    • Alkylamine polyether surface active agent compositions and methods for using are described. The instant compositions are low foaming, and pH sensitive and are generally of the structure: ##STR1## in which (a) R.sub.1 may be hydrogen or alkyl;if R.sub.1 is hydrogen then R.sub.2, R.sub.3 and R.sub.4 must be alkyl having a total number of carbon atoms falling in the range of 7 to 23;if R.sub.1 is alkyl, then R.sub.2, R.sub.3 and R.sub.4 may be alkyl or hydrogen, the total number of carbon atoms in R.sub.1 +R.sub.2 +R.sub.3 +R.sub.4 falling in the range of 7 to 36 (preferably about 10 to 20);(b) The --(C.sub.2 H.sub.4 O).sub.m -- segment must be a poly(oxyethylene) homogeneous chain or "block" polymer (i.e., a homopolymer), m having an average value in the range of 1 to 15, preferably 5 to 13; and(c) Y is selected from the group consisting of:(1) homogeneous poly(oxypropylene) chain (PO) "block" polymer or residue (i.e., a homopolymer), of the structure --(C.sub.3 H.sub.6 O).sub.n H, n having a value in the range of 1 to 50, preferably 6 to 30;(2) hydrophobic end cap (e.g., --CH.sub.2 --.phi.); and(3) hydrophobic end capped polyoxypropylene residue.A particularly preferred class of surfactants of the instant invention constitutes 1,1,1-trialkylmethylamine ethyleneoxy(EO)-propyleneoxy(PO) polyethers having from 1 to 15 moles of ethyleneoxide residue and from 1 to 50 moles of propyleneoxide per mole of alkylmethylamine.The methods of the instant invention generally relate to the production of paper from secondary fiber. Unexpectedly, the compositions of the instant invention are found to be applicable in the common methods employed very pH sensitive, size-safe and to produce paper products from secondary fiber.

    • Paper webs are produced in a modified conventional felted wet press process in which the fiber furnish has a chemical debonding agent added thereto in high concentrations. The web (17) is formed on a conventional Fourdrinier wire (12), transferred to a moving felt (19) which presses the web against the surface of a drying cylinder (23) to reduce its water content, and is carried by the surface of the drying cylinder (23) to a creping blade (24). Liquid adhesive is applied to the surface of the creping cylinder (23) adhead of the contact with the web to provide substantial adherence of the web to the creping surface at the point of contact with the creping blade. The levels of addition of debonding agent to the pulp furnish and the amount of adhesive applied to the creping surface are selected such that the adhesion of the web to the surface at the creping blade is greater than the internal cohesion of the web. Under these conditions, a highly bulked and internally delaminated web is produced which has bulk and absorbency superior to products ordinarily produced in the conventional wet press process. The bulk and absorbency of the finished web may be further enhanced by utilizing a reverse angle creping blade (24) which meets the surface of the creping cylinder (23) at a cutting angle not more than 72.degree. and preferably between 52.degree. and 64.degree.. The reverse angle blade causes the fibers in the web to reverse direction at the line of contact with the creping blade and therefore enhances the disruption of fiber bonds to increase bulkiness.
    • 纸幅以改进的传统的压制湿压制法生产,其中纤维配料以高浓度加入其中的化学脱粘剂。 腹板(17)形成在传统的长网线(12)上,转移到移动的毡(19)上,移动的毡(19)将幅材压靠在干燥筒(23)的表面上以减少其含水量,并由表面 的干燥筒(23)连接到起皱刀片(24)。 将液体粘合剂施加到与网状物接触的顶部的起皱圆筒(23)的表面上,以在与起皱刀片接触的点处提供幅材到起皱表面的实质粘附。 选择向纸浆配料中添加脱粘剂的水平和施加到起皱表面上的粘合剂的量,使得幅材在起皱刀片处的表面的粘附力大于幅材的内部内聚力。 在这些条件下,产生了高度膨胀和内部分层的网,其具有优于常规湿式压制方法中通常生产的产品的体积和吸收性。 通过利用在不大于72°,优选在52°和64°之间的切割角度处与起皱圆筒(23)的表面相遇的反角起皱刀片(24),可以进一步提高成品纤维网的体积和吸收能力。 。 反角刀片使得纤维网中的纤维在与起皱刀片接触的线处反向,因此增加纤维粘结剂的破坏以增加蓬松度。

    • Synthetic sheet material is resistant to decay by fungus and other microbial organisms and particularly useful in shoe construction where flexibility is required. The material comprises a uniform distribution of cellulose and optionally synthetic fiber within an acrylic elastomeric matrix or binder and is formed from a furnish of the fibers; a metallic quinolinolate which lends the material decay resistant; a polymer colloid such as an acrylic latex which prevents the coagulation of the subsequently added acrylic elastomeric binder by the metallic quinolinolate; and a cationic polymer which acts as a retaining agent for the metallic quinolinolate in the synthetic sheet material.
