When Do You Need a Continuous Bleaching Range?
A continuous bleaching range is the open-width line where pretreatment chemistry is padded onto fabric in a steady stream. The LMH035 is specifically a cold pad batch (CPB) line: it pads pure cotton fabric in pretreatment to thicken the size liquor and build the desizing effect, then delivers the cloth to a large-roll A-frame for batch dwell.
Cold pad batch pretreatment is the energy-light route for woven cotton. Instead of steaming and washing at high temperature on a long continuous range, you pad the chemical, wind the cloth onto a roll and let it react at room temperature as the roll rotates - which is why an open-width entry and a large-roll A-frame exit define the machine.
If you run pure cotton woven fabric and want a continuous scouring and bleaching / desizing route that is gentle on energy and suited to medium batches, this cold bleaching range is the machine to look at.
Core Parameters & Technical Data
Application: padding of pure cotton fabrics in pretreatment, to thicken the size liquor and achieve the desizing effect.
Machine speed: 30-75 m/min.
Working width: 1800-3200 mm.
Total installed power: 10.6 kW.
Cloth entry: open-width entry.
Cloth exit: large-roll A-frame exit - the padded cloth is batched on a roll on the A-frame for the cold dwell stage.
These figures set the width, speed and power envelope of the line; match the working width to your widest cotton fabric and the speed to your target output.
How to Choose the Right Bleaching Range
Start with working width. The 1800-3200 mm range covers most woven cotton goods; specify your widest fabric plus margin.
Confirm the process is truly cold pad batch. If you need high-temperature continuous scouring and bleaching with steamer sections, a full continuous bleaching machine differs from a CPB line - tell us your pretreatment recipe.
Check speed against output. 30-75 m/min defines line pace; plan how many meters per hour you need and whether batching dwell time fits your schedule.
Look at entry and exit format. Open-width entry plus a large-roll A-frame exit is the CPB arrangement - verify your cloth can run open-width and that your plant can handle the A-frame rolls.
Match power and utilities. A total power of 10.6 kW tells you the electrical envelope; confirm your site supply and the chemistry handling for padding.
Choose a factory that understands the padding chemistry as well as the mechanics, since pad pickup and liquor concentration drive the desizing result.
Common Mistakes Buyers Make
Confusing cold pad batch with a steamer bleaching range. A CPB line pads and batches at room temperature; it has no steamer sections. If you need hot continuous bleaching, specify a different line.
Under-sizing working width. The 1800-3200 mm range is generous, but a narrow choice later blocks wide fabric - measure your real widest cloth.
Ignoring the batching stage. Cold pad batch relies on controlled dwell on the A-frame roll; if the roll winds badly or the fabric creases, desizing turns out uneven. Plan the A-frame and batch rotation.
Treating the line as generic bleaching. The LMH035 is for pure cotton padding and desizing buildup; running heavy synthetics on it is a mismatch.
Buying on price alone. Pad pickup uniformity and liquor circulation determine desizing quality - a factory that also supports pretreatment process know-how is worth more.

Frequently Asked Questions
What is a cold pad batch bleaching range?
It is an open-width continuous pretreatment line that pads chemistry onto pure cotton fabric, then winds the cloth onto a roll on an A-frame to dwell at room temperature. It builds the desizing effect without high-temperature steaming.
What fabrics is the LMH035 used for?
It is mainly used for padding pure cotton fabrics in pretreatment, to thicken the size liquor and achieve the desizing effect.
What are the working width and speed?
Working width is 1800-3200 mm, machine speed 30-75 m/min, with a total installed power of 10.6 kW. It uses open-width entry and a large-roll A-frame exit.
Is this a continuous bleaching machine with a steamer?
The LMH035 is a cold pad batch line: it pads and batches at room temperature for desizing. If you need high-temperature continuous scouring and bleaching with steamer sections, tell us and we will advise on the right line.
What exit format does it use?
Open-width entry and large-roll A-frame exit - the padded cotton is batched on the A-frame roll for the cold dwell stage of the process.
