摘要： PROBLEM TO BE SOLVED: To provide polyester stretch yarn that can give refrigerant sense and swell feeling caused by its proper rigidity and dryness as well as has a reduced level of the soft and smooth feeling intrinsic to polyester itself. SOLUTION: This polyester textured stretch yarn has, in its single filament, a cross section of a trilobal Y shape with the modification degree of the cross section of 1.8-3.5, the stress at 100% elongation of 1.8-2.8 g/d and the crimp development of 5-30% of the crimped yarn.

Dry heat shrinkage factor [SHD(A)] of the component A =5% and SHD (B)-SHD(A)>=5.0% and crimp developing ratio (CC) of the component B >=30%, 2.0

摘要： PROBLEM TO BE SOLVED: To obtain an acetate-polyester combined filament confounding composite yarn producing textiles that have silky appearance, high stability and hygroscopicity, and do not give sticky touch by mix-spinning acetate filaments and specificpolyester-based multi-filaments, and confounding the combined filaments. SOLUTION: This acetate-polyester combined filament confounding composite yarn is obtained by mix-spinning and confounding acetate filaments and polyester multi-filaments which contain polyester filaments having smaller heat shrinkage than that of the acetate filaments. When this composite yarn is heat treated in condition of textile in such a process as dying, polyester filaments of low heat shrinkage covers textile surfaces, thus suppressing fibrillation and peeling.

摘要： PROBLEM TO BE SOLVED: To obtain a composite bound spun yarn affording soft touch feeling, excellent in handleability in its weaving/knitting process, and useful as e.g. a high-grade fashion material, by winding a part of short fibers onto a fiber bundle comprising specific polyester multifilaments.

It is preferable that the dry thermal shrinkage difference between the polyester multifilament group with the maximum dry heat shrinkage at 160 deg.C and that with the minimum dry heat shrinkage at 160 deg.C falls within a range of 5-60% and the weight ratio A/B is (20:80) to (70:30).

摘要： PURPOSE: To provide a bulky composite fasciated spun yarn having good handleability of weaving and knitting process and having both of proper swelling and soft touch feeling and provide a method for producing the spun yarn. CONSTITUTION: In this fasciated spun yarn winding a short fiber round a fiber bundle consisting mainly of a polyester multifilament and a short fiber, the polyester multifilament is composed of a polyester-multifilament A having negative heat shrinkage factor at 160 deg.C dry heat and a polyester multifilament B having >=5.0% heat shrinkage factor at 160 deg.C dry heat. This method for producing bulky composite fasciated spun yarn comprises heat-treating the polyester multifilament A to provide a characteristic having negative heat shrinkage factor at 160 deg.C dry heat, blending or doubling the polyester multifilament A with the polyester multifilament B without once winding, successively superposing the multifilament onto drafted short fiber bundle and introducing the fiber bundle into an air type false twist nozzle.

摘要： PURPOSE: To obtain a polyester woven or knitted fabric, having excellent water supplying performances, moderate soft touch feeling and bulkiness and further delicate dry touch and sufficient fullness and stiff feeling and useful for applications of women's wears. CONSTITUTION: This woven or knitted fabric is composed of a polyester multifilament composite yarn comprising two or more polyester multifilament yarns in which at least one is a self-stretchable polyester multifilament yarn having fine grooves extending in the direction at right angles to the fiber axial direction and excellent in water absorptivity. The fine grooves of the multifilament yarn having the fine grooves preferably have 1.5×d to 4.5×d μm maximum depth from the fiber surface to the deepest part and 1.5×d to 4.0×d μm width on the fiber surface [(d) is the single filament denier] and 3-10 number of the formed fine grooves for 10μm yarn length. The woven or knitted fabric is obtained by heat-treating an undrawn yarn melt spun at 2000-4000m/min spinning takeoff speed at 10-60% relaxing ratio under relaxed conditions, then compounding the heat-treated yarn with another drawn polyester yarn, twisting the composite yarn, weaving or knitting the resultant composite yarn and carrying out the weight reduction treatment of the obtained woven or knitted fabric by 5-35%.

摘要： PURPOSE: To obtain slub yarn which has a random and natural uneven thickness and suitable softness and can smoothly pass through the post-process by mixing and interlacing functional yarns including thermally elongating filaments and core yarns. CONSTITUTION: A polyester multifilament yarn of 100de/36f is guided, as a core yarn Y2 , through guides 2, 4 to the core yarn feed roller 5, while a functional yarn Y1 comprising polyester multifilament yarn of 30de/18f and a thermally elongating polyester filament yarn which elongates more than 2% with 160 deg.C dry heat in an amount of 30% based on the total denier is guided through guides 1, 3, to the feed roller 6 whose surface speed is varied with the invertor motor 7 controlled with the controller 8. Then, both yarns Y1 and Y2 are arranged in parallel and fed into the turbulent flow nozzle (device) to effect mixing and interlacing whereby slub yarn having 15-95% slub parts is obtained. In this slub yarn, the thickness of the slub part varies in the range of from 1.05 to 2.3 times, preferably from 1.1 to 2.0 times to the non-slub part and the maximum slab length is 0.1-30m, preferably 0.5-10m.

摘要： PURPOSE:To produce a polyester woven fabric exhibiting a high elasticity even under a strong restraint condition or in the case a twisted crimped yarn is used. CONSTITUTION:The characteristic of this method for production of an elastic polyester fabric is that it is carried out by applying a hydrolysis treatment to a composite fiber composed of polyester-based multifilament crimped yarns (A) and readily soluble polyester-based multifilament yarns (B) having a yarn length 0 to 15% shorter than that of (A) and a hydrolysis rate >=10 times higher than that of (A) and satisfying twist coefficient K=40 to 200 and number of twist=100K/sq. rt. D (provided that D is the denier number of the composite fiber) or a fabric woven by at least partly using it, removing the readily soluble polyester-based multifilament yarns (B) and subsequently applying a relaxation treatment thereto.
