Cotton Wipers
White twill-patterned wiper, made of 100% long-staple cotton is tightly woven for strength and durability, while also clean and absorbent. Fabric is bias-cut and cross section of 120x60 threads per square inch. The woven twill pattern makes this wiper ideal for cleaning, polishing and burnishing magnetic disk media surfaces. Ideal in high heat applications, and absorbing aqueous and organic solvent spills. Suitable for Class 1000 and higher cleanrooms. Characteristics

Laundered Polyester Wipers
Polyester wipers with 100% continuous-filament in double-knit interlock textured, with a no-run circular pattern. Superb absorbency and construction, these wipers are cleanroom laundered and package for low particle and extractable levels.
Laundered wipers are ideal for critical environments where ultra-low particle/fiber generation and absorbent capacity is important. Soft yet durable construction cleans surfaces without scratching. The 2-ply wiper is commonly used in pharmaceutical applications as a primary process wiper.
Suitable for use in Class 1-Class 10 cleanrooms.
Lot quality controlled tested and traceable. Characteristics |

Nonwoven Pre-Saturated Wipers
These wipers are saturated with semiconductor grade (filtered to .2 micron) 70% isopropyl alcohol and 30% de-ionized 18 mega ohm water. Processed and package in a controlled environment, these highly absorbent and strong wiper are manufactured without the use binders, starches, or thermal bonding.
Smooth, soft texture wipe can be used on scratch sensitive surfaces. Designed for Class 10,000 applications and above. Low particle generation and leaves no residue on surfaces. Ideal wipe for electronics applications and for general use in pharmaceutical and semiconductor industries.
The economical choice for critical cleaning applications. All wipers are lot quality controlled tested and traceable. Characteristics |

Nonwoven Spun-lace Wipers
Coated & Non-coated Spunlace Wiper—White hydro-entangled, non-woven wiper is a 55% cellulose/45% polyester blend formed without bingers, starches, or thermal bonding techniques for a chemically pure sheet that is strong, clean and super absorbent. Very low particle generation and ultra-purity, yet high tensile strength and electrostatic dissipative. Characteristics
Commonly used where liquid retention is important. Great wipe for general applications in wipe down of area or product. Ideal for use in pharmaceutical and semiconductor applications. Suitable for Class 1000 and above environments.
Industrial Sontara 12”x13” Wiper—Blue hydro-entangled, non-woven wiper is a 55% cellulose/45% polyester blend formed without binders, starches, or thermal bonding techniques for a chemically pure sheet that is strong, clean and absorbent. The crepe finish material consists of a spunlace fabric manufactures thru hydraulic needling to form a strong, fabric like structure. Wiper is conveniently quarter-folded for ease of usage. Characteristics
3-Ply Wiper—Highly absorbent, hydro-entangles, non-woven cellulose thermally bonded between two outer layers of abrasion resistant, non-woven polypropylene. The polypropylene holds very little liquid, while wicking action passes spills into the cellulose layer. Wiper is extremely resistant to acids and is chemically pure with very low particle generation. This electrostatic dissipative wiper is excellent for wiping spills and cleaning surfaces.
