A new type of non-machine-sewn (zero stitch) MLI blanket has been developed to achieve high thermal performance while maintaining workability of production and assembly equivalent to the conventional type. Tag-pins, which are widely used in commercial applications to hook price tags to products, are used to fix the films in place. The pin material is changed to polyetheretherketone (PEEK) for use in space. Thermal performance is measured using a boil-off calorimeter, in which a rectangular liquid nitrogen tank is used to evaluate the degradation at the bending corner and joint of the blanket. A test piece of zero-stich MLI shows significantly improved thermal performance (εeff is smaller than 0.0050 at ordinary temperature) despite having the same fastener interface as traditional blankets, while the venting design and number of tag-pins are confirmed as appropriate in depressurization test.

For conventional Multi-Layer Insulation (MLI) blankets, it is difficult to control the layer density and the thermal insulation performance degrades due to the increase in conductive heat leak through interlayer contacts. At low temperatures, the proportion of conductive heat transfer through MLI blankets is large compared to that of radiative heat transfer, hence the decline in thermal insulation performance is significant. A new type of MLI blanket using new spacers; the Non-Interlayer-Contact Spacer MLI (NICS MLI) has been developed. This new MLI blanket uses small discrete spacers and can exclude uncertain interlayer contact between films. It is made of polyetheretherketone (PEEK) making it suitable for space use. The cross-sectional area to length ratio of the spacer is 1.0 × 10-5 m with a 10 mm diameter and 4 mm height. The insulation performance is measured with a boil-off calorimeter. Because the NICS MLI blanket can exclude uncertain interlayer contact, the test results showed good agreement with estimations. Furthermore, the NICS MLI blanket shows significantly good insulation performance (effective emissivity is 0.0046 at ordinary temperature), particularly at low temperatures, due to the high thermal resistance of this spacer. © 2014 Elsevier Ltd.

A zipper member has a receiving portion having an insertion hole formed therein and including a locking portion, and an inserting portion having an engaging portion to be inserted into the insertion hole of the receiving portion and engaging with the locking portion to establish a locking state. A filament portion integrally connects the receiving portion to the inserting portion. An IC chip is mounted in a holding portion of the zipper member, the holding portion being formed of a hard material along a portion of the filament portion. An attachment tool includes a runner member on which an assembly of zipper members are placed in parallel at regular intervals to be cuttable. The attachment tool sequentially attaches the zipper members to a target one by one.
