Glossary

Uniform fabric terms: P

The vocabulary that turns up on spec sheets, quotations and tender documents, defined in a line or two. Where a term deserves more than that, it links to the guide that covers it properly.

P

Packing list
The document listing what is physically in a shipment, roll by roll, with numbers, lengths, gross and net weights and carton or bale marks. Customs and the buyer's receiving team both reconcile against it, so a packing list that does not match the rolls delays clearance regardless of whether the cloth is right. Read the guide on Packing list
Panna
The trade word for fabric width, used across Indian fabric markets. Quoting a rate without stating the panna makes the price meaningless, since a wider cloth yields more garments per metre. Read the guide on Panna
Pantone TCX
The cotton-based version of the Pantone colour reference system used for textiles, supplied as dyed cotton swatches. A TCX number names a target colour; it does not guarantee that a given fibre and construction can reach it, which is what the lab dip decides. Read the guide on Pantone TCX
Paraxylene
The petrochemical, refined from crude oil naphtha, that PTA is made from, which makes it the first link in the polyester cost chain a fabric buyer ever feels. It is traded internationally in dollars, so a crude move reaches a poly-viscose quote through paraxylene long before it reaches the loom.
Payment terms
The line on a quotation that says how the order value is split and when each part falls due. Common structures are advance and balance, full advance, letter of credit and telegraphic transfer; the split is agreed per order and per buyer relationship rather than fixed across mills. Read the guide on Payment terms
Peak season surcharge
A temporary addition to container freight rates applied by carriers when demand runs ahead of available space, typically in the run-up to a major buying season. Like other surcharges it sits outside the base rate, so a freight quotation held open across a peak can still land higher than the figure quoted. Read the guide on Peak season surcharge
Performance security
Security furnished after a tender is awarded, usually as a bank guarantee, and released only once the last consignment is accepted. Because it stays lodged for the contract term, it is working capital committed for the whole programme. Read the guide on Performance security
PFAS
Per- and polyfluoroalkyl substances, the family of fluorochemicals historically used to give textiles durable water, oil and stain repellency. They are the subject of tightening restrictions in several markets and of stricter limits under certification schemes, which is why a repellent finish specified today may be a different chemistry from one specified a few years ago even where the performance requirement is unchanged. Read the guide on PFAS
pH
The acidity or alkalinity of an aqueous extract of the fabric, tested to check that dyeing and finishing chemicals have been properly washed off. Buyer specifications and import conformity schemes commonly require a near-neutral range, on the reasoning that residues well outside it can irritate skin in prolonged wear. Read the guide on pH
Pick glass
A small magnifier with a marked window, used to count ends and picks inside a measured square of fabric. It is the standard way to read an unknown cloth's construction from a sample or a worn garment.
Picks per inch
The number of weft yarns packed into an inch of finished fabric, written PPI on a spec sheet. Always read it on relaxed finished cloth, because a fabric measured under tension reports a lower figure than the one you receive. Read the guide on Picks per inch
Piece length
The length of cloth on a single roll, as against the total length of the order. A delivery of the right total metreage can still be hard to cut if it arrives as many short pieces, so the useful thing to fix in the order is a minimum acceptable piece length and a maximum share of the delivery that may arrive below it. Read the guide on Piece length
Piece-dyed
Fabric woven first and then dyed as finished cloth. Simpler and faster to reorder than yarn-dyed fabric, and the normal route for solid institutional shades. Read the guide on Piece-dyed
Pilling
Small balls of tangled fiber forming on a fabric surface under abrasion. Carded yarns pill more readily than combed, because the short fiber ends that cause it are still present. Read the guide on Pilling
Pilling grade
The 1 to 5 rating given after a pilling test such as Martindale or ISO 12945, where 5 is no visible pilling. Uniform specifications commonly set a minimum of 4, and the grade only means something with the test method and cycle count named beside it. Read the guide on Pilling grade
Plain weave
The simplest weave, each weft yarn passing over one warp yarn and under the next. Flat, stable and economical, with no diagonal line on the face. Read the guide on Plain weave
