The adhesive thread drawing processes include the steps of feeding, mixing and stirring, first drying, hot melt extrusion, first cooling, stretch extension, second cooling, winding-strands-into-roll, and second drying. The threads made by the processes are woven into fabric which has a certain level of stickiness so as to be attached onto objects without using glue and adhesive, and the fabric is flat and neat when it is attached to an object.

A method for manufacturing a composite fabric includes the steps of feeding, mixing and stirring, first drying, hot melt extrusion, first cooling, stretch extension, second cooling, winding-strands-into-roll, second drying, and weaving. The composite fabric is composed of multiple first threads and multiple second threads which are woven to the first threads. The first threads and the second threads are respectively reflective threads and glowing threads so that the composite fabric includes both features of light reflection and glowing in dark.

A gas diffusion layer for proton exchange membrane fuel cell and preparation method thereof are provided. The preparation method is to papermake and dry carbon fiber suspension mainly composed of a fibrous binder, water, a dispersant and carbon fibers with different aspect ratios to obtain a carbon fiber base paper, and then carbonize and graphitize under the protection of nitrogen or inert gas to obtain a gas diffusion layer for proton exchange membrane fuel cell; where the fibrous binder is a composite fiber or a blend fiber composed of a phenolic resin and other resin; where the prepared gas diffusion layer for proton exchange membrane fuel cell has a pore gradient, and the layer with the smallest pore size is an intrinsic microporous layer.

A polymer composition includes a low ethylene random copolymer that can be used to form a meltspun or spunbond article at high spinning velocities. The polymer composition has a low xylene soluble content, a high crystallinity, or both, while having reduced spin-break at high spinning velocities. The polymer composition also exhibits good fiber tenacity and fabric softness.

A method for making nonwoven fabric. The nonwoven fabric can include three-dimensional features that define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property. The nonwoven further has a plurality of apertures, wherein at least a portion of the aperture abuts at least one of the first region and the second region of the microzone.

A system and method for forming non-woven fibers includes an extruder for melting a substance, a nozzle on an end of the extruder for outputting the melted substance, and a gas source in fluid communication with the nozzle. The nozzle may be configured to output the substance in a melted form at atmospheric pressure proximate an output of the gas source. The system may be configured to output a gas stream at lower temperature.
