    Abstract: PROBLEM TO BE SOLVED: To accurately detect a fluff by the end breakage of a monofilament for each traveling yarn in a process for efficiently producing a high-tenacity yarn of multifilament of four or more filaments at >=2,000 m/minute high spinning speed by direct spinning and drawing process. SOLUTION: This fluff detecting method comprises separating a fluff from a traveling yarn 2 composed of a multifilament by its centrifugal force when the direction of the traveling yarn is changed, hitting the fluff to a fluff detection tip part of a fluff detector 13 and detecting the fluff by its collision force. A fluff detecting device (b) having a fluff detecting tip part which is one fluff detecting tip part constituted of plural parts connected in the length direction so as to simultaneously and individually detect a fluff occurring in each traveling yarn of a multifilament of two or more filaments for each traveling yarn and in which each part has a mutually different wave shape of vibration is used. Information for each traveling yarn can be individually distinguished and detected by making the fluff detecting tip part of the fluff detecting device correspond to each traveling yarn.

    Abstract: PROBLEM TO BE SOLVED: To obtain both a polyester yarn for a canvas, having excellent stain resistance, retaining the excellent stain resistance for a long period of time, having high strength and high elasticity as a canvas, capable of controlling change in physical properties of yarn after heat setting of backing fabric and not causing yarn slippage of backing fabric of woven fabric and having excellent durability and a canvas using the yarn. SOLUTION: This polyester yarn for a canvas is obtained by using a polyester as a core part polymer and a polyester blended with a fluorine-containing polymer so as to have 0.05-5.0 wt.% fluorine content as a sheath part polymer. A sheath core conjugate yarn having 40-90 wt.% core part ratio and 10-60 wt.% sheath ratio is used at least in a part of a monofilament component. The polyester for a canvas comprises the core part having 0.90-1.10 intrinsic viscosity(IV), >=8.0 g/d strength,

    Abstract: PROBLEM TO BE SOLVED: To produce a pavement material enabling the improvement of abrasion resistance of concrete pavement by mixing and kneading thinned pieces of a recovery carpet into a mortar composition and at the same time to enable the effective recycling of the recovery carpet. SOLUTION: This pavement material is produced by mixing and kneading thinned pieces of a recovery carpet into a mortar composition consisting of cement, a small aggregate and water. The compounding ratio of the thinned pieces of the recovery carpet to the mortar composition is preferably in the area of carpet base material 1-side. Further, the thinned pieces are preferably prepared by cutting a carpet, consisting of a carpet base material 1 in which pile yarns 3 are planted in a tufting base cloth 2 and a filling layer 4 formed on the reverse side of the carpet base material 1, in roughly diagonal direction against the carpet obverse surface.

    Abstract: PURPOSE:To obtain the subject composite reinforced with fiber of high adhesivity, by treating e.g. raw cords consisting of a polyester and aromatic polyamide with each specific organic solvent-based adhesive and aqueous composition-contg. adhesive in succession followed by embedding the resultant cords in a rubber and curing. CONSTITUTION:Raw cords or fabrics therefrom consisting of a polyester and aromatic polyamide fibers is treated with an organic solvent solution of isocyanate compound as an adhesive and put to heat treatment followed by treating the resultant cords or fabrics with a second adhesive consisting of (A) an aqueous composition comprising a condensate formed by reaction between formaldehyde and resorcin in the molar ratio : 0.1/1-8/1 and a rubber latex in the weight ratio (on a solid basis): 1/1-1/1.5 and (B) a compound of formula I [X and Y is each Cl, Br, H, OH, alkyl, aryl, etc.; Z is of formula II (R3 and R4 are each H, alkyl, etc.;) etc.; n is 0, 1-15] in the weight ratio (on a solid basis) A/B=1/0.1-1/2. Thence, the resultant cords or fabrics are heat-treated followed by embedding the heat-treated cords or fabrics in a rubber and curing under a pressurized steam in an autoclave, thus obtaining the objective rubber composite.
