Description

Technical Field

[0001] The invention relates to the technical field of protective gloves manufacturing, and in particular to a metal staple core-spun glove and a manufacturing process thereof. Background Art

[0002] Highly cut-resistant gloves often use yarns containing glass fiber or metal fiber as raw material yarns. The main method of use is to use all cut-resistant yarns as raw materials, or use hard yarns as the veil of gloves, and use fluffy attached yarns as the bottom yarn structure of gloves to increase comfort. However, first of all, it is difficult to avoid the irritation to the skin caused by occasional glass fiber breakage for cutting yarns made of glass fiber. If gloves containing steel wire yarns are purely woven, the steel wires will inevitably be exposed, which will seriously affect the feel. If steel wire yarns are used as veils and woven with bottom yarns, the influence of steel wires on the feel cannot be avoided. If steel wire yarns are woven on the rib surface and attached yarns are woven on the terry surface, the steel wires can still be easily felt in the terry surface, especially when the bottom yarn is not fluffy enough; if steel wires are woven on the terry surface and attached yarns are woven on the rib surface, the feel of the rib surface will be qualified, but the steel wires on the terry surface will be exposed very seriously, which will affect the external touch and dipping of the gloves.

[0003] Most of the main yarns of existing anti-isolation gloves are made of filaments, and the following problems often occur during use: the filaments are relatively sealed, hand sweat is not easy to drain out, the gloves become damp due to sweat, the friction between the hands and the gloves will be reduced, and the gloves are easy to fall off the hands, causing safety hazards. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a metal staple core-spun glove and a manufacturing process thereof, which solves the problems raised by the current background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A metal staple core-spun glove and a manufacturing process thereof, comprising a glove, wherein the glove comprises a glove wearing structure and a closing structure, wherein both the glove wearing structure and the closing structure are woven from finished yarn and auxiliary yarn, wherein an elastic rope is arranged inside the closing structure, and a composite polyester edge line is arranged at one end of the closing structure away from the glove wearing structure, wherein the finished yarn is woven from staple fiber-wrapped metal yarn, nylon high-elastic yarn, and polyether ester elastic fiber, and wherein the staple fiber-wrapped metal yarn is made of staple fiber and metal-wrapped polyester yarn through a core-spun process.

[0007] Preferably, the manufacturing process of the metal staple core-spun gloves comprises the following processing steps:

[0017] S10, second double twisting;

[0018] S11, finished product;

[0019] S12, knitting the finished yarn and the auxiliary yarn into gloves.

[0020] Preferably, the auxiliary yarn is one or more combinations of PPT fiber, spandex core-spun yarn, PBT high-elastic yarn, stretch yarn and nylon high-elastic yarn.

[0021] Preferably, the short fibers are set to have a length of 40-80 mm and a thickness of 1.5-3.0D, and are made of ultra-strong molecular weight polyethylene fibers or high-strength nylon fibers, or a mixture of one or both fibers.

[0022] Preferably, the S1 staple fiber pretreatment method is staple fiber screening, with a length cutting size of 55 mm and a thickness of 2D; pretreatment: immersing the obtained staple fibers in an auxiliary oil containing no silicone for 2-3 hours, wherein the auxiliary oil includes 30%-40% organic chelated titanium, 40%-50% epoxy fatty acid methyl ester, and 10%-20% manganese nitrate.

[0023] Preferably, the S7 self-winding step is to use high-pressure air to achieve connection between various short yarn nodes.

[0024] Preferably, the first doubling step S9 is: Z-twisting the short fiber-wrapped metal yarn, the nylon high-elastic yarn, and the polyetherester elastic fiber.

[0025] Preferably, the second double twisting step S9 is: subjecting the first double twisted product to S twisting.

[0026] Preferably, the polyetherester elastic fiber has a thickness of 15D-100D and a pulling multiple of 250%-300%.

[0027] Compared with the prior art, the beneficial effects achieved by the present invention are:

With reference to these contents, ordinary technicians in the field should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0034] According to an embodiment of the present invention, a metal staple core-spun glove and a manufacturing process thereof are provided.

[0035] Embodiment 1:

[0036] As shown in the attached figure of the instruction manual Figure 1 As shown, a metal staple core-spun glove and a manufacturing process thereof, comprising a glove 1, wherein the glove 1 comprises a glove wearing structure 2 and a closing structure 3, wherein the glove wearing structure 2 and the closing structure 3 are both woven from finished yarn and auxiliary yarn, an elastic rope is arranged inside the closing structure 3, and a composite polyester edge line 4 is arranged at one end of the closing structure 3 away from the glove wearing structure 2, wherein the finished yarn is woven from staple fiber-wrapped metal yarn, nylon high elastic yarn, and polyether ester elastic fiber, and the staple fiber-wrapped metal yarn is made of staple fiber and metal-wrapped polyester yarn through a core-spun process.

