Sizing Machine is an apparatus designed to add size material to warp yarns before weaving

Sizing Machine is an apparatus designed to add size material to warp yarns before weaving, in order to stiffen and protect them from abrasion. Sizing is usually coated on the surface of the yarn through various physical processes.
An effective sizing machine should be operated correctly. All required parameters, including minimum sticking ends, stretch percentage, correct beam quality and moisture content must be monitored and managed.
Control system
A sizing machine's control system is responsible for monitoring and controlling various parameters, such as residual moisture levels, stretch tension, creel tension and squeeze roll pressures, temperature control of size box/drying cylinder temperatures as well as pressure in each chamber - this helps guarantee consistent quality beam sizing results.
Improved sizing stability, operating convenience and energy-saving performance are achieved via the Moisture Retention Monitoring System which automatically adjusts take-up speeds based on target moisture content values and automatically tests.
There are three available sizing methods and drying cylinder structures. Staggered up-and-down positions increase sheet yarn contact area for increased drying efficiency with lower steam consumption requirements.
Warp beams
Warp beams of a sizing machine serve as the loom beams necessary for weaving textiles, with their size dependent upon the count range of yarn to be processed. To ensure optimal results from your weaving machine, the warp size must correspond perfectly.
Unintentionally mis-sized warps will create issues when weaving. Care should be taken in sizing their warps in order to ensure they penetrate yarn rather than just coating it in liquid sizing solution.
An effective sizing recipe must contain low stretch percentage and high elongation at break to reduce short ends and ensure optimal sizing results.
Sow box
Sizing machines are used in textile mills to add size material to warp-yarns prior to weaving. The added material increases yarn's breaking strength while protecting it from abrasion and helping reduce hairiness of its fibers; typically made of polyvinyl alcohol or starch.
Sow boxes contain stainless steel tubs which house the sizing liquor and feature control panels to monitor its temperature. It is important that concentration of sizing liquor remain low in order to avoid thick layers forming inside of them and build-up within your sow box.
An SOW serves both as a contract agreement and project management tool, outlining workflow, goals, deadlines and expectations of both parties involved in a project.
Immersion rollers
A sizing machine is used to adjust the size of warp yarn. This machine consists of rollers partially submerged in sizing liquor that rotate and impregnate warp with size before drying it and winding onto a takeup beam.
The level gage in a cavity box containing sizing liquid can help determine consumption accurately; however, this does not account for changes caused by steam entering through its way into the box and increasing liquid level.
The results of NOVA analysis reveal that wet zone yarn tension, squeezing pressure, and speed of the sizing machine all have significant influences on size pick-up percentage; their interaction also has an enormous effect on its abrasion resistance.
Sizing liquor
Sizing liquor is used to prepare warp yarns so they can withstand mechanical stresses and strains experienced during weaving. The sizing process involves applying an adhesive agent directly onto each warp thread in order to bind them together and increase strength, reduce hairiness and increase abrasion resistance.
Sizing recipes depend on the quality parameters of the warp yarn, such as its number of thin places, neps, unevenness percentage, tensile strength and elongation at break.
Liquor bottles come in all sorts of sizes, from standard pints and half-liter bottles to magnums - having an understanding of these bottle sizes will enable you to better estimate your inventory needs.
Cooking vessel
Sizing mills often neglect preparing size mixture, yet this task remains crucial to production. Typically, cooking equipment is located close to the sizing machine so that gravity allows its paste to migrate toward its destination in the sizing box.
In a cooking vessel, water is measured using a graduated metallic scale and then ingredients are gradually added according to your size recipe. Proper preparation of sizing liquor is of utmost importance; should it become congealed while being made, no amount of heating and stirring can bring it back to an easily flowing state.
