A protective garment is constructed with a fibrous material. The fibrous material comprises a first nonwoven layer, a second nonwoven layer, and a nanofiber layer laminated between the first nonwoven layer and the second nonwoven layer. The fibrous material has a mean flow pore size greater than or equal to about 0.02 micron and less than or equal to about 0.5 microns, and a water vapor transmission rate greater than or equal to about 10000 g/m.sup.2/day and less than or equal to about 100000 g/m.sup.2/day. In a method of making a fibrous layer, a first nonwoven layer and a nanofiber layer are provided. A polyurethane reactive resin is applied to the first nonwoven layer in an amount of 2 to 30 g/m.sup.2. The nanofiber layer is then laminated to the first nonwoven layer applied with the polyurethane reactive resin and pressed to form the fibrous layer.

A method for manufacturing a printed wiring board which includes: Step (A) of laminating an adhesive sheet including a support and a resin composition layer bonded to the support to an inner layer board so that the resin composition layer is bonded to the inner layer board; Step (B) of thermally curing the resin composition layer to form an insulating layer; and Step (C) of removing the support, in this order, in which the support satisfies a condition (MD1): a maximum expansion coefficient E.sub.MD in an MD direction at 120° C. or more is less than 0.2% and a condition (TD1): a maximum expansion coefficient E.sub.TD in a TD direction at 120° C. or more is less than 0.2% below, when being heated under predetermined heating conditions, does not lower the yield even when the insulating layer is formed by thermally curing the resin composition layer with a support attached to the resin composition layer.

Textiles with improved surface stability

Resin dissolved or suspended in liquid is applied to a greige fabric formed with finer denier yarns forming surface loops before the fabric is bulked and after the liquid has been removed by low-temperature drying. The dried fabric is then bulked at a higher temperature setting the resin, resulting in superior loop tip resilience, and superior surface durability. Bulking and simultaneous resin setting optionally includes shrinking in area by 10-20%. Print appearance retention is also superior when printing follows bulking and setting of the resin.
