Yarn twist Download Now Download Download to read offline. As it costs money and reduces production; yarns are seldom-twisted full. But voil and crepe threads are purposely hard twisted. It is then is termed soft, medium, medium hard or hard. For crepon or sheersucker effect and for cord effect, threads are made hard twisted.
It can be S, left handed regular or open hand or Z right handed reverse or cross hand. A hard twisted thread becomes wiry, resists liquid penetration and flattens with difficulty. It also acquires a certain amount of elasticity and a tendency to snarl and resist change. An mf yarn is as strong without twisted condition as in twisted condition.
It disturbs parallel configuration of monofilaments and their load sharing capacity. A certain amount of twist helps in weaving of mf yarns. Terms, twist per meter and twist per inch are used in continuous filaments and staple spun yarns respectively.
Z twist if they're single ply and having a final S twist if they're plied. Knitting or crocheting with a yarn changes the amount of twist. How it changes depends on the final twist direction of the yarn and the direction in which you wrap the yarn around the needle. Does that matter? Adding more twist to your yarn causes it to tighten up, making it slightly stronger and less susceptible to pilling, and also making the stitches easier to work and less likely to split.
Reducing the twist in a yarn makes the fibers and plies separate and it is more difficult to work without splitting the yarn.
Whether you hold the yarn in your right hand English or throwing style or your left hand Continental or picking style you are still using the 'Western' method. The 'Combined' method uses a mix of the two. So the good news for most 'Western' knitters is that they introduce more twist into the commonly available S-plied yarns.
In this picture, showing a swatch I made using an S-plied yarn, the stitches on the needle have plenty of twist where they were made with the Western knitting method, but the plies have separated where the Eastern method was used.
For crochet, the opposite is true - in the pictures below, the plies of the S-plied yarn have separated, while the stitches of the single with its Z twist are tightly spun. The smoothness of the fabric into which the yarn is to be converted -yarn required for smooth-surfaced fabrics are given many twist per inch.
They are hard twisted yarns and they give strength, smoothness, elasticity and some crease-resistance of fabrics. Any other special attribute of the fabric into which the yarn is to be converted -yarns required for crepe fabrics with rough, pebbly or crinkled surfaces are given a maximum amount of twist. The crepe yarns also confer enhanced cease resistance to the fabric. Icon color: Change color to parent color on hover. Textile Physics Twist in yarn. Yarn Engineering.
