Difference between core spun yarn wrapped yarn

1. Manufacturing process

We take spandex core spun yarn spandex covered yarn as examples.

Core spun yarn is made of spandex wrapped with short fiber, with spandex as the core, wrapped with non elastic short fiber, which will be exposed during drawing. Therefore, the dyeing effect is good, it is suitable to make all kinds of products including dark colors. If the core yarn is wrapped well, the core yarn cannot be seen. ?

Spandex Covered Yarn is a kind of elastic yarn, which is made by wrapping spandex with the filament of chemical fiber, taking spandex as the core covering the stretch spandex with the non elastic short fiber filament in a spiral way. In the state of tension, the core is exposed, so it is suitable to make dark products. The core yarn the outer bread yarn can be seen.

2. Performance

The core of the core spun yarn is surrounded by the outer fiber, the combination of the two is relatively close. The core spun yarn the outer fiber have the same twist. However, there is no twist in the core of the covered yarn, the cohesion between the core the outer layer is significantly lower than that of the covered yarn. Therefore, the covering yarn is more elastic.

The hand feel of the covered yarn is harder than that of the core spun yarn. The strength of the covered yarn is the strength of the outer covering filament yarn, so it is higher than that of the core spun yarn of the same specification.

3. Production equipment

Core spun yarn is a staple made on a spinning frame. Generally, the spinning frame is used to add the textile materials that need to be wrapped in when drafting the roving. For example, cotton covered spandex; polyester, viscose covered spandex; cotton covered polyester filament; polyester covered polyester filament, etc.

Covering yarn is a kind of long fiber which is made on the splicing double twisting machine. One is the core yarn the other is wrapped outside. Such as spandex core yarn outsourcing polyester, nylon so on.

4. Application

The high-grade textiles, such as bedspread, bedspread, pillowcase, sofa cover, curtain, tablecloth so on, are made of core spun yarn fabric after dyeing printing.

Covering yarn is mainly used for knitted fabrics with high elasticity, it is an ideal yarn for high-grade thin wool, linen fabrics, jacquard double weft knitted fabrics warp knitted fabrics. Suitable for weaving sports tights, such as swimsuits, ski suits, lingerie, etc. According to the application, the core yarn the outer yarn should be selected properly, their strength is higher than any single yarn.
