Abstract:
Processes and apparatus for dyeing a textile product are provided whereby an undyed textile product is introduced into a substantially anaerobic dyeing chamber having an oxygen content of less than 1000 ppm oxygen therein, and at least two dye mixtures having a differential dye exhaustion rate of at least 10% are applied onto the textile product within the substantially anaerobic dying chamber. Thereafter the dyed textile product may be exposed to an oxygen-containing atmosphere so as to oxidize the applied dyes. At least one of the dyes may have a dye exhaustion rate of at least about 25%, or even at least about 50%. The embodiments herein are especially adapted to dyeing of textile products whereby one dye in the at least two dye mixtures is a sulfur dye and another dye in the at least two dye mixtures is a leuco indigo dye.

Abstract:
Provided is an artificial leather that achieves both a soft texture and excellent durability, and a method for manufacturing the same, the leather comprising: a fibrous base material formed from superfine fibers having an average single fiber diameter of 0.1-10 μm; and a polymeric elastic body, where the polymer elastic body comprises a compound having a hydrophilic group and a compound having an ethylene oxide skeleton, the content of the compound in the polymeric elastic body of the artificial leather being 0.1-5 parts by mass per 100 parts by mass of the polymeric elastic body.
Abstract:
A sorptive wiper for cleaning is disclosed, the wipe comprising a cleaned and dried sorptive material having fewer than 150 contaminant fibers per square meter that are greater than 100 μm in length.
Abstract:
A process for treating a substrate comprised of sorptive material is provided herein. The sorptive material may be an absorbent synthetic material such as polyester. The material is designed to be used for cleaning surfaces in an ultraclean environment. The process first comprises unwinding a roll of sorptive material as a substrate into a cleaning system. The cleaning system utilizes several sections. These include a pre-washing section, an acoustic energy washing section, and a drying section. Preferably, the process of moving the substrate through the cleaning system is continuous. The acoustic energy washing section employs one or more acoustic energy generators. In one aspect, the process also includes cutting the substrate into sections to form wipers after moving the substrate through the drying section. Thereafter, the wipers are placed into a bag and the bag is sealed.
Abstract:
The present invention relates to a process for the production of coated textiles in which a textile substrate is firstly brought into contact with an aqueous dispersion comprising at least one inorganic salt and at least one modified cellulose.
Abstract:
Disclosed is a reusable incontinence products treated with a polyethylene glycol formulation in the form of a pad that is worn by a user for the control and collection of bodily fluids. The pad may include two or more layers, wherein one layer absorbs the bodily fluid and the other layer acts as a barrier layer to prevent the fluid from soiling a user's garments. Further embodiments are disclosed including a folder for conveniently carrying a supply of fresh pads and a waterproof pocket to contain soiled pads, and a pant for holding the pads in place next to the skin.
Abstract:
A synthetic-rich fabric (e.g., polyester, polypropylene, nylon, acrylic and elastane fibers—including lycra, spandex, etc.) useful in the manufacture of commercially launderable items is described. The fabric has many of the properties that make cotton fabrics desirable including hand feel, and wicking, but retains the best properties of synthetic fabrics, m addition, the soil release properties, pilling resistance and UV protection offered by the present items makes the fabric ideal in manufacturing apparel and non-apparel (e.g., pillow cases, bed sheets, aprons, tablecloths, napkins, etc.) items.
Abstract:
The cleansing polyester fabric of the present invention (AAA). The cleansing fabric of the present invention is useful as a makeup cleansing fabric or as a wiping fabric for precision products and optical devices since it exhibits excellent cleansing performance, is soft to the touch and does not damage the surface of a products to be cleansed.
Abstract:
The present invention relates to a nonwoven fabric having a relatively low level of ionic contaminates which is achieved by exposing the fabric to a deionized water wash, preferably, in-line with the nonwoven production process, thereby eliminating, or at least reducing, the need for an expensive and time consuming cleanroom laundering. The fabric is primarily comprised of continuous filament fibers and may be manufactured into such end-use products as cleaning wipes and protective clothing for cleanrooms and surface coating operations, such as automotive paintrooms. Also encompassed within this invention is a method for producing a nonwoven fabric having a relatively low level of ionic contaminates.
