Definitions

  • This invention relates to knitwear, and in particular to knitted work gloves.
  • Work gloves can be classified into different categories. Depending on the material from which they are made, gloves can be textile, rubber, knitted, leather or combined. Depending on the manufacturing method, each glove can be made in whole, sewn from two halves or in parts made separately from each other.
  • Short-term thermal protection is needed in situations where sudden temperature jumps are possible due to interaction with hot surfaces, flames, sparks, or extremely low temperatures. Long-term thermal protection is usually required in cold weather.
  • Vibration protection provides safe operation with vibrating devices that could be harmful to hands. Examples of such devices include trimmers, drills, jack hammers and other tools.
  • a knitted fabric in knitted gloves is usually thin, has a low linear density (approximately 200 tex), and is made of one or two materials.
  • a knitted glove without a polymer coating may be convenient to use, however, to provide protection from the above-mentioned hazards, a multilayer polymer coating is usually required, which significantly reduces usability. Coverage also does not provide protection against all factors.
  • This invention relates to knitted work gloves and methods for their production, overcoming some of the disadvantages of prior art solutions.
  • the glove and method according to the invention also have additional advantages and technical effects.
  • a knitted glove comprising a knit of five or more threads made of three or more different materials.
  • Five or more threads include one or more primary reinforcing threads, one or more secondary reinforcing threads, and one or more main threads.
  • Knitwear for a glove of five or more threads is made of a composite knitted material made of five or more threads (that is, from a bundle of threads in which five or more threads).
  • the number of threads of a certain type in the glove represents their proportion in the material with respect to threads of other types.
  • linear density of threads from a certain material in a knitwear directly depends on the total number of threads from this material, however, each individual thread can have a linear density that differs from the linear density of other threads.
  • the linear densities of the threads most clearly reflect the proportions of each of three or more materials in the glove’s knitwear, so the linear densities will be used in the present description along with the number of threads used in the manufacture of the glove.
  • the primary reinforcing yarns defines the basic protective properties of a knitted glove.
  • Basic protective properties may include mechanical, vibrational or thermal protection, or any combination of these properties.
  • the primary reinforcing threads can be made of various reinforcing materials that provide these protective properties, as described below in the description of embodiments of the invention.
  • Secondary reinforcing threads have lower linear density and greater flexibility than primary reinforcing threads. This means, among other things, that individual secondary reinforcing threads are thinner than individual primary reinforcing threads. The lower linear density and thickness allow the secondary reinforcing yarns to occupy the space between the denser primary reinforcing yarns and the main yarns. Secondary reinforcing threads may also surround other threads and / or bind primary reinforcing threads to the main threads. This improves the protective properties of the glove, as the material becomes more durable and densely filled, and the elasticity of the glove does not deteriorate.
  • the warp yarns contain a soft warp material that defines the elastic and ergonomic properties of a knitted glove. These properties may include tactile sensations, elasticity in all directions, and breathability to prevent palm sweating.
  • the elasticity of the warp threads, combined with the protective properties of the reinforcing threads, can also enhance resistance to cuts, abrasion and punctures.
  • Each individual main yarn has a linear density of 20 to 125 tex
  • each individual primary reinforcing thread has a linear density of 20 to 150 tex
  • each individual secondary reinforcing thread has a linear density of 2 to 50 tex - this value is always lower, than the linear density of each individual primary reinforcing thread.
  • the total (total) linear density of five or more threads contained in a knitted glove is from 320 to 450 tex.
  • the total linear density of the main threads may be higher than the total linear density of all other threads.
  • Such a combination of linear density ranges by type of yarn, and the indicated total linear density provide optimal protective properties of the glove. These properties may include any combination of: protection from cuts, abrasion, punctures, tearing gloves; protection against fire or other sudden temperature changes; protection against short-term effects of various liquids; vibration protection; and protection against dirt and dust.
