Navigating the fabric world can be exciting and challenging, especially regarding materials like PUL (Polyurethane Laminate).
PUL fabric, renowned for its waterproof properties, is a staple in crafting essential items like cloth diapers, wet bags, and bibs.
However, determining which side to sew on is a critical aspect often overlooked. In this guide, we delve into the nuances of PUL fabric, unraveling the mystery behind its right and wrong sides.
Understanding this distinction is paramount for ensuring the functionality and aesthetic appeal of your sewing projects. Join us as we explore the significance of sewing on the correct side of PUL fabric.
What Is PUL Fabric?
PUL (Polyurethane Laminate) fabric is waterproof with a knit fabric layer bonded to a thin polyurethane laminate. It is commonly used in sewing projects requiring waterproof properties, such as cloth diapers, wet bags, and bibs.
The knit fabric side, often printed or colored, is right, while the opposite side features a shiny plastic layer, typically transparent or white.
This versatile fabric is durable, easy to clean, and breathable, making it ideal for various applications where moisture resistance is essential.
PUL fabric provides functionality and aesthetic appeal, making it a popular choice among DIY enthusiasts and professionals.
Which Side To Sew on PUL Fabric?
When sewing with PUL (Polyurethane Laminate) fabric, always sew on the side with the knit fabric, typically printed or colored.
This side is known as the right side. Conversely, the wrong side features a shiny plastic layer, usually transparent or white.
Sewing on the right side ensures the preservation of the fabric’s waterproof properties and maintains the desired appearance of the finished item.
Additionally, sewing on the right side prevents damage to the waterproof layer, ensuring the longevity and functionality of projects like cloth diapers, wet bags, and bibs. Thus, always sew on the side with the knit fabric when working with PUL fabric.
Why Is It Important To Know Which Side To Sew on PUL Fabric?
It is essential to know which side to sew on when working with PUL (Polyurethane Laminate) fabric for several reasons:
Maintaining Waterproofness
PUL fabric is designed to be waterproof, with the polyurethane laminate providing the barrier against liquids.
Sewing on the wrong side can compromise this waterproofness, leading to leaks or reduced effectiveness in items like cloth diapers, wet bags, or bibs.
Aesthetic Considerations
The right side of PUL fabric typically features the knit fabric layer, often printed or colored, intended to be visible on the finished item.
Sewing on the wrong side can result in a less attractive appearance, as the shiny plastic layer may be exposed or visible.
Functionality
Sewing on the correct side ensures that the fabric behaves as intended. The knit fabric side is more straightforward to sew, while the plastic layer on the wrong side may cause issues such as skipped stitches or difficulty handling.
Longevity of the Project
Sewing on the right side helps maintain the integrity of the fabric and its waterproof properties over time. It reduces the risk of premature wear or damage if the wrong side is exposed to wear and tear.
How Do You Determine the Right Side of PUL Fabric?
Determining the right side of PUL (Polyurethane Laminate) fabric is typically straightforward, as it often has visual cues that differentiate it from the wrong side.
Here are some methods to determine the right side of PUL fabric:
Visual Inspection
The right side of PUL fabric usually features the knit fabric layer, which may be printed or colored with designs, patterns, or solid colors. In contrast, the wrong side typically has a shiny plastic layer, often clear or white.
Texture
The right side of the PUL fabric may feel softer and smoother due to the presence of the knit fabric layer. In contrast, the wrong side may feel slightly rougher or have a texture resembling plastic.
Printed Information
Sometimes, manufacturers print information or branding on the selvage (the finished edge) of the fabric. This printing is usually done on the wrong side, helping to identify the right side by the process of elimination.
Previous Knowledge
If you purchased the fabric from a reputable source or manufacturer, they may provide information about the right side. This can be useful if the visual cues are not immediately apparent.
Water Test
While less common, some crafters suggest conducting a water test to determine the right side of PUL fabric.
Sprinkling a small amount of water onto the fabric can help identify the side that repels water, indicating the presence of the waterproof layer characteristic of the right side.
How To Sew With PUL Fabric? Tips for Waterproof Sewing Success
Sewing with PUL (Polyurethane Laminate) fabric can differ slightly from sewing with regular fabrics due to its waterproof and somewhat sticky nature.
Here are some tips to help you sew with PUL fabric more effectively:
Use a Sharp Needle
Use a new needle specifically designed for stretch fabrics, such as a ballpoint or stretch needle. These needles will help prevent skipped stitches and damage to the fabric.
Use Polyester Thread
Polyester thread is more durable and resistant to moisture than cotton thread. It also has less friction, which can help prevent skipped stitches.
Adjust Your Machine Settings
Set your machine to a slightly longer stitch length than usual. This can help prevent the fabric from bunching up or puckering as you sew. Also, reduce the tension on your machine slightly to accommodate the thickness of the fabric.
Consider Using a Walking Foot
A walking foot can help feed the fabric evenly through the machine, reducing the chances of the fabric shifting or stretching as you sew.
This is particularly helpful when sewing multiple layers of PUL fabric or along curved edges.
Use Clips Instead of Pins
Pins can leave permanent holes in PUL fabric, compromising its waterproof properties. Instead, use clips or wonder clips to hold the fabric pieces together while you sew.
If you must use pins, place them within the seam allowance so they won’t puncture the waterproof layer.
Avoid Ironing Directly on The PUL
The plastic layer on PUL fabric can melt when exposed to high heat. If you must press seams, use a low heat setting on your iron and place a pressing cloth or scrap fabric between the iron and the PUL to protect it.
Practice on Scrap Fabric
If you’re new to sewing with PUL fabric, it’s a good idea to practice on scrap pieces first to get a feel for how the fabric behaves and how your machine handles it.
FAQs
What happens if I sew on the wrong side of the PUL fabric?
Sewing on the wrong side of PUL fabric, which has a shiny plastic layer, can compromise the waterproofing and durability of the fabric. It may also affect the appearance of the finished item.
Can I use pins when sewing with PUL fabric?
It’s generally recommended to avoid using pins with PUL fabric as they can leave permanent holes that may compromise its waterproof properties. Instead, consider using clips or wonder clips to hold the fabric layers together.
How do I prevent the fabric from sticking to the sewing machine with PUL fabric?
Using a walking or Teflon foot can help prevent the fabric from sticking to the sewing machine. Adjusting the machine settings and using the correct needle and thread can contribute to smoother sewing.
Can I pre-wash PUL fabric before sewing?
It’s generally recommended to pre-wash PUL fabric before sewing to remove any manufacturing residues and pre-shrink the fabric. However, avoid using fabric softeners or harsh detergents, as they can affect the fabric’s waterproof properties.
How do I store and care for items made with PUL fabric?
Store items made with PUL fabric in a cool, dry place away from direct sunlight to prevent deterioration of the waterproof layer. When washing, use mild detergent and avoid bleach or fabric softeners. Line drying or using a low heat setting in the dryer is recommended.
To Recap
In sewing with PUL (Polyurethane Laminate) fabric, the importance of discerning the right and wrong sides cannot be overstated.
Seamstresses and crafters rely on this knowledge to preserve the fabric’s waterproof integrity and elevate the visual allure of their creations.
By adhering to the principle of sewing on the side with the knit fabric, enthusiasts ensure the longevity and functionality of essential items like cloth diapers, wet bags, and bibs.
As our exploration comes to a close, let us carry forward this invaluable insight, empowering us to embark on future sewing endeavors with confidence and precision, knowing that the right side always leads to exceptional results.
