The present invention relates to a process for producing a compacted material comprising the steps of providing a powder material and a polymer binder, simultaneously or subsequently feeding the powder material and the polymer binder into a high speed mixer unit, mixing the powder material and the polymer binder in the high speed mixer unit until formation of a compacted material, and reducing the temperature of the obtained compacted material below the melting point or glass transition temperature of the polymer binder.

The disclosure generally relates to filaments and in particular, filaments for use in fused filament fabrication to prepare 3D printed articles. The filaments comprising a polymer composition, said polymer composition comprising: a) about 5 wt. % to about 60 wt. % of a thermoplastic polymer A having a melting peak temperature greater than 40° C.; b) about 95 wt. % to about 40 wt. % of a thermoplastic polymer B having a melting peak temperature greater than 20° C.; c) optionally from about 0.1 to 3 wt. % of a viscosity modifier; wherein: the melting peak temperature of thermoplastic polymer A is at least 20° C. greater than the melting peak temperature of thermoplastic polymer B; thermoplastic polymer A is dispersed in thermoplastic polymer B; and the polymer composition has a melt index of at least 0.1 g/10 minutes using a 10 kg weight measured according to ASTM D1238-13 at a temperature which is less than the melting peak temperature of thermoplastic polymer A and which is greater than the melting peak temperature of thermoplastic polymer B.

Fibrous elements, such as filaments and/or fibers, and more particularly to fibrous elements that contain a non-hydroxyl polymer, fibrous structures made therefrom, and methods for making same are provided.

The present disclosure provides a fabric, a preparation method thereof and clothing formed therefrom. The preparation method includes the following steps: obtaining bio-based synthetic fiber chips from textile waste materials; obtaining extruded filaments from the bio-based synthetic fiber chips by adopting a spinning solution; and weaving and interlocking the extruded filaments with bio-based elastic fibers to obtain the fabric. The prepared fabric is obtained from the textile waste materials, so that waste recycling is realized, and the pollution of the textile wastes to the environment is avoided. The spinning solution is adopted in the preparation process of the fabric, so that the opacity and hydrophilicity of the fabric can be enhanced.
