  • Publication number: 20210120890
    Abstract: A garment, to which a blower device is detachably attachable, includes a main body and a heat insulation material. The main body includes at least an outer fabric having an attachment hole through which the blower device can be partially inserted. The main body is configured to cover at least a portion of a body of a wearer. The heat insulation material is attached to the main body at least on an inner side of the outer fabric. The heat insulation material is configured to cover at least a portion of the body. The garment is configured such that the heat insulation material is detachable from the main body.

  • Publication number: 20200359715
    Abstract: A garment includes a blower device having an inlet and an outlet, an outer fabric, and an inner fabric attached to the outer fabric. The outer fabric has a mounting part to which the blower device is removably mountable in a state in which the inlet is disposed on an outer side of the outer fabric and the outlet is disposed on the inner fabric side of the outer fabric. The internal space is formed between the outer fabric and the inner fabric. The internal space is configured such that, when the garment is not worn and the blower device delivers the ambient air into the internal space at an air volume Q (cubic meter per minute: m3/min), the air volume Q and an internal pressure P (pascal: Pa) of the internal space satisfy a relationship of P?1.1Q2.

  • Publication number: 20090022989
    Abstract: High-quality differential-shrinkage polyester combined filament yarn having good color tone and being free from fluffing can be made from a polyester polymer produced by using a catalyst comprising (I) a mixture consisting of a Ti compound component composed of one or more members selected from among titanium alkoxides of the general formula (I) and products of reaction of these alkoxides with carboxylic acids of the general formula (II) or anhydrides thereof and a P compound component consisting of a compound of the general formula (III) and/or (2) a product obtained by reacting a Ti compound component composed of one or more members selected from among titanium alkoxides of the general formula (I) and products of reaction of these alkoxides with carboxylic acids of the general formula (II) or anhydrides thereof with a P compound component consisting of a compound of the general formula (IV).

  • Publication number: 20060210797
    Abstract: Polyester fibers having a deformed section are produced from a polyester polymer which is obtained by polycondensing an aromatic dicarboxylate ester in the presence of a catalyst containing a mixture of a Ti component (A) comprising at least one a titanium alkoxide or a reaction product thereof with a specific carboxylic acid or its anhydride with a P compound component (B) represented by the following general formula (III) and/or a reaction product of a Ti compound component (C) with a P compound component (D) represented by the following general formula (IV). The obtained fibers have a favorable color tone and excellent qualities without showing fluffing.

  • Publication number: 20040175542
    Abstract: A fabric having worsted yarn fabric-like hand and appearance and a satisfactory stretchability, is obtained by melt-spinning two types of polyesters, different in intrinsic viscosity from each other, to produce a conjugate multifilament yarn; winding-up the yarn at a speed of 1,000 to 4,500 m/min; unwinding the wound yarn; unevenly drawing the yarn at a draw ratio lower than a natural draw ratio thereof to produce a thick-and-thin yarn; forming a fabric from the yarn; and applying a mass reduction treatment with an alkali to the fabric with a mass reduction of 3 to 30 mass %, to cause a plurality of cracks extending in a direction crossing the filament axis to be formed on the peripheries of individual filaments of the yarn.

  • Patent number: 6620504
    Abstract: A thick and thin polyester multifilament yarn having an excellent natural fiber yarn-like hand, a dry touch and spun yarn-like appearance includes a plurality of individual thick and thin polyester multifilaments varying in thickness along the longitudinal direction thereof and exhibits a spectrum having a first peak (Pmax1) of a coefficient of variation in yarn thickness of 4 to 10 cm, a second peak (Pmax2) of the yarn thickness variation coefficient of 50 to 150 cm and a ratio (Pmax1/Pmax2) of 1.5 to 4.0, measured by the normal mode test method using the Uster evenness tester.
