A method of making a loop fastener product features knitting, such as by circular knitting, a pile yarn and one or more ground yarns to form a stretchable knit fabric having loops of the pile yarn extending from a knit ground, with the ground yarns including polymers of differing melt temperatures. The knit fabric is then held in a desired state while the fabric is set by first applying sufficient heat to cause the lower melt temperature resin to flow into interstices of the fabric ground, and then allowing the fabric to cool. The cooled fabric ground is less stretchable in two orthogonal directions after setting than before setting, has a greater air permeability after setting than before setting, and has hook-engageable pile loops extending from bound interstices.

A sensing apparatus for yarn feeder may comprise a yarn feeder and a tension controller. The tension controller has an elongated sensing block installed therein, and a horizontal extending board is connected to the sensing block. An operating rod is mounted on a middle upper surface of the extending board at one end and upwardly sticks out of the tension controller to pivotally connect to a tension pulley at the other end. A yarn wound on a winding wheel of the yarn feeder is configured to couple with the tension pulley. At least an impedance sensing piece is attached on a surface of the sensing block, and a deformable hole horizontally penetrates through the sensing block. When the sensing block is pressed or pulled, the tension controller can obtain the tension value of the yarn and further calculate the torsion value of the yarn feeder.

A method and system detect and remotely manage sensors and/or devices for feeding textile and/or metallic yarns on textile machines. Each textile machine includes an electronic control unit electrically connected to the sensors and/or feeding devices for receiving identifiers associated with a sensor and/or feeding device, and data and operating parameters representing a sensor and/or feeding device operating state. A first communication system is associated with the electronic control unit. Wireless communication between the electronic control unit and a portable electronic device is by a second wireless communication system with a display interface. The electronic control unit transmits the identifiers to the portable electronic device. The portable electronic device processes the identifiers to generate menus with selectable entries associated with the textile machines. Each menu represents the number/type of sensors and/or feeding devices installed. The main menu is displayed with selectable entries on the portable electronic device display interface.

Knitted fabric is produced with a knitting machine and a roving drawing and strengthening unit. A roving supply unit provides a roving and an auxiliary thread supply unit provides an auxiliary thread. A stretching unit receives the roving and the auxiliary thread. A spinning nozzle following the stretching unit in a roving conveying direction forms a fiber strengthening segment by applying compressed air and an end thread gripping roller pair rotatable in opposite directions provided downstream from the spinning nozzle device in the roving conveying direction delimiting the fiber strengthening segment. A soft knitted fabric is formed by guiding an auxiliary thread through an auxiliary thread gripping roller pair with an adjustable rotational speed before the roving and auxiliary thread enter the stretching unit. The gripping roller pair holds the auxiliary thread so that the auxiliary thread is subjected to tension of no more than 2 cN.