  • a set of five or more threads makes it easy to achieve a total linear density of 320 to 450 tex. The number of threads of more than five gives the best mechanical and other protective properties of the glove than a glove with fewer threads, but the same overall linear density. The combination of different types of threads further enhances the knitted fabric.
  • the number of different materials of which the threads are made provide the above properties of each of the threads, and also allow to achieve a total linear density of from 320 to 450 tex, while maintaining comfort when wearing a glove.
  • the number of different materials is selected based on: the number of threads, the optimal proportions, the protective properties and the comfort of the glove. Different materials can also contribute to the improvement of various protective properties, for example, a fire-resistant material makes the entire glove resistant to fire. By changing the proportions of the materials and yarns of each type used in a knitted glove, it is possible to adjust the protective and ergonomic properties.
  • the total number of threads is between 5 and 20. Knitwear containing more than 20 threads can also be used, but in most cases adding more than 20 threads is not required. More threads in the glove means that the knitwear is more tightly filled.
  • the total number of different materials can be from 3 to 10.
  • the total linear density of one or more warp yarns can be from 200 to 350 tex
  • the total linear density of one or more primary reinforcing yarns can be from 50 to 150 tex
  • the total linear density of one or more secondary reinforcing yarns can be from 8 up to 70 tex.
  • This proportion of linear densities can mean the optimal combination of comfort and protective features. This proportion also allows to reduce the frequency of formation of defects during the production of gloves due to the uniform filling of the knitted fabric, which is formed at the indicated linear densities.
  • the main thread may further include polyester. Cotton threads with polyester are more wear resistant.
  • the primary reinforcing thread includes primary reinforcing material. This material can be selected from the following materials: polypropylene, aramids, basalt fiber, silica fiber, fiberglass, carbon fiber, and any combination thereof. Aramids include para-aramids and other aramid fibers. The materials from this list provide good protective properties of the glove, and strong threads are obtained from them.
  • the secondary reinforcing thread includes a secondary reinforcing material selected from the following materials: polyamide, polyester, elastane, acrylic, nylon, and any combination thereof. These materials can be quite thin and have a low linear density in comparison with primary reinforcing materials. At the same time, these materials are resistant to abrasion and tearing.
  • the knitted glove may be coated with a polymer coating to improve its protective properties.
  • a method for manufacturing a knitted glove with a knitting apparatus includes: feeding into the yarn guide of a knitting apparatus a bundle of threads comprising five or more threads made of three or more different materials; knitting from a bundle of threads at least eight parts of the glove at a predetermined speed, and at least eight parts include: first finger, second finger, third finger, fourth finger, palm part adjacent to the first four fingers, thumb, pre-cuff section, adjacent with palm and thumb, and elastic cuffs.
  • the method also includes binding the adjacent parts of the glove at a speed at least 4 times lower than the predetermined speed of knitting the parts of the glove.
  • the bonding of adjacent parts at a speed at least 4 times lower than the main knitting speed provides increased accuracy when performing complex operations, “holding” the glove.
  • the beginning of each of the knitting operations of the individual parts, for example fingers can be performed at a speed at least 4 times lower than the main knitting speed. This reduces the number of defects at the fingertips of the glove, because knitting the fingertips of the glove is a complex operation.
  • the method may also include applying a polymer coating to the glove by pressing or spraying under pressure, and then baking. Indentation or spraying under pressure provides uniform coverage over the surface of the glove, and reduces the consumption of polymer coating. The coating can be absorbed into the glove, essentially saturating the knitted fabric with a polymer coating and thereby forming a new composite glove material.
  • the method also includes processing the cuff of the glove with an overlock. This operation allows you to complete the cuffs with an “elastic band”, which helps to keep the glove on your wrist. Overlock also protects the glove from self-dissolving.
  • the method may also include separating the first, second, third, fourth and thumb from the yarn guide by cutting the bundle of threads. This allows you to do operations separately, and redo them in case of defects.
