Nonwovens (1/2 meter wide line)
- Spunbond
- Bicomponent Spunbond
- Meltblown
- Bicomponent Meltblown
- Meltblown Nanofibers
- Spunbond spinning process development using 5” wide spin pack (sans forming and takeup)
- Smooth roll calendering
- Engraved roll calendering
Filament
- Filament Yarns
- Staple Yarns
- UOY Yarns
- POY Yarns
- FDY Yarn
- BCF
- Bicomponent Yarns as above
- Tricomponent Yarns as above
- Monofilaments
We have literally hundreds of cross sections available (many available on the nonwoven line) including Sheath/Core, Side by Side, Shaped Filaments, Segmented Pie in solid and hollow, Islands in Sea, Concentric Rings, and many more. We have polymer drying and testing equipment as well as some of the most experienced and innovative fiber spinning technicians and engineers in the world.
NanoMeltblown (1 meter wide line)
- 1.0 meter wide good fabric (1.2 meter wide untrimmed)
- supplied on 10 gsm area bonded Pa 6-6 substrate (Cerex®), customer’s substrate or no substrate
- 200 - 2000 nanometer (0.20 - 2 microns) average fiber diameter available
- Almost any meltblown grade polymer up to 300 deg C spinning temperature can be run - 0.25 - 14 gsm
Since this line is cost prohibitive to run for small lots, Hills is offering to sell small quantities of standard samples on a $ / meter basis. Contact Hills for current $/meter pricing at jhaggard@hillsinc.net
Hills’ Standard NanoMeltblown Fabric Sample Specifications:
- supplied on 10 gsm area bonded Pa 6-6 substrate (Cerex)
- 400 nanometer average fiber diameter
| Standard samples | Minimum order |
| 14 gsm PP | 50 meters |
| 3.1 gsm PP | 100 meters |
| 2 gsm PP | 150 meters |
| 1 gsm PP | 200 meters |
Custom NanoMeltblown Fabrics Samples
- PP basis weight between 0.25 and 14 gsm – Minimum order 500 meters
- PP NanoMeltblown 0.25 – 14 gsm applied to your substrate - Minimum quantity 500 meters
- Note: Your substrate must be very porous to insure good NanoMeltblown fabric quality. Customer substrates will be tested and approved before production.
- Other meltblown grade polymers up to 300 deg C extrusion temperature – Minimum order $10,000.00
- Fiber size average between 200 nanometers and 2 microns – Minimum order $3,000.00
Small Lot Polymer Sales
We keep a wide array of polymers in our inventory and can sell small lots. There are some polymers we always have in stock and some that are available on a lot by lot basis. This also includes color master batches and certain additives.
Contact us to discuss your needs. We are enthusiastic about helping you with your project.
