CLOTH SPREADING APPARATUS
A cloth spreading apparatus has a spread the remainder of a piece of cloth to smooth out every wrinkle, without requiring a dedicated assistant worker, including: a conveyor belt receiving an upper side portion of a piece of cloth having been spread in a right-left direction, pulls the upper side portion rearward, sequentially pulls up the remainder from a middle to a lower side portion, and ejects the entire cloth rearward. Also, a wrinkle smoothing unit that smooths out wrinkles in the remainder while the conveyor belt pulls up the remainder. The wrinkle smoothing unit has a pair of wrinkle smoothing clamps that clamp right and left side portions of the remainder being pulled up by the conveyor belt, and wrinkle smoothing clamp moving mechanisms that move the clamps upward and apart from each other in the right-left direction while the cloth is pulled up by the conveyor belt.
Woven fabric with improved comfort
A woven fabric having a novel composition of multiple fibres with improved comfort and performance is disclosed. Further, a fabric composition, construction and crimp control process provides enhanced comfort and performance by improving parameters such as thermal conductivity and moisture regulation along with other parameters such as dimensional stability, smoothness, drying properties and tensile strength. The woven fabric includes a plurality of warp yarns and a plurality of weft yarns interwoven with said plurality of warp yarns, where the plurality of warp yarns is a blended spun yarn including cotton fibre and regenerated cellulose fibre. Each of the plurality of weft yarns is a continuous polyester filament of fine count. The woven fabric composition includes more than 50% cotton, 15-25% regenerated cellulose fibre and less than 35% polyester, further wherein moisture regain of the woven fabric is in the range of 5.5%-8.5%.

Process for steam drawing carbon-fiber precursor acrylic fiber bundle
This process for manufacturing a carbon-fiber precursor acrylic fiber bundle and this steam drawing apparatus are characterized in that the drawing of an acrylic fiber bundle with a pressured-steam drawing apparatus is conducted by: opening an acrylic fiber bundle by blowing a fluid thereto; supplying humidifying steam to the opened acrylic fiber bundle at a fiber temperature of 80 to 130 C. to adjust the water content of the fiber bundle to 3 to 7%; and thereafter drawing the resulting acrylic fiber bundle in a pressurized-steam atmosphere. Thus, the present invention can prevent the breaking of a single fiber, the fluffing of the fiber bundle, and the breaking of the whole of the fiber bundle, though such defects are susceptible to occurring in a case where an acrylic fiber bundle is drawn by steam drawing at a high draw ratio, at a higher speed, or into a fiber having a small denier.

PUCKERING STRETCHABLE FABRIC
Elastic thread lines can extend along borders of puckering areas of a fabric. The thread lines can include elastic thread line sections of the thread lines passing through thread line intersections and segments of the thread lines between the intersections. The elastic thread lines can bias the puckering areas in multiple different non-parallel directions toward a puckered configuration. In the puckered configuration, the puckering areas can be gathered together to pucker the fabric. The fabric can be stitched together to form a product, such as a sleeping bag sack that is stretchable in multiple orthogonal directions by stretching the thread lines. Elastic thread line sections passing through intersections can be made more secure by forming thread line section patterns that increase numbers of thread line crossings at the intersections. Densities of thread lines in different directions can be selected to produce different amounts of gathering, and for security.

CLOTH SPREADING APPARATUS
A cloth spreading apparatus is capable of eliminating the troublesome work of pulling a cloth when the cloth is held by feeding chucks to reduce burden of the worker and operation time. A cloth spreading apparatus includes a pair of feeding chucks grasping adjacent corners of a cloth, a moving device for moving the pair of feeding chucks between a feeding position and a delivery position of the cloth to draw the cloth, and spreading chucks for receiving the cloth directly or indirectly from the pair of feeding chucks and spreading the cloth in a direction of separating the adjacent corners from each other. The moving device has separate moving trajectories corresponding to the respective feeding chucks so that the pair of feeding chucks can move between the feeding position and the delivery position independently of each other.
