Thermoplastic materials are converted directly into thermally bonded, coherent fibrous products by melt blowing techniques. The fibrous product is in the form of a rod having a relatively dense, rigid skin in which the fiber portions are oriented primarily in a longitudinal direction with respect to the axis of the product, and a less dense core where the fiber portions are oriented primarily in a transverse direction with respect to the axis of the product. The products are made by melt blowing fibers and intercepting them by a fiber collecting and forming device which permits a relatively heavy build-up of fiber mass in the central portion and a relatively light build-up of fibers in a lip portion surrounding the central portion. As fibers are continuously deposited on the collecting and forming device, the product thus formed is withdrawn at a rate synchronized with collection of fibers such that the aforesaid build-up is maintained, and such that the lip portion is folded back over the central portion by the collecting and forming device to form the rod as described.

This invention concerns fibers of amorphous polyesters of terephthalic acid or an ester forming derivative thereof and from about 60 mole percent to 100 mole percent 1,2-propylene glycol and from 0 to about 40 mole percent ethylene glycol. These fibers are useful for the production of bonded coherent cigarette filters, nonwoven fabrics and the like.

Water and glycol bonding dispersion comprising water, high boiling glycols selected from 1,2-propanediol, 1,3-propanediol, 1,4-butanediol, 1,2-butanediol and 1,3-butanediol; and water and glycol dispersible polyester polymers. The polymer is present in the amount of about 5 to 40% by weight of the dispersion and preferably about 15 to 35% by weight, and is selected from polyesters of combinations of isophthalic acid and the sodium, potassium, or lithium salt of sulfoisophthalic acid reacted with diethylene glycol or triethylene glycol; and from terephthalic acid and the sodium, potassium or lithium salt of sulfoisophthalic acid reacted with diethylene glycol or triethylene glycol. The water and selected glycol(s) serve as a carrier or dispersion medium for the selected water and glycol dispersible polymer. The dispersions contain from about 0. 1-20% water by weight.

A process is disclosed for treating cellulose ester articles which comprises applying to the surface of the articles a solution of alkylated melamine such as hexamethoxymethylmelamine and an acid catalyst. The solution is applied such as to result in a deposit of alkylated melamine in an amount of between about 1% and about 10% based on the weight of the cellulose ester article and acid in an amount of from about 0. 01 to about 1. 0% based on the weight of the cellulose ester article. The article is then heated to cause a reaction to occur between the alkylated melamine and the surface of the cellulose ester article to form a crosslinked skin to render the article resistant to attack by solvents.

This invention relates to a method for rendering a surface substantially impervious to alpha particle radiation such as that produced through radon decay. More particularly, the present invention involves applying to said surface an emulsion containing a sulfopolyester and a copolymer of vinyl acetate and dialkyl maleate, and a plasticizer. The sulfopolyester-acrylic copolymer blend produces a stable alpha particle radiation barrier on sand, rocks and soil.