Ply
The number of single yarns twisted together to make the yarn actually woven. In a count written 2/18, the 2 is the ply and the 18 the count of each single, so a two-ply yarn is heavier and more even than a single of the same count. Read the guide on Ply
Poly-cotton
A blend of polyester and cotton. It trades some of cotton's breathability for polyester's strength, faster drying and lower shrinkage. Read the guide on Poly-cotton
Poly-viscose
A blend of polyester and viscose, the workhorse of Indian uniform suiting. Polyester brings durability and shape retention, viscose brings a softer handle and better drape. Read the guide on Poly-viscose
Polyester staple fibre (PSF)
Polyester produced as short cut lengths rather than as continuous filament, so it can be spun on cotton-system or blend spinning machinery. It is the polyester input in a poly-viscose or poly-cotton blended yarn, and its price tracks the PTA and MEG chain rather than the cotton market, which is why a blend can move in a direction cotton is not moving in. Read the guide on Polyester staple fibre (PSF)
Poplin
A plain weave with a fine warp and a slightly heavier weft, producing a smooth surface with a faint crosswise rib. It presses crisply, which is why it is a standard shirting for formal and corporate uniforms. Read the guide on Poplin
POY
Partially Oriented Yarn, the intermediate polyester filament yarn taken off the spinning line before it is fully drawn. It is not woven as it is; it is the feedstock that texturising converts into DTY.
Pre-dispatch inspection
Inspection of a finished lot before it leaves the mill, as opposed to inspection on arrival at the buyer's end. Some destination conformity schemes require it, and where they do it has to be arranged before the goods ship rather than after. Read the guide on Pre-dispatch inspection
Pre-export verification of conformity
A scheme under which imported goods are inspected or tested in the country of origin, before shipment, by a contractor appointed by the destination country's standards body. Kenya, Tanzania and Uganda run schemes of this shape. The defining feature is that it cannot usually be completed once the goods have sailed. Read the guide on Pre-export verification of conformity
Pre-production sample
The last sample cut before a full run starts, taken from the actual bulk lot and finished the same way, so the buyer can approve shade, handle and weight against the earlier approved standard. Once signed off it becomes the reference the bulk delivery is inspected against. Often shortened to PP sample. Read the guide on Pre-production sample
Pre-shrunk
Cloth whose residual shrinkage has been taken out at the finishing stage, by controlled compressive shrinking or heat setting, so that it changes little in the wearer's laundry. Pre-shrunk is a claim about a process, so ask for the residual shrinkage figure and test method rather than the word alone. Read the guide on Pre-shrunk
Preferential certificate of origin
A certificate of origin issued under a trade agreement, and the document an importer's customs needs before it will apply a concessional duty rate. What qualifies the goods is the product-specific rule in the agreement's origin annex; the certificate only evidences it. Read the guide on Preferential certificate of origin
Processing house
A unit that takes greige cloth from the weaver and carries out dyeing, finishing and testing before the fabric is despatched. Weaving and processing are often separate businesses, which is why a lead time has a loom stage and a processing stage. Read the guide on Processing house
Proforma invoice
A pre-invoice issued before goods ship, setting out quantity, specification, price, Incoterm, payment terms and delivery, so the buyer can open a letter of credit or arrange payment against it. It is not a demand for payment; it is the document the commercial terms are agreed on.
PTA
Purified terephthalic acid, one of the two feedstocks behind polyester. It is produced from paraxylene, traded internationally in dollars, and its price is a large part of why a polyester or poly-viscose quote moves without anything changing at the loom.
Puckering
A wavy or gathered surface that appears around stitching or after wash, caused by thread tension, dense stitch areas pulling a loosely set cloth, or differential shrinkage between cloth and thread. It reads as a fabric fault to the wearer and usually originates at the making stage. Read the guide on Puckering
Purchase order (PO)
The buyer's document that confirms an order against a quotation, fixing specification, quantity, price basis, delivery and payment terms. On custom shades the lead time counts from shade approval, not from the PO date, so the two dates should be planned separately. Read the guide on Purchase order (PO)
