- Agree the success measures before the trial, not after
- Change one thing at a time and keep a control beam
- Measure weaving performance, not just the size box
- EcoSize-CXW-111 is formulated and manufactured by Seamens Enterprises in Pakistan; dosing is confirmed by trial
Warp sizing is one of the cheapest places in a weaving mill to lose money quietly. A beam that is under-sized breaks on the loom, and one that is over-sized costs chemicals and desizing effort. The only way to know what works on your yarn and looms is a planned trial. This guide sets out the steps, using EcoSize-CXW-111 as the example product.
What is EcoSize-CXW-111?
EcoSize-CXW-111 is a premium all-in-one sizing agent for warp yarn, supplied as a white granular powder in 25 kg bags. It is formulated and manufactured by Seamens Enterprises in Pakistan using imported premium raw materials, and is used for cotton warp in the Ne 6 to Ne 40 range. Its benefits include lower overall chemical cost than conventional multi-chemical recipes, high adhesion on polyester blends, minimal foam in the size box and one-bag mixing instead of several separate chemicals.
Dosing is confirmed by trial on your yarn, which is exactly what the steps below are for. Read the full EcoSize-CXW-111 guide.
Step 1: What should you decide before the trial starts?
Decide the success measures before the trial starts: which yarn count, which looms, which weaving efficiency and quality targets, and what result would make you switch. Without agreed measures, any result can be argued either way.
| Decision | Example |
|---|---|
| Yarn and construction | One cotton warp count in the Ne 6 to Ne 40 range on one set of looms |
| Primary measure | Warp breaks per loom hour or weaving efficiency |
| Secondary measures | Size add-on, hairiness, shedding in weaving, fabric quality at inspection |
| Decision rule | Switch only if the trial matches or beats the control on the primary measure |
Step 2: How do you set up a fair comparison?
Run the trial beam alongside a control beam from your current recipe, on the same yarn lot and the same looms. Change one thing at a time, so a difference in results can be traced to the sizing agent.
- Same yarn lot for the trial beam and the control beam.
- Same looms and weaving conditions where possible.
- One change only: the sizing agent, not the machine settings as well.
- Realistic beam size: a trial too small hides production problems.
Step 3: How do you run the size box trial?
Prepare the size liquor as agreed with the Seamens technical team, record every setting, and sample the size box at set intervals. Recording is the part most trials skip, and it is what lets you repeat a good result.
- Agree the recipe and mixing procedure with the technical team.
- Record temperature, concentration, squeeze pressure and machine speed.
- Take size box samples at the start, middle and end of the beam.
- Label the beam clearly as trial or control.
Step 4: What should you measure at the loom?
Measure weaving performance on the trial beam and the control beam over the same period: warp breaks, stops, efficiency and fabric quality. The loom is the real test of a sizing agent.
| Measure | Where to record it |
|---|---|
| Warp breaks and stops | Loom monitoring or shift log |
| Weaving efficiency | Production report for the trial and control beams |
| Shedding and fly at the loom | Floor observation and housekeeping notes |
| Fabric quality | Grey inspection report |
| Desizing result | Pre-treatment observations on the trial fabric |
Step 5: How do you decide, and what comes next?
Compare the trial with the control against the decision rule you wrote in step 1, then repeat the trial on a second beam to confirm consistency. A single good beam is encouraging; two consistent beams are evidence.
- Compare the primary measure against the control.
- Check the secondary measures and the desizing result.
- Repeat on a second beam, ideally a week later.
- If it passes, agree pack sizes, lead time and supply with Seamens.
