Description
Technical field
The invention belongs to compound insulating material, be specifically related to a kind of adopt compound insulating material that goat hair non-woven makes warp knitting technology preparation with and production method.
Background technology
The meat of goat, milk, skin, the goat cashmere that particularly is known as " soft gold " all is fully utilized, and wins good economic benefits.But, goats hair but because of thick and stiff, upright and outspoken, smooth, do not have to curl, cause that frictional force is little, coherent is poor, discrete, be difficult to into the net slivering, fail to become the raw material of modern textile industry, be able to fully rationally utilize.So, rest on felt among the people, system brush and manual twisting always and knit blanket.Last century, the nineties was as national problem, and many R﹠D institutions and enterprise have actively carried out the research and the exploration of goats hair modification, and have obtained better effects.Goats hair after modification obtains to a certain degree softening, generating unit is divided curling, and fiber surface frictional force increases, and makes it have spinnability, and by a certain percentage with fiber blend resultant yarns such as sheep's wool, viscose glue, acrylic fibers, processing drap-de-berry, clothes lining, carpet woven., fail to form bigger industrialized scale and with 100% modification goats hair processing.
Remove clothes and household textiles, fabrics for industrial use are another pillar industries of textile industry, and it is as a kind of means of production, says it is the development of supporting related industry as a kind of custom-designed structural timber more accurately.Along with technological progress and industrial upgrading, fabrics for industrial use have become most active and technical industries potentiality.Insulation material is exactly Application Areas fabrics for industrial use very widely, and industry, agricultural, transportation, the modern architecture industry all need insulation rate and the high insulation material of intensity.But the insulation material of conventional chemical fibre non-weaving cloth is difficult to satisfy the insulation rate under rigor condition and the requirement of intensity.Sheep's wool non-weaving cloth insulation rate can meet the demands, but has the low and higher problem of cost of intensity.Through the world, state's interconnect and data of optical disk library searching, yet there are no the report that useful goats hair is produced non-woven warp knitting composite insulation material.
Summary of the invention
