摘要:
A process for producing woven or knitted fabrics having an improved fastness, high qualities, and the width as large as 150 cm from yarn-dyed raw silk while evading possible occurrence of defects caused by piece dyeing, such as shading, friction marks, creases or bending. The process comprises the step (3) of union dyeing of sericin which surrounds the silk and fibroin which is contained within the silk, the steps (4 and 5) of preparing yarn-dyed raw silk by doubling the dyed silk fibers followed by twisting, the step (6) of producing fabric by weaving or knitting the yarn-dyed raw silk, the step (7) of swelling the raw silk constituting the fabric in a hot-water bath, and the step (8) of enzymatic degumming by treating the fabric with an enzyme capable of hydrolyzing the sericin of the swollen yarn-dyed raw silk.

Reforming of woven/knitted fabrics is effected by applying a skeletal triazine cross-linking reaction by using a sericin fixation method of raw silk so as to improve shrinkage resistance, crease resistance and shape stability, and then sericin is removed by specific refining to obtain woven/knitted fabrics. A production method of woven/knitted fabrics comprises a step of processing and treating raw silk and/or cellulose fiber by using a sericin fixation method of raw silk, a step of doubling and twisting the raw silk and/or cellulose fiber so processed and treated by the sericin fixation method, a weaving and knitting step using the yarns so doubled and twisted, a swelling step of immersing the fabric into a tank to swell the woven/knitted fabric constituting a piece of cloth and a step of effecting enzymic refining for the woven/knitted fabric swelled inside the tank, and this method imparts shrinkage resistance, crease resistance and shape stability to the knitted/woven fabric.

Upon a request from a concerned trader including a seller, a buyer and a transporter, a user registering unit registers in a data base the user registration information containing a public key certificate acquired by each trader from an administering authentication office. A transfer registering unit changes the owner of the cargo information registered in the database at the trade starting time into another trader on the basis of the request for the registration change of the trader attached with a digital signature and the public key certificate. A verification unit verifies that the digital signature attached to the change registration request has been created by a secret key pairing with the public key certificate registered in the database, and validates the transfer registration having a legal binding force if the approval of the partner is acquired.
摘要:
The present invention relates to a hot-rolled steel sheet, a cold-rolled steel sheet, and a plated steel sheet having improved uniform ductility and local ductility at a high strain rate. A multi-phase hot-rolled steel sheet according to one mode of the present invention has a metallurgical structure having a main phase of ferrite with an average grain diameter of at most 3.0 µm and a second phase including at least one of martensite, bainite, and austenite. In the surface layer, the average grain diameter of the second phase is at most 2.0 µm, the difference (”nH av ) between the average nanohardness of the main phase (nH ±av ) and the average nanohardness of the second phase (nH 2nd av ) is 6.0 - 10.0 GPa, the difference (”ÃnH) of the standard deviation of the nanohardness of the second phase from the standard deviation of the nanohardness of the main phase is at most 1.5 GPa, and in the central portion, the difference (”nH av ) between the average nanohardnesses is at least 3.5 GPa to at most 6.0 GPa and the difference (”ÃnH) between the standard deviations of the nanohardnesses is at least 1.5 GPa.
