CUT/SEWN GLOVES Cut/Sewn Gloves are produced by assembling glove parts cut from bulk materials such as fabric, coated fabric, and/or leather. Disadvantages DIPPED/UNSUPPORTED GLOVES Dipped/Unsupported Gloves are produced by dipping ceramic hand “forms” into a liquid material that congeals on the hand form to make a glove. The base material is some form of rubber, synthetic rubber, or plastic, formulated to achieve the desired barrier and performance characteristics. SEAMLESS KNIT GLOVES Seamless Knit Gloves are produced by an automatic knitting process to convert bulk yarn to a finished glove, often reinforced with a coating. Advantages Disadvantages DIP-COATED/SUPPORTED GLOVES Dip-Coated/Supported Gloves are produced by coating a fabric glove liner (either cut/sewn or seamless knit) with some form of rubber, synthetic rubber, or plastic, formulated to achieve the desired performance characteristics. The lining provides a base to which the coating is bonded and usually enhances physical performance. ©2014 Saf-T-Gard International, Inc. Advantages A great deal of versatility in combining materials and design/style options. Exposed seams can be both uncomfortable and a wear/failure area; fit may not be ideal due to the manufacturing process of making a 3-dimensional glove from 2-dimensional materials; size inconsistency is possible due to the human element of sewing. Knitted products generally conform better to wearer’s hands; a great deal of versatility is possible in blending and matching yarns to different gauge knitting machines (standard, fine, extra-fine) to achieve desired glove performance; uncoated styles and screen-coated styles can fit either hand so that any 2 gloves makes a pair. Uncoated styles have no puncture and limited snag protection due to the knitting process; thumb and finger crotch areas are potential weak spots due to the technology of the knitting process and stretching to fit the wearer’s hand. Extensive test data is generally available to identify glove material Advantages performance in many chemicals; the ceramic hand “forms” allow for gloves of a natural hand shape; a variety of glove lengths are available; a grip-enhancing texture can be incorporated into the hand form. Chemical protection is often a trade-off for physical hazard Disadvantages protection (cut, snag, puncture, abrasion) - a lack of fabric lining limits the glove’s resistance to tears and snags to the inherent strength of the base material; the glove size range is limited to the hand forms in the manufacturer’s range and size modifications; custom products are not practical to produce. Gloves can be fully coated to be liquid proof and achieve similar chemical Advantages resistance to dipped/unsupported gloves of the same outer material; gloves can be partially coated (palm coated or flat-dipped) so that the back of the glove is uncoated for wearer comfort while the coating protects the palm, thumb, and fingers; a wide variety of coatings can be matched to base materials to achieve the desired performance; a grip-enhancing texture can be added to the coating. The glove size range is limited to the hand forms in Disadvantages the manufacturer’s range and size modifications and custom products are not practical to produce.
