AI Technical Summary

Benefits of technology

The invention provides a garment with conductive fiber in the sewing thread, which prevents static electricity accumulation and friction during wearing and undressing. The amount of conductive fiber in the sewing thread is between 30% and 100% and in the woven or knitted fabric part is 1% or less. The friction charge amount is 0.8 μC / garment or less. The invention includes a method of sewing the garment with a sewing thread containing conductive fiber in the front body, back body, sleeves, and collar, with a content of conductive fiber in each part being 1% or less. The parts to be sewn include the side part, shoulder part, armhole part, collar part, sleeve part, cuff part, and hem part.

Problems solved by technology

Static electricity tends to accumulate in a heat-retention clothing for the winter season as a wearer moves, and electrostatic discharge emerged at the time of undressing leads to an uncomfortable feeling.
Though suppressing static electricity by antistatic treatment to clothing items is conventionally known, the antistatic function is deteriorated by repeating washing.
Further, though there is also a suppression method by incorporating a fiber having the antistatic capability into a woven or knitted fabric, a fiber having the antistatic capability is a colored fiber containing carbon, titanium oxide or metallic materials, and even when the fiber is dyed, a woven or knitted fabric having a brilliant color can not be obtained.
However, due to a covering with the sheath part consisting of the conductive fiber, it lacks homochromy after dying.

example 1

[0090]A spun yarn was manufactured by putting 100 mass % of conductive sheath-core type acrylic fiber (ET10 manufactured by Mitsubishi Rayon Co. Ltd., fineness: 3.3 dtex, fiber length: 38 mm) into a machine for a cotton spinning step. The conductive sheath-core type acrylic fiber contains conductive titanium oxide in the core part, and a content of conductive titanium oxide with respect to a total fiber is 12 mass %. At this time, since a single fiber strength is weak, the single fiber breakage occurs according to a draw ratio and the spinning rate in each step, which leads to the possibility of fray occurrence. Therefore, the spinning rate of a carding machine is set to be 40 m / minute or lower and a draw ratio of a draw frame is set to be 8 times. Spinning of the single spun yarn was conducted with a metric count of 32 and the number of twisting of 630 times / m in a spinning frame. As a sensor for measuring yarn evenness used in rolling the single spun yarn, not a normal capacitance...

example 2

[0094]A pink V neck sweater was obtained in the same manner as Example 1 except that a V-neck sweater was manufactured, and the dyeing after sewn was performed with a pale color, i.e. pink.

[0095]A frictional charge amount of the pink sweater was measured. The composition of the garment is shown in Table 1 and the evaluation result is shown in Table 2.

example 3

[0096]A sweater was obtained in the same manner as Example 1 except that the sewing thread A was used for sewing a sleeve part, a side part, a shoulder part and an armhole part, and as for sewing a collar part, a sewing thread not containing the conductive fiber was used instead of the sewing thread A, as shown in Table 1. The evaluation result is shown in Table 2.

Abstract

Provided is a garment that has an antistatic capability and exhibits washing durability without, when producing a woven or knitted fabric, using a conductive fiber at a part that becomes a wearing part of the woven or knitted fabric, and without applying an antistatic treatment to the woven or knitted fabric, but rather by incorporating a conductive fiber into a sewing thread. The garment according to the present invention has a conductive fiber incorporated in a sewing thread (linking thread), and has a frictional charge amount of 0.8 μC or less per garment. The garment preferably has an electric resistance value of 1×104Ω-5×108Ω per 1 cm length of the conductive fiber in a fiber axis direction thereof, and the sewing thread preferably includes the conductive fiber in an amount of 30-100 mass %.

Description

TECHNICAL FIELD[0001]A sewing thread (linking thread) used in sewing clothing items in the present invention is a thread in which a synthetic fiber having an antistatic capability and capable of being dyed is used, and the present invention also relates to a garment having the antistatic capability by using the thread.BACKGROUND ART[0002]Due to a recent improvement of an air conditioning installation, temperature is kept comfortable in a working room, while humidity is set to be low. In the winter, humidity is also low both in and out of a room.[0003]Static electricity tends to accumulate in a heat-retention clothing for the winter season as a wearer moves, and electrostatic discharge emerged at the time of undressing leads to an uncomfortable feeling. Though suppressing static electricity by antistatic treatment to clothing items is conventionally known, the antistatic function is deteriorated by repeating washing. Further, though there is also a suppression method by incorporating...
