Abstract
A starch composite for binding fibers includes starch particles which are first particles and second particles containing a hydrophobic material having an affinity for the starch particles, which are the first particles. The weight-average size of the second particles is less than the weight-average size of the first particles and the outer surfaces of the first particles are covered by the second particles.
Claims10
A starch composite for binding fibers, comprising:
- starch particles which are first particles;
- and
- second particles containing a hydrophobic material having an affinity for the starch particles, which are the first particles, wherein
- the weight-average size of the second particles is less than the weight-average size of the first particles and the outer surfaces of the first particles are covered by the second particles.
A starch composite for binding fibers, comprising:
- starch particles;
- and
- coat layers which are made of a hydrophobic material having an affinity for the starch particles and which coat the starch particles.
A fiber structure containing:
- cotton-like fibers;
- starch particles;
- and
- a hydrophobic material having an affinity for the starch particles, wherein
- the starch particles and the hydrophobic material are dispersed between the cotton-like fibers and the cotton-like fibers, the starch particles, and the hydrophobic material are bound.
A fiber structure-manufacturing apparatus comprising:
- a disintegration section disintegrating a supplied fiber feedstock to produce disintegrated matter;
- an incorporation section incorporating a starch composite having a surface covered by a hydrophobic material having an affinity for starch particles into the produced disintegrated matter;
- a fibrous web-forming section forming a fibrous web by accumulating a mixture containing the starch composite;
- and
- a fiber structure-forming section forming a fiber structure by heating and pressing the fibrous web.
