A dye lot marking from a yarn label. The dye lot is the large stamped number at top. Other information such as color code has been preprinted in smaller digits. A dye lot is a record taken during the dyeing of yarn to identify yarn that received its coloration in the same vat at the same time. Yarn manufacturers assign each lot a unique ...
Originally meant also as part marking code, this shorthand notation is widely used in electrical engineering to denote the values of resistors and capacitors in circuit diagrams and in the production of electronic circuits (for example in bills of material and in silk screens).
The technique is to wrap the yarn around all of the spool's pegs, twice. The lower loop of yarn is then lifted over the upper loop and off the peg, thereby creating stitches. The yarn is then wrapped around the entire loom, creating a new upper yarn on each peg. This process is repeated until the project is complete.
Textile fibers, threads, yarns and fabrics are measured in a multiplicity of units.. A fiber, a single filament of natural material, such as cotton, linen or wool, or artificial material such as nylon, polyester, metal or mineral fiber, or human-made cellulosic fibre like viscose, Modal, Lyocell or other rayon fiber is measured in terms of linear mass density, the weight of a given length of ...
They manufacture 7 types of spun lopi yarn and also unspun lopi, all in a variety of natural fleece shades and in a range of dyed colours. The yarn is available in stores in Iceland and all over the world. [citation needed] Characteristic Icelandic lopapeysa sweaters are generally made from the thicker lopi yarns. [3]
The grade of numbered duck refers to the number of ounces subtracted from 19 for a 36-by-22-inch piece of fabric. For example, a piece of No. 8 numbered duck with dimensions of 36 by 22 inches weighs 11 ounces (310 g) (19 − 8 = 11). [5] Number duck classifications per linear yard, 22 inches wide
In textile spinning, yarn realisation (YR), or yarn recovery, is an operational parameter of yarn manufacturing. It is the percentage conversion of raw material to finished yarn . The rest of the waste fibers with less value are compared to the weight of the produced yarn from a given weight of raw material.
A way of determining the weight of an unknown yarn is to use the wrapping method. This method is also used to calculate the amount of yarn needed for a project. By this method it is possible to check an unknown weight of yarn with a regular pencil and ruler [3] without unwinding the yarn. Simply slip the pencil under approximately an inch of ...
