A pre-saturated wiper for use in a cleanroom environment, or other similarly controlled environment, that includes a woven fabric which incorporates a unique weave pattern with sealed edges that is saturated with only Ultrapure water (UPW).

An air spinning method comprising the steps of: preparing at least one web of textile fibers (N1), to be fed by at least one introducer element (24) upstream of an air spinning device (28), drawing said at least one web (N1) with at least one drawing device (32), feeding said web (N1), previously drawn, in a spinning chamber (36) of the air spinning device (28), spinning the fibers (12) inside the spinning chamber (36) by means of compressed air jets, so as to: obtaining a yarn (4) comprising internal fibers (20) surrounded by external fibers (16), wherein the yarn (4) has an overall thread count lower than Ne20 and wherein the total number of internal (20) and external (16) fibers is less than 200.

Disclosed is the preparation of improved high strength nylon staple fibers having a denier per filament of 1.0 to 3.0, a tenacity T at break of at least about 6.0, and a load-bearing capacity, T.sub.7, of greater than 3.2. Such nylon staple fibers are produced by preparing tows of relatively uniformly spun and quenched nylon filaments, drawing and annealing such tows via a two-stage drawing and annealing operation using relatively high draw ratios and then cutting or otherwise converting the drawn and annealed tows into the desired high strength nylon staple fibers. The nylon staple fibers so prepared can be blended with other fibers such as cotton staple fibers to produce nylon/cotton (NYCO) yarns which are also of desirably high strength.

The present invention relates to a method of manufacturing a high tenacity yarn and a high tenacity yarn manufactured thereby. More particularly, the present invention relates to: a method of manufacturing a high tenacity yarn, the method including coating a yarn made of at least one of nylon and polyester to obtain a coated yarn, wherein the coating material contains 3 to 35 parts by weight of a reinforcing agent composed of a mineral material per 100 parts by weight of a coating liquid containing polyurethane; and a high tenacity yarn manufactured thereby. Therefore, it is possible to manufacture a yarn having high tenacity and improved processability by processing a nylon or polyester yarn having a relatively low tenacity as compared with a high modulus polyethylene (HMPE) yarn by use of a yarn coating technique, and further to reduce production cost.

An improved unbonded loosefill insulation material having a multiplicity of tufts and a plurality of voids between the tufts is provided. The tufts have an average major tuft dimension. The average major tuft dimension of the tufts of the improved unbonded loosefill insulation material is shorter than an average major tuft dimension of tufts of conventional unbonded loosefill insulation material, thereby providing the improved unbonded loosefill insulation material with a higher insulative value than conventional unbonded loosefill insulation material.

Provided is a fiber containing a composition obtained by mixing a compound having at least a ring structure containing one carbodiimide group, the first nitrogen and second nitrogen thereof being linked together through a linking group, with a polymer compound having an acidic group. Also provided is a fiber structure made thereof. A fiber and a fiber structure, which have improved hydrolysis resistance and from which no free isocyanate compounds are produced, can be provided.

A process for texturing a multicomponent fiber is provided. The process comprises: (A) providing a multicomponent fiber having a shaped cross section and at least one water dispersible polymer; and a plurality of domains comprising one or more water non-dispersible polymers, wherein said domains are substantially isolated from each other by said water dispersible polymer intervening between said domains; and wherein the water dispersible polymer is present at the perimeter of the outside cross-section of the multicomponent fiber in a proportion of no greater than 55% water dispersible polymer; and (B) passing the multicomponent fiber through a first zone comprising a first heating device and a twisting unit, wherein the first heating device has a heating temperature that is at least 10% less than the temperature used for a fiber without the water dispersible component having the same water non-dispersible polymer, same number of total filaments in the fiber, and the same total denier for a given type of equipment and process conditions.
