Embodiment 1

[0068] The preparation of embodiment 1-lactam

[0069] In a covered vessel, melt four liters of caprolactam overnight in a convection oven. The lactam was poured into a 5 liter 3-neck distillation flask with a magnetic stir bar and electric heating mantle (top and bottom mantle). The distillation column has a vacuum jacket and consists of a 29 / 42 column and 10 tray section, 5 tray section, split distillation head and condenser. The condenser was maintained at 50°C using a heated water circulator. The system reduces the pressure from 7 mmHg to 4 mmHg. Heat was applied to bring the column to reflux conditions and held for 30 minutes. After allowing the column to stabilize for 30 minutes, the distillation head sampler was started, 4 seconds off, and 10 seconds to reflux. Slightly less than 1 liter of lactam was distilled off. The heat was turned off, and the heating mantle was removed, the lactam in the 5-liter flask was allowed to drop to 90°C, and then the vacuum on the sy...

Embodiment 2

[0070] Example 2 - Preparation of contemplated pre-fiber gel compositions

[0071] the gel

[0072] The resulting gel was gel-spun on a twin-screw extruder. The gels are surprisingly well spun into fiber products, and fiber bales can be prepared under most conventional spinning conditions. Furthermore, it can be seen that the extruder temperature can be lowered below conventional neat polymer conditions, provided the gel composition allows lower extruder pressures. Tables 1-5 shown below give a summary of several spinning conditions used in these examples.

Embodiment 3

[0073] Example 3 - Preparation of contemplated pre-fiber compositions

[0074] background

[0075] A conventional binder alloy sample (1-end of 22 denier / 12 filaments) was inserted into 1202mp 2-ply yarn during cabling and Superba(R) heat set. After Superba(R) heat setting, the Plybond test of the yarns did not show any signs of bonding. Subsequently, the yarn is autoclave heat set before being processed into banded carpet. No significant aesthetic effect was observed in the carpet using any of the conventional binder alloy samples. However, at the lowest nylon / binder ratio, there was a slight impact on carpet hand (firmness), but no texture or surface changes were observed in the carpet.

[0076] This study tested compositionally altered low-melt alloy fibers (higher process "binder" and higher lactam concentration). The goal of the research was to find an alloy composition that would melt and bond the fibers together within the bundle during Superba(R) heat setting. The...

Abstract

Disclosed herein is a pre-fiber composition comprising: a) a first fiber component having a first melting point; b) a second fiber component having a second melting point; and c) a gelling agent that combines the first fiber component or the second fiber component Solvation of at least one of the two fiber components, wherein the gelling agent substantially reduces copolymerization of any one component of the composition. Also disclosed herein is a fiber comprising: a) at least two amide-based polymers, each having a melting point, wherein one amide-based polymer has a different melting point than the second amide-based polymer; and b) a gelling agent compatible with at least one of said amide-based polymers, wherein said fibers have two distinguishable melting points substantially similar to those of said amide-based polymers Each melting point. Disclosed herein is a method of producing a pre-fiber composition comprising: a) providing a first fiber component having a first melting point; b) providing a second fiber component having a second melting point, wherein the first melting point and the second melting point are different c) providing at least one gelling agent; and d) mixing the first component, the second component, and the at least one gelling agent such that the composition has sufficient viscosity and sufficient melt strength so that it can be Spinning forms fibers, and the first and second melting points of the fibers are substantially similar to their original values ​​prior to blending.

Description

technical field [0001] The technical field that is the subject of the present invention is multiphase pre-fibrous and fibrous materials and compositions, fibrous, yarn and carpet products, methods of their manufacture and uses. Background technique [0002] There is a constant interest in improving the aesthetics and performance of fibers for consumer use, especially for incorporation into yarns, carpet products and fabrics / textiles. These improvements may relate to appearance retention, texture and surface shape, softness and floor wear performance. Fibers and fiber products are also evaluated to determine if more efficient and cost-effective manufacturing processes and equipment exist. [0003] Fibers that can be used to produce carpet products such as room rugs, area rugs, and rugs are modified to provide a certain yarn texture when they are introduced into the carpet product and provide the desired "look" for the space in which the carpet product is used. Sex and in so...
