Product Introduction
Moisture-wicking polyester hot melt yarn is a thermal-bonding component developed for inclusion in knitted polyester textile systems. It is made from 100% polyester and supplied in white. The product range identifies 50D, 70D, 100D and 150D options and a 110°C melting point. Moisture transport remains a property of the engineered textile, so approval should be based on the processed fabric rather than the yarn name.
Engineering focus
Position the bonding component without disrupting the capillary routes designed into the textile.
Separate the Bonding Function from the Fabric Claim
This polyester yarn performs a heat-activated fixation task. Wicking depends on how the surrounding yarns, loops and channels handle liquid. Treating these as two separate design questions makes development results easier to interpret.
1
During Knitting
Feed the yarn into the specified course, wale, edge or reinforcement area of the construction.
2
During Activation
Apply a controlled thermal cycle and observe the amount and direction of polymer flow.
3
During Qualification
Measure the processed article against separate bonding and moisture-transport acceptance criteria.
Polyester hot melt yarn supplied on cones for knitting and textile processing.
Product Specifications
| Polymer | Polyester (100%) |
|---|---|
| Thermal reference | 110°C melting point |
| Yarn-count range | 50D / 70D / 100D / 150D, etc. |
| Standard shade | White |
| Processing formats | Flat knitting, hosiery knitting, circular knitting and warp knitting |
Temperature selection: Use 110°C as a material reference only. Establish equipment settings from trials that account for heat delivery, residence time, applied pressure and the thermal limits of every adjoining yarn or layer.
Prepare a Usable Development Brief
A clear brief lets the supplier and mill discuss yarn count, feeding and thermal treatment around the same construction. Include the following four groups of information before sample work begins.
1
Construction Drawing
Mark the technical face, skin-facing surface, liquid-transfer direction and exact course or layer receiving the bonding yarn.
2
Fixation Objective
Describe the movement that must be controlled and the areas that must remain open, flexible or visually unchanged.
3
Mill Setup
Share equipment type, needle gauge, feeder position, running tension and any known limitations of the downstream heating unit.
4
Release Standard
Define how bond integrity, handle, surface quality, dimensional change and liquid transport will be judged.
- Requested yarn count or comparison cone
- Composition of every textile layer
- Knitting platform and needle gauge
- Course, wale or zone receiving the yarn
- Available thermal equipment and limits
- Required laundering or conditioning cycle
- Order volume and delivery destination
- Identification and packing instructions
Machine Information That Changes the Trial
| Equipment | Development question | Sample observation |
|---|---|---|
| Flat knitting | Which shaped area, edge or transition needs fixation? | Whether the chosen count feeds cleanly and preserves the panel outline after heating |
| Hosiery knitting | Where can the bonding yarn sit without creating a hard contact area? | Whether the activated zone retains the required extension and comfortable surface |
| Circular knitting | How often will the yarn be fed around the tubular structure? | Whether activation is even across the width and keeps the intended open structure |
| Warp knitting | Which guide and lapping position will carry the thermal component? | Whether the bonded architecture remains stable without visible polymer displacement |
Use a Paired-Sample Qualification Method
Keep an unactivated or non-bonded comparison whenever practical. A paired approach helps the development team see which changes come from the thermal yarn and which come from the base textile.
Phase A
Baseline Knit
Produce a representative panel and document yarn position, machine settings and any feed irregularity.
Phase B
Controlled Heating
Create several coded samples with defined thermal conditions instead of changing multiple variables together.
Phase C
Side-by-Side Review
Compare fixation, touch, visual change and open-area retention against the baseline construction.
Phase D
Release Testing
Condition the selected sample and run the buyer's required liquid-transport and service tests.
A polyester composition statement does not establish a wicking result. Retain the qualified construction, test protocol and numerical acceptance criteria with the approved reference sample.
Keep the Approved Result Reproducible
The production team needs more than a product name. Transfer the yarn identification, textile build, machine record, thermal recipe and inspection standard together with the retained sample.
Order Match
Compare polymer, yarn count, shade and lot marking with the confirmed purchase details.
Package Inspection
Check cones and wrapping on receipt, then observe the first unwinding run before release.
Knitting Standard
Use the approved feeder, gauge, running tension and yarn position for the first production panel.
Thermal Standard
Repeat the qualified equipment setup and record any adjustment made during scale-up.
Surface Standard
Compare sheen, thickness, polymer visibility and fabric outline with the retained reference.
Release Standard
Apply the agreed inspection and textile test plan before accepting the production lot.
Yarn winding, production handling, packaging and finished cones.
Plan the First Development Run
Share the textile drawing, machine platform, yarn-count target, fixation zone, thermal equipment, qualification method and order volume.

Frequently Asked Questions
What role does this yarn play in a moisture-management fabric?
It supplies a heat-activated fixation element within the knitted construction. Liquid transport is created by the complete textile design, including the surrounding fibers, loop architecture, channels and finishing.
What yarn counts can be discussed for sampling?
The identified range covers 50D, 70D, 100D and 150D, with other specifications indicated. State the target count, equipment gauge and comparison material in the enquiry.
How should the 110°C melting point be used?
Treat it as a polymer reference for planning trials. The machine setpoint must be developed around heat-transfer efficiency, residence time, pressure and the thermal tolerance of the entire construction.
Can the same yarn setup be transferred between knitting machines?
Do not assume a direct transfer. Flat, hosiery, circular and warp knitting equipment use different yarn paths and construction controls. Recheck gauge, feeding, tension and placement for each platform.
Why is a non-bonded comparison sample useful?
It helps isolate changes introduced by thermal activation. Compare liquid transport, handle, appearance and dimensions with the bonded version before finalizing the process.
What should a mill send before requesting a trial cone?
Send the textile build, knitting platform, needle gauge, requested count, yarn position, fixation objective, thermal equipment, release tests, volume and delivery destination.
