A thermoplastic prepreg includes a mat, web, or fabric of fibers and hollow glass microspheres that are positioned atop the mat, web, or fabric of fibers or dispersed therein. The thermoplastic prepreg also includes a thermoplastic polymer that is fully impregnated through the mat, web, or fabric of fibers and the hollow glass microspheres so that the thermoplastic prepreg has a void content of less than 3% by volume of the thermoplastic prepreg. The thermoplastic material is polymerized monomers and oligomers in which greater than 90% by weight of the monomers or oligomers react to form the thermoplastic material.

A protein surface layer is formed on a surface of a base fiber comprising a natural protein fiber including silk or a synthetic protein fiber including Chinon. The protein surface layer is divided in a plurality of particles by cracks. The resultant fibers with the protein surface layer divided in particles by cracks affords bulky textile products with an improved texture.

An improved wet processing method for producing improved terry fabrics is provided. Woven fabric is treated based on enzymatic treatment process including de-sizing using optimized dosage of predetermined de-sizing ingredients, washed and bio-washed using optimized dosage of bio-washing ingredients. Enzyme treated fabric is pre-treated and subjected to hot air beat-up process comprising mechanically treating pre-treated fabric with optimized hot air beat-up parameters. Air is blown onto pre-treated fabric from both directions for predetermined duration and at predetermined frequency causing to and fro movement of fabric in tumbling chambers of tumbling machine resulting in an instantaneous impact produced on every pile loop of pre-treated fabric such that fibers rearrange in a path of least resistance to produce relaxed, open and aligned fiber structure in the fabric. Mechanically treated hot air-beaten up fabric is dyed and includes finishing the dyed fabric with softener and subjected to tumbling using optimized finishing parameters.

According to one embodiment, a system for manufacturing a fully impregnated thermoplastic prepreg includes a mechanism for moving a fabric or mat and a drying mechanism that removes residual moisture from at least one surface of the fabric or mat. The system also includes a resin application mechanism that applies a reactive resin to the fabric or mat and a press mechanism that presses the coated fabric or mat to ensure that the resin fully saturates the fabric or mat. The system further includes a curing oven through which the coated fabric or mat is moved to polymerize the resin and thereby form a thermoplastic polymer so that upon exiting the oven, the fabric or mat is fully impregnated with the thermoplastic polymer. During at least a portion of the process, humidity in the vicinity of the coated fabric or mat is maintained at substantially zero.

The invention relates to a method of fabricating a conductive fabric by vapor phase polymerization, a multi-pressure sensor for a fiber type, and a multi-pressure measuring method employing the multi-pressure sensor. The method of fabricating a conductive fabric by vapor phase polymerization provides a conductive fabric having a resistance value which changes depending on pressure applied by a user. The multi-pressure measuring method employing the multi-pressure sensor has high resistance to moisture and repeated loading, is manufactured with lower costs than existing pressure sensors, is capable of measuring both dynamic and static pressures using a principle of a piezo-resistive sensor, has a simple circuit configuration, and is strong against a high-frequency disturbance.
