흡수성 구조체 및 제조 방법이 개시된다. 일 실시예에서, 흡수성 구조체는 제1 층, 제2 층, 및 제1 층과 제2 층 사이의 입자 및 접착제의 혼합물을 포함할 수 있고, 여기서 입자는 400gsm 초과 및 600gsm 미만으로 배치되고, 접착제는 입자의 중량의 4중량% 초과 및 6중량% 미만으로 배치되고, 여기서 접착제는, 메시 네트워크 내에 고정된 입자를 갖는 네트워크 접착 필라멘트를 포함하는 3차원 메시 네트워크를 형성하고, 네트워크 접착 필라멘트는 네트워크 접착 필라멘트 및 입자에 의해 정의된 실질적으로 3차원 공간 전체에 걸쳐 연장되며, 구조체는 패드 균일성 시험 방법에 따라, 34.5 이하의 그레이 레벨 % 분산 계수 값(GL %COV)을 갖는다. Absorbent structures and methods of manufacture are disclosed. In one embodiment, an absorbent structure may comprise a first layer, a second layer, and a mixture of particles and adhesive between the first layer and the second layer, wherein the particles are disposed at greater than 400 gsm and less than 600 gsm, wherein the adhesive is disposed at greater than 4% and less than 6%, by weight, of the weight of the particles, wherein the adhesive forms a three-dimensional mesh network comprising network adhesive filaments with the particles immobilized within the mesh network, and the network adhesive filaments extending substantially throughout a three-dimensional space defined by the network adhesive filaments and the particles, the structure having a Gray Level % Coefficient of Variability value (GL % COV) of less than or equal to 34.5, according to the Pad Uniformity Test Method.
