6 points: the yarn must meet the requirements. Have the spinning enterprises selected the right yarn?

Knitting requires higher yarn evenness (i.e. yarn thickness uniformity), good softness, certain strength, extensibility and twist (yarn twist is relatively low). In the process of forming knitted fabrics on the knitting machine, the yarn will be subjected to complex mechanical effects, such as stretching, bending, twisting and friction. In order to ensure normal production and product quality, knitting yarn shall meet the following requirements:

one

The yarn shall have certain strength and extensibility

Since the yarn is subjected to certain tension and repeated load during preparation and weaving, the knitting yarn must have certain strength.

two

The yarn shall have good softness

The soft yarn is easy to bend and twist, and makes the loop structure in the knitted fabric uniform and the appearance clear and beautiful. At the same time, it can also reduce the yarn breakage and damage to the looping machine parts during the weaving process.

three

The yarn should have a certain twist

The yarn with too much twist will affect the elasticity of knitted fabric and make the loop skew. However, the twist of knitting yarn should not be too low, otherwise it will affect its strength, increase the broken ends during weaving, and the yarn is bulky, making the fabric easy to pilling.

four

The yarn shall have uniform linear density and less yarn defects

Yarn linear density uniformity, that is, yarn evenness, is an important quality index of knitting yarn. The yarn with uniform evenness is beneficial to the knitting process and the fabric quality, making the loop structure uniform and the cloth surface clear.

five

The yarn shall have good moisture absorption

The hygroscopic capacity of various fibers is very different, and the hygroscopic capacity varies with the temperature and humidity of the air. Under the same relative humidity, the yarn with good moisture absorption not only has good electrical conductivity, but also is conducive to the stability of yarn twist back and the improvement of elongation.

six

The yarn should have good finish and low friction coefficient

The knitting yarn shall be as smooth as possible without impurities and oil stains. The unsmooth yarn has severe abrasion on the machine parts and is easy to damage the machine parts. Moreover, there are many flying flowers in the workshop, which not only affects the health of workers, but also affects the productivity of knitting machines and the quality of fabrics.

Shandong Liyuan Fiber Co., Ltd. was established in 2002 and is located in Gaomi City, Shandong Province. It has a superior geographical position. It is 30 kilometers away from Qingdao Jiaodong airport in the East and 80 kilometers away from Qingdao port. Jiqing high speed railway station and Jiqing expressway are in close proximity. The transportation is very convenient and extends in all directions.

The company has 17 German truzler spinning machines, 3 French superba-tvp3 thermal setting machines, and 1 German PHS thermal setting machine. Meanwhile, it is equipped with various testing equipment such as the American Datacolor 800 color analyzer.

It can produce various specifications of polypropylene, polyester and nylon carpet yarn. The products are widely used in commercial block carpet, household carpet, full carpet and automobile carpet.
