Cad iad na lochtanna tipiciúla in iniúchadh fabraice cniotáilte?

Seo a leanas liosta de roinnt neamhfhoirfeachtaí a tharlaíonn go minic agus a fhaightear in iniúchadh fabraice cniotáilte. Is gnách go mbíonn na lochtanna fabraice seo mar gheall ar mhífheidhmiú meaisín cniotála, nó d'fhéadfadh lochtanna snátha nó ruaimniú fabraice míchuí a bheith mar thoradh air freisin, priontáil nó críochnú.

Defects in knitted fabric inspection

Barre – streaks or bands in the fabric, de bharr difríochtaí i méid snáth, teannas ar snátha nó fabraic, dath, luster nó crapadh, ó chuid amháin den éadach go dtí an ceantar in aice láimhe. The bands are horizontal and are found only in weft knit fabrics.

Birdseye nó Tucking Defect – unintentional tucking caused by a bent latch on the latch needle or by the needle not being raised to the proper height for the old loop then to be case off.

Boardy – very harsh or stiff hand, caused by stitches being too tight or yarn being too thick.

Broken Filaments nó Snáth –this defect is self-explanatory, which means one or more filaments or yarns are broken.

Cockled Fabric – fabric puckers and does not lie flat; caused by uneven stitches or uneven yarn size.

Drop stitch – an unknitted stich, caused by a stich being too loose or the yarn carrier not being set properly.

Float – unwanted miss-stitch(es) caused by needle(s) not raised to receive a new yarn.

Needle Line – lengthwise marks or lines in the fabric resulting from a wale which is tighter or looser than the others. This is caused by a needle being tight in the slot or from a defective sinker.

Press-Off – large hole in the fabric, caused by a yarn breaking at a particular feed so knitting cannot occur.

Run nó Ladder – a series of dropped stitches in a wale.

Skewing – design or line effect which is straight across in the fabric, but not perpendicular to the fabric edges.

Sleazy – term used to describe a flimsy or under-constructed knit fabric, one lacking in “body”.
