What is the difference between crochet yarn and regular yarn?

Yarn is one of the most basic materials in the production of fabrics and handicrafts, and "crochet yarn" and "regular yarn" are two common types of yarn, which are often confused by handicraft enthusiasts and knitters. In fact, the two are different in terms of use, fiber structure, feel, and applicable tools.
Regular yarn generally refers to knitting yarn, which is mainly used for knitting. Knitting is a process of knitting with two or more needles at the same time. Regular yarn is diverse and suitable for knitting various knitted garments, scarves, hats, etc.
1. Difference in yarn structure and texture
Crochet yarn usually has the following characteristics:
Moderate and uniform thickness: The crochet hook needs a certain tension and elasticity of the wire, and the wire diameter is uniform to hook out a flat pattern;
Moderate softness: It is convenient for the crochet hook to thread, and the hooked work must be elastic and three-dimensional;
Various types of fibers: including pure cotton, wool, acrylic, etc., choose according to the needs of the work.
Ordinary wool yarn has a wider range, including wires of varying thicknesses. Some are thinner and suitable for knitting dense clothing, while some are thicker and used to knit thick sweaters and scarves. Knitting with knitting needles requires higher elasticity and feel of the yarn, while ordinary wool yarn emphasizes the overall softness and comfort of the fabric.
2. Different applicable tools
The name of crochet thread comes from its dedicated crochet knitting tool. The crochet needle is a single needle with a hook. The operation method is to hook out the coil to form various different patterns. Crochet thread is usually designed to match the size and feel of the crochet needle for easy operation.
Ordinary wool yarn is mainly matched with knitting needles. There are two or more knitting needles. The knitting needles are used to circulate and intersperse the wool yarn to form a knitted structure. Knitting needles have higher requirements for the elasticity and softness of the wool yarn, and ordinary wool yarn is usually more suitable for this.
3. Different finished product effects
Crochet thread is suitable for crocheting works with rich patterns and strong layering, such as lace, crochet shawls, wool dolls, etc. Crochet works are often thicker and have a strong three-dimensional sense.
Ordinary wool is suitable for knitting clothes, hats, socks and other apparel products. The fabric is soft, has good ductility, and the finished product feels comfortable.
The boundary between crochet and knitting is not absolute. Many wool can be used with both crochet and knitting needles, but in order to achieve the best results, it is more appropriate to choose professional yarn.
The difference between crochet yarn and ordinary wool is mainly reflected in the use, structure, feel and finished product effect. Crochet yarn is specially designed for crochet crafts, emphasizing uniform wire diameter and moderate softness, which is convenient for hooking out rich patterns; ordinary wool has a wider range of uses, is suitable for knitting and many other handicrafts, and focuses on the softness and comfort of the finished product.
