While increasing the tear strength of the product, the method realizes and simplifies the process of making both the absorbent material and the hygiene pad utilizing the absorbent material on the same manufacturing line, and reduces the cost of making the absorbent pads. The absorbent core made by applying the method of the current invention has a new structure formed by super absorbent polymers and wood pulp fibers, wherein the structure enables the super absorbent polymers to be evenly distributed in between the wood pulp fibers.Type: GrantFiled: August 16, 2012Date of Patent: January 22, 2019Assignee: Beijing Beishute Maternity & Child Articles Co., Ltd.Inventor: Qiuhong Li

Patent number: 10149749Abstract: A structure of aligned (e.g., radially and/or polygonally aligned) fibers, and systems and methods for producing and using the same. One or more structures provided may be created using an apparatus that includes one or more first electrodes that define an area and/or partially circumscribe an area. For example, a single first electrode may enclose the area, or a plurality of first electrode(s) may be positioned on at least a portion of the perimeter of the area. A second electrode is positioned within the area. Electrodes with rounded (e.g., convex) surfaces may be arranged in an array, and a fibrous structure created using such electrodes may include an array of wells at positions corresponding to the positions of the electrodes.Type: GrantFiled: June 16, 2011Date of Patent: December 11, 2018Assignee: Washington UniversityInventors: Matthew R. MacEwan, Jingwei Xie, Zack Ray, Younan Xia

Patent number: 10138582Abstract: A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.Type: GrantFiled: December 2, 2015Date of Patent: November 27, 2018Assignee: NIKE, Inc.Inventors: Bhupesh Dua, Karen Hawkinson

Patent number: 10046352Abstract: A contact nozzle for coating an elastic strand with an adhesive. Air is discharged at the adhesive in contact with the strand, causing the adhesive to spread around the periphery of the strand. The air assists with release of the adhesive from the nozzle and also cleans the nozzle to discourage adhesive build-up on the nozzle.Type: GrantFiled: September 28, 2015Date of Patent: August 14, 2018Assignee: Nordson CorporationInventors: Joel E. Saine, Charles P. Ganzer
