The invention belongs to the technical field of textiles, and particularly relates to lyocell fiber covering yarn lining cloth and a manufacturing method thereof. The lyocell fiber core-spun yarn lining cloth is formed by weaving lyocell short fiber yarn wrapped with low-melting-point chemical fiber filaments, the core yarn is 100% lyocell short fiber yarn with 10-80 English counts, the lyocell short fiber yarn is wrapped with 30-200 D low-melting-point chemical fiber filaments, the melting point of the low-melting-point chemical fiber filaments ranges from 110 DEG C to 180 DEG C, the types of the low-melting-point chemical fiber filaments comprise a single-component full-melting type or a double-component skin-core type, and the low-melting-point chemical fiber filaments are made of polyester fibers. The lining cloth weave is woven fabric, knitted fabric and the like. The lyocell fiber covering yarn lining cloth does not need to be coated with glue, is soft in hand feeling, does not contain formaldehyde, can be tightly attached to a garment material only through high-temperature hot pressing in the using process, can keep the lining part flat, is not prone to wrinkling and falling off, and is suitable for being used as various garment accessories.

The invention provides a process method for inhibiting generation of micro-nano structure machining burrs, and relates to the field of workpiece micro-machining. According to the process method for inhibiting the generation of the processing burrs, a UV light-cured film is used as a protective layer, and the generation of the burrs is inhibited by combining solution cleaning and plasma cleaning. The method specifically comprises the steps that a UV light curing protection layer is prepared through a UV light curing and hot drying method before machining, and lateral plastic flowing of a boundary material of a machined part is restrained through the protection layer, so that burrs are only generated on the surface of the protection layer material; according to a processing material and the size of the micro-nano structure, the thickness of the protective layer is controlled through the spin-coating rotating speed, and the hardness of the protective layer is regulated and controlled by controlling the photocuring and hot drying time; and then, processing of the micro-nano structure is achieved through ultra-precision cutting, finally, a solution and plasma combined two-step cleaning method is used for removing photoresist and removing the protective layer, a burr-free smooth surface structure is obtained, and therefore burr inhibition suitable for the cutting process of the micro-nano structures of various materials is achieved.
