Sequins, glitter film and rhinestones are the trims most often used to add highlights to womenswear, eveningwear, childrenswear and stage costumes, yet they are fixed by three quite different processes: sequins are sewn (or pre-set on a hot-fix film), rhinestones are heat-pressed through a glue backing, and glass beads are usually hand-sewn. Choose the wrong process and the first wash starts shedding pieces, while childrenswear can fail a small-parts test outright.

This guide runs in five parts: separating the three bead and stone families, choosing between sewing and heat-press, matching press parameters to substrate, validating wash durability, and finally the acceptance criteria and checklist you can paste into a quotation request.

1. Separate the Three Families First

Type Main material How it is fixed Main risk
Sequin, sewn Aluminised or pearlescent PET film Machine-set or hand-sewn with a single needle Sharp edges; one broken thread sheds a whole run
Hot-fix sequin film Sequins pre-set on a hot-melt film Heat press or transfer in one pass Edges lift after washing; the motif turns stiff
Rhinestone Glass, acrylic or resin Glue backing, pressed with a heat press Glue fails and stones drop; scorch marks on fabric
Glass beads Glass or acrylic beads on beading thread Mainly hand beading High labour, heavy piece; needle detection needs a shard protocol

2. Sew or Press: Start From Fabric and Care

Keep the decision order fixed: how much press heat the fabric tolerates, how the finished garment will actually be cared for, and how much hand work the quantity and labour budget allow. Reversing it — picking the process by price first — is how projects fail at bulk stage, once fabric burns or dry cleaning dissolves the glue.

  • For silk, chiffon, lace and mesh, prefer sewing or a low-temperature glue at 110–130 °C; high heat leaves press marks or even melt holes.
  • On knits, sweatshirts and cotton canvas a full motif is far more consistent as hot-fix film than as single-needle setting, and it avoids stitching that snaps when stretched.
  • Denim, canvas and leather tolerate a higher glue temperature (150–170 °C) with strong adhesion, once you confirm the leather finish will not discolour.
  • For childrenswear, especially under three years, favour sewing and avoid any piece that can be pulled off; pressed stones must pass the small-parts testing of the target market's toy and childrenswear rules.
  • Hand beading on couture cannot be replaced, but put the hours and the per-piece bead count into the quote up front, or later re-beading will blow the schedule.

3. The Pressing Trio: Heat, Pressure and Time

Hot-melt backings fall broadly into standard, high-strength and low-temperature grades, and each must match the fibre and the stone. There is no universal setting; the ranges below are a sampling starting point that must be confirmed on the actual fabric and glue before bulk.

Parameter Typical range Note
Temperature 130–170 °C Use the lower end for silk, stretch and coated fabrics; low-temperature glue must stay under 130 °C
Pressure 2–4 bar Too little pressure leaves glue partly unmelted, so stones drop in patches
Time 8–20 seconds Larger areas need longer; overshooting scorches or squeezes glue out
Cooling Cool fully before folding and packing Bagging while warm causes sticking and shifting: a defect the moment the bag opens
💡 Tip: adhesion depends on the bond between the glue backing and the fibre, not on the stone. Mesh, coated fabric and water-repellent finishes shed stones most easily, so sample on the real fabric and test under the care conditions before confirming bulk.

4. Wash Durability: Fix the Care Method First

Bead and stone durability must be verified under the conditions printed on the garment's care label, not the supplier's habit. Put the care method in the request, and the supplier can choose the right process; fixing the process first and then changing care means redoing the batch.

  • Washing: follow ISO 6330 at 40 °C, then inspect visually and record pieces lost per hundred, lifted edges and glue marks.
  • Dry cleaning: perchloroethylene is the harshest test on hot-melt, dissolving most standard glues; for dry-clean-only styles switch to sewing or a strong low-temperature glue and validate separately.
  • Abrasion and stretch: after handling tests, check for broken threads and missing pieces, especially at plackets and cuffs where friction concentrates.
  • Childrenswear: run the small-parts tension test required by the target market and log any sequin or stone that can be pulled free as a failure.

5. Acceptance Criteria and a Quotation Checklist

  • Loss rate: agree the pieces lost per hundred and how it is judged (visual plus hand check after washing), and state the rework and debit terms if exceeded.
  • Placement drawing and net pattern: supply both, with distances and tolerances to neckline, placket and hem, rather than locating by verbal description.
  • Material and glue in writing: the supplier should state the film material, stone type, glue grade and maximum temperature, as the baseline for any later substitution.
  • Needle and shard control: glass beads and metal-set stones must pass needle detection, with an agreed sweep-and-record routine for broken shards.
  • Retained samples: keep one before-wash and one after-wash sample per lot so disputes can be re-tested on the same batch instead of argued from photos.
