A thermal insulation curtain made of wool felt generally provides more insulation than one made of synthetic fabric. Wool felt has natural insulating properties, as it is able to trap air and regulate temperature effectively. It is also more breathable and can absorb moisture, making it a better insulator. Synthetic fabrics, on the other hand, may not provide the same level of insulation and can be less effective at regulating temperature. **

Fabric glue is designed to remain flexible and pliable in order to maintain the natural drape and movement of the fabric. If the glue were to harden, it would make the fabric stiff and uncomfortable to wear. Additionally, the flexibility of the glue allows the fabric to stretch and move without cracking or breaking the bond. This flexibility also makes the fabric glue more durable and resistant to wear and tear. **

Fabric can be attached to other fabric using various methods such as sewing, gluing, or using fusible interfacing. Sewing involves using a needle and thread to stitch the fabrics together, while gluing involves using fabric glue to bond the fabrics. Fusible interfacing is a type of adhesive material that can be ironed onto fabric to attach them together. To remove fabric from fabric, you can simply cut the stitches or seams holding them together, or use a seam ripper to carefully undo the stitching. **

When choosing a fabric glue, it is important to consider the type of fabric you will be working with and the intended use of the item. Some popular fabric glues include Aleene's Fabric Fusion, Beacon Fabri-Tac, and Dritz Unique Stitch. These glues are known for their strong bond, flexibility, and ability to withstand washing. It is recommended to test the glue on a small, inconspicuous area of the fabric before applying it to the entire project to ensure compatibility. **

Yes, in the 1930s, electrical wires with insulation made of fabric were commonly used. These wires typically had a cotton or silk fabric covering to insulate the conductive wire inside. While not as durable or long-lasting as modern plastic insulation, fabric-insulated wires were widely used in homes and buildings during that time period. Over time, advancements in technology led to the development of more efficient and safer insulation materials for electrical wires. **

Yes, in the 1930s, electrical cables with insulation made of fabric were commonly used. These cables typically had a cloth covering, such as cotton or silk, to protect the wires inside. While fabric insulation was eventually replaced by more durable and fire-resistant materials like rubber and plastic, it was widely used during the early 20th century. **

Insulation should be done before plastering. Insulation helps to regulate the temperature inside a building and reduce energy costs, so it is important to install it before the walls are plastered. Plastering over insulation helps to create a smooth and even surface for the walls, ensuring that the insulation is properly covered and protected. Additionally, installing insulation before plastering can help to prevent any potential damage to the insulation material during the plastering process. **

A double needled nonwoven fabric is used as impact sound insulation under laminate flooring to reduce the transmission of impact noise, such as footsteps or dropped objects, from the floor above. The fabric is placed between the subfloor and the laminate flooring to absorb and dampen the impact energy, thereby reducing the sound transmitted through the floor. The double needled construction of the fabric provides enhanced density and thickness, which further improves its sound insulation properties. Overall, the fabric helps to create a quieter and more comfortable indoor environment by minimizing the impact noise associated with laminate flooring. **
