The physical properties of lining fabric include the thickness and elasticity of the lining fabric, the ironing temperature of the lining fabric, and the pressure required for ironing the lining fabric.
(1) Both non-woven and woven interlinings have varying degrees of thickness, and the thickness of interlinings, like fabrics, is difficult to measure and can only be judged visually and perceptually. Typically, interlinings are classified into three types: thin, medium, and thick.
(2) There are two types of elasticity in woven lining fabric: one is the elasticity inherent in the lining fabric woven from elastic yarn material, and the other is the stretch caused by the gaps in the warp and weft yarn weaving. The elasticity of non-woven lining fabric is the stretch inherent in the non-woven lining material itself.
(3) The ironing temperature of lining fabric refers to the temperature at which the adhesive of the lining fabric melts when heated. There are usually two types of lining fabrics: high-temperature lining fabric and low-temperature lining fabric.
(4) The firmness of lining fabric during ironing is related to the ironing temperature, the pressure required for ironing, and the length of ironing time. Generally, high-temperature lining fabric has a relatively high ironing pressure and a relatively long ironing time, while low-temperature lining fabric has a relatively low ironing pressure and a relatively short ironing time.
