and history2. Selection criteria of spotting chemicals3. Factors for spotting
Washing Machines Types: Automatic, Semi-automatic,
wringer style Programmed cycles: Eg. Perma-press
FIBER CYCLE TIME
WATER TEMP
AGITATION & SPIN SPEED
WOOL 1-3 MIN 110-120 DEG F
SLOW
COTTON & LINEN
10-12 MIN 120-140 DEG F
NORMAL
MANUFACTURED & DURA PRESS

LAUNDRY PROCEDURES Sorting Selecting washing time Water temperature Pre-treating spots & stains Selecting laundry products Pre- treatment for soil lines formed
around perma-press areas like oncollars, cuffs
STAIN REMOVAL Longer a stains stays on a garment ,
harder is it to remove the same. Composition of the stained fabric. Fabric Structure Testing of the fabric for its
compatibility with the stain remover Please look in to the hand out
provided to you that lists down a number of stains and the remedy for their removal
Drying Time and temperature settings Line drying or automatic dryer Heat sensitive fabrics, natural rubber
elastics….caution---Read Care label Durable press and synthetic fibre
fabrics to be removed immediately after completion of drying cycle---why?
PRESSING Checking temperature on an
inconspicuous part of the garment Steam press or slightly damp Dark colored fabrics of all fibres to be
pressed on the reverse side or over a press cloth to avoid shine
Pressing of wool fabrics Pressing of silk Pressing of textured fabrics What is a needle board used for pressing
Needle Board
A flat board consisting of a rigid top nap formed by short,
blunt wires imbedded upright in a base.
-To avoid crushing the pile or nap of the fabric which is
placed face down against the needle board during press-
ing or steaming.
-To prevent pile fabrics from matting and flattening.
-To prevent the impressions of a seam ridge from appearing on the
face or right side of pile fabrics when pressed.
-To press velvet, velveteen, corduroy, fleece, Ultrasuede,
fake fur, pile and napped fabrics
Commercial laundering Sorting as per color, fiber content,
degree of soil etc. Washing with detergents and added
alkali at 125 F to 165 F. Chlorine bleaching at 160F, 3-5 mins 3-4 rinses Acid sour and blueing Starch addition
Why acid sour?Neutralize, remove iron stains, destroy excess
bleach, kill bacteriaUse of acetic acid, Sodium bisulfite, Sodium
acid fluoride and oxalic acid Laundering of white goods vis a vis, light
colored vis s vis dark colored goods Commercial laundering of Wool and silk
garments-Neutral soaps and detergents used, no added alkali, gentle agitation, acid sour
Dry Cleaning Origin----1825 Agents: Benzene, per chloro ethylene Reusing solvents Checking for spots, stains Wet cleaning is treating fabrics with
small amounts of water to remove soil
Storage of Textile products Longer wear may be effected if given
a chance to “rest” between uses Folding items at different place and
not at the same crease line Clean before storage Attack of moth or fungi easier on
soiled fabrics, darkening of spots/stains
Never to store with pins left in garments
Moth repellents for wool
Storing historic costumes & textiles
Made of natural fibres Should be stored away from light and in
acid-free conditions Avoid use of plastic bags to avoid off-
gassing Ideal: 70 deg F, 60% RH Wool and silk garment not to be
laundered except by an expert historian Loose dust removed by vacuum keeping
synthethic netting in between
