Sizing composition and process for textile materials
Use for sizing textile materials with an aqueous sizing composition including at least one co-polymer obtained by the polymerization of at least one non-ionic monomer and/or one anionic monomer, and at least one monomer of formula (I): ##STR00001##
in which: R.sub.1 is an atom of hydrogen or a methyl radical; x=0 or 1; Z is a divalent grouping C(O)O, C(O)NH, or CH.sub.2; n is an integer between 1 and 250; R.sub.2 is a hydrogen atom or a carbonated radicalsaturated or unsaturated, possibly aromatic, linear, ramified or cyclicincluding from 1 to 30 carbon atoms and from 0 to 4 hetero-atoms chosen from the group including O, N and S.

VARIANT MALTOHEXAOSE-FORMING ALPHA-AMYLASE VARIANTS
Disclosed are compositions and methods relating to variant maltohexaose-forming alpha-amylases. The variant alpha-amylases are useful, for example, for starch liquefaction and saccharification, for cleaning starchy stains in laundry, dishwashing, and other applications, for textile processing (e.g., desizing), in animal feed for improving digestibility, and for baking and brewing.

Production method for high-low pile towel
The present invention falls within the field of textile products, and specifically provides a brand new production method for a high-low pile towel. The method breaks through the visual monotony of conventional towels and a traditional design method in which two or three adjacent conventional pile loops have a consistent pile loop height in conventional high-low pile towels, but uses a design method in which two or three adjacent pile loops have a inconsistent pile loop height for weaving, and at the same time uses a special dyeing and finishing treatment, whereby the dyed and finished product has a special visual effect, a strong visual impact, and a fluffy and soft hand feel, and the product therefrom has a high additional value without improving the coats, compared with the existing products. The method fills up a blank of high-low pile towels, and can be widely popularized and applied.

Coatings for the manufacture and application of polyhydroxyalkanoate medical devices
Biocompatible coatings and spin finishes that can be applied to polyhydroxyalkanoate (PHA) polymers, and medical devices made from PHA polymers, have been developed. The coatings impart good lubricity to PHA polymers, particularly to fibers and braids made from these materials, making the coatings ideal for use on medical devices such as PHA braided sutures. The spin finishes can be applied to PHA fibers to facilitate their manufacture, and also for their conversion to other products, including medical textiles. The spin finishes serve to protect multifilament fiber bundles, and keep them intact following extrusion, and also to impart lubricity to the fiber bundles and monofilament fibers so that they are not damaged in subsequent processing steps particularly in textile processing. The coating reduces tissue drag of, for example, braided sutures.

Method for manufacturing fastener stringer
A method for manufacturing a fastener stringer according to the present invention, include a dyeing step for dyeing a fastener stringer including an element row fixed to a side edge portion of a tape made of fiber, a dye cleaning step for removing excess dye from the fastener stringer, a water repellent treatment step for adhering a non-fluorine-based water repellent agent to the fastener stringer, and a pre-dyeing degreasing step for degreasing oil and fat adhered to the fastener stringer by a wet process.
Carbon fiber fabric cleaning and finishing
A process to clean carbon fiber fabric of a pre-applied sizing, while simultaneously activating or preparing the fabric to receive a polymer resin is described. The cleaning process and chemistry combines an enzymatic cleaning solution with an oxidizing agent. The enzymatic solution strips the fibers of lubricants, surfactants, and other chemicals of the sizing which might otherwise interfere with interfacial properties and bonding of the fabric to the matrix resin. The inclusion of an oxidizing agent concurrently adds hydroxyl groups to the surface of the fabric allowing for the grafting of organic copolymers to the surface of the fabric, the copolymer being chosen based upon the desired polymer resin. This process provides a customized finished carbon fiber fabric to bond to a specific polymer resin, without interference resulting from an inadequate fiber sizing chemistry. In this way, a customizable finished fabric may be manufactured.
