Textile lab

The laboratory padder is used for resin finishing application of knitted and woven fabrics. The pressure is adjustable and the padder speed is approximately 2 m/min.

Main advantages

• Laboratory padder for resin finishing application of knitted and woven fabrics.
• Padder speed: 5 rpm = 2 m/min.
• Pressure adjustable (0.1 - 0.6 kg/cm² = 1 - 6 bar) for different applications resulting in different pickups of finishing agents.
• Depending on pressure setting (normally 0.1 - 0.3 kg/cm² = 1 - 3 bar) and fabric specification (weight and structure), pick up is between 65 % and 85 %.
• Width: 400 mm, diameter: 125 mm (LP) respecively 200 mm (LDP)
• Padding mangle made of NBR rubber or Hypalon.
• Solid and compact table design.
• All stainless steel design.
• Plug and play (only electrical and air connection needed).
• Excellent price value ratio.

• Laboratory Padder LP

Cotton dyeing

Dyeing The most commonly used processes for imparting color to cotton are piece dyeing and yarn dyeing. In piece dyeing, which is used primarily for fabrics that are to be a solid color, a continuous length of dry cloth is passed full-width through a trough of hot dye solution. The cloth then goes between padded rollers that squeeze in the color evenly and removes the excess liquid. In one variation of this basic method, the fabric, in a rope-like coil, is processed on a reel that passes in and out of a dye beck or vat. Yarn dyeing, which occurs before the cloth is woven or knitted, is used to produce gingham checks, plaids, woven stripes and other special effects. Blue dyed warp yarns, for example, are combined with white filling yarns in denim construction. One of the most commonly used yarn dyeing methods is package dyeing. In this system, yarn is wound on perforated cylinders or packages and placed on vertical spindles in a round dyeing machine. Dye solution is forced alternately from the outside of the packages inward and from the inside out under pressure. Computers are used increasingly in dyeing processes to formulate and match colors with greater speed and accuracy.

Instructions on Basic Fabric Dyeing

All you need is a fabric dyeing or tie-dye starter kit, some cotton sewing fabric, and some household supplies. This book evolved from my days as a fabric dyeing instructor.

Pre-Wash your fabric. Use HOT water and 1/4 cup Synthrapol or Dharma Professional Textile Detergent (PTD) per machine load. This will remove any dirt, grease, or other gunk. Use Enzyme detergents to remove starch. Fabrics treated with permanent press, conditioners, sizing or water proofing, etc are not recommended. This is a very important step. Pre-washing really can make all the difference. We even recommend always pre-washing so called PFD (Prepared For Dyeing) fabrics, as you never know "where they've been". Even fingerprints can cause blotchy dyeing.

5 Easy Steps for DYEING fabric:
1. Gather supplies
2. Mix Dye and hot water in a bowl
3. Add fabric and mix periodically for one hour (+)
4. Drain and rinse fabric
5. Wash and dry fabric in a machine

* Plastic Bowl- large enough to hold 3-4 onesies or a couple T-shirts.
* Mixing Spoon - use one you don’t care about. It will be dyed along with the fabric.
* Clothing for Dyeing - Today I’m dyeing 4 things: some white onesies, a clearance t-shirt from Old Navy (which I’ll sew some sort of applique on top of), and a green onesie that I dyed a year ago but hated the color.
Have an old onesie with milk stains? Or pink onesies that once belonged to your daughter? Dye them for your baby boy!
