[0058]
[0059] Spinning sliver after combing process made of regenerated cellulose (cuprammonium fiber: manufactured by Asahi Kasei Co., Ltd., trade name "Bemberg", single fiber fineness 1.4 dtex, fiber length 38 mm) (mass per unit length, unit Grain: 21.0g / 6yd (3.8g / m)) is taken out from the container, and is continuously supplied to an electron curtain type electron beam irradiation device EC250 / 15 / 180L (manufactured by Iwasaki Electric Co., Ltd.), and a nitrogen atmosphere is contained in the device Electron beams of 20 kGy were irradiated. The sliver irradiated with electron beams was then continuously dipped in a 10% by mass aqueous solution of acrylic acid (manufactured by NACALAI TESQUE, INC.), and rolled with a squeezer to a squeeze rate of about 100% by mass relative to the weight of the sliver. As a result, 10% by mass of acrylic acid was imparted to the fibers of the sliver. Next, the above-mentioned sliver was continuously heat-treated with steam at 100°C for 1...

Abstract
Provided are: a sliver having the function of deodorization and / or the function of generating heat upon moisture absorption; a process for efficiently and rationally producing the sliver; and a spun yarn and a textile product both obtained using the sliver. The sliver for spinning, which has the function of deodorization and / or the function of generating heat upon moisture absorption, is obtained by arranging short fibers in one direction, collecting the fibers together into a strand, irradiating the resultant sliver for spinning with electron rays to impart active groups to the fiber surface and / or generate radicals on the fiber surface, and bonding a compound containing an ethylenically unsaturated double bond to the surface of the fibers. The spun yarn is obtained by subjecting the sliver for spinning to fine spinning or by subjecting the sliver to fine spinning together with other sliver(s), and has the function of deodorization and / or the function of generating heat upon moisture absorption. The textile product is a textile product comprising the spun yarn and having the function of deodorization and / or the function of generating heat upon moisture absorption.
Description
technical field [0001] The present invention relates to a sliver having a deodorizing function and / or a moisture-absorbing and heat-releasing function, a manufacturing method thereof, a spun yarn and a fiber product using the same. Background technique [0002] Hygroscopic exothermicity is the property of dry fibers to release heat when they absorb moisture (moisture). For example, even if the quilt brought back to the room after being exposed to the sun during the day reaches the same temperature as the room temperature after several hours, people will feel warm when it touches the skin of the human body. This phenomenon is known to be due to the fibers of the quilt. Produced by moisture absorption and heat release. [0003] Conventionally, as methods for producing moisture-absorbing and heat-releasing fibers, the following Patent Documents 1 and 2 propose highly moisture-absorbing and releasing fibers comprising acrylonitrile fibers subjected to hydrazine crosslinking tre...
