Down proof lining fabric is a fabric that is designed to prevent down feathers or fill from escaping through the garment's inner lining. The fabric is tightly woven or treated to create a barrier that keeps the feathers contained within the fabric. This type of lining fabric is commonly used in jackets, vests, and sleeping bags. It is also sometimes used to make insulated quilts.
When choosing a Down Proof Lining Fabric, it is important to choose a fabric that is both durable and easy to maintain. This will help ensure that the lining remains in good condition throughout its lifetime of use. Additionally, the lining should be breathable to keep the wearer comfortable while wearing the garment. If possible, the lining should be the same weight as the outer fabric. This will help reduce any bulk and weight that the garment may have.
There are many different types of lining fabrics available to choose from, and each has its own advantages and disadvantages. Some lining fabrics are made of natural materials, while others are made from synthetics. In addition, lining fabrics can be either crease resistant or non-crease resistant. The crease resistance of a lining fabric is usually determined by the amount of starch that is used in its construction.
A lining fabric's pore size can also be a significant factor in its ability to provide insulation. A lining fabric with larger pores can trap more air than a lining fabric with smaller pores. Additionally, a fabric with a high density weave can improve its insulation properties.
In order to determine the optimum pore size for down-proof fabrics, further studies should be conducted on the effect of fabric construction factors. The pore size distributions of fabrics woven with different yarn counts, fiber types and texture should be studied to identify the best lining fabric for down-proof applications.
The permeability of a down-proof fabric can be improved by using a special finish or treatment. A polyurethane or silicone coating can be applied to the fabric to create a film that helps to prevent down from penetrating through the fabric. Alternatively, the fabric can undergo a hot calendaring process, which compresses the components of the fabric and increases its resistance to down penetration.
Another option for down-proofing fabric is to use a glue sprayer to apply PUR adhesive to one side of the fabric. This method can be more effective than calendering and can produce an excellent bond with the fabric. In addition, the process can be performed in-line with the manufacturing of the lining fabric, which reduces manufacturing costs and time. The resulting lining fabric can be used in any textile application that requires down-proofing, including clothing and sleeping bags. It is especially suited to situations where the lining will be exposed to moisture and heat.
