The present invention provides a polyamide (preferably Nylon 66) yarn for weaving or knitting clothes articles which have a cooling effect on the skin of the wearer. The yarn contains an inorganic additive (preferably Titanium dioxide) in an amount of between 0.3 and 3.0 wt % and is characterized by a low crimp modulus and a flat cross section.

Cooling polyamide yarn

The invention provides a polyamide yarn and fabric for making clothes articles which have deodorizing effect and which enhance warming and drying on the skin of the wearer.

Polyamide fabric enhancing body warming

Provided is a process for manufacturing a polyamide yarn exhibiting good dyeability, while utilizing polyamide waste. The recycled polyamide yarn with a high waste polymer content is used for making quality articles by a low cost method, which is further friendly to the preservation of the environment.

Process of making recycled polyamide yarn

Process for manufacturing a fabric having distinctive and sharp differentially colored patterns or designs, which process comprises the steps of: (a) producing a first and a second polyamide, said polyamides having different concentrations of amine groups; (b) producing a first and a second polyamides having different concentrations of carboxyl end-groups and sulfonate groups; (c) producing a first yarn from said first polyamide and a second yarn from said second polyamide; (d) making a fabric having first surface areas defined by said first yarn and second surface areas defined by said second yarn; and (e) chemically dyeing said fabric in a dyeing bath comprising at least one anionic (acid) dyestuff and at least one cationic (basic) dyestuff, whereby said first yarn and therefore said first surface areas are dyed predominantly by said anionic dyestuff and said second yarn and therefore said second surface areas are dyed predominantly by said cationic dyestuff.

Process for making polyamide textile articles bearing designs in different colors

A process is provided for making a yarn with improved properties, such as lowered susceptibility to picks and snags. The yarn consists of a spandex core that is tightly covered with a nylon fiber, which tight covering is achieved by heat treatment. A knitted fabric is further provided, that is made of yarn consisting of a spandex core and a nylon fiber, which has low susceptibility to picks, as well as to tears during its production and its use.

Spandex covered tightly with shrinkable nylon and process for producing it

A process for the manufacturing of a differentially dyeable yarn includes the steps of: a) producing two polymers having a different concentration of amine end-groups; b) spinning yarns from said two polymers; and c) producing a yarn by intermingling said spun yarns made from said two polymers, in texturing, or draw twisting, or draw winding processes.
