The pretreatment liquid of the present invention is applicable for a fabric to be used for inkjet textile printing, and the pretreatment liquid contains a block copolymer including a hydrophobic block derived from a hydrophobic resin having an SP value of less than 11 and a hydrophilic block derived from a hydrophilic resin having an SP value of 11 or more, with the difference between the SP values of the hydrophobic resin and the hydrophilic resin of 1.0 or more; and water.

The present disclosure is directed to insect-resistant fabrics or garments and methods for making the same. The insect-resistant fabrics or garments include an insect repelling composition containing a micellar system and optionally an insecticide composition. As an example, an insect-resistant fabric in accordance with the disclosure can include a base fabric (e.g., polyester) having been treated to include an insect repellant composition containing a micellar system. The micellar system may include one or more insect repelling agents (e.g., essential oils) contained within one or more micelles (e.g., saponins) in a first region of the fabric, and optionally an insecticide (e.g., permethrin) in second region of the base fabric. The inclusion of a micellar system in an insect repellant composition is shown herein to provide improved insect-resistant efficacy. Additionally, certain insect-resistant fabrics disclosed herein can also demonstrate durability when exposed to wear such as laundering the garment.

[Problem] To provide a sizing-agent-coated carbon fiber bundle in which, even when the sizing-agent-coated carbon fiber bundle has superior handling properties, the sizing agent on the sizing-agent-coated carbon fiber bundle exhibits excellent solubility in water and the adhesion amount of remaining sizing agent is reduced. [Solution] A sizing-agent-coated carbon fiber bundle obtained by applying polyethylene glycol and/or a surfactant to a carbon fiber bundle as a sizing agent, wherein all of the following conditions (i)-(iii) are satisfied. (i) The adhesion amount of the sizing agent is 0.15-0.80 parts by mass (inclusive) per 100 mass parts of the sizing-agent-coated carbon fiber bundle 100. (ii) The dry F-F friction coefficient is 0.39 or less. (iii) The adhesion amount of the sizing agent after washing for 50 seconds under the conditions disclosed in the specification is 0.12 parts by mass or less per 100 parts by mass of the sizing-agent-coated carbon fiber bundle 100.

The present application relates to a sizing agent composition, a carbon fiber material and a composite material. The sizing agent composition includes a first composition solution and a second composition solution, and those solutions respectively has specific compound. The sizing agent comprising the composition has an excellent bonding property with a carbon fiber, and further the sizing agent can efficiently enhance heat resistance, wear resistance and processability of the carbon fiber material. The carbon fiber material sized with the sizing agent has a high adhesion property with specific resin material, therefore producing the composite material with high processability.

Provided is a knit fabric which does not cause feelings of clamminess, feels very cool to the touch and is comfortable, and limits feelings of stickiness and post-sweat chill through rapid drying of sweat, and at the same time is capable of further improving texture. The garment comprises a multilayer-structure circular-knit fabric made of a single circular knit with a layered structure of at least two layers, and the surface that contacts the skin is the needle-loop side of the circular-knit fabric. The circular-knit fabric has portions in which long cellulose fibers and hydrophobic fibers are knit together to form the same knit loops. The garment contains 10-50 weight % of the long cellulose fibers. The exposure rate of the long cellulose fibers in the region from the surface of the side that contacts the skin to 0.13 mm into the interior of the circular-knit fabric is at least 30%.

The present invention relates to an aqueous poly(furfuryl alcohol) solution containing: from 40% to 85% by weight of poly(furfuryl alcohol), from 15% to 60% by weight of water and less than 1.5% by weight of furfuryl alcohol, said solution being characterized in that it exhibits a pH of greater than 7.0, preferably of between 7.2 and 10.0. The invention also relates to a process for the manufacture of a product based on mineral or organic fibers which are bonded by an organic binder, using such an aqueous poly(furfuryl alcohol) solution in the diluted form.
