A recently filed patent (Publication Number: US20230286246A1) describes a thermally fusible sheet material that can be used in various textile applications. The material consists of a backing ply made of a textile material and a bonding compound structure. The bonding compound structure includes at least one polyalkylene succinate as a hotmelt adhesive. Polyalkylene succinate is a type of polymer that is derived from succinic acid and various polyols.
The patent claims specify several characteristics of the thermally fusible sheet material. Firstly, the bonding compound structure may also contain polybutylene succinate, another type of polymer derived from succinic acid. Secondly, the bonding compound structure does not include any conjugated diene-based polymers modified with polar functional groups. Additionally, the bonding compound structure may include polyalkylene succinate hotmelt adhesive with specific melt flow index (MFI) values and melting points.
The patent also mentions that the bonding compound structure can contain other hotmelt adhesives, apart from polyalkylene succinates. These additional adhesives can be selected from biodegradable and/or compostable thermoplastic polymers. The thermally fusible sheet material can be in the form of a two-ply structure, with a lower layer directly on top of the sheet material and an upper layer on top of the lower layer.
The patent further describes a process for producing the thermally fusible sheet material, which involves applying the bonding compound structure using various application methods such as spreading, powder point, paste print, hotmelt, and inkjet methods.
The thermally fusible sheet material can be used in the production of various textile products, including interlinings, linings, and outer fabrics. It is particularly suitable for the production of biodegradable and/or compostable textile products. The material can be used as an interlining in men's and women's clothing, as well as in clothing accessories, needlework, sewing, and padding with adhesives.
The patent also mentions that the thermally fusible sheet material can be used in the production of different types of clothing, including men's clothing, women's clothing, children's clothing, and various types of outerwear. It can also be used in the production of clothing accessories such as hat bands and hat reinforcements.
Overall, the patent describes a thermally fusible sheet material with specific characteristics and applications in the textile industry.
