摘要： Disclosed is a process for continuous perforation of fabrics that comprise thermoplastic fibers. The process utilizes a combination of heat and pressure to perforate fabrics where the shape. size, and distribution of the individual fabric perforations is define solely by the design of the pattern embossing roll, In particular, the top side of the individual embossing points are not flat but rather have a raised peripheral edge so that the actual fabric contact area of the bond points is much less than total area circumscribed by each bond point. The small ratio of fabric contact area to total bond area concentrates the thermal and compressive forces in the embossing nip and allows a large perforation to be cut out of a fabric moving at high speed through the perforation nip.

摘要： A nonwoven web is provided which can be readily converted to an apertured web by stretching. In its initial non-apertured state, the web comprises a plurality of multicomponent fibers comprising at least two thermoplastic polymer components arranged in at least first and second separate continuous structured domains. The polymer component of the first domain comprises polyethylene. Prior to stretch aperturing, the web has a peak elongation of at least 100 percent and is characterized by having a plurality of discrete, spaced-apart, frangible bond sites of polymer bonding the fibers to form a coherent extensible nonwoven web. The frangible bond sites are structured and arranged to readily rupture when subjected to tensile stress to form discrete, spaced-apart apertures in the nonwoven fabric. The web has a total energy absorption in at least one of the machine direction or the cross-machine direction of at least 50 gcm/cm2.

摘要： The invention is directed to composite elastic 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 elastic layer. 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 synthetic fibers, particularly polyester and nylon fibers, are disclosed comprising compounds having the structural formulas: ##STR1## in which R is an aliphatic group generally having about 3 to about 22 carbon atoms; A is a mixture of residues from ethylene oxide and at least one other lower alkylene oxide, preferably a heteric mixture of oxyethylene and oxypropylene residues in the respective ratio by weight of 20:80 to 90:10; and n has a value to produce a molecular weight of about 300 to about 3000.Where liquid products are desired which contain the higher numbered carbon chain residues, low viscosity compounds can be obtained by oxyalkylating a glycerol-1,3-dialkylether with a mixture of ethylene oxide and 1,2-propylene oxide in the respective ratio as set forth above. Thus it is possible by properly balancing the carbon chain length of the R groups in the lubricant compounds of the invention with the oxyalkylene chain length to obtain products varying between water insoluble and water soluble. The oxyalkylated fiber lubricants of the invention have the properties of viscous liquids, solids or pastes at ambient temperature.

摘要： The present invention provides new linear phosphorus- and halogen-containing flame retardant polyester additives for normally flammable polymers and coatings for normally flammable natural and synthetic films and fibers, for instance, polyester and cellulose ester films and fibers. The phosphorus- and halogen-containing polymers of the invention are water dispersible or can be rendered water-soluble. They can be prepared by reacting a phosphorus acid reactant such as phosphoric acid with at least one halogenated difunctional monomer. The water-soluble polyesters can be cross-linked to render them insoluble in water by heating together with a methylol compound.Said halogenated monomer is preferably an oxyalkylated diacid or diol and said halogen is attached either on one or more aromatic rings or on a cycloaliphatic ring. The halogenated diols useful in preparing the flame-retardant polymer additives of the invention are selected from the group consisting of at least one of the halogenated, saturated diols having the formula: ##STR1## wherein m and p are integers of 2 to 6; n and q in formulas A, C, and D are 0 or integers of 1 to 10 and integers of 1-10 in formula B; wherein in formulas A-C, X which is attached to an aromatic ring represents 1 to 4 halogen atoms; and wherein in formula D, X represents 1 to 2 halogen atoms and Z is hydrogen, a C.sub.1 -C.sub.6 alkyl radical, or phenyl.Polymer fibers and films such as those made from polyethylene terephthalate and cellulose ester fibers and films such as those prepared from cellulose acetate and cellulose triacetate, each containing a flame-retardant amount of the phosphorus- and halogen-containing flame-retardant polymer additives of the invention are resistant to loss of the polymeric flame-retardant additives of the invention during use.

摘要： Flame-retardant antistatic polymer additives are provided which inhibit the buildup of electrostatic charges upon the addition of such compositions to synthetic polymeric fibers, i.e., polyamide fibers, and at the same time do not contribute to the flammability characteristics of such polymeric fibers. The flame-retardant antistatic polymer compositions are useful in combinations with fibers such as polyamide, polyester, polyurea, polyurethane, polysulfonamide, polyolefin and polyacrylic fibers. The antistatic effect is obtained by the process of coating the fibers or dispersing in or on the fibers up to about 12 percent by weight of a polymer composition which is the reaction product of:(a) a polyoxyalkylene compound or polyester thereof and(b) at least one reactant selected from the group consisting of (1) a diol, (2) a polyester and (3) an aliphatic or aromatic diacid or derivative of (3), wherein at least one said reactant is halogenated.Improved flame-retardant properties can be obtained by including with the flame-retardant, antistatic polymer composition an effective flame retardant proportion of a compound containing a metal from group Vb of the periodic table. Generally about 1:4 to about 4:1 parts halogen to antimony compound is used. Such compounds are oxides of metals such as phosphorus, arsenic, antimony, or bismuth with the preferred compound being antimony trioxide.
