Product Overview
The 1.6D*38MM room temperature dyeable cationic polyester staple fiber addresses key challenges in traditional polyester dyeing. Conventional polyester requires 130℃ high-temperature, high-pressure dyeing equipment, resulting in high energy consumption, extended processing times, and elevated costs for small-batch, multi-color production. This often leads to uneven dyeing and cylinder variation issues.
This cationic modified fiber achieves breakthrough dyeing performance through advanced molecular design. Cationic dye receptive groups are integrated into the polyester polymer chain, enabling cationic dyes to penetrate and bond evenly with the fiber at room temperature and atmospheric pressure. Compared to conventional polyester dyeing, this technology reduces energy consumption by over 40%, shortens dyeing cycles by approximately 30%, and significantly lowers production costs and carbon emissions.
The 1.6D fine denier design provides a soft, delicate fabric hand feel while improving dye uniformity due to the larger fiber specific surface area, preventing color streaks and spots. The 38mm standard cotton-type cut length is fully compatible with mainstream spinning systems including ring spinning, air-jet spinning, and open-end spinning, enabling direct production implementation without equipment modifications.
This fiber supports diversified product development: 100% pure spinning for bright solid color yarns; blending with ordinary polyester for one-bath two-tone fabrics; blending with cotton or viscose for high-quality blended fabrics that combine comfort with superior color performance. Every batch undergoes strict quality control for fineness, length, and dyeing consistency to ensure stable performance for downstream customers.
This material represents an ideal raw material for yarn mills, fabric factories, and apparel textile enterprises seeking to enhance production efficiency, reduce costs, and develop differentiated competitive products.
Application Scenarios
Color Spun Yarn Manufacturing: Pure spun or blended color spun yarns, heather yarns, and melange yarns for knitting and weaving applications. Room temperature dyeing enables flexible small-batch color production with minimal inventory pressure.
Blended & Two-Tone Fabric: Blended with regular polyester, cotton, or viscose to produce two-tone, shadow stripe, or heather effect fabrics. Ideal for casual wear, suit fabrics, wool-like textiles, and fashion apparel.
Knitted Apparel & Home Textile: Underwear, T-shirts, home wear, bedding, and decorative textiles. Delivers soft hand feel, bright colors, and excellent wash fastness for daily use products.
Fast Fashion & Quick Response Orders: Perfect for fast fashion brands and small-batch customized orders. Short dyeing cycles and low setup costs enable rapid color switching and fast order fulfillment.

Core Features & Benefits
- Room Temperature Dyeing, Energy & Cost Saving: Dyes successfully with cationic dyes at normal temperature and pressure, eliminating the need for 130℃ high-pressure dyeing machines. Reduces dyeing energy consumption by over 40%, shortens processing time, lowers production costs, and is ideal for small-batch, multi-color fast turnaround orders.
- 1.6D Fine Denier, Soft & Even Coloring: 1.6D fine denier structure provides larger specific surface area, ensuring uniform dye uptake and full vivid color without streaks or spots. The fine fiber delivers soft, smooth hand feel to finished yarns and fabrics.
- Excellent Color Fastness, Durable & Fadeless: Cationic dyes bond firmly with the modified fiber molecules. Outstanding wash, rub, and light color fastness prevents fading and color migration, maintaining long-lasting appearance for apparel and home textile products.
- 38mm Cotton-Type Length, Wide Spinning Compatibility: Standard 38mm cotton-type cut length matches ring spinning, air-jet spinning, and open-end spinning equipment. Can be processed on existing cotton spinning lines directly without equipment modification.
- Flexible Blending & Differentiated Fabric Development: Can be 100% pure spun into solid color yarns, or blended with regular polyester, cotton, or viscose fiber. When dyed in the same bath, it creates unique two-tone, heather, or melange fabric effects, helping manufacturers develop differentiated product lines.
- Virgin Quality & Stable Batch Consistency: Made from 100% virgin cationic modified PET chips with uniform fineness and length, low impurity and nep content. Strict color consistency control between batches minimizes fabric dyeing cylinder difference and reduces defective rates.

Frequently Asked Questions
Q1: What is the main difference between cationic polyester and regular polyester in dyeing?
A: Regular polyester requires 130℃ high-pressure dyeing with disperse dyes. This cationic fiber can be dyed evenly with cationic dyes at room temperature and atmospheric pressure, saving energy, shortening process time and reducing cost, especially for small-batch orders.
Q2: Can this fiber be blended with cotton, viscose or regular polyester?
A: Yes. The 38mm cotton-type length has good blending compatibility. When blended with regular polyester and dyed in one bath, it creates unique two-tone or heather fabric effects.
Q3: How is the color fastness? Will it fade easily?
A: Cationic dyes form stable chemical bonds with the modified fiber molecules. It has excellent wash, rub and light color fastness, and will not fade easily in daily use and washing.
Q4: Does it fit existing cotton spinning equipment?
A: Yes. The 38mm standard cut length matches ring spinning, air-jet spinning and other mainstream cotton spinning machines. It can be used directly without equipment modification.
Q5: Can we get samples for dyeing trial?
A: Yes, samples are available for dyeing test and spinning trial. Please contact us to request sample details.
Q6: What is the lead time for bulk orders?
A: Depends on order quantity. Standard specifications generally ship within 7-15 working days after deposit confirmation.
