摘要:
A vertical bag-manufacturing and packaging machine includes a feeding unit having an upstream tube portion, an opening/closing mechanism, and a downstream tube portion. The upstream tube portion is configured and arranged to downwardly convey the article. The opening/closing mechanism is disposed on a downstream side of the upstream tube portion with a gap being formed between a downstream end of the upstream tube portion and an upstream end of the opening/closing mechanism, and configured and arranged to selectively open or close to selectively discharge or hold the article discharged by the upstream tube portion. The downstream tube portion is disposed on a downstream side of the opening/closing mechanism, and configured and arranged to downwardly convey the article discharged by the opening/closing mechanism, the downstream tube portion having an internal diameter that is larger than an internal diameter of the upstream tube portion.
摘要:
The present invention provides an agent for treating textile having a combination of a modifying agent and a fixing agent, wherein the modifying agent is a fluorine-containing phosphoric acid derivative represented by the formula wherein R.sup.1 and R.sup.2 are, same or different, a hydrogen atom or R.sub.f --(CH).sub.2).sub.m -- (wherein R.sub.f is a saturated or unsaturated, linear or branched fluorine containing aliphatic group having 4 to 20 carbon atoms in which an oxygen atom, a nitrogen atom, a sulfonyl group and/or an aromatic ring may intervene between the carbon atoms; and m is 1 or 2) (R.sup.1 and R.sup.2 each is not simultaneously a hydrogen atom), A is an oxygen atom, a sulfur atom or a direct bond, and n is 1 or 2, and having a molecular weight of not larger than 2,000 or a salt thereof, and the fixing agent is a metal salt compound; and a method for treating a textile by using the above agent for treating a textile and, if necessary, a fluorine-containing water- and oil-repellent or a fluorine-containing stainproofing agent. The present invention can maintain the touch, feeling, color shade and softness originally possessed by the fibers even if the textile is treated. The present invention can maintain the above properties even if the textile is subjected to a long term use including the washing and rubbing, and can impart hot water repellency and durable water- and oil-repellency.
摘要:
A textile treatment agent which contains, as an active component, a graft fluorocopolymer having a backbone of a polymer of a fluoromonomer and a branch of a polymer of a fluorine-free macromonomer prepared by copolymerizing the fluoromonomer with the macromonomer which is a fluorine-free macromonomer having addition-polymerizable unsaturated group at a molecular end gives excellent water- and oil-repellency and stainproof property.
摘要:
A stainproof treatment agent containing:(A) a fluoroalkyl group-containing copolymer having(I) a repeating unit derived from a monomer having a fluoroalkyl group,(II) a repeating unit derived from a monomer containing no fluorine,(III) a repeating unit derived from vinyl chloride, and(IV) a repeating unit derived from a crosslinking monomer; and(B) an acrylic copolymer containing no fluorine, has durability so that sufficient water- and oil-repellency as well as stainproof properties are maintained before and after cleaning.
摘要:
(1) A perfluoroalkyl diester of maleic acid or fumaric acid, (2) a copolymer obtained by polymerizing the perfluoroalkyl ester, a lower alkyl (meth)acrylate and, if necessary, styrene, and (3) a stainproofing agent comprising the copolymer give excellent water repellency, oil repellency and stainproof properties which have never been heretofore obtained.
