Hollow fibres have single or multiple holes, a normal crimp and are supplied “dry” or with a silicone layer. HCS stands for Hollow Conjugated Siliconized. These fibres are actually made from two different polyester polymers and are therefore bi-component. This chemical property and a special production process gives them a 3D crimp to provide a higher puff. Hollow fibres are generally used for high volume applications, to improve thermal and acoustic insulation and, for example, to improve the moisture wicking properties in beds and upholstery. We also stock hollow fibres with a dtex of just 1.6 or 10 holes for special-purpose requirements.
Polyester staple fibres
Polyester staple fibres are one of the most widely used synthetic fibres in the world. They are made from polyethylene terephthalate (PET), a polymer produced by the polymerisation of ethylene glycol and terephthalic acid. PET fibres are known for their excellent strength, durability and stretchability, making them suitable for a wide range of applications.
In the world of textiles, polyester staple fibres are used to make a variety of products, including clothing, upholstery and home textiles. They are often blended with other fibres such as cotton or wool to create fabrics that combine the best properties. For example, a polyester-cotton blend offers the strength and durability of polyester and the softness and comfort of cotton.
One of the key benefits of polyester staple fibres is their high resistance to wrinkling, shrinkage and stretching. This makes them ideal for use in clothing and other products that are frequently used and worn. They also have excellent colour fastness, which means that the colour of the fabric will not fade or bleach even after repeated washing.
Another advantage of polyester staple fibres is that they are easy to maintain. They are machine washable and suitable for tumble drying and can be ironed on low heat. They are also very abrasion resistant, making them ideal for products that are subject to frequent wear, such as upholstered furniture, carpets and rugs.
In addition to their excellent properties, polyester staple fibres are also environmentally friendly. They are made from petroleum, a renewable resource, and are recyclable. They also use less energy to produce than other synthetic fibres, making them an eco-friendly option for those who care about the environment.
Polyester staple fibres have several advantages when used in nonwoven products:
- Strength and durability: Polyester staple fibres are known for their excellent strength and durability, making them ideal for use in nonwoven products that are subject to frequent use and wear.
- Versatility: Polyester staple fibres can be used to produce a variety of different types of nonwoven products, including filter media, geotextiles and medical products. They can also be blended with other fibres such as cotton or wool to create a fabric with specific properties.
- Cost-effectiveness: Polyester staple fibres are a cost-effective choice for nonwoven products as they are cheaper to produce than other synthetic fibres. This makes them an ideal choice for companies looking to produce high quality nonwovens at an affordable price.
- Resistant to moisture and bacteria: Polyester staple fibres are moisture resistant, making them ideal for nonwoven products that are exposed to moisture, such as wipes, disposable gowns and medical products. With an appropriate finish, they are resistant to bacteria and fungi, making them ideal for use in medical and personal care products.
- Easy to process: Polyester staple fibres are easy to process and manufacture, making them an ideal choice for companies that want to produce nonwovens in large quantities. They can be easily shaped, bonded and matted, making them a versatile choice for nonwoven products.
In summary, polyester staple fibres are a versatile and practical choice for a wide range of applications. They offer excellent strength, durability and stretch resistance, as well as good colour fastness and ease of care. Whether you are looking for a strong raw material for a durable fabric for clothing, upholstery or home textiles, polyester staple fibres are an excellent choice.
