Problems solved by technology

However, the use and replacement cycle of the thickened woolen blanket is generally about one year. During the use period, the surface of the woolen blanket has cracks to varying degrees, which affects the shaping effect and is extremely expensive. As a consumable item, it greatly increases the manufacturing cost of the equipment. At the same time Increase the production cost of the manufacturer

Embodiment Construction

[0017] 1. Raw materials: filament, roving, wool top, wool, low temperature chemical fiber, high temperature chemical fiber;

[0018] 2. Fiber net: wool, low-temperature chemical fiber, and high-temperature chemical fiber are made into fiber nets by a netting mechanism, and they are ready for use;

[0019] 3. Spinning: Send the roving or wool sliver directly to the fine sand machine to form a single yarn through drafting and twisting, and set aside;

[0020] 4. Plying: combining and twisting two or more single yarns or filaments as warp and weft yarns;

[0021] 5. Twisting: Add a certain twist to wool strips or filaments, so that the fibers are closely entangled with each other, so as to improve the strength and elasticity of the yarn, and use it as warp and weft yarns;

[0022] 6. Diameter adjustment: Wind the specified number of warp yarns in parallel on the warp beam or the warp cylinder according to the specified length, and then wind the yarn from the warp cylinder to the...

Abstract

The invention relates to a manufacturing process of a knitted fabric preshrunk woolen felt. The manufacturing process is completed by the steps of raw material preparation, fiber web preparation, spinning, plying, twisting, beaming, fabric weaving, needling, after-finishing, product inspection and warehousing. In the manufacturing process of the knitted fabric preshrunk woolen felt provided by the invention, high-quality wool and high-performance fibers in forms of fiber layers are embedded into a composite base web layer by layer to produce a seamless annular felt; and high-temperature sizing and surface dressing techniques are adopted to ensure that the felt has the characteristics of smooth surface, reasonable internal structure, stable size, even thickness, softness and smoothness, high resilience, no creases and seams on the surface, soft and thick hand feeling and low shrinkage.

Description

[technical field] [0001] The invention relates to an industrial woolen blanket, in particular to a preparation process of a knitted fabric preshrunk woolen blanket. [Background technique] [0002] The stereotypes machine used by domestic and foreign textile enterprises has a good effect on the finishing of the opening width and the shape of the cylinder. However, the use and replacement cycle of the thickened woolen blanket is generally about one year. During the use period, the surface of the woolen blanket has cracks to varying degrees, which affects the shaping effect and is extremely expensive. As a consumable item, it greatly increases the manufacturing cost of the equipment. At the same time Increase the production cost of the production enterprise. [Content of the invention] [0003] In order to solve the above-mentioned disadvantages, the present invention provides a preparation process of a pre-shrunk knitted fabric blanket with reasonable internal structure, uni...
