Product Description

ECDP Chips&Low Melting Chips:

The ECDP fiber has uniform longitudinal thickness and smooth surface. Good tensile property;, Good elasticity of crimp; The friction factor is large; High moisture regain; Less mass than resistance. Finish the dyeing process within 100ºC. 
It is highly suitable for use in combination with nylon/acrylic/cotton fibers, effectively solving the problem of difficult dyeing and enhancing the comfort of the fabric.Adored by Chinese seamless underwear factories
Main Spec: 30D~150D  S&Z&S+Z(2ply) Twist
 
Semi-Dull/Full-Dull Cationic Series:
Change the common rule of Bright in the cationic yarn market, Semi-dull and Full-dull finishes make the yarn color whiter, and the color of the fabric after dyeing is more fashionable and high-end, providing more possibilities for dyeing. 
Main Spec: FDY/DTY 30D~300D

Full-Dull/Semi-Dull/Optical White Series:

It is widely used in garments, shoes and so on, especially for making shirts, shoes,white socks, white medical clothing, sports clothing, trademarks, sewing thread, white gloves, etc.
Main Spec: FDY/DTY  50D~150D
 
Mother yarn&Mono yarn
The mother yarn produced by chips has better physical properties and workability than the yarn directly spinning by melt, and can be customized to produce SD/BR/CDP/FR/HSR mother filament.
Both splitting and direct spinning/polyester and nylon/paper and iron tube, packing and using can be a variety of options, easier to complete cost control and switching.
Mother Yarn :100D~500D Nylon&Polyester
Mono Yarn :10D/1F~50D/1F Nylon & Polyester

ECDP Chips&Low Melting Chips:

Excellent Dyeing Performance: It can be dyed using cationic dyes at 95°C under normal atmospheric pressure, achieving deep color and vibrant shades.
Good Physical Properties: High strength and elongation
Improved Moisture Absorption: Slightly better moisture absorption compared to regular polyester, improving wearing comfort.
Good Spinnability: Easily processed and shaped during fiber manufacturing.
Energy Efficiency: Due to the low melting point, energy consumption can be reduced during processing.
The melting point ranged for producing low-melting-point chips is from 110°C to 230°C.
