Abstract:
The invention concerns a temporary sizing agent for natural and/or artificial individualized textile fibers, characterized in that it comprises a water-soluble homopolymer or copolymer of at least one acrylamide monomer having a molecular weight not less than one million, advantageously more than three millions.
Abstract:
The invention pertains to a method for improving bundle cohesiveness of a bundle of aramid yarns and decreasing its friction coefficient, comprising adding to the bundle of yarns 0.1 - 3.0 wt.%, based on the yarn weight, of a water-soluble or water-dispersible film forming binding agent, followed by treating the bundle of yarns with an oil having an intrinsic viscosity less than 100 mm 2 /s.
Abstract:
A fiber finish, particularly for cellulose acetate tow, is an emulsion of 62.0 to 65.0 weight percent mineral oil, 27.0 to 28.0. weight percent emulsifiers, and the balance being water. The emulsifiers are a mixture of 50.0 to 520. weight percent sorbitan monolaurte and 48.0 to 50.0 weight percent POE (20) sorbitan monolaurte. The finish has an add-on weight of 3 to 8 weight percent of the total weight of the tow.
Abstract:
This invention provides a process for the topical use of an ethoxylated alkyl phosphate ester additive on a cellulose acetate tow band as a plugmaker processing aid. The invention also provides a composition comprising an ethoxylated alkyl phosphate ester additive and cellulose acetate fibers.
Abstract:
The present invention relates to the application of lubricant to fluoropolymer yarn which enables the yarn to be drawn at a high draw ratio and is removable by scouring, the lubricant being thermally stable at a temperature of at least 120 °C, and being removable from the yarn by scouring and comprising oil and surfactant and/or wetting agent to enable the lubricant to spread over the surface of the yarn upon application to the yarn, the lubricant comprising oil such as a C6-C20 aliphatic acid ester of a polyol and a surfactant and/or wetting agent.
Abstract:
Non-woven materials from polyolefin-based fibres which have bulk and resilience comparable to polyester fibres are described herein, thus expanding the utility of polyolefin fibres and nonwovens to a plethora of industrial applications which previously excluded products based on polyolefin fibres due to their hitherto inadequate bulk or resilience. Control of polyolefin fibre characteristics such as the fibre/fibre friction, fibre crystallinity, draw ratio, or selection of the spin finish so as to comprise essentially of an aqueous emulsion of polysiloxanes render them suitable for preparing bulky and resilient nonwovens.
Abstract:
One aspect of the present invention relates to a clay-containing synthetic textile material lubricant composition comprising a synthetic textile material lubricant, clay, and a dispersant in an amount sufficient to stably suspend the clay in the composition. Another aspect of the present invention is a method of lubricating synthetic fibers or filaments used in forming synthetic filaments from the fibers or yarn from a monofilament or multiple filaments or lubricating synthetic filaments or synthetic yarn during subsequent processing or handling, where the method comprises using the composition of the present invention as the lubricant.
Abstract:
There is provided a composition comprising a lubricant, preferably a water-soluble one, and components having a deviation of fabric wrinkle recovery angle versus water of at least +15, whereby the combination imparts in-wear wrinkle resistance to the fabric treated therewith.
