摘要:
The present invention provides for treating textiles with a composition comprising the reaction product of a) an oxirane or oxetane compound comprising at least two oxirane or oxetane groups; and b) an amino silane having the formula: N(H)(R 1 )R 2 Si(OR 3 ) 3-a-b-c (OR 4 ) a (R 5 Si(OR 6 ) d (R 7 ) e ) b R 8 c with R 1 is chosen from the group consisting of H or a monovalent hydrocarbon radical containing one to 20 carbon atoms; R 2 and R 5 are independently selected from a group consisting of oxygen or a divalent linear or branched hydrocarbon radical consisting of 1-60 carbons; R 4 is a hydrocarbon radical that contains 3 to 200 carbon atoms; R 3 , R 6 , R 7 , and R 8 and are each independently selected from the group of monovalent linear or branched hydrocarbon radicals having from 1 to 200 carbon atoms; the subscript b is zero or a positive number and has a value ranging from 0 to 3; the subscripts a, and c are zero or positive and have a value ranging from 0 to 3 subject to the limitation that (a + b + c) ≤ 3; the subscripts d and e are zero or positive and have a value ranging from 0 to 3 subject to the limitation that (d + e) ≤ 3, to impart an enhanced response to water.

The invention relates to a textile web made of aramid fibers having a finish, wherein the finish comprises carbonic acid polyester. The invention further relates to the use of the textile web for producing a penetration-proof article, such as a splinter protection mat, a bullet-proof vest, a flak jacket, a stab-proof vest, or a combination of at least two of the mentioned articles.
摘要:
The invention provides a method for forming a hydrophobic coating on the surface of a solid substrate, the method comprising: a) applying to the surface a composition comprising hydrophobic nano-sized particles, wherein at least some of the hydrophobic nano-sized particles are particles having at least one fluoro-substituted non-polar group on the surface of the particle; and b) curing the applied composition to form a coating bound to the surface, wherein the nano-sized particles provide the surface of the coating with nano-scale roughness. The method can be used to form a hydrophobic and lyophobic coating on the surface of a textile.

A random mat including carbon fibers and a thermoplastic resin, wherein a pressure applied when molding can be reduced and high mechanical strength is obtained when a shaped product of fiber reinforced composite material is formed, is provided. A random mat including carbon fibers having an average fiber length of from 3 mm to 100 mm and a thermoplastic resin, wherein a fiber areal weight of the carbon fibers is from 25 to 10,000 g/m 2 , a proportion of carbon fiber bundles (A) constituted by single carbon filaments of a critical single fiber number or more defined by the formula (1) to the total amount of fibers in the random mat is from 40 to 99 Vol%, and an average number (N) of fibers in the carbon fiber bundles (A) satisfies the formula (2): Critical single fiber number = 600 / D 2.0 × 10 5 / D 2 ‰¤ N
摘要:
Des polyesters d'acide carbonique biodégradables solubles dans l'eau ont la formule générale (I), dans laquelle R1 désigne une résidu alkyle à chaîne droite ou ramifiée, saturé ou monosaturé ayant 6 à 22 atomes de C; R2 désigne hydrogène ou des groupes méthyles, R3 désigne hydrogène ou le groupe (1), dans lequel n est un nombre entier compris entre 0 et 10; m est un nombre entier compris entre 5 et 16, et z est un nombre entier compris entre 1 et 3. Ces polyesters sont utilisés comme agents de préparation et de lubrification de fibres synthétiques.
