An article forming pet gear appointed to be worn by a pet, including pet coats, jackets, shirts or sweaters, has a plurality of interchangeable attachments appointed to modify the article's look, feel and function. The article comprises a proximal end, distal end and a central section having at least one connection means appointed to receive the interchangeable attachment. The interchangeable attachment includes a top wall having a show surface and a back wall having a securing member adapted to engage with the connection means of the article for removably attaching the interchangeable attachment to the article. The interchangeable attachments have a plethora of designs and may include LED, fiber optic and / or reflective properties to provide aesthetic appeal, the ability to design one's own accessory, enhanced visibility, and / or increased safety of the pet during nighttime or dusk hours. They may also be treated with insect repellent, fragrance enhancers, and / or water repellant agents; and layered to provide increased warmth or a cooling effect to accommodate for changes in weather conditions.

A compressible insulating material for use in active garments and other gear is provided herein. The material comprises an insulating material including one or more types of fiber, with portions of the insulating material removed or cut to improve the warmth-to-weight and compression characteristics of the insulating material. In some embodiments, the insulating material is an elastic insulating material that defines perforations or other features that expand or contract depending on stretching or relaxation of the elastic insulating material. Stretching and relaxation may vary an insulating property of the compressible, low-weight insulating material. The material may further be secured to a stretch-resistant material to provide a reference point for stretching and for and elastic memory. A garment comprising one or more panels of a compressible, low-weight insulating material as described herein is also provided. Strategic placement of the insulating material can improve ventilation of the garment during activities.

The invention discloses a manufacturing technology for far-infrared polyester short fibers, which takes recycled PET (Polyethylene Terephthalate) as a raw material, and the recycled PET is processed sequentially through pretreatment, rotating drum drying, melt spinning, cooling formation, winding, drawing, curling, oil application, cutting and heat setting, so as to obtain finished products, wherein in the rotating drum drying step, the recycled PET is dried for 5.5 to 6.5 hours firstly, then far-infrared master batches are added, the final mass fraction of the far-infrared master batches ranges from 5 to 7 percent, the total drying time ranges from 9.5 to 10.5 hours, and far-infrared ceramic powders account for 19 to 21 percent in the far-infrared master batches; in the melt spinning step, the temperatures of a screw bolt and a spinning box body of a screw bolt extruder range from 268 to 278 DEG C, and cooling formation is carried out through circular air blow; in addition, the total drawing ratio is 3.0 to 3.5, the heat setting temperature ranges from 162 to 168 DEG C, and the heat setting time ranges from 8 to 12 minutes. The manufacturing technology can save cost and is beneficial to environmental protection, and the prepared finished products achieve good warmth retention and health protection properties.

The invention relates to a three-dimensional loop flannelette shell fabric and a preparation method thereof. The shell fabric is in a plating lining loop structure, the shell yarn is pure cotton combed yarn, the middle connecting yarn is filament polyester fiber, and the velvet lining yarn is polyester and cellulosic fiber blended yarn or pure cotton yarn. The preparation method comprises the steps of untwisting, knitting, fabric slitting, curling and finishing, rubber carpet shrunk finishing, and dyeing finishing. The three-dimensional loop flannelette shell fabric recovers the characteristics that ordinary non-napping loop flannelette is not ordered enough in loop and not fluffy enough for hand feeling, the thickness and heat retention property of the shell fabric are increased, and the additional value of the product is improved, so that the three-dimensional loop flannelette shell fabric is more advantageous in market competition, and is low in cost, simple in technology and good in market prospect.

An ambient light is produced by transmitting light from a light source through an optical diffusion layer and then through a wood veneer. The optical diffusion layer obscures the light source and distributes the light transmitted through the wood veneer. The light then filters through the wood veneer via the color and grain of the wood. The light emitted from the wood veneer has natural colors that produce a warm ambient light.

A shawl including a sheet of fabric having an inner surface and an outer surface defined by a top edge, a bottom edge, a right side edge and a left side edge. The sheet of fabric is dimensioned to allow the right and left hands of the user to each extend beyond the right edge and left edge of the sheet of fabric when the top edge of the sheet of fabric is draped over the user's shoulders. A right arm closure extends from the inner surface of the sheet of fabric proximate to the right edge, and a left arm closure extending from the inner surface of the sheet of fabric proximate to the left edge. Each of the arm closures has a width that is less than a width of a human forearm and defines an opening dimensioned to allow the user's hands to pass therethrough.

A thermally insulated hammock is provided with a pair of insulation retaining panels, one secured to either side of the hammock bed. The panels can be drawn across the bottom surface of the hammock and fastened so as to hold one or more insulation pads against the bottom surface of the hammock bed in cold weather. The retaining panels may be rolled up out of the way and tied at the edges of the hammock when insulation is not needed.
