The physical properties of China 100% polyester cap interlining 300gsm are thickness, stretch, ironing temperature and pressure required for ironing.

　　1. Non-woven interlining and woven interlining have different degrees of thickness. China 100% polyester cap interlining 300gsm Like the fabric, the thickness is difficult to measure, and can only be judged by visual and sensory. Usually, the thickness of interlining is classified into three types: thin, medium and thick.

　　2. There are two kinds of elasticity in woven interlining, one is the elasticity of the interlining cloth woven with elastic yarn material, and the other is the degree of stretch due to the existence of gaps in the weaving of the two systems of warp and weft due to stretching; no The elasticity of the spun interlining is its own stretch.

　　3. China 100% polyester cap interlining 300gsm ironing temperature refers to the temperature at which the interlining viscose is heated and melted. Usually, China 100% polyester cap interlining 300gsm has two kinds of high temperature interlining and low temperature interlining.

　　4. The firmness of the 100% polyester cap interlining in China 300gsm on the fabric is related to the ironing temperature of the interlining, the pressure required for the interlining, and the length of the ironing time. Usually, the ironing pressure of the high-temperature lining is relatively large, and the ironing time is relatively long; on the contrary, the ironing pressure of the low-temperature lining is relatively small, and the ironing time is relatively short.
