Novel universal ink jet recording medium

InactiveUS20020182376A1Avoid curlSmooth and high gloss surfaceDuplicating/marking methodsCoatingsCellulosePolyvinyl alcohol
The described invention is an unique universal ink jet media. The invention incorporates a unique barrier layer based upon UV or EB curable chemistry which replaces common polyethylene extruded bases. The invention also incorporates multiple ink receptive layers. The first layer is based upon gelatin and / or polyvinyl alcohol (PVOH) chemistries and gives the invention excellent ink drytime. Poor drytime is a common problem which leads to smudging and print defects, especially as ink jet printer speeds increase as technology improves. The high ink absorbency of the invention also makes this media well suited for wide format ink jet printers. The next ink receptive layer(s) are based upon pigmented, cellulose chemistry which reduces the tack of the sheet and gives the sheet good waterfastness. This is important for the end use in that the sheet may be frequently handled and exposed to dampness. Another unique property provided by the next ink receptive layer(s) is excellent print quality across a wide range of printers and ink sets (both dye and pigmented), in which other media perform poorly. A final unique property is an anti-curl coating which resists curling as the ambient conditions change from cold and dry to hot and humid.

Tape dispenser having a tape retaining and application area

A tape dispenser having a frame, a cutter blade and at least one pair of projections disposed on the opposed interior surfaces of the side walls is disclosed. The distance between the projections is less than the distance between the interior surfaces of the side walls and is also less than the width of the tape held in the dispenser. The tape dispenser may also include a pair of tabs either associated with the projections or positioned between the projections and the tape mount. The dispenser is adapted to hold a roll of adhesive tape therein and because of the decreased distance between the projections, the tape assumes a convex shape when viewed from the front end of the dispenser. The shape of the tape and position of the tabs and projections causes the tape to be biased into contact with the interior of the front end of the dispenser. This helps to keep the free end of the tape out of contact with the roll in the dispenser.

The invention provides a high-elastic denim fabric, wherein PTT fiber filaments and spandex filaments are adopted as core yarns. Fasciated yarns are spun into double stretch yarn core-spun yarns, and then the double stretch yarn core-spun yarns are weaved in a three-upward one-downward right twill-weave mode to form cotton roves. After that, the high-elastic denim fabric is prepared successively through the steps of spinning double stretch yarn core-spun yarns, warping, starch dyeing, singeing, desizing, mercerising and washing finished products. The tensile elastic elongation rate of the high-elastic denim fabric prepared by the above method is up to 53.5% and the tensile elastic recovery rate thereof is up to 92.7%. Meanwhile, through setting the ratio of two types of stretch yarns, stretch yarns of different elastic performances can be obtained to meet different elastic requirements. The current situation that the conventional male denim fabric is not elastic can be changed. Meanwhile, the physical and chemical properties and the wearing comfortness of male denim clothes are improved to a certain degree. The fabric is soft and comfortable in hand feeling, good in shape-retaining ability, high in degree of dyeing and good in color fastness, thereby meeting the moderate sport requirement of men when wearing denim clothes. At the same time, the fabric does not unduly fit, thus having a good development prospect and a large value space.
