Why Do Yarns Have Knots?
WHY DO KNITTING YARNS HAVE KNOTS?
The knots are there for technical production reasons. Our aim is to have as few knots in one ball as possible.
WHAT HAPPENS WITH THE KNOTS IN MULTICOLOURED YARNS?
For technical production reasons the multicoloured yarns also include knots. If the knot has been made prior to dyeing or printing the repeat of the yarn is not affected. If the yarn has been knotted after dyeing or printing, the repeat may show changes. In production, yarns cannot be joined so that the repeat would always continue as regular following the knot. We recommend that you check that the pattern continues correctly after a knot. If necessary, you can unravel the ball up to a point where the repeat continues as desired, and retie the knot.
WHY DOES THE YARN LABEL INCLUDE A BATCH NUMBER?
Because of dyeing techniques, one colour can never be repeated completely identically from one batch to the next. The colour variation may seem very small when comparing balls, but in a complete knit the variation may be more obvious.
WHY DOES THE WEIGHT OF YARN BALLS VARY?
Regardless of the weight of the ball at the time of purchase, the metric length of the yarn is always as specified on the label. The weight of the ball does not affect the metric length of the material. The differences in weight are caused by the drying of the wool following production. Wool has a high capacity to absorb moisture without feeling damp. 7 Veljestä yarn may absorb moisture as much as 15% of its weight. Similarly, when drying out, a 150 gram ball may weigh a lot less. It is therefore not uncommon that the weight of a ball of yarn may be as low as 140 grams in dry conditions.
In yarns made from synthetic materials, the variation in weight is not as noticeable, as they cannot absorb or bind large quantities of moisture.