[0037] The staple length is set to 40-80mm, the thickness is 1.5-3.0D, and it is made of ultra-strong molecular weight polyethylene fiber or high-strength nylon fiber, one or a mixture of the two fibers. The staple length cutting size is 55mm, and the thickness is 2D. The staple fiber is wrapped with metal wire, which serves as the inner core, improving the wear and cut resistance of the finished gloves, and the protection level is high.

[0038] The auxiliary yarn can be one or more combinations of PPT fiber, spandex core-spun yarn, PBT high-elastic yarn, stretch yarn and nylon high-elastic yarn.

[0039] Embodiment 2:

[0040] A manufacturing process for metal staple fiber core-spun gloves, such as Figure 2 As shown, the processing steps are as follows:

[0041] S1. The pretreatment method of short fibers is short fiber screening, and the length cutting size is 55 mm and the thickness is 2D; pretreatment: the obtained short fibers are immersed in auxiliary oil without silicone for 2-3 hours, and the auxiliary oil is a mixed treatment auxiliary agent of 30%-40% organic chelated titanium, 40%-50% epoxy fatty acid methyl ester, and 10%-20% manganese nitrate.

[0042] S2. Opening and cleaning cotton: opening the compressed raw cotton into cotton bundles of about 0.05 mg; removing impurities and cotton knots mixed in the raw cotton, so that the impurity removal efficiency reaches 85%; mixing raw cotton of various grades evenly; making uniform cotton rolls or cotton bundles for use in the carding process.

[0043] S3, carding: opening the cotton bundles into single fibers, removing impurities and short fibers, and controlling the impurity content in the carded slivers at 0.01% to 0.1%; then the fibers are mixed and then formed into slivers.

[0044] S4, drawing: 4-6 slivers are combined to make the thick and thin sections of the slivers overlap randomly, so as to improve the uniformity of the finished sliver. The weight deviation of the yarn is controlled by drafting, and the sliver structure is improved at the same time, and the straightness and separation of the fibers are increased. The mixing between single fibers is achieved by repeated combining and drafting. Sliver mixing is often used to ensure that the cotton blending composition of the slivers is correct and uniform, and to avoid color difference after the yarn or fabric is dyed. The fiber layer after combining, drafting and mixing is then bundled and compressed to form finished slivers, and is regularly placed in the sliver can for easy handling and subsequent processing.

[0045] S5, roving: After the sliver enters the roving process, it is drafted 6-14 times, the sliver will be drafted, and the straight parallelism and separation of the fibers will be further improved. In the roving process, the drafted sliver is given an appropriate twist, which is conducive to strengthening the connection between the fibers in the sliver, so that the roving has a certain strength to withstand the tension when winding and unwinding the roving, and prevent accidental drafting or breaking. The twisted roving is wound on the bobbin to make a package of a certain shape and size, which is easy to carry and suitable for feeding into the spinning frame.

[0046] S6, Spun yarn: The fed roving is evenly drawn out and thinned, and metal filaments are wrapped in it. The stretched sliver is given an appropriate twist, so that the spun yarn has certain physical and mechanical properties such as strength, elasticity, gloss and feel. The twisted spun yarn is wound on a bobbin to make a package, which is easy to carry and suitable for subsequent processing.

[0047] S7, Self-winding: High-pressure air is used to connect the short yarn nodes, which reduces the flying catkins in the textile workshop, improves the quality of the working environment, and meets the health needs of the staff.

[0048] S8. Doubling: In order to ensure the quality of the strands after twisting, the strands must be doubling before twisting. Doubling requires that the yarn length of each single yarn is consistent to avoid uneven twist or small braided yarn.

[0049] S9, the first double twisting step is: short fiber wrapped metal yarn, nylon high elastic yarn, polyether ester elastic fiber Z twist double twist. The polyether ester elastic fiber is screened and selected to have a thickness of 15D-100D and a draft ratio of 250%-300%.

[0050] S10, the second twisting step is: the first twisting product is twisted in S twist, and the two twisting directions are opposite to avoid the problem of loose outer layer, and at the same time make the knitted gloves very beautiful and neat.

[0051] S11, finished product: finally forming the finished yarn.

[0052] S12. Weaving: Use one or more finished yarns as the main yarns, select auxiliary yarns, such as one or more combinations of PPT fiber, spandex core-spun yarn, PBT high-elastic yarn, stretch yarn and nylon high-elastic yarn, and weave the gloves according to the requirements of weaving density, screw tightness, unit volume density, etc.
