150D Polyester Bonding Yarn

Higher Yarn Mass for Defined Thermal-Bonding Zones

Our 150D polyester hot melt yarn is supplied in white with a nominal melting point of 110°C. It can be knitted into flat, hosiery, circular and warp-knitted structures before controlled heat activation.

Compared with 100D, the 150D specification contains 50% more nominal yarn mass at equal length. The final bonding result still depends on yarn placement, fabric construction, temperature, dwell time, pressure and cooling.

150D Polyester Hot Melt Yarn Specifications

Confirm the polymer, denier, melting point, color and processing route together when preparing the purchase specification.

Specified Product Identity

This product is polyester hot melt yarn rather than polyamide yarn. Keeping the material name consistent across the order, package label and sample record prevents confusion with nylon grades.

150D is the nominal linear density.
110°C is the nominal melting point.
White is the standard listed color.
100D is the adjacent listed specification.

When to Evaluate the 150D Grade

Use the denier as a controlled design variable, then confirm the completed textile through a production-line trial.

More Material per Length

150D introduces more polymer mass than 100D at the same yarn length. Stitch density and placement determine the actual amount used in each fabric area.

Visible Yarn Coverage

The thicker nominal specification may create different coverage and fabric hand. Check both before confirming the knitted construction.

Machine Feed Setup

Review feeder tension, yarn path, needle gauge and package unwinding with the actual machine rather than transferring 100D settings unchanged.

Yarn Packages and Production Context

Package format, winding condition and storage handling affect stable feeding during knitting trials and bulk production.

Trial Sequence for Thermal Activation

Establish the operating window with the intended companion fibers and finishing equipment.

Step 1

Define Placement

Set the courses, zones or layers where the 150D yarn will be introduced.

Step 2

Set the Trial

Record machine temperature, dwell time, pressure and line speed for each test piece.

Step 3

Cool the Fabric

Allow the activated structure to cool before checking bond formation and dimensions.

Step 4

Approve Results

Confirm appearance, hand feel and the required end-use test before bulk settings are released.

Knitting Applications

The yarn must be evaluated in the actual structure because equipment, stitch design and heat transfer conditions differ between production routes.

Flat KnittingFor shaped panels and engineered zones requiring thermal stabilization after knitting.

Hosiery KnittingFor selected courses or functional zones where the yarn can be placed during production.

Circular KnittingFor continuous knitted structures with a controlled post-knitting heating route.

Warp KnittingFor constructions with defined yarn paths, fabric tension and finishing conditions.

Sample-to-Bulk Checks

Match polymer, 150D size, color and melting point to the order.
Inspect winding condition and package integrity before machine loading.
Compare yarn feeding with the approved sample under recorded settings.
Check bonding after cooling under the agreed test method.
Retain an approved sample for incoming bulk-lot comparison.

Details for Quotation

Provide the required quantity, fabric construction, companion fibers, knitting machine, thermal process, bonding target, package preference and destination country.

150D Polyester Hot Melt Yarn FAQ

Is this 150D yarn polyester or polyamide? +

This grade is specified as polyester. Identify polyester on the order and sample record because polyamide hot melt yarn has a different material identity.

What does the 150D specification mean? +

150D identifies nominal linear density. It is a yarn-size value and does not independently specify bonding strength or the required machine temperature.

How does 150D compare with 100D? +

At equal length, 150D has 50% more nominal yarn mass than 100D. Compare coverage, feed behavior, hand feel and bonding contribution in the same fabric design.

Should the machine be set to 110°C? +

Not automatically. The nominal melting point is a material reference. Determine the equipment setting through trials using the intended fabric, heat source, dwell time and pressure.

What information is required for a quotation? +

Send the quantity, application, fabric construction, machine type, companion fibers, thermal process, target result, package preference and destination country.
