The difference in the expression of wool yarn count and wool raw material count

In the textile industry, the count of wool yarn and wool raw materials is an important indicator for measuring their thickness and quality. Understanding these indicators not only helps us choose suitable yarns and raw materials but also enables us to better evaluate the performance and application of textiles. The following will extend the discussion on the representation methods and corresponding relationships of wool yarn counts from two dimensions: wool yarns and wool raw materials.

1. The representation method of wool yarn count

The number of wool yarn is expressed inmetric count(Nm) is a fixed weight measurement method. The definition of metric yard is: the length of yarn is how many meters under the weight of 1 kilogram of yarn. The calculation formula is:

Nm = yarn length (m) / yarn weight (kg)

The relationship between the number of threads and the thickness: the larger the number of threads, the thinner the yarn; the smaller the number of threads, the thicker the yarn.

application scenarios:

Pure wool yarn: made of pure wool, it has natural warmth and is often used in high-enD Clothing and home products.

scribbled: By blending wool with polyester, viscose, nylon and other fibers, it combines the softness of wool with the durability or elasticity of other fibers, suitable for large order fabric orders.

Wool polyester blended yarn: widely used in outerwear, uniforms and other fabrics with high wear resistance.

Wool viscose blended yarn: suitable for making light and moisture-absorbing fabrics.

Wool nylon blended yarn: suitable for clothing with high elasticity requirements, such as sportswear or casual wear.

2. The representation method of wool raw material count

The number of wool raw materials is also referred to as "branch" (or"Number of wool strands") indicates, but unlike the count of yarns, its unit of measurement is based on the diameter of wool fibers, i.e., fineness. Wool count indicates the theoretical number of yarn counts that can be produced from a given weight of wool. The higher the fineness, the higher the wool count, indicating better quality raw material.

Common wire count:

Coarse wool: commonly used 48,50,54,58, mainly used to make heavy, warm wool fabrics, such as coats and blankets.

Fine wool: mostly 66 or more, suitable forFine woven fabricSuch as suit fabric, high-end wool sweater, etc.

The relationship between wool strand number and wool fineness: The fineness of wool raw material is measured in microns (μm), which is usually as follows:

48 wool strips: corresponding to a fineness of about 28-30μm, belonging to coarse fiber wool.

50 wool strips: corresponding fineness of about 26-28μm.

54 wool strips: corresponding to a fineness of about 24-26μm, belongs to medium quality wool.

66 wool strips: corresponding to a fineness of about 20-22μm, high quality wool.

More than 80 wool strips: corresponding fineness is less than 19μm, mostly ultra fineMerino wool, used for top quality wool products.

3. Comprehensive application of wool raw materials and yarn

In actual production, wool yarn and raw material count complement each other. Different count selection directly affects the performance and application range of finished products. For example:

Coarse fabrics:

Select 48-58 wool strips, yarn count less than 10Nm. The finished products are mostly heavy and warm winter clothing, such as wool coats.

Features: rough and strong feel, suitable for heavy design style.

Fine knit fabric:

Select more than 66 wool strips, the yarn count can reach 30-60Nm. The finished products are mostly light and thin, high density fine spun suit fabric.

Features: high gloss, high strength, suitable for making clothes with fine cutting.

Twist selection of blended yarn:

Coarse spun yarn: the proportion of polyester and wool is large, the count is generally low, suitable for fabrics with high wear resistance requirements.

Fine blended yarn: more attention to softness and elasticity, higher count, used for high grade fabrics.

4. Factors affecting market trend and number selection

With the progress of textile technology and the change of consumer demand, the selection of wool yarn and raw material count is also affected by many factors:

Quality demand: High-count wool fabric has gradually become the mainstream of the market because of its delicate touch and thin texture.

Environmental trend: The increase of wool and renewable fiber (such as silk, viscose) blending ratio promotes the development of medium and high count blended yarn.

Functional development: Functional fibers such as polyester and nylon are added to expand the application of wool yarn in sports and outdoor clothing.

5. Summary and suggestions

Whether you choose wool yarn or raw wool, it is important to understand the meaning and corresponding relationship of its count. The following suggestions are for your reference:

Clear requirements: According to the use and performance requirements of the product, choose the appropriate yarn count and raw material count.

Attention to cost: although high count yarn and wool are of good quality, the cost is high. Budget and target market positioning should be comprehensively considered.

Experimental innovation: Try the combination of wool and new fiber to endow the product with more functions and market competitiveness.

Through the reasonable use of branch knowledge, not only can the production process be optimized, but also the product quality can be improved, so as to better meet the diversified market demand.
