Catching Up

This week I will focus on issued patents.  Below is a summary of selected patents that have been recently issued in textile related classification codes:

Spunbond fibers and fabrics from polyolefin blends:  A polyolefin blend composition suitable for spunbond fiber or filament comprising a least one random propylene copolymer having a comonomer content of from 8 to 25 wt % with a crystalline melting point between 40° C. to about 110° C; and an isotactic polypropylene homopolymer with a crystalline melting point greater than or equal to 120° C. The blends of the present invention typically have a melt flow rate (MFR) of from 100 g/10 min to about 500 g/10 min.  Patent:  8728960.  Inventor:  Kacker and Cheng.  Assignee:  Exxonmobil Chemical Patents Inc.

Fabric with equal modulus in multiple directions:  A knit pattern for elastic fabric knitted with spandex with approximately equal modulus values in three directions. The three directions include a first reference direction, a second direction perpendicular to the first direction and a third direction offset by 45 degrees from the first direction and the second direction.  Patent:  8726700.  Inventor:  Waldman and Lazarus.  Global Trademarks LLC.

Article of apparel incorporating a zoned modifiable textile structure:  A garment is disclosed that includes zones with a textile having a structure that changes or is otherwise modified by a physical stimulus, such as the presence of water or a temperature change that modifies a property of the textile.  The invention involves an article of apparel having a first material and a second material. The first material exhibits a dimensional transformation upon exposure to a physical stimulus.  The second material remains substantially stable upon exposure to the physical stimulus.  A variety of physical stimuli, such as water or changes in temperature, may induce the dimensional transformation.  Patent:  8726414.  Inventor:  Baron.  Assignee:  Nike, Inc.

Shoe having a bridge mechanism:  A shoe with a sole where the outsoles are connected by a bridging mechanism instead of a solid piece.  Patent:  8726542.  Inventor:  Kim.  Assignee:  Ls Networks Corporation Limited

Clamp assembly and apparel containing same:  A clamp assembly for attaching together two items of clothing such as a glove and coat sleeve. The clamp assembly includes a circular band and a tubular resilient cover having a hollow body.  The clamp is positioned in the hollow and is encased on all sides by the resilient cover.  Patent:  8726417.  Inventor:  McLachlan.  Assignee:  E I Du Pont De Nemours And Company

Texturing device and method for texturing continuous yarns:  A texturing device for texturing at least one continuous filament yarn. The device has at least one nozzle core which can be charged with a fluid. The nozzle core includes a yarn channel and a fluid feed channel opening into the yarn channel with a radial component. The distance between the inlet opening and the fluid feed channel of the nozzle core is at most 12.5 mm.  Patent:  8726474.  Inventor:  Simmen.  Assignee:  Oerlikon Heberlein Temco Wattwil Ag

Punch data generating device and computer readable medium storing punch data generating program:  A device that generates punch data used in an embroiderable sewing machine for punch engraving a pattern on a workpiece by punching the punch needle through the work piece while moving the work piece is two directions.  The punch data generating device includes a data generator that generates the punch data so that when punch engraving a plurality of patterns, the patterns are sequentially punch engraved one by one.  Patent:  8733263.  Inventor:  Kawaguchi,  Assignee:  Brother Kogyo Kabushiki Kaisha

Use of tea-polyphenol and/or tea-pigment as dye and products thereof:  The use of tea-polyphenol and/or tea-pigment as a dye.  Specifically, it is a combination of tea-polyphenol, its oxidation product, and tea-pigment with a metal salt for dyeing human or animal hair.  The advantages include good dyeing fastness that is natural and bright, non-allergenic, non-mutagenic, and simple to use.  Patent:  8734531.  Inventor:  Hu and Lan.  Assignee:  Natural Medicine Institute Of Zhejiang Yangshengtang Co., Ltd.

Shoes, devices for shoes, and methods of using shoes:  A shoe with two hinged plates that sandwiches a spring that returns impact energy to the wearer. It is not exactly clear to me what the benefit is but the application is remarkably detailed and a lot of engineering effort went into this patent.  Patent:  8732983.  Inventor:  Goldston,  Assignee:  Athletic Propulsion Labs LLC

Sole structure comprising a fluid filled member with slots:  A sole structure comprising a fluid filled member and a plurality of slots. The slots are interconnected with each other and the sole structure to provide for increased fit, flexibility and stability.  Patent:  8732986.  Inventor:  Miner.  Assignee:  Nike, Inc.

Hygro materials for use in making yarns and fabrics:   A pile fabric is woven with cotton/PVA weft and warp yarns to produce terry fabrics. The fabric is then washed in warm water to dissolve the PVA fibers.  By dissolving the PVA fibers, a hollow air space is produced throughout the pile yarn.  By increasing the air space in the pile yarn, the resulting towels are softer and bulkier than standard cotton towels.  Patent:  8733075.  Inventor:  Mandawewala.  Assignee:

Azo dyes:  New azo dyes, and a process for their preparation, for use in dyeing or printing fibrous materials, to produce materials with brownish shades.  Patent:  8734534.  Inventor:  Meier,  Assignee:  Kemira Oyj.

Azo dyes:  The present invention relates to new azo dyes, a process for their preparation, and their use for dyeing or printing fibrous materials, to produce materials with brownish shades.  Sister patent to 8734534.  Patent:  8734532.  Inventor:  Meier,  Assignee:  Kemira Oyj.
