Thread trimming is one of the common processes in industrial apparel manufacturing. Cutting threads from stitched garments prior to garment finishing is a non-value added but unavoidable process. Number of helpers are hired for thread trimming job in garment factories. Manual thread trimming is time consuming and all trimmed threads can't be removed permanently from garments.
To reduce trimming labour and effort to some extent, factories use UBT machines. (Sewing machines mainly, lock stitch machines come with automatic thread trimming parts aka under bed trimmer). Though you use UBT machines in sewing, you may still need to trim threads from garments to get clean garments, as other machines used for stitching the garment may not have under bed trimmer and sewing operator may not be motivated to trim threads after stitching each garment.
Most factories practice manual thread cutting by hand trimmer (See below image). This manual process increases the chance of damaging garment pieces. It may increase number of defective garments in a lot. Therefore it is good to invest on automatic thread trimming machines. Other than trimming of stitching threads, one may need to trim embroidery threads and beading threads.
