Custom Polyester Ammonia Knitted Elastic Fabric For Swimwear

In the weaving process of polyester ammonia knitted elastic fabric for swimwear, what key process parameters need to be controlled? For example, how are the warp let-off amount, draft density, etc. set? What impact do these parameters have on fabric performance?

1. Control of warp let-off amount
The warp let-off amount refers to the amount or speed at which the warp yarn is fed into the loom during the weaving process. In the weaving of polyester-spandex knitted stretch swimwear fabric, the control of the warp let-off amount is particularly critical because it directly affects the elasticity and stability of the fabric.
Setting of warp let-off amount:
For polyester-spandex knitted stretch fabric, the setting of the warp let-off amount needs to be more refined due to the addition of spandex yarn. Spandex yarn has good elasticity, but excessive stretching will cause the fabric to lose its original elasticity and stability. Therefore, when setting the warp let-off amount, the elastic properties of spandex yarn must be fully considered.
JUNRUI uses an advanced warp let-off system that can accurately control the warp let-off amount to ensure uniform feeding of the warp yarn during the weaving process. At the same time, the company also makes personalized adjustments to the warp let-off amount according to the specifications of the fabric and the specific needs of the customer.
The influence of warp feed on fabric performance:
If the warp feed is too large, the fabric will be overstretched, reducing the elasticity and stability of the fabric, affecting the comfort and service life of wearing.
If the warp feed is too small, the fabric will be tight, increasing the difficulty of weaving, and the fabric will be prone to creases and cracks.
A reasonable warp feed setting can ensure that the fabric has stable size and shape while maintaining good elasticity, meeting the high requirements of swimwear fabrics for elasticity and stability.
2. Control of pulling density
The pulling density refers to the degree of stretching of the fabric by the pulling device during the weaving process, which directly affects the tightness and elasticity of the fabric.
Setting of pulling density:
The setting of pulling density needs to be adjusted according to the specifications and uses of the fabric. For polyester-spandex knitted stretch swimwear fabrics, the pulling density should be moderate to ensure that the fabric has both sufficient tightness and good elasticity.
JUNRUI uses advanced pulling devices and control systems to accurately control the pulling density. The company also makes personalized adjustments to the pulling density according to the characteristics of the fabric and the specific needs of customers to meet the needs of swimwear fabrics in different markets.
Effect of pulling density on fabric performance:
If the pulling density is too high, the fabric will be too tight, reducing the breathability and wearing comfort of the fabric. Excessive pulling will also cause stress concentration in the fabric, increasing the risk of fabric damage.
If the pulling density is too low, the fabric will be too loose, reducing the elasticity and stability of the fabric. In addition, too low a pulling density will also affect the appearance and feel of the fabric.
A reasonable pulling density setting can ensure that the fabric has good breathability and wearing comfort while maintaining tightness and elasticity. This is crucial for swimsuit fabrics, because swimsuits need to fit the skin for a long time, and have high requirements for the comfort and stability of the fabric.
3. Control of other key process parameters
In addition to the warp feed and pulling density, in the weaving process of polyester-spandex knitted stretch swimsuit fabrics, it is also necessary to control several other key process parameters, such as knitting density, yarn tension, etc.
Knitting density: Knitting density refers to the number of coils per unit length. It directly affects the thickness, tightness and elasticity of the fabric. JUNRUI uses advanced knitting equipment and technology to accurately control the knitting density, ensuring that the fabric has good breathability and comfort while maintaining elasticity and stability.
Yarn tension: Yarn tension refers to the tensile force exerted on the yarn during the weaving process. It directly affects the flatness and uniformity of the fabric. JUNRUI uses a precise tension control system to ensure that the yarn maintains a stable tension during the weaving process, thereby producing a flat and uniform fabric.
