    摘要： There are disclosed processes for preparing a textile treated with a water-insoluble polyester wherein a linear or branched chain water-soluble sulfonate or phosphate group containing polyester is coated or impregnated onto a textile substrate in combination with a crosslinking agent and subsequent to heating to co-react the crosslinking agent with the polyester, the treated textile substrate is exposed to an aqueous solution of a polyvalent metal ion reactive with said sulfonate or phosphate groups in said polyester. Alternatively, there are disclosed processes for preparing a water-insoluble polyester on a textile substrate wherein a branched chain polyester having sulfonate or phosphate groups is coated or impregnated onto a textile substrate, the substrate is dried and subsequently exposed to an aqueous solution of a polyvalent metal ion reactive with said sulfonate or phosphate groups in said polyester. The processes disclosed herein are useful in the preparation of nonwoven fabrics and finished woven fabrics such as sized fabrics including use as a pigment binder in sizing woven fabrics.

    摘要： Nonwoven fabrics and fabric laminates are formed from continuous filaments or staple fibers of a select blend of specific grades of polyethylene and polypropylene which give improved fabric performance not heretofore recognized or described, such as high abrasion resistance, good tensile properties, excellent softness and the like. Furthermore, these blends have excellent melt spinning and processing properties which permit efficiently producing nonwoven fabrics at high productivity levels. The polymers are present as a lower-melting dominant continuous phase and at least one higher-melting noncontinuous phase dispersed therein. The lower-melting continuous phase forms at least 70 percent by weight of the fiber and comprises a linear low density polyethylene polymer of a melt index of greater than 10 and a density of less than 0.945 g/cc. At least one higher-melting noncontinuous phase comprises a polypropylene polymer with melt flow rate of greater than 20 g/10 min.

    摘要： The invention is directed to composite nonwoven fabrics and processes for producing the same. The fabric includes a layer of inelastic continuous or staple fibers formed from a blend of polyethylene and polypropylene laminated to an extensible web, such as a polyolefin film. Preferably, the composition of the fibers ranges between 5 to 50 percent by weight of polypropylene with the balance made up of polyethylene. The nonelastic fibers are capable of being highly elongated upon mechanical stretching without adversely impacting fiber tie down. Accordingly, a smooth, strong, coherent fabric is obtained, which is especially well suited for incorporation into disposable absorbent articles such as diapers, training pants, incontinence briefs and feminine hygiene products.

    摘要： Lubricants and processing aids for thermoplastic synthetic fibers, particularly polyester and nylon fibers are disclosed together with processes therefor. Said lubricants comprise compounds having the structural formula: ##STR1## in which R and R.sub.1 are independently selected from straight or branched chain aliphatic radicals having about 7 to about 22 carbon atoms; A is oxyethylene or a heteric mixture of oxyethylene and oxypropylene residues derived from the reaction of ethylene oxide and 1,2-propylene oxide in the respective ratio by weight of about 3:7 to about 9:1; and n has a value to produce a compound having a molecular weight of about 300 to about 3000. Said compounds are the ethoxylated or alkoxylated reaction product of the reaction product of an alpha-olefin epoxide and a fatty alcohol.Where liquid products are desired which contain the higher numbered carbon chain residues, low viscosity compounds can be obtained by oxyalkylating the intermediate obtained by reacting an alpha-olefin epoxide with a fatty alcohol using an ethylene oxide and 1,2-propylene oxide mixture in the respective ratio as set forth above. By properly balancing the carbon chain length of the R and R.sub.1 groups in the lubricant compounds with the oxyethylene or oxyalkylene ratio, variation between insoluble and soluble products can be obtained.
