摘要:
A retroreflective garment constructed of flame resistant fabric. The garment is light-weight and can be single or double layered. Garments that can be constructed of flame resistant fabric with retroreflective elements applied thereon include garments such as, for example, shirts, pants, coveralls, jumpsuits, jackets, gloves, hats, etc. The flame resistant fabric has a coefficient of retroreflection of about 10 to about 500 candelas per lux per square meter. In addition, the retroreflective elements cover at least about 5 percent of the outer surface of the flame resistant fabric.

摘要:
A retroreflective article (100, 200, 300) that has a retroreflective layer (120, 220, 320) that includes optical elements (121, 221, 321) and a specularly reflective layer (122, 222, 322), and a binder layer (110, 210, 310), that is the reaction product of an epoxy resin and polymer that has a silicon-containing, cross-linkable, terminal, functional groups. Retroreflective articles of this construction can demonstrate good abrasion resistance and laundering durability.
摘要:
A coated abrasive article comprising (a) a porous backing having a front side and a back side; (b) in direct contact with the porous backing, a make coat formed from a composition comprising a radiation curable adhesive applied over the front side of the backing; (c) a multiplicity of abrasive grits bonded by the make coat to the front side of the backing; and (d) a size coat overlying both the abrasive grits and the make coat. The invention also involves several methods for preparing the coated abrasive article. In all of these methods, a radiation curable make coat precursor is applied directly to the front side of the porous backing. No treatment coat is required to seal the backing prior to application of the make coat precursor.
摘要:
The present invention provides a backing for a coated abrasive article. The backing of the invention addresses problems of previously known backings for coated abrasives. The backings used previously are typically made of paper, cloth, vulcanized fiber, or combination thereof. Many of these materials do not exhibit sufficient strength, flexibility, impact resistance, and resistance to humidity extremes. High humidity, in particular, may cause premature curling of these backings, rendering the coated abrasive disc inoperable. The backing of the present invention includes a tough, heat resistant, thermoplastic binder material, and an effective amount of a fibrous reinforcing material distributed throughout the thermoplastic binder material. The tough, heat resistant, thermoplastic binder material and the fibrous reinforcing material together form a hardened composition that will not substantilly deform or disintegrate during use.

This invention relates to a cleaning device comprising a cleaning composition and a substrate. The cleaning composition comprises an absorbent particulate, a binding agent, and optionally, a thickening agent. The cleaning composition may be applied to a substrate, such as a textile substrate, by applying the composition to at least one portion of the surface of the substrate or by incorporating the composition throughout the substrate. The absorbent particulate generally exhibits a high affinity for particles, color, grease, oil, and other staining materials and is a soft material which allows for gentle cleaning of most surfaces without detrimentally abrading and scratching soiled surfaces. The absorbent particulate also serves as an indicator providing a visual cue of its cleaning efficacy and may be used in either a wet or dry state.

This invention relates to a friction material and, more particularly, to a wet friction material capable of being manufactured using conventional paper- making processes. Long fibers are used to form a wet-laid homogeneous skeletal matrix, which is reinforced by dispersing particulate materials throughout the friction matrix and throughout the matrix binder, specifically at the interstices of adjacent fibers, to significantly increase the shear strength of the material while having a near negligible effect on fluid flow through the material.
摘要:
A waterproof-finished fabric and a sealing tape for a waterproof-finished fabric which have a waterproofing layer and, laminated thereon, a resin composition containing spherical particles having a specific particle diameter; and a piece of waterproof clothing using the fabric or the sealing tape. The clothing has good waterproofing properties, is comfortable to wear, is lightweight and further can be manufactured at a low cost.
摘要:
The present invention relates to a friction material comprising a fibrous base material primary layer of less fibrillated aramid fibers, synthetic graphite and at least one filler material, and a secondary layer of a mixture of carbon particles and at least one retention aid coated on at least one surface of the primary layer. In certain embodiments, the fibrous base material is impregnated with a phenolic or phenolic-based resin material, including, for example, a mixture of a phenolic resin and a silicone resin to form a friction material having high heat resistance and high friction durability characteristics.
