Boltzmann machines are trained using an objective function that is evaluated by sampling quantum states that approximate a Gibbs state. Classical processing is used to produce the objective function, and the approximate Gibbs state is based on weights and biases that are refined using the sample results. In some examples, amplitude estimation is used. A combined classical/quantum computer produces suitable weights and biases for classification of shapes and other applications.

The invention relates to a rope made of textile fiber material, comprising a rope core and a sheath surrounding the rope core, wherein the sheath, an intermediate sheath located between the sheath and the rope core and/or a reinforcement located between the sheath and the rope core comprise(s) a twine of excess length, the twine of excess length being formed in that it comprises at least a first yarn and a second yarn which are twisted together, the first yarn having a greater length than the second yarn, measured in an untwisted state of a unit length of the twine. In a further aspect, the invention relates to a method of manufacturing a twine of excess length for the above-mentioned rope.

A method of creating a soft and lofty continuous fiber nonwoven web is provided. The method includes providing a first molten polymer and a second, different molten polymer to a spinneret defining a plurality of orifices and flowing a fluid intermediate the spinneret and a moving porous member. The method includes using the fluid to draw the first and second molten polymer components, in a direction toward the moving porous member, through at least some of the plurality of orifices to form a plurality of individual continuous fiber strands. The method includes depositing the continuous fiber strands onto the moving porous member at a first location to produce an intermediate continuous fiber nonwoven web, and intermittently varying a vacuum force applied to the moving porous member and to the intermediate web downstream of the first location and without the addition of more continuous fibers and without any heat applied.

An actuator fiber is made of a thermoplastic resin and has a coil spring shape. A spring index D/d of 1.7 or more when an average diameter of a coil portion is represented by D and a fiber diameter is represented by d. A glass transition point measured by a differential scanning calorimeter may be 150° C. or lower.

Aspects herein are directed to using a space-treating process to apply functional finishes to a yarn and incorporating the treated yarn into a textile and/or a garment to impart engineered functional properties to the textile and/or garment.

A method for producing a textile product (I), (II), comprising at least two synthetic pile threads (P1), (P2) having a different pile height, so that a predetermined design is formed, in which the synthetic pile yarns (P1), (P2) are manufactured by extrusion from the same raw material, according to production processes which only differ from each other by a different setting of one or several process parameters of their respective extrusion processes, so that they have a different shrinking capability, and in which the textile product (I), (II) is subjected to a heat treatment which causes the pile yarns (P1), (P2) to shrink differently. Also such a method for producing synthetic textile yarns (P1), (P2) having a different shrinking capability.

The device (1) comprises a first roller (3) rotatable about a first rotation axis (3A) and a second roller (5) rotatable about a second rotation axis (5A), parallel to the first rotation axis (3A). The two are in mutual contact and define between them a yarn passage (7) and at least of them is motorized. The device further comprises 5 guide members (9) defining a feed path of at least a yarn (F; F1, F2, F3, F4), associated with the yarn passage (7) between the first roller (3) and the second roller (5). The guide members (9; 13) are movable with respect to the rollers (3, 5) in a direction substantially parallel to the first rotation axis (3A) and to the second rotation axis (5A), so as to take the yarn path temporarily outside the mutual contact 10 area between the rollers.

A process for manufacturing a yarn includes twisting the yarn in a first direction for a predefined number of twists. The method also includes, after the predefined number of twists, twisting the yarn in a second direction for a predefined number of twists, the predefined number of twists for the second yarn is same as the predefined number of twists for the first yarn. The twisting of the yarn in the second direction creates an air bed within the yarn's fibers.
