| Friction control is the most important characteristic of a BCF spin finish. Understanding the impact of fiber surface interactions in the BCF process is crucial to developing properly balanced finishes. |
|
| Two of the primary characteristics influencing consumer carpet selection are appearance (color, style and construction) and tactile feel. The appearance of the carpet is limited only by the creativity of the carpet designer while the tactile feel or hand can be modified by a variety of technical approaches during carpet yarn manufacturing. |
|
| There has been greater interest recently in engineering of the tactile feel of yarn and ultimately, the carpet, through surface treatments. Common approaches used to manipulate tactile feel of the final carpet are: |

| The topical treatment approach to improving softness offers advantages over mechanically modifying fiber properties, such as maintaining productivity levels with no capital expense incurred. In some cases, topical treatment can be used to obtain softness beyond what can be accomplished by changes in fiber properties. Softeners applied in conjunction with the fiber lubricant system at spinning yield better uniformity, and therefore can be effective at lower lubricant levels. Modifying the surface of a fiber to produce a soft-hand carpet can be done topically or by incorporation of polymer additives. |
