专利汇可以提供Glass fibers coated with a size containing starch esters of isoalkanoic acids专利检索,专利查询,专利分析的服务。并且A size for lubricating fibers, including glass fibers, which is a water dispersion of a solid unctuous material, as for example a solid wax, fat, or gelled or otherwise solidified oil, and a starch ester of an isoalkanoic acid having from 4 to 6 carbon atoms and/or a substituted alkanoic acid having from 4 to 6 carbon atoms. The wax may be an animal, vegetable, mineral, or synthetic wax which is unctuous and insoluble in water. The oils can be gelled by adding any gelling agent, and preferably a thixotropic gelling agent to the oil. The starch esters are only partially cooked so that unburst starch granules are retained, and this dispersion is intimately mixed with the unctuous solid emulsified particles. Other ingredients such as cationic lubricants, coloring matter, bactericides, waxes having particular characteristics, etc. can be added to provide their separate functions. The combination of the above defined partially burst starch granules of esterified starch, and the emulsified particles of the solid unctuous material have very low migration from coated glass fibers, and when dried, provide low tensions when pulled over guide surfaces.,下面是Glass fibers coated with a size containing starch esters of isoalkanoic acids专利的具体信息内容。

1. GLASS FIBERS HAVING AN AQUEOUS COATING THEREON CONSISTING ESSENTIALLY OF SOLUBILIZED STARCH; UNCTUOUS MATERIAL FROM THE GROUP CONSISING OF VEGETABLE WAXES, ANIMAL WAXES, MMINERAL WAXES, SUNTHETIC WAXES, FATS AND GELLED OIL; AND AN EFFECTIVE AMOUNT OF SWOLLETN BUT UNBURST STARCH GRANULES MODIFIED BY ESTERS OF AN ISOALKANOIC ACID OF FROM 4 TO 6 CARBON ATOMS INCLUSIVE, TO RETAIN SAID UNCTUOUS MATERIAL AS A LUBRICANT.
2. The glass fibers of claim 1 wherein said acid is isobutyric acid.
3. The glass fibers of claim 1 wherein said acid is isopentanoic acid.
4. The glass fibers of claim 1 wherein said acid is isohexanoic acid.
5. GLASS FIBERS HAVING A COATING THEREON CONSISTING ESSENTIALLY OF THE FOLLOWING SOLIDS IN PERCENT BY WEIGHT: ESTERIFIED STARCH HAVING 5-90% ESTER GROUPS OF THE FORMULA R-COO-STARCH WHEREIN R IS AN ISOALKYL GROUP OF FROM 3 TO 5 CARBON ATOMS UNDERIVATIZED STARCH 0-75% SOLID UNCTUOUS MATERIAL 5-40% SECONDARY FILM FORMERS 0-5% NONIONIC OILS 0-5% CATIONIC LUBRICANTS 1-7% EMULSIFYING AGENTS 0.5-7% AN EFFECTIVE AMOUNT OF SAID ESTERFIED STARCH BEING PRESENT AS SWOLLEN AND UNBURST STARCH GRANULES TO RESTRICT MIGRATION OF THE UNCTUOUS MATERIAL THROUGH THE FIBERS.
