A textile tool part pair (15) consisting of two textile tool parts (16) and a method of equipping a textile machine with the aid of such a textile tool part pair (15) are disclosed. Each textile tool part (16) extends in a longitudinal direction (L) between a trailing end (21) and a leading end (22). Proceeding from the trailing ends (21) thereof, the textile tool parts (16) extend away from one another and counter to one another as far as the leading end (22). At the trailing ends (21), the two textile tool parts (16) of a common textile tool part pair (15) are interconnected by a predetermined breaking connection (45). The predetermined breaking connection (45) can be manually separated without tools, in particular by bending about a bending axis (A).

A slider spring for a slider used with a slider needle of a loop-forming textile machine includes a closing section for closing a hook opening of the slider needle, a connection section for connecting to a slider body, and a guide section for guiding the slider at a needle body. The slide spring includes at least one bead with a concave bead interior and a convex bead exterior. The slider spring is shaped and configured to be stacked against at least one other slider spring such that the convex bead exterior of the slider spring fits completely within the respective concave bead interior of the at least one other slider spring. A slider for a slider needle includes first and second slider springs as described. A slider needle includes a slider displaceable in a needle longitudinal direction relative to a needle body for opening or closing a hook opening.

A slide needle, comprising a needle body, which has a needle hook with two spaced-apart lateral hook surfaces. A slide is movably arranged on the needle body between an initial position (I) and a stitch knock-over position (II). The slide has two slide blades. A hook hole on a free blade end of the slide blades is formed by inner hole surfaces. In the stitch knock-over position (II), each inner hole surface lies against an associated lateral hook surface of the needle hook at a contact location and the contact area between the slide and the needle hook is reduced in a height direction (H).

A needle for a warp knitting machine, manufactured by means of an amorphous alloy injection molding process and comprising the following components: in parts by weight, 57.5-65.5 parts of zirconium, 11-16 parts of copper, 7-13 parts of nickel, 5-10 parts of titanium, 1-7 parts of aluminum, 1-7 parts of beryllium and 0.3-2 parts of yttrium. A method for manufacturing a needle for a warp knitting machine by means of an amorphous alloy injection molding process, comprising the following steps: (1) material mixing and smelting for manufacture into small blocks; (2) injection molding; (3) alloy opening removal; (4) thickness machining; (5) slotting; (6) polishing; and (7) electroplating. Beryllium and yttrium are added into amorphous alloy zirconium-based metal; beryllium can improve the toughness of a latch needle product, and has high fatigue limit and high wear resistance; yttrium powder can improve the strength, toughness and wear resistance of a latch needle blank.
