  • Patent number: 10407538
    Abstract: A low chromatic aberration polyester different-shrinkage composite yarn is made of polyester POY yarn and polyester FDY composite yarn. The polyester POY yarn and polyester FDY yarn is obtained by spinning the polyester solution, the rupture strength of the low color polyester different-shrinkage composite yarn is ?1.9 cN/dtex, the elongation at break is 30.0±5.0%, the crimp shrinkage is 2.50±3.0%, the network degree is 20±5/m, the color difference ?E is less than 0.200. In the invention, the magnesium ethylene glycol is relatively mild, the thermal degradation coefficient is small, the oligomers in the polymerization process is reduced, and the oligomers in the dissolution process are further reduced, so that the appearance of stains and streaks reduces during the dyeing and post-processing heat setting of the polyester fiber, which ensures the fiber's leveling and rubbing fastness.

  • Patent number: 10370782
    Abstract: The present invention is directed toward an article of apparel formed of a textile having a knit structure (e.g., a circular knit structure) including a base strand and an effect strand. The base strand is inelastic. The effect strand, while inelastic, is modified to be resilient. The base strands are inserted at selected course locations within the knit structure. With this configuration, the knit structure possesses stretch and recovery properties. The resulting knit fabric may be utilized to make underwear (e.g., socks), top-weight garments (e.g., T-shirts), etc.

  • Patent number: 10009335
    Abstract: Techniques are disclosed for using a global unified session identifier across data centers. Upon creating an initial session in the data center for a user first accessing the data center, a session identifier is generated for the user session. Because the initial session is the first session created for that user, the initial session identifier is designated as the global unified session identifier for all sessions that may be created for the user in other data centers within the enterprise network. Data centers may then map the global unified session identifiers to locally generated session identifiers for the user. A global unified session identifier enables various user session actions to be performed globally across the data centers, including global logout, global session termination, global session updates, and/or the like. A global unified session identifier prevents the risk of collision that can occur between randomly generated numbers of different data centers.

  • Patent number: 9889607
    Abstract: A three-dimensional printer effects color changes in an extrudate using a color-application unit applying a colorant to the interior of a filament before it is melted within an extruder. Specifically, the color-application unit may receive a filament (or portions thereof) having an exposed interior surface, where color applicators are actuated to apply one or more colors to the interior surface of the filament in order to modify the extruded color. The filament may then be coupled, collapsed, or otherwise closed about the interior surface, e.g., by a mechanical coupler, to substantially enclose the interior surface of the filament, which is then fed to the extruder for fabricating a colored object in a three-dimensional fabrication process. By enclosing the colored surface within the filament before melting for extrusion, transition effects of a color change can be mitigated and transition time for a substantially complete change in color can be significantly reduced.

    Abstract: An anti-counterfeiting fiber, anti-counterfeiting paper containing the anti-counterfeiting fiber, and manufacture method thereof. The anti-counterfeiting fiber is a slice or part of a slice cut along a cross-section of a strip-shaped fiber, wherein the strip-shaped fiber includes a specific structure along the length direction providing anti-counterfeiting characteristics. Structures manufactured using the principles of the process have better orientation than structures manufactured using conventional processes for manufacturing anti-counterfeiting fiber during the paper manufacturing process and can form more unique visual characteristics.

  • Publication number: 20130202887
    Abstract: A method for encasing a body of an exhaust gas system with a housing which is wound around the body. Using a winding method, the body is placed in a loop formed by a belt-shaped conveyor element that can be driven in a conveyor device, wherein the conveyor element is seated against the outer casing face at a wrapping angle u of at least 270 degrees. Starting with a first edge, the metal strip is then introduced in a conveyor device between the body and the conveyor element, is drawn into the gap between the body and the conveyor element and is bent around the body until the body is encased at least twice by the metal strip.

  • Patent number: 8408219
    Abstract: Dental floss products are provided which include a unitary tape of ultra-high molar mass polyethylene having an intrinsic viscosity of at least 5 dl/g, as measured in decalin at 135° C., the tape having a thickness of about 0.02-0.1 mm and a width of about 0.25-6 mm, and a tensile strength of at least 1.8 GPa. The dental floss products have very high mechanical, especially tensile strength, and show high resistance to tearing and has a low coefficient of friction. The tape can be inserted between teeth tightly together without breaking. A further advantage of the dental tape products is that most of the initial strength during flossing is retained, even if the tape separates into filaments. Processes for making a unitary tape suitable for use in a dental floss product are also provided.

  • Publication number: 20130040121
    Abstract: Thermally expandable crimped hollow fibers having expandable regions interconnected with crimped portions are provided. The crimped hollow fibers may be formed from any hollow polymer fiber that is capable of being crimped and is reactive to heat. Pressure, such as from two opposed mating crimping dies, is applied to portions of a hollow polymer fiber to compress or crimp portions of the fiber, thereby leaving uncrimped or expandable regions containing an expandable substance. In use, the crimped hollow fibers may be contacted with cellulose fibers in the wet-end section of the paper-making process and the resulting mixture formed into a web of entangled fibers. Heat from the dryer section expands the expandable substance in the expandable portion of the crimped hollow fiber to bulk the thus formed paper product. The crimped hollow fibers are especially useful in papers having a basis weight from about 20 to about 200 gsm.

    Abstract: Disclosed is a chromium-free rust-inhibitive surface treatment agent to form a siliceous film that rarely cracks or peels off and yields an excellent rust-inhibitive performance on zinc surfaces of a metal part. The chromium-free rust-inhibitive surface treatment agent is an alcoholic solution of alkoxysilane oligomer having weight-averaged molecular weight of 1,000 to 10,000, and 2.5 to 15% of silicon in molecules of the alkoxysilane oligomer has been replaced with titanium. To prepare partly titanium-replaced alkoxysilane oligomer, titanium compound, in which about a half of alkoxy groups in titanium tetraalkoxide has been chelated, is reacted with tetraalkoxysilane monomer or alkoxysilane oligomer in the alcoholic solution.
