METHOD FOR PROCESSING CARBON FIBER BUNDLE
Disclosed is a method for processing a carbon fiber bundle, which can adjust bundling property, winding property and wear resistance of sizing fibers. The method includes following steps: (i) coating a sizing agent on at least one carbon fiber bundle, in which the sizing agent includes a thermoplastic resin; (ii) drying the carbon fiber bundle by hot air; and (iii) heating the carbon fiber bundle by an infrared light, in which a heating temperature of the heating is equal to or higher than a melting point of the thermoplastic resin.
SOLID-STATE METHOD FOR TREATING POLYAMIDE AND POLYESTER ARTICLES
Solid-state branching and/or crosslinking of aliphatic polyamide or polyester articles is achieved using a topical approach. A surface of the article is coated with a composition that includes a polyene and a free radical initiator. The article and applied coating are then heated to induce branching and/or crosslinking in the polyamide or polyester. This is performed below the crystalline melting temperature of the polyamide or polyester, or in the case of a fabric, below the melting temperature of the fibers in the fabric. Fabrics treated in this manner exhibit reduced or even no dripping in vertical flame tests.
Aqueous Composition Comprising Multi-Stage Latex Polymer Particles
An aqueous composition including multi-stage latex polymer particles is provided. The multi-stage latex polymer particles include (A) a first-stage polymer containing (i) an ethylenically unsaturated acid monomer with two carboxylic acid groups and (ii) a first vinyl monomer, and (B) a second-stage polymer containing (i) an ethylenically unsaturated monomer with an epoxy group and (ii) a second vinyl monomer. An article including a nonwoven textile impregnated with the aqueous composition is also provided.

Surface modifying agents, modified materials and methods
The present invention relates to surface modifying agents for polymeric and/or textile materials, methods of making and/or using a surface modifying agent to modify and functionalize polymeric and/or textile materials, and/or methods of using surface modified or functionalized polymeric and textile materials, and/or products using or incorporating surface modified or functionalized polymeric and textile materials. For example, the surface modifying agent in precursor form can be styrene sulfonyl azide monomer, polymer or copolymer capable of undergoing a chemical reaction in the presence of heat or light to form one or more styrene sulfonated nitrene monomers, polymers or copolymers, which are capable of chemically reacting with the surface of a polymeric or textile material to endow a specific or desired chemical surface functionality to the surface of a polymeric or textile material. Furthermore, the present invention is possibly preferably directed to a surface modifying agent which comprises a styrene sulfonated nitrene monomer, polymer or polymer containing one or more nitrene functional groups, which are capable of chemically reacting via an insertion reaction into one or more carbon-hydrogen bonds on the surface of a polymeric or textile material in order to chemically attach a specific or desired chemical functionality to the surface of a polymeric or textile material.

Moisture control fabrics
The present disclosure provides articles of manufacture with improved moisture control as well as methods of making such articles. In some embodiments, provided herein the article has a fabric with an outer hydrophobic surface and an inner surface with hydrophobic and hydrophilic regions where the hydrophilic regions can form a pattern, allowing moisture to collect and move through the pattern, and the hydrophobic regions prevent the whole inner surface from becoming moist and the outer hydrophobic regions does not show moisture. The fabric may be used to make garments. The entire inner surface of the garment may be patterned with hydrophilic patterns for partial absorption, and the entire outer surface of the garment is hydrophobic, thereby preventing perspiration from being seen from outside of the garment. Further provided herein are methods of making fabrics with improved moisture control including by printing or knitting.
