted fabric is broken or the coil is separated from the coil and the string is interrupted. When the yarn breaks, there are two cases in which the loops are dislodged from the broken yarns along the longitudinal lines. Some of the fabric loops are disengaged in the reverse direction, and the sinks of some fabrics are scattered in the forward direction. The dispersibility of the fabric is not only affected by the strength and appearance of the knitted fabric, the dissolution of the knitted fabric and its structure, the coefficient of yarn friction, the unfilled coefficient of the fabric and the bending stiffness of the yarn. , Large dispersion, yarn friction coefficient and the bending stiffness of the yarn, the dissipation of small.

Some of the tissues of the knitted fabric in the free state, the edge of the phenomenon of natural wrap, called curling, is due to the bending of the coil in the coil, with internal stress, trying to make the yarn stretch, The result of the elastic restoring force of the coil. The crimp is related to the knitted fabric structure, yarn elasticity, yarn fineness, bulkiness, density and yarn length. The direction of the elastic restoring force is the same in all directions of bending, the formation of the fabric from the edge of the cloth to the front of the fabric wrapping, and longitudinal to the back wrapping, rib or double-sided fabric, The curvature of the corresponding yarn is opposite, and the curl of the fabric is not obvious under the action of the elastic restoring force in the opposite direction. Curling edge to the edge of the whole pulp and other processes to solve, or change the cloth edge organization for improvement.

The elongation of the knitted fabric refers to the elongation characteristic of the knitted fabric when subjected to external force, which is related to the structure of the knitted fabric, the length of the coil, the nature and fineness of the yarn, and the deformation of the coil and the elongation of the yarn , The extensibility of the knitted fabric can be divided into one-way and two-way, unidirectional stretch when the fabric stretched in the direction of tension, and the vertical tension direction shrink. And the two-way stretch, the two sets of vertical tension, while the role of the fabric, for the two sides of the stretch, such as tension non-stop until the fabric deformation as the stretch yarn, and finally broken up, generally most of the knitted fabric Transverse extensibility is greater than the longitudinal, and some fabrics are nearly the same in transverse extensibility.

The elasticity of the knitted fabric refers to the ability of the knitted fabric to restore the original shape after the removal of the external force of the knitted fabric, which depends on the knitting fabric's structure, the elasticity of the yarn, the decrease in the coefficient of friction of the yarn, The elasticity increases within the prescribed range with the decrease in the uncoated coefficient of the knitted fabric.

Knitted fabric shrinkage refers to the knitted fabric in a certain state, such as processing or use process, the size of the cloth or into the length and width of the size change, compared to the rate of change, which can be obtained by the formula: Y = H1-H2 / H1 X 100% Y - Knitted fabric shrinkage H1 - Size of the knitted fabric before processing or use H2 - Size of the knitted fabric after processing or use.

In the course of the use of knitted fabric, such as the case of sharp or rough objects, contact with each other, the fibers or yarn in the fabric is hooked out of a phenomenon, hook silk and fabric structure, density, raw material properties , After finishing the relevant.

The pullover is the fabric in the wear and washing process by the friction, the fabric surface of the fiber end is pulled out, exposed to the surface of the fabric and the formation of hair, if these fluffy knitted fabric in the future use of the process, can not take off, Even intertwined together, known as pilling balls. There are many factors of the pulsating ball, mainly for the varieties of raw materials used for knitted fabrics, knitted fabric structure, dyeing and finishing conditions.

Punching phenomenon in the synthetic fiber fabric is more serious, can be reduced in the appropriate fiber strength, so that the ball can easily fall off, can improve the surface of the ragged ball situation, with resin processing cloth, can also improve the ragged ball.
