摘要:
Value-added compositions such as mulches, insulation, and animal bedding may be produced from cotton waste. These compositions are formed from mixtures of at least two cellulosic, biofiber components, wherein one or both of the components are fiberized. The compositions of this invention include mixtures of: a. a first cellulosic component of cotton byproducts, and b. a second cellulosic component which is visible to the naked eye, and which includes hay, grass, kenaf, straw, plant residue remaining following the harvest of crops such as cereal grains, rice, soybeans, and grass seed, wood, sawdust, wood pulp, paper, or mixtures of any of the above, wherein one or both of the first or second cellulosic component are fiberized and the fibers of the fiberized component are intermixed with and entangled about the other component in a 3-dimensional matrix.
摘要:
A method for making a hydraulically applied mulch using a natural biofiber material preferably comprising of 100% cotton byproduct or a mixture of cotton byproducts and other biomaterials selected such as, hay, grass, kenaf, straw, coconut, bamboo, hemp, bagasse and plant residue (cereal grains, rice, soybeans, grass seed, wood, sawdust, wood pulp, paper, or mixtures thereof). These fibers bear a natural waxy coating. The method includes the optional step of introducing the shredded biofiber composition into a first steaming chamber to stem the biofiber composition, followed by shredding the biofiber composition, and then introducing the shredded biofiber composition into a second steaming chamber to steam, break down and create porosity in the waxy coating of the fibers causing the fibers to become more hydrophilic. The biofibers are steamed followed by drying causing them to curl or physically deform. The shredded and steamed biofiber composition is then mixed to entangle the fibers, and the shredded, mixed and steamed biofiber composition is introduced into a drying chamber for drying, the resulting composition is then cooled and packaged, ready for mixing with water and spray application. The shredded, steamed and dried composition promotes entanglement of the fibers in a 3-dimensional matrix suitable for use as hydraulically applied mulch, and binding agents (tackifiers), dyes, rewetting agents, activators, and other additives may be added as desired.
摘要:
A roll (25) of woven fabric (30) having a length greater than the diameter thereof wherein the diameter (28) is substantially the same across said length of the roll. An assembly (50) operable with the tucking units of the picking (51) and receiving (52) ends of a weaving loom (53) for producing woven fabrics (30) comprises plate means (74) attached to the loom; main drive block means (76) connected to a harness (60) of the loom; operating rod means (78), having first and second ends (92, 95) and attached to the main drive block means at the first end (92) and pivotally mounted to an upper surface of the plate means at the second end (95); lifter means (80) connected to the operating rod means, proximal to the second end, for lifting the weft end gripper (70) of the loom; and means for selectively engaging (82) the weft end gripper, operatively associated with the operating rod means, whereby the weft end gripper positions consecutive pick lines (32) in an alternating fashion, allowing every other one to be tucked into the selvage of the fabric, while adjacent pick lines are untucked. A method for producing woven fabrics (30) having a tucked-untucked selvage comprising providing an assembly (50) at the picking (51) and receiving (52) ends of a weaving loom (53), operable with the weft end grippers (70) of the loom; attaching the assembly to a harness (60) of the weaving loom; and operating the assembly so that the weft end grippers move every other weft yarn (32) out of reach of the tucking needles of the loom.
摘要:
An X-ray fluorescence measurement device comprises an X-ray source and a sample window for allowing X-rays from the X-ray source reach a sample. A filter arrangement between the X-ray source and the sample window includes a first filter layer comprising a first filtering element and a second filter layer including a second filtering element. The atomic number of the second filtering element is greater than the atomic number of the first filtering element. The first filter layer is between the X-ray source and the second filter layer.
