Start a Circular Knitting Underwear Garments Making Plant



(123) Circular Knitting Underwear Garments Making Plant
Traditional underwear garments were made by sewing two pieces of fabrics (bottom of under-paints and under-paints) together. The multi-layer sowing on bottom of under-paintssite made them uncomfortable to wear. The skin is easily damaged by abrasion with the sowing edges, and suffered from less ventilation from by thicker bottom of under-paints. For texture fitting, both inner and outer layers are synthetic fabrics with less elasticity and coverage; nonetheless, better appearance. Synthetic fabrics were used for better appearance.
We made no-bottom paints-paints are with the advantage of one-shape knitting type. Reduce wearing uneasiness from abrasion by removing sowing edge on the bottom of under-paints. In addition, better appearance without trace of sowing edge on heap while dressed in fitted slacks. Our products gives you more options in dressing slacks, praised by consumers in Taiwan & Japan, and with vast potential on international markets.
The inner layer adopts a special tower texturing with soft/fine/comfortable long fibers, better ventilation and better sweat-absorbing properties. Not only comfortable for wearing but also preventing germ growth. They are definitely good for personal hygiene and health. These products have with excellent elasticity, better fitting without tightness and coverage without folded-edges & dislocations. The new Y-hip and concertina products are with advantages of enhanced curve and abdominal shrinkage effects. The Y-hip product, by special design, at center of the hip knitted for bundle, good ventilation net partition, naturally fit on hip curve plus bilateral bundle, amazingly shape up the hip. Paints’ surface pattern structure was knitted in one time. Use electronic yarn feeder (made-in-Germany) to knit one-shape, concertina and no-bottom under-paints. They are cable to shrink waist and belly with even bundle, and not uncomfortable by excessiveness.
The whole process of knitting machine includes one-shape knitting, organizing, checking, shape setting and finish sewing. The manufacturing technology and equipment are mostly developed and/or made by us to simplify the manufacturing process and to reduce the manufacturing cost.
Wearing the underwear and under-paints made of cotton and/or nature fiber can absorb and expel skin moisture, sweat and secretion. It protects skin hygiene, and causes no adverse effect.

2 General processing information
2.1 Description of manufacturing process:

Material→Knitting machine output→Dyeing→Shape Setting→Cutting→Sewing→Packaging→Outgoing of finished products
Use nature yarn as the material by patented equipment (no-bottom structure underwear knitting machine) to knit one-shape patterned Y-hip concertina and terry raw cloth. Through low temperature vat to dye, patented shape setting machine to set the shape, and to put in order. The Vertical cutting machine cuts tens of raw clothes each time. Use sewing machine to sew waistband or lace on, and pack them for outgoing.
