General Requirements for Clothing Production

General requirements

  • Fabric and accessory materials should be of high quality and meet customer requirements. Bulk goods should be confirmed by customers or inspected by an authoritative certification agency.

  • Accurate color matching of styles.

  • The size should be within the allowable error range.

  • Excellent workmanship.

  • The product should be clean, tidy and have a good surface.

The packaging should be beautiful, accurately matched, the cardboard box size should be suitable and suitable for long-distance transportation.


  • Unless the customer has special requirements, the minimum color fastness requirement for goods should be:
    1. Water-washing color fastness:

    A) Color change rating of single washing color fastness should be 3-4 levels
    B) Color stain rating of sticking color fastness should be 3-4 levels

      2. Friction color fastness:
      A) Dry friction rating should be 3-4 levels
      B) Wet friction rating should be 2.5-4 levels

      3. Light fastness rating should be 4 levels

  • Accurate color matching required, and the color difference between bulk fabric and confirmed color should be within 3.5 levels and confirmed by the customer.

  • The lining fabric should have the same color and the color difference should not be less than 3.5 levels.

  • The fabric component ratio should be accurate, and the yarn density should be uniform. The woven fabric should meet the density requirements of the customer, and the weight error range of knitted fabric should be within ±5%.

  •  If there are no specific regulations for size changes, all fabrics must be controlled within the following ranges: after 5 general washings, the maximum error angle in each direction should be within 3%; after 3 dry cleanings, the maximum error angle in each direction should be within 2%.

  • For pure synthetic fiber fabrics, flame retardancy tests are exempted. Natural and artificial fiber fabrics must be tested; 2*6 inches of fabric are subjected to a 16-micron flame for 1 second, and the burning time is calculated. It is acceptable if it exceeds 7 seconds without delayed combustion, or it is unqualified if it is less than 7 seconds.

  • Materials for export orders must not contain azo dyes, and the factory should carry out item-by-item or phased testing according to the order requirements.


  • Metal buckles and eyelets should not be made of iron. All metal accessories should not contain nickel, and plastic accessories should not contain cadmium.

  • Woven labels and jacquard tapes should have clear patterns, neatly cut edges, and no broken yarns.

  • Printing products should be clear, non-penetrating, and non-degumming.

  • Sprayed products should be firmly painted without damage.

  • Elastic bands and elastic cords should have good elasticity.


Strictly check all details based on the customer's sample or style drawing (this work should be completed by the salesman during the pre-production inspection). All salespersons should require the technical department or factory to submit all pre-production samples of the color group before producing bulk goods.

Appearance requirements

  • The placket should be straight, flat, and consistent in length. The front pull should be flat and consistent in width, and the lining should not be longer than the placket. The zipper lip should be flat, even, and not wrinkled or warped. The zipper should not wave. The buttons should be straight, even, and have equal spacing.

  • The stop-sew seam should be straight, not flipping, and the width should be consistent on both sides (excluding special requirements).

  • The split should be straight and not disturbed.

  • The pocket should be square, flat, and the pocket mouth should not be cut.

  • The pocket cover, patch pockets, and paste bags should be square, flat, and consistent in front and back, high and low, and size. The lining pockets should be consistent in height and size, square, and flat.

  • The collar gap size should be consistent, the collar bone should be flat, and both ends should be tidy. The collar should be round and flat, with suitable elasticity, and the outer opening should be straight without curling. The bottom collar should not be exposed.

  • The shoulder should be flat, the shoulder seam should be straight, and the width on both sides should be consistent. The stitching gap should be symmetrical.

  • The sleeve length, cuff size, width should be consistent, and the sleeve hem should be consistent in height and size.

  • The back should be flat, the seam should be straight, and the waistband should be horizontally symmetrical with suitable elasticity.

  • The hem should be round, flat, and the elastic band and rib should be consistent in width. The rib should match the stripe.

  • The lining of each part should be appropriate in size and length, without sagging or protruding.

  • For the woven tapes and jacquard back straps that are sewn on the outside of the clothes, the patterns on both sides should be symmetrical.

  • The filling should be flat, evenly pressed, with neat lines, and the front and back pieces should be aligned.

  • If there is velvet on the fabric, it should be oriented in the same direction.

  • The heat-seal tape should be flat, without wrinkles, and firmly bonded.

  • If the fabric is coated with white glue, there should be no white glue seepage at the needle holes, and the sewn thread should be wet-oiled (the best method is to use a small piece of cotton wetted with oil, clamped at the over-thread hole of the machine table, and let the thread slide from inside the cotton).

  • If the style is sealed from the sleeve, the sealing length should not exceed 8 cm, the sealing should be consistent, firm, and tidy.

  • For fabrics with stripes or grids, the stripes should be accurately aligned.


If there are no special regulations, measure the clothes in a natural state when placed flat on the tabletop. The allowable error range should be specified according to the clothing fabric required by each factory. (Note: If a large error is found before production, all efforts should be made to improve it and minimize the error range.)


(according to customer requirements, the following points must be noted)

  • Threads and stains must be cleaned thoroughly.

  • Garments should be ironed flat, without leaving any iron marks; they should only be placed in the bag after the steam has dispersed.

  • If a cloth dampened with water is used to wipe the garment, it should be allowed to dry before being packed.

  • Hang tags should be hung in the specified location, and stickers should be pasted in the specified position.

  • Plastic bags must not be damaged.

  • The ratio should be correct, not mixed, and not short.

  • The sealing part of the paper box should be padded to prevent the clothes from being scratched when opened (if there is an inner box, the pad should be placed in the inner box, not in the outer box; when distributing the pads, the number of inner boxes should also be taken into account).

  • The size of the paper box should be moderate. After opening the box, the clothes should be flat. If the paper box is damaged or the paper is too soft or damp during the inspection, the paper box should be replaced immediately.

  • The contents of the box mark should be filled in clearly, and no content should be omitted.

  • The box should be firmly tied.
