300D Folded Texturized Fancy Yarn with Irregular Slub for Making European Curtain

1.Description:

The development of fancy yarns represents a model example of how a market can be dynamically stimulated using creative ideas that can attract consumers and draw attention to the products with minimum added cost. Indeed, most fancy yarns merely represent random effects introduced to the traditional yarns using simple accessories mounted on conventional spinning machinery, such as ring spinning or rotor spinning. The manufacturing cost that may be added as a result of using these accessories is largely counterbalanced by many other factors that can indeed result in a net cost reduction. For example, fancy yarns that are a result of induced irregularities and discontinuities require quality constraints and testing procedures that are much less than those implemented for traditional yarns. In addition, the possibility of using a wide range of fibers including low quality fibers and a variety of fiber wastes also adds to the overall reduction in manufacturing cost.

3,Advantages:

In general, fancy yarns may be divided into two major categories:^4,7,15 mono-fancy yarns and compound fancy yarns. The former are made from a single staple-fiber strand or multifilament yarn in which irregularities are introduced during the conversion from fibers to yarns; the latter consist of two or more fiber strands used to provide the desired combined effects. Figure 9.6a and 9.6b represents two examples of the first type of fancy yarn, namely slub yarns and thick and thin yarns. A slub yarn is basically a spun yarn (ring or rotor-spun yarn) in which thickness variations are deliberately induced by variation in the yarn twist combined with control of the fiber feed so that thick areas will exhibit lower twist than thin areas. Key structural parameters associated with slub yarns include slub size with respect to yarn diameter, slub length and slub spacing or frequency. Typically, slubs are randomly and irregularly spaced along the yarn axis. A thick-and-thin yarn is typically a multifilament yarn in which diameter variations are deliberately induced by variation in the filament flow rate through the spinneret during extrusion. This type of yarn provides a unique surface texture to the fabric made from the yarns similar to that of linen fabrics.

4,Why is fancy yarn important?

Fancy yarns have wide-ranging application in apparel at all levels of the market. Where once the extreme complexity and difficulty of making and using fancy yarns inhibited their production in sufficient quantity or at a low enough price for the mass market, improved process control has now greatly extended their market penetration. In particular, fancy yarns have become an increasingly prominent part of the revived hand knitting market.
