A non-woven cloth applied to a motor vehicle interior trim, wherein uniformly distributed through-holes are formed on the non-woven cloth, the radius of the through-holes being 0.5-2mm and the distance between the tangent edges of two adjacent through-holes being 2-6mm. Through-holes are formed on the non-woven cloth and the through-holes play the role of sound and heat absorption; therefore, the non-woven cloth formed with through-holes not only has good sound-proofing and heat insulation effects, but also has excellent permeability.

PROCESS FOR HEALTH-PRESERVING HEMP FIBER AND SPECIAL HEALTH-PRESERVING ADDITIVE FOR JUTE FIBER USED THEREIN
A process for health-preserving hemp fiber is provided and includes the following steps: (1) spraying the prepared additive onto the hemp fiber, wherein the weight ratio of the additive and hemp fiber is 0.4-0.5; (2) introducing the treated hemp fiber in step (1) into the first health-preserving storehous and leaving it for 2-3 days; (3) taking out the improved hemp fiber in step (2) from the first health-preserving storehous, reversing the hemp fiber and placing it into the second health-preserving storehouse. After reaching a temperature close to 50-60°C, keeping it for 5-6 days in the health-preserving storehouse. The health-preserving process enables the additive to better penetrate into the inner core of the hemp fiber, thus effectively improving the hemp fiber spinnability. A special health-preserving additive used in the above health-preserving process is further provided. Said health-preserving additive improves the humidity and softness of the fiber, while ensuring the suitable whiteness thereof.
