HEATSOFT Far-Infrared Thermal Yarn

HEATSOFT is a compact-spun far-infrared thermal yarn made from 80% acrylic, 15% nylon and 5% wool. The product combines ceramic FIR particles with a fluffy high-bulk structure, which gives socks, knitwear, sweaters and warm accessories a soft, warm hand feel. Standard counts are 1/28 and 1/35.

A standard count may not fit every fabric plan. For that reason, custom counts and colors are available, while trial orders start at 1 kg per color. The mill can then check the shade, hand feel and knitting behavior before arranging a larger order.

How HEATSOFT is built for thermal use

HEATSOFT uses ceramic FIR particles together with a lofty yarn structure. As a result, it is intended for winter textiles where warmth and a soft hand feel both matter. Its compact-spun construction can be checked on the buyer’s own knitting machine during sampling.

Because far-infrared claims may form part of a buyer’s product approval, inspection or test documentation is available for review. Before using a performance claim on a finished product, request the current document and confirm that it applies to the selected specification.

HEATSOFT uses ceramic FIR particles for its far-infrared thermal function. In contrast, WARMPLUS-R moisture-absorbing heat-generating yarn generates heat by absorbing moisture. Choose the yarn that matches the buyer’s required function.

Selecting 1/28 or 1/35 for sampling

The published standard counts are 1/28 and 1/35, and custom counts are also available. Before requesting a sample, send the intended product, machine setting and target fabric weight. As a result, the sample and quotation can refer to the same specification.

Buyers searching for a 1/28 wool-nylon thermal yarn should note the full HEATSOFT blend. Acrylic is the main component at 80%, while nylon accounts for 15% and wool for 5%. If a customer tech pack specifies a different blend or count, confirm the requirement before color development begins.

If color matching is required, include the shade reference with the inquiry. Then confirm the count, color standard, packing and lead time before production. A small trial can be used to review the shade, hand feel and knitting result.

What to check during a knitting trial

First, run HEATSOFT on the machine planned for the finished product. During the trial, check yarn feeding, lint, breakage and the evenness of the knitted surface. After knitting, compare the shade, hand feel and fabric appearance with the approved requirement.

Next, record the count, color reference and machine setting used for the approved sample. This makes a repeat order easier to specify. If inspection or test documents are part of the approval process, review them at the same stage.

Order quantities and quotation

The quotation depends on count, color standard, order volume and shipping terms. Because these details change from one order to another, the page does not publish a fixed price.

Order type	Typical volume	Purpose	Quotation basis
Sampling or trial	1-20 kg	Shade, hand feel and machine testing	Confirmed yarn specification
Regular wholesale	20-200 kg	Repeat production	Count, color and order volume
Bulk project	200 kg or more	Seasonal or larger production programs	Confirmed specification and shipping terms
Custom development	Case by case	Special count, color or packing	Confirmed development requirements

For an exact quotation, send the target count, shade reference, application and expected volume. In addition, mention any packing marks or document requirements at the start of the inquiry.

Packing and delivery

Standard packing is 25 kg per carton or plastic bag. If required, the order can carry SKU labels, color labels and carton marks suited to the buyer’s receiving process.

Stock orders normally dispatch within 1-2 days after confirmation. Custom production normally takes 3-15 days after confirmation. Therefore, projects with a fixed delivery date should confirm the count and shade before the production schedule is arranged.

Small trial orders can be shipped by courier. Larger orders can go by air or sea, depending on the required schedule and order volume.

Information to include with an inquiry

A complete inquiry lets the supplier check the request without asking for the basic details again. Include:

Required count and expected quantity
Color standard or shade reference
Intended product, such as socks, sweaters or other knitwear
Packing and carton mark requirements
Required inspection or test documents
Destination and preferred shipping method

Before placing the order, reconfirm the current technical data and commercial terms.

FAQ about HEATSOFT far-infrared thermal yarn

What is the exact fiber blend of HEATSOFT?

HEATSOFT contains 80% acrylic, 15% nylon and 5% wool. It is produced with a compact-spun process and has a fluffy high-bulk structure.

Does HEATSOFT contain only wool and nylon?

No. Acrylic is the main fiber at 80%, while nylon accounts for 15% and wool for 5%. Therefore, buyers searching for a 1/28 wool-nylon thermal yarn should compare the full 80/15/5 composition.

What is the role of ceramic FIR particles in HEATSOFT?

Ceramic FIR particles form part of the yarn’s far-infrared thermal construction. Together with the fluffy structure, they are used to give winter textiles a soft, warm hand feel. If a project needs documented far-infrared performance, request the current test information for review.

Which HEATSOFT count should I sample first?

HEATSOFT is available in standard 1/28 and 1/35 counts. The choice depends on the intended product, machine setting and target fabric weight. Custom counts can also be discussed when neither standard option fits the project.

Can I order a custom HEATSOFT color before bulk production?

Yes. Custom colors are available, and the trial MOQ starts at 1 kg per color. However, send the shade reference before sampling so the requested color can be confirmed.

What documents can I request for HEATSOFT?

Inspection or test documentation is available for buyer review. Before ordering, ask which current document applies to the selected count, color and product requirement.
