The present invention includes novel barrier webs that have certain desirable physical qualities such as water resistance, increased durability, improved barrier qualities and the like. The present invention further comprises a barrier web comprising a web that has been treated with a curable shear thinned thixotropic polymer composition, the fabric being adapted to be substantially impermeable to liquids, permeable to gases and impermeable to microorganisms. The barrier webs of the present invention are either impermeable to all microorganisms or are impermeable to microorganisms of certain sizes. The present invention also includes fabrics that are capable of either selective binding certain microorganisms, particles or molecules depending upon what binding partners are incorporated into the polymer before application to the fabric.

摘要:
The present invention provides an ultrahigh molecular weight polyolefin fiber coated with a coating composition, wherein the coating composition contains a UV stabilizer, characterized in that the amount of UV stabilizer is between 2 wt% and 80 wt.% compared to the total weight of the coating composition based on solids. The UV absorber can be selected from the group consisting of hydroxybenzophenones, hydroxyphenylbenzotriazoles, oxalanilides, phenyl esters, benzooxazinones, cyanoacrylates, formamidine, benzylidene malonates and hydroxyphenyl triazines and combinations thereof. Such fibers are particularly useful in ropes and fishing nets.

The compositions further contain a polyurethane containing blocked isocyanate groups. They are useful for treating fiber materials, especially textile sheet materials, and can be applied thereto in the form of aqueous solutions or dispersions. Textiles which are 50 to 100 % by weight wool and have been finished with the compositions exhibit low shrinkage and low felting tendency during washing operations and also a pleasant, soft hand.

摘要:
The present invention relates to methods and apparatus for the controlled placement of a shear-thinnable polymer composition into a moving web. The controlled placement is preferably performed by applying the polymer composition onto a surface of a moving web, shear-thinning the composition and placing it into the web, and curing the polymer composition. A preferred apparatus includes one or more process heads (310) that has mounted thereto a rigid knife blade (311) for engagement with the moving web (302). The knife blade (311) is movable vertically and rotationally. The process heads (310) are also movable horizontally along the path of the moving web (302). A plurality of macro and micro tension zones (5, 6, 7, 8, 9, 10 and 11) are established and are monitored for controlling the apparatus and process. Additional measurements of web density, micro porosity, placement of an internal layer of polymer within the web, analysis of elements on the treated web, and the size of the polymer bead applied to the moving web are measured for controlling online the apparatus and the process of this invention. This method and apparatus produces webs that either has some of its structural elements encapsulated by the polymer composition while at least some of the interstitial spaces of the web are open; or has an internal layer extending through the web in a direction generally spaced from at least one major surface thereof; or has both encapsulated structural elements and an internal layer of polymer composition.
