[Technology] Knitting Yarn Requirements?

The conventional number of knitting yarns is between 7S and 40S, and less than 45S is used.

The most commonly used knitting number: 20S/21S 26S 30S/32S 40S.

Less than 16S and 40S or more are used.

Second, the use of each yarn branch

7S~16S is used for the bottom yarn of terry velvet for thicker jersey.

20S/21S is used for the bottom yarns of pile loops, bead net mesh cloths, and jersey cloths.

26S~32S is used for veil, jersey and other fabrics.

40S is used for terry veil, jersey and other fabrics.

Third, the index requirements of knitting yarn

Dry CV%.

Details (-50%), thick section (+50%), cotton grain (+200%).

Hairiness: If the hairiness is longer than usual, weaving can easily take off flowers. The fabric is easy to pick up and pilling. The high cloth is required to do hair removal.

Twist: Knit twist is lower than twist of woven yarn. Twistiness is high in weaving. The fabric feels harder. If it is raised from velvet, it needs to be weak.

Strong: Knitting yarn does not require strong strength unless there are special requirements.

Foreign fiber: The standard for knitted fabrics is: 20 pieces/cloth (20~25kg).

The test indicators can refer to the USTER bulletin. The yarn quality test indicators can reach USTER 5%~25%.

Fourth, seasonal knitting

The seasonality of knitting is stronger and it is divided into two seasons in a year:

From March to June each year, this season's production of autumn/winter (F/W, F/H) large cargoes and the development of the next spring/summer (S/S), large-lot yarns are mostly coarse-bricked and the color is medium-sized. Dark colors are more.

From September to December of each year, the production of spring/summer (S/S) in this season and the development of autumn/winter (F/W, F/H) in the next season, the yarns for large goods are finely supported, 32S, 40S are more. , and with light colors as more.

Fifth, the trend of the recent knitting yarn

In recent years, due to the high price of cotton, the original cotton yarns began to use CVC, T/C, or cotton/polyester fabrics.

The decline in the profit of pure cotton yarn has led to the transformation of knitting factories and the increased use of various functional, conceptual, and differentiated fiber yarns.

New spinning methods: MVS, low torque yarns, etc.
