Needle (machine knitting)

A booked element used for intermeshing needle loops; there is normally one needle for each needle wale.bearded needleA needle having an extended terminal hook or beard which can be flexed to close the hook. The beard returns to its original position when the force is removed.spring needleA needle having an extended terminal hook or beard which can be flexed to close the hook. The beard returns to its original position when the force is removed.carbine needleA needle similar in shape to a bearded needle but with the beard shielded by a shoulder on the stem.
Note: The needle may only be lapped in one direction for the yarn to pass under the beard. A presser is not necessary as the needle is self-acting, the shoulder passing the loop on to the beard. The needle has a limited use, mainly in crochet-type machines.compound needleA needle in which the hook and hook closing parts are separately controlled.two-piece needleA needle in which the hook and hook closing parts are separately controlled.double-ended needleA needle having an operative hook at each end.latch needleA needle having a terminal hook closed by a pivoting latch. Its knitting acion is self acting since the fabric loop pivots the latch and allows the loop to be cleared from the open hook or knocked over the closed hook depending on the direction of needle movement.

Needle (needlefelt)

A barbed needle mounted] in a needleloom, (see needleloom (nonwoven)) to cause fibre reorientation and entanglement during needling.

Needle (sewing)

Ashaft-like element used for sewing, normally pointed at one end with an eye for thread or yarn.
Note 1: Needles for machine sewing are manufactured, normally from steel, with a great variety of point shapes, different diameters and surface finishes according to the intended end-use. Though usually straight, they may be curved (see needle, curved below).
Note 2.. A wide variety of hand-sewing needles is similarly available. Again, the design depends on the materials to be sewn and other operational and end-use considerations.
Note 3.. Generally speaking, machine sewing needles have the eye at the pointed end; handsewing needles have the eye at the opposite end.needle, curvedA needle with a curved blade used in some overedging and in blindstitch machines. Ill hand sewing, curved needles are sometimes used when the back of the material being sewn is not easily accessible.needle, double-pointedA needle with points at both ends and an eye midway between.
Note: This needle is used to form simulated hand stitching, Stitch Type 209.needle, straightA needle with a straight blade

Needle (tufting)

All instrument for inserting pile yarn tufts into a pre-made substrate. As in a sewing machine needle, the eye and the point are at the same end. The needle is grooved on one side, to take the yam, and chamfered on the other side to lead the looper to pass between the needle and the yam.(sub category of basic components tufting machine (carpet))

Needle bar

A rigid bar, running the width of the tufting machine and in which the tufting needles are mounted at fixed intervals. The needles may be in line (straight needle bar) or in two rows with alternate needles in separate rows (staggered needle bai.).(sub category of basic components tufting machine (carpet))

Needle Bed

Flat metal plate with slots at regular intervals in which the knitting needles slide on the knitting machine.

Needle damage

Damage occurring to the material during the stitching/seaniing process. There are many causes, attributable to the sewing conditions, the characteristics of the sewing needle, and the material hem. sewn. (See also seam damage.)

Needle feed

A feed mechanism in which the feeding of the material is accomplished or assisted by the needle which moves forward by one stitch whilst penetrating the material.puller feed A feed mechanism situated behind the presser foot and consisting of one or more rollers, at least one of which is driven, in contact with the material.(sub Category of feed mechanisms(sewing))

Needle gauge (sewing machine)

The distance between the points of any two adjacent needles on a multiple needle machine.

Needle Loom

A machine for bonding a nonwoven web by mechanically orienting fibers through the web. The process is called needling or needlepunching. Barbed needles set into a board punch fiber into the batt and withdraw leaving the fibers entangled. The needles are spaced in a nonaligned © 2001 Celanese Acetate LLC arrangement. By varying the strokes per minute the advance rate of the batt the degree of penetration of the needles and the weight of the batt a wide range of fabric densities can be made. For additional strength the fiber web can be needled to a woven knit or bonded fabric. Bonding agents may also be used.

Needle loop

The upper curved portion of a knitted loop.(sub Category of Knitted Loop)

Needle plate (sewing machine)

That part of the bed of the sewing machine which has openings for the needle and for feed dog penetrations, and which provides localised support for the material. The openings vary in size and shape, depending on the sewing requirei-neuis.

Needle positioner

An automatic device on a sewing machine which ensures that the needle will stop either 'in' (needle down) or 'out' (needle up) of the fabric as required.

Needle Set-Out

A term that refers to long periods of time when certain needles are removed from the knitting cycle. The process is used to make sweater cuffs.

Needle Slot

A groove that houses a needle in the cylinder or dial of a circular-knitting machine or the needle bed of a flat-bed machine.
