摘要： The invention disclosed a fabric made of cellulose acetate and/or cellulose triacetate, and optionally fibers of other selected substances, which are calendered at selected temperatures and pressures after having been water-wetted to a selected water content in order to bond the fibers of cellulose acetate and/or triacetate to one another and/or to fibers of the other selected substances. The selected calendering temperatures are from about 130°C to about 210 °C, preferably from about 160 °C to about 190 °C; the selected pressures are from about 500 to about 5000 psi, preferably from about 500 to about 2500 psi and most preferably from about 1000 to about 2500 psi; and selected water content is from about 20% to about 600% of fabric dry weight. The physical properties of the calendered fabric, for example the stiffness or hand resulting from different degrees of bonding can be changed by altering one or more of there parameters, either separately or in combination. The physical properties can also be changed by changed by changing the rate at which the fabric is passed between the calendering rollers or the type of rollers used, for example, smooth versus embossed or patterned rollers.
摘要翻译：本发明公开了一种由乙酸纤维素和/或三醋酸纤维素制成的织物，以及任选的其它所选物质的纤维，其在已经被水润湿至选定的水含量之后在选定的温度和压力下压延，以便将纤维素纤维乙酸酯和/或三乙酸酯彼此和/或其它所选物质的纤维。选择的压延温度为约130℃至约210℃，优选约160℃至约190℃; 所选择的压力为约500至约5000psi，优选约500至约2500psi，最优选约1000至约2500psi; 并且选择的水含量为织物干重的约20％至约600％。可以通过单独地或组合地改变一个或多个参数来改变压延织物的物理性质，例如由不同程度的结合产生的刚度或手。物理性能也可以通过改变在压光辊之间织物通过的速率或所使用的辊的类型，例如平滑与压花或图案化辊之间的变化而改变。
