    Abstract: A sizing composition for textile glass fibers comprising a starch, a textile softener, a lubricant and 100 to 150 percent by weight of combined nonionic wetting agents based upon the weight of said lubricant. The glass fibers sized in accordance with this sizing composition has found utility in forming untwisted yarns which are to be subsequently used for the weft of a textile glass fabric.

    Abstract: The specification describes a process for making a sheet molding compound wherein a layer of resin-filler paste that includes a thickening agent and a hardening catalyst is put down upon a first layer of sheet material; a layer of glass fibers that are sized with a material which induces wet out is placed thereon; following which another layer of the resin-filler paste containing the catalyst is placed thereon and covered by a second layer of sheet material. The sandwich thus formed is fed into the bite of rollers which squeeze out air and compress the resinfiller paste around the sized fibers, following which the composite is placed under further compaction that includes a perforating means which forces needle-like members through at least one layer of the sheet material, through the resin-filled paste, and into the layer of fibers for the removal of remaining entrapped air. The glass fibers which are used are sized with a material that includes both a hardening resin, and a nonhardening resin. Specifically, the fibers are coated with an unsaturated polyester resin and a saturated polyester resin which are preferably deposited on the glass fibers as emulsified particles.

    Abstract translation: 该说明书描述了一种制备片状模塑料的方法，其中将包含增稠剂和硬化催化剂的树脂填料膏层放在第一层片材上; 一层玻璃纤维的尺寸与诱导湿润的材料一起放置在其上; 随后将含有催化剂的另一层树脂填料糊剂放置在其上并被第二层片材覆盖。 将如此形成的夹层送入滚筒的咬合中，挤出空气并将树脂填充剂浆料围绕尺寸的纤维压缩，随后将复合材料置于进一步的压实下，其包括穿刺装置，其迫使针状构件至少 一层片材，通过树脂填充的糊料，并进入纤维层，以除去残留的夹带空气。 使用的玻璃纤维的尺寸为包括硬化树脂和非硬化树脂两者的材料。 具体地说，纤维被涂覆有不饱和聚酯树脂和饱和聚酯树脂，其优选沉积在玻璃纤维上作为乳化颗粒。
