Calculating Yarn Requirements for Weaving

Calculating Yarn Requirements for Weaving

A balanced fabric, where warp and weft threads are also visible, usually has PPE and PPI that are close to each other when you use the same thread in the warp and weft. If you want your weave to have a weft, which means your weft threads are more visible than your warp threads, you want your PUP to be significantly higher than your PPE. For chain weaving, you need a significantly lower PPI than your PPE. How to calculate the percentage of use in the weaving plant? A guide to calculations related to thread and fabric and all weaving processes. It includes the number of reeds, the width of the leaves, the maximum EPI for a given number, the density of the canvas, the percentage of setting, the reference factor of the fabric, etc. Hello, How to calculate the Leno/Bobin wire consumption for the required meters? I`ve already answered similar questions like this, but it might be a slightly different inclination. The first piece of information you need to know to calculate the web project feed is your web waste. This means the length of the chain that remains after you finish weaving – the amount used to tie or grind around the back apron bar, as well as the length of the back apron bar to the fur of the fabric where you cut the woven fabric of the loom. This distance can vary from 15″ to 30″ depending on the construction of your loom. Then, (this is important and is not usually considered part of loom waste), you need to add to this sum the amount of chain you used to attach to the front apron bar and wasted distributing the chain before you start weaving the real fabric. It could be about 10.” In hand-woven magazine projects, we allow at least 27″ for all loom waste. It`s a bit tight, so I usually allow 1 yd for all loom waste (you`re probably metric, so you`ll have to convert this to just under a meter). PPE You now need to calculate the number of wire ends you need.

By the set you discovered above, multiply the sett (number of ends per inch) by the total width of the project. It depends on the type of loom and the amount of thread lost through the deformation process (for beginners, there is a certain learning curve here). To calculate the waste of your loom, write down carefully the next time you weave a project! Deform and put on your loom as you would with any other project. Weave the chain from start to finish and stop it when the chain is close enough to the trees (or hoisted on a rigid tongue loom) so that you can no longer get a clean shed and continue weaving. Cut the chain of your loom and measure the extra thread left at the beginning and end of your project that you couldn`t weave on. This is usually referred to as “loom waste”, although this thread can be used as fringes. Once you know the average waste of your loom, you can use this number in the future. We recommend adding a little more to this number just so you have some air to breathe at the end of your chain.

I am looking for a web project thread calculation. How much yarn do I need to weave a project? So, in summary, here is the thread calculation of your web project: Warp: Loom Waste + ((Desired Length / (100% – Absorption) x Desired Width x PPE) Shot: (Desired Width x PPI x Desired Length) / (100% – Absorption) Why the cost of Suzuki warping machine is more than weaving loom weaving. The general rule is about 10% for balanced fabrics and more for weft fabrics. Even if you have a predetermined pattern, it`s a good idea to check if you have enough wire to complete your project. Absorption and shrinkage To calculate the length of the required curvature, take the length of your finished project and add 10% to 15% for absorption and shrinkage. Removing the chain depends on your wire and the string holder depends on your peaks per inch (PPI). If you`re not sure, 10-15% is a good rule of thumb. While everyone wants to jump straight into weaving, sampling is a big part of the creativity of a new web project and can save you time, money, and grief by figuring out what works and what doesn`t before weaving your entire project together. The amount of string you determine for sampling ultimately depends on you, but we recommend allowing at least a few centimeters. To calculate the amount of shooting, you need to know the width of the chain, the number of pickaxes per inch and the length of the weave.

Usually, I add ten percent to that number for shooting. (So for an 8″ wide chain woven with 20 peaks per inch for 65″: 8″ x 20 x 65″ = 10,400″ divided by 36″ / yd = 288 yd plus 10% = 317 yd. How we calculate the weight of the wire from the given quality. For example: 31/1×31/1/7366-71 ” Next, you need to consider the absorption and removal of the threads and weaving structures that you have selected. Usually, I allow 10% for cotton and other spun yarns that do not shrink much when woven into simple weaves or similar structures. If the threads shrink sharply or you use a weaving structure that decomposes sharply, you need to add to this number. But let`s start with 10%. Table of dimensions of the Shot thread Remember that you also need thread to weave the photo. If you also use the same wire for shooting, you will need about the same amount to complete the two table runners – 1.8 lbs. YPP yarn is usually sold by weight, number of pounds or grams. The rod measurement is sometimes displayed on the trim cone, or you can ask your yarn supplier how many yards per pound there are in the wire you bought. The hemp wire shown above has 1500 yards per pound (ypp).

So you would be 1365/1500 = 0.9 lbs. Need wire for the chain. Since there is always a considerable amount of weaving waste in a web project, it is usually advisable to produce more than 1 item at a time. I`m looking for a book or website that helps you calculate the thread you need. I did my last weaving factory 30 years ago and I would like to do it again. Thank you for the answer and best regards. When you set out to design your own web project, you may be wondering how many meters of wire you need for your project. It depends on many factors, such as your set of chains (or PPE), your tape waste, the final length of your part, the finished width, and any additional strings you need for sampling or fringes. Luckily for you, we`ve put together a simple, free calculator to help you. Just enter the above details and it will calculate the total length of your warp and the total amount of weft wire you need. EPI stands for End Pick per Inch, while PPI stands for Pick Per Inch, how to calculate the firing requirement on two layers of Loom Waste fabric You need an extra length of chain to be able to attach the ends of the chain to the back and front of the loom.

This is called loom waste. Loom waste is usually around 27,” but I add a full yard for weaving waste. This gives me a few extra inches of chain to sample and play with new designs or colors. How to calculate fabric weight per meter with 40 warp, 60 shots, reeds 58, Pick 56, width 48 inches Can you please suggest the formula and how to use it For a really useful book that covers this and much more, you should consider The Weaver`s Companion! How to count the selection of Dobby design fabric with a pick counter? Total deformation Each end of the chain will have a length of 3.5 meters and you will need 390 ends. To calculate the total length of the string, multiply the total length of the string x by the total number of ends. Construction: 30×20 + 70D / ………….×60 =61″ GSM = 139 PPE = ???? How to drop the weight of the thread and heal the eye size of the slecect wire. Please simple formula send me Waight from Warp in kg i.e. meters to kg Formula Hope that helps! I realize that you need to convert ends per inch to ends per centimeter, etc., but the process will be the same. How to calculate the number of crosses/repetitions of the given fabric 2 x 46″ = 92″ + canvas waste 36″ = 128″ or 3.5 yards. Project width Next, you need to know the desired width of your project. Add 10% – 15% for absorption and removal.

To change the number and number of threads/inches, the same density of the 1.Count fabric becomes 4%2. Thinner dyed accounts will get a maximum of 6% rudeR I surfed online for more than 3 hours today, but I`ve never discovered an eye-catching item like yours.
