摘要： A non-woven fabric is provided which includes a three-dimensional array of fibers. The three-dimensional array of fibers includes an array of standing fibers extending perpendicular to a plane of the non-woven fabric and attached to a base substrate, where the base substrate is one or more of an expendable film substrate, a metal base substrate, or a mandrel substrate. Further, the three-dimensional array of fibers includes multiple layers of non-woven parallel fibers running parallel to the plane of the non-woven fiber in between the array of standing fibers in a defined pattern of fiber layer orientations. In implementation, the array of standing fibers are grown to extend from the base substrate using laser-assisted chemical vapor deposition (LCVD).

摘要： The invention provides a flame-retardant and windproof wadding, which is obtained by using a polymer containing an imide ring as a base material and interlacing and compounding it with at least one polyester fiber in a spinning stage; and a preparation method and special equipment thereof. The characteristics and advantages of the present invention are as follows: the flame-retardant and windproof wadding provided by the present invention uses polyimide fiber as the base material and various fibers; through the adjustment of the preparation method and special equipment, the improvement of the windproof, thermal insulation and flame-retardant effect of the wadding is finally realized; and the same time, various fibers in the wadding are highly mixed, forming a homogeneous, moderately cross-linked and fluffy mixed structure, which can greatly reduce the probability of falling off of the layered structure in the traditional process.

摘要： A process for forming multi-layer fibrous web with good absorbent capacity and absorbent rate is disclosed. The multi-layer fibrous web can be used as absorbent articles, including wiping products, such as industrial wipers, food service wipers, and the like. The multi-layer fibrous web includes a first layer and a second layer, as well as a crossover zone, that has a capillary pressure between the capillary pressure of the first layer and the capillary pressure of the second layer.
